Sample records for early aneurysm surgery

  1. Abdominal aortic aneurysm surgery

    Gefke, K; Schroeder, T V; Thisted, B


    The goal of this study was to identify patients who need longer care in the ICU (more than 48 hours) following abdominal aortic aneurysm (AAA) surgery and to evaluate the influence of perioperative complications on short- and long-term survival and quality of life. AAA surgery was performed in 553......, 78% stated that their quality of life had improved or was unchanged after surgery and had resumed working. These data justify a therapeutically aggressive approach, including ICU therapy following AAA surgery, despite failure of one or more organ systems....

  2. Subarachnoid hemorrhage after aneurysm surgery

    Carlos Gilberto Carlotti Junior


    Full Text Available The surgical treatment of intracranial aneurysms by clipping is recognized as effective and definitive. However some cases that suffered a new subarachnoid hemorrhage (SAH some time after they were submitted to aneurysm clipping have raised doubts about the concept of "cure"after this treatment. Eleven patients previously submitted to aneurysm clipping who presented a new SAH were analyzed. The time elapsed from surgery to SAH varied from 3 to 10 years. After SAH four patients had a poor outcome. The new episode of SAH occurred due to intrinsic factors of the cerebral vasculature: 1. a weak point of the vessel wall near the previous aneurysm, 2. a weak point of another vessel far from the previous aneurysm, 3. a previous infundibular dilation of the posterior communicating artery; and due to technical problems: 1. aneurysm not identified during the previous treatment, 2. aneurysm deliberately left untreated, 3. persistence of the aneurysm due to inappropriate surgery, 4. persistency of part of the aneurysm neck after clipping and 5. slipping of the clip from the neck of the aneurysm. The measures to prevent new SAH after surgery start with adequate preoperative angiographic studies, a careful inspection of the position of the clip and emptying of the aneurysm. Early angiography studies may reveal a persistent neck and later ones may reveal newly developed aneurysms. In conclusion, SAH after aneurysm clipping is a late and severe phenomenon and the concept of "cure" after this surgery should be interpreted with caution.O tratamento cirúrgico dos aneurismas cerebrais através de sua clipagem é reconhecido como eficaz e definitivo. Entretanto alguns casos sofrem nova hemorragia algum tempo após a cirurgia, deixando dúvidas sobre a "cura" pelo tratamento. Onze pacientes submetidos anteriormente a clipagem do aneurisma e que apresentaram nova hemorragia foram analisados. O intervalo de tempo da cirurgia para a nova hemorragia foi de 3 a 10 anos

  3. History, Evolution, and Continuing Innovations of Intracranial Aneurysm Surgery.

    Lai, Leon T; O'Neill, Anthea H


    Evolution in the surgical treatment of intracranial aneurysms is driven by the need to refine and innovate. From an early application of the Hunterian carotid ligation to modern-day sophisticated aneurysm clip designs, progress has been made through dedication and technical maturation of cerebrovascular neurosurgeons to overcome challenges in their practices. The global expansion of endovascular services has challenged the existence of aneurysm surgery, changing the complexity of the aneurysm case mix and volume that are referred for surgical repair. Concepts of how to best treat intracranial aneurysms have evolved over generations and will continue to do so with further technological innovations. As with the evolution of any type of surgery, innovations frequently arise from the criticism of current techniques. Copyright © 2017 Elsevier Inc. All rights reserved.

    Tirakotai, Wuttipong; Sure, Ulrich; Yin, Yuhua; Benes, Ludwig; Schulte, Dirk Michael; Bien, Siegfried; Bertalanffy, Helmut


    To perform a retrospective study on the patients who underwent aneurysmal surgery following endovascular treatment. We performed a retrospective study on eight patients who underwent aneurysmal surgery following endovascular treatment (-attempts) with gugliemi detachable coils (GDCs). The indications for surgery, surgical techniques and clinical outcomes were analyzed. The indications for surgical treatment after GDC coiling of aneurysm were classified into three groups. First group: surgery of incompletely coiled aneurysms (n=4). Second group: surgery of mass effect on the neural structures due to coil compaction or rebleeding (n=2). Third group: surgery of vascular complications after endovascular procedure due to parent artery occlusion or thrombus propagation from aneurysm (n=2). Aneurysm obliterations could be performed in all cases confirmed by postoperative angiography. Six patients had an excellent outcome and returned to their profession. Patient's visual acuity was improved. One individual experienced right hemiparesis (grade IV/V) and hemihypesthesia. Microsurgical clipping is rarely necessary for previously coiled aneurysms. Surgical treatment is uncommonly required when an acute complication arises during endovascular treatment, or when there is a dynamic change of a residual aneurysm configuration over time that is considered to be insecure.

  5. Early inflammatory response following elective abdominal aortic aneurysm repair: A comparison between endovascular procedure and conventional, open surgery

    Marjanović Ivan


    Full Text Available Background/Aim. Abdominal aorta aneurysm (AAA represents a pathological enlargment of infrarenal portion of aorta for over 50% of its lumen. The only treatment of AAA is a surgical reconstruction of the affected segment. Until the late XX century, surgical reconstruction implied explicit, open repair (OR of AAA, which was accompanied by a significant morbidity and mortality of the treated patients. Development of endovascular repair of (EVAR AAA, especially in the last decade, offered another possibility of surgical reconstruction of AAA. The preliminary results of world studies show that complications of such a procedure, as well as morbidity and mortality of patients, are significantly lower than with OR of AAA. The aim of this paper was to present results of comparative clinical prospective study of early inflammatory response after reconstruction of AAA between endovascular and open, conventional surgical technique. Methods. A comparative clinical prospective study included 39 patients, electively operated on for AAA within the period of December 2008 - February 2010, divided into two groups. The group I counted 21 (54% of the patients, 58-87 years old (mean 74.3 years, who had been submited to EVAR by the use of excluder stent graft. The group II consisted of 18 (46% of the patients, 49-82 (mean 66.8 years, operated on using OR technique. All of the treated patients in both groups had AAA larager than 50 mm. The study did not include patients who have been treated as urgent cases, due to the rupture or with simptomatic AAA. Clinical, biochemical and inflamatory parameters in early postoperative period were analyzed, in direct postoperative course (number of leucocytes, thrombocytes, serum circulating levels of cytokine - interleukine (IL-2, IL-4, IL-6 and IL-10. Parameters were monitored on the zero, first, second, third and seventh postoperative days. The study was approved by the Ethics Commitee of the Military Medical Academy. Results

    Kalani, M Yashar S; Elhadi, Ali M; Ramey, Wyatt; Nakaji, Peter; Albuquerque, Felipe C; McDougall, Cameron G; Zabramski, Joseph M; Spetzler, Robert F


    Aneurysms are relatively rare in the pediatric population and tend to include a greater proportion of large and giant lesions. A subset of these large and giant aneurysms are not amenable to direct surgical clipping and require complex treatment strategies and revascularization techniques. There are limited data available on the management of these lesions in the pediatric population. This study was undertaken to evaluate the outcome of treatment of large and giant aneurysms that required microsurgical revascularization and vessel sacrifice in this population. The authors retrospectively identified all cases in which pediatric patients (age aneurysms were treated using cerebral revascularization in combination with other treatment modalities at their institution between 1989 and 2013. The authors identified 27 consecutive patients (19 male and 8 female) with 29 aneurysms. The mean age of the patients at the time of treatment was 11.5 years (median 13 years, range 1-17 years). Five patients presented with subarachnoid hemorrhage, 11 with symptoms related to mass effect, 2 with stroke, and 3 with seizures; in 6 cases, the aneurysms were incidental findings. Aneurysms were located along the internal carotid artery (n = 7), posterior cerebral artery (PCA) (n = 2), anterior cerebral artery (n = 2), middle cerebral artery (MCA) (n = 14), basilar artery (n = 2), vertebral artery (n = 1), and at the vertebrobasilar junction (n = 1). Thirteen were giant aneurysms (45%). The majority of the aneurysms were fusiform (n = 19, 66%), followed by saccular (n = 10, 34%). Three cases were previously treated using microsurgery (n = 2) or an endovascular procedure (n = 1). A total of 28 revascularization procedures were performed, including superficial temporal artery (STA) to MCA (n = 6), STA to PCA (n = 1), occipital artery to PCA (n = 1), extracranial-intracranial (EC-IC) bypass using radial artery graft (n = 3), EC-IC using a saphenous vein graft (n = 7), STA onlay (n = 3), end

  7. Practicability of intraoperative microvascular Doppler sonography in aneurysm surgery.

    Firsching, R; Synowitz, H J; Hanebeck, J


    Inadvertent narrowing of parent or branching vessels is one major cause of unfavorable outcome from aneurysm surgery. Intraoperative micro-Doppler sonography of arterial brain vessels during surgery for cerebral aneurysms of the anterior circulation was performed in 50 patients and compared retrospectively with 50 patients, who were operated upon without micro-Doppler sonography. Intraoperative micro-Doppler sonography demonstrated the need for repositioning of the clip in 12 instances. Outcome after surgery with micro-Doppler sonography appeared slightly better than without. Micro-Doppler sonography is concluded to be a practicable adjunct to routine aneurysm surgery.

    Background Surgical treatment of intracranial aneurysms is often compromised by incomplete exclusion of the aneurysm or stenosis of parent vessels.Intraoperative microvascular Doppler (IMD) is an attractive,noninvasive,and inexpensive tool.The present study aimed to evaluate the usefulness and reliability of IMD for guiding clip placement in aneurysm surgery.Methods A total of 92 patients with 101 intracranial aneurysms were included in the study.IMD with a 1.5-mm diameter,20-MHz microprobe was used before and after clip application to confirm aneurysm obliteration and patency of parent vessels and branching arteries.IMD findings were verified postoperatively with digital subtraction angiography (DSA) or dual energy computed tomography angiography (DE-CTA).Ninety consecutive patients,harboring 108 aneurysms,who underwent surgery without IMD was considered as the control group.Results The microprobe detected all vessels of the Circle of Willis and their major branches.Clips were repositioned in 24 (23.8%) aneurysms on the basis of the IMD findings consistent with incomplete exclusion and/or stenosis.IMD identified persistent weak blood flow through the aneurismal sac of 11 of the 101 (10.9%) aneurysms requiring clip adjustment.Stenosis or occlusion of the parent or branching arteries as indicated by IMD necessitated immediate clip adjustment in 19 aneurysms (18.8%).The mean duration of the IMD procedure was 4.8 minutes.The frequency of clip adjustment (mean:1.8 times per case) was associated with the size and location of the aneurysm.There were no complications related to the use of IMD,and postoperative angiograms confirmed complete aneurysm exclusion and parent vessel patency.About 8.3% (9/108) aneurysms were unexpectedly incompletely occluded,and 10.2% (11/108) aneurysms and parent vessel stenosis without IMD were detected by postoperative DSA or DE-CTA.IMD could reduce the rate of residual aneurysm and unanticipated vessel stenosis which demonstrated

  9. Harvey W. Cushing and cerebrovascular surgery: Part I, Aneurysms.

    Cohen-Gadol, Aaron A; Spencer, Dennis D


    The development of surgical techniques for the treatment of intracranial aneurysms has paralleled the evolution of the specialty of neurological surgery. During the Cushing era, intracranial aneurysms were considered inoperable and only ligation of the carotid artery was performed. Cushing understood the limitations of this approach and advised the need for a more thorough understanding of aneurysm pathology before further consideration could be given to the surgical treatment of cerebral aneurysms. Despite his focus on brain tumors, Cushing's contributions to the discipline of neurovascular surgery are of great importance. With the assistance of Sir Charles Symonds, Cushing described the syndrome of subarachnoid hemorrhage. He considered inserting muscle strips into cerebral aneurysms to promote aneurysm sac thrombosis and designed the "silver clip," which was modified by McKenzie and later used by Dandy to clip the first intracranial aneurysm. Cushing was the first surgeon to wrap aneurysms in muscle fragments to prevent recurrent hemorrhage. He established the foundation on which pioneers such as Norman Dott and Walter Dandy launched the modern era of neurovascular surgery.

  10. Cranio-orbital approach for complex aneurysmal surgery.

    Kelleher, M O


    Certain aneurysms of the anterior circulation continue to offer a technical challenge for safe exposure and clipping. The purpose of this paper was to describe the cranio-orbital approach for surgical clipping of complex aneurysms and to evaluate prospectively the associated complications of this approach. Prospective audit of all patients undergoing cranio-orbital approach for aneurysm surgery from 1997 to 2004 by the senior author. Twenty-five patients, eight male and 17 female, median age of 52 years, range 28-73. All patients had a standard pterional approach supplemented by an orbital osteotomy. In the 7-year period 367 patients underwent treatment for their aneurysms (169 clipped and 198 coiled). Of the 169 patients who were operated on, 29 had a skull base approach, of which 25 were cranio-orbital. The aneurysm location was as follows: 16 middle cerebral artery (MCA), three carotid bifurcation, four anterior communicating artery (ACOMM), one ophthalmic and one basilar. There were no approach-related complications. The cranio-orbital craniotomy can be a useful adjunct in the surgical treatment of giant or complex aneurysms. It offers the following advantages over a standard pterional approach: reduces operative distance; allows easy splitting of the sylvian fissure; and provides a wide arc of exposure with multiple working corridors.




    Monitoring of median nerve somatosensory evoked potentials (SSEP) during surgery for a basilar artery aneurysm under moderate hypothermia revealed an unexpected loss of the first cortical peak. This was due to compression of the middle cerebral artery under the retractor during the surgical approach

  13. [Pseudomembranous colitis after surgery for a ruptured abdominal aortic aneurysm].

    Lozano Sánchez, F; Sánchez Fernández, J; Palacios, E; Fernández, M; Ingelmo Morin, A; Gómez Alonso, A


    We present a rare postoperative complication after surgical procedures for rupture of abdominal aortic aneurysms. The disease, a pseudomembranous colitis, was early recognized (by evidence of clostridium difficile after a coprocultive) and satisfactorily treated with vancomycin. From the literature review we found only a similar case but results were absolutely different from our case.

  14. Endovascular treatment of popliteal artery aneurysm. Early and midterm results

    Rodrigo Borges Domingues


    Full Text Available OBJECTIVE: to evaluate the efficacy of endovascular repair of popliteal artery aneurysms on maintaining patency of the stent in the short and medium term. METHODS: this was a retrospective, descriptive and analytical study, conducted at the Integrated Vascular Surgery Service at the Hospital da Beneficência Portuguesa de São Paulo. We followed-up 15 patients with popliteal aneurysm, totaling 18 limbs, treated with stent from May 2008 to December 2012. RESULTS: the mean follow-up was 14.8 months. During this period, 61.1% of the stents were patent. The average aneurysm diameter was 2.5cm, ranging from 1.1 to 4.5cm. The average length was 5cm, ranging from 1.5 to 10 cm. In eight cases (47.1%, the lesion crossed the joint line, and in four of these occlusion of the prosthesis occurred. In 66.7% of cases, treatment was elective and only 33.3% were symptomatic patients treated on an emergency basis. The stents used were Viabahn (Gore in 12 cases (66.7%, Fluency (Bard in three cases (16.7%, Multilayer (Cardiatis in two cases (11.1% and Hemobahn (Gore in one case (5.6%. In three cases, there was early occlusion (16.6%. During follow-up, 88.2% of patients maintained antiplatelet therapy. There was no leakage at ultrasound (endoleak. No fracture was observed in the stents. CONCLUSION: the results of this study are similar to other published series. Probably, with the development of new devices that support the mechanical characteristics found on the thighs, there will be improved performance and prognosis of endovascular restoration.

  15. Numerical predictions of hemodynamics following surgeries in cerebral aneurysms

    Rayz, Vitaliy; Lawton, Michael; Boussel, Loic; Leach, Joseph; Acevedo, Gabriel; Halbach, Van; Saloner, David


    Large cerebral aneurysms present a danger of rupture or brain compression. In some cases, clinicians may attempt to change the pathological hemodynamics in order to inhibit disease progression. This can be achieved by changing the vascular geometry with an open surgery or by deploying a stent-like flow diverter device. Patient-specific CFD models can help evaluate treatment options by predicting flow regions that are likely to become occupied by thrombus (clot) following the procedure. In this study, alternative flow scenarios were modeled for several patients who underwent surgical treatment. Patient-specific geometries and flow boundary conditions were obtained from magnetic resonance angiography and velocimetry data. The Navier-Stokes equations were solved with a finite volume solver Fluent. A porous media approach was used to model flow-diverter devices. The advection-diffusion equation was solved in order to simulate contrast agent transport and the results were used to evaluate flow residence time changes. Thrombus layering was predicted in regions characterized by reduced velocities and shear stresses as well as increased flow residence time. The simulations indicated surgical options that could result in occlusion of vital arteries with thrombus. Numerical results were compared to experimental and clinical MRI data. The results demonstrate that image-based CFD models may help improve the outcome of surgeries in cerebral aneurysms. acknowledge R01HL115267.

    YU Yang; GU Cheng-xiong; WEI Hua; LIU Rui; CHEN Chang-cheng; FANG Ying


    Background Acute myocardial infarction can result in left ventricular aneurysm, which may in turn cause congestive heart failure, ventricular arrhythmia and thromboembolic events. This study evaluates results achieved with a modified linear closure of left ventricular aneurysms during off-pump coronary artery bypass surgery.Methods From January 2001 to May 2004, 75 patients were operated on for nonruptured, postinfarctional, left ventricular aneurysm during off-pump coronary artery bypass surgery. Repair was completed on the beating heart to minimize ischaemia and allow assessment of wall function and viability to guide closure. All patients presented with symptoms of angina and congestive heart failure or ventricular arrhythmia. The majority (75%) of the patients were in NYHA functional class Ⅲ or Ⅳ. Preoperative ejection fraction was 26%±9%. The mean left ventricular, end diastolic diameter was (57.5±7.1) mm. The ventricular preoperative and postoperative performances were compared. χ2 test and Student's t test were used to analyse the outcomes. A P value less than 0.05 was considered significant.Results Hospital mortality was 1.3% (1/75). Coronary artery bypass was performed with an average of (3.3±1.2) grafts per patient. At the time of followup, all the patients had no symptoms. The mean NYHA class and ejection fraction increased significantly (P<0.001). The mean left ventricular, end diastolic diameter decreased significantly (P<0.001). Conclusions Surgical closure of left ventricular aneurysm can be performed during off-pump coronary artery bypass. The operation is associated with a low inhospital mortality and morbidity. A postoperative improvement in the early term cardiac functions and symptoms and quality of life was documented, increasing our expectations of an increased long-term survival.

  17. Successful use of Gamma Knife surgery in a distal lenticulostriate artery aneurysm intervention.

    Lan, ZhiGang; Li, Jin; You, Chao; Chen, Jing


    We report a case of a 21-year-old woman who underwent radiosurgical treatment of a distal lenticulostriate artery (LSA) aneurysm. Twenty-two months after treatment, repeat angiography demonstrated patency of the parent vessel and complete obliteration of the aneurysm. Our case implies that Gamma Knife surgery (GKS) might serve as an alternative microinvasive technique in the treatment of LSA aneurysms, making this procedure a potential addition to present methods.

  18. Surgery for aortic aneurysms: how to reduce tension on the anastomosis.

    Spinelli, Francesco; Benedetto, Filippo; Spinelli, Domenico; Stilo, Francesco; Lentini, Salvatore


    We describe a simple technique we use in our institution during surgery for aortic aneurysms to reduce tension on the anastomosis when there is a discrepancy between the remnant portion of the native aorta and the vascular prosthesis.

  19. [Early death in vascular surgery: an ongoing prognostic problem].

    Kazimierczak, Arkadiusz; Sledź, Marcin; Guzicka-Kazimierczak, Renata; Gutowski, Piotr; Cnotliwy, Miłosław


    Prediction of complications in surgery is commonly done. There are conflicting reports concerning the usefulness of risk scales (P-POSSUM, APACHE, SAPS, ASA, Goldman, etc.) in vascular surgery. We decided to take a fresh look at preoperative risk factors of early death in the context of the usefulness of some parameters which have not been included in existing risk calculators. The study group consisted of 1270 patients treated at the Department of Vascular Surgery, General Surgery, and Angiology, Pomeranian Medical University in Szczecin, during one year. METHOD This was a prospective non-randomized study. All data recorded at admission and data from P-POSSUM, ASA, Goldman, and ECOG-Zubroda-WHO scales were analyzed. Statistics were done with discriminant, multivariate, and logistic tests. There were 42 early deaths in the group. The following independent risk factors were involved in early death: ASA > 2 (OR = 18.31), persistent atrial fibrillation (OR = 5.75), leukocytosis (OR = 13.31), glomerular filtration rate (GFR) SIRS) (OR = 11.36), emergency admission (OR = 38.62), critical limb ischemia (OR = 4.87), acute limb ischemia (OR = 8,98), abdominal aortic aneurysm (OR = 4.4), and ruptured aortic aneurysm (OR = 10.59). Logistic regression exposed the influence of five factors: ASA III, ASA IV, persistent atrial fibrillation, leukocytosis, GFR surgery need to be "refreshed". Creation of the Polish National Vascular Surgery Register seems to be unavoidable.

  20. Augmented reality in the surgery of cerebral aneurysms: a technical report.

    Cabrilo, Ivan; Bijlenga, Philippe; Schaller, Karl


    Augmented reality is the overlay of computer-generated images on real-world structures. It has previously been used for image guidance during surgical procedures, but it has never been used in the surgery of cerebral aneurysms. To report our experience of cerebral aneurysm surgery aided by augmented reality. Twenty-eight patients with 39 unruptured aneurysms were operated on in a prospective manner with augmented reality. Preoperative 3-dimensional image data sets (angio-magnetic resonance imaging, angio-computed tomography, and 3-dimensional digital subtraction angiography) were used to create virtual segmentations of patients' vessels, aneurysms, aneurysm necks, skulls, and heads. These images were injected intraoperatively into the eyepiece of the operating microscope. An example case of an unruptured posterior communicating artery aneurysm clipping is illustrated in a video. The described operating procedure allowed continuous monitoring of the accuracy of patient registration with neuronavigation data and assisted in the performance of tailored surgical approaches and optimal clipping with minimized exposition. Augmented reality may add to the performance of a minimally invasive approach, although further studies need to be performed to evaluate whether certain groups of aneurysms are more likely to benefit from it. Further technological development is required to improve its user friendliness.

  1. Surgery of gigantic infrarenal aneurysm of abdominal aorta

    N. Rustempašić


    Full Text Available The case shows gigantic aneurysm of abdominal aorta, localized infrarenally, as well as aneurysms of bilateral iliac arteries, which were solved successfully by resection of aneurism of abdominal aorta, closure of iliac arteries near aortic bifurcation, and interposition of aorta-bifemural vascular graft. There were no postoperative complications,and final outcome was fully satisfactory.

  2. Use of indocyanine green videoangiography during intracranial aneurysm surgery reduces the incidence of postoperative ischaemic complications.

    Lai, Leon Tat; Morgan, Michael Kerin


    Microscope-integrated near-infrared indocyanine green videoangiography (ICGVA) has been shown to be a useful adjunct for intracranial aneurysm surgery. That the routine application of this technique reduces the risk of postoperative ischaemic complication, however, has not been reported. We present a retrospective matched-pair comparison of ICGVA guided aneurysm surgery versus historic control surgical cohort treated by the same author. Index patients and controls were matched for aneurysm size, location, patient demographics, risk factors, comorbidities, and surgical treatments. Ninety-one eligible patients with 100 intracranial aneurysms were treated using ICGVA assistance. There were no statistically significant differences between the two groups in terms of patient age, sex, risk factors, comorbidities and aneurysm characteristics. Of the 100 aneurysms in the ICGVA group, 107 investigations of ICGVA were performed. In 79 aneurysms (79.0%), ICGVA was considered useful but did not affect surgical management. In six patients (6.0%), ICGVA led to a crucial change of intraoperative strategies. In nine patients (9.0%), it was considered critical in assuring patency of small perforators. ICGVA was of no benefit in four patients (4.0%) and was misleading in two (2.0%). Postoperative ischaemic complications occurred in three patients (3.3%) in the ICGVA group compared with seven patients (7.7%) in the control group (paneurysm surgery as a safe and effective modality of intraoperative blood flow assessment. With all limitations of a retrospective matched-pair comparison, the use of ICGVA during routine aneurysm surgery reduces the incidence of postoperative ischaemic complications.

    Olsen, P S; Schroeder, T; Agerskov, Kim


    Between 1979 and 1988, 656 patients were operated upon for abdominal aortic aneurysm. Elective operation was performed in 287 patients (44%) and acute operation in 369 patients. A ruptured aneurysm was found in 218 patients (33%). Patients with arteriosclerotic heart disease, hypertension, impaired...... renal function or chronic pulmonary disease showed an increased perioperative mortality. Development of postoperative cardiac and renal complications could not be related to previous cardiac or renal diseases. The major postoperative complications were renal failure in 81 patients (12%), pulmonary...

  5. Surgery for left ventricular aneurysm after myocardial infarction:techniques selection and results assessment

    CHEN Xin; QIU Zhi-bing; XU Ming; LIU Le-le; JIANG Ying-shuo; WANG Li-ming


    Background The most appropriate surgical approach for patients with post-infarction left ventricular (LV) aneurysm remains undetermined.We compared the efficacy of the linear versus patch repair techniques,and investigated the mid-term changes of LV geometry and cardiac function,for repair of LV aneurysms.Methods We reviewed the records of 194 patients who had surgery for a post-infarction LV aneurysm between 1998 and 2010.Short-term and mid-term outcomes,including complications,cardiac function and mortality,were assessed.LV end-diastolic and systolic dimensions (LVEDD and LVESD),LV end-diastolic and end-systolic volume indexes (LVEDVI and LVESVI) and LV ejection fraction (LVEF) were measured on pre-operative and follow-up echocardiography.Results Overall in-hospital mortality was 4.12%,and major morbidity showed no significant differences between the two groups.Multivariate analysis identified preoperative left ventricular end diastolic pressure >20 mmHg,low cardiac output and aortic clamping time >2 hours as risk factors for early mortality.Follow-up revealed that LVEF improved from 37% pre-operation to 45% 12 months post-operation in the patch group (P=0.008),and from 44% pre-operation to 40% 12 months postoperation in the linear group (P=0.032).In contrast,the LVEDVI and LVESVI in the linear group were significantly reduced immediately after the operation,and increased again at follow-up.However,in the patch group,the LVEDVI and LVESVI were significantly reduced at follow-up.And there were significant differences in the correct value changes of LVEF and left ventricular remodeling between linear repair and patch groups.Conclusions Persistent reduction of LV dimensions after the patch repair procedure seems to be a procedure-related problem.The choice of the technique should be tailored on an individual basis and surgeon's preference.The patch remodeling technique results in a better LVEF improvement,further significant reductions in LV dimensions

  6. A Case of Unexpected Symptomatic Vasospasm after Clipping Surgery for an Unruptured Intracranial Aneurysm.

    Hashimoto, Hiroaki; Kameda, Masahiro; Yasuhara, Takao; Date, Isao


    Delayed symptomatic vasospasm after clipping surgery for unruptured aneurysm is rarely reported. We report a case of a 62-year-old woman who presented with symptomatic vasospasm 11 days after clipping surgery for an unruptured aneurysm. We could not predict the existence of vasospasm until ischemic symptoms developed. We retrospectively found mild vasospasm in the computed tomography angiogram taken 8 days after the operation. The patient complained of a prolonged unexpected headache 1 week after the operation. We should recognize prolonged unexpected headache as a warning sign of vasospasm.

  7. Early patency rate and fate of reattached intercostal arteries after repair of thoracoabdominal aortic aneurysms.

    Omura, Atsushi; Yamanaka, Katsuhiro; Miyahara, Shunsuke; Sakamoto, Toshihito; Inoue, Takeshi; Okada, Kenji; Okita, Yutaka


    The present study analyzes the early patency of intercostal artery reconstruction, using graft interposition and aortic patch anastomosis, and determines the fate of reattached intercostal arteries after repair of thoracoabdominal aortic aneurysms. We selected 115 patients (mean age, 63 ± 15 years; range, 19-83 years; male, n = 83) treated by thoracoabdominal aortic aneurysm repair with 1 or more reconstructed intercostal arteries at the Kobe University Graduate School of Medicine between October 1999 and December 2012. The intercostal arteries were reconstructed using graft interposition (n = 66), aortic patch anastomosis (n = 42), or both (n = 7). The hospital mortality rate was 7.8% (n = 9). Eleven patients (9.6%) developed spinal cord ischemic injury (permanent, n = 6, transient, n = 5). The average number of reconstructed intercostal arteries per patient was 3.0 ± 1.5 (1-7), and 345 intercostal arteries were reattached. The overall patency rate was 74.2% (256/345) and that of aortic patch anastomosis was significantly better than that of graft interposition (90.8% [109/120] vs 65.3% [147/225], P intercostal arteries became dilated in 2 patients. Aortic patch anastomosis might offer better patency rates and prevent spinal cord ischemic injury compared with graft interposition. Although aneurysmal changes in intercostal artery reconstructions are rare, large blocks of aortic wall reconstruction should be closely monitored.

    Pei-Hua Lu; Guo-Qing Tao; Wei Shen; Bin Cai; Zhi-Yang Jiang; Jian Sun


    The occurrence of concomitant aortic aneurysm and colorectal cancer is a rare medical entity, and controversy surrounds its optimal treatment. We report a case of rectal cancer and concomitant aneurysm from the ascending aorta to the common iliac artery. As with DeBakey type Ⅰ aortic dissecting aneurysm, our patient was treated by rectal cancer resection, with preservation of the anus (Dixon operation) under controlled hypotension. Blood pressure was maintained at 80-90/ 50-60 mmHg and the pulse at 70-90 beats/min. The pathological examination of the surgical specimen showed a poorly differentiated T3N0 tumor. The patient had an uneventful recovery without aneurysm rupture, and was discharged from hospital on postoperative day 15 after 3 d adjuvant chemotherapy with oxaliplatin combined with calcium folinate and fluorouracil. The patient was given six courses of adjuvant chemotherapy in 6 mo, without recurrence or metastasis, and the aneurysm was still stable after 2 years follow-up.

  9. Third ventriculostomy through the lamina terminalis for intracranial pressure monitoring after aneurysm surgery: technical note

    Kraemer Jorge L.


    Full Text Available OBJECTIVE: A new ventriculostomy technique through the lamina terminalis is described. This technique is applied mainly during aneurysm surgery at the acute stage. METHOD: Thirteen patients were operated on intracranial aneurysms and, during the procedure, had the lamina terminalis fenestrated. A ventricular catheter was inserted into the third ventricule, left in place and connected to an external drainage system for further intracranial pressure (ICP monitoring and/or cerebrospinal fluid (CSF drainage. RESULTS: ICP readings and CSF drainage were obtained in all cases. No complication was recorded. CONCLUSION: Third ventriculostomy through the lamina terminalis is a simple and easy technique that can be used as an alternative to conventional ventriculostomy. This procedure can be indicated in cases where the ventricule is not reached by means of another technique, and when the decision to perform ventriculostomy is made at the end of aneurysm surgery.

    Full Text Available Aim. To establish the risk factors for complications and fatal outcome after the operative occlusion of cerebral aneurysms. Methods. Retrospective study on 91 (lethality rate and on 72 operated patients (complications. For survived and dead patients, as well as for patients with and without complications, following parameters were compared: gender, age, clinical condition, preoperative interval, use of temporary clips, vasospasm, outcome, as well as localization, size and intraoperative rupture of the aneurysm. Results. Complications existed: in 54.5% of aneurysms of middle cerebral and 13.6% of aneurysms of internal carotid artery (p<0.01; in 18.2% of patients in the first and 45.8% of patients in the third clinical Hunt and Hess group (p<0.05; in 57.9% of patients with and 20.5% of patients without intraoperative rupture (p<0.01; in 50% of patients with and 18.7% of patients without vasospasm (p<0.05. Average aneurysmal size was 18 mm in group with complications and 10.8 mm in patients with no complications (p<0.05, while average preoperative intervals in these two groups were 20 and 8.7 days (p<0.05. Lethality rate was 25% for the third and 83.3% for the fourth and fifth clinical group (p<0.01, and the existence of complications significantly increased mortality (from 15.7% to 50%, p<0.01. Good outcome existed in 19.2% of operated patients with complications and in 78.3% of those without complications (p<0.01. Conclusions. Incidence of complications depended significantly on preoperative clinical condition, duration of preoperative interval, size, localization and intraoperative rupture of aneurysm. Complications significantly minimized the surgical treatment outcome and increased the lethality rate mortality.

  11. [Abdominal aortic aneurysm treated by endovascular surgery: a case report].

    Alconero-Camarero, Ana Rosa; Cobo-Sánchez, José Luis; Casaus-Pérez, María; García-Campo, María Elena; García-Zarrabeitia, María José; Calvo-Diez, Marta; Mirones-Valdeolivas, Luz Elena


    An aneurysm is an abnormal dilation or irreversible convex of a portion of an artery. The most common site of aneurysms is the abdominal aorta and their appearance is often due to degeneration of the arterial wall, associated with atherosclerosis and favored by risk factors such as smoking and hypertension, among others. Left untreated, aneurysm of the abdominal aorta usually leads to rupture. Treatment is surgical, consisting of the introduction of a prosthesis, composed basically of a stent and an introducer, into the aorta. We report the case of a person diagnosed with abdominal aortic aneurysm in a routine examination who was admitted for ambulatory surgical treatment. We designed a nursing care plan, following Virginia Henderson's conceptual model. The care plan was divided into 2 parts, a first preoperative phase and a second postimplantation or monitoring phase. The care plan contained the principal nursing diagnoses, based on the taxonomies of the North American Nursing Diagnosis Association (NANDA), nursing interventions classification (NIC) and nursing outcomes classifications (NOC), and collaboration problems/potential complications. The patient was discharged to home after contact was made with his reference nurse in the primary health center, since during the hospital phase, some NOC indicators remained unresolved.

    Tolva, Valerio Stefano; Bianchi, Paolo Guy; Cireni, Lea Valeria; Lombardo, Alma; Keller, Guido Carlo; Parati, Gianfranco; Casana, Renato Maria


    Endovascular surgery data are confirming the paramount role of modern endovascular tools for a safe and sure exclusion of thoracoabdominal lesions. A 57-year-old female presented with severe comorbidity affected by a 58 mm thoracoabdominal aortic aneurysm (TAAA). After patient-informed consent and local Ethical Committee and Italian Public Health Ministry authorization, three multilayer stents were implanted in the thoracoabdominal aortic tract, obtaining at a 20-month computed tomography scan follow up, a complete exclusion of the TAAA, with normal patency of visceral vessels. Multilayer stents can be used in thoracoabdominal aortic aneurysm, with positive results.

  14. Intraoperative monitoring by imaging and electrophysiological techniques during giant intracranial aneurysm surgery.

    Durand, A; Penchet, G; Thines, L


    Difficulties in giant intracranial aneurysm surgery are the consequence of aneurysmal wall histology and the complex angioarchitecture of the vascular tree. In order to reduce complications and risks of those procedures, various imaging and electrophysiological techniques can be implemented perioperatively. The authors review the principles, goals and main results in this context of micro-Doppler and flowmeter techniques, near-infrared spectroscopy, operative microscope-integrated indocyanine green video-angiography, neuro-endoscopy, selective intraoperative angiography and electrophysiological monitoring.

  15. Transient pupillary dilation following local papaverine application in intracranial aneurysm surgery.

    Zygourakis, Corinna C; Vasudeva, Viren; Lai, Pui Man Rosalind; Kim, Albert H; Wang, Huan; Du, Rose


    Isolated cases of transient pupillary changes after local intracisternal papaverine administration during aneurysm surgery have been reported. This study aimed to determine the prevalence and factors associated with this phenomenon. We assessed a total of 103 consecutive patients who underwent craniotomy for cerebral aneurysm clipping for the presence of postoperative pupillary dilation (mydriasis) after intracisternal papaverine administration. Univariate and multivariate logistic regression were conducted to evaluate the association of mydriasis with patient age, sex, duration of surgery, and aneurysm location. We observed either ipsilateral or bilateral pupillary dilation in the immediate postoperative period in nine out of 103 patients (8.7%). This phenomenon was not associated with patient age or sex. There was a trend towards positive correlation with aneurysms located at the anterior communicating artery (odds ratio 3.76, p=0.10), and a negative correlation with the duration of surgery (odds ratio 0.57, p=0.08). All pupillary dilation resolved within several hours, and the onset and resolution were consistent with the half-life of papaverine. To our knowledge, this represents the largest study of posteropative pupillary changes due to papaverine. The current findings are consistent with the small number of prior case reports of transient pupillary changes after papaverine administration and appear to reflect the local anesthetic action of papaverine on the oculomotor nerve.

  16. Incidental Finding of Intercostal Artery Aneurysm During Coarctation Surgery.

    Sabzi, Feridoun; Ghasemi, Fahime


    Intercostal artery aneurysms (ICAA) are very rare vascular complication of coarctation. The most cases are asymptomatic and could be found incidentally during thoracotomy for others vascular pathology or may present with fatal problems such as rupture that is leading to bleeding and hypovolemic shock. Intercostal artery aneurysm most commonly accompanies with neurofibromatosis, aortic coarctation, or in chest trauma. We report a 10-year-old girl who complained of lower extremities pain and hypertension for a few months. His final diagnosis was coarctation of the aorta. She was scheduled for thoracotomy and coarctation repair by resection and end to end anastomosis. During thoracotomy at lateral side of coarctation, an ICAA distal to coarctation site was seen that by a collateral artery connects to its upper intercostals artery. The patient was treated by ligation and resection of the affected intercostal artery and subsequent coarctation repair. The postoperative course was uneventful and, she was discharged on 7th postoperative day.

  17. Outcome of intracranial aneurysm surgery: single center experience

    Murat Ulutas


    Conclusion: Multiple aneurysms, poor grade and intracerebral hematomas are poor prognostic factors. The patients who have subarachnoid hemorrhage should be monitored by an experienced team of neurosurgery and intensive care and should be operated on as soon as possible because of rehemorrhage risk. The surgical clipping as a gold standard is still an affective and successful method. [Cukurova Med J 2016; 41(4.000: 732-743

  18. Essentials in intraoperative indocyanine green videoangiography assessment for intracranial aneurysm surgery: conclusions from 295 consecutively clipped aneurysms and review of the literature.

    Roessler, Karl; Krawagna, Maximilian; Dörfler, Arnd; Buchfelder, Michael; Ganslandt, Oliver


    Indocyanine green (ICG) videoangiography (VA) in cerebral aneurysm surgery allows confirmation of blood flow in parent, branching, and perforating vessels as well as assessment of remnant aneurysm parts after clip application. A retrospective analysis and review of the literature were conducted to determine the current essential advantages of ICG-VA in aneurysm surgery. The authors retrospectively evaluated all aneurysm cases treated with the aid of intraoperative ICG-VA at a single institution between 2007 and 2013. They also analyzed the literature published since the initial description of ICG-VA in 2003. Two hundred forty-six procedures were performed in 232 patients harboring 295 aneurysms. The patients, whose mean age was 54 years, consisted of 159 women and 73 men. One hundred twenty-four surgeries were performed after subarachnoid hemorrhage, and 122 were performed for incidental aneurysms. Single aneurysms were clipped in 185 patients, and multiple aneurysms were clipped in 47 (mean aneurysm diameter 6.9 mm, range 2-40 mm). No complications associated with ICG-VA occurred. Intraoperative microvascular Doppler ultrasonography was performed before ICG-VA in all patients, and postoperative digital subtraction angiography (DSA) studies were available in 121 patients (52.2%) for retrospective comparative analysis. In 22 (9%) of 246 procedures, the clip position was modified intraoperatively as a consequence of ICG-VA. Stenosis of the parent vessels (16 procedures) or occlusion of the perforators (6 procedures), not detected by micro-Doppler ultrasonography, were the most common problems demonstrated on ICG-VA. In another 11 procedures (4.5%), residual perfusion of the aneurysm was observed and one or more additional clips were applied. Vessel stenosis or a compromised perforating artery occurred independent of aneurysm location and was about equally common in middle cerebral artery and anterior communicating artery aneurysms. In 2 procedures (0.8%), aneurysm

  19. Results of clipping surgery for aneurysmal subarachnoid hemorrhage in the ninth and tenth decades of life.

    Horiuchi, Tetsuyoshi; Tsutsumi, Keiji; Ito, Kiyoshi; Hongo, Kazuhiro


    This study investigated the outcome of clipping surgery for ruptured aneurysms in patients older than 80 years of age. From 1988 to 2011 data were retrospectively reviewed, and 196 patients treated with clipping obliteration for aneurysmal subarachnoid hemorrhage were identified. Patients were divided into two age groups of 80-84 and ⩾ 85 years old. The Glasgow Outcome Scale score was assessed at discharge and classified as favorable (good recovery or moderate recovery) or unfavorable (severe disability, vegetative state, or dead). Radiological and clinical characteristics were compared between the two groups. A favorable outcome was achieved in 106 (54.1%) of the 196 patients. Preoperative grade and Fisher grade were significantly associated with unfavorable outcome, but age was not. Based on logistic regression analysis, poor preoperative grade and ruptured anterior cerebral artery aneurysm were the predictors of unfavorable outcome, but advanced age (⩾ 85 years old) was not. Advanced age itself did not affect the outcome of the elderly patients who underwent clipping surgery for aneurysmal subarachnoid hemorrhage.

  20. Risk control and prevention of spinal cord damage due to surgery of thoracoabdominal aneurysms: medicolegal aspects.

    de Mol, B; Hamerlijnck, R; Vermeulen, F E; de Geest, R


    Surgery of thoracoabdominal aneurysms is accompanied by many complications of which spinal cord damage is the most serious. Such a complication tends to be the subject of litigation and medicolegal assessment. This report presents a risk control concept focussed on the reduction of spinal cord damage after surgery for a thoracoabdominal aneurysm. This concept may provide a basis for a risk management program in major surgery. Apart from sparing the patient a serious complication, improvement of the quality of care and anticipation of a medicolegal assessment were considered valuable benefits of such an effort. It is described how the threat of litigation--also in Europe--may affect clinical practice. A definition of surgical failure is described related to the five elements of risk homeostasis: complexity, linkage, cascade, human factor and safety margins. Limitations of risk control in the surgery of thoracoabdominal aneurysms are described. Finally the role of perception of risks by patient and doctor as well as the importance of informed consent and adequate disclosure are described in respect of medical quality improvement and litigation.

    A 57-year-old male, previously treated surgically with insertion of grafts for type A and B aortic dissection, presented with a pulsatile mass in the jugular fossa. Further examination verified a pseudoaneurysm the inlet of which was located at the proximal anastomotic site of the descending aortic...... graft and a newly developed aneurysm of the aortic arch. Using a left lateral thoracotomy to avoid manipulation of the pseudoaneurysm, we adopted a hybrid approach by first debranching the subclavian and carotid arteries from the descending aorta followed by endoluminal grafting of the aortic arch...

    Objective To explore the therapeutic effect of preoperative external hunbar drainage in Hunt and Hess grade Ⅰ~Ⅲ patients with subarachnoid hemorrhage ( SAH ) undergoing early surgery for intracranial aneurysms. Method The 101 cases of grade Ⅰ~Ⅲ patients according to the classification of Hunt and Hess with early surgical treatment were devided into preoperative external lumbar drainage group(47 cases) and postoperative external lumbar drainage group(54 cases).Outcome of patients with different external drainage of cerebrospinal fluid was analyzed. Results There was no case of aneurysm rebleeding could be associated with preoperative spinal drain placement. Tne incidences of intraoperative aneurysm rapture in preoperative external lumbar drainage group was 8. 5%,which was lower than 11. 1% in postoperative external lumbar drainage group. The incidences of symptomatic cerebral vasospasm and chronic hydrocephalus in preoperative external lumbar drainage group were 12. 8% and 12.8% ,which were lower than 20. 4% and 14. 8% in postoperative external lumbar drainage group. There all were not significant differences between the two groups. Conclusions Preoperative external lumbar drainage wont increase a risk of rebleeding for grade Ⅰ~Ⅲ patients with aneurysmal SAH undergoing early surg ery. Furthermore, it can decrease the incidences of symptomatic cerebral vasospasm and chronic hydrocephalus,which is a safe and useful method of removing bloody cerebrospinal fluid.%目的 探讨Hunt-Hess Ⅰ~Ⅲ级动脉瘤性蛛网膜下腔出血(SAH)早期手术术前腰大池外引流的临床疗效.方法 将早期手术的Hunt-Hess Ⅰ~Ⅲ级动脉瘤性SAH患者分为术前腰大池外引流组(47例)和术后腰大池外引流组(54例),分析两组病例的疗效差异.结果 术前腰大池外引流组无置管导致的动脉瘤再破裂出血病例,其术中动脉瘤破裂、症状性脑血管痉挛、慢性脑积水的发生率分别为8.5%、12.8%、12

    Full Text Available Coarctation of aorta and sinus of Valsalva aneurysm are frequently missed congenital cardiac defects that their diagnosis might be delayed. To our knowledge, coincidence of these cardiac defects is unusual and has not been reported in the literature before. Here, we present a patient with coarctation of aorta and ruptured noncoronary sinus of Valsalva aneurysm leading to aorto-right atrial fistula in the early postpartum period and our management of this unusual case.

  5. Application of actuator-driven pulsed water jet in aneurysmal subarachnoid hemorrhage surgery: its effectiveness for dissection around ruptured aneurysmal walls and subarachnoid clot removal.

    Endo, Hidenori; Endo, Toshiki; Nakagawa, Atsuhiro; Fujimura, Miki; Tominaga, Teiji


    In clipping surgery for aneurysmal subarachnoid hemorrhage (aSAH), critical steps include clot removal and dissection of aneurysms without premature rupture or brain injuries. To pursue this goal, a piezo actuator-driven pulsed water jet (ADPJ) system was introduced in this study. This study included 42 patients, who suffered aSAH and underwent clipping surgery. Eleven patients underwent surgery with the assistance of the ADPJ system (ADPJ group). In the other 31 patients, surgery was performed without the ADPJ system (Control group). The ADPJ system was used for clot removal and aneurysmal dissection. The clinical impact of the ADPJ system was judged by comparing the rate of premature rupture, degree of clot removal, and clinical outcomes. Intraoperatively, a premature rupture was encountered in 18.2 and 25.8% of cases in the ADPJ and control groups, respectively. Although the differences were not statistically significant, intraoperative observation suggested that the ADPJ system was effective in clot removal and dissection of aneurysms in a safe manner. Computed tomography scans indicated the achievement of higher degrees of clot removal, especially when the ADPJ system was used for cases with preoperative clot volumes of more than 25 ml (p = 0.047, Mann-Whitney U test). Clinical outcomes, including incidence of postoperative brain injury or symptomatic vasospasm, were similar in both groups. We described our preliminary surgical results using the ADPJ system for aSAH. Although further study is needed, the ADPJ system was considered a safe and effective tool for clot removal and dissection of aneurysms.

  6. Battle of the Bulge: Aortic Aneurysm Management From Early Modernity to the Present.

    Barr, Justin


    For centuries, physicians have recognized aortic aneurysms as an acute threat to life. Therapeutic approaches to the disease began in the 18th century when leading physicians, such as René Laennec and Antonio Valsalva, applied research on circulation and blood coagulation to devise whole-body fasting and bleeding regimens to prevent rupture. After John Hunter's success in ligating arteries to treat peripheral aneurysms, surgeons attempted analogous operations on the aorta, but even the renowned Sir Astley Cooper and William Halsted met with disastrous results. Other clinicians tried various methods of creating intraluminal clots, including the application of such new technologies as electricity and plastic. Vessel repair techniques, pioneered by Alexis Carrel and others in the 20th century, eventually provided a reliably effective treatment. In the past few decades, minimally invasive methods that approach aneurysms endovascularly through small groin incisions have been adopted. A successful 2005 congressional campaign to fund screening for aortic aneurysms brought the disease to national attention and symbolizes current confidence in curing it. Drawing on various published and unpublished sources, this paper elucidates the development of specific treatments for aortic aneurysms over time and more broadly addresses how medicine and surgery apply the knowledge and technology available in particular eras to treat a specific, identifiable, and lethal disease. Examining the evolution of these therapeutic efforts unveils broader trends in the history of medicine. This allows aortic aneurysms to serve as a case study for exploring shifting philosophies in medical history.

  7. Video-assisted thoracic surgery for cancer after thoracic aortic aneurysm repair.

    Taylor, Lauren J; Adesoye, Taiwo; Maloney, James D


    Video-assisted thoracoscopic surgery is increasingly accepted as an alternative to open thoracotomy and has established efficacy in the management of non-small-cell lung cancer, but the presence of extensive intrapleural adhesions has been considered a deterrent to a minimally invasive approach. We report the successful use of video-assisted thoracoscopic surgery in 3 patients with history of open thoracic aortic aneurysm repair who presented with left lower lobe stage I non-small-cell lung cancer. While this approach is feasible, it is technically demanding and thus, at the present time, we recommend that its use be limited to high-volume video-assisted thoracoscopic surgery centers. © The Author(s) 2015.

  9. A Case Report of Coronary Arteriovenous Fistulas with an Unruptured Coronary Artery Aneurysm Successfully Treated by Surgery

    Nobuhiro Takeuchi


    Full Text Available A 58-year-old female with a history of Wolff-Parkinson-White syndrome presented at our institution with palpitations and chest pain. Electrocardiography revealed paroxysmal supraventricular tachycardia with a heart rate of 188 beats/min. Antiarrhythmic drugs were ineffective, and tachycardia was resolved by electrical cardioversion. Transthoracic echocardiography revealed abnormal vessels around the right coronary artery (RCA and pulmonary artery (PA; in addition, we suspected coronary arteriovenous fistula (CAVF. Coronary angiography and coronary computed tomography revealed dilated fistula vessels, with a 1 cm saccular aneurysm around the RCA, originating from the proximal RCA and left anterior descending artery into the main trunk of PA. Therefore, we confirmed the diagnosis of CAVF with an unruptured aneurysm. We surgically ligated and clipped the fistula vessels and resected the aneurysm. The resected aneurysm measured  cm in size. Pathological examination of the resected aneurysm revealed hypertrophic walls comprising proliferating fibroblasts cells thin elastic fibers. Very few atherosclerotic changes manifested in the aneurysm walls. We report the case of a patient with CAVF and an unruptured coronary artery aneurysm who was successfully treated by surgery.

  10. [Case of neuroleptic malignant syndrome following open heart surgery for thoracic aortic aneurysm with parkinson's disease].

    Shinoda, Maiko; Sakamoto, Mik; Shindo, Yuki; Ando, Yumi; Tateda, Takeshi


    An 80-year-old woman with Parkinson's disease was scheduled for open heart surgery to repair thoracic aortic aneurysm. Parkinson's symptoms were normally treated using oral levodopa (200 mg), selegiline-hydrochloride (5 mg), bromocriptine-mesilate (2 mg), and amantadine-hydrochloride (200 mg) daily. On the day before surgery, levodopa 50mg was infused intravenously. Another 25 mg of levodopa was infused immediately after surgery. Twenty hours later, the patient developed tremors, heyperventilation, but no obvious muscle rigidity. Two days after surgery, the patient exhibited high fever, hydropoiesis, elevated creatine kinase, and a rise in blood leukocytes. She was diagnosed with neuroleptic malignant syndrome. She was intubated, and received dantrolene sodium. Symptoms of neuroleptic malignant syndrome disappeared on the fourth postoperative day. The stress of open heart surgery, specifically extracorporeal circulation and concomitant dilution of levodopa, triggered neuroleptic malignant syndrome in this patient. Parkinson's patients require higher doses of levodopa prior to surgery to compensate and prevent neuroleptic malignant syndrome after surgery.

  14. Results of Castro Bernardes intraluminal ring in surgery for ascending aortic aneurysms and dissections

    Fernando Rotatori Novaes


    Full Text Available OBJECTIVE: To demonstrate surgical results using Castro Bernardes intraluminal ring in ascending aorta surgery, instead of conventional suture. METHODS: 95 patients underwent ascending aorta surgery from December 2008 to April 2011 at Madre Tereza Hospital (Belo Horizonte, MG, Brazil, using Castro Bernardes intraluminal ring instead of conventional suture of the aorta. RESULTS: Ninety five patients underwent ascending aorta surgery with Castro-Bernardes intraluminal ring. Thirty patients presented acute dissection and 65 aneurism. Overall postoperative mortality was 15.78% (15/95. Nine patients in 15 (60% died due to acute type A dissection. For acute type A dissection, mortality was 30% and for aneurism mortality was 9.23%. The intraluminal ring was inserted in distal position in 89 patients and in proximal and distal position in 6 patients. Mortality was related to Bentall & De Bono or Cabrol associated techniques. Average extracorporeal circulation time was 57.4 minutes and average aortic cross-clamping time was 37 minutes. CONCLUSION: The use of Castro Bernardes intraluminal ring in ascending aortic surgery avoiding conventional suture reduces extracorporeal circulation time and aortic cross-clamping time, improving surgical results. This approach simplifies ascending aortic surgery whether the disease is type A dissection or aneurysm, and may be considered a good alternative technique.

  15. [Patient with posterior reversible encephalopathy syndrome with prolonged disturbance of consciousness and convulsion after cerebral aneurysm surgery].

    Ueda, Kayo; Hoshi, Takuo; Yorozu, Shinko; Okazaki, Junko; Motomura, Yuji; Masumoto, Tomohiko; Tsubokawa, Tsunehisa; Tanaka, Makoto


    A 73-year-old patient developed convulsion and prolonged disturbance of consciousness after clipping surgery for unruptured cerebral aneurysm. The patient's consciousness improved four days after surgery, and radiological findings suggested posterior reversible encephalopathy syndrome (PRES). The cause of PRES is thought to be dysfunction of blood brain barrier by a sudden increase in blood pressure. In case of unexplained convulsion and decreased level of consciousness, PRES should be considered with radiographic examinations including CT and MRI.

  16. Smartphone as a Remote Touchpad to Facilitate Visualization of 3D Cerebral Angiograms during Aneurysm Surgery.

    Eftekhar, Behzad


    Background During aneurysm surgery, neurosurgeons may need to look at the cerebral angiograms again to better orient themselves to the aneurysm and also the surrounding vascular anatomy. Simplification of the intraoperative imaging review and reduction of the time interval between the view under the microscope and the angiogram review can theoretically improve orientation. Objective To describe the use of a smartphone as a remote touchpad to simplify intraoperative visualization of three-dimensional (3D) cerebral angiograms and reduce the time interval between the view under the microscope and the angiogram review. Methods Anonymized 3D angiograms of the patients in Virtual Reality Modelling Language format are securely uploaded to, accessible through smartphone Web browsers. A simple software has been developed and made available to facilitate the workflow. The smartphone is connected wirelessly to an external monitor using a Chromecast device and is used intraoperatively as a remote touchpad to view/rotate/zoom the 3D aneurysms angiograms on the external monitor. Results Implementation of the method is practical and helpful for the surgeon in certain cases. It also helps the operating staff, registrars, and students to orient themselves to the surgical anatomy. I present 10 of the uploaded angiograms published online. Conclusion The concept and method of using the smartphone as a remote touchpad to improve intraoperative visualization of 3D cerebral angiograms is described. The implementation is practical, using easily available hardware and software, in most neurosurgical centers worldwide. The method and concept have potential for further development.

    Choi, You Ri; Chang, Nam Kyu [Chonnam National University Hwasun Hospital, Hwasun (Korea, Republic of); Shin, Hyo Hyun; Oh, Hyun Jun; Kim, Jae Kyu; Choi, Soo Jin Na; Chung, Sang Young [Chonnam National University Hospital, Gwangju (Korea, Republic of); Yim, Nam Yeol [Armed Forces Yangju Hospital, Yangju (Korea, Republic of)


    To assess the outcomes of endovascular aortic aneurysm repair (EVAR) for the treatment of an abdominal aortic aneurysm in patients undergoing curative surgical treatment for concomitant abdominal malignancy. The study included 12 patients with abdominal neoplasia and an abdominal aortic aneurysm (AAA), which was treated by surgery and stent EVAR. The neoplasm consisted of the gastric, colorectal, pancreas, prostate, and gall bladder. The follow up period was 3-21 months (mean 11.8 months). All medical records and imaging analyses were reviewed by CTA and/or color Doppler US, retrospectively. Successful endoluminal repair was accomplished in all twelve patients. The mean interval time between EVAR and surgery was 58.6 days. Small amounts of type 2 endoleaks were detected in two patients (17%). One patient developed adult respiratory distress syndrome after Whipple's operation 20 days after surgery, which led to hopeless discharge. No procedure-related mortality, morbidity, or graft-related infection was noted. Exclusion of AAA in patients with accompanying malignancy show with a relatively low procedure morbidity and mortality. Hence, endoluminal AAA repair in patients with synchronous neoplasia may allow greater flexibility in the management of an offending malignancy

  18. Effect on management mortality of a deliberate policy of early operation on supratentorial aneurysms.

    Disney, L; Weir, B; Petruk, K


    Of 736 patients with intracranial aneurysms seen at the University of Alberta from 1968 to 1985, 437 were admitted on the day of or the day after subarachnoid hemorrhage (SAH) from a supratentorial aneurysm. Of these, 205 were managed from 1968 through 1977 and 232 were managed from 1978 through early 1985 after a policy of early aneurysm operation had been implemented. Postoperative and management mortality and morbidity rates were related to the grade of the patient at the time of admission and the time interval before operation. Overall management mortality (and postoperative mortality) rates for patients treated before 1978 were 47% (19%) for all grades, 17% (12%) for Grades 1 and 2, 51% (25%) for Grades 3 and 4, and 100% (100%) for Grade 5. Since 1978, mortality has been reduced to 38% (11%) for all grades, 10% (5%) for Grades 1 and 2, 39% (17%) for Grades 3 and 4, and 96% (60%) for Grade 5. Management mortality for patients operated on Day 0 to 3 was lower than for those operated later after SAH both before and after 1978. Postoperative mortality was lowered in all patients operated from 1978 to 1985 regardless of the interval from SAH to operation, and management mortality was reduced overall, as well as for patients operated on day 0 to 3, in those treated from 1978 to 1985. The authors conclude that a policy of early aneurysm operation has contributed to a reduction of both postoperative and management mortality.

  19. Fatal remote cerebellar hemorrhage after supratentorial unruptured aneurysm surgery in patient with previous cerebellar infarction

    Koh, Eun-Jeong; Park, Jung-Soo


    Abstract Rationale: Remote cerebellar hemorrhage (RCH) is a rare complication of supratentorial and spinal surgeries, seldom requiring intervention but occasionally causing significant morbidity or even mortality. Although a number of theories have been proposed, the exact pathophysiology of RCH remains incompletely understood. Patient concerns: We present a 62-year-old patient with RCH encountered following surgical clipping of an unruptured middle cerebral artery bifurcation aneurysm in a patient with previous cerebellar infarction. Lessons: It is extremely rare, but sometimes, RCH can be life-threatening. It is necessary to check the patient's general condition, underlying diseases and medical history. And controlled drainage of the CSF seems to be most important. Arachnoidplasty may be a consideration and the position of the drain string might have to be carefully determined. PMID:28121936

  20. [A patient with EDTA-dependent pseudothrombocytopenia who underwent emergent clipping surgery for a ruptured aneurysm].

    Yamaguchi, M; Mayumi, M; Kasuya, T


    A 42-year-old female with EDTA-dependent pseudothrombocytopenia underwent emergent clipping surgery for a ruptured aneurysm. On admission, the platelet count was low, but bleeding time and coagulation test were within normal limits. The blood smear anticoagulated with EDTA revealed remarkable agglutination of platelets, while heparinized blood showed a normal level. Diagnosis of EDTA-dependent pseudothrombocytopenia was made. The progressive drop in platelet count occurred within 10 minutes in the presence of EDTA. The autocounter misjudged the agglutination of platelets as red or white blood cells. The earlier study reported the incidence of this diseases as 0.07%. This disease is often misdiagnosed. Therefore, thrombocytopenia without any clinical symptom should be considered as showing a possible symptom of EDTA-dependent pseudothrombocytopenia.

  2. The role of intraoperative micro-Doppler ultrasound in verifying proper clip placement in intracranial aneurysm surgery.

    Siasios, Ioannis; Kapsalaki, Eftychia Z; Fountas, Kostas N


    Aneurysmal subarachnoid hemorrhage constitutes a clinical entity associated with high mortality and morbidity. It is widely accepted that improper clip placement may have as a result of incomplete aneurysm occlusion and/or partial or complete obstruction of an adjacent vessel. Various modalities, including intraoperative or postoperative digital subtracting angiography, near-infrared indocyanine green angiography, micro-Doppler ultrasonography (MDU), and neurophysiological studies, have been utilized for verifying proper clip placement. The aim of our study was to review the role of MDU during aneurysmal surgery. A literature search was performed using any possible combination of the following terms: "aneurysm," "brain," "cerebral," "clip," "clipping," "clip malpositioning," "clip repositioning," "clip suboptimal positioning," "Doppler," "intracranial," "microsurgery," "micro-Doppler," "residual neck," "ultrasonography," "ultrasound," and "vessel occlusion". Additionally, reference lists from the retrieved articles were reviewed for identifying any additional articles. Case reports and miniseries were excluded. A total of 19 series employing intraoperative MDU during aneurysmal microsurgery were retrieved. All studies demonstrated that MDU accuracy is extremely high. The highest reported false-positive rate of MDU was 2 %, while the false-negative rate was reported as high as 1.6 %. It has been demonstrated that the presence of subarachnoid hemorrhage, specific anatomic locations, and large size may predispose to improper clip placement. Intraoperative MDU's technical limitations and weaknesses are adequately identified, in order to minimize the possibility of any misinterpretations. Intraoperative MDU constitutes a safe, accurate, and low cost imaging modality for evaluating blood flow and for verifying proper clip placement during microsurgical clipping.

  3. Loss of visual evoked potential following temporary occlusion of the superior hypophyseal artery during aneurysm clip placement surgery. Case report.

    Goto, Tetsuya; Tanaka, Yuichiro; Kodama, Kunihiko; Kusano, Yoshikazu; Sakai, Keiichi; Hongo, Kazuhiro


    The authors report a case in which a 62-year-old woman with a history of subarachnoid hemorrhage due to a ruptured aneurysm was found to have a de novo paraclinoid aneurysm in the right internal carotid artery during a routine medical examination. Surgical clip placement was performed via a contralateral pterional approach under visual evoked potential (VEP) monitoring. The superior hypophyseal artery (SHA) was found to originate from the aneurysm body. The artery was temporarily occluded prior to application of the clip to the aneurysm neck. The VEP signal was lost 3 minutes after the SHA was occluded, and the potentials gradually recovered 10 minutes after the artery was released. The disappearance of VEP signal was reproducible with SHA occlusion. The clip was applied to the aneurysm body to preserve the origin of the SHA. The patient did not have any deterioration of vision after surgery. Intraoperative VEP monitoring can be used to help determine whether the SHA can be sacrificed safely.

  4. Early Experiences of Sandwich Technique to Preserve Pelvic Circulation during Endovascular Aneurysm Repair.

    Kim, Daehwan; Chung, Jung Kee; Park, Hyung Sub; Jung, In Mok; Lee, Taeseung


    To report experiences of the sandwich technique (ST) for preservation of pelvic flow during endovascular repair of complex aortic or aortoiliac aneurysms. Eight patients underwent elective endovascular aneurysm repair (EVAR) using the ST between March 2013 and February 2017. The anatomic indications for the ST were complex aortoiliac aneurysms (5 cases), abdominal aortic aneurysms (AAA) with non-diseased short common iliac arteries (2 cases) and AAA with unilateral occluded iliac artery (1 case). The ST was performed through both femoral and brachial approach. Patient clinical and radiologic data were collected and analyzed. Eight patients (7 male; mean age, 73.4 years) were followed over a mean period of 277 days (range, 9-1,106 days). The technical success rate was 100%. The primary patency rate of the iliac stent-grafts was 88% (14/16 cases). One internal iliac and 1 external iliac stent-graft occlusion was observed during the early postoperative period. There was 1 gutter endoleak which disappeared spontaneously within 4 days, and there were 2 type II endoleaks: one treated by coil embolization after 13 months, and the other observed without treatment. There were no cases of sac growth or aneurysm-related deaths, and no cases of buttock claudication or impotence. The ST is a safe and feasible technique to preserve pelvic circulation during endovascular treatment of complex aortoiliac aneurysms. The need to expand the indications for complex EVARs with adjunctive procedures, such as the ST is highlighted in situations where branched/fenestrated device availability is limited.

    AIM: To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm (AAA) repair surgery.METHODS: Nine patients (aged 35-78 years; body mass index (BMI) range: 23-36 kg/m2) post-surgery for AAA repair, and seven healthy control subjects (20-50 years;BMI range: 21-29 kg/m2) were studied. Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding (Nutrison(R)). Recordings were analyzed for the frequency,origin, length of migration, and direction of small intestinal burst activity. Lipid absorption was assessed on the first day and the third day post surgery in a subset of patients using the 13C-triolein-breath test, and compared with healthy controls. Subjects received a 20-min intraduodenal infusion of 50 mL liquid feed mixed with 200 μL 13C-triolein. End-expiratory breath samples were collected for 6 h and analyzed for 13CO2 concentration.RESULTS: The frequency of burst activity in the proximal and distal small intestine was higher in patients than in healthy subjects, under both fasting and fed conditions (P<0.005). In patients there was a higher proportion of abnormally propagated bursts (71% abnormal), which began to normalize by d 3 (25% abnormal) post-surgery.Lipid absorption data was available for seven patients on d 1 and four patients on d 3 post surgery. In patients,absorption on d 1 post-surgery was half that of healthy control subjects (AUC 13CO2 1323 ± 244 vs 2 646 ±365;P< 0.05, respectively), and was reduced to the one-fifth that of healthy controls by d 3 (AUC 13CO2 470 ± 832 vs 2646 ± 365; P< 0.05, respectively).CONCLUSION: Both proximal and distal small intestinal motor activity are transiently disrupted in critically ill patients immediately after major surgery,with abnormal motility patterns extending as far as the ileum. These motor disturbances may contribute to impaired absorption of enteral nutrition, especially when

Methods Eighty-two patients with ruptured anterior circulation aneurysms were analyzed retrospectively. They were divided into the low-grade group (grade Ⅰ to Ⅲ, n =64) and the high-grade group (grade Ⅳ to Ⅴ, n = 18) according to the Hunt & Hess scale on admission. Then they were also divided into early (≤3 d, n = 45), intermediate (4-10 d, n = 20) and late (≥11 d, n = 12) surgery groups according to their timing of surgery. Surgery were not performed in 5 patients for rebleeding. The outcome at 3 months was scored according to the Glasgow Outcome Scale (GOS). Results In the low-grade group, the rate of good outcome (GOS 4-5) in the early surgery group was significantly higher than that in the intermediate and late surgery groups (96. 3% vs. 75. 0%, P =0. 031), and the incidence of the major postoperative complications was significantly lower than that in the intermediate, and late surgery groups (22. 2% vs. 46. 9%, P =0. 049); the

  8. Flow diversion for complex intracranial aneurysms in young children.

    Navarro, Ramon; Brown, Benjamin L; Beier, Alexandra; Ranalli, Nathan; Aldana, Philipp; Hanel, Ricardo A


    Pediatric intracranial aneurysms are exceedingly rare and account for less than 5% of all intracranial aneurysms. Open surgery to treat such aneurysms has been shown to be more durable than endovascular techniques, and durability of treatment is particularly important in the pediatric population. Over the past 2 decades, however, a marked shift in aneurysm treatment from open surgery toward endovascular procedures has occurred for adults. The authors describe their early experience in treating 3 unruptured pediatric brain aneurysms using the Pipeline embolization device (PED). The first patient, a girl with Majewski osteodysplastic primordial dwarfism Type II who was harboring multiple intracranial aneurysms, underwent two flow diversion procedures for a vertebrobasilar aneurysm and a supraclinoid internal carotid artery aneurysm. The second patient underwent PED placement on a previously coiled but enlarging posterior communicating artery aneurysm. All procedures were uneventful, with no postsurgical complications, and led to complete angiographic obliteration of the aneurysms. To the authors' knowledge, this is the first series of flow diversion procedures in children reported in the medical literature. While flow diversion is a new and relatively untested technology in children, outcomes in adults have been promising. For challenging lesions in the pediatric population, flow diversion may have a valuable role as a well-tolerated, safe treatment with durable results. Many issues remain to be addressed, such as the durability of flow diverters over a very long follow-up and vessel response to growth in the presence of an endoluminal device.

  9. Surgical experience of the ruptured distal anterior cerebral artery aneurysms.

    Lee, Jong-Young; Kim, Moon-Kyu; Cho, Byung-Moon; Park, Se-Hyuck; Oh, Sae-Moon


    Distal anterior cerebral artery (DACA) aneurysms are fragile and known to have high risks for intraoperative premature rupture and a relatively high associated morbidity. To improve surgical outcomes of DACA aneurysms, we reviewed our surgical strategy and its results postoperatively. A total of 845 patients with ruptured cerebral aneurysms were operated in our hospital from January 1991 to December 2005. Twenty-three of 845 patients had ruptured DACA aneurysms which were operated on according to our surgical strategy. Our surgical strategy was as follows; early surgery, appropriate releasing of CSF, appropriate surgical approach, using neuronavigating system, securing the bridging veins, using temporary clipping and/or tentative clipping, meticulous manipulation of aneurysm, and using micro-Doppler flow probe. Twenty of 23 patients who had complete medical records were studied retrospectively. We observed the postoperative radiographic findings and checked Glasgow Outcome Scale score sixth months after the operation. Nineteen DACA aneurysms were clipped through a unilateral interhemispheric approach and one DACA aneurysm was clipped through a pterional approach. Postoperative radiographic findings revealed complete clipping of aneurysmal neck without stenosis or occlusion of parent arteries. In two patients, a residual neck of aneurysm was visualized. Seventeen patients showed good recovery, one patient resulted in moderate disability, while 2 patients died. With our surgical strategy it was possible to achieve acceptable surgical morbidity and mortality rates in patients with DACA aneurysms. Appropriate use of tentative clipping, temporary clipping and neuro-navigating systems can give great help for safe approach and clipping of DACA aneurysm.

  10. Combined extracranial-intracranial bypass surgery with stent-assisted coil embolization for moyamoya disease with a ruptured wide-necked basilar trunk aneurysm: a case report.

    Jiang, Hanqiang; Ni, Wei; Lei, Yu; Li, Yanjiang; Gu, Yuxiang


    A ruptured wide-necked basilar trunk aneurysm is uncommon in patients with moyamoya disease. The optimal treatment is unclear. We report a safe and beneficial treatment modality for moyamoya disease with aneurysms located in the posterior circulation. A 37-year-old man presenting with subarachnoid hemorrhage was admitted to our hospital. Emergent cerebral angiography demonstrated moyamoya disease associated with a wide-necked basilar trunk aneurysm. We performed bilateral extracranial-intracranial bypass surgeries prior to stent-assisted coil embolization of the aneurysm after the acute phase. No complication occurred and the patient was discharged with no neurological deficit. Follow-up digital subtraction angiography (DSA) performed 6 months after the surgery showed that all the anastomosises were patent and bilateral collateral vascular compensation was fully established with no recanalization of the basilar trunk aneurysm post embolization.We also found that high-flow bypass did not contribute to cerebral revascularization as imagined despite the good patency. Combined extracranial-intracranial bypass surgery with endovascular treatment proved to be an efficient therapeutic modality for moyamoya disease with aneurysms located in the posterior circulation. High-flow bypass surgery was not essential due to the inefficiency and the high risk of postoperative cerebral hyperperfusion syndrome.

  11. Effect of early mobilization and rehabilitation on complications in aneurysmal subarachnoid hemorrhage.

    Karic, Tanja; Røe, Cecilie; Nordenmark, Tonje Haug; Becker, Frank; Sorteberg, Wilhelm; Sorteberg, Angelika


    OBJECTIVE Early rehabilitation is effective in an array of acute neurological disorders but it is not established as part of treatment guidelines after aneurysmal subarachnoid hemorrhage (aSAH). This may in part be due to the fear of aggravating the development of cerebral vasospasm, which is the most feared complication of aSAH. The aim of this study was to evaluate the effect of early rehabilitation and mobilization on complications during the acute phase and within 90 days after aSAH. METHODS This was a prospective, interventional study that included patients with aSAH at the neuro-intermediate ward after aneurysm repair. The control group received standard treatment, whereas the early rehab group underwent early rehabilitation and mobilization in addition to standard treatment. Clinical and radiological characteristics of patients with aSAH, progression in mobilization, and treatment variables were registered. The frequency and severity of cerebral vasospasm, cerebral infarction acquired in conjunction with the aSAH, and acute and chronic hydrocephalus, as well as pulmonary and thromboembolic complications, were compared between the 2 groups. RESULTS Clinical and radiological characteristics of patients with aSAH were similar between the groups. The early rehab group was mobilized beginning on the first day after aneurysm repair. The significantly quicker and higher degree of mobilization in the early rehab group did not increase complications. Clinical cerebral vasospasm was not as frequent in the early rehab group and it also tended to be less severe. Each step of mobilization achieved during the first 4 days after aneurysm repair reduced the risk of severe vasospasm by 30%. Acute and chronic hydrocephalus were similar in both groups, but there was a tendency toward earlier shunt implantation among patients in the control group. Pulmonary infections, thromboembolic events, and death before discharge or within 90 days after the ictus were similar between the 2

  13. Direct Surgery of Previously Coiled Large Internal Carotid Ophthalmic Aneurysm for the Purpose of Optic Nerve Decompression

    Kawabata, Shuhei; Toyota, Shingo; Kumagai, Tetsuya; Goto, Tetsu; Mori, Kanji; Taki, Takuyu


    Background Progressive visual loss after coil embolization of a large internal carotid ophthalmic aneurysm has been widely reported. It is generally accepted that the primary strategy for this complication should be conservative, including steroid therapy; however, it is not well known as to what approach to take when the conservative therapy is not effective. Case Presentation We report a case of a 55-year-old female presenting with progressive visual loss after the coiling of a ruptured large internal carotid ophthalmic aneurysm. As the conservative therapy had not been effective, we performed neck clipping of the aneurysm with optic canal unroofing, anterior clinoidectomy, and partial removal of the embolized coils for the purpose of optic nerve decompression. After the surgery, the visual symptom was improved markedly. Conclusions It is suggested that direct surgery for the purpose of optic nerve decompression may be one of the options when conservative therapy is not effective for progressive visual disturbance after coil embolization.

    Pérez-Caballero Macarrón, C; Burgos Flores, J; Martos Sánchez, I; Pérez Palomino, A; Vázquez Martínez, J L; Alvarez Rojas, E; Fernández Pineda, L; Vellibre Vargas, D


    Several medical complications can occur after scoliosis surgery in children and adolescents. New surgical techniques have allowed greater degrees of scoliosis correction but have also increased the possibility of postsurgical deficit due to their greater aggressivity. We analyzed the early postsurgical complications of scoliosis surgery in a pediatric intensive care unit over a 10-year period. Seventy-six surgical procedures were performed. Of these, no complications occurred in 55 (73%). Chest X-ray revealed pulmonary atelectasia in 8 patients (10%) and pleural effusion in 7 patients (9%). Symptoms and signs of infection related to surgery were observed in only 6 children (8%). The absence of severe medical complications may be related to new surgical techniques and an experienced team.

  15. Usefulness of thin axial images of computerized tomography angiography for surgery on paraclinoid carotid artery aneurysms

    Nagasawa, Shiro; Deguchi, Jun; Arai, Motohiro; Tanaka, Hideo; Ohta, Tomio [Osaka Medical Coll., Takatsuki (Japan)


    Ten cases involving a total of 13 aneurysms located in the clinoid portion of the carotid artery were included in this study according to Al-Radham`s classification. Non-ionic, iodinated contrast solution, a total of 2 ml/ kg, was intravenously infused at a rate of 2 ml/sec. Helical scanning was begun 30 seconds after initiating the infusion, 1 mm pitch/1.5 second/rotation. 3-D images and original images of axial slices were compared to conventional angiography, DSA and surgical findings. The 3-D images of 3-D-CT-A were able to demonstrate both aneurysms located in the C2 segment of the carotid artery (groups I and II), and five of nine carotid cave aneurysms (group III). The aneurysms located more proximally (group IV or V) could not be visualized. Original axial images of 3-D-CT-A, on the other hand, clearly demonstrated the C2, C3 and C4 segment of the carotid artery, dome and neck of the aneurysm and bone structures such as the anterior clinoid process (ACP) and sella turcica in all cases. 3-D-CT-A is known to have several advantages in cases involving common locations around the Willis ring: multiple aneurysms on a single approach line, a giant aneurysm whose neck is not clearly demonstrated, or bony structures disturbing the access to aneurysms. However, it has been generally regarded that 3-D-CT-A is of little value for diagnosing paraclinoid internal carotid artery aneurysms. This study demonstrated that a series of original axial images of 3-D-CT-A provides excellent information regarding surgical anatomy; each segment of the carotid artery, neck and dome of the aneurysms, the ACP and its topographic relations to the aneurysm, calcification, and so forth. Since aneurysms can be visualized even in the presence of clips applied to adjacent aneurysms, original images are useful for the follow-up of these specific untreated aneurysms. (J.P.N.).

  16. Early extubation after congenital heart surgery

    Mirza Halimić


    Full Text Available Introduction: Despite recent advances in anesthesia, cardiopulmonary bypass and surgical techniques, children undergoing congenital heart surgery require postoperativemechanical ventilation. Early extubation was definedas ventilation shorter than 12 hours. Aim of this study is to identify factors associated with successful early extubation after pediatric cardiac surgery.Methods: The study was performed during period from January 2006 to January 2011 at Pediatric Clinic and Heart Center University Clinical center Sarajevo. One hundred children up to 5 years of age, who have had congenital heart disease, with left–right shunt and obstructive heart disease were included in the study. Patients were divided into two groups: Group I - patients extubated within 12 hours after surgery and Group II - patients extubated 12 or more hours after surgery. Results: The most frequently encountered preoperative variables were age with odds ratio 4% 95%CI (1-7%, Down's syndrome 8.5 95%CI (1.6-43.15, failure to thrive 4.3 95%CI( 1-18. Statistically significant postoperative data included lung disease (reactive airways, pneumonia, atelectasis, pneumothorax and with odds ratio 35.1 95 %CI (4-286 and blood transfusion with odds ratio 4.6 95%CI (2-12. Blood transfusion (p=0.002 (Wald=9.2 95%CI (2-12, during as well as after operation procedure has statistically significant influence on prediction time of extubation. Proven markers were age with cut of 21.5 months (sensitivity 74% and specificity 70% and extracorporeal circulation (ECC with cut-of 45.5 minutes (sensitivity 71% and specificity 65%.Conclusion: Early extubation is possible in many children undergoing congenital heart surgery. Younger age and prolonged ECC time are markers associated with prolonged mechanical ventilation.

    Murphy, Amanda; Bharatha, Aditya [University of Toronto, Department of Medical Imaging, Toronto, ON (Canada); De Oliveira Manoel, Airton Leonardo; Kouzmina, Ekaterina [St. Michael' s Hospital, Toronto (Canada); Burgers, Kyle; Lee, Ting [Robarts Research Institute, London (Canada); Macdonald, R.L. [St. Michael' s Hospital, Department of Neurosurgery, Toronto (Canada)


    Early brain injury (EBI) can occur within 72 h of aneurysmal subarachnoid hemorrhage (aSAH). The objective of this study was to determine if there are differences in early CTP parameters (<72 h) with respect to delayed cerebral ischemia (DCI), cerebral infarction, and functional outcome. We performed a prospective cohort study of aSAH patients admitted to a single tertiary care center. MTT, CBF and blood-brain barrier permeability (PS) were quantified with CTP within 72 h of aneurysm rupture. Primary outcomes were functional outcome by the Modified Rankin Scale (mRS) at 3 months and cerebral infarction. Secondary outcome was the development of DCI. Differences between early CTP parameters were determined with respect to primary and secondary outcomes. Fifty aSAH patients were included in the final analysis. MTT was significantly higher in patients who developed DCI (6.7 ± 1.2 vs 5.9 ± 1.0; p = 0.03) and cerebral infarction (7.0 ± 1.2 vs 5.9 ± 0.9; p = 0.007); however, no difference in MTT was found between patients with and without a poor outcome (mRS > 2). Early CBF and PS did not differ with respect to functional outcome, DCI, and cerebral infarction. Elevated MTT within 72 h of aneurysm rupture is associated with DCI and cerebral infarction but not with long-term functional outcome. Blood-brain barrier permeability, as assessed by CT perfusion, was not associated with DCI or worse outcome in this cohort. (orig.)

    Dayama, Anand; Sugano, Dordaneh; Reeves, James G; Rivera, Aksim; Tsilimparis, Nikolaos


    Open surgical repair of thoracoabdominal aortic aneurysms remains associated with significant morbidity and mortality. We sought to analyse multicentre national data on early outcomes of open surgical thoracoabdominal aortic aneurysm repair. Patients who underwent open repair of thoracoabdominal aortic aneurysm from 2005 to 2010 were identified from the National Surgical Quality Improvement Program database. The primary endpoint was mortality at 30 days. Patient demographics, clinical variables, and intraoperative parameters were analysed by univariate and multivariate logistic regression methods to identify risk factors for mortality. Of the 682 elective repairs, 30-day outcomes of elective repairs were: 10.0% mortality, 21.6% surgical complications, 42.2% pulmonary complications, 17.2% renal complications, 12.9% cardiovascular complications, 19.2% septic complications, and 6.6% wound complications. Multivariate logistic regression analysis showed that age, ASA-class IV, dependent functional status prior to surgery, and operation time are independent risk factors for mortality. Our study found a higher rate of mortality nationwide, as compared to several previous single center studies.

    Aneurysms are rare in children. Isolated iliac artery aneurysms are very rare, especially bilateral aneurysms. Pediatric aneurysms are usually secondary to connective tissue disorders, arteritis, or mycotic causes. We present a case of a 3-year-old child with bilateral idiopathic common iliac aneurysms that were successfully repaired with autogenous vein grafts. Copyright © 2013 Society for Vascular Surgery.

  20. Early endovascular treatment of aneurysmal subarachnoid hemorrhage complicated by neurogenic pulmonary edema and Takotsubo-like cardiomyopathy.

    Manto, Andrea; De Gennaro, Angela; Manzo, Gaetana; Serino, Antonietta; Quaranta, Gaetano; Cancella, Claudia


    Aneurysmal subarachnoid hemorrhage (SAH) may be associated with acute cardiopulmonary complications, like neurogenic pulmonary edema (NPE) and Takotsubo-like cardiomyopathy (TCM). These dysfunctions seem to result from a neurogenically induced overstimulation of the sympathetic nervous system through the brain-heart connection and often complicate poor grade aneurysmal SAH. The optimal treatment modality and timing of intervention in this clinical setting have not been established yet. Early endovascular therapy seems to be the fitting treatment in this particular group of patients, in which surgical clipping is often contraindicated due to the added risk of craniotomy. Herein we describe the case of a woman admitted to the emergency department with aneurysmal SAH complicated by NPE-TCM, in which early endovascular coiling was successfully performed. Our case, characterized by a favorable outcome, further supports the evidence that early endovascular treatment should be preferred in this peculiar clinical scenario.

  3. Laparoscopic surgery for early endometrial cancer.

    Bennich, Gitte; Rudnicki, Martin; Lassen, Pernille D


    The purpose of the present study was to evaluate learning curves and short-term outcomes following laparoscopic surgery for early endometrial cancer in women of different body mass index (BMI) classes. Data from 227 women planned for laparoscopic surgery for presumed stage I endometrial cancer were collected retrospectively from a Danish gynecologic oncology unit. Surgery included laparoscopic hysterectomy and bilateral salpingo-oophorectomy with or without pelvic lymphadenectomy (PLA). Median length of operations was 60 min (range, 30-197) and 120 min (range, 60-230), depending on whether PLA was included. The median pelvic lymph node yield was 18 (range, 7-42). For staging with PLA there was a learning curve when measured as operative time as well as lymph node yield, and a level of proficiency was not reached after 40 operations. The women had a perioperative complication rate of 4.5% and a median hospital stay of one night. Postoperative complication rate was 12%, comprising vaginal cuff hematoma (3.1%), vaginal cuff rupture (0.9%), trocar hernia (1.3%), ureter lesion (0.4%), bowel lesion (0.4%), reoperation (0.9%) and other complications (4.5%). All peri- and postoperative outcomes were independent of BMI classes. Our data suggest that laparoscopic surgery for early endometrial cancer is feasible and safe. With increasing surgeon's experience there is a significant decrease in operative time and increase in the number of lymph nodes harvested. In experienced hands, either operative time, complications or length of stay are not affected by increasing BMI, even when women are morbidly obese. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

  4. Cerebral Aneurysm Clipping Surgery Simulation Using Patient-Specific 3D Printing and Silicone Casting.

    Ryan, Justin R; Almefty, Kaith K; Nakaji, Peter; Frakes, David H


    Neurosurgery simulator development is growing as practitioners recognize the need for improved instructional and rehearsal platforms to improve procedural skills and patient care. In addition, changes in practice patterns have decreased the volume of specific cases, such as aneurysm clippings, which reduces the opportunity for operating room experience. The authors developed a hands-on, dimensionally accurate model for aneurysm clipping using patient-derived anatomic data and three-dimensional (3D) printing. Design of the model focused on reproducibility as well as adaptability to new patient geometry. A modular, reproducible, and patient-derived medical simulacrum was developed for medical learners to practice aneurysmal clipping procedures. Various forms of 3D printing were used to develop a geometrically accurate cranium and vascular tree featuring 9 patient-derived aneurysms. 3D printing in conjunction with elastomeric casting was leveraged to achieve a patient-derived brain model with tactile properties not yet available from commercial 3D printing technology. An educational pilot study was performed to gauge simulation efficacy. Through the novel manufacturing process, a patient-derived simulacrum was developed for neurovascular surgical simulation. A follow-up qualitative study suggests potential to enhance current educational programs; assessments support the efficacy of the simulacrum. The proposed aneurysm clipping simulator has the potential to improve learning experiences in surgical environment. 3D printing and elastomeric casting can produce patient-derived models for a dynamic learning environment that add value to surgical training and preparation.

  5. Hybrid repair of a very late, post-aortic coarctation surgery thoracic aneurysm: a case report

    Tilea Ioan


    Full Text Available Abstract Introduction Local aneurysms after surgical repair of coarctation of the aorta occur mainly in patients surgically treated by Dacron patch plasty during adulthood. The management of these patients is always problematic, with frequent complications and increased mortality rates. Percutaneous stent-graft implantation avoids the need for surgical reintervention. Case presentation We report a case involving the hybrid treatment by stent-graft implantation and transposition of the left subclavian artery to the left common carotid artery of an aneurysmal dilatation of the thoracic aorta that occurred in a 64-year-old Caucasian man, operated on almost 40 years earlier with a Dacron patch plasty for aortic coarctation. Our patient presented to our facility for evaluation with back pain and shortness of breath after minimal physical effort. A physical examination revealed stony dullness to percussion of the left posterior thorax, with no other abnormalities. The results of chest radiography, followed by contrast-enhanced computed tomography and aortography, led to a diagnosis of giant aortic thoracic aneurysm. Successful treatment of the aneurysm was achieved by percutaneous stent-graft implantation combined with transposition of the left subclavian artery to the left common carotid artery. His post-procedural recovery was uneventful. Three months after the procedure, computed tomography showed complete thrombosis of the excluded aneurysm, without any clinical signs of left lower limb ischemia or new onset neurological abnormalities. Conclusions Our patient’s case illustrates the clinical outcomes of surgical interventions for aortic coarctation. However, the very late appearance of a local aneurysm is rather unusual. Management of such cases is always difficult. The decision-making should be multidisciplinary. A hybrid approach was considered the best solution for our patient.

  6. [Evaluation of the blood coagulation system after surgeries on abdominal aortic aneurysms].

    Basing on data of analysis of the hemostasis system state in the patients, suffering abdominal aorta aneurysm, a tendency for raising of postoperative soluble fibrin and D-dimer content in the blood plasm and reduction of these indices on the third day was noted. The abovementioned markers content depends on the aneurysm size, the fibrin deposits presence, the terms from clinical signs beginning to the certain therapy administration and anticoagulants application. Information about correlation between content of D-dimer and soluble fibrin in the treatment dynamics is important for determination of activation degree in the patients blood coagulation system and the thrombotic complications prognosis.

  8. Donor Selection in Flow Replacement Bypass Surgery for Cerebral Aneurysms: Quantitative Analysis of Long-term Native Donor Flow Sufficiency.

    Rustemi, Oriela; Amin-Hanjani, Sepideh; Shakur, Sophia F; Du, Xinjian; Charbel, Fady T


    Graft selection in extracranial-intracranial bypass surgery for cerebral aneurysms has traditionally been based on clinical impression and operator preference. However, decision making can be optimized with a donor selection algorithm based on intraoperative flow data. To present long-term follow-up and quantitative assessment of flow sufficiency for native donors selected in this manner. Patients with bypass for anterior circulation intracranial aneurysms using only a native donor (superficial temporal artery) selected on the basis of an intraoperative flow algorithm over a 10-year period were retrospectively studied. Intracranial hemispheric and bypass flows were assessed preoperatively and postoperatively when available with quantitative magnetic resonance angiography. Twenty-two patients with flow data were included (median aneurysm size, 22 mm). The intraoperative flow offer (cut flow) of the superficial temporal artery was sufficient in these cases relative to the flow demand in the sacrificed vessel (59 vs 28 mL/min) to warrant its use. Bypass flow averaged 81 mL/min postoperatively (n = 19). Bypass flows were highest in the immediate postoperative period but remained stable between the intermediate and final follow-up (40 vs 52 mL/min; P = .39; n = 8). Mean ipsilateral hemisphere flows were maintained after bypass (299 vs 335 mL/min; P = .42; n = 7), and remained stable over intermediate and long-term follow-up. Ipsilateral hemispheric flows remained similar to contralateral flows at all time points. Despite a relative reduction in bypass flow over time, hemispheric flows were maintained, indicating that simple native donors can carry sufficient flow for territory demand long term when an intraoperative flow-based algorithm is used for donor selection.

    GUO Hong-wei; CHANG Qian; YU Cun-tao; SUN Xiao-gang; QIAN Xiang-yang; HUSheng-shou


    Background Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly,and SVA with discrete membranous subaortic stenosis is even rarer.The aim of the study was to make sure the incidence of SVA with discrete membraneous subaortic stenosis in SVA and their surgical results.We retrospectively analyzed 234 patients receiving surgical repair of SVA and reported the incidence of ventricular septal defect,aortic regurgitation,and discrete membranous subaortic stenosis.We also reported seven cases of SVA combined with discrete membranous subaortic stenosis and their surgical results.Methods Between January 1999 and December 2009,seven patients of SVA with discrete membranous subaortic stenosis underwent surgical repair of SVA and resection of subaortic discrete membrane.There were six male and one female patients.The mean age was (33.71±13.25) years (range 16-52 years).Associated cardiovascular lesions were aortic regurgitation (n=7),ventricular septal defect (n=5),coarctation of aorta (n=1),bicuspid aortic valve (n=1),patent ductus arteriosus (n=1),and aortic valve stenosis (n=1).The aortic valve was replaced in four patients and valvuloplasty was done in three.The other co-existing anomalies were corrected at the same time.All the seven patients were followed up from 18 to 125 months (mean (63.14±39.54) months).Among 234 SVA patients who underwent surgical repair,the number of cases with coexisting ventricular septal defect,aortic regurgitation,and discrete membranous subaortic stenosis was 129,108,and 7,respectively.Results There was neither early death after operation nor late death during the follow-up period.All the seven patients were in the New York Heart Association (NYHA) functional classes Ⅰ and Ⅱ.There was no recurrence of discrete subaortic membrane during the follow-up period.The incidence of ventricular septal defect,aortic valve incompetence,and discrete membranous subaortic stenosis among 234 SVA patients was 55.13%,46.15%,and 2.99

  10. Real-time surgery simulation of intracranial aneurysm clipping with patient-specific geometries and haptic feedback

    Fenz, Wolfgang; Dirnberger, Johannes


    Providing suitable training for aspiring neurosurgeons is becoming more and more problematic. The increasing popularity of the endovascular treatment of intracranial aneurysms leads to a lack of simple surgical situations for clipping operations, leaving mainly the complex cases, which present even experienced surgeons with a challenge. To alleviate this situation, we have developed a training simulator with haptic interaction allowing trainees to practice virtual clipping surgeries on real patient-specific vessel geometries. By using specialized finite element (FEM) algorithms (fast finite element method, matrix condensation) combined with GPU acceleration, we can achieve the necessary frame rate for smooth real-time interaction with the detailed models needed for a realistic simulation of the vessel wall deformation caused by the clamping with surgical clips. Vessel wall geometries for typical training scenarios were obtained from 3D-reconstructed medical image data, while for the instruments (clipping forceps, various types of clips, suction tubes) we use models provided by manufacturer Aesculap AG. Collisions between vessel and instruments have to be continuously detected and transformed into corresponding boundary conditions and feedback forces, calculated using a contact plane method. After a training, the achieved result can be assessed based on various criteria, including a simulation of the residual blood flow into the aneurysm. Rigid models of the surgical access and surrounding brain tissue, plus coupling a real forceps to the haptic input device further increase the realism of the simulation.

  12. CT angiography with three-dimensional techniques for the early diagnosis of intracranial aneurysms. Comparison with intra-arterial DSA and the surgical findings

    Karamessini, Maria T.; Kagadis, George C.; Petsas, Theodore; Karnabatidis, Dimitrios; Konstantinou, Dimitrios; Sakellaropoulos, George C.; Nikiforidis, George C.; Siablis, Dimitrios E-mail:


    Introduction: Cerebral CT angiography (CTA) is an established method applied to both the detection and treatment planning of intracranial aneurysms. The aim of our study was to compare CTA and digital subtraction angiography (DSA) findings with the surgical results mainly in patients with acute SAH and to evaluate the clinical usefulness of CTA. Materials and methods: During the last 2 years, 82 consecutive patients were admitted under clinical symptoms and signs suggestive of harboring an intracranial aneurysm. CT angiography performed immediately afterwards the plain CT, while DSA was performed within the first 48 h of admission. All aneurysms detected were confirmed during surgery or endovascular embolization. Repeat DSA was performed in all patients having both the initial CTA and the DSA 15 days after the onset of symptoms negative. CT angiograms and conventional angiographies were studied by a consensus of two radiologists for each technique, who performed aneurysm detection, morphological features characterization and evaluation of the technique. Results: Surgical or/and endovascular treatment was performed in 45 patients and 53 aneurysms were confirmed. Using 3D-CT angiography, we detected 47 aneurysms in 42 patients. Conventional angiography depicted 43 aneurysms in 39 patients. The sensitivity of CTA for the detection of all aneurysms versus surgery was 88.7%, the specificity 100%, the positive predictive value (PPV) 100%, the negative predictive value (NPV) 80.7% and the accuracy 92.3%. Accordingly, the sensitivity of DSA was 87.8%, the specificity 98%, the PPV 97.7%, the NPV 89.1% and the accuracy 92.9%. Considering aneurysms {>=}3 mm, CTA showed a sensitivity ranging from 93.3 to 100%, equal to that of DSA. Conclusion: Cerebral CT angiography has an equal sensitivity to DSA in the detection of intracranial aneurysms >3 mm. It has also 100% detection rate in AcoA and MCA bifurcation aneurysms, while some locations, like posterior communicating artery

We report one case of Atypical Kawasaki Disease with Multiple giant coronary artery aneurysms despite early adequate treatment with IVIG and ASA.

  14. Sensitivity of a Clinical Decision Rule and Early Computed Tomography in Aneurysmal Subarachnoid Hemorrhage

    Dustin G. Mark


    Full Text Available Introduction: Application of a clinical decision rule for subarachnoid hemorrhage, in combination with cranial computed tomography (CT performed within six hours of ictus (early cranial CT, may be able to reasonably exclude a diagnosis of aneurysmal subarachnoid hemorrhage (aSAH. This study’s objective was to examine the sensitivity of both early cranial CT and a previously validated clinical decision rule among emergency department (ED patients with aSAH and a normal mental status. Methods: Patients were evaluated in the 21 EDs of an integrated health delivery system between January 2007 and June 2013. We identified by chart review a retrospective cohort of patients diagnosed with aSAH in the setting of a normal mental status and performance of early cranial CT. Variables comprising the SAH clinical decision rule (age >40, presence of neck pain or stiffness, headache onset with exertion, loss of consciousness at headache onset were abstracted from the chart and assessed for inter-rater reliability. Results: One hundred fifty-five patients with aSAH met study inclusion criteria. The sensitivity of early cranial CT was 95.5% (95% CI [90.9-98.2]. The sensitivity of the SAH clinical decision rule was also 95.5% (95% CI [90.9-98.2]. Since all false negative cases for each diagnostic modality were mutually independent, the combined use of both early cranial CT and the clinical decision rule improved sensitivity to 100% (95% CI [97.6-100.0]. Conclusion: Neither early cranial CT nor the SAH clinical decision rule demonstrated ideal sensitivity for aSAH in this retrospective cohort. However, the combination of both strategies might optimize sensitivity for this life-threatening disease.

  15. Emergent endovascular vs. open surgery repair for ruptured abdominal aortic aneurysms: a meta-analysis.

    Chuan Qin

    Full Text Available OBJECTIVES: To systematically review studies comparing peri-operative mortality and length of hospital stay in patients with ruptured abdominal aortic aneurysms (rAAAs who underwent endovascular aneurysm repair (EVAR to patients who underwent open surgical repair (OSR. METHODS: The Medline, Cochrane, EMBASE, and Google Scholar databases were searched until Apr 30, 2013 using keywords such as abdominal aortic aneurysm, emergent, emergency, rupture, leaking, acute, endovascular, stent, graft, and endoscopic. The primary outcome was peri-operative mortality and the secondary outcome was length of hospital stay. RESULTS: A total of 18 studies (2 randomized controlled trials, 5 prospective studies, and 11 retrospective studies with a total of 135,734 rAAA patients were included. rAAA patients who underwent EVAR had significantly lower peri-operative mortality compared to those who underwent OSR (overall OR = 0.62, 95% CI = 0.58 to 0.67, P<0.001. rAAA patients with EVAR also had a significantly shorter mean length of hospital stay compared to those with OSR (difference in mean length of stay ranged from -2.00 to -19.10 days, with the overall estimate being -5.25 days (95% CI = -9.23 to -1.26, P = 0.010. There was no publication bias and sensitivity analysis showed good reliability. CONCLUSIONS: EVAR confers significant benefits in terms of peri-operative mortality and length of hospital stay. There is a need for more randomized controlled trials to compare outcomes of EVAR and OSR for rAAA.

  16. Acute kidney injury after infrarenal abdominal aortic aneurysm surgery: a comparison of AKIN and RIFLE criteria for risk prediction.

    Bang, J-Y; Lee, J B; Yoon, Y; Seo, H-S; Song, J-G; Hwang, G S


    Although both Acute Kidney Injury Network (AKIN) and risk, injury, failure, loss, and end-stage (RIFLE) kidney disease criteria are frequently used to diagnose acute kidney injury (AKI), they have rarely been compared in the diagnosis of AKI in patients undergoing surgery for infrarenal abdominal aortic aneurysm (AAA). This study investigated the incidence of, and risk factors for, AKI, defined by AKIN and RIFLE criteria, and compared their ability to predict mortality after infrarenal AAA surgery. This study examined 444 patients who underwent infrarenal AAA surgery between January 1999 and December 2011. Risk factors for AKI were assessed by multivariable analyses, and the impact of AKI on overall mortality was assessed by a Cox's proportional hazard model with inverse probability of treatment weighting (IPTW). Net reclassification improvement (NRI) was used to assess the performance of AKIN and RIFLE criteria in predicting overall mortality. AKI based on AKIN and RIFLE criteria occurred in 82 (18.5%) and 55 (12.4%) patients, respectively. The independent risk factors for AKI were intraoperative red blood cell (RBC) transfusion and chronic kidney disease (CKD) by AKIN criteria, and age, intraoperative RBC transfusion, preoperative atrial fibrillation, and CKD by RIFLE criteria. After IPTW adjustment, AKI was related to 30 day mortality and overall mortality. NRI was 15.2% greater (P=0.04) for AKIN than for RIFLE criteria in assessing the risk of overall mortality. Although AKI defined by either AKIN or RIFLE criteria was associated with overall mortality, AKIN criteria showed better prediction of mortality in patients undergoing infrarenal AAA surgery. © The Author 2014.

  18. Early and late surgical site infections in ear surgery.

    Bastier, P L; Leroyer, C; Lashéras, A; Rogues, A-M; Darrouzet, V; Franco-Vidal, V


    A retroauricular approach is routinely used for treating chronic otitis media. The incidence of surgical site infections after ear surgery is around 10% in contaminated or dirty procedures. This observational prospective study describes surgical site infections after chronic otitis media surgery with the retroauricular approach and investigated their potential predictive factors. This observational prospective study included patients suffering from chronic otitis media and eligible for therapeutic surgery with a retroauricular approach. During follow-up, surgical site infections were defined as "early" if occurring within 30 days after surgery or as "late" if occurring thereafter. The data of 102 patients were analysed. Concerning early surgical site infections, four cases were diagnosed (3.9%) and a significant association was found with preoperative antibiotic therapy, wet ear at pre-operative examination, class III (contaminated) in the surgical wound classification, NNIS (National Nosocomial Infection Surveillance) index > 1, and oral post-operative antibiotic use. Seven late surgical site infections were diagnosed (7.1%) between 90 and 160 days after surgery and were significantly correlated to otorrhoea during the 6 months before surgery, surgery duration ≤60 minutes, canal wall down technique and use of fibrin glue. Surgical site infections after chronic otitis media surgery seem to be associated with factors related to the inflammatory state of the middle ear at the time of surgery in early infections and with chronic inflammation in late infections. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

  19. Pediatric nonaortic arterial aneurysms.

    Davis, Frank M; Eliason, Jonathan L; Ganesh, Santhi K; Blatt, Neal B; Stanley, James C; Coleman, Dawn M


    Pediatric arterial aneurysms are extremely uncommon. Indications for intervention remain poorly defined and treatments vary. The impetus for this study was to better define the contemporary surgical management of pediatric nonaortic arterial aneurysms. A retrospective analysis was conducted of 41 children with 61 aneurysms who underwent surgical treatment from 1983 to 2015 at the University of Michigan. Arteries affected included: renal (n = 26), femoral (n = 7), iliac (n = 7), superior mesenteric (n = 4), brachial (n = 3), carotid (n = 3), popliteal (n = 3), axillary (n = 2), celiac (n = 2), ulnar (n = 2), common hepatic (n = 1), and temporal (n = 1). Intracranial aneurysms and aortic aneurysms treated during the same time period were not included in this study. Primary outcomes analyzed were postoperative complications, mortality, and freedom from reintervention. The study included 27 boys and 14 girls, with a median age of 9.8 years (range, 2 months-18 years) and a weight of 31.0 kg (range, 3.8-71 kg). Multiple aneurysms existed in 14 children. Obvious factors that contributed to aneurysmal formation included: proximal juxta-aneurysmal stenoses (n = 14), trauma (n = 12), Kawasaki disease (n = 4), Ehlers-Danlos type IV syndrome (n = 1), and infection (n = 1). Preoperative diagnoses were established using arteriography (n = 23), magnetic resonance angiography (n = 6), computed tomographic arteriography (n = 5), or ultrasonography (n = 7), and confirmed during surgery. Indications for surgery included risk of expansion and rupture, potential thrombosis or embolization of aneurysmal thrombus, local soft tissue and nerve compression, and secondary hypertension in the case of renal artery aneurysms. Primary surgical techniques included: aneurysm resection with reanastomsis, reimplantation, or angioplastic closure (n = 16), interposition (n = 10) or bypass grafts (n = 2), ligation (n = 9), plication (n = 8), endovascular occlusion (n = 3), and nephrectomy (n = 4) in

    López Álvarez, A; Román Fernández, A; Vilanova Vázquez, V; Corujeira Rivera, M C; Areán González, I; Valiño Hortas, C


    We report the anesthetic management with total intravenous anesthesia of a 61-year-old male diagnosed with limb-girdle muscular dystrophy admitted for replacement of ascending aorta due to an aortic aneurysm. Limb-girdle muscular dystrophy belongs to a genetically heterogeneous group of muscular dystrophies involving shoulder and hip girdles. Although the risk of malignant hyperthermia does not seem to be increased in these patients compared with the general population, the exposure to inhaled anesthetics and succinylcholine should probably be avoided because these patients have a predisposition to hyperkalemia and rhabdomyolysis. We chose to use total intravenous anesthesia with propofol, remifentanil and muscle relaxants to reduce oxygen consumption, and later to reduce the doses of propofol and remifentanil. The combination of a carefully planned anesthetic strategy, anesthetic depth, and neuromuscular blockade monitoring is explained.

    In vivo measurement of blood velocity fields and flow descriptors remains challenging due to image artifacts and limited resolution of current imaging methods; however, in vivo imaging data can be used to inform and validate patient-specific computational fluid dynamics (CFD) models. Image-based CFD can be particularly useful for planning surgical interventions in complicated cases such as fusiform aneurysms of the basilar artery, where it is crucial to alter pathological hemodynamics while preserving flow to the distal vasculature. In this study, patient-specific CFD modeling was conducted for two basilar aneurysm patients considered for surgical treatment. In addition to velocity fields, transport of contrast agent was simulated for the preoperative and postoperative conditions using two approaches. The transport of a virtual contrast passively following the flow streamlines was simulated to predict post-surgical flow regions prone to thrombus deposition. In addition, the transport of a mixture of blood with an iodine-based contrast agent was modeled to compare and verify the CFD results with X-ray angiograms. The CFD-predicted patterns of contrast flow were qualitatively compared to in vivo X-ray angiograms acquired before and after the intervention. The results suggest that the mixture modeling approach, accounting for the flow rates and properties of the contrast injection, is in better agreement with the X-ray angiography data. The virtual contrast modeling assessed the residence time based on flow patterns unaffected by the injection procedure, which makes the virtual contrast modeling approach better suited for prediction of thrombus deposition, which is not limited to the peri-procedural state.

    Alfotih Gobran Taha Ahmed


    Full Text Available Background: Due to insufficient data in the literature, the optimal timing for surgical intervention for ruptured intracranial aneurysms is still controversial. Some practitioners advocate early surgery, but others not. It is important to identify other factors that can be used to predict poor prognosis in ruptured intracranial aneurysm patients. Objective: To determine the influence of timing of clipping surgery, and other factors on the outcomes of ruptured intracranial aneurysms in Hunt & Hess I~III grade patients. Method: We have performed a retrospective study involving 80 patients who were surgically treated for ruptured intracranial aneurysm between 2007 and 2012. The patient population consisted of 50(62.5% females and 30(37.5% males, with an age range of 12 to 75 years old, mean age 52.33 ± 10.63 years. We measured association between the Glasgow Outcome Scores and Sex, timing of clipping surgery, aneurysm location and pre-operative patient's neurological condition using famous Hunt and Hess grade system. Results: We did not find any correlation between the outcomes of ruptured intracranial aneurysm patients and timing (early, intermediate, late stage of clipping, sex, aneurysm location. Whereas there is a significant correlation between patients outcomes and pre-operative patient neurological condition (Hunt & Hess grade. Conclusion: Timing of Surgery (early, intermediate, late does not affect outcomes in low Hunt and Hess grade patients I~III. Whereas neurological condition (Hunt & Hess has strong impact on postoperative outcomes. Others factors like sex, Age, Aneurysm location have no effect on outcomes in ruptured intracranial aneurysms.

    Children with early surgery for congenital heart disease (CHD) are known to have impaired neurodevelopment; their performance on school-age achievement tests and their need for special education remains largely unexplored. The study aimed to determine predictors of academic achievement at school age and placement in special education services among early CHD surgery survivors. Children with CHD surgery at codes. Predictors for achieving proficiency in literacy and mathematics and the receipt of special education were determined. Two hundred fifty-six children who attended Arkansas public schools and who had surgery as infants were included; 77.7 % had either school-age achievement-test scores or special-education codes of mental retardation or multiple disabilities. Scores on achievement tests for these children were 7-13 % lower than those of Arkansas students (p < 0.01). They had an eightfold increase in receipt of special education due to multiple disabilities [odds ratio (OR) 10.66, 95 % confidence interval (CI) 4.23-22.35] or mental retardation (OR 4.96, 95 % CI 2.6-8.64). Surgery after the neonatal period was associated with decreased literacy proficiency, and cardiopulmonary bypass during the first surgery was associated with decreased mathematics proficiency. Children who had early CHD surgery were less proficient on standardized school assessments, and many received special education. This is concerning because achievement-test scores at school age are "real-world" predictors of long-term outcomes.

  8. Periprocedural safety of aneurysm embolization with the Medina Coil System: the early human experience.

    Turk, Aquilla S; Maia, Orlando; Ferreira, Christian Candido; Freitas, Diogo; Mocco, J; Hanel, Ricardo


    Intracranial saccular aneurysms, if untreated, carry a high risk of morbidity and mortality from intracranial bleeding. Embolization coils are the most common treatment. We describe the periprocedural safety and performance of the initial human experience with the next generation Medina Coil System. The Medina Coil System is a layered three-dimensional coil made from a radiopaque, shape set core wire, and shape memory alloy outer coil filaments. Nine aneurysms in five patients were selected for treatment with the Medina Coil System. Nine aneurysms in five patients, ranging from 5 to 17 mm in size in various locations, were treated with the Medina Coil System. No procedural or periprocedural complications were encountered. Procedure times, number of coils used to treat the aneurysm, and use of adjunctive devices were much less than anticipated if conventional coil technology had been used. The Medina Coil System is a next generation coil that combines all of the familiar and expected procedural safety and technique concepts associated with conventional coils. We found improved circumferential aneurysm filling, which may lead to improved long term outcomes, with fewer devices and faster operating times. Published by the BMJ Publishing Group Limited.

    Gemmete, Joseph J; Toma, Ahmed K; Davagnanam, Indran; Robertson, Fergus; Brew, Stefan


    Childhood intracranial aneurysms differ from those in the adult population in incidence and gender prevalence, cause, location, and clinical presentation. Endovascular treatment of pediatric aneurysms is the suggested approach because it offers both reconstructive and deconstructive techniques and a better clinical outcome compared with surgery; however, the long-term durability of endovascular treatment is still questionable, therefore long-term clinical and imaging follow-up is necessary. The clinical presentation, diagnosis, and treatment of intracranial aneurysms in children are discussed, and data from endovascular treatments are presented. Copyright © 2013 Elsevier Inc.

  10. Early hyponatraemia after pituitary surgery: cerebral salt-wasting syndrome.

    Guerrero, R; Pumar, A; Soto, A; Pomares, M A; Palma, S; Mangas, M A; Leal, A; Villamil, F


    Hyponatraemia is a common complication in patients undergoing neurosurgery. It can be caused either by the syndrome of inappropriate secretion of antidiuretic hormone or by the cerebral salt-wasting syndrome (CSWS). CSWS frequently occurs in patients suffering from subarachnoid haemorrhage and brain injury, but it is rare after pituitary tumour surgery. However, this diagnostic possibility should be considered as these disorders require specific treatment and have different prognoses. In this article, we present a case of acute and early hyponatraemia caused by CSWS after pituitary tumour surgery. We also revise the aetiology, mechanisms, differential diagnosis and treatment of hyponatraemia after pituitary surgery.

  11. Mycotic aneurysm in a turtle hunter: brief review and a case report

    Harsha Moole


    Full Text Available Salmonella-associated mycotic aneurysm is a rare, but dreaded, complication of salmonellosis. Immunocompromised and elderly populations are more susceptible to develop this extra-intestinal complication. Salmonella is spread via fecal–oral and vehicle-borne routes. Reptiles, especially small pet turtles, have been linked with an increased risk of Salmonella infection. Diagnosis of mycotic aneurysm is a challenge due to atypical presentations. Recently, widespread use of CT scan imaging to evaluate for unexplained abdominal pain and sepsis has led to early identification of mycotic aneurysms. Antibiotic therapy and surgical intervention are the cornerstones of management. Open surgery has been the gold standard of treatment but is associated with increased morbidity and mortality. A relatively new alternative to open surgery is endovascular aneurysm repair (EVAR. It is comparatively less invasive and is associated with reduced early morbidity and mortality in the setting of mycotic aneurysm. However, there is a risk of late infection. Here, we present a patient with Salmonella mycotic aneurysm initially treated conservatively with antibiotic therapy who later underwent successful interval EVAR with no complications to date. Also included is a brief review of Salmonella-associated mycotic aneurysms.

    Hyhlik-Dürr, A; Debus, S; Eckstein, H-H; Lang, W; Schmitz-Rixen, T; Böckler, D; Boeckler, D


    There are increasing numbers of elective surgeries not only for abdominal aortic aneurysm repair but also for emergencies because of ruptured aneurysms (rAAA). Mortality rates of rAAA up to 40-50% have remained unchanged for years. Because of the elevated incidence of complications in rAAA, the overall mortality is at least 80% and shows a dismal prognosis for this group of patients. With ultrasonography, a cost-efficient, technically simple and safe method with high sensitivity is available for detecting abdominal aortic aneurysms. On the basis on an electronic Medline literature search and evaluation of data from the "voluntary quality assurance for abdominal aortic aneurysms 2008" of the German Society of Vascular Surgery (Deutsche Gesellschaft für Gefäßchirurgie und Gefäßmedizin DGG), this review presents critical analysis of the efficacy and cost-efficiency of an ultrasound-based screening programme for the early detection of abdominal aortic aneurysms. In this systematic review of the literature on AAA screening, a description of epidemiology and current situation concerning AAA in Germany will be given. The evaluation of 4 randomised studies for ultrasonic AAA screening is discussed and the recommendations of the German Society of Vascular Surgery concerning screening for AAA are highlighted. © Georg Thieme Verlag Stuttgart ˙ New York.

    Objective To compare clinical curative effects of open surgery (OS) or endovascular repair (EVAR) for patients with abdominal aortic aneurysm (AAA) in China.Data sources We performed a comprehensive search of both English and Chinese literatures involving case studies on retrograde OS or EVAR of AAA in China from January 1976 to December 2010.Study selection According to the inclusion criteria,76 articles were finally analyzed to compare patient characteristics,clinical success,complications,and prognosis.Results We analyzed a total of 2862 patients with 1757 undergoing OS (OS group) and 1105 undergoing EVAR (EVAR group).There was no significant difference in the success rate of the procedures.Operative time,length of ICU stay,fasting time,duration of total postoperative stay,blood loss,and blood transfusion requirements during the procedure were significantly lower in the EVAR group.A 30-day follow up revealed more cardiac,renal,pulmonary,and visceral complications in the OS group (P<0.01).Low-limb ischemia,however,was more common in the EVAR group (P<0.05).The 30-day mortality rate,including aorta-related and non-aorta related mortality,was significantly lower in the EVAR group (P<0.01).In the follow-up period,there were more patients with occlusions of artificial vessel and late endoleak in the EVAR group (P<0.01).The overall late mortality rate was higher in the OS group (P <0.01),especially non-aorta-related late mortality and mortality during the fourth to the sixth year (P<0.01).Conclusions EVAR was safer and less invasive for AAA patients.Patients suffered fewer complications and recovered sooner.However,complications such as artificial vessel occlusion,low-limb ischemia,and endoleak were common in EVAR.Clinicians should carry out further research to solve these complications and improve the efficacy of EVAR.

    Background Left ventricular aneurysm (LVA) is one of the serious complications after acute myocardial infarction.We attempted to evaluate the preliminary efficacy of LVA repair combined with epicardial radiofrequency ablation for ventricular arrhythmia during off-pump coronary artery bypass grafting (OPCAB).Methods From June 2009 to April 2011,31 patients with LVA had angina symptoms and ventricular arrhythmia.In all patients,circular and cross-shaped radiofrequency epicardial ablations were performed using unipolar ablation pen along the border between the aneurysm wall and normal cardiac tissue and in the central zone of the aneurysms,followed by a linear placation of ventricular aneurysms on beating heart.Results All the patients showed complete recovery.The average number of grafted vessels was 2.7±1.3.Intraoperative examinations revealed that the ventricular arrhythmia was effectively controlled by radiofrequency ablation.All cases had been followed up for one year.Holter monitoring revealed a significant reduction in ventricular arrhythmias (P <0.05).Echocardiography showed significant increase in left ventricular ejection fraction (P <0.05) and decrease in left ventricular end-diastolic diameter (P <0.05).Conclusions For patients with ventricular aneurysm and preoperative malignant arrhythmia,aneurysm repair plus epicardial radiofrequency ablation in OPCAB was found to be an effective and feasible therapeutic technique.However,medium-to long-term therapeutic efficacy of this method remains to be determined by future studies and observations.

  15. Recurrent Rare Genomic Copy Number Variants and Bicuspid Aortic Valve Are Enriched in Early Onset Thoracic Aortic Aneurysms and Dissections.

    Prakash, Siddharth; Kuang, Shao-Qing; Regalado, Ellen; Guo, Dongchuan; Milewicz, Dianna


    Thoracic Aortic Aneurysms and Dissections (TAAD) are a major cause of death in the United States. The spectrum of TAAD ranges from genetic disorders, such as Marfan syndrome, to sporadic isolated disease of unknown cause. We hypothesized that genomic copy number variants (CNVs) contribute causally to early onset TAAD (ETAAD). We conducted a genome-wide SNP array analysis of ETAAD patients of European descent who were enrolled in the National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC). Genotyping was performed on the Illumina Omni-Express platform, using PennCNV, Nexus and CNVPartition for CNV detection. ETAAD patients (n = 108, 100% European American, 28% female, average age 20 years, 55% with bicuspid aortic valves) were compared to 7013 dbGAP controls without a history of vascular disease using downsampled Omni 2.5 data. For comparison, 805 sporadic TAAD patients with late onset aortic disease (STAAD cohort) and 192 affected probands from families with at least two affected relatives (FTAAD cohort) from our institution were screened for additional CNVs at these loci with SNP arrays. We identified 47 recurrent CNV regions in the ETAAD, FTAAD and STAAD groups that were absent or extremely rare in controls. Nine rare CNVs that were either very large (>1 Mb) or shared by ETAAD and STAAD or FTAAD patients were also identified. Four rare CNVs involved genes that cause arterial aneurysms when mutated. The largest and most prevalent of the recurrent CNVs were at Xq28 (two duplications and two deletions) and 17q25.1 (three duplications). The percentage of individuals harboring rare CNVs was significantly greater in the ETAAD cohort (32%) than in the FTAAD (23%) or STAAD (17%) cohorts. We identified multiple loci affected by rare CNVs in one-third of ETAAD patients, confirming the genetic heterogeneity of TAAD. Alterations of candidate genes at these loci may contribute to the pathogenesis of TAAD.

  17. Pediatric intracranial aneurysms.

    Tripathy, L N; Singh, S N


    The incidence of subarachnoid haemorrhage from intracranial aneurysms in the paediatric age group is extremely rare. Interestingly, occurrence of vasospasm has been reported to be less in comparison to the adults. Both coiling and clipping have been advocated in selected cases. Because of the thinness of the wall of the arteries, utmost care should be taken while handling these arteries during surgery. The overall results of surgery in children have been reported to be better than their adult counterparts. We present four such cases from our own experience. All these children were operated upon, where the solitary aneurysm in each case was clipped and all of them made a good recovery.

  18. The establishment of endovascular aneurysm coiling at a neurovascular unit: report of experience during early years.

    Norbäck, O; Gál, G; Johansson, M; Solander, S; Tovi, M; Persson, L; Ronne-Engström, E; Enblad, P


    The treatment of cerebral aneurysms is changing from surgical clipping to endovascular coiling (EVC) in many neurovascular centres. The aim of this study was to evaluate the technical results and clinical outcome at 6 months in a consecutive series of subarachnoid hemorrhage (SAH) patients treated with EVC, in a situation when the EVC had been established very rapidly as the first line of treatment at a neurovascular centre. The patient material comprised 239 SAH patients (155 women and 84 men, mean age 55 years, age range 16-81) allocated to EVC as the first line of treatment in the acute stage (within 3 weeks of rupture) between September 1996 and December 2000. Clinical grade on admission was Hunt & Hess (H&H) I and II in 42%, H&H III in 25% and H&H grade IV and V in 33% of the patients. The aneurysm was located in the anterior circulation in 82% of the cases. EVC was performed on days 0-3 in 77% of the cases. EVC of the target aneurysm was able to be completed in 222 patients (93%). Complete occlusion was achieved in 126 patients (53%). Procedural complications occurred in 39 patients (16%). Favourable clinical outcome was observed in 57%, severe disability in 28% and poor outcome in 14% of the patients. Favourable outcome was achieved in 77% of H&H I and II patients and in 43% of H&H III-V patients. The multivariate logistic regression analysis revealed that younger age, good neurological grade on admission, absence of intracerebral hematoma and intraventricular hematoma respectively, ICA-PcomA aneurysm location, later treatment and absence of complications were significant predictors of favourable outcome. After interventional training and installation of the X-ray system, the introduction and establishment of EVC at a neurovascular unit can be done in a short period of time and with favourable results. Future studies must concentrate on identifying factors of importance for the choice of interventional or surgical therapy. The results of this study indicate

  19. [Temporary occlusion in surgical management of intracranial aneurysm. Report of 54 cases].

    Samaha, E; Rizk, T; Nohra, G; Mohasseb, G; Okais, N


    Temporary arterial occlusion (TAO) is commonly used in the surgery of intracranial giant aneurysms. Its usefulness and safety in the surgical management of all cases of aneurysms remains to be proved. We report a series of 54 patients operated on for an intracranial aneurysm with the use of TAO. Among the 27 patients, admitted before the 4th day following post subarachnoid hemorrhage with I or II on WFNS score clinically, 24 had early aneurysm surgery. The size of the aneurysm was small in 16 cases, medium in 22, large in 13 and giant in 3 cases. The protocol proposed by Batjer in 1988 for large and giant aneurysms (etomidate, normotention and hypervolemia) was used without any electrophysiological monitoring. All patients underwent a post-operative cerebral CT scan to evaluate the incidence of a cerebral ischemia. Serial transcranial doppler was used to evaluate the severity of vasospasm. Clinical results were assessed using the GOS. TAO was elective in 51 patients and done after peroperative aneurysm rupture in 3 patients. The duration of TAO was less than 5 mn in 25 patients, between 5 and 10 min in 12, between 10 and 15 in 11, between 15 and 20 in 5 and more than 20 min in one patient. The last one developed a reversible neurological deficit secondary to ischemia attribuated to TAO. Intracranial aneurysm peroperative rupture was noted in 3 patients, clinical vasospam in 13 patients. These results allow us to recommend the routine use of TAO in the surgery of intracranial aneurysm. When application time is limited and cerebral protection used, TAO is safe. It decreases the risk of intraoperative rupture from a 18% rate in literature to 4.2% in our present experience and the risk of symptomatic vasospasm is not increased.

  20. Video-assisted thoracoscopic surgery lobectomy – early experience

    Robert Šimon


    Full Text Available Introduction: Video-assisted thoracoscopic surgery (VATS lobectomy is the anatomical resection of a whole lobe ofthe lung followed by removal of the lymph nodes from the mediastinum using a thoracoscope and an access incision(small thoracotomy ≤ 5 cm without using the rib spreader. Aim: To present the early experience with VATS lobectomy. Material and methods: Five patients were treated surgically using the VATS technique of anatomical lung resection atthe 2nd Department of Surgery, Pavol Jozef Šafárik University, University Hospital of L. Pasteur, Košice, (Slovak Republicwithin 12 months from 10.2008 to 10.2009. Lobectomy was performed in 4 patients and pneumonectomy in 1 patient. Results: The mean operating time was 120 min (range 80-170 min. Following lobectomy a drain was inserted into thepleural cavity in 4 cases, whereas there was no drainage after 1 pneumonectomy. Drains were removed 2-5 days afterthe surgery. Four patients suffered from lung carcinoma (1 squamous cell carcinoma, 3 adenocarcinomas; 1 patienthad chondroid hamartoma. Postoperative condition was good in all patients. There were no early complications andpatients were released home on the 6th postoperative day on average. Conclusions: The advantages of VATS lobectomy have been widely discussed. There is a consensus that in elderlypatients with non-small cell lung cancer VATS lobectomy accompanied by mediastinal lymphadenectomy reduces theincidence of complications after the surgery and patients recover faster.

    SHI Xiang-en


    Full Text Available Objective To retrospectively analyze effective methods for surgical management of posterior circulation aneurysms. Methods There were 42 patients with posterior circulation aneurysms [26 cases of basilar aneurysm (27 aneurysms, 16 cases of vertebral aneurysm (17 aneurysms]. There were 15 patients underwent bypass surgery [4 external carotid artery-P2 segment of posterior cerebral artery (ECA-P2, 2 internal carotid artery-P2 segment of posterior cerebral artery (ICA-P2, 2 internal maxillary artery-P2 segment of posterior cerebral artery (IMA-P2, 2 intracranial segment of vertebral artery-extracranial segment of vertebral artery, 5 occipital artery-posterior inferior cerebellar artery (OA-PICA] and 27 patients underwent simple surgical clipping. Results Activities of daily life of 37 patients recovered to normal (14 patients with aneurysm on the top of basilar artery, 3 with aneurysm on the trunk of basilar artery, 9 with vertebral aneurysm, 5 with posterior inferior cerebellar artery aneurysm, 4 with aneurysm on the junction of P1-P2 segment of posterior cerebral artery, 1 with superior cerebellar artery, and 1 with anterior inferior cerebellar aneurysm. None of them occurred operation-related neurological dysfunction. The recovery rate was 88.09% . Among the other patients, 1 with aneurysm on the top of basilar artery presented severe signs and symptoms of neurological defect and cannot take care of oneself, 2 patients (1 with aneurysm on the top of basilar artery, 1 with aneurysm on the trunk of basilar artery occurred brain stem hemorrhage after operation, and died at perioperative period, 2 with vertebral aneurysm relapsed and was cured after treatment. Conclusion Posterior circulation aneurysm which is not suitable for surgical clipping can be treated with intra? and extra?cranial vessel bypass. It may avoid the risk of surgical clipping of aneurysm.

  5. Twin middle cerebral artery with aneurysm: A variant of early bifurcation or a discrete entity

    Sushant Sahoo


    Full Text Available The middle cerebral artery (MCA usually bifurcates into a superior or frontal and inferior or temporal branch. However, it may have various branching pattern, and there may be additional arteries from the anterior circulation supplying its territory. The majority of them remain asymptomatic. Some cases may have aneurismal dilatation due to turbulent blood flow or the weak arterial wall. The surgical approach in these cases may be challenging due to complex anatomical pattern of MCA. In this report, we have described a distinct pattern of left MCA with an aneurysm which was not clear in computed tomography angiogram and further confirmed on digital subtraction angiography. The different anatomical patterns of MCA and their surgical implications have also been discussed.

    Background Oculomotor palsy is a common complication in patients with posterior communicating aneurysm.This study was conducted to investigate the postoperative recovery of patients with posterior communicating aneurysm complicated with oculomotor palsy and to analyze the factors influencing length of recovery.Methods From 2000 to 2006,148 patients with posterior communicating aneurysm were treated at our hospital,with 74 of them having concurrent unilateral oculomotor palsy.All of the patients underwent craniotomy after the diagnosis by means of whole-brain digital subtraction angiography (DSA).The patients were divided into two groups for observation of postoperative recovery during the follow-up period.Patients in group A were treated with simple pedicle clipping of the aneurysm while patients in group B were treated with pedicle clipping of the aneurysm and decompression of the oculomotor nerve.Results Of the 40 patients in group A.20 underwent surgery within 14 days and completely recovered from oculomotor palsy in 10-40 days.Fourteen patients underwent surgery within 14-30 days.of whom 12 completely recovered within 30-90 days and 2 cases recovered incompletely.The remaining six patients underwent surgery after more than 30 days:of these.four patients recovered completely and two recovered incompletely.Of the 34 cases in group B,15 underwent surgery within 14 days and completely recovered from oculomotor palsy in 10-40 days.Sixteen patients underwent surgery in 14-30 days.of whom 14 completely recovered in 30-90 days and 2 recovered incompletely.The remaining three patients underwent surgery after more than 30 days,of whom two patients recovered completely and one recovered incompletely.Conclusions Early diagnosis and surgical treatment of patients with unilateral oculomotor palsy induced by posterior communicating aneurysm are important to full postoperative recovery of the oculomotor nerve.No correlation was found,however,between decompression of the

  8. Conservative surgery and radiation for early-stage breast cancer.

    Fowble, B L; Orel, S G; Jardines, L


    In selected patients with early-stage breast cancer, conservative surgery and radiation represent an alternative equal to mastectomy in terms of local recurrence, distant metastasis, survival, and long-term complications. Patients with early-stage breast cancer who are candidates for conservative surgery and radiation include those whose primary tumor is less than 4 to 5 cm in size without evidence of gross multicentricity or diffuse microcalcifications. Patients with an extensive intraductal component may be appropriate candidates provided that margins of resection are negative. Young age is not a contraindication to the conservative treatment. A preexisting history of collagen vascular disease or prior mantle irradiation for Hodgkin's or non-Hodgkin's lymphoma represents a contraindication to conservative surgery and radiation because of the potential for severe complications. An additional contraindication is the pregnant woman in whom delivery cannot be accomplished before the initiation of radiation. Mammography is essential in the pretreatment evaluation and posttreatment follow-up of the conservatively treated patient. The goal of the pretreatment mammogram is to assess the extent of disease in the ipsilateral breast as well as to evaluate the contralateral breast. In patients who present with microcalcifications, a postbiopsy mammogram before radiation is essential to document complete removal of all malignant-appearing microcalcifications. Mammography is an essential part of the follow-up program in order to detect a recurrence in the treated breast as well as a cancer in the contralateral breast cancer. The optimal interval for follow-up mammography has not been determined, although programs employing mammography on a yearly basis after treatment have been associated with the detection of early recurrences and excellent survival after salvage mastectomy for these recurrences.

  9. Horizontal stent-assisted coil embolisation of wide-necked intracranial aneurysms with the Enterprise stent - a case series with early angiographic follow-up

    Siddiqui, Mohammed Aslam; Bhattacharya, Joti J.; Jenkins, Sarah [Institute of Neurological Sciences, Southern General Hospital, Department of Neuroradiology, Glasgow (United Kingdom); Lindsay, Kenneth W. [Institute of Neurological Sciences, Southern General Hospital, Department of Neurosurgery, Glasgow (United Kingdom)


    The purpose of the study is to describe our experience in eight cases of horizontal stenting across the circle of Willis in patients with terminal aneurysms. Eight patients were treated with horizontal stent placement and aneurysm coiling. All aneurysms had highly unfavourable dome to neck ratios. All patients were followed up with digital subtraction angiography at 3-12 months following treatment. The Enterprise stent was successfully deployed horizontally in vessels of less than 2-mm diameter with no stent occlusion. Neurological complications occurred in one patient. Immediate and follow-up angiographic results were encouraging with six stable occlusions at 6 months. There was one asymptomatic case of in-stent stenosis and one case of late organised in-stent thrombus. Horizontal deployment of the Enterprise stent to assist coil embolisation of wide-necked terminal aneurysms is feasible. This device can be navigated via relatively small communicating arteries, in cases with favourable anatomy. Early angiographic results were favourable; however, longer-term follow-up will be required. (orig.)

  12. Early follow-up after endovascular aneurysm repair: is the first postoperative computed tomographic angiography scan necessary?

    Oikonomou, Kyriakos; Ventin, Felipe C; Paraskevas, Kosmas I; Geisselsöder, Peter; Ritter, Wolfgang; Verhoeven, Eric L


    To examine whether initial postoperative computed tomographic angiography (CTA) is needed in all patients undergoing endovascular aneurysm repair (EVAR). A total of 105 consecutive patients underwent EVAR with standard infrarenal devices in our department between November 2009 and May 2011. Five patients were excluded due to severe renal insufficiency, leaving 100 (85 men; median age 73 years, range 46-91) eligible for prospective enrollment in a triple-modality early postoperative follow-up protocol [intraoperative completion angiography, postoperative duplex ultrasonography (DUS), and plain abdominal radiography). Findings were compared for sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) against the first postoperative CTA results for the detection of endoleaks or other signs of EVAR failure. There were 10 inconclusive DUS examinations. In the remaining 90 patients, DUS had 75.0% sensitivity, 95.4% specificity, 85.7% PPV, and 91.5% NPV for the detection of endoleaks. The intraoperative angiogram, DUS, and abdominal radiograph combined resulted in 87.5% sensitivity and 95.4% specificity, with a 65.6% PPV and 94.8% NPV for the detection of endoleaks. In 2 patients who required a reintervention for endoleak in the early postoperative period, both endoleaks were correctly detected by the triple-modality early postoperative follow-up protocol. An early follow-up protocol consisting of an intraoperative completion angiogram, DUS, and abdominal radiograph shows a high sensitivity and NPV for the detection of endoleaks and should detect early migration or kinking of the stent-graft. An initial postoperative CTA is not necessary for most patients undergoing EVAR and should be reserved for those individuals in whom the aforementioned modalities are inconclusive or show signs of endoleak or other EVAR failure.

  13. [Increased urinary sodium excretion in the early phase of aneurysmal subarachnoid hemorrhage as a predictor of cerebral salt wasting syndrome].

    Nakagawa, Ichiro; Kurokawa, Shinichiro; Takayama, Katsutoshi; Wada, Takeshi; Nakase, Hiroyuki


    Cerebral salt wasting syndrome (CSWS) in patients with aneurysmal subarachnoid hemorrhage (SAH) is considered to correlate with delayed ischemic neurological deficits (DIND) induced by cerebral vasospasm; however, its exact mechanism is still not well-known. The purpose of the present study is to evaluate the relationship between hyponatremia caused by CSWS and the increase of the urinary sodium excretion in early phase following SAH. Fifty-four patients with SAH were divided into 2 groups, normonatremia group and hyponatremia group which suffered hyponatremia after SAH. The hyponatremia group comprise 14 patients (26%) in whom the hyponatremia developed of the SAH. In this group, the serum level of sodium significantly decreased 7 days after SAH and then gradually normalised. Further, excretion of sodium in the urine tended to increase 3 days after SAH and significantly increased 7 days after SAH. In conclusion, the increased urinary sodium excretion in the early phase of SAH would serve as a predictive factor for CSWS after SAH. We consider that it is important to start sodium and fluid supplementation and inhibit natriuresis by fludrocortisone acetate administration before hyponatremia occurs in order to prevention delayed ischemic neurological deficits in SAH patients.

  14. Ascending aortic aneurysms. Review of 100 consecutive cases.

    Liddicoat, J E; Bekassy, S M; Rubio, P A; Noon, G P; DeBakey, M E


    Aneurysms of the ascending aorta, if undiagnosed or untreated, may result in left ventricular failure from aortic valvular insufficiency. Aortic rupture, dissection, or compression of adjacent vital structures may also occur. The application of refined cardiopulmonary bypass devices, prosthetic heart valves, and synthetic grafts now allows successful surgical management of this disorder. This report presents our current diagnostic methods, surgical techniques, and the early and late results of 100 consecutive patients undergoing surgical treatment of aneurysms of the ascending aorta. There were 72 males and 28 females, ranging in age from 25 to 72 (ave 51.2) years. All patients had angiographic studies to demonstrate precisely the location of the aneurysm and the presence or absence of aortic valvular insufficiency. Sixty-three patients required concomitant aortic valve replacement, and the remaining 37 patients had only aneurysm resection and replacement. Pathological studies revealed 69 aneurysms were atherosclerotic, 22 were secondary to cystic medial necrosis, with the remaining 9 considered to be possibly leutic in origin. Despite the magnitude of the surgery and the advanced ages of some of these patients, the overall operative and hospital mortality rates were 4% and 9%. Survival rates by actuarial representation in 82 patients at 2, 4, 6, and 8 years were 82.9%, 78%, 70%, and 69.5%, respectively.

  15. Early complications after laparoscopic gastric bypass surgery: results from the Scandinavian Obesity Surgery Registry.

    To identify risk factors for serious and specific early complications of laparoscopic gastric bypass surgery using a large national cohort of patients. Bariatric procedures are among the most common surgical procedures today. There is, however, still a need to identify preoperative and intraoperative risk factors for serious complications. From the Scandinavian Obesity Surgery Registry database, we identified 26,173 patients undergoing primary laparoscopic gastric bypass operation for morbid obesity between May 1, 2007, and September 30, 2012. Follow-up on day 30 was 95.7%. Preoperative data and data from the operation were analyzed against serious postoperative complications and specific complications. The overall risk of serious postoperative complications was 3.4%. Age (adjusted P = 0.028), other additional operation [odds ratio (OR) = 1.50; confidence interval (CI): 1.04-2.18], intraoperative adverse event (OR = 2.63; 1.89-3.66), and conversion to open surgery (OR = 4.12; CI: 2.47-6.89) were all risk factors for serious postoperative complications. Annual hospital volume affected the rate of serious postoperative complications. If the hospital was in a learning curve at the time of the operation, the risk for serious postoperative complications was higher (OR = 1.45; CI: 1.22-1.71). The 90-day mortality rate was 0.04%. Intraoperative adverse events and conversion to open surgery are the strongest risk factors for serious complications after laparoscopic gastric bypass surgery. Annual operative volume and total institutional experience are important for the outcome. Patient related factors, in particular age, also increased the risk but to a lesser extent.

  16. Gender differences in abdominal aortic aneurysms.

    Hannawa, Kevin K; Eliason, Jonathan L; Upchurch, Gilbert R


    Abdominal aortic aneurysms (AAAs) comprise the tenth leading cause of death in Caucasian males 65 to 74 years of age and accounted for nearly 16,000 deaths overall in 2000. Therefore, understanding the pathophysiology of AAAs is an important undertaking. Clinically, multiple risk factors are associated with the development of AAAs, including increasing age, positive smoking history, and hypertension. Male gender is also a well-established risk factor for the development of an AAA, with a 4:1 male to female ratio. The reason for this gender disparity is unknown. The pathogenesis of AAAs formation is complex and multifactorial. Histologically, AAAs are characterized by early chemokine-driven leukocyte infiltration into the aortic wall. Subsequent destruction of elastin and collagen in the media and adventitia ensues owing to excessive local production of matrix-degrading enzymes and is accompanied by smooth muscle cell loss and thinning of the aortic wall. At present, no medical therapies are available to treat patients with aortic aneurysms, using only the crude measurement of aortic diameter as a threshold for which patients must undergo life-threatening and costly surgery. Defining the early mechanisms underlying gender-related differences in AAA formation is critical as understanding differences in disease patterns based on gender may allow us to develop new translational approaches to the prevention and treatment of patients with aortic aneurysms.

  17. [Ruptured aneurysm at the anterior wall of the internal carotid artery in a patient with systemic lupus erythematosus and secondary antiphospholipid syndrome].

    Chonan, Masashi; Fujimura, Miki; Inoue, Takashi; Tominaga, Teiji


    A 60 year-old woman, who had a 45-year history of systemic lupus erythematosus (SLE) and secondary antiphospholipid syndrome, presented with subarachnoid hemorrhage due to a ruptured aneurysm at the anterior wall of the non-branching site of the right internal carotid artery. She underwent radical surgery on the day of onset. In light of the possibility of arterial dissection, we performed extracranial-intracranial bypass prior to careful exploration of the aneurysm. Based on the finding of saccular aneurysm, she ultimately underwent neck clipping of the aneurysm without complication. Postoperative course was uneventful, and she did not suffer from cerebral vasospasm. We recommend early surgical intervention in patients with aneurysmal SAH associated with SLE, while intrinsic pathologies of SLE such as fragile vascular structure and the risk for ischemic complication should be considered.

  18. Early in vivo analysis of an endovascular stapler during endovascular aneurysm repair.

    Murphy, Erin H; Arko, Frank R


    The objective of this article is to describe the use and technique of a novel endostapling device used in an in vivo animal model. Six ovine underwent implantation of a Dacron endograft into the thoracic aorta followed by placement of endoclips proximally and distally. The animals were survived 35 days to evaluate the performance and safety of the endoclip in an animal model prior to clinical trials. The mean time for securing both the proximal and the distal anastomosis was 22 minutes (range 17-31 minutes). All staples were deployed, without the need for repositioning, on the first attempt. There were no complications related to the implant procedure or indwelling clips. Additionally, no endograft migration occurred. At the time of explant, staples were evaluated for depth of penetration and accuracy of placement. The staples had fully penetrated the endograft and vessel wall through the adventitia in 89% (64 of 72) of clips deployed. The staples were placed accurately, within 10 mm of the endograft proximal and distal attachments in 94% (68 of 72) of the clips deployed. Furthermore, endothelialization of the staples was present without surrounding thrombus. Implant sites were scored as normal without surrounding tissue damage by an independent pathologist. The endoclip performed well in creating proximal and distal fixation of the endograft. There were no adverse outcomes related to the endostaple. Future clinical trials should be undertaken to assess its clinical utility during endovascular aneurysm repair.

  19. [Inflammatory abdominal aortic aneurysm].

    Ziaja, K; Sedlak, L; Urbanek, T; Kostyra, J; Ludyga, T


    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

  20. Pulmonary artery aneurysm with patent arterial duct: resection of aneurysm and ductal division.

    Tefera, Endale; Teodori, Michael


    Congenital or acquired aneurysm of the pulmonary artery (PA) is rare. Although aneurysms are described following surgical treatment of patent ductus arteriosus (PDA), occurrence of this lesion in association with PDA without previous surgery is extremely uncommon. An eight-year-old patient with PDA and aneurysm of the main PA is described in this report. Clinical diagnosis of PDA was made upon presentation. Diagnosis of PA aneurysm was suspected on chest x-ray and was confirmed on transthoracic echocardiography. Successful surgical resection of the aneurysm and division of the duct were performed under cardiopulmonary bypass. The patient did well on follow-up both from clinical and echocardiographic point of view.

  1. Ultra-early Detection of Microcirculatory Injury as Predictor of Developing Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage.

    Gölitz, Philipp; Hoelter, Philip; Rösch, Julie; Roessler, Karl; Knossalla, Frauke; Doerfler, Arnd


    Delayed cerebral ischemia (DCI) still remains a major complication after subarachnoid hemorrhage (SAH). The aim of our study was to evaluate whether flow analysis of admission digital subtraction angiography (DSA) using parametric color coding (PCC), a postprocessing algorithm, allows ultra-early identification of SAH patients at risk for developing subsequent symptomatic vasospasm. In this study 52 patients who suffered SAH from aneurysm rupture, were retrospectively enrolled. Of the patients 26 developed DCI and angiographically proven cerebral vasospasm and 26 age, gender-and clinical status-matched SAH patients without DCI served as controls. Using PCC, the following flow parameters were calculated: cerebral circulation time (CirT), cortical relative time to peak (rTTP) and microvascular transit time (TT). Mean cerebral CirT and cortical rTTP were longer in the DCI group (6.42 s ± 1.54 and 3.16 s ± 0.86, respectively) than in the non-DCI group (5.77 s ± 1.86 and 3.11 s ± 1.41, respectively), but without statistical significance. The mean microvascular TT was statistically significantly (p = 0.04) longer in the DCI group (3.19 s ± 0.78) than in the non-DCI group (2.67 s ± 0.73). Angiographic flow analysis might be suitable for ultra-early detection and quantitative assessment of microcirculatory injury in SAH patients, predictive of developing subsequent DCI. Prolonged microvascular TT seems to be a significant independent factor positively associated with DCI development. Identifying SAH patients at risk for DCI ultra-early after ictus might contribute to initiate prophylactic therapies before clinical deterioration.

  2. Combined treatment for complex intracranial aneurysm

    Chiriac A.


    Full Text Available Complex aneurysms often cannot be completely excluded by a single approaches. Today successful treatment of these lesions requires a combination between microsurgical and endovascular techniques. Planning of combined treatment require a very good understanding of aneurysm anatomy and a close collaboration between neurosurgeon and neuroendovascular interventionist. Endovascular coiling can usually be used as early treatment for a partially aneurysm occlusion including the ruptured area and followed by definitive clipping. On the other hand microsurgical clipping also can be used as first treatment for complex aneurysm neck reconstruction, allowing successful secondary placement of coils inside the remnant aneurysm sac

  3. Limb salvage surgery for osteosarcoma- Early results in Indian patients

    Akshay Tiwari


    Full Text Available Background: While limb salvage surgery has long been established as the standard of care for osteosarcoma, large studies from Indian centers are few. Given the diverse socio economic milieu of our patients, it becomes significant to determine the feasibility and outcome of management of osteosarcoma in our population. We analyzed the early outcome of limb salvage surgery with multimodality treatment of osteosarcoma of the extremity/girdle bones at a tertiary North Indian Cancer Centre. Materials and Methods: A total of 51 limb salvage surgeries performed during the months between November 2008 and November 2012 were studied. Neoadjuvant/adjuvant chemotherapy was given by the pediatric/adult medical oncology teams as applicable. The mean followup was 19.45 months (range 2-50 months. The oncological outcome was correlated with age, sex, size of tumor, stage at presentation, site, histological subtype, type of chemotherapy protocol followed and necrosis seen on postoperative examination of resected specimen. The functional outcome of the patients was evaluated using the musculoskeletal tumor society (MSTS scoring system. Results: Out of a total of 37 males and 14 females with an average age of 18.8 years, the 3 year overall survival was 66% and 3 year event free survival was 61.8%. In this group of patients with a short followup, a better oncological outcome was associated with good postoperative tumor necrosis, nonchondroblastic histology and age <14 years. The average MSTS score was highest in patients with proximal or distal femur prosthesis and the lowest in patients undergoing a knee arthrodesis. Conclusion: The present study shows oncological and functional outcomes of limb salvage combined with chemotherapy in Indian patients with osteosarcoma comparable to those in world literature. Larger studies on Indian population with longer followup are recommended.

  4. Implantation of 3D-Printed Patient-Specific Aneurysm Models into Cadaveric Specimens: A New Training Paradigm to Allow for Improvements in Cerebrovascular Surgery and Research

    Arnau Benet


    Full Text Available Aim. To evaluate the feasibility of implanting 3D-printed brain aneurysm model in human cadavers and to assess their utility in neurosurgical research, complex case management/planning, and operative training. Methods. Two 3D-printed aneurysm models, basilar apex and middle cerebral artery, were generated and implanted in four cadaveric specimens. The aneurysms were implanted at the same anatomical region as the modeled patient. Pterional and orbitozygomatic approaches were done on each specimen. The aneurysm implant, manipulation capabilities, and surgical clipping were evaluated. Results. The 3D aneurysm models were successfully implanted to the cadaveric specimens’ arterial circulation in all cases. The features of the neck in terms of flexibility and its relationship with other arterial branches allowed for the practice of surgical maneuvering characteristic to aneurysm clipping. Furthermore, the relationship of the aneurysm dome with the surrounding structures allowed for better understanding of the aneurysmal local mass effect. Noticeably, all of these observations were done in a realistic environment provided by our customized embalming model for neurosurgical simulation. Conclusion. 3D aneurysms models implanted in cadaveric specimens may represent an untapped training method for replicating clip technique; for practicing certain approaches to aneurysms specific to a particular patient; and for improving neurosurgical research.

    The aim of this study is to evaluate computed tomography perfusion (CTP) during admission baseline period (days 0-3) in aneurysmal subarachnoid hemorrhage (A-SAH) for development of vasospasm. Retrospective analysis was performed on A-SAH patients from Dec 2004 to Feb 2007 with CTP on days 0-3. Cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) maps were analyzed for qualitative perfusion deficits. Quantitative analysis was performed using region-of-interest placement to obtain mean CTP values. Development of vasospasm was determined by a multistage hierarchical reference standard incorporating both imaging and clinical criteria. Student's t test and threshold analysis were performed. Seventy-five patients were included, 37% (28/75) were classified as vasospasm. Mean CTP values in vasospasm compared to no vasospasm groups were: CBF 31.90 ml/100 g/min vs. 39.88 ml/100 g/min (P < 0.05), MTT 7.12 s vs. 5.03 s (P < 0.01), and CBV 1.86 ml/100 g vs. 2.02 ml/100 g (P = 0.058). Fifteen patients had qualitative perfusion deficits with 73% (11/15) developed vasospasm. Optimal threshold for CBF is 24-25 mL/100 g/min with 91% specificity and 50% sensitivity, MTT is 5.5 s with 70% specificity and 61% sensitivity and CBV is 1.7 mL/100 g with 89% specificity and 36% sensitivity. These initial results support our hypothesis that A-SAH patients who develop vasospasm may demonstrate early alterations in cerebral perfusion, with statistically significant CBF reduction and MTT prolongation. Overall, CTP has high specificity for development of vasospasm. Future clinical implications include using CTP during the baseline period for early identification of A-SAH patients at high risk for vasospasm to prompt robust preventative measures and treatment.

  6. Thoracic aorta aneurysm repair in a patient with a solitary kidney: Hybrid Surgery as a bailout procedure

    Chris Bakoyiannis


    Full Text Available Thoracic endovascular aortic repair (TEVAR is an emerging treatment option for thoracic aorta aneurysms (TAA. Endovascular access is a challenge. We present a novel TEVAR-technique in a patient with single kidney and a 6.4cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid-TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft. Through the graft, a stent was introduced in the thoracic aorta. With the use of contrast material, the right position of the graft was confirmed.

  7. Intracranial aneurysms.

    Puskar, G; Ruggieri, P M


    MR angiography provides a rapid, accurate, and extremely flexible noninvasive evaluation of intracranial aneurysms without the cost and risk of conventional angiography. TOF and phase contrast techniques each have specific advantages and disadvantages that can be selectively exploited to optimize aneurysm evaluation. Present indications for MR angiography in aneurysm evaluation include: (1) the presence of incidental findings on a CT or MR examination that suggest the possibility of aneurysm (Figs. 7 and 8), (2) when angiography is contraindicated or when the risk is too high, (3) non-invasive follow-up of patients with known aneurysms, (4) patient refusal of contrast angiography, and (5) evaluation of patients with specific clinical symptoms (i.e., third cranial nerve palsy) or patients with non-specific subacute symptoms in whom an aneurysm might explain the clinical presentation. Although MR angiography certainly can detect aneurysms with a high rate of sensitivity and specificity, detailed decision analyses generally have not supported the overall benefit of this type of screening. Future technical advances as well as advances in the overall understanding of aneurysms may one day prove unequivocally the benefit of MR angiography in screening high-risk patient groups. MR angiography has not yet been clinically evaluated as a tool in the evaluation of acute subarachnoid hemorrhage. Potential obstacles to such an evaluation include the clinical instability of SAH patients, limited spatial resolution of the MR angiography acquisitions, the potential for subarachnoid blood or focal intraparenchymal hematomas to obscure or mimic small aneurysms, and the unreliability of MR angiography in demonstrating vasospasm. Currently these factors continue to provide an integral role for contrast angiography in aneurysm evaluation.

  8. EARLY COMPLICATIONS IN BARIATRIC SURGERY: incidence, diagnosis and treatment

    Marco Aurelio SANTO


    Full Text Available Context Bariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. Method The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery were reviewed. Ninety-three (17.2% patients were male and 445 (82.8% were female. The ages of the patients ranged from 18 to 70 years (average = 46, and their body mass indices ranged from 34.6 to 77 kg/m2. Results Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5% patients experienced pulmonary thromboembolism. The mortality rate was 0,55%. Conclusion The incidence of early complications was low. The diagnosis of these complications was mostly clinical, based on the presence of signs and symptoms. The value of the clinical signs and early treatment, specially in cases of sepsis, were essential to the favorable surgical outcome. The mortality was mainly related to thromboembolism and advanced age, over 65 years. Contexto A cirurgia bariátrica tem mostrado ser o método mais eficaz de tratamento da obesidade grave. No entanto, sua aceitação como terapia padrão-ouro ainda é questionada. As complicações cirúrgicas observadas no início do período p

    Ottlakan, Aurel; Martucci, Nicola; Rocco, Gaetano


    Under the formidable thrust of alternative management options for early stage lung cancer, the role of surgery in this disease subset has been questioned. Stereotactic body radiotherapy (SBRT) has been advocated as an ideal substitute for surgery not only in high risk patients or for the ones who refuse surgery but also in lieu of sublobar resection in otherwise fit patients. The therapeutic modalities for early stage NSCLC were compared as to warranting local control, enabling adequate tissu...

  13. Surgical management of recurrent intracranial aneurysms after embolization

    Hua-wei WANG


    Full Text Available Background Endovascular therapy is the first treatment choice for intracranial aneurysms currently, but it has a high recurrence rate. Some patients require surgical clipping because of the difficulty of re-embolization. This study retrospectively analyzed the clinical data of 11 cases who underwent clipping operation because of the recurrence after endovascular therapy. Combining with domestic and foreign related literatures, this paper discusses the principles and techniques of surgical treatment for recurrent aneurysms.  Methods There were a total of 11 patients with 12 recurrent aneurysms after embolization, including 3 anterior communicating artery (ACoA aneurysms, 3 middle cerebral artery (MCA aneurysms, 2 posterior communicating artery (PCoA aneurysms, one anterior cerebral artery (ACA aneurysm, one vertebral artery (VA aneurysm, one basilar tip aneurysm and one superior cerebellar artery (SCA aneurysm. There were 7 small aneurysms and 4 large aneurysms. All patients underwent surgical clipping under microscope. After operation, 11 aneurysms were complete clipped, and one was proximally blocked. The coils were reserved in 7 aneurysms, and were removed or partially removed in 5 aneurysms.  Results All patients were followed up for an average of 22 months after surgery. There were 9 cases (9/11 with the Glasgow Outcome Scale (GOS score improved or remaining unchanged compared with preoperation. One of them presented left limb weakness after operation, with the muscle strength Grade 3, while recovered to Grade 4-5 on discharge. The other 2 patients died after surgery. One case had a critical condition before surgery, and the other was secondary to thrombosis and pneumonia. Both of them had a GOS score of 2 when discharged, and died after discharge.  Conclusions There is high surgical difficulty in recurrent aneurysms, however, with adequate preoperative evaluation and surgical design, it can still promise safe and effective results

  14. Endovascular treatment of pediatric intracranial aneurysms: a retrospective study of 35 aneurysms.

    Takemoto, Koichiro; Tateshima, Satoshi; Golshan, Ali; Gonzalez, Nestor; Jahan, Reza; Duckwiler, Gary; Vinuela, Fernando


    Pediatric intracranial aneurysms are rare and not well characterized in comparison with those in adults. To analyze our institution's longitudinal experience of endovascular treatment for pediatric aneurysms to better understand this rare condition. A retrospective record review was performed of patients aged aneurysms between 1995 and 2012. There were 31 patients (average 14.4±4.2 years; 20 male, 11 female) with 35 intracranial aneurysms. The rate of subarachnoid hemorrhage as the initial presentation was 48% and the rates of multiple and giant aneurysms were 13% and 31%, respectively; 28.5% of the cases were posterior circulation aneurysms. Fifteen saccular aneurysms occurred in 14 patients and 17 fusiform aneurysms were noted in 14 patients. Two infectious aneurysms were diagnosed in two patients and one traumatic aneurysm occurred in another patient. Thirty-four aneurysms were treated endovascularly and one had thrombosed spontaneously on a follow-up angiogram. Of the 15 saccular aneurysms, 11 were treated with conventional coiling, one was treated with stent-assisted coiling, one was treated with a flow-diverting stent and two were treated with parent vessel occlusion (PVO). Of the 17 fusiform aneurysms, 15 were treated with PVO with or without prior bypass surgery and one was treated with a flow-diverting stent. The rate of permanent complications and a favorable outcome were 2.9% and 87%, respectively. Endovascular treatment of pediatric aneurysms is technically feasible with an acceptable complication rate despite the high incidence of fusiform aneurysms.

    Birendra Kumar Sah; Ming-Min Chen; Yi-Bing Peng; Xiao-Jing Feng; Min Yan; Bing-Ya Liu; Qi-Shi Fan; Zheng-Gang Zhu


    AIM: To investigate the role of sex hormones in the early postoperative complications of gastrointestinal diseases.METHODS: A total of 65 patients who underwent operations for gastric and colorectal diseases (mainly malignant diseases) were included in the study.Peripheral venous blood samples were collected at different times for analysis of estradiol, testosterone and progesterone. The only study endpoint was analysis of postoperative complications.RESULTS: Patients of both sexes were uniform but postoperative complication rate was significantly higher in female patients ( P = 0.027). There was no significant association of estradiol and progesterone with postoperative complications. Testosterone levels in complicated patients were significantly lower than in uncomplicated patients ( P < 0.05). Area under the receiver operating characteristic curve showed that a lower value of testosterone was a predictor for higher complication rate ( P < 0.05), and a lower value of testosterone at later times after surgery was a better predictor of complications.CONCLUSION: Patients with low testosterone level were prone to higher postoperative complications, which was evident in both sexes. However, further studies are necessary to support this result.

  16. Early-onset osteoarthritis, Charcot-Marie-Tooth like neuropathy, autoimmune features, multiple arterial aneurysms and dissections: an unrecognized and life threatening condition.

    Mélodie Aubart

    Full Text Available BACKGROUND: Severe osteoarthritis and thoracic aortic aneurysms have recently been associated with mutations in the SMAD3 gene, but the full clinical spectrum is incompletely defined. METHODS: All SMAD3 gene mutation carriers coming to our centre and their families were investigated prospectively with a structured panel including standardized clinical workup, blood tests, total body computed tomography, joint X-rays. Electroneuromyography was performed in selected cases. RESULTS: Thirty-four SMAD3 gene mutation carriers coming to our centre were identified and 16 relatives were considered affected because of aortic surgery or sudden death (total 50 subjects. Aortic disease was present in 72%, complicated with aortic dissection, surgery or sudden death in 56% at a mean age of 45 years. Aneurysm or tortuosity of the neck arteries was present in 78%, other arteries were affected in 44%, including dissection of coronary artery. Overall, 95% of mutation carriers displayed either aortic or extra-aortic arterial disease. Acrocyanosis was also present in the majority of patients. Osteoarticular manifestations were recorded in all patients. Joint involvement could be severe requiring surgery in young patients, of unusual localization such as tarsus or shoulder, or mimicking crystalline arthropathy with fibrocartilage calcifications. Sixty eight percent of patients displayed neurological symptoms, and 9 suffered peripheral neuropathy. Electroneuromyography revealed an axonal motor and sensory neuropathy in 3 different families, very evocative of type II Charcot-Marie-Tooth (CMT2 disease, although none had mutations in the known CMT2 genes. Autoimmune features including Sjogren's disease, rheumatoid arthritis, Hashimoto's disease, or isolated autoantibodies- were found in 36% of patients. INTERPRETATION: SMAD3 gene mutations are associated with aortic dilatation and osteoarthritis, but also autoimmunity and peripheral neuropathy which mimics type II

  17. Combined treatment for complex intracranial aneurysm

    Chiriac A.; Ion Georgiana; Dobrin N.; Iencean St.M.; Poeata I.


    Complex aneurysms often cannot be completely excluded by a single approaches. Today successful treatment of these lesions requires a combination between microsurgical and endovascular techniques. Planning of combined treatment require a very good understanding of aneurysm anatomy and a close collaboration between neurosurgeon and neuroendovascular interventionist. Endovascular coiling can usually be used as early treatment for a partially aneurysm occlusion including the ruptured area and fol...

  18. Can early computed tomography angiography after endovascular aortic aneurysm repair predict the need for reintervention in patients with type II endoleak?

    Dudeck, O; Schnapauff, D; Herzog, L; Löwenthal, D; Bulla, K; Bulla, B; Halloul, Z; Meyer, F; Pech, M; Gebauer, B; Ricke, J


    This study was designed to identify parameters on CT angiography (CTA) of type II endoleaks following endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA), which can be used to predict the subsequent need for reinterventions. We retrospectively identified 62 patients with type II endoleak who underwent early CTA in mean 3.7 ± 1.9 days after EVAR. On the basis of follow-up examinations (mean follow-up period 911 days; range, 373-1,987 days), patients were stratified into two groups: those who did (n = 18) and those who did not (n = 44) require reintervention. CTA characteristics, such as AAA, endoleak, as well as nidus dimensions, patency of the inferior mesenteric artery, number of aortic branch vessels, and the pattern of endoleak appearance, were recorded and correlated with the clinical outcome. Univariate and receiver operating characteristic curve regression analyses revealed significant differences between the two groups for the endoleak volume (surveillance group: 1391.6 ± 1427.9 mm(3); reintervention group: 3227.7 ± 2693.8 mm(3); cutoff value of 2,386 mm(3); p = 0.002), the endoleak diameter (13.6 ± 4.3 mm compared with 25.9 ± 9.6 mm; cutoff value of 19 mm; p < 0.0001), the number of aortic branch vessels (2.9 ± 1.2 compared with 4.2 ± 1.4 vessels; p = 0.001), as well as a "complex type" endoleak pattern (13.6 %, n = 6 compared with 44.4 %, n = 8; p = 0.02). Early CTA can predict the future need for reintervention in patients with type II endoleak. Therefore, treatment decision should be based not only on aneurysm enlargement alone but also on other imaging characteristics.

Methods Fifty-seven patients, admitted to our hospital from March 2007 to October 2009 and performed GIA clipping and/or resection, were chosen in this study. Intraoperative ICGA was performed using a surgical microscope with integrated ICGA technology before and after GIA clipping. The presence and patency of the parent artery and perforating artery around the aneurysms, and the information of aneurysm were analyzed in the mierosurgical field during surgical dissection and clip application. Assessment of vascular patency and occlusion of aneurysm after clipping was also investigated by DSA or CTA. These findings of ICGA were compared with those of postoperative DSA. Results A total of 128 investigations were performed in these 57 patients, and 61 aneurysms were clipped and removed. ICGA could provide real-time information about the circulation of the operating field and the patency of parent, branching and

  1. Current status of endovascular aneurysm repair: 20 years of learning.

    Arko, Frank R; Murphy, Erin H; Boyes, Christopher; Nussbaum, Tzvi; Lalka, Stephen G; Holleman, Jeremiah; Roush, Timothy S


    Parodi first introduced endovascular aneurysm repair (EVAR) in 1991 and since that time it has been shown to have a lower 30-day morbididty and mortality compared to open surgery. Anatomic constraints governed by the need for adequate access vessels, and sufficient proximal and distal landing zones, as well as the need for long-term surveillance, have been the main limitations of this technology. Anatomic factors were initially estimated to exclude 40% of patients with abdominal aortic aneurysm (AAA). The rapid extension of EVAR technology has been complimented by improved access to both high-quality imaging modalities and a variety of endografts. These developments have led EVAR to become a more practical alternative for patients with ruptured AAA. Early data in this setting is encouraging with even more profound reductions in morbidity and mortality than seen in the elective repair.

  2. Isolated iliac artery aneurysms with associated hydronephrosis.

    O'Driscoll, D


    An isolated iliac artery aneurysm is where there is aneurysmal dilatation of one or more branches of the iliac system, with no associated dilatation of the aorta. Such aneurysms are rare and comprise 1% of all intra-abdominal aneurysms. The signs and symptoms of such an aneurysm are influenced by its concealed location within the bony pelvis. Awareness of these special characteristics improves the chances of early diagnosis and proper treatment before possible rupture. We present the clinical and radiological features of three such aneurysms. Ultrasound was the first imaging modality to be performed. Ipsilateral hydronephrosis was demonstrated in each case, this lead to imaging the pelvis and the correct diagnosis. We review the clinical and radiological literature and conclude that the pelvis should be imaged in all cases of unexplained hydronephrosis.

  3. Early outcome of minimally invasive mitral valve surgery

    Shawky Fareed


    Conclusion: Right anterolateral mini-thoracotomy minimally invasive technique provides excellent exposure of the mitral valve, even with a small atrium and offers a better cosmetic lateral scar which is less prone to keloid formation. In addition, minimally invasive right anterolateral mini-thoracotomy is as safe as median sternotomy for mitral valve surgery, with fewer complications and postoperative pain, less ICU and hospital stay, fast recovery to work with no movement restriction after surgery. It should be used as an initial approach for mitral valve surgery. Furthermore, it was believed that less spreading of the incision, no interference with the diaphragm and less tissue dissection might improve outcomes, particularly respiratory function.

  4. In vivo imaging of macrophages during the early-stages of abdominal aortic aneurysm using high resolution MRI in ApoE mice.

    Yuyu Yao

    Full Text Available BACKGROUND: Angiotensin II (ANG II promotes vascular inflammation and induces abdominal aortic aneurysm (AAA in hyperlipidemic apolipoprotein E knock-out (apoE(-/- mice. The aim of the present study was to detect macrophage activities in an ANG II-induced early-stage AAA model using superparamagnetic iron oxide (SPIO as a marker. METHODOLOGY/PRINCIPAL FINDINGS: Twenty-six male apoE(-/- mice received saline or ANG II (1000 or 500 ng/kg/min infusion for 14 days. All animals underwent MRI scanning following administration of SPIO with the exception of three mice in the 1000 ng ANG II group, which were scanned without SPIO administration. MR imaging was performed using black-blood T2 to proton density -weighted multi-spin multi-echo sequence. In vivo MRI measurement of SPIO uptake and abdominal aortic diameter were obtained. Prussian blue, CD68,α-SMC and MAC3 immunohistological stains were used for the detection of SPIO, macrophages and smooth muscle cells. ANG II infusion with 1000 ng/kg/min induced AAA in all of the apoE(-/- mice. ANG II infusion exhibited significantly higher degrees of SPIO uptake, which was detected using MRI as a distinct loss of signal intensity. The contrast-to-noise ratio value decreased in proportion to an increase in the number of iron-laden macrophages in the aneurysm. The aneurysmal vessel wall in both groups of ANG II treated mice contained more iron-positive macrophages than saline-treated mice. However, the presence of cells capable of phagocytosing haemosiderin in mural thrombi also induced low-signal-intensities via MRI imaging. CONCLUSIONS/SIGNIFICANCE: SPIO is taken up by macrophages in the shoulder and the outer layer of AAA. This alters the MRI signaling properties and can be used in imaging inflammation associated with AAA. It is important to compare images of the aorta before and after SPIO injection.

  5. Toward a more rationalized use of a special technique for repair of frontal air sinus after cerebral aneurysm surgery: The most effective technique

    Ittichai Sakarunchai, MD


    Full Text Available A craniotomy that passes through the frontal air sinus (FAS often results in postoperative complications such as infection, cerebrospinal fluid leakage or mucocele formation. A good understanding of FAS reconstruction can decrease the morbidity rate of complications. This study describes the outcomes of treatment and establishes the most effective technique for FAS reconstruction in our institution. We enrolled 107 patients who had a bifrontal craniotomy which exposed the FAS during the operation for an anterior communicating artery (ACoA aneurysm. Demographic data including the follow-up information were collected and analyzed. The complications after surgery were observed and described in the treatment procedure. The patency of the nasofrontal outflow tract (NFOT was proved by removal of blood clots and bone dust by irrigation and by direct inspection under a microscope before closure of the frontal sinus mucosa with a monofilament non-absorbable 7/0 material suture. The dura was closed in a watertight fashion and an abdominal fat graft was packed into the FAS cavity. There were 33 male and 74 female patients and the mean age (range was 64 years (32–90 years. The mean follow-up time was 13 months (1–35 months and complications were found in only 2 patients. One patient suffered from dislocation of the fat graft and the other patient developed a surgical wound infection. At post-operation the first patient sneezed several times and the second patient suffered from trauma in the nasal area after discharge to home. Both patients were surgically treated and cured. In conclusion, FAS reconstruction from our technique is very effective for the prevention of complications after bifrontal craniotomy. Direct suturing of the frontal sinus mucosa and proving the patency of the NFOT are keys to successful treatment.

    Objective To summarize the experience of use of partial cardiopulmonary bypass for surgery of descending thoracic aneurysm. Methods Thirty five patients were undertaken surgery of descending thoracic aneurysm using partial cardiopulmonary bypass and beating-heart technique in our hospital. The partial cardiopulmonary bypass includes left heart bypass (left atrial to femoral artery bypass), pulmonary artery to femoral artery bypass, femoral vein to femoral artery bypass. Results Only one patient died, the other thirty four patients experienced an uneventful recovery. There was no any complication related to partial cardiopulmonary bypass. Conclusion The use of partial cardiopulmonary bypass for surgery of descending thoracic aneurysm can reduce and avoid the complications of nervous system and urinary system effectively.%目的 总结胸降主动脉瘤手术中采用部分体外循环的管理经验.方法 回顾性分析35例胸主动脉瘤手术中采用心脏不停跳部分体外循环资料,包括左心转流(左房-股动脉转流)、肺动脉-股动脉转流、股静脉-股动脉转流.结果 全组患者1例死亡,余34例痊愈出院,未发生体外循环相关的并发症.结论 胸降主动脉瘤手术采用部分体外循环,能有效的减少和避免神经系统和泌尿系统等并发症的发生.

  7. Surgical treatment of aneurysms of the ascending aorta. Twelve years' experience in 66 patients.

    Markewitz, A; Weinhold, C; Kemkes, B M; Reichart, B; Hemmer, W; Klinner, W


    This study presents the results in 66 patients undergoing surgery for concomitant supracoronary vascular interposition and valve replacement carried out at the Department of Cardiac Surgery of the University of Munich, West-Germany, over a period of 12 years (from July 1, 1973 to June 30, 1985) using a technique similar to that described by Wheat. Forty-seven percent of the cases were true aneurysms and 20% chronic dissections. Thirty-three percent of patients had acute dissections. Early mortality was 16% in the total patient population, 9% in the group having true aneurysm and 32% in the group having acute dissection. No early death was observed in association with chronic dissections. The actuarial one-year survival rate in patients with true aneurysm or chronic dissection was 83.6%, and 54.1% in patients with acute dissection. The corresponding 4-year survival rates were 76.4% and 54.1%, respectively. The average improvement according to the New York Heart Association classification was 1.5 grades. These results confirm that the operative approach to ascending aortic aneurysms is superior to medical treatment, with the operative method involving vascular graft without concomitant aortic valve replacement as well as the method described by Wheat having both proved successful.

  10. Patterns and predictors of in-hospital aneurysmal rebleed: An institutional experience and review of literature

    Menon Girish


    Full Text Available Background: Rebleeding is an important cause for mortality following aneurysmal subarachnoid hemorrhage. Early intervention is believed to reduce the risk of rebleeding. However, in developing countries such as India, early intervention is often difficult due to various reasons. The knowledge about the risks and predictors for rebleeding is essential to prioritize the management policy. Aims: To describe the frequency and impact of rebleeding in the modern era of aneurysm care, to study the clinical profile of patients with rebleed and to review the controversial aspects on aneurysmal rebleed. Materials and Methods: This observational study is based on the retrospective analysis of the case records of all patients admitted with aneurysmal subarachnoid hemorrhage (SAH since January 1999 in our institute. Twenty patients rebled after admission before surgical clipping, and these patients formed our study group. The findings were compared with all the major series on rebleeding published in literature. Results: Since January 1999, 952 patients underwent treatment for aneurysmal subarachnoid hemorrhage in our institute. Twenty patients rebled while awaiting surgery following the admission with an incidence of 2.14%. The study group included nine males and eleven females. The age of the patients ranged from 31 to 69 years, but the majority were in the sixth decade. Mean bleed to admission days was 7.9 days (range: 1-27 days, the mean admission to rebleed was 1.42 days (Range: 0-4 and the mean first bleed to rebleed was 9.26 days. The history of loss of consciousness at the time of bleeding was observed in 16 patients. Four patients bled before an angiogram could be performed. Two patients had giant aneurysms, while the rest had small aneurysms; two patients had multiple aneurysms. Angiographic spasm was observed in eight patients. In three patients, rebleeding was precipitated by angiogram. Twelve patients rebled while taking rest or in sleep, while

  11. Optimal timing for early surgery in infective endocarditis: a meta-analysis†

    Liang, Fuxiang; Song, Bing; Liu, Ruisheng; Yang, Liu; Tang, Hanbo; Li, Yuanming


    To systematically review early surgery and the optimal timing of surgery in patients with infective endocarditis (IE), a search for foreign and domestic articles on cohort studies about the association between early surgery and infective endocarditis published from inception to January 2015 was conducted in the PubMed, EMBASE, Chinese Biomedical Literature (CBM), Wanfang and Chinese National Knowledge Infrastructure (CNKI) databases. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality of the method of the included studies was assessed. Then, the meta-analysis was performed using the Stata 12.0 software. Sixteen cohort studies, including 8141 participants were finally included. The results of the meta-analysis revealed that, compared with non-early surgery, early surgery in IE lowers the incidence of in-hospital mortality [odds ratio (OR) = 0.57, 95% confidence interval (CI) (0.42, 0.77); P = 0.000, I2 = 73.1%] and long-term mortality [OR = 0.57, 95% CI (0.43, 0.77); P = 0.001, I2 = 67.4%]. Further, performing operation within 2 weeks had a more favourable effect on long-term mortality [OR = 0.63, 95% CI (0.41, 0.97); P = 0.192, I2 = 39.4%] than non-early surgery. In different kinds of IE, we found that early surgery for native valve endocarditis (NVE) had a lower in-hospital [OR = 0.46, 95% CI (0.31, 0.69); P = 0.001, I2 = 73.0%] and long-term [OR = 0.57, 95% CI (0.40, 0.81); P = 0.001, I2 = 68.9%] mortality than the non-early surgery group. However, for prosthetic valve endocarditis (PVE), in-hospital mortality did not differ significantly [OR = 0.83, 95% CI (0.65, 1.06); P = 0.413, I2 = 0.0%] between early and non-early surgery. We concluded that early surgery was associated with lower in-hospital and long-term mortality compared with non-early surgical treatment for IE, especially in NVE. However, the optimal timing of surgery remains unclear. Additional larger prospective clinical trials will be

  13. Head positioning for anterior circulation aneurysms microsurgery

    Feres Chaddad-Neto


    Full Text Available Objective To study the ideal patient's head positioning for the anterior circulation aneurysms microsurgery. Method We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the patient's head was positioned accordingly to the aneurysm location and the results from the cadaveric study. The effectiveness of the position was noted. Results We could determine mainly two patterns for head positioning for the anterior circulation aneurysms. Conclusion The best surgical exposure is related to specific head positions. The proper angle of microscopic view may minimize neurovascular injury and brain retraction.

    Yoshida, Tetsuya; Oi, Keiji; Shinohara, Naohiro; Mihara, Akane; Yokoyama, Kenji


    We report a case of Takayasu's arteritis who underwent emergency surgery. A 39-year-old female presented with severe back pain. Electrocardiogram demonstrated complete atrio-ventricular (AV) block and acute inferior myocardial infarction. Coronary angiography revealed ostial occlusion of the right coronary artery. Aortography and contrast-enhanced computed tomography revealed dilated and bizarre-shaped aortic root. The remainder of the aorta and its branches appeared normal. She underwent emergency aortic root replacement with valved conduit. Coronary artery bypass grafting to right coronary artery( RCA) using saphenous vein graft was performed concomitantly. Histologic findings of the aortic root were compatible with Takayasu's arteritis. Postoperative angiography showed graft patency. Takayasu arteritis should be considered for differential diagnosis of acute myocardial infarction in young woman.

  15. What are we waiting for? An argument for early surgery for spinal epidural abscesses

    Epstein, Nancy E.


    Background: In the article: Timing and prognosis of surgery for spinal epidural abscess (SEA): A review, Epstein raises one major point; it is imperative that spinal surgeons “take back decision-making” from our medical cohorts and reinstitute early surgery (12.5), high C-reactive protein (>115), positive blood cultures, radiographic cord compression, and significant neurological deficits (e.g., 19–45%). Results: Recognizing these risk factors should prompt early open surgery (41-42.5 to up to the 75% failure rate that accompanies the nonsurgical treatment of SEA, much less the >25% mortality rate?

  18. Early metabolic improvement following bariatric surgery in morbidly obese adolescents.

    Teeple, E A; Teich, S; Schuster, D P; Michalsky, M P


    Bariatric surgery results in durable weight loss and improved comorbidities. The objectives of this study were to examine the efficacy of gastric bypass in reducing comorbid burden and improving metabolic status among morbidly obese adolescents. The medical records of 15 gastric bypass patients were retrospectively reviewed. Changes in metabolic markers were determined at baseline, 1 and 2 years post-operatively. Comparative analysis demonstrated significant improvement in weight, BMI, insulin, HbA1C, C-peptide, %B, %S, IR, cholesterol, percentile cholesterol, TG, percentile TG, HDL, percentile HDL, LDL, percentile LDL, and VLDL. Results support bariatric surgery as a treatment for morbidly obese adolescents with comorbidities.

  19. Pathomechanisms and treatment of pediatric aneurysms.

    Krings, Timo; Geibprasert, Sasikhan; terBrugge, Karel G


    Pediatric aneurysms are rare diseases distinct from classical adult aneurysms and therefore require different treatment strategies. Apart from saccular aneurysms that are more commonly found in older children, three major pathomechanisms may be encountered: trauma, infection, and dissection. The posterior circulation and more distal locations are more commonly encountered in children compared to adults, and there is an overall male predominance. Clinical findings are not only confined to subarachnoid hemorrhage but may also comprise mass effects, headaches or neurological deficits. In traumatic aneurysms, the skull base and distal anterior communicating artery are commonly affected, and the hemorrhage occurs often delayed (2-4 weeks following the initial trauma). Infectious aneurysms are mostly bacterial in origin, and hemorrhage occurs early after a septic embolic shower. Dissecting aneurysms are the most often encountered aneurysm type in children and can lead to mass effect, hemorrhage, or ischemia depending on the fate of the intramural hematoma. Treatment strategies in pediatric aneurysms include endosaccular coil treatment only for the "classical berry-type" aneurysms; in the other instances, parent vessel occlusion, flow reversal, surgical options, or a combined treatment with bypass and parent vessel occlusion have to be contemplated.

  20. "Microbleeding" from intracranial aneurysms: Local hemosiderin deposition identified during microsurgical treatment of unruptured intracranial aneurysms

    Eric S Nussbaum


    Full Text Available Background: During elective surgery for unruptured aneurysms, we have identified a group of patients with hemosiderin staining of the pial surface immediately adjacent to the aneurysm dome suggesting a remote and unrecognized history of microbleeding from the aneurysm. These cases form the basis for this report. Methods: Medical records of 421 unruptured cerebral aneurysm patients treated surgically between January 2003 and September 2010 were retrospectively reviewed. Patients with a history of prior subarachnoid hemorrhage, craniotomy, or significant closed head injury were excluded from review. Records were reviewed for intraoperative descriptions of hemosiderin deposition in the vicinity of the aneurysm as well as history of headaches, time to presentation, comorbidities, aneurysm characteristics, procedures, and radiologic imaging. Results: Local hemosiderin staining immediately adjacent to the aneurysm was identified intraoperatively in 13 cases. Each of these patients had a history of remote atypical headache prior to presentation. Eight of these patients (62% had aneurysms described as particularly "thin-walled" at the time of surgery. Aneurysm locations included the internal carotid artery (ICA (54%, middle cerebral artery (MCA (23%, anterior communicating artery (ACOMMA (15%, and the anterior cerebral artery (ACA (8%. More than half (54% of these patients had a history of smoking, while 31% had hypertension, and 23% had a history of alcohol abuse. Dyslipidemia and family history of aneurysms were present in 15% and hypercholesterolemia was noted in one patient (8%. Conclusion: We suggest this group of patients had suffered a "microbleed" resulting in local hemosiderin deposition next to the aneurysm. The origins and clinical implications of such microbleeds are unknown and warrant further investigation.

    目的 总结破裂前交通动脉瘤早期显微手术治疗经验.方法 回顾分析我院2007年12月~2010年12月48例前交通动脉瘤破裂患者临床资料,包括临床分级、手术时间及疗效等.结果 24 h内手术12例,24 ~48 h手术30例,48~72 h手术6例,术中均成功夹闭动脉瘤颈;术后死亡3例,中等残废3例,1例轻微神经功能障碍,恢复良好11例,完全康复30例.结论 早期手术治疗前交通动脉瘤可明显降低再出血率及改善患者预后,术中颅压的控制、娴熟的显微操作技术及术后并发症的预防是成功的关键.%Objective To summarize the experiences of early microsurgical treatment of ruptured anterior communicating aneurysms ( ACA) . Methods Retrospective analyses of clinical data were made in 48 cases of ruptured ACA from December 2007 to December 2010, which included clinical grading, surgical time, and curative effects, etc. Results Twelve cases, 30 cases, and 6 cases received the surgical operation within 24 h, 24 to 48 h, and 48 to 72 h, respectively, and all the necks of aneurysm were successfully clipped. Three cases died postoperatively. There were 3 cases of moderate disability, 1 case of mild neurological dysfunction, 11 ones with good recovery, and 30 ones with complete recovery. Conclusion Early microsurgical treatment of ruptured anterior communicating aneurysms can dramatically reduce the rate of rehaemorrhagia and improve the prognosis. Control of intracranial pressure during the operation, refined micromanipulative skill, and the precaution of postoperative complications are keys for successful treatment.

  3. Can Early Computed Tomography Angiography after Endovascular Aortic Aneurysm Repair Predict the Need for Reintervention in Patients with Type II Endoleak?

    PurposeThis study was designed to identify parameters on CT angiography (CTA) of type II endoleaks following endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA), which can be used to predict the subsequent need for reinterventions.MethodsWe retrospectively identified 62 patients with type II endoleak who underwent early CTA in mean 3.7 ± 1.9 days after EVAR. On the basis of follow-up examinations (mean follow-up period 911 days; range, 373–1,987 days), patients were stratified into two groups: those who did (n = 18) and those who did not (n = 44) require reintervention. CTA characteristics, such as AAA, endoleak, as well as nidus dimensions, patency of the inferior mesenteric artery, number of aortic branch vessels, and the pattern of endoleak appearance, were recorded and correlated with the clinical outcome.ResultsUnivariate and receiver operating characteristic curve regression analyses revealed significant differences between the two groups for the endoleak volume (surveillance group: 1391.6 ± 1427.9 mm{sup 3}; reintervention group: 3227.7 ± 2693.8 mm{sup 3}; cutoff value of 2,386 mm{sup 3}; p = 0.002), the endoleak diameter (13.6 ± 4.3 mm compared with 25.9 ± 9.6 mm; cutoff value of 19 mm; p < 0.0001), the number of aortic branch vessels (2.9 ± 1.2 compared with 4.2 ± 1.4 vessels; p = 0.001), as well as a “complex type” endoleak pattern (13.6 %, n = 6 compared with 44.4 %, n = 8; p = 0.02).ConclusionsEarly CTA can predict the future need for reintervention in patients with type II endoleak. Therefore, treatment decision should be based not only on aneurysm enlargement alone but also on other imaging characteristics.

  5. Low-profile Visualized Intraluminal Support Junior Device for the Treatment of Intracranial Aneurysms

    Gupta, Mihir; Cheung, Vincent J; Abraham, Peter; Wali, Arvin R; Gabel, Brandon C; Almansouri, Abdulrahman; Pannell, J. Scott; Khalessi, Alexander A


    Objective: Early case series suggest that the recently introduced Low-profile Visualized Intraluminal Support Junior (LVIS Jr.) device (MicroVention-Terumo, Inc., Tustin, CA) may be used to treat wide-necked aneurysms that would otherwise require treatment with intrasaccular devices or open surgery. We report our single-center experience utilizing LVIS Jr. to treat intracranial aneurysms involving 1.8-2.5 mm parent arteries. Methods: We retrospectively reviewed records of patients treated with the LVIS Jr. device for intracranial aneurysms at a single center. A total of 21 aneurysms were treated in 18 patients. Aneurysms were 2-25 mm in diameter; one was ruptured, while three had recurred after previous rupture and treatment. Lesions were distributed across the anterior (n=12) and posterior (n=9) circulations. Three were fusiform morphology. Results: Stent deployment was successful in 100% of cases with no immediate complications. Seventeen aneurysms were treated with stent-assisted coil embolization resulting in immediate complete occlusion in 94% of cases. Two fusiform aneurysms arising from the posterior circulation were further treated with elective clip ligation after delayed expansion and recurrence; no lesions required further endovascular treatment. Four aneurysms were treated by flow diversion with stand-alone LVIS Jr. stent, and complete occlusion was achieved in three cases. Small foci of delayed ischemic injury were noted in two patients in the setting of antiplatelet medication noncompliance. No in-stent stenosis, migration, hemorrhage, or permanent deficits were observed. Good functional outcome based on the modified Rankin Scale score (mRS ≤ 2) was achieved in 100% of cases. Conclusion: Our midterm results suggest that the LVIS Jr. stent may be used for a variety of intracranial aneurysms involving small parent arteries (1.8-2.5 mm) with complete angiographic occlusion, parent vessel preservation, and functional clinical outcomes.

  6. Identification of Predictive Early Biomarkers for Sterile-SIRS after Cardiovascular Surgery.

    Stoppelkamp, Sandra; Veseli, Kujtim; Stang, Katharina; Schlensak, Christian; Wendel, Hans Peter; Walker, Tobias


    Systemic inflammatory response syndrome (SIRS) is a common complication after cardiovascular surgery that in severe cases can lead to multiple organ dysfunction syndrome and even death. We therefore set out to identify reliable early biomarkers for SIRS in a prospective small patient study for timely intervention. 21 Patients scheduled for planned cardiovascular surgery were recruited in the study, monitored for signs of SIRS and blood samples were taken to investigate biomarkers at pre-assigned time points: day of admission, start of surgery, end of surgery, days 1, 2, 3, 5 and 8 post surgery. Stored plasma and cryopreserved blood samples were analyzed for cytokine expression (IL1β, IL2, IL6, IL8, IL10, TNFα, IFNγ), other pro-inflammatory markers (sCD163, sTREM-1, ESM-1) and response to endotoxin. Acute phase proteins CRP, PCT and pro-inflammatory cytokines IL6 and IL8 were significantly increased (pSIRS group at the end of surgery. Soluble TREM-1 plasma concentrations were significantly increased in patients with SIRS (pSIRS after cardiovascular surgery. A combination of normalized IL1β plasma levels, responses to endotoxin and soluble TREM-1 plasma concentrations at the end of surgery are predictive markers of SIRS development in this small scale study and could act as an indicator for starting early therapeutic interventions.

    Full Text Available Mycotic aneurysm could be divided into three types according to their etiology: septic-embolic, cryptogenic and traumatic type. During the period from 1972 to 1974 two cases of mycotic aneurysms have been seen at the Ohio Valley Medical Center - one following a sub acute bacterial endocarditic and another one was two years following surgery for aortofemoral bypass graft. The clinical course of both patients is discussed. The prognosis of mycotic aneurysm is always fatal without surgical intervention. Mycotic aneurysm is a rare entity which is occasionally reported in the literatures. As far as these case reports go the pathology could be divided into three categories according to their etiology, even though the pathology is essentially the same. 1. The septic-embolic or primary mycotic aneurysm in which the aneurysm is secondary to the sepsis which settles in the wall of the artery and destroys the lamina media and finally developing an aneurysm. This type of mycotic aneurysm is, usually seen in any type of septicemia. 2. The cryptogenic or secondary, mycotic aneurysm in which the sepsis takes place in the pra-existing aneurysm of the arterial wall usually due to arteriosclerosis disease. 3. Traumatic or mixed type mycotic aneurysm in which the sepsis and arterial wall damage takes place at the same time.

  9. Early career choices and successful career progression in surgery in the UK: prospective cohort studies

    Richards Jennifer MJ


    Full Text Available Abstract Background Changes to the structure of medical training worldwide require doctors to decide on their career specialty at an increasingly early stage after graduation. We studied trends in career choices for surgery, and the eventual career destinations, of UK graduates who declared an early preference for surgery. Methods Postal questionnaires were sent, at regular time intervals after qualification, to all medical qualifiers from all UK medical schools in selected qualification years between 1974 and 2005. They were sent in the first year after qualification, at year three and five years after qualification, and at longer time intervals thereafter. Results Responses were received from 27 749 of 38 280 doctors (73% at year one, 23 468 of 33151 (71% at year three, and 17 689 of 24 870 (71% at year five. Early career preferences showed that surgery has become more popular over the past two decades. Looking forward from early career choice, 60% of respondents (64% of men, 48% of women with a first preference for a surgical specialty at year one eventually worked in surgery (p Conclusions Surgery is a popular specialty choice in the UK. The great majority of doctors who progressed in a surgical career made an early and definitive decision to do so.

  10. Saphenous vein graft true aneurysms: Report of nine cases and review of the literature

    Davidović Lazar B.


    . We had two such cases developed three and five years after primary operation. In three of our cases ASVG aneurysm showed an atherosclerotic origin, while in 3 non atherosclerotic. The exact mechanism of aneurysm degeneration of the ASVG in arterial position is unknown. There is likely a combination of factors including: - mechanical trauma during vein harvesting and operation [9,30]; - weakness at branching sites in the vein [2,9]; - potential weakness in the vicinity of the venous valves due to absence of the circular muscle cuff in the media of the vessel wall [5]; - infection [16]; - trauma caused by bony structures near the graft [18,30]; - arteritis [13,14,26, 27, 30]; - atherosclerosis [2,3,5-11,18,19,21,24,25]; - hemodinamic factors from the arterial pressure [23]; - transmural ischemie injury of the vein wall due to disrupting of the vasa vasorum after removing of the vein segments [28,29,33]; Brody cold this fenomen „devascularization of the venous graft" [34]; - diffuse nature of this process in patients with multiple aneurysmal changes [20,32] (our cases 2,3,4,6 and 8; - using of the cephalic [9], or superficial femoral vein [1] (case 7; - changed veins (one of our cases. The use of in situ bypass technique for arterial reconstruction would theoretically, minimize endothelial trauma by reducing operative manipulation, preserving vasa vasorum, and eliminating the pressure induced endothelial desquamation that has been associated with mechanical destination of reversed vein graft during their harvest. However, Sassoust [15] in 1986 reported 5 cases of true aneuryms of the ASVG after in situ F-P bypass. After Sassoust's new cases of ASVG aneurysm following F-P in situ bypass surgery were reported [22-24]. CONCLUSION Early ASVG aneurysm formation occurring six months after surgery has been found to be the result of preexisting unrecognized vein wall weakness or injury at the time of harvest, while aneurysm discovered 5 or more years postoperatively, were

    Adelaide Fernanda Ribeiro Cubal


    Full Text Available Nowadays cervical cancer is diagnosed in many women who still want to have children. This led to the need to provide fertility-sparing treatments. The main goal is to maintain reproductive ability without decreasing overall and recurrence-free survival. In this article, we review data on procedures for fertility preservation, namely, vaginal and abdominal trachelectomy, less invasive surgery and neoadjuvant chemotherapy. For each one, oncological and obstetrical outcomes are analyzed. Comparing to traditionally offered radical hysterectomy, the overall oncologic safety is good, with promising obstetrical outcomes.

Acute phase proteins CRP, PCT and pro-inflammatory cytokines IL6 and IL8 were significantly increased (p<0.001 at the end of surgery in all patients but could not distinguish between groups. Normalization of samples revealed significant increases in IL1β changes (p<0.05 and decreased responses to endotoxin (p<0.01 in the SIRS group at the end of surgery. Soluble TREM-1 plasma concentrations were significantly increased in patients with SIRS (p<0.01. This small scale patient study could show that common sepsis markers PCT, CRP, IL6 and TNFα had low predictive value for early diagnosis of SIRS after cardiovascular surgery. A combination of normalized IL1β plasma levels, responses to endotoxin and soluble TREM-1 plasma concentrations at the end of surgery are predictive markers of SIRS development in this small scale study and could act as an indicator for starting early therapeutic interventions.

    AIM: To analyze the difference in disease course and need for surgery in patients with Crohn’s disease (CD). METHODS: Data of 506 patients with incident CD were analyzed (age at diagnosis: 31.5 ± 13.8 years). Both hospital and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which includes incident CD patients diagnosed between January 1, 1977 and December 31, 2008. Follow-up data were collected until December 31, 2009. All patients included had at least 1 year of follow-up available. Patients with indeterminate colitis at diagnosis were excluded from the analysis. RESULTS: Overall, 73 patients (14.4%) required resective surgery within 1 year of diagnosis. Steroid exposure and need for biological therapy were lower in patients with early limited surgery (P < 0.001 and P = 0.09). In addition, surgery rates during follow-up in patients with and without early surgery differed significantly after matching on propensity scores (P < 0.001, HR = 0.23). The need for reoperation was also lower in patients with early limited resective surgery (P = 0.038, HR = 0.42) in a Kaplan-Meier and multivariate Cox regression (P = 0.04) analysis. However, this advantage was not observed after matching on propensity scores (PLogrank = 0.656, PBreslow = 0.498). CONCLUSION: Long-term surgery rates and overall exposure to steroids and biological agents were lower in patients with early limited resective surgery, but reoperation rates did not differ.

    To explore the application and the effect of early recognition of deteriorating patient program in department of cardiac surgery. We used the early recognition of deteriorating patient program in the cardiac surgery groups, including cardiac surgeons, nurses in ward, ICU and operation rooms of the cardiac surgery department, and compared the satisfaction of nurses and doctors, handover time, handover score of critical patients, and rate of unplanned ICU admission before and after the intervention. After using the early recognition of deteriorating patient program, the satisfaction of doctors and nurses was increased, the handover time was lowered 0.56 min/time (t=2.22, Pcardiac patients, enhance the self-confidence of nurses and work efficiency.

  19. [Successful treatment of atrial fibrillation by resection of a congenital aneurysm of the left heart atrium].

    Heigl, F; Steinbeck, G; Rienmüller, R; Kemkes, B M; Klinner, W


    Atrial fibrillation occurred in a 27-year-old patient with a history of globular cardiac enlargement since childhood. Because of the probable causal relationship between the preexisting heart disease-which was supposed to be an enlargement of the left atrium-and the rhythm disturbance, we recommended a surgical intervention. Cardiac surgery revealed a congenital aneurysm of the left atrial appendage which could be resected without any complication. Postoperatively, atrial fibrillation had returned to regular sinus rhythm. The bad prognosis with a high risk of systemic embolism is the reason why early cardiac surgery should be performed after diagnosis of this rare anomaly (20 reported cases) of the left atrium.

  20. Mycotic Abdominal Aortic Aneurysm Secondary to Septic Embolism of a Thoracic Aorta Graft Infection.

    Blanco Amil, Carla Lorena; Vidal Rey, Jorge; López Arquillo, Irene; Pérez Rodríguez, María Teresa; Encisa de Sá, José Manuel


    Mycotic aneurysms account for 1% of abdominal aortic aneurysms. There are very few cases published that describe the formation of mycotic aneurysms after septic embolism due to graft infection. We present the first case to our knowledge to be described in the literature of a mycotic aneurysm caused by septic embolism derived from a thoracic aorta graft infection, treated with conventional surgery leading to a successful outcome and evolution.

  1. Impact of mild renal impairment on early postoperative mortality after open cardiac surgery

    Ghani A


    Full Text Available Preoperative severe renal impairment is included in the risk scores to predict out-come after open cardiac surgery. The purpose of this study was to assess the impact of pre-operative mild renal impairment on the early postoperative mortality after open heart surgery. Data of all cases of open cardiac surgery performed from January 2005 to June 2006 were collec-ted. Cases with preoperative creatinine clearance below 60 mL/min were excluded from the study. Data were retrospectively analyzed to find the impact of renal impairment on short-term outcome. Of the 500 cases studied, 47 had preoperative creatinine clearance between 89-60 mL/min. The overall mortality in the study cases was 6.8%. The mortality was 28.7% in those who developed postoperative ARF, 33.3% in those who required dialysis and 40.8% in those with preoperative mild renal impairment. Binary logistic regression analysis showed that female gender (P = 0.01, preoperative mild renal impairment (P = 0.007 as well as occurrence of multi organ failure (P < 0.001 were the only independent variables determining the early postoperative mortality after cardiac surgeries. Among them, preoperative mild renal impairment was the most significant and the best predictor for early postoperative mortality after cardiac surgery. Our study suggests that renal impairment remains a strong predictor of early mortality even after adjustment for several confounders.

  2. The role of inflammation in cerebral aneurysms

    Ali H Turkmani


    Full Text Available The natural history of unruptured intracranial aneurysms (IAs is poorly understood. At present, risk factors for aneurysm rupture are limited to demographics and rudimentary anatomic features of the aneurysm. The first sign of aneurysm destabilization and rupture may be subarachnoid hemorrhage, a potentially devastating brain injury with high morbidity and mortality. An emerging body of literature suggests a complex inflammatory cascade likely promotes aneurysm wall remodeling and progressive ballooning of the arterial wall, ultimately terminating in aneurysm rupture. These events likely begin with hemodynamic, flow-related endothelial injury; the injured endothelium stimulates inflammation, including the recruitment and transmigration of inflammatory cells, particularly macrophages. Various proteases are secreted by the inflammatory infiltrate, resulting in degradation of the extracellular matrix and the structural changes unique to IAs. Detailed understanding of these inflammatory processes may result in (1 early identification of patients at high risk for aneurysm rupture, perhaps via arterial wall imaging, and (2 targeted, noninvasive therapies to treat or even prevent cerebral aneurysms.

  3. Mega aorta syndrome: a case of thoracic and abdominal aortic aneurysm.

    Wu, William C; Mitchell, Christopher A; Linklater, Derek


    An 83-year-old woman presented to the emergency department (ED) via emergency medical services with the chief complaint of "strokelike symptoms." Physical examination revealed altered mental status, tachycardia, hypotension, and a large nonpulsatile periumbilical mass. Bedside ultrasound revealed a 9-cm abdominal aortic aneurysm with absent central flow. Computed tomography scan demonstrated diffuse thoracic and abdominal aortic dilation with rupture into the mediastinum along with left hemothorax. Repeat beside ultrasound demonstrated abdominal aortic aneurysm rupture not seen on the computed tomography scan. Despite aggressive resuscitation, the patient developed bradycardia, which devolved into pulseless electric activity cardiac arrest. She was unable to be resuscitated. The patient's diffuse aneurysmal dilation places her into the small category of patients with a disease entity known as mega aorta syndrome (MAS). Mega aorta syndrome is defined as aneurysmal dilation of the aorta to greater than 6 cm in diameter. Although not in our case, most cases of MAS are symptomatic before catastrophic presentation. The disease progression for these patients is slow and occurs over years. When this disease is recognized early, a surgery known as the elephant trunk procedure can be performed. This operation replaces the entire aorta in multiple stages. This gives the emergency physician a critical role in the diagnosis and outcome of these patients because they may come through the ED for an unrelated complaint early in the disease process. This case report illustrates an advanced case of MAS.

  4. Long-term results after repair of ruptured and non-ruptured abdominal aortic aneurysm

    Kuzmanović Ilija B.


    Full Text Available INTRODUCTION Abdominal aortic aneurysm can be repaired by elective procedure while asymptomatic, or immediately when it is complicated - mostly due to rupture. Treating abdominal aneurysm electively, before it becomes urgent, has medical and economical reason. Today, the first month mortality after elective operations of the abdominal aorta aneurysm is less than 3%; on the other hand, significant mortality (25%-70% has been recorded in patients operated immediately because of rupture of the abdominal aneurysm. In addition, the costs of elective surgical treatment are significantly lower. OBJECTIVE The objective of this study is to compare long-term survival of patients that underwent elective or immediate repair of abdominal aortic aneurysm (due to rupture, and to find out the factors influencing the long-term survival of these patients. MATERIAL AND METHODS Through retrospective review of prospectively collected data of the Institute for Cardiovascular Diseases of Clinical Center of Serbia, Belgrade, 56 patients that had elective surgery and 35 patients that underwent urgent operation due to rupture of abdominal aneurysm were followed up. Only the patients that survived 30 postoperative days were included in this review, and were followed up (ranging from 2 to 126 months. Electively operated patients were followed during 58.82 months on the average (range 7 to 122, and urgently operated were followed over 52.26 months (range 2 to 126. There was no significant difference of the length of postoperative follow-up between these two groups. RESULTS During this period, out of electively operated and immediately operated patients, 27 and 22 cases died, respectively. There was no significant difference (p>0,05a of long-term survival between these two groups. Obesity and early postoperative complications significantly decreased long-term survival of both electively and immediately operated patients. Graft infection, ventral hernia, aneurysm of

  5. Endovascular Repair of a Ruptured Descending Thoracic Aortic Aneurysm

    DeFrain, Michael; Strickman, Neil E.; Ljubic, Branimir J.; Dougherty, Kathryn G.; Gregoric, Igor D.


    Endovascular aneurysm repair has considerable potential advantages over the surgical approach as a treatment for thoracic aortic rupture, in part because open surgical repair of ruptured thoracic aortic aneurysms is associated with high mortality and morbidity rates. We describe the successful endovascular deployment of stent-grafts to repair a contained rupture of a descending thoracic aortic aneurysm in an 86-year-old man whose comorbidities prohibited surgery. Two months after the procedure, magnetic resonance angiography showed a patent stent-graft, a patent left subclavian artery, and complete exclusion of the aneurysm. PMID:16878637

  6. The surgery and early postoperative radicular pain in cases with multifocal lumbar disc herniation

    Ulutaş, Murat; Çınar, Kadir; Seçer, Mehmet


    Abstract Persistence of postoperative radicular pain after surgery for multifocal disc herniation (MFDH) is a clinical problem. This study aims to evaluate the effects of a combined treatment approach compared with unilateral stabilization on early postoperative radicular pain in patients with MFDH. Age, sex, level of operation, clinical findings, and radicular pain visual analogue scale (VAS) scores before surgery in the early postoperative period and at 3 months after surgery were retrospectively reviewed for 20 cases of multifocal lumbar disc herniation. The combined approach (translaminar and far lateral) was used for 13 cases. Seven cases underwent transforaminal lumbar interbody fusion (TLIF) and unilateral transpedicular stabilization following total facetectomy. The mean age of the sample was 49.4 ± 10.1 years and the female-to-male ratio was 8:12. The mean VAS scores for radicular pain in cases treated with the combined approach were 8.2, 4.07, and 2.3 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean score for radicular pain improved by 50.4% in the early postoperative period and by 72% in the late postoperative period. The mean VAS scores for radicular pain in cases who underwent TLIF and unilateral stabilization after facetectomy were 8.4, 2.1, and 1.4 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean VAS score for radicular pain improved by 75% in the early postoperative period and by 83.3% in the late postoperative period. The combined approach is an effective alternative in cases with MFDH. TLIF and unilateral segmental stabilization provide substantial decompression and eliminate mechanical compression by conserving the height of the intervertebral foramen in the event that sufficient decompression is unable to obtain. We suggest that elimination of chemical mediators, particularly those causing pain in the dorsal ganglion, contributes to

  7. Operative strategy of complex internal carotid artery-posterior communicating artery aneurysms Defensive effect on perioperative nerve injury

    Xinmin Wang; Wende Xiong; Xuqin Li


    BACKGROUND: The two problems in treating intracranial aneurysm are the vascular reconstruction and brain protection, especially for complex internal carotid artery-posterior communicating artery (ICA-PComA)aneurysms.OBJECTIVE: To analyze the anatomic features and operative technique of complex ICA-PComA aneurysms, and investigate how to better protect the brain tissue.DESIGN: A retrospective case analysis.SETTING: Department ofNeurosurgery, Dalian Central Hospital.PARTICIPANTS: Totally 154 inpatients with ICA-PComA aneurysms were selected from the Department of Neurosurgery, Dalian Central Hospital from January 1998 to December 2006, including 19 cases (12.3%)of complex ICA-PComA aneurysms, 8 males and 11 females, 38 - 67 years of age. Informed contents for surgery and observation were obtained from all the patients or their relatives.METHODS: The clinical manifestations, including initial symptoms and Hunt&Hess grading, were observed. Corresponding strategies were selected for different types of ICA-PComA aneurysms. The patients were followed up at 3 months postoperatively. According to the results of Glasgow scoring, the curative effects were classified as good (4 - 5 points), bad (2 - 3 points) and dead (1 point). The results at discharge were taken as early results, whereas the follow-up results as late results.MAIN OUTCOME MEASURES: Clinical manifestations and curative effects of the patients.RESULTS: All the 19 patients with ICA-PComA were involved in the analysis of results. For clinical manifestations, the initial symptoms were subarachnoid hemorrhage (n =15), paralysis of oculomotor nerve (n =3), and occasional attack (n =1); The Hunt&Hess grading was grade Ⅰ in 4 cases, grade Ⅱ in 6 cases,grade Ⅲ in 6 cases, grade Ⅳ in 2 cases, and grade Ⅴ in 1 case. The curative effects were that aneurysm breakage and bleeding occurred in 6 cases perioperatively, uncomplete clipping of aneurysm in 2 cases and constriction of parent artery in 1 case. The

  8. Ruptured venous aneurysm of cervicomedullary junction

    Ashish Aggarwal


    Full Text Available Background: Ruptured venous aneurysm is often seen with arterio-venous malformation (AVM or developmental venous anomaly (DVA. However, isolated venous aneurysm is unusual. Case Description: We present a case of ruptured venous aneurysm that presented with subarachnoid hemorrhage (SAH and intraventricular hemorrhage (IVH. Digital substraction angiography (DSA revealed a saccular contrast filling pouch in the left lateral aspect of cervicomedullary junction (CMJ. Endovascular intervention was not a viable option. During surgery, a saccular pliable structure approx. 1.5 Χ 1 cm was found in the subarachnoid space that was clipped and excised. There were no arterial feeders, no evidence of surrounding AVM, and no dilated perimedullary vein. Conclusion: This is perhaps the first reported case of ruptured venous aneurysm (without associated AVM of CMJ, which was successfully managed surgically. The possible etiologies remain an unnoticed head trauma or a congenital vessel wall abnormality. Surgically clipping and excision remains the treatment of choice for such lesion.

  9. [Inflammatory aneurysms of the abdominal aorta].

    Tovar Martín, E; Acea Nebril, B


    Approximately 10 per cent of abdominal aneurysms have an excessively thick wall that sometimes involve duodenum, cava or colon by an inflammatory process. Between February 1986 and December 1992, 147 patients with abdominal aortic aneurysm (AAA) were treated surgically and in 13 (8.8%) the aneurysms were found to be inflammatory. Their mean age was 67.3 years (70.1 years in non inflammatory group) and all were symptomatics initially (abdominal pain in 53%, rupture in 23%, mass in 15%). The operative mortality for elective resection was 37% in patients with inflammatory abdominal aortic aneurysms (IAAA) decreasing to 9% in the AAA group without inflammatory involvement. We conclude that surgery is indicated in these patients to prevent rupture and to hasten the subsidense of inflammatory process ever with postoperative morbi-mortality increased.

  10. Treatment strategies for aneurysms associated with moyamoya disease.

    Zhang, Lei; Xu, Kan; Zhang, Yandong; Wang, Xin; Yu, Jinlu


    The treatment of aneurysms associated with moyamoya disease (MMD) is difficult for neurosurgeons, and little is known of strategy options. This report constitutes a comprehensive review of the literature. We summarize the known treatments and their clinical outcomes according to the site of the aneurysm: in major arteries, peripheral arteries, moyamoya vessels, meningeal arteries, or at the site of anastomosis. The literature review indicates that the treatment of MMD-associated aneurysms varies according to the site of the aneurysm and its hemodynamic characteristics. In particular, the treatment for basilar tip aneurysms remains challenging, since both endovascular embolization and direct clipping are difficult. The potential risk for ischemia should be considered in selecting endovascular or surgical approaches. Revascularization surgery, which is important for the treatment of MMD, also determines the clinical treatment outcome of aneurysms associated with MMD.

  12. A randomized controlled trial evaluating early versus traditional oral feeding after colorectal surgery

    Ahmet Dag


    Full Text Available OBJECTIVE: This prospective randomized clinical study was conducted to evaluate the safety and tolerability of early oral feeding after colorectal operations. METHODS: A total of 199 patients underwent colorectal surgery and were randomly assigned to early feeding (n = 99 or a regular diet (n = 100. Patients’ characteristics, diagnoses, surgical procedures, comorbidity, bowel movements, defecation, nasogastric tube reinsertion, time of tolerance of solid diet, complications, and length of hospitalization were assessed. RESULTS: The two groups were similar in terms of gender, age, diagnosis, surgical procedures, and comorbidity. In the early feeding group, 85.9% of patients tolerated the early feeding schedule. Bowel movements (1.7±0.89 vs. 3.27±1.3, defecation (3.4±0.77 vs. 4.38±1.18 and time of tolerance of solid diet (2.48±0.85 vs. 4.77±1.81 were significantly earlier in the early feeding group. There was no change between the groups in terms of nasogastric tube reinsertion, overall complication or anastomotic leakage. Hospitalization (5.55±2.35 vs. 9.0±6.5 was shorter in the early feeding group. CONCLUSIONS: The present study indicated that early oral feeding after elective colorectal surgery was not only well tolerated by patients but also affected the postoperative outcomes positively. Early postoperative feeding is safe and leads to the early recovery of gastrointestinal functions.

  13. [Aortic aneurysm].

    Villar, Fernando; Pedro-Botet, Juan; Vila, Ramón; Lahoz, Carlos


    Aortic aneurysm is one important cause of death in our country. The prevalence of abdominal aortic aneurism (AAA) is around 5% for men older than 50 years of age. Some factors are associated with increased risk for AAA: age, hypertension, hypercholesterolemia, cardiovascular disease and, in particular, smoking. The medical management of patients with an AAA includes cardiovascular risk treatment, particularly smoking cessation. Most of major societies guidelines recommend ultrasonography screening for AAA in men aged 65 to 75 years who have ever smoked because it leads to decreased AAA-specific mortality.

    Vaquero Morillo, F; Zorita Calvo, A; Fernández-Samos Gutiérrez, R; García Vázquez, J; Ortega Martín, J M; Fernández Morán, C


    We presented the review of 22 cases of popliteal aneurysms with a follow-time of three years. One case was a woman and 5 cases were bilaterals. The most part of cases begun as a latter acute ischemia. Sixteen cases were treated surgically, with a null rate of mortality, 2 amputations, 4 cases of residual intermittent claudication and 10 no-symptomatic patients, with present distal pulses. Etiology, clinical presentation, diagnosis, technics and results are presented and a comparison with other authors is made. Our experience support an interventionist attitude in cases of elderly nonsymptomatic patients, performed by internal way and saphenous vein substitution.

  15. Endothelial dysfunction in the early postoperative period after major colon cancer surgery

    Ekeløf, Sara; Larsen, Mikkel Hjordt; Schou-Pedersen, Anne Marie Voigt


    Background. Evidence suggests that endothelial dysfunction in the early postoperative period promotes myocardial injury after non-cardiac surgery. The aim of this study was to investigate the impact of colon cancer surgery on endothelial function and the association with the l-arginine-nitric oxide...... pathway postoperatively. Methods. Patients undergoing elective colon cancer surgery (n = 31) were included in this prospective observational cohort study.

  16. Outcomes after endovascular aneurysm repair conversion and primary aortic repair for urgent and emergency indications in the Society for Vascular Surgery Vascular Quality Initiative.

    Scali, Salvatore T; Runge, Sara J; Feezor, Robert J; Giles, Kristina A; Fatima, Javairiah; Berceli, Scott A; Huber, Thomas S; Beck, Adam W


    Open conversion after endovascular aortic aneurysm repair (EVAR-c) is performed nonelectively in up to 60% of cases. EVAR-c has been reported to have significantly greater risk of postoperative morbidity and mortality than primary aortic repair, but few data exist on outcomes for symptomatic or ruptured presentations. This study determined outcomes and identified predictors of postoperative major adverse cardiac events (MACEs) and mortality for patients undergoing nonelective EVAR-c compared with nonelective primary aortic repair (PAR) in the Vascular Quality Initiative (VQI). All VQI patients undergoing urgent/emergency EVAR-c or urgent/emergency PAR from 2002 to 2014 were reviewed. Urgent presentation was defined by repair ≤24 hours of a nonelective admission, and emergency operations had clinical or radiographic evidence, or both, of rupture. End points included in-hospital MACE (myocardial infarction, dysrhythmia, congestive heart failure) and 30-day mortality. Possible covariates identified on univariate analysis (P emergency repair. nonelective PAR was performed in 1388 of 6152 total (23%). EVAR-c patients were older (75 ± 9 vs 71 ± 10 years; P coronary artery disease (38% vs 27%; P = .01). No differences in MACE (EVAR-c, 31% [n = 34] vs PAR, 30% [n = 398]) or any major postoperative complication (EVAR-c, 57% [n = 63] vs PAR, 55% [n = 740]; P = .8) were found; however, 30-day mortality was significantly greater in EVAR-c (37% [n = 41]) than in (PAR, 24% [n = 291]; P = .003), with an odds ratio (OR) of 2.2 (95% confidence interval [CI], 1.04-4.77; P = .04) for EVAR-c. Predictors of any MACE included age (OR, × 1.03 for each additional year; 95% CI, 1.01-1.03; P = .0002), male gender (OR, 1.3; 95% CI, 1.03-1.67; P = .03), body mass index ≤20 kg/m(2) (OR, 1.8; 95% CI, 1.13-2.87; P = .01), chronic obstructive pulmonary disease (OR, 1.2; 95% CI, 0.86-1.80; P = .25), congestive heart failure (OR, 1.5; 95% CI, 0.98-2.34; P = .06

  18. Screening for popliteal aneurysms should not be a routine part of a community-based aneurysm screening program

    Martin Claridge


    Full Text Available Martin Claridge1, Simon Hobbs1, Clive Quick2, Donald Adam1, Andrew Bradbury1, Teun Wilmink11University Department of Vascular Surgery, Birmingham Heartlands Hospital, Birmingham, UK; 2Department of Surgery, Hinchingbrooke Hospital, Huntingdon, UKIntroduction: Several studies have found an increased incidence of peripheral aneurysms in patients with an abdominal aortic aneurysm (AAA. The aim of this study was to determine whether screening for popliteal aneurysms should be part of an AAA screening programme.Setting: A community-based AAA screening programmeMethods: The diameters of the internal abdominal aorta and both popliteal arteries were assessed by B-Mode ultrasound in a subgroup of the screened population. An AAA was defined as an infrarenal aortic diameter >29 mm. A popliteal aneurysm was defined as a popliteal diameter >19 mm.Results: Information was available for 283 subjects, 112 subjects with a small AAA, and 171 subjects with a normal aorta. No popliteal aneurysms were found in the subjects with a normal aorta. Three popliteal aneurysms were found in patients with a small AAA. Scanning both popliteal arteries took an experienced sonographer on average three times as long as scanning for an AAA (5 vs 15 minutes.Conclusion: Popliteal artery aneurysms are seen in less than 3% of men with a small AAA and not at all in men with a normal aortic diameter. It is therefore not cost effective to include screening for popliteal aneurysms in population screening for AAA.Keywords: popliteal aneurysm, screening program

    In this study, we analyzed the procedural success and early outcome of endovascular treatment of a multicenter cohort of patients with common iliac artery (CIA) aneurysms treated with the new GORE EXCLUDER (W. L. Gore & Associates, Flagstaff, Ariz) iliac branch endoprosthesis (IBE). A retrospective cohort analysis was performed in 13 sites in The Netherlands. Anatomic, demographic, procedural, and follow-up data were assessed from hospital records. From November 2013 to December 2014, 51 CIA aneurysms were treated with an IBE in 46 patients. The median diameter of the treated aneurysm was 40.5 (range, 25.0-90.0) mm. The mean procedural time was 198 ± 56 minutes. All but one implantation were successful; two type Ib endoleaks were noticed, resulting in a procedural success rate of 93.5%. The two type Ib endoleaks spontaneously disappeared at 30 days. There was no 30-day mortality. Ipsilateral buttock claudication was present in only two cases at 30 days and disappeared during follow-up. The incidence of reported erectile dysfunction was low and severe ischemic complications were absent. After a mean follow-up of 6 months, data on 17 treated aneurysms were available. Two showed a stable diameter, whereas 15 showed a mean decrease of 3.9 ± 2.2 mm (P GORE EXCLUDER IBE device for CIA aneurysms is related to high procedural success, high patency rates, and low reintervention rates at short-term follow-up. Prospective data with longer follow-up are awaited to establish the role of the device in the treatment algorithm of CIA aneurysms. Copyright © 2016 Society for Vascular Surgery.

  3. Subarachnoid hemorrhage with blister aneurysms: Endovascular management

    Swati Dayanand Chinchure


    Full Text Available Blister aneurysms of are rare lesions representing a real challenge for diagnosis and management. They typically show small size, hemispherical shape, fragile wall, broad neck, and are arising from non-branching sites of intracranial arteries. Materials and Methods: We retrospectively reviewed all aneurysms treated at our institution. Seventeen patients (6 male, 11 female with 17 blister aneurysms were identified (mean age 53.3, range 41-63 years. Clinical, procedural, angiographic data as well as follow up data were evaluated. Results: All patients presented with aneurysmal subarachnoid hemorrhage. Majority of the blister aneurysms were located in ICA while 1 was located at posterior cerebral artery, 1 at vertebral and 1 involving basilar artery. All patients were treated using single or overlapping stents and if possible additional coiling. There was no intra-operative rupture. Good outcome (mrs 0-2 was seen in 14 patients. Poor clinical outcome (mrs 3-5 was seen in 2 patients due to vasospasm induced ischemic deficits at discharge, both of them improved on follow up (mrs 1 on follow up. There were 3 mortalities, One patient died of rebleeding while other 2 died due to SAH induced complications. Follow-up angiography was available in 16 patients (one patient died before follow up angiogram and revealed complete or near complete aneurysm occlusion in 11, incomplete obliteration in 1 and no change in 2 cases. Two cases showed post-treatment angiographic aneurysm recurrence. Both cases were managed with repeat coiling and overlapping stent placement. Conclusion: Endovascular management using single/overlapping stent and if possible coil placement is technically safe and feasible in blister aneurysms. Overlapping stents lead to better aneurysm occlusion than a single stent. Blister aneurysm in dorso-medial ICA showed higher tendency of continued growth/recurrence, higher incidence of clinical vasospasm and in these cases early angiographic follow

    Background Abdominal aortic aneurysms requiring surgical intervention are generally treated by endovascular means. Such procedures are not always offered in rural hospitals, possibly leaving patients underserved. We reviewed our experience initiating an endoaortic surgery program. Methods A surgeon in a rural centre was credentialed to perform endovascular aortic aneurysm repair through collaboration with a university centre and was proctored locally for the first 5 abdominal aneurysm repairs. Web-based image storage was used to review complex cases as part of an ongoing partnership. Referred patients were screened for multiple aneurysms and underwent long-term monitoring. Results In all, 160 patients were evaluated for 176 aortic pathologies. Twenty-five patients (17 men) aged 55–89 years underwent 26 endovascular abdominal (n = 23) or thoracic (n = 3) aortic procedures. Emergent endovascular procedures were not performed. There were no operative deaths, requirements for dialysis or conversions to open repair. Two endoleaks required early reintervention. The median length of stay in hospital for endovascular procedures was 2.5 days. Chronic endoleaks were observed in 7 patients. An additional 8 patients underwent open abdominal aneurysm repair locally and 15 patients were referred to the university program. Conclusion Creation of an endovascular aortic surgery program in a rural hospital is feasible through collaboration with a high-volume centre. Patient safety is enhanced by obtaining second opinions using web-based image review. Most interventions are for abdominal aortic aneurysms, but planning for a comprehensive aortic clinic is preferable. PMID:24067525

  5. Superficial temporal artery-middle cerebral artery bypass surgery in a pediatric giant intracranial aneurysm presenting as migraine-like episodes.

    Goedee, H S; Depauw, P R A M; vd Zwam, B; Temmink, A H


    Aneurysms of the intracranial arteries in the pediatric population are reportedly rare. There is a male predominance, association with connective tissue disorders, as well as bacterial, mycotic infections, and trauma. Common sites of presentation are the internal carotid artery bifurcation, posterior circulation, and distal segment of middle cerebral artery. Clinical manifestations can vary from seizures and subarachnoidal hemorrhage to headache, irritability, lethargy, vomiting, or focal motor deficits. Current treatment modalities encompass endovascular or surgical approach. We present a case report on an 11-year-old girl with migraine-like episodes due to an underlying giant fusiform middle cerebral artery aneurysm treated successfully with two superficial temporal artery-middle cerebral artery bypasses.

    Mohammadtaghi Rajabi Mashhadi


    Full Text Available Introduction: Early diagnosis and appropriate treatment is required in esophageal cancer due to its invasive nature. The aim of this study was to evaluate early post-esophagectomy complications in patients with esophageal cancer who received neoadjuvant chemoradiotherapy (NACR.   Materials and Methods: This randomized clinical trial was carried out between 2009 and 2011. Patients with lower-third esophageal cancer were randomly assigned to one of two groups. The first group consisted of 50 patients receiving standard chemoradiotherapy (Group A and then undergoing surgery, and the second group consisted of 50 patients undergoing surgery only (Group B. Patients were evaluated with respect to age, gender, clinical symptoms, type of pathology, time of surgery, perioperative blood loss, and number of lymph nodes resected as well as early post-operative complicate including leakage at the anastomosis site, chylothorax and pulmonary complications, hospitalization period, and mortality rate within the first 30 days after surgery.   Results: The mean age of patients was 55 years. Seventy-two patients had squamous cell carcinoma (SCC and 28 patients had adenocarcinoma (ACC. There was no significant difference between the two groups with respect to age, gender, time of surgery, complications including anastomotic leakage, chylothorax, pulmonary complications, cardiac complications, deep venous thrombosis (DVT, or mortality. However, there was a significant difference between the two groups regarding hospital stay, time of surgery, perioperative blood loss, and number of lymph nodes resected.   Conclusion:  The use of NACR did not increase early post-operative complications or mortality among patients with esophageal cancer.

  8. Fatores de morbimortalidade na cirurgia eletiva do aneurisma da aorta abdominal infra-renal: experiência de 134 casos Morbidity and mortality factors in the elective surgery of infrarenal abdominal aortic aneurysm: a case study with 134 patients

    Aquiles Tadashi Ywata de Carvalho


    aortic aneurysm (AAA can result in serious complications. To optimize treatment outcome it is important to identify patients at risk of having complications and implement prophylaxis. OBJECTIVES: To analyze early surgical mortality rate and postsurgical complications, and to identify risk factors related to morbidity and mortality. METHOD: A total of 134 patients with infrarenal AAA submitted to elective surgical correction from February 2001 to December 2005 were analyzed. RESULTS: The mortality rate (5.2% was secondary mainly to acute myocardial infarction and intestinal ischemia. Heart-related complications were the most frequent, followed by lung and kidney complications. Presence of diabetes mellitus, congestive heart failure, coronary artery disease, and scintigraphy suggestive of ischemia were related to cardiac complications. Advanced age, chronic obstructive lung disease and reduced forced vital capacity were related to higher risks of atelectasis and pulmonary infection. Presence of renal failure, prolonged aortic clamping and high urea rates were related to acute renal failure. Smoking and advanced age were associated with lower limb ischemia. Presence of obstructive coronary insufficiency and prolonged aortic clamping and surgery time were associated with higher mortality rate. CONCLUSION: The morbidity and mortality rate was compatible with data found in the national and international literature, secondary to cardiac, pulmonary and kidney complications. Identified risk factors before and during the surgery were related to these complications.

    Laparoscopic surgery for this disease is not widely spread due to difficulties in its procedure. We started a laparoscopic procedure for this disease since 2011, and the robotic surgery since 2012. The aim of this study is to assess early results of these procedures. We have operated seven cases from September 2011 through December 2013. First two cases were performed by laparoscopic procedure, and following cases were done by robotically assisted surgery. Of these cases, the perioperative outcome and short-term postoperative morbidity were evaluated. Their average age was 43.6 years old (20-64 years old), and male-female ratio was 2:5. Todani classification was type 1 in all cases. The operation time was 321 min in laparoscopic cases, while 489 min in robotic surgery cases. One case of robotic surgery developed postoperative intestinal obstruction of the biliary limb, requiring laparoscopic adhesiolysis. Pancreatic fistula and anastomotic leakage have not been observed. The robotic surgery for the congenital dilatation of the bile duct is feasible and is a theoretically useful option, especially for hepatico-jejunostomy. On the other hand, the limitation of energy devices, high running cost, and time consumption remain questionable.

  11. Arterial Ligation for Infected Femoral Psuedo-Aneurysm in Drug Injecting Abusers

    Mohammadzade Mohammad Ali


    Full Text Available Pseudo-aneurysm of the femoral artery is the most common arterial complication in drug injecting abusers. Scholars in vascular surgery have published debating statements regarding techniques of successful surgical management during last two decades. We present the results of simple arterial ligation in a series of 32 patients presenting with infected femoral pseudo-aneurysm. Most of the patients were males (89%. Young persons in the age group of 15-44 years were mostly affected. Site of lesion included common femoral artery in 65% , superficial femoral artery 28% and at bifurcation 6.2%. celulitis in 14 (53%, abscess & "ncelulitis in 6 (19%, necrosing fasciitis in 2 (6.2% and vascular abscess in 7 (22% cases were the forms of associated local infection. There was no hemorrhage, vascular thrombosis, amputation, or mortality. Claudicating were the only complications identified in 2 patients with Tripe ligation. Ligation is the optimal management for infected pseudo-aneurysms because it is easy, cost-effective, and safe. Early reconstruction is not recommended, since there is an extended infection in the location of the pseudo-aneurysm.

  12. Sepsis following cancer surgery: the need for early recognition and standardised clinical care.

    Hiong, A; Thursky, K A; Teh, B W; Haeusler, G M; Slavin, M A; Worth, L J


    Despite the implementation of multimodal bundles of care in hospitalised patients, post-operative sepsis in patients with cancer still accounts for a significant burden of illness and substantial healthcare costs. Patients undergoing surgery for cancer are at particular risk of sepsis due to underlying malignancy, being immunocompromised associated with cancer management and the complexity of surgical procedures performed. In this review, we evaluate the burden of illness and risks for sepsis following surgery for cancer. Current evidence supporting standardised strategies for sepsis management (including early recognition and resuscitation) is examined together with challenges in implementing quality improvement programs.

  14. The transforming power of early career acute care surgery research scholarships on academic productivity.

    Zarzaur, Ben L; Valsangkar, Nakul; Feliciano, David F; Koniaris, Leonidas G


    More than 75% of respondents to an Eastern Association for the Surgery of Trauma survey felt that barriers to research had increased and that acute care surgeon (ACS) academic productivity had decreased. Recent data confirm this impression and show lower academic productivity of junior ACS faculty compared with peers in other general surgical fields. The purpose of this study was to determine if early career acute care surgery research scholarships are associated with improved ACS academic productivity. Faculty data at the Top 55 National Institutes of Health (NIH)-funded departments of surgery (Top 55) were obtained using SCOPUS, NIH, department, and professional society databases. Academic productivity was measured using total publications, citations, and the Hirsch index. Scholarship recipients from the American Association for the Surgery of Trauma and Eastern Association for the Surgery of Trauma were identified. A total of 4,101 surgical faculty (8.3% ACS) who belong to the Top 55 NIH-funded departments of surgery and 85 scholarship recipients were identified. After merging, 34 scholarship recipients (40%) were current faculty at a Top 55 NIH-funded department of surgery, and 24 of those (71%) were ACS faculty. Scholarship recipients had higher median total publications compared with nonrecipients at assistant and associate ranks but not at full professor rank. For all ranks, scholarship recipients were more likely to have NIH funding compared with nonrecipients (33% vs. 11%, p publications, with an average of 89 more publications over a career (p ACS faculty in Top 55 NIH-funded departments of surgery. Among junior ACS faculty, recipients are associated with increased academic productivity and NIH funding. To fill the academic productivity gap among junior ACSs, professional organizations should consider increasing research funding scholarships for promising investigators.

  15. Long-term outcome of 114 children with cerebral aneurysms.

    Koroknay-Pál, Päivi; Lehto, Hanna; Niemelä, Mika; Kivisaari, Riku; Hernesniemi, Juha


    Population-based data on pediatric patients with aneurysms are limited. The aim of this study is to clarify the characteristics and long-term outcomes of pediatric patients with aneurysms. All pediatric patients (≤ 18 years old) with aneurysms among the 8996 aneurysm patients treated at the Department of Neurosurgery in Helsinki from 1937 to 2009 were followed from admission to the end of 2010. There were 114 pediatric patients with 130 total aneurysms during the study period. The mean patient age was 14.5 years (range 3 months to 18 years). The male:female ratio was 3:2. Eighty-nine patients (78%) presented with subarachnoid hemorrhage. The majority of the aneurysms (116 [89%]) were in the anterior circulation, and the most common location was the internal carotid artery bifurcation (36 [28%]). The average aneurysm diameter was 11 mm (range 2-55 mm) with 16 giant aneurysms (12%). Eighty aneurysms (62%) were treated microsurgically, and 37 (28%) were treated conservatively due to poor medical and neurological status of the patient or due to technical reasons during the early years of the patient series. No connective tissue disorders common to pediatric aneurysm patients were diagnosed in this series, with the exception of 1 patient with tuberous sclerosis complex. The mean follow-up duration was 24.8 years (range 0-55.8 years). At the end of follow-up, 71 patients (62%) had a good outcome, 3 (3%) were dependent, and 40 (35%) had died. Twenty-seven deaths (68%) were assessed to be aneurysm-related. Factors correlating with a favorable long-term outcome were good neurological condition of the patient on admission, aneurysm location in the anterior circulation, complete aneurysm closure, and absence of vasospasm. Six patients developed symptomatic de novo aneurysms after a median of 25 years (range 11-37 years). Fourteen patients (12%) had a family history of aneurysms. There was no increased incidence for cardiovascular diseases in long-term follow-up. Most

  16. Stent-assisted coil embolization of a recurrent posterior cerebral artery aneurysm following surgical clipping.

    Takeshita, Tomonori; Nagamine, Tomoaki; Ishihara, Kohei; Kaku, Yasuhiko


    Posterior cerebral artery (PCA) aneurysms are rare, and direct surgery of these is considered difficult. Coil embolization of PCA aneurysms is becoming popular. However, it is difficult to completely obliterate the aneurysm while preserving the flow of the parent artery in large or giant PCA aneurysms with a wide neck with this technique. We report a case of a large and wide-necked PCA aneurysm with multiple recurrences following successful surgical clipping and coil embolization. A 77-year-old man with a large unruptured right PCA (P2) aneurysm was successfully treated by surgical clipping. Postoperative digital subtraction angiography (DSA) showed complete aneurismal occlusion. Four years afterward, the aneurysm recurred and grew toward the contralateral. Surgical retreatment of this complicated aneurysm was considered difficult, with a substantial risk of complications. Therefore, the aneurysm was treated with an endovascular procedure. Because simple coil embolization was not expected to achieve satisfactory obliteration of the aneurysm with preservation of parent artery patency, we used stent-assisted coil embolization. The patient tolerated the treatment well. On DSA obtained six months after the first endovascular treatment, coil compaction and recanalization of the aneurysm were detected. A second coil embolization was successfully performed without any complications. The aneurysm was stable during the next six-month follow-up. Stent-assisted coil embolization may be feasible and effective for such postoperatively complicated aneurysms.

  17. Junctional Internal Carotid Artery Aneurysms: The Schrödinger's Cat of Vascular Neurosurgery.

    Carlson, Andrew P; Loveren, Harry R van; Youssef, A Samy; Agazzi, Siviero


    Objectives Despite advances in neuroimaging, it is not always definitive whether a paraclinoid aneurysm is intradural or entirely extradural. We illustrate the potential use of surgical exploration in these aneurysms that we refer to as "junctional" aneurysms. Methods Retrospective review of eight patients with unruptured aneurysms who underwent a planned surgical exploration of a junctional aneurysm. Results Of the eight patients, three underwent exploration of the aneurysm during surgery for a different aneurysm. All three of these were found to be extradural. Five patients underwent a craniotomy for the exclusive purpose of clarifying the location of the aneurysm. Two of these cases were found to be intradural and were clipped. Two cases were found to be extradural. In one patient, the initially extradural aneurysm was converted into an intradural aneurysm during removal of the anterior clinoid process, necessitating surgical clipping. One transient third nerve palsy was observed. Discussion Until further progress in neuroimaging allows clinicians to determine unequivocally the exact anatomical location of a paraclinoid aneurysm, we advocate the use of the term junctional aneurysm to reflect the clinical uncertainty inherent in management decisions made regarding these aneurysms. We have illustrated a strategy of surgical exploration in select patients.

  18. Risk factors responsible for the volume of hemorrhage in aneurysmal subarachnoid hemorrhage

    Jianfeng Liu


    Conclusion: Preadmission DBP, multiple aneurysms, and aneurysms of the ACOA are associated with markedly increased volume of hemorrhage as evaluated by the revised Fisher grades. Thus, patients harboring an intracranial aneurysm having the above mentioned features should seek an early intervention in order to prevent the occurrence of aSAH.

    Full Text Available Objectives: Poor nutritional status following abdominal surgeries for esophageal and gastric cancers remains a major challenge in postoperative care. Our study aimed to investigate the efficacy of starting early oral feeding (EOF in patients undergoing surgical resection of upper gastrointestinal malignancies. Methods: A total of 180 consecutive patients with a diagnosis of esophageal or gastric malignancies undergoing elective surgical resection between January 2008 and February 2011 were enrolled in this prospective cohort study. Seventy-two patients were assigned to the EOF group, and 108 patients received late oral feeding (LOF. Postoperative endpoints were compared between the two groups. Results: Nasogastric tubes were removed from patients on average 3.3±1.6 days after the surgery in the EOF group and 5.2±2.5 days in the LOF group (p 0.050. Conclusions: EOF is safe following esophageal and gastric cancer surgery and results in faster recovery and hospital discharge.

    Subarachnoid hemorrhage (SAH) is rare in young adults and little is known about aneurysms in this subgroup. The effect of clinical and prognostic factors on the outcome based on the Glasgow Outcome Scale (GOS) scores and the predictors of unfavorable outcomes were analyzed in young adults with aneurysmal SAH. A retrospective review of the clinical parameters, including age, sex, hypertension, smoking status, hyperlipidemia, location of the cerebral aneurysm, size of the aneurysm, multiplicity, perioperative complication such as hydrocephalus, vasospasm, and hematoma, and Hunt and Hess and Fisher grading on presentation, was conducted in 108 young adults (mean age 34.8 years) managed at our institute. The outcome was classified based on GOS grading into unfavorable (GOS scores 1-3) or favorable (GOS scores 4 or 5). The overall mortality rate was 3.7% (4/108 patients). Univariate regression analysis for the outcomes at discharge found that age at the time of presentation, male sex, size of aneurysm, multiple aneurysms, hyperlipidemia, and poor Hunt and Hess and Fischer grades were associated with unfavorable outcome. Multivariate regression analysis found independent effects of sex, multiple aneurysms, size of aneurysm, and Hunt and Hess grade on the outcome at discharge. Size of aneurysm, presence of multiple aneurysms, Hunt and Hess grade, and hypertension were the predictors of outcome at mean 2-year follow up based on multivariate exact regression analysis. The multimodal approach with aggressive medical management, early intervention, and surgical treatment might contribute to favorable long-term outcomes in patients with poor expected outcomes.

  6. Long-term Results of Breast-conserving Surgery and Radiation Therapy in Early Breast Cancer

    Kim, Jin Hee; Byun, Sang Jun [Dongsan Medical Center, Daegu (Korea, Republic of)


    To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10{approx}16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13{approx}179 months, with a median of 92.5 months. The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ({<=}6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.

    To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. Ninety-two early major complications occurred in 76 patients (13%). Age > 60 years and surgery of three or more levels proved to be significant independent risk factors in the multivariate analysis. The balanced scoring system was defined as: 0 points (no risk factor), 2 points (1 factor) or 4 points (2 factors). The incidence of early major complications in each category was 7% (0 points), 15% (2 points) and 29% (4 points) respectively. This balanced scoring system, based on two risk factors, represents an important tool for both surgical indication and for patient counseling before surgery.

    To investigate the effect of early rehabilitation on neurofunctional outcome after surgery in chil-dren with spinal tumors, this study reviewed the medical charts and radiographic records of 70 pediatric patients (1-17 years old) who received spinal tumor surgical removal. The peddiatric patients received rahabilitation treatment at 4 (range, 2-7) days after surgery for 10 (range, 7-23) days. Results from the Modiifed McCormick Scale, Functional Independence Measure for Chil-dren, American Spinal Injury Association Impairment Scale and Karnofsky Performance Status Scale demonstrated that the sensory function, motor function and activity of daily living of pedi-atric children who received early rehabilitation were signiifcantly improved. Results also showed that tumor setting and level localization as well as patients’s clinical symptoms have no inlfuences on neurofunctional outcomes.

    Del Santo, Molly Ann; Cordina, Steve Mario


    Intracranial aneurysms in the pediatric population are rare. We report a case of a 3-month-old infant who presented with inconsolable crying, vomiting, and sunset eye sign. CT revealed a subarachnoid hemorrhage, with CT angiogram revealing a superior cerebellar artery aneurysm. An external ventricular drain was placed for acute management of hydrocephalus, with definitive treatment by endovascular technique with a total of six microcoils to embolize the aneurysm. Serial transcranial Dopplers revealed no subsequent vasospasm. Although aneurysms in the pediatric population are rare, once the diagnosis is established, early treatment results in better outcomes. 2016 BMJ Publishing Group Ltd.

  10. Lessons on the pathogenesis of aneurysm from heritable conditions

    Lindsay, Mark E.; Dietz, Harry C.


    Aortic aneurysm is common, accounting for 1–2% of all deaths in industrialized countries. Early theories of the causes of human aneurysm mostly focused on inherited or acquired defects in components of the extracellular matrix in the aorta. Although several mutations in the genes encoding extracellular matrix proteins have been recognized, more recent discoveries have shown important perturbations in cytokine signalling cascades and intracellular components of the smooth muscle contractile apparatus. The modelling of single-gene heritable aneurysm disorders in mice has shown unexpected involvement of the transforming growth factor-β cytokine pathway in aortic aneurysm, highlighting the potential for new therapeutic strategies.

  11. Early continuous venovenous hemodialysis in dialysis-dependent patients after cardiac surgery: safety and efficacy.

    Nakasuji, Masato; Nishi, Shinichi; Nakasuji, Kae; Hamaoka, Naoya; Ikeshita, Kazutoshi; Asada, Akira


    The present study assessed the safety and efficacy of continuous venovenous hemodialysis (CVVHD) early after cardiac surgery. Retrospective database and medical record review. University teaching hospital. Forty-five dialysis-dependent patients who underwent cardiac surgery with cardiopulmonary bypass. CVVHD was begun postoperatively after confirmation of hemostasis, irrespective of circulatory status. In the last 5 patients, the ratio of extravascular lung water (EVLW) to intrathoracic blood volume (ITBV) was measured using a single-indicator thermodilution catheter and compared with patients of normal renal function undergoing cardiac surgery. CVVHD was started at 4 hours after ICU admission. The maximum decrease in blood pressure within 60 minutes after initiation of CVVHD was 11 +/- 9 mmHg in the unstable hemodynamics group (defined as patients who required continuous intravenous adrenaline or intra-aortic balloon pump on admission to the ICU [n = 15]) and 7 +/- 8 mmHg in the stable hemodynamics group (n = 30, not significant). Circulatory status and oxygenation improved significantly 12 hours after CVVHD initiation in the unstable hemodynamics group. Blood volume from the chest tube did not increase after CVVHD. Early mortality (2.2%) was lower than that reported previously. The EVLW/ITBV ratio after ICU admission in dialysis-dependent patients was significantly higher than in patients with normal renal function. Early CVVHD after cardiac surgery in dialysis-dependent patients was safe and effective. There was no associated increased postoperative bleeding or hemodynamic instability. Fluid removal improved respiratory status, particularly in patients requiring circulatory assistance, and overall early morality rates were lower that those previously published.

  13. Protective Effect of Surgery Against Early Subtalar Arthrodesis in Displaced Intra-articular Calcaneal Fractures

    Liu, Yueju; Li, Zhi; Li, Heng; Zhang, Yingze; Wang, Pengcheng


    Abstract The aim of this study is to determine whether surgery offers protection against early subtalar arthrodesis in displaced intraarticular calcaneal fractures. Systematic review and meta-analysis: searches of electronic databases 1980 to August 2014, checking of reference lists, hand searching of journals, and contact with experts. Randomized controlled trials (RCTs) in which surgical treatment was compared with nonsurgical treatment of displaced intra-articular calcaneal fractures from 1980 to 2014. The modified Jadad scale was used for trial quality and effective data were pooled for meta-analysis. Study results related to early subtalar arthrodesis were extracted and risk assessment was combined with surgical treatment and nonsurgical treatment. The primary analysis included 4 studies and 966 participants. The estimated overall risk ratio was 4.40 (95% confidence interval 2.67–7.39), indicating the incidence of early subtalar arthrodesis in nonsurgical group is 4.4 times the surgical group. The results showed that surgical treatment was superior to nonsurgical treatment in protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures (Z = 5.600, P < 0.001). Surgery offers protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures. PMID:26559281

  14. Coronary artery aneurysms

    Koischwitz, D.; Harder, T.; Schuppan, U.; Thurn, P.


    Seven saccular coronary artery aneurysms have been demonstrated in the course of 1452 selective coronary artery angiograms. In six patients they were arterio-sclerotic; in one patient the aneurysm must have been congenital or of mycotic-embolic origin. The differential diagnosis between true aneurysms and other causes of vascular dilatation is discussed. Coronary artery aneurysms have a poor prognosis because of the possibility of rupture with resultant cardiac tamponade, or the development of thrombo-embolic myocardial infarction. These aneurysms can only be diagnosed by means of coronary angiography and require appropriate treatment.

  15. Renal replacement therapies after abdominal aortic aneurysm repair--a review.

    Hudorović, Narcis; Lovricević, Ivo; Brkić, Petar; Ahel, Zaky; Vicić-Hudorović, Visnja


    The objective of this review is to assess the incidence of postoperative acute renal failure that necessitates the application of hemofiltration and to determine the factors that influence the outcome in patients undergoing surgical repair of abdominal aortic aneurysm. In addition, the review aims to assess the outcomes of postoperative early hemofiltration as compared to late intensive hemofiltration. Different forms of renal replacement therapies for use in abdominal aortic aneurysm surgery patients are discussed. Electronic literature searches were performed using Pubmed, Medline, Embase, Sumsearch, Cinahil, The Cochrane Central Register of Controlled Trials and Excerpta Medica. The search identified 419 potentially eligible studies, of which 119 were excluded based on the title and abstract. Of the remaining 300 studies, full articles were collected and re-evaluated. Forty-five articles satisfied our inclusion criteria, of which only 12 were of the IA Level of evidence. The search results indicated that the underlying disease, its severity and stage, the etiology of acute renal failure, clinical and hemodynamic status of the patient, the resources available, and different costs of therapy might all influence the choice of the renal replacement therapy strategy. However, clear guidelines on renal replacement therapy duration are still lacking. Moreover, it is not known whether in acute renal failure patients undergoing abdominal aortic aneurysm surgery, renal replacement therapy modalities can eliminate significant amounts of clinically relevant inflammatory mediators. This review gives current information available in the literature on the possible mechanisms underlying acute renal failure and recent developments in continuous renal replacement treatment modalities.

    The purpose of this study was to assess the efficacy of tolvaptan, a vasopressin V2 receptor antagonist, for the management of postoperative surgical fluid retention after heart valve surgery. This was a prospective observational study of 64 patients with heart valve disease who underwent valve surgery between 2013 and 2014. Those in the tolvaptan group received tolvaptan in addition to conventional diuretic therapy. The results were compared to the results of 55 patients who underwent heart valve surgery between 2007 and 2010 and received conventional postoperative diuretics alone. The time to return to the preoperative BW was significantly shorter in the patients who received tolvaptan (6.1 ± 3.8 vs. 8.7 ± 6.7 days, p fluid retention during the early postoperative stage in cardiac surgery patients, without increased renal failure or abnormal electrolyte levels. This new type of diuretic therapy may be a suitable option for postoperative fluid management in patients undergoing cardiac surgery.

  18. Single-port video-assisted thoracic surgery for early lung cancer: initial experience in Japan

    Takeuchi, Shingo; Usuda, Jitsuo


    Background Single-port video-assisted thoracic surgery (SPVATS) emerged several years ago as a new, minimally invasive surgery for diseases in the field of respiratory surgery, and is increasingly becoming a subject of interest for some thoracic surgeons in Europe and Asia. However, the adoption rate of this procedure in the United States and Japan remains low. We herein reviewed our experience of SPVATS for early lung cancer in our center, and evaluated the safety and minimal invasiveness of this technique. Methods We retrospectively analyzed patients who had undergone SPVATS for pathological stage I lung cancer in Nippon Medical School Chiba Hokusoh Hospital between September 2012 and October 2015. In SPVATS, an approximately 4-cm incision was made at the 4th or 5th intercostal space between the anterior and posterior axillary lines. A rib spreader was not used at the incision site, and surgical manipulation was performed very carefully in order to avoid contact between surgical instruments and the intercostal nerves. The same surgeon performed surgery on all patients, and analyzed laboratory data before and after surgery. Results Eighty-four patients underwent anatomical lung resection for postoperative pathological stage I lung cancer. The mean wound length was 4.2 cm. Eighty-four patients underwent lobectomy and segmentectomy, respectively. The mean preoperative forced expiratory volume in 1 second (FEV1%) was 1.85%±0.36%. Our patients consisted of 49 men (58.3%) and 35 women (41.7%), with 64, 18, 1, and 1 having adenocarcinoma, squamous cell carcinoma, adenosquamous carcinoma, and small-cell lung cancer, respectively. The mean operative time was 175±21 min, operative blood loss 92±18 mL, and duration of drain placement 1.9±0.6 days. The duration of the postoperative hospital stay was 7.1±1.7 days, numeric rating scale (NRS) 1 week after surgery 2.8±0.6, and occurrence rate of allodynia 1 month after surgery 10.7%. No patient developed serious

  20. Giant venous aneurysm jeopardising internal mammary arterial graft patency.

    Van Caenegem, Olivier; le Polain de Waroux, Jean-Benoit; de Kerchove, Laurent; Coche, Emmanuel


    The authors report a 79-year old man with a history of coronary bypass surgery, presenting with acute heart failure and elevated troponin. Coronarography revealed a giant saphenous vein graft aneurysm, which was compressing the left internal mammary artery bypass graft. This was confirmed by a multislice enhanced-ECG gated cardiac CT, showing the venous aneurysm responsible for external compression of the arterial graft and its functional occlusion. Myocardial ischaemia, the mechanism leading to cardiac failure, was confirmed by hypoperfusion of the sub-endocardial area shown by the CT. The aneurysm was surgically removed without complications. The patient recovered and his cardiac function improved. This is the first recorded case of compression of the left internal mammary artery by an giant saphenous vein graft aneurysm having triggered severe myocardial ischaemia and heart failure. The authors review the incidence and complications of giant venous bypass graft aneurysms reported in the literature.

  1. A case of a huge gastroepiploic arterial aneurysm.

    Ikeda, Hirokuni; Takeo, Masahiko; Mikami, Ryuuichi; Yamamoto, Mistuo


    An 85-year-old man complaining of vague abdominal discomfort was admitted to our hospital. A pulsatile 8 × 7-cm mass in the right upper abdomen was noticed on clinical examination. Computed tomography of the abdomen showed a huge arterial aneurysm in the right gastroepiploic artery, and the left gastroepiploic artery was meandering and expanding. An image diagnosis of gastroepiploic arterial aneurysm (GEAA) was made. Because of the huge size of the aneurysm and the predicted high risk of perforation, surgical intervention was planned. The aneurysm was identified in the greater curve and was found to adhere firmly to the transverse colon. Partial resection of the stomach, aneurysmectomy and partial resection of the transverse colon were performed. Clinically, splanchnic arterial aneurysms are rare. Among them, GEAA is especially rare. We report a rare case of a huge GEAA that was treated successfully by surgery. Published by Oxford University Press and JSCR Publishing Ltd. All rights reserved. © The Author 2015.

  2. Posterior spinal artery aneurysm rupture after 'Ecstasy' abuse.

    Johnson, Jeremiah; Patel, Shnehal; Saraf-Lavi, Efrat; Aziz-Sultan, Mohammad Ali; Yavagal, Dileep R


    Posterior spinal artery (PSA) aneurysms are a rare cause of subarachnoid hemorrhage (SAH). The commonly abused street drug 3,4-methylenedioxymethamphetamine (MDMA) or 'Ecstasy' has been linked to both systemic and neurological complications. A teenager presented with neck stiffness, headaches and nausea after ingesting 'Ecstasy'. A brain CT was negative for SAH but a CT angiogram suggested cerebral vasculitis. A lumbar puncture showed SAH but a cerebral angiogram was negative. After a spinal MR angiogram identified abnormalities on the dorsal surface of the cervical spinal cord, a spinal angiogram demonstrated a left PSA 2 mm fusiform aneurysm. The patient underwent surgery and the aneurysmal portion of the PSA was excised without postoperative neurological sequelae. 'Ecstasy' can lead to neurovascular inflammation, intracranial hemorrhage, SAH and potentially even de novo aneurysm formation and subsequent rupture. PSA aneurysms may be treated by endovascular proximal vessel occlusion or open surgical excision.

  3. [Effect of early surgery in essential infantile esotropia on the quality of binocular vision].

    Autrata, R; Hromádková, L; Rehůrek, J


    In a retrospective study of 397 children operated in the course of 10 years (1985-1995) on account of essential infantile esotropia the authors evaluate the effect of early surgery implemented before the age of two years on the quality of binocular vision as compared with a later operation. The group of children was divided into three sub-groups. Group A comprised 75 children with the operation during the first six months of life (mean 3.8 months), sub-group B 194 children with the operation at the age of 6-24 months and in group C 128 children operated at the age of 2-6 years (mean 3.56 years). In group A binocular vision was recorded in 80% children (15% superposition, 60% fusion, 5% stereopsy). In groups B binocular vision was recorded in 76% children (18% superposition, 50% fusion, 8% stereopsy). In group C simple binocular vision in the form of superposition was present in 24% and fusion only in 21% children. The results of binocular vision after surgery of essential infantile esotropia are in favour of early surgery, preferably by the age of 6 months, not later than at the age of 2 years. An essential part of comprehensive treatment is active and positive pleoptic and orthoptic care incl. supplementary surgical correction of residual horizontal or vertical deviations. Early surgery of an adequate extent with a safeguarded parallel position of the eyes implies in the long run more frequent achievement of a higher quality of binocular vision incl. stereopsy.

  4. Endovascular treatment of coarctation and related aneurysms.

    Galiñanes, E L; Krajcer, Z


    Today,surgical repair has almost doubled the 30year survival rate in patients with coarctation of the aorta (CoA), and 72% to 98% of patients now reach adulthood. Possible late complications include malignant hypertension, left ventricular dysfunction, aortic valve dysfunction, recurrent CoA, and aneurysm formation with risk of rupture. Treating postoperative CoA-related aneurysms with observation alone is associated with a mortality rate of 36%, compared with 9% for surgical repair. Even in the best surgeons' hands, aortic surgery has associated complications, and the complexity of reoperative surgery makes the risks substantially greater. For patients with CoA-related aneurysm, endovascular treatment constitutes a good alternative to reoperative surgery because it poses a lower risk of morbidity and mortality. Implanting an endograft has been shown to be successful in treating CoA and related aneurysms, producing excellent intermediate outcomes and minimal morbidity and mortality. Despite evidence that using covered stents improves outcomes, the superiority of any particular stent type has yet to be established. With a variety of endografts available, the decision of which stent to use depends on anatomy, availability, and operator preference.

  7. [Usefulness of upper gastrointestinal series to detect leaks in the early postoperative period of bariatric surgery].

    Medina, Francisco J; Miranda-Merchak, Andrés; Martínez, Alonso; Sánchez, Felipe; Bravo, Sebastián; Contreras, Juan Eduardo; Alliende, Isabel; Canals, Andrea


    Postoperative leaks are the most undesirable complication of bariatric surgery and upper gastrointestinal (GI) series are routinely ordered to rule them out. Despite the published literature recommending against its routine use, it is still being customarily used in Chile. To examine the usefulness of routine upper GI series using water-soluble iodinated contrast media for the detection of early postoperative leaks in patients undergoing bariatric surgery. A cohort of 328 patients subjected to bariatric surgery was followed from October 2012 to October 2013. Most of them underwent sleeve gastrectomy. Upper GI series on the first postoperative day were ordered to 308 (94%) patients. Postoperative leaks were observed in two patients, with an incidence of 0.6%. The sensitivity for upper GI series detection of leak was 0% and the negative predictive value was 99%. Routine upper GI series after bariatric surgery is not useful for the diagnosis of postoperative leak, given the low incidence of this complication and the low sensitivity of the technique.

    Full Text Available AIM: The research aims to determine the influence of early goal-oriented physical therapy program in combination with educational booklet and standard physical therapy without written instructions on functional mobility outcomes in patients after low back surgery. MATERIAL AND METHODS: Thirty patients with similar functional impairments were randomly divided into two groups, a control group (СG n = 10 and an experimental group (EG n = 20. The outcome measures include time to move from lying to sitting position, the TUG test and the 6-meter walk test. Rehabilitation program includes daily physical therapy with mild to moderate intensity, achieving sitting position and education sessions how to perform activities of daily living (ADL from the first day after surgery. RESULTS: There was a significant improvement from baseline in two groups for all performed tests (p < 0.001. Statistical significant differences between two groups for transfers in bed on discharge (p < 0.05, in one month (p < 0.01 and for TUG in one month (p < 0.05 were found. CONCLUSION: The study revealed that early rehabilitation program consists of therapeutic exercises and written educational booklet after low back surgery improves transfer abilities and basic activities in one month.

  9. Early cardiology assessment and intervention reduces mortality following myocardial injury after non-cardiac surgery (MINS)

    Hua, Alina; Pattenden, Holly; Leung, Maria; Davies, Simon; George, David A.; Raubenheimer, Hilgardt; Niwaz, Zakiyah


    Background Myocardial injury after non-cardiac surgery (MINS) is defined as troponin elevation of ≥0.03 ng/mL associated with 3.87-fold increase in early mortality. We sought to determine the impact of cardiology intervention on mortality in patients who developed MINS after general thoracic surgery. Methods A retrospective review was performed in patients over 5 years. Troponin was routinely measured and levels ≥0.04 ng/mL classified as positive. Data acquisition and mortality status was obtained via medical records and NHS tracing systems. Thirty-day mortality was compared on MINS cohort using Fisher’s exact square testing and logistic regression analysis. Results Troponin levels were measured in 491 (96%) of 511 patients. Eighty (16%) patients fulfilled the MINS criteria. Sixty-one (76%) received early cardiology consult and “myocardial infarction” stated in four (5%) patients. Risk assessment (for AMI) was undertaken; 20 (25%) patients were commenced on aspirin, four (5%) on β-blockers and one (1%) underwent percutaneous coronary intervention. Forty-nine (61%) patients received primary risk factor modifications and 26 (33%) had outpatient follow-up. There were no significant differences in the proportion of patients who died within 30 days post-operatively in the MINS group of 2.6% compared to the non-MINS group of 1.6% (P=0.625). The odds ratio for 30-day mortality in the MINS group was 1.69 (95% CI: 0.34 to 8.57, P=0.522). Conclusions MINS is common after general thoracic surgery. Early cardiology intervention reduced the expected hazard ratio of early death from 3.87 to an odds ratio of 1.69 with no significant difference in 30-day mortality for patients who developed MINS.

    Timofeev, M E; Breusenko, V G; Shapoval'iants, S G; Fedorov, E D; Larichev, S E; Kretsu, V N


    It is presented the results of diagnostic and curative laparoscopic interventions in 33 patients with acute early adhesive small bowel obstruction. Ileus developed after surgical treatment (laparotomy) of different gynecological diseases. Laparoscopy appeared as the most informative diagnostic method to confirm diagnosis in all patients, to estimate state of abdominal cavity and small pelvis organs what can help to determine method of surgical treatment. Contraindications for laparoscopic surgery were identified in 12 (36.4%) patients and conversion to laparotomy was applied in this group. Postoperative complications were diagnosed in 1 (8.3%) patient. 2 (16.6%) patients died. Early adhesive ileus was resolved laparoscopically in 21 (63.6%) of 33 patients. Recurrent acute early adhesive ileus was detected in 1 (4.7%) patient.

    SHANG Yan-guo


    Full Text Available Objective To discuss the individualized management strategy for intracranial vertebral artery dissecting aneurysms. Methods Eighteen patients with intracranial vertebral artery dissecting aneurysms were treated with different surgical methods. Results Eighteen patients underwent different surgical treatment. Five patients underwent complete occlusion of the aneurysm and parent artery by coiling, 5 were treated by stent -assisted coiling (3 densely packed coiling and 2 non-densely packed coiling, 4 underwent stent-only therapy and 3 of them presented hemodynamic improvement after surgery, 3 were treated by direct surgical clipping, and 1 underwent occipital artery-posterior inferior cerebellar artery bypass. Two aneurysms ruptured immaturely, in which one patient died on the third day after operation and one patient occurred moderate disablity. Only 1 patient who underwent complete occlusion of aneurysm and parent artery presented temporarily ischemic symptoms. No adverse effects were seen in other patients. Seventeen patients were followed up for 1 month to 3 years, and all the aneurysms were stable. Conclusion There are many kinds of therapeutic methods for intracranial vertebral artery dissecting aneurysms. The patients should be treated according to several factors such as the clinical manifestations, aneurysm configuration, and relationship with the posterior inferior cerebellar artery. The treatment should be individualized.

  14. Tuberculous aneurysm of the abdominal aorta: endovascular repair using stent grafts in two cases

    Liu, Wei Chiang; Kwak, Byung Kook; Kim, Kyo Nam [Sung Ae General Hospital, Seoul (Korea, Republic of); And Others


    Tuberculous aneurysm of the aorta is exceedingly rare. To date, the standard therapy for mycotic aneurysm of the abdominal aorta has been surgery involving in-situ graft placement or extra-anatomic bypass surgery followed by effective anti-tuberculous medication. Only recently has the use of a stent graft in the treatment of tuberculous aortic aneurysm been described in the literature. We report two cases in which a tuberculous aneurysm of the abdominal aorta was successfully repaired using endovascular stent grafts. One case involved is a 42-year-old woman with a large suprarenal abdominal aortic aneurysm and a right psoas abscess, and the other, a 41-year-old man in whom an abdominal aortic aneurysm ruptured during surgical drainage of a psoas abscess.

    Full Text Available ABSTRACT: INTRODUCTION: Bone infections after implant surgery leading to non union and implant failure is one of the most challenging Ortho paedic complications. This study is done to find out relation of type of pathogens causing postope rative infection with that of fracture nonunion, chronic osteomylities and implant failure. METHODOLOGY: This is a retrograde study of 20 cases, in which post operative wound infe ction occurred after implant surgery from 2009 to 2012. Results: Out of 20 postoperative infect ed cases, 12 were infected by S ’ \\aureus, 2 by pseudomonas and 1 from E-coli. 5 cases had their culture sterile. Out of 12 cases infected by S. aureus 7 developed infected non union in which 4 had serious infection also leading to chronic osteomylities.5 cases of S aureus infection got cured after implant removal following union. CONCLUSION: Most of the postoperative wound infections are cause d by S. aureus. 2-.S. aureus is the commonest organism isolated from infe cted non-union. Majority have early onset of infection. 3-Early culture positive infection (w ithin seven days after surgery have poor out come.4- In our setup S Aurous strain is sensitive t o linezolid, clindamycin and vancomycin. 5- The use of ceftriaxone for preoperative surgical pro phylaxis in orthopaedic implant surgery is questionable.6- The ideal strategy for S. aureus in fected implant is lacking. By surgical debridement, culture sensitivity specific antibiotic for 6 to 8 week and retention of implant, union were not achieved in majority of cases. 7-New approach is required for prevention and management of postoperative S. aureus infected implan t

    AIM: To compare the outcomes of a cohort of Crohn’s disease(CD) patients undergoing early surgery(ES) to those undergoing initial medical therapy(IMT).METHODS: We performed a review of a prospective database CD patients managed at a single tertiary institution. Inclusion criteria were all patients with ileal or ileocolonic CD between 1995-2014. Patients with incomplete data, isolated colonic or perianal CD were excluded. Primary endpoints included the need for, and time to subsequent surgery. Secondary endpoints included the number and duration of hospital admissions, and medical therapy. RESULTS: Forty-two patients underwent ES and 115 underwent IMT. The operative intervention rate at 5 years in the ES group was 14.2% vs IMT 31.3%(HR = 0.41, 95%CI: 0.23-0.72, P = 0.041). The ES group had fewer hospital admissions per patient [median 1 vs 3(P = 0.012)] and fewer patients required anti-TNF therapy than IMT(33.3% vs 57%, P = 0.003). A subgroup analysis of 62 IMT patients who had undergone surgery were compared to ES patients, and showed similar 5 year(from index surgery) re-operation rates 16.1% vs 14.3%. In this subset, a significant difference was still found in median number of hospital admissions favouring ES, 1 vs 2(P = 0.002).CONCLUSION: Our data supports other recent studies suggesting that patients with ileocolonic CD may have a more benign disease course if undergoing early surgical intervention, with fewer admissions to hospital and atrend to reduced overall operation rates.

Ocorreram 7,6% óbitos tardios, distribuídos no Grupo Bom 4,8%, Grupo Regular 7,4% e Grupo Ruim 23,8%. Analisando as curvas atuariais numa evolução até 8,5 anos, os autores concluem que a expectativa de vida para os portadores de aneurisma, de VE que se submetem a tratamento cirúrgico, com ou sem procedimentos associados, é de 85,5% com Fe = 0,58; 87,7% com Fe = 0,35 e 59,3% com Fe = 0,22.We revewed 305 cases with left ventricular aneurysms undertaken to surgery from January 84 to December 91 analising early results since the late follow-up that ranged from 8 months to 8.5 years, and included all patients discharged alive from hospital. There were 88.5% male, with age ranging from 33 to 78 years (46% of patients between 51 to 60 years. The most frequent clinical finding was chest pain (73.3%, followed byheartfailure (45.9%, arrhythmias (24.9%. Fifty four percent of the patients were in functional class 1,5.2% in II, 12.7% in III and 28.7% in class IV. Left ventricular angiogram showed aneurysms and diskinesis in all cases, and coronary angiography showed single vessel coronary artery disease (CAD in 20.9%, 2 vessel CAD in 45.9%, 3 vessel CAD in 25.9% and 4 or more vessels CAD in 7.2%. Patients were divided in groups according to left ventricular wall motion of the non aneurysmatic areas. There was 34.7% in the good group (mean wall motion = 0.58, 54.7% in the regular group (mean wall motion = 0.35 and 10.4% in the bad group (mean wall motion = 0.22. The used surgical technique included the observation of the beating heart under bypass auxiliary. This aided the differentation of fibrostic and contracting areas. This also allowed better preservation of the physiology of the myocardium during the procedure. In selected cases after opening the aneurysm and removing thrombus, coronaries were

  18. Aneurysm growth after late conversion of thoracic endovascular aortic repair

    Hirofumi Kasahara


    Full Text Available A 69-year-old man underwent thoracic endovascular aortic repair of a descending aortic aneurysm. Three years later, he developed impending rupture due to aneurysmal expansion that included the proximal landing zone. Urgent open surgery was performed via lateral thoracotomy, and a Dacron graft was sewn to the previous stent graft distally with Teflon felt reinforcement. Postoperatively, four sequential computed tomography scans demonstrated that the aneurysm was additionally increasing in size probably due to continuous hematoma production, suggesting a possibility of endoleaks. This case demonstrates the importance of careful radiologic surveillance after endovascular repair, and also after partial open conversion.

  19. Aneurysm of the superficial palmar arch: a case report.

    Estrella, Emmanuel P; Lee, Ellen Y


    Aneurysms of the hand are uncommon lesions. The most common location is the ulnar artery. We present a case of a young female who consulted us for a hand mass with a history of trauma to the hand. Pre-operative arteriogram showed a superficial palmar arch aneurysm. The mass was excised and the arch was reconstructed using a reversed Y-shaped vein graft. Fourteen months after surgery, there was no recurrence of the aneurysm and the patient only reported occasional cold intolerance.

  20. Transient cortical blindness after thoracic endovascular aneurysm repair.

    Vallabhaneni, Raghuveer; Jim, Jeffrey; Derdeyn, Colin P; Sanchez, Luis A


    We report a patient who presented with transient cortical blindness 12 hours after completion of a thoracic endovascular aneurysm repair. Computed tomography of the brain demonstrated no acute findings. The patient's symptoms resolved spontaneously after 72 hours. To our knowledge, this is the first report of transient cortical blindness after endovascular aortic aneurysm repair. This is an uncommon diagnosis that is important to recognize in a modern vascular surgery practice.

  1. Is a sedentary lifestyle an independent predictor for hospital and early mortality after elective cardiac surgery?

    Noyez, L; Biemans, I; Verkroost, M; van Swieten, H


    This study evaluates whether a sedentary lifestyle is an independent predictor for increased mortality after elective cardiac surgery. Three thousand one hundred fifty patients undergoing elective cardiac surgery between January 2007 and June 2012 completed preoperatively the Corpus Christi Heart Project questionnaire concerning physical activity (PA). Based on this questionnaire, 1815 patients were classified as active and 1335 patients were classified as sedentary. The endpoints of the study were hospital mortality and early mortality. The study population had a mean age of 69.7 ± 10.1 (19-95) years and a mean logistic EuroSCORE risk of 5.1 ± 5.6 (0.88-73.8). Sedentary patients were significantly older (p = 0.001), obese (p = 0.001), had a higher EuroSCORE risk (p = 0.001), and a higher percentage of complications. Hospital mortality (1.1 % versus 0.4 % (p = 0.014)) and early mortality (1.5 % versus 0.6 % (p = 0.006)) were significantly higher in the sedentary group compared with the active group. However, a sedentary lifestyle was not identified as an independent predictor for hospital mortality (p = 0.61) or early mortality (p = 0.70). Sedentary patients were older, obese and had a higher EuroSCORE risk. They had significantly more postoperative complications, higher hospital mortality and early mortality. Despite these results, sedentary behaviour could not be identified as an independent predictor for hospital or early mortality.

  2. Early Functional Outcomes of Periacetabular Osteotomy After Failed Hip Arthroscopic Surgery for Symptomatic Acetabular Dysplasia.

    Ricciardi, Benjamin F; Fields, Kara G; Wentzel, Catherine; Kelly, Bryan T; Sink, Ernest L


    Persistent acetabular dysplasia is a common reason for the failure of hip arthroscopic surgery; however, the effect of prior hip arthroscopic surgery on functional outcomes after subsequent periacetabular osteotomy (PAO) is unknown. Hypothesis/Purpose: The purpose of this study was to (1) compare demographic and radiological findings in patients who had and had not undergone previous hip arthroscopic surgery before PAO for symptomatic acetabular dysplasia and (2) compare the short-term, hip-specific patient-reported outcomes in these same patient populations. It was hypothesized that prior hip arthroscopic surgery is associated with worse early functional outcomes in PAO. Cohort study; Level of evidence, 3. A retrospective cohort study design was utilized. Patients undergoing PAO were enrolled from a single-center, prospective hip preservation registry from March 2011 to April 2015. Patients with a minimum of 1-year clinical follow-up with preoperative and postoperative outcome scores undergoing PAO were eligible for inclusion (n = 93 patients; mean clinical follow-up, 24 months [range, 11-58 months]). The study group consisted of patients undergoing PAO for symptomatic hip dysplasia after prior hip arthroscopic surgery (PREVSCOPE group; 22 patients, 25 hips). Patients undergoing PAO without prior hip arthroscopic surgery (PAOALONE group; 71 patients, 85 hips) were included as a comparison group. Demographic and radiological variables were recorded. Postoperative functional outcome scores (modified Harris Hip Score [mHHS], Hip Outcome Score [HOS], and International Hip Outcome Tool [iHOT-33]) were recorded at 6 months and annually postoperatively. There were no demographic differences between the 2 groups at baseline. Acetabular version, femoral version, Tönnis grade, preoperative lateral center edge angle, and intraoperative procedures were not different between the 2 groups. At 1-year follow-up from the last hip surgical procedure, the mean (±SD) mHHS (73 ± 14

    Hasegawa, Takatoshi; Horiuchi, Tetsuyoshi; Hongo, Kazuhiro


    Reports on histological changes of vascular wall following clipping surgery have been scarce. The authors experienced a case of unruptured cerebral aneurysm in which the tissue occluded by clip blades for 6 years was obtained and histologically examined. The aneurysmal wall following clipping showed granulomatous inflammation with necrosis, and occluded aneurysmal walls were found with collagenous fibrous tissue. Mild infiltration by lymphocytes and fibrous thickened intima occurred.

    Objective To explore the diagnostic procedure, operative time and microsurgical technique in the patients with intracranial aneurysm Methods The clinical data of 65 intracranial aneurysms patients underwent microsurgery in our hospital from September 2005 and July 2009 were analyzed retrospectively. Results There were 76 intracranial aneurysms in 56 patients, including 70 cases of clipped aneurysms, 4 cases were wrapped aneurysms and 2 cases were ruptured aneurysms. According to GOS, of 65 patients with intracranial aneurysms, 58 patients were recovered well, 3 patients were moderately disabled, 2 patients were severely disabled, 1 patient vegetatively survived and 1 died after the surgery. Conclusions CT, magnetic resonance angiography, CT angiography and Digital subtraction angiography can provide important information for diagnosis of intracranial aneurysms. Microsurgi-cal clipping of intracranial aneurysms still is a reliable and effective method. Early microsurgery for ruptured in-tracranial aneurysms can decrease rebleeding, disabled rate and mortality.%目的 探讨颅内动脉瘤的诊断、手术时机和显微手术方法.方法 回顾性分析我院2005年9月至2009年7月收治的65例颅内动脉瘤患者经显微外科治疗的临床资料.结果 65例患者共76个动脉瘤中:70个行瘤颈夹闭术、4个行动脉瘤包裹术、2个术中动脉瘤破裂.出院时按格拉斯哥结局量表(GOS)评定手术疗效:58例恢复良好、3例中度病残、2例重度病残、1例植物生存、1例死亡.结论 CT、MRI、计算机体层摄影血管成像(CTA)和数字减影血管造影(DSA)可为颅内动脉瘤的诊断提供重要的信息.显微手术夹闭是颅内动脉瘤的一种成熟、可靠和有效的治疗方法.早期手术能减少再出血,降低病死率和致残率.

  5. Cephalic vein aneurysm.

    Faraj, Walid; Selmo, Francesca; Hindi, Mia; Haddad, Fadi; Khalil, Ismail


    Cephalic vein aneurysms are rare malformations that may develop in any part of the vascular system, and their history, presentation, and management vary depending on their site. The etiology of venous aneurysms remains unclear, although several theories have been elaborated. Venous aneurysms are unusual vascular malformations that occur equally between the sexes and are seen at any age; they can present as either a painful or a painless subcutaneous mass. No serious complications have been reported from upper extremity venous aneurysms. Surgical excision is the definitive management for most of these. The case reported here presented with a painless and mobile, soft, subcutaneous mass that caused only cosmetic concern.

  6. Impact of intraoparetive parametres on survival of patients with ruptured abdominal aortic aneurysm

    Marković Miroslav


    Full Text Available Ruptured abdominal aortic aneurysm is one of the most urgent surgical conditions with high mortality that has not been changed in decades. Between 1991-2001 total number of 1058 patients was operated at the Institute for Cardiovascular Diseases of Clinical Center of Serbia due to abdominal aortic aneurysm. Of this number, 288 patients underwent urgent surgical repair because of ruptured abdominal aortic aneurysm. The aim of this retrospective study was to show results of the early outcome of surgical treatment of patients with ruptured abdominal aortic aneurysm, and to define relevant intraoperative factors that influence their survival. There were 83% male and 17% female patients in the study, mean aged 67 years. Mean duration of surgical procedure was 190 minutes (75-420 min. Most common localization of aneurysm was infrarenal - in 74% of patients, then juxtarenal (12.3%. Suprarenal aneurysm was found in 6.8% of patients, as well as thoracoabdominal aneurysm (6.8%. Retroperitoneal rupture of aortic aneurysm was most common - in 65% of patients, then intraperotineal in 26%. Rare finding such as chronic rupture was found in 3.8%, aortocaval fistula in 3.2% and aorto-duodenal fistula in 0.6% of patients. Mean aortic cross-clamping time was 41.7 minutes (10-150 min. Average intraoperative systolic pressure in patients was 106.5 mmHg (40-160 mmHg. Mean intraoperative blood loss was 3700 ml (1400-8500 ml. Mean intraoperative diuresis was 473 ml (0-2100 ml. Tubular graft was implanted in 53% of patients, aortoiliac bifurcated graft in 32.8%. Aortobifemoral reconstruction was done in 14.2% of patients. These data refer to the patients that survived surgical procedure. Intrahospital mortality that included intraoperative and postoperative deaths was 53.7%. Therefore, 46.3% patients survived surgical treatment and were released from the hospital. Intraoperative mortality was 13.5%. Type of aneurysm had no influence on outcome of patients (p>0.05, as

  7. Roux-en-Y Gastric Bypass Surgery Induces Early Plasma Metabolomic and Lipidomic Alterations in Humans Associated with Diabetes Remission.

    Tulika Arora

    Full Text Available Roux-en-Y gastric bypass (RYGB is an effective method to attain sustained weight loss and diabetes remission. We aimed to elucidate early changes in the plasma metabolome and lipidome after RYGB. Plasma samples from 16 insulin-resistant morbidly obese subjects, of whom 14 had diabetes, were subjected to global metabolomics and lipidomics analysis at pre-surgery and 4 and 42 days after RYGB. Metabolites and lipid species were compared between time points and between subjects who were in remission and not in remission from diabetes 2 years after surgery. We found that the variables that were most discriminatory between time points were decanoic acid and octanoic acid, which were elevated 42 days after surgery, and sphingomyelins (18:1/21:0 and 18:1/23:3, which were at their lowest level 42 days after surgery. Insulin levels were lower at 4 and 42 days after surgery compared with pre-surgery levels. At 4 days after surgery, insulin levels correlated positively with metabolites of branched chain and aromatic amino acid metabolism and negatively with triglycerides with long-chain fatty acids. Of the 14 subjects with diabetes prior to surgery, 7 were in remission 2 years after surgery. The subjects in remission displayed higher pre-surgery levels of tricarboxylic acid cycle intermediates and triglycerides with long-chain fatty acids compared with subjects not in remission. Thus, metabolic alterations are induced soon after surgery and subjects with diabetes remission differ in the metabolic profiles at pre- and early post-surgery time points compared to patients not in remission.

  8. Professor Peter Choyce: an early pioneer of intraocular lenses and corneal/refractive surgery.

    Pandey, Suresh K; Apple, David J


    Professor Peter Choyce, FRCS, DOMS, MS, was one of the pioneers of intraocular lens implant surgery. He developed an interest in artificial lens implantation following cataract surgery, a procedure that was widely criticized by the ophthalmic establishment in the UK, Europe, North America and other countries. Owing to the opposition to the intraocular lenses, Peter Choyce together with Sir Harold Ridley co-founded the International Intraocular Implant Club in 1966, which was responsible for the gradual acceptance of artificial lens implantation. Peter Choyce developed several models of intraocular lens, but did not patent the majority of them. The Choyce Mark IX, manufactured by Rayner Intraocular Lenses, became the first US Food and Drug Administration-approved intraocular lens in 1981. A review of Peter Choyce's record confirms a significant number of original innovations in the field of anterior segment surgery, including many procedures taken for granted today, but not associated with his name. These include early work on both kerato- and intraocular lens-refractive procedures, keratoprosthesis, pioneering paediatric implant procedures and others. Unfortunately his tenacious adherence to anterior chamber lens technology, while in general clinically sound, caused many to question his influence and hence he remained poorly understood even until after his death. He passed away on 8 August 2001 after a long fight with colon cancer. In this article, we provide evidence and elaborate Peter Choyce's accomplishments, which places him as one of the most innovative ophthalmologist in his surgical field in the twentieth century.

  9. Volumetry may predict early renal function after nephron sparing surgery in solitary kidney patients.

    Kuru, Timur H; Zhu, Jie; Popeneciu, Ionel V; Rudhardt, Nora S; Hadaschik, Boris A; Teber, Dogu; Roethke, Matthias; Hohenfellner, Markus; Zeier, Martin; Pahernik, Sascha A


    We investigate the impact of the residual kidney volume measured by tumor volumetry on preoperative imaging in predicting post-operative renal function. Nephron sparing surgery (NSS) in renal cell carcinoma (RCC) is the standard treatment for T1 kidney tumors. Resection of kidney tumors in solidary kidneys needs precise preoperative counseling of patients regarding post-operative renal function. Patients planned for renal tumor surgery who underwent prior nephrectomy on the contralateral side were included. We identified 35 patients in our database that underwent NSS in solitary kidneys and met the inclusion criteria. Tumor volumetry was performed on computer tomography (CT) or magnetic resonance imaging (MRI) with the Medical Imaging Interaction Toolkit (MITK). Clinical and pathological data were assessed. Follow-up data included renal function over 3 years. Mean age was 64 ± 8.1 years. Mean tumor volume on imaging was 27.5 ± 48.6 cc. Mean kidney volume was 195.2 ± 62.8 cc and mean residual kidney volume was 173.4 ± 65.3 cc. We found a correlation between renal function (MDRD) and residual kidney volume on imaging 1-week post-surgery (p = 0.038). Mid- and long-term renal function was not associated with residual kidney volume. In conclusion, renal volumetry may predict early renal function after NSS.

  10. Intraorbital ophthalmic artery aneurysm associated with basilar tip saccular aneurysm

    Dehdashti, A.R.; Tribolet, N. de [Department of Neurosurgery, HUG, Geneva (Switzerland); Safran, A.B. [Department of Ophthalmology, HUG, Geneva (Switzerland); Martin, J.B.; Ruefenacht, D.A. [Division of Neuroradiology, HUG, Geneva (Switzerland)


    We present a rare case of intraorbital ophthalmic artery aneurysm found incidentally, together with a ruptured aneurysm of the tip of the basilar artery. The intraorbital aneurysm was asymptomatic, and no treatment was offered. Angiographic control was recommended to detect any progression. Treatment may be indicated for documented enlargement or significant mass effect of the aneurysm. (orig.)

  11. Urinary biomarkers TIMP-2 and IGFBP7 early predict acute kidney injury after major surgery.

    Ivan Gocze

    Full Text Available To assess the ability of the urinary biomarkers IGFBP7 (insulin-like growth factor-binding protein 7 and TIMP-2 (tissue inhibitor of metalloproteinase 2 to early predict acute kidney injury (AKI in high-risk surgical patients.Postoperative AKI is associated with an increase in short and long-term mortality. Using IGFBP7 and TIMP-2 for early detection of cellular kidney injury, thus allowing the early initiation of renal protection measures, may represent a new concept of evaluating renal function.In this prospective study, urinary [TIMP-2]×[IGFBP7] was measured in surgical patients at high risk for AKI. A predefined cut-off value of [TIMP-2]×[IGFBP7] >0.3 was used for assessing diagnostic accuracy. Perioperative characteristics were evaluated, and ROC analyses as well as logistic regression models of risk assessment were calculated with and without a [TIMP-2]×[IGFBP7] test.107 patients were included in the study, of whom 45 (42% developed AKI. The highest median values of biomarker were detected in septic, transplant and patients after hepatic surgery (1.24 vs 0.45 vs 0.47 ng/l²/1000. The area under receiving operating characteristic curve (AUC for the risk of any AKI was 0.85, for early use of RRT 0.83 and for 28-day mortality 0.77. In a multivariable model with established perioperative risk factors, the [TIMP-2]×[IGFBP7] test was the strongest predictor of AKI and significantly improved the risk assessment (p<0.001.Urinary [TIMP-2]×[IGFBP7] test sufficiently detect patients with risk of AKI after major non-cardiac surgery. Due to its rapid responsiveness it extends the time frame for intervention to prevent development of AKI.

  12. Recurrent sigmoid volvulus - early resection may obviate later emergency surgery and reduce morbidity and mortality.

    Larkin, J O


    INTRODUCTION: Acute sigmoid volvulus is a well recognised cause of acute large bowel obstruction. PATIENTS AND METHODS: We reviewed our unit\\'s experience with non-operative and operative management of this condition. A total of 27 patients were treated for acute sigmoid volvulus between 1996 and 2006. In total, there were 62 separate hospital admissions. RESULTS: Eleven patients were managed with colonoscopic decompression alone. The overall mortality rate for non-operative management was 36.4% (4 of 11 patients). Fifteen patients had operative management (five semi-elective following decompression, 10 emergency). There was no mortality in the semi-elective cohort and one in the emergency surgery group. The overall mortality for surgery was 6% (1 of 15). Five of the seven patients managed with colonoscopic decompression alone who survived were subsequently re-admitted with sigmoid volvulus (a 71.4% recurrence rate). The six deaths in our overall series each occurred in patients with established gangrene of the bowel. With early surgical intervention before the onset of gangrene, however, good outcomes may be achieved, even in patients apparently unsuitable for elective surgery. Eight of the 15 operatively managed patients were considered to be ASA (American Society of Anesthesiologists) grade 4. There was no postoperative mortality in this group. CONCLUSIONS: Given the high rate of recurrence of sigmoid volvulus after initial successful non-operative management and the attendant risks of mortality from gangrenous bowel developing with a subsequent volvulus, it is our contention that all patients should be considered for definitive surgery after initial colonoscopic decompression, irrespective of the ASA score.

  13. The fate of facial asymmetry after surgery for "muscular torticollis" in early childhood

    Dinesh Kittur


    Full Text Available Aims and Objectives: To study wheather the facial features return to normal after surgery for muscular torticollis done in early childhood. Materials and Methods: This is a long-term study of the fate of facial asymmetry in four children who have undergone operation for muscular torticollis in early childhood. All the patients presented late, i.e., after the age of 4 years with a scarred sternomastoid and plagiocephaly, so conservative management with physiotherapy was not considered. All the patients had an x-ray of cervical spine and eye and dental checkup before making a diagnosis of muscular torticollis. Preoperative photograph of the patient′s face was taken to counsel the parents about the secondary effect of short sternomastoid on facial features and the need for surgery. After division of sternomastoid muscle and release of cervical fascia when indicated, the head was maintained in a hyperextended position supported by sand bags for three days. Gradual physiotherapy was then started followed by wearing of a Minerva collar that the child wore for a maximum period of time in 24 h. Physiotherapy was continued three times a day till the range of movements of the head returned to normal. During the follow-up, serial photographs were taken to note the changes in the facial features. Results: In all four patients, the asymmetry of the face got corrected and the facial features returned to normal. Conclusion: Most of the deformity of facial asymmetry gets corrected in the first two years after surgery. By adolescence, the face returns to normal.

  14. Laparoscopic single port surgery in children using Triport: our early experience.

    de Armas, Ismael A Salas; Garcia, Isabella; Pimpalwar, Ashwin


    Laparoscopy has become the gold standard technique for appendectomy and cholecystectomy. With the emergence of newer laparoscopic instruments which are roticulating and provide 7 degrees of freedom it is now possible to perform these operations through a single umbilical incision rather than the standard 3-4 incisions and thus lead to more desirable cosmetic results and less postoperative pain. The newer reticulating telescopes provide excellent exposure of the operating field and allow the operations to proceed routinely. Recently, ports [Triports (Olympus surgery)/SILS ports] especially designed for single incision laparoscopic surgery (SILS) have been developed. We herein describe our experience with laparoscopic single port appendectomies and cholecystectomies in children using the Triport. This is a retrospective cohort study of children who underwent single incision laparoscopic surgery between May 2009 and August 2010 at Texas Children's Hospital and Ben Taub General Hospital in Houston Texas by a single surgeon. Charts were reviewed for demographics, type of procedure, operative time, early or late complications, outcome and cosmetic results. Fifty-four patients underwent SILS. A total of 50 appendectomies (early or perforated) and 4 cholecystectomies were performed using this new minimally invasive approach. The average operative time for SILS/LESS appendectomy was 54 min with a range between 25 and 205 min, while operative time for SILS cholecystectomy was 156 min with a range of 75-196 min. Only small percentage (4%) of appendectomies (mostly complicated) were converted to standard laparoscopy, but none were converted to open procedure. All patients were followed up in the clinic after 3-4 weeks. No complications were noted and all patients had excellent cosmetic results. Parents were extremely satisfied with the cosmetic results. SILS/LESS is a safe, minimally invasive approach for appendectomy and cholecystectomy in children. This new approach is

  16. Endovascular coil embolization for recurrence of intracranial aneurysms more than 10 years after clipping

    Naoya Takeda


    Full Text Available We report three cases of endovascular coil embolization for recurrent cerebral aneurysm after neck clipping more than 10 years previously. In two cases, their first subarachnoid hemorrhage was treated in other hospitals and the details of follow-up after discharge were unknown. After their second subarachnoid hemorrhage recurred 15 and 30 years, respectively. The remaining patient, who was treated in our center, was followed by magnetic resonance imaging 5 years after surgery but since then she didn′t go to our center. She came to our center for follow-up examination 10 years after the first surgery. The digital subtraction angiography showed recurrence of clipped aneurysms in all patients. All of them underwent endovascular coil embolization and total obliteration of the aneurysms without complications related to the procedures. Endovascular coil embolization is an alternative modality to direct surgery for cerebral aneurysms, especially for recurrence after clipping. Endovascular coil embolization of residual aneurysms after surgery may be the treatment of choice because of the difficulties in second direct surgery. We conclude that it is necessary to perform follow-up evaluations after surgery, even if the complete obliteration of aneurysms is performed. Current medical literature does not provide recommendations for the duration of follow-up after aneurysm clipping. The authors suggest that this period perhaps be at least a decade.

    To determine whether a collaborative learning strategy-derived clinical practice guideline can reduce the duration of endotracheal intubation following infant heart surgery. Prospective and retrospective data collected from the Pediatric Heart Network in the 12 months pre- and post-clinical practice guideline implementation at the four sites participating in the collaborative (active sites) compared with data from five Pediatric Heart Network centers not participating in collaborative learning (control sites). Ten children's hospitals. Data were collected for infants following two-index operations: 1) repair of isolated coarctation of the aorta (birth to 365 d) and 2) repair of tetralogy of Fallot (29-365 d). There were 240 subjects eligible for the clinical practice guideline at active sites and 259 subjects at control sites. Development and application of early extubation clinical practice guideline. After clinical practice guideline implementation, the rate of early extubation at active sites increased significantly from 11.7% to 66.9% (p collaborative learning strategy designed clinical practice guideline significantly increased the rate of early extubation with no change in the rate of reintubation. The early extubation clinical practice guideline did not significantly change postoperative ICU length of stay.

    Few reports have focused on treatment of adult cervical deformity (ACD). To present early complication rates associated with ACD surgery. A prospective multicenter database of consecutive operative ACD patients was reviewed for early (≤30 days from surgery) complications. Enrollment required at least 1 of the following: cervical kyphosis >10 degrees, cervical scoliosis >10 degrees, C2-7 sagittal vertical axis >4 cm, or chin-brow vertical angle >25 degrees. Seventy-eight patients underwent surgical treatment for ACD (mean age, 60.8 years). Surgical approaches included anterior-only (14%), posterior-only (49%), anterior-posterior (35%), and posterior-anterior-posterior (3%). Mean numbers of fused anterior and posterior vertebral levels were 4.7 and 9.4, respectively. A total of 52 early complications were reported, including 26 minor and 26 major. Twenty-two (28.2%) patients had at least 1 minor complication, and 19 (24.4%) had at least 1 major complication. Overall, 34 (43.6%) patients had at least 1 complication. The most common complications included dysphagia (11.5%), deep wound infection (6.4%), new C5 motor deficit (6.4%), and respiratory failure (5.1%). One (1.3%) mortality occurred. Early complication rates differed significantly by surgical approach: anterior-only (27.3%), posterior-only (68.4%), and anterior-posterior/posterior-anterior-posterior (79.3%) (P = .007). This report provides benchmark rates for overall and specific ACD surgery complications. Although the surgical approach(es) used were likely driven by the type and complexity of deformity, there were significantly higher complication rates associated with combined and posterior-only approaches compared with anterior-only approaches. These findings may prove useful in treatment planning, patient counseling, and ongoing efforts to improve safety of care. 3CO, 3-column osteotomiesACD, adult cervical deformityEBL, estimated blood lossISSG, International Spine Study groupSVA, sagittal vertical axis.

  3. [Per os early nutrition for colorectal pathology susceptible of laparoscopy-assisted surgery].

    Fernández de Bustos, A; Creus Costas, G; Pujol Gebelli, J; Virgili Casas, N; Pita Mercé, A M


    Current less invasive surgical techniques, the use of new analgesic and anesthetic drugs, and early mobilization ("multimodal surgical strategies") reduce the occurrence of post-surgery paralytic ileus and vomiting, making possible early nutrition by the digestive route. With these premises, a nutrition protocol was designed for its implementation in colorectal pathology susceptible of laparoscopy-assisted surgery. to assess the efficacy of this protocol that comprises 3 phases. Phase I: home preparation with 7 days duration; low-residues and insoluble fiber diet, supplemented with 400 mL of hyperproteic polymeric formula with no lactose or fiber, bowel cleansing 2 days prior to surgery and hydration with water, sugared infusions, and vegetable broth. Phase II: immediate post-surgical period with watery diet for 3 days with polymeric diet with no fiber. Phase III: semi-solid diet with no residues, nutritional formula and progressive reintroduction of food intake in four stages of varying duration according to surgery and digestive tolerance. prospective study performed at our hospital with patients from our influence area, from February 2003 to May 2004, including 25 patients, 19 men and 6 women, with mean age of 63.3 years (range = 33-79) and mean body mass index of 26.25 kg/m2 (range = 20.84-31.3), all of them suffering from colorectal pathology susceptible of laparoscopy-assisted surgery, and to which the study protocol was applied. Fourteen left hemicolectomies, 5 right hemicolectomies, 4 low anterior resections with protective colostomy, and subtotal colectomies and lateral ileostomy were done. Final diagnoses were: 3 diverticular diseases; 3 adenomas; 7 rectosigmoidal neoplasms; and 12 large bowel neoplasms in other locations. The pathology study confirmed: pT3N0 (n = 7), pT3N1 (n = 3), pT3N2 (n = 1), and pT3N1M1 (n = 1), pT1N0 (n = 4), pT1N1 (n = 2), pTis (n = 1). Twelve patients were started on adjuvant therapy of which 3 had received an initial treatment

    Abstract Recently, a few studies have raised the question of whether preoperative chemoradiotherapy (PCRT) is essential for all T3 rectal cancers. This case-matched study aimed to compare the long-term outcomes of surgery alone with those of PCRT + surgery for magnetic resonance imaging (MRI)-assessed T3ab (extramural depth of invasion ≤5 mm) and absent mesorectal fascia invasion (clear MRF) in mid/lower rectal cancer patients. From January 2006 to November 2012, 203 patients who underwent curative surgery alone (n = 118) or PCRT + surgery (n = 85) were enrolled in this retrospective study. A 1:1 propensity score-matched analysis was performed to eliminate the inherent bias. Case-matching covariates included age, sex, body mass index, histologic grade, carcinoembryonic antigen, operation method, follow-up period, tumor height, and status of lymph node metastasis. The end-points were the 5-year local recurrence (LR) rate and disease-free-survival (DFS). After propensity score matching, 140 patients in 70 pairs were included. Neither the 5-year LR rate nor the DFS was significantly different between the 2 groups (the 5-year LR rate, P = 0.93; the 5-year DFS, P = 0.94). The 5-year LR rate of the surgery alone was 2% (95% confidence interval [CI] 0.2%–10.9%) versus 2% (95% CI 0.2%–10.1%) in the PCRT + surgery group. The 5-year DFS of the surgery alone was 87% (95% CI 74.6%–93.7%) versus 88% (95% CI 77.8%–93.9%) in the PCRT + surgery group. In patients with MRI-assessed T3ab and clear MRF mid/lower rectal cancer, the long-term outcomes of surgery alone were comparable with those of the PCRT + surgery. The suggested MRI-assessed T3ab and clear MRF can be used as a highly selective indication of surgery alone in mid/lower T3 rectal cancer. Additionally, in those patients, surgery alone can be tailored to the clinical situation. PMID:28328820

  5. Pediatric intracranial aneurysms: new and enlarging aneurysms after index aneurysm treatment or observation.

    Hetts, S W; English, J D; Dowd, C F; Higashida, R T; Scanlon, J T; Halbach, V V


    Children with brain aneurysms may be at higher risk than adults to develop new or enlarging aneurysms in a relatively short time. We sought to identify comorbidities and angiographic features in children that predict new aneurysm formation or enlargement of untreated aneurysms. Retrospective analysis of the University of California-San Francisco Pediatric Aneurysm Cohort data base including medical records and imaging studies was performed. Of 83 patients harboring 114 intracranial aneurysms not associated with brain arteriovenous malformations or intracranial arteriovenous fistulas, 9 (8.4%) developed new or enlarging brain aneurysms an average of 4.2 years after initial presentation. Comorbidities that may be related to aneurysm formation were significantly higher in patients who developed new aneurysms (89%) as opposed to patients who did not develop new or enlarging aneurysms (41%; RR, 9.5; 95% CI, 1.9%-48%; P = .0099). Patients with multiple aneurysms at initial presentation were more likely than patients with a single aneurysm at presentation to develop a new or enlarging aneurysm (RR, 6.2; 95% CI, 2.1%-185; P = .0058). Patients who initially presented with at least 1 fusiform aneurysm were more likely to develop a new or enlarging aneurysm than patients who did not present with a fusiform aneurysm (RR, 22; 95% CI, 3.6%-68%; P = .00050). Index aneurysm treatment with parent artery occlusion also was associated with higher risk of new aneurysm formation (RR, 4.2; 95% CI, 1.3%-13%; P = .024). New aneurysms did not necessarily arise near index aneurysms. The only fatality in the series was due to subarachnoid hemorrhage from a new posterior circulation aneurysm arising 20 months after index anterior circulation aneurysm treatment in an immunosuppressed patient. Patients who presented with a fusiform aneurysm had a significantly greater incidence of developing a new aneurysm or enlargement of an index aneurysm than did those who presented with a saccular aneurysm

  7. Glutathione system participation in thoracic aneurysms from patients with Marfan syndrome.

    Zúñiga-Muñoz, Alejandra María; Pérez-Torres, Israel; Guarner-Lans, Verónica; Núñez-Garrido, Elías; Velázquez Espejel, Rodrigo; Huesca-Gómez, Claudia; Gamboa-Ávila, Ricardo; Soto, María Elena


    Aortic dilatation in Marfan syndrome (MFS) is progressive. It is associated with oxidative stress and endothelial dysfunction that contribute to the early acute dissection of the vessel and can result in rupture of the aorta and sudden death. We evaluated the participation of the glutathione (GSH) system, which could be involved in the mechanisms that promote the formation and progression of the aortic aneurysms in MFS patients. Aortic aneurysm tissue was obtained during chest surgery from eight control subjects and 14 MFS patients. Spectrophotometrical determination of activity of glutathione peroxidase (GPx), glutathione-S-transferase (GST), glutathione reductase (GR), lipid peroxidation (LPO) index, carbonylation, total antioxidant capacity (TAC), and concentration of reduced and oxidized glutathione (GSH and GSSG respectively), was performed in the homogenate from aortic aneurysm tissue. LPO index, carbonylation, TGF-β1, and GR activity were increased in MFS patients (p < 0.04), while TAC, GSH/GSSG ratio, GPx, and GST activity were significantly decreased (p < 0.04). The depletion of GSH, in spite of the elevated activity of GR, not only diminished the activity of GSH-depend GST and GPx, but increased LPO, carbonylation and decreased TAC. These changes could promote the structural and functional alterations in the thoracic aorta of MFS patients.

  8. Aneurysm and Neurocysticercosis: Casual or Causal Relationship? Case Report and Review of the Literature

    Svetlana Agapejev


    Full Text Available Four cases of suggestive inflammatory aneurysms in patients with neurocysticercosis have been described. We report a case of a 49-year-old woman who presented with subarachnoid haemorrhage from a right middle cerebral artery bifurcation aneurysm and had a casual relationship with neurocysticercosis. At surgery, a viable cysticercus without signs of inflammation or thickened leptomeninges was found in the distal position of the aneurysm. Postoperatively, the patient received albendazole and dextrochlorpheniramine. In the subsequent three years, the patient was asymptomatic and took drugs to prevent convulsion and arterial hypertension. The relationship between NCC and the presence of cerebral aneurysm is discussed.

  9. Mouth and genital ulcers with inflamed cartilage (MAGIC) syndrome complicated by aneurysmal aortitis.

    Ng, Chin Soon; Hogan, Patrick; McKenzie, Scott; Gibbs, Harry; Strutton, Geoff; Wong, Richard


    "MAGIC syndrome" (Mouth And Genital ulcers with Inflamed Cartilage) has been proposed to describe patients with clinical features of both relapsing polychondritis and Behcet disease. A total of 18 cases have been reported with only 1 case associated with aneurysmal aortitis described in 1997. Herein, we describe a patient with MAGIC syndrome complicated by aneurysmal aortitis requiring cardiothoracic surgery and intensive immunosuppression. Monitoring for the possible development of inflammatory aortic aneurysms should thus be considered in patients with MAGIC syndrome who have persistently elevated serum inflammatory markers. If an aortic aneurysm is detected, cardiothoracic surgical referral is necessary, close monitoring for enlargement is mandatory, and intensification of immunosuppressive therapy should be considered.

    Gustavo Alves Schaitza


    Full Text Available An aneurysm of the left ventricle is a complication of acute myocardial infarction. We report a case of a giant aneurysm of the left ventricle after myocardial infarction in a 59 year-old male patient. The surgery to correct the aneurysm was performed with the use of cardiopulmonary bypass under normothermia. A bovine pericardial patch was used for the geometric reconstruction of the ventricular wall affected by the aneurysm. After the procedure, echocardiography and magnetic resonance imaging revealed improvement in left ventricular ejection fraction and volume reduction.

    Egnor, M R; Page, L K; David, C

    A 15-year-old drummer in a neighborhood rock music band suffered a traumatic true aneurysm of the cervical vertebral artery from violent head and neck motion. He underwent excision of the aneurysm after distal and proximal ligation of the artery. He is neurologically normal 1 year after surgery. The mechanisms of injury caused by extremes of cervical motion, as well as 5 previously reported cases of extracranial vertebral artery aneurysm from closed trauma, are discussed. Excision of vertebral artery aneurysms in patients with emboli from a mural thrombus is recommended. The consequences of vertebral artery ligation and the indications for distal reconstruction are discussed.

The presentation, the diagnostic evaluation, and the surgical management of the aneurysm are discussed.

  15. Surgical management of unruptured posterior carotid artery wall aneurysms.

    O'Shaughnessy, Brian A; Getch, Christopher C; Bendok, Bernard R; Batjer, H Hunt


    Intracranial aneurysms arising from the posterior wall of the supraclinoid carotid artery are extremely common lesions. The aneurysm dilation typically occurs in immediate proximity to the origin of the posterior communicating artery and, less commonly, the anterior choroidal artery (AChA). Because of the increasingly widespread use of noninvasive neuroimaging methods to evaluate patients believed to harbor cerebral lesions, many of these carotid artery aneurysms are now documented in their unruptured state, prior to occurrence of subarachnoid hemorrhage. Based on these factors, the management of unruptured posterior carotid artery (PCA) wall aneurysms is an important element of any neurosurgical practice. Despite impressive recent advances in endovascular therapy, the placement of microsurgical clips to exclude aneurysms with preservation of all afferent and efferent vasculature remains the most efficacious and durable therapy. To date, an optimal outcome is only achieved when the neurosurgeon is able to combine systematic preoperative neurovascular assessment with meticulous operative technique. In this report, the authors review their surgical approach to PCA wall aneurysms, which is greatly based on the extensive neurovascular experience of the senior author. Focus is placed on their methods of preoperative evaluation and operative technique, with emphasis on neurovascular anatomy and the significance of oculomotor nerve compression. They conclude by discussing surgery-related complications, with a particular focus on intraoperative rupture of aneurysms and their management, and the postoperative ischemic AChA syndrome.

  17. Costs and quality of life for prehabilitation and early rehabilitation after surgery of the lumbar spine

    Andreasen Jakob


    Full Text Available Abstract During the recent years improved operation techniques and administrative procedures have been developed for early rehabilitation. At the same time preoperative lifestyle intervention (prehabilitation has revealed a large potential for additional risk reduction. The aim was to assess the quality of life and to estimate the cost-effectiveness of standard care versus an integrated programme including prehabilitation and early rehabilitation. Methods The analyses were based on the results from 60 patients undergoing lumbar fusion for degenerative lumbar disease; 28 patients were randomised to the integrated programme and 32 to the standard care programme. Data on cost and health related quality of life was collected preoperatively, during hospitalisation and postoperatively. The cost was estimated from multiplication of the resource consumption and price per unit. Results Overall there was no difference in health related quality of life scores. The patients from the integrated programme obtained their postoperative milestones sooner, returned to work and soaked less primary care after discharge. The integrated programme was 1,625€ (direct costs 494€ + indirect costs 1,131€ less costly per patient compared to the standard care programme. Conclusion The integrated programme of prehabilitation and early rehabilitation in spine surgery is more cost-effective compared to standard care programme alone.

  19. Endoscope-assisted microneurosurgery for intracranial aneurysms

    Renato Juan Galzio


    Full Text Available Background:The endovascular techniques has widely changed the treatment of intracranial aneurysms.However surgery still represent the best therapeutic option in case of broad-based and complex lesions.The combined use of endoscopic and microsurgical techniques (EAM may improve surgical results. Objective:The purpose of our study is to evaluate the advantages and limits of EAM for intracranial aneurysms.Methods:Between January 2002 and December 2012,173 patients,harbouring 206 aneurysms were surgically treated in our department with the EAM technique.157 aneurysms were located in the anterior circulation and 49 were in the posterior circulation.Standard tailored approaches,based on skull base surgery principles,were chosen.The use of the endoscope included three steps:initial inspection,true operative time and final inspection.For each procedure,an intraoperative video and an evaluation schedule were prepared,to report surgeons’ opinions about the technique itself.In the first cases,we always used the endoscope during surgical procedures in order to get an adequate surgical training.Afterwards we became aware in selecting cases in which to apply the endoscopy,as we started to become familiar with its advantages and limits.Results:After clipping,all patients were undergone postoperative cerebral angiography.No surgical mortality related to EAM were observed.Complications directly related to endoscopic procedures were rare.Conclusions:Our retrospective study suggests that endoscopic efficacy for aneurysms is only scarcely influenced by the preoperative clinical condition (Hunt-Hess grade,surgical timing,presence of blood in the cisterns (Fisher grade and/or hydrocephalus.However the most important factors contributing to the efficacy of EAM are determined by the anatomical locations and sizes of the lesions.Furthermore,the advantages are especially evident using dedicated scopes and holders,after an adequate surgical training to increase the

    Abdullah Jibawi


    Full Text Available Background. The coexistence of neoplasm and abdominal aortic aneurysm (AAA presents a real management challenge. This paper reviews the literature on the prevalence, diagnosis, and management dilemmas of concurrent visceral malignancy and abdominal aortic aneurysm. Method. The MEDLINE and HIGHWIRE databases (1966-present were searched. Papers detailing relevant data were assessed for quality and validity. All case series, review articles, and references of such articles were searched for additional relevant papers. Results. Current challenges in decision making, the effect of major body-cavity surgery on an untreated aneurysm, the effects of major vascular surgery on the treatment of malignancy, the use of EVAR (endovascular aortic aneurysm repair as a fairly low-risk procedure and its role in the management of malignancy, and the effect of other challenging issues such as the use of adjuvant therapy, and patients informed decision-making were reviewed and discussed. Conclusion. In synchronous malignancy and abdominal aortic aneurysm, the most life-threatening lesion should be addressed first. Endovascular aneurysm repair where possible, followed by malignancy resection, is becoming the preferred initial treatment choice in most centres.

  1. Hemodynamic challenge to early mobilization after cardiac surgery: A pilot study

    Tiziano Cassina


    Full Text Available Background: Active mobilization is a key component in fast-track surgical strategies. Following major surgery, clinicians are often reluctant to mobilize patients arguing that circulatory homeostasis would be impaired as a result of myocardial stunning, fluid shift, and autonomic dysfunction. Aims: We examined the feasibility and safety of a mobilization protocol 12-24 h after elective cardiac surgery. Setting and Design: This observational study was performed in a tertiary nonacademic cardiovascular Intensive Care Unit. Materials and Methods: Over a 6-month period, we prospectively evaluated the hemodynamic response to a two-staged mobilization procedure in 53 consecutive patients. Before, during, and after the mobilization, hemodynamics parameters were recorded, including the central venous oxygen saturation (ScvO 2 , lactate concentrations, mean arterial pressure (MAP, heart rate (HR, right atrial pressure (RAP, and arterial oxygen saturation (SpO 2 . Any adverse events were documented. Results: All patients successfully completed the mobilization procedure. Compared with the supine position, mobilization induced significant increases in arterial lactate (34.6% [31.6%, 47.6%], P = 0.0022 along with reduction in RAP (−33% [−21%, −45%], P 10% and nine of them (17% required treatment. Hypotensive patients experienced a greater decrease in ScvO 2 (−18 ± 5% vs. −9 ± 4%, P = 0.004 with similar changes in RAP and HR. All hemodynamic parameters, but arterial lactate, recovered baseline values after resuming the horizontal position. Conclusions: Early mobilization after cardiac surgery appears to be a safe procedure as far as it is performed under close hemodynamic and clinical monitoring in an intensive care setting.

  2. Detection of the early keratoconus based on corneal biomechanical properties in the refractive surgery candidates

    Zofia Pniakowska


    Full Text Available Context: Subclinical keratoconus is contraindication to refractive surgery. The currently used methods of preoperative screening do not always allow differentiating between healthy eyes and those with subclinical keratoconus. Aim: To evaluate biomechanical parameters of the cornea, waveform score (WS, and intraocular pressure (IOP as potentially useful adjuncts to the diagnostic algorithm for precise detection of the early keratoconus stages and selection of refractive surgery candidates. Settings and Design: Department of Ophthalmology and prospective cross-sectional study. Patients and Methods: Patients enrolled in the study were diagnosed with refractive disorders. We assessed parameters of corneal biomechanics such as corneal hysteresis (CH, corneal resistance factor (CRF, Goldman-correlated IOP (IOPg, corneal compensated IOP, WS, and keratoconus match index (KMI. They were classified into one of three groups based on the predefined KMI range: Group 1 (from 0.352 to 0.757 – 45 eyes, Group 2 (from −0.08 to 0.313 – 52 eyes, and Group 0 - control group (from 0.761 to 1.642 – 80 eyes. Results: In both study groups, IOPg, CRF, and CH were decreased when compared to control (P < 0.0001. In control group, there was positive correlation between CH and KMI (P < 0.05, with no correlations in any of the two study groups. CRF correlated positively with KMI in control (P < 0.0001 and in Group 2 (P < 0.05. Conclusions: CH and CRF, together with WS and IOPg, consist a clinically useful adjunct to detect subclinical keratoconus in patients referred for refractive surgery when based on KMI staging.

    To investigate the efficacy of thrombomodulin (TM)-α for treatment of disseminated intravascular coagulopathy (DIC) in the field of gastrointestinal surgery. Thirty-six peri-operative DIC patients in the field of gastrointestinal surgery who were treated with TM-α were retrospectively investigated. The relationships between patient demographics and the efficacy of TM-α were examined. Analysis of survival at 28 d was also performed on some parameters by means of the Kaplan-Meier method. Relationships between the initiation of TM-α and patient demographics were also evaluated. Abscess formation or bacteremia was the most frequent cause of DIC (33%), followed by digestive tract perforation (31%). Twenty-six patients developed DIC after surgery, frequently within 1 wk (81%). TM-α was most often administered within 1 d of the DIC diagnosis (72%) and was continued for more than 3 d (64%). Although bleeding tendency was observed in 7 patients (19%), a hemostatic procedure was not needed. DIC scores, systemic inflammatory response syndrome (SIRS) scores, quick-sequential organ failure assessment (qSOFA) scores, platelet counts, and prothrombin time ratios significantly improved after 1 wk (P SIRS and qSOFA) at 1 wk were significantly better prognostic factors for 28-d survival (P < 0.05, for all). TM-α was administered significantly earlier to patients with severe clinical symptoms, such as high qSOFA scores, sepsis, shock or high lactate values (P < 0.05, for all). Early administration of TM-α and improvements in each parameter were essential for treatment of DIC. The diagnosis of patients with mild symptoms requires further study.

  4. Role of surgery in colorectal liver metastases: too early or too late?

    Dimitroulis, Dimitrios; Nikiteas, Nikolaos; Troupis, Theodore; Patsouras, Dimitrios; Skandalakis, Panayiotis; Kouraklis, Gregory


    As colorectal cancer and colorectal liver metastases become a serious public health problem, new treatment modalities are needed in order to achieve better results. In the last decade there has been very important progress in oncology, with new and more effective chemotherapeutic agents administered alone or in combination improving the resectability rate in up to 40% of patients with colorectal liver metastases. Advances in interventional radiology, in particular, with the use of portal vein embolization and radiofrequency thermal ablation are new strategies allowing major liver resections and treatment of small liver metastases or early recurrences. Surgery, however, remains the gold standard strategy with intention to treat. In this review article we will describe the advanced role of surgery in the multidisciplinary approach to colorectal liver metastases, and the clinical problems the liver surgeon has to deal with, such as the resectability of the metastases, the presence of bilobar liver lesions and extrahepatic disease, the impact of chemotherapy in already resectable liver metastases, the problem of vanishing metastases after chemotherapy and the dilemma of staged or combined liver and colon operations and which organ first in the clinical scenario of synchronous colorectal liver metastases.

  5. Early Functional Treatment and Modern Cast Making for Indications in Hand Surgery

    S. Bohr


    Full Text Available Cast treatment can serve both as a nonsurgical treatment option and as a means for providing postoperative protection. However, with the duration of immobilization intervals, the benefits of cast treatment, especially in hand surgery, are at risk of being outweighed by undesired drawbacks such as joint stiffening and contracture formation. In order to minimize potential complications commonly associated with cast treatment, efforts to further improve cast making must attempt to reconcile two conflicting objectives: (1 to achieve stability and rigidity at the site of injury (e.g., fracture retention and (2 to allow free range of joint movement as early as possible. In addition, in order to assure patient compliance, modern cast treatments should aim to improve wearing-comfort of the cast. This paper describes modern cast designs for four common types hand injuries, with sample cases highlighting the clinical outcome of each treatment.

  7. Early goal-directed therapy in moderate to high-risk cardiac surgery patients

    Kapoor Poonam


    Full Text Available Early goal-directed therapy is a term used to describe the guidance of intravenous fluid and vasopressor/inotropic therapy by using cardiac output or similar parameters in the immediate post-cardiopulmonary bypass in cardiac surgery patients. Early recognition and therapy during this period may result in better outcome. In keeping with this aim in the cardiac surgery patients, we conducted the present study. The study included 30 patients of both sexes, with EuroSCORE ≥3 undergoing coronary artery bypass surgery under cardiopulmonary bypass. The patients were randomly divided into two groups, namely, control and early goal-directed therapy (EGDT groups. All the subjects received standardized care; arterial pressure was monitored through radial artery, central venous pressure through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour and frequent arterial blood gas analysis. In addition, cardiac index monitoring using FloTrac™ and continuous central venous oxygen saturation using PreSep™ was used in patients in the EGTD group. Our aim was to maintain the cardiac index at 2.5-4.2 l/min/m 2 , stroke volume index 30-65 ml/beat/m 2 , systemic vascular resistance index 1500-2500 dynes/s/cm 5 /m 2 , oxygen delivery index 450-600 ml/min/m 2 , continuous central venous oximetry more than 70%, stroke volume variation less than 10%; in addition to the control group parameters such as central venous pressure 6-8 mmHg, mean arterial pressure 90-105 mmHg, normal arterial blood gas analysis values, pulse oximetry, hematocrit value above 30% and urine output more than 1 ml/kg/h. The aims were achieved by altering the administration of intravenous fluids and doses of inotropic or vasodilator agents. Three patients were excluded from the study and the data of 27 patients analyzed. The extra volume used (330 ± 160 v/s 80 ± 80 ml, P = 0.043 number of adjustments of inotropic agents (3

  8. Combined Surgical and Endovascular Management of a Giant Fusiform PCA Aneurysm in a Pediatric Patient

    Shin, S.H.; Choi, I.S.; Thomas, K.; David, C.A.


    Summary Treatment of intracranial giant aneurysms presents is challenging. In the case of pediatric giant aneurysm, more challenges arise. We describe our experience with a 17-year-old pediatric patient who presented with severe headache. She was diagnosed as having a giant fusiform aneurysm at the right P1-P2-Pcom junction. The aneurysm was treated with superficial temporal artery-posterior cerebral artery bypass and subsequent coil embolization of the aneurysm with parent artery occlusion. The patient had an excellent outcome at one-year follow-up. Our case suggests a combined approach of surgical and endovascular management may yield a better outcome than surgery or endovascular management alone in the treatment of pediatric giant aneurysm.

  9. Recurrent Sudden Sensorineural Hearing Loss in a Patient with Aortic Aneurysm

    Mehmet Kilickaya


    Full Text Available Etiologies of sudden sensorineural hearing loss (SSNHL include factors such as viral infections, embolism, aneurysm and vascular events. A 63-year-old male patient with a history of hypertension and aortic aneurysm surgery referred to our clinic with complaints of sensorineural hearing loss. The patient fully recovered after medical treatment. He had another SSNHL attack three months later; the examinations revealed that the recurrence of the patient%u2019s aortic aneurysms, which suggested that the etiology might be the microembolism associated with aneurysm in that case. We did not consider hyperbaric oxygen treatment (HBOT an option because it posed a relative risk for the patient. Additionally, as the patient underwent an operation primarily for aneurysm, the SSNHL treatment was interrupted, which resulted in permanent hearing loss. In conclusion, aortic aneurysm is a serious disease that may result in SSNHL, and might affect therapeutic options for this disease.

  10. True digital artery aneurysm of the third finger: a case report and literature review

    Yuksel Kankaya


    Full Text Available True aneurysms of the digital artery are very rare. Sixteen cases of true digital artery aneurysms have been reported in English literature since 1982. We present a true aneurysm of the digital artery of the third finger which is the largest aneurysm have been reported so far. In operation, the third finger ulnar digital artery aneurysm was clamped and excised. Reconstruction was performed with an inter positional vein graft. At follow-up 12 months after surgery, the patient had no pain or swelling in the third finger. In this study, we aimed to present an extremely rare case of a digital artery aneurysm that reached a large size rapidly. [Hand Microsurg 2012; 1(2.000: 68-71

  11. Acute retroperitoneal bleeding due to inferior mesenteric artery aneurysm: Case report

    Ferrón JA


    Full Text Available Abstract Background Visceral artery aneurysms (VAA, although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA and celiac trunk, successfully treated with surgery. Methods A 65-year-old man presented with abdominal pain and hypovolemic shock. Abdominal CT scan showed an aneurysm of the inferior mesenteric artery with retroperitoneal hematoma. In addition, an obstructive disease of the superior mesenteric artery and celiac axis was observed. Results Upon emergency laparotomy a ruptured inferior mesenteric artery aneurysm was detected. The aneurysm was excised and the artery reconstructed by end-to-end anastomosis. Conclusions This report discusses the etiology, presentation, diagnosis and case management of inferior mesenteric artery aneurysms.

  12. Early detection of changes in lung mechanics with oscillometry following bariatric surgery in severe obesity.

    Peters, Ubong; Hernandez, Paul; Dechman, Gail; Ellsmere, James; Maksym, Geoffrey


    Obesity is associated with respiratory symptoms that are reported to improve with weight loss, but this is poorly reflected in spirometry, and few studies have measured respiratory mechanics with oscillometry. We investigated whether early changes in lung mechanics following weight loss are detectable with oscillometry. Furthermore, we investigated whether the changes in lung mechanics measured in the supine position following weight loss are associated with changes in sleep quality. Nineteen severely obese female subjects (mean body mass index, 47.2 ± 6.6 kg/m(2)) were evaluated using spirometry, oscillometry, plethysmography, and the Pittsburgh Sleep Quality Index before and 5 weeks after bariatric surgery. These tests were conducted in both the upright and the supine position, and pre- and postbronchodilation with 200 μg of salbutamol. Five weeks after surgery, weight loss of 11.5 ± 2.5 kg was not associated with changes in spirometry and plethysmography, with the exception of functional residual capacity. There were also no changes in upright respiratory system resistance (Rrs) or reactance following weight loss. Importantly, however, in the supine position, weight loss caused a substantial reduction in Rrs. In addition, sleep quality improved significantly and was highly correlated with the reduction in supine Rrs. Prior to weight loss, subjects did not respond to the bronchodilator when assessed in the upright position with either spirometry or oscillometry; however, with modest weight loss, bronchodilator responsiveness returned to the normal range. Improvements in lung mechanics occur very early after weight loss, mostly in the supine position, resulting in improved sleep quality. These improvements are detectable with oscillometry but not with spirometry.

  13. Cardiac catheterization in the early post-operative period after congenital cardiac surgery.

    Nicholson, George T; Kim, Dennis W; Vincent, Robert N; Kogon, Brian E; Miller, Bruce E; Petit, Christopher J


    This study sought to demonstrate that early cardiac catheterization, whether used solely as a diagnostic modality or for the use of transcatheter interventional techniques, can be used effectively and with an acceptable risk in the post-operative period. Cardiac catheterization offers important treatment for patients with congenital heart disease. Early post-operative cardiac catheterization is often necessary to diagnose and treat residual anatomic defects. Experience with interventional catheterization to address post-operative concerns is limited. This was a retrospective cohort study. The medical and catheterization data of pediatric patients who underwent a cardiac catheterization ≤30 days after congenital heart surgery between November 2004 and July 2013 were reviewed. Patients who underwent right heart catheterization and endomyocardial biopsy after heart transplantation were excluded. A total of 219 catheterizations (91 interventional procedures, 128 noninterventional catheterizations) were performed on 193 patients. Sixty-five interventions (71.43%) were dilations, either balloon angioplasty or stent implantation. There was no difference in survival to hospital discharge between those who underwent an interventional versus noninterventional catheterization (p = 0.93). One-year post-operative survival was comparable between those who underwent an intervention (66%) versus diagnostic (71%) catheterization (p = 0.58). There was no difference in the incidence of major or minor complications between the interventional and diagnostic catheterization cohorts (p = 0.21). Cardiac catheterization, including transcatheter interventions, can be performed safely in the immediate post-operative period after congenital heart surgery.

  14. Paediatric dissecting posterior cerebral aneurysms: report of two cases and review of the literature

    Vilela, Pedro; Goulao, Augusto [Garcia de Orta Hospital, Neuroradiology Department, Almada (Portugal)


    Intracranial aneurysms in the paediatric population are uncommon, accounting for 2% to 6% of all aneurysms, and spontaneous arterial dissection is rarely reported as the cause of aneurysms in children, especially in the posterior cerebral artery. Two cases of paediatric spontaneous posterior cerebral artery dissecting aneurysms are reported, one in a 33-month-old male child presenting with aneurysmal rupture and subarachnoid haemorrhage and the other in a 9-year-old boy with an unruptured aneurysm. The first child was successfully treated by endovascular parent vessel occlusion without neurological deficit and in the second a spontaneous thrombosis of the aneurysm and its parent artery occurred associated with hydrocephalus and a favourable outcome. Dissecting aneurysms are dynamic lesions with variable and unpredictable evolution and close follow-up and/or early treatment is warranted. Spontaneous arterial dissection is a rare, probably still under-recognized, cause of intracranial aneurysms that may be responsible for a significant number of aneurysms and spontaneous aneurysmal thromboses in children.

  15. Surgical correction of ruptured aneurysms of the sinus of Valsalva using on-pump beating-heart technique

    Lin Hui


    Full Text Available Abstract Background Rupture of aneurysms of the sinus of Valsalva results in abrupt onset of congestive heart failure. On-pump beating-heart surgery may reduce cardiac impairment by maintaining coronary blood flow and avoiding cardioplegia. Herein, we report the operative correction of thirty-one patients of ruptured aneurysms of the sinus of Valsalva, using the on-pump beating-heart technique. Methods Thirty-one patients with ruptured aneurysms of the sinus of Valsalva underwent operative corrections using the on-pump beating-heart technique. In patients with fistula diameter less than 1 cm and no aortic regurgitation, the aorta was unclamped throughout cardiopulmonary bypass(CPB while receiving antegrade heart perfusion. In remainder of patients, retrograde perfusion was used. Results After intracardiac manipulation was complete and the nasopharyngeal temperature was raised to 36-37°C, the patients were smoothly weaned off CPB. There were no early or late postoperative deaths. All patients were in New York Heart Association functional class I at follow-up (range, 0.5-1 year. Mild-to-moderate aortic valve regurgitation was observed in one patient. No recurrence of the left-to-right shunt from ruptured aneurysms of the sinus of Valsalva was observed. Conclusions Beating heart on pump allows adequate examination of the aortic lesion under near-physiologic conditions, allows decrease in ischemia-reperfusion injury and potentially decreases the risk of serious or fatal rhythm disturbances. On-pump beating-heart technique for repair of ruptured aneurysm of sinus of Valsalva is feasible and promising. Antegrade heart perfusion is suitable for patients with a fistula diameter

    Filis, Konstantinos; Martinakis, Vasilios; Galyfos, George; Sigala, Fragiska; Theodorou, Dimitris; Andreadou, Ioanna; Zografos, Georgios


    Aim. Although osteopontin (OPN) and osteoprotegerin (OPG) have been associated with abdominal aortic aneurysms (AAAs), no association of these two biomarkers with AAA surgical or endovascular treatment has been reported. Material and Methods. Seventy-four AAA patients were prospectively selected for open or endovascular repair. All aneurysms were classified (Types A-E) according to aneurysmal extent in CT imaging (EUROSTAR criteria). All patients had preoperative serum OPN and OPG values measurements and 1 week after the procedure. Preoperative and postoperative values were compared with a control group of twenty patients (inguinal hernia repair). Results. Preoperative OPN values in patients with any type of aneurysm were higher than in the control group, while OPG values showed no difference. Postoperative OPN values in AAA patients were higher than in the control group. OPN values increased after open surgery and after EVAR. OPG values increased after open surgery but not after EVAR. There was no difference in OPN/OPG values between EVAR and open surgery postoperatively. Conclusions. OPN values are associated with aneurysm presence but not with aneurysm extent. OPG values are not associated either with aneurysm presence or with aneurysm extent. OPN values increase after AAA repair, independently of the type of repair.

    Objective To compare the advantages and disadvantages of continuous lumbar cerebrospinal fluid drainage and repeated lumbar puncture for ruptured intracranial aneurysm surgery.Methods 295 patients were enrolled who had ruptured intracranial aneurysm and were treated surgically between Jan 2010 and Jan 2011 in department of neurosurgery.Patients were classified into 2 groups:patients who were performed with continuous lumbar cerebrospinal fluid drainage (group A) and patients who were performed with repeated lumbar puncture (group B).The incidence rates of major surgical complications of both groups were compared and analyzed,including delayed cerebral ischemia,postsurgical hydrocephalus and postsurgical intracranial infection.All patients were followed-up for over 6 months and the surgical outcomes were assessed using modified Rankin scale (mRS).Results The incidence rates of delayed cerebral ischemia were 4.38% (7/160) and 7.41% (10/135) in group A and B respectively.There was no significant difference between 2 groups.The incidence rates of postsurgical hydrocephalus were 2.50% (4/160) and 3.70% (5/135) in group A and B respectively.There was no significant difference between 2 groups.The incidence rates of intracranial infection were 8.13% (13/160) and 2.22% (3/135) in group A and B respectively.There was a higher rate of intracranial infection in group A (P < 0.05).There was no significant difference in mRS between 2 groups after 6-months follow-up.Conclusions Continuous lumbar cerebrospinal fluid drainage showed little advantage over repeated lumbar puncture in reducing the occurrence of major surgical complications,including delayed cerebral ischemia and postsurgical hydrocephalus.While continuous lumbar cerebrospinal fluid drainage had a higher incidence rate of intracranial infection.Continuous Lumbar cerebrospinal fluid drainage might enhance the risk of intracranial infection.The therapeutic indications of continuous lumbar cerebrospinal

  18. Takotsubo Cardiomyopathy Following Cardiac Surgery.

    Chiariello, Giovanni Alfonso; Bruno, Piergiorgio; Colizzi, Christian; Crea, Filippo; Massetti, Massimo


    Takotsubo cardiomyopathy syndrome, commonly occurring in postmenopausal women, is characterized by transient apical systolic dysfunction in absence of coronary lesions. The cardiomyopathy is often observed after intense stressful events such as a major surgical procedure. A 72-year-old woman symptomatic for dyspnea at rest, chest pain, and peripheral edema successfully underwent surgery for noncoronary sinus aneurysm-right atrium fistula repair. Two days after surgery the patient developed takotsubo syndrome, diagnosed according to the Mayo Clinic criteria. We reviewed the literature on takotsubo cardiomyopathy as a complication of major cardiac surgery procedures. Takotsubo cardiomyopathy is confirmed as a possible early complication of cardiac surgery. Exaggerated sympathetic stimulation may cause massive endogenous catecholamine release. Hypoperfusion during cardiopulmonary bypass, inotropic drugs administration, and postoperative anxiety and pain are all factors generating stress, possible coronary artery spasm and transient cardiomyopathy, clinically simulating acute myocardial infarction. Several clinical features have been described such as acute mitral insufficiency, systolic anterior motion of the anterior mitral valve leaflet, left ventricular outflow tract obstruction, acute cardiac failure, and cardiogenic shock. Intraventricular thrombi and adverse cerebrovascular events may also be possible complications. Rare catastrophic events such as left ventricular free wall rupture and ventricular septal perforation have been also encountered. After cardiac surgery takotsubo cardiomyopathy should be suspected if clinical and instrumental criteria are met, and promptly differentiated from the more frequent acute myocardial infarction. Prognosis may be favorable if appropriate conservative medical treatment is promptly started. © 2015 Wiley Periodicals, Inc.

  19. Endovascular Management of True Renal Arterial Aneurysms: Results from a Single Centre

    Chung, Raymond, E-mail: [Khoo Teck Puat Hospital, Department of Radiology (Singapore); Touska, Philip, E-mail: [St. George’s Hospital NHS Trust, Department of Radiology (United Kingdom); Morgan, Robert; Belli, Anna-Maria [St. George’s Hospital NHS Trust, Department of Interventional Radiology (United Kingdom)


    PurposeTo report a single centre’s experience of the endovascular treatment of renal arterial aneurysms, including techniques and outcomes.Materials and MethodsThis is a retrospective analysis of true renal arterial aneurysms (TRAAs) treated using endovascular techniques over a period of 12 years and 10 months. The clinical presentations, aneurysm characteristics, endovascular techniques and outcomes are reported.ResultsThere were nine TRAA cases with a mean aneurysm size of 21.0 mm, located at the main renal arterial bifurcation in all cases. Onyx{sup ®} was used as the embolic agent of choice (88.9 % cases), with concurrent balloon remodelling. The overall primary technical success rate was 100 %. Repeat intervention was carried out in 1 case, secondary to reperfusion >8 years post-initial treatment. Long-term clinical follow-up was available in 55.6 % of cases (mean 29.8 months; range 3.3–90.1 months). Early post-procedural renal function, as measured by serum creatinine, remained within the normal reference range. Renal parenchymal loss post-embolisation was ≤20 % in 77.8 % of cases, as estimated on imaging. Minor complications included non-target embolization of Onyx{sup ®} with no clinical sequelae (n = 1), transient pain requiring only oral analgesia with no prolongation of hospital stay (n = 2). No major complications occurred as a consequence of embolisation.ConclusionEndovascular therapy is an effective and safe primary therapy for TRAA with high success rate and low morbidity, supplanting surgery as primary therapy. Current experience in the use of Onyx{sup ®} in TRAA is primarily limited to individual case reports, and this represents the largest case series of Onyx{sup ®}-treated TRAAs to date.

  20. Prognosis of patients in coma after acute subdural hematoma due to ruptured intracranial aneurysm.

    Torné, Ramon; Rodríguez-Hernández, Ana; Romero-Chala, Fabián; Arikan, Fuat; Vilalta, Jordi; Sahuquillo, Juan


    Acute subdural hematomas (aSDH) secondary to intracranial aneurysm rupture are rare. Most patients present with coma and their functional prognosis has been classically considered to be very poor. Previous studies mixed good-grade and poor-grade patients and reported variable outcomes. We reviewed our experience by focusing on patients in coma only and hypothesized that aSDH might worsen initial mortality but not long-term functional outcome. Between 2005 and 2013, 440 subarachnoid hemorrhage (SAH) patients were admitted to our center. Nineteen (4.3%) were found to have an associated aSDH and 13 (2.9%) of these presented with coma. Their prospectively collected clinical and outcome data were reviewed and compared with that of 104 SAH patients without aSDH who presented with coma during the same period. Median aSDH thickness was 10mm. Four patients presented with an associated aneurysmal cortical laceration and only one had good recovery. Overall, we observed good long-term outcomes in both SAH patients in coma with aSDH and those without aSDH (38.5% versus 26.4%). Associated aSDH does not appear to indicate a poorer long-term functional prognosis in SAH patients presenting with coma. Anisocoria and brain herniation are observed in patients with aSDH thicknesses that are smaller than those observed in trauma patients. Despite a high initial mortality, early surgery to remove the aSDH results in a good outcome in over 60% of survivors. Aneurysmal cortical laceration appears to be an independent entity which shows a poorer prognosis than other types of aneurysmal aSDH.

  1. [Incidence and causes of early end in awake surgery for language mapping not directly related to eloquence].

    Villalba, Gloria; Pacreu, Susana; Fernández-Candil, Juan Luis; León, Alba; Serrano, Laura; Conesa, Gerardo


    The incidence and causes that may lead to an early end (unfinished cortical/subcortical mapping) of awake surgery for language mapping are little known. A study was conducted on 41 patients with brain glioma located in the language area that had awake surgery under conscious sedation. Surgery was ended early in 6 patients. The causes were: tonic-clonic seizure (1), lack of cooperation due to fatigue/sleep (4), whether or not word articulation was involved, a decreased level of consciousness for ammonia encephalopathy that required endotracheal intubation (1). There are causes that could be expected and in some cases avoided. Tumour size, preoperative aphasia, valproate treatment, and type of anaesthesia used are variables to consider to avoid failure in awake surgery for language mapping. With these results, the following measures are proposed: l) If the tumour is large, perform surgery in two times to avoid fatigue, 2) if patient has a preoperative aphasia, do not use sedation during surgery to ensure that sleepiness does not cause worse word articulation, 3) if the patient is on valproate treatment, it is necessary to rule out the pre-operative symptoms that are not due to ammonia encephalopathy.

  2. Reliable? The Value of Early Postoperative Magnetic Resonance Imaging after Cerebral Cavernous Malformation Surgery.

    Chen, Bixia; Göricke, Sophia; Wrede, Karsten; Jabbarli, Ramazan; Wälchli, Thomas; Jägersberg, Max; Sure, Ulrich; Dammann, Philipp


    Cerebral cavernous malformations (CCM) can cause intracerebral hemorrhage. The lesions themselves are frequently associated with perifocal hemosiderin deposits caused by repetitive microhemorrhages. Main indications for a surgical treatment are recurrent symptomatic hemorrhages or cavernoma-related epilepsy. After surgical resection, follow-up magnetic resonance imaging (MRI) is usually performed to confirm 1) the complete resection of the CCM and, especially in cases of cavernoma-related epilepsy, 2) the complete resection of the hemosiderin deposits. This prospective study evaluates the value of early postoperative MRI (within 72 hours) regarding the detection of CCM or hemosiderin remnants compared with a standard 3-6 months postoperative MRI control in 61 CCM cases. Sensitivity of early postoperative MRI for CCM remnant detection was 66.67% (95% confidence interval [CI], 9.43%-99.16%), specificity was 76.74% (95% CI, 61.37%-88.24%), positive predictive value was 16.67% (95% CI, 2.09%-48.41%), and negative predictive value was 97.06% (95% CI, 84.67%-99.93%). Because of the high number of patients who could not be evaluated because of imaging artifacts, sensitivity and specificity analysis was not performed for early postoperative MRI using T2*/susceptibility-weighted imaging to assess hemosiderin remnants. Sensitivity of early postoperative MRI for hemosiderin remnant detection using T2-weighted sequences was 85.71% (95% CI, 63.66%-96.95%), specificity was 66.67% (95% CI, 44.68%-84.37%), positive predictive value was 69.23% (95% CI, 55.45%-80.27%), and negative predictive value was 84.21% (95% CI, 64.31%-94.04%). Our data suggest that early postoperative MRI after CCM surgery is often hampered by imaging artifacts creating false-positive results and therefore ineligible for a resection control. However, reliability of a negative result on early postoperative T2-weighted MRI is relatively high regarding both CCM and hemosiderin remnants. Copyright © 2017

    Objective To retrospectively analyze and compare conservative versus surgical treatment of patients with fulminant acute pancreatitis (FAP) plus abdominal compartment syndrome (ACS). Methods From January 1998 to September 2005, 21 patients with FAP plus ACS were retrospectively analyzed. Ten patients were conservatively treated by means of intensive care medicine without surgery, and 11 patients received open surgical management and suction drainage. Results Seven of the 10 non-surgical patients died, comprising one with mild, four with moderate and two with severe ACS (70% mortality rate). Of the 11 patients receiving open surgical management in the early phase (within 3 days of disease initiation), three died, comprising one with moderate and two with severe ACS (27.3% mortality rate). The difference in mortality rates was found to be statistically significant. Conclusion Our data indicate patients suffering FAP with severe ACS should be treated with open management of the abdomen in the early phase (within 3 days), even in the absence of infection. This approach appears superior to that of conservative management. Surgical treatment resulted in abdominal decompression and subsequently significantly decreased the mortality rate and improved overall prognosis.

  5. Early MT-1 MMP expression following elastase exposure is associated with increased cleaved MMP-2 activity in experimental rodent aortic aneurysms.

    Sinha, Indranil; Hannawa, Kevin K; Eliason, Jonathan L; Ailawadi, Gorav; Deogracias, Michael P; Bethi, Siddharth; Ford, John W; Roelofs, Karen J; Grigoryants, Vladimir; Henke, Peter K; Stanley, James C; Upchurch, Gilbert R


    The objective of this study was to determine the significance of membrane type 1 matrix metalloproteinase (MT1-MMP) activation of MMP-2 in experimental abdominal aortic aneurysms. Rat aortas were perfused with either saline as a control or elastase, and harvested on 2, 4, or 7 days after perfusion (n = 5 per treatment group/day). Aortic MT1-MMP and MMP-2 expression and protein were determined by real time polymerase chain reaction and Western blotting, respectively. Aortic explants were used to measure MMP-2 activity by zymography. Rat aortic smooth muscle cells in vitro were exposed to increasing doses of elastase and analyzed for MT-1 MMP expression. Aneurysms formed in 80% of the elastase-perfused aortas at 7 days, whereas none formed in the saline-perfused aortas. Significantly increased MT1-MMP expression was observed only on day 4, when levels were 6.5-fold higher in elastase-perfused aortas compared with saline-perfused aortas (P < .01). By day 7, MT1-MMP protein was present only in the elastase-perfused aortas (P = .02). By immunohistochemistry, MT1-MMP was detectable only in the elastase-perfused group at day 7. Cleaved MMP-2 activity (P = .045) was increased in elastase-perfused aortas compared with saline perfused aortas at day 7. In rat aortic smooth muscle cells, MT-1 MMP expression increased in response to elastase (P = .02). The rodent aortic aneurysm model exhibits upregulation of MT1-MMP expression and protein with subsequent increased conversion of MMP-2 from the latent to the cleaved form.

    Full Text Available Abstract Background Visceral artery aneurysms although rare, have very high mortality if they rupture. Case presentation An interesting case of a bleeding inferior pancreaticduodenal artery aneurysm is reported in a young patient who presented with hypovolemic shock while being treated in the hospital after undergoing total knee replacement. Endovascular embolization was successfully employed to treat this patient, with early hospital discharge. Conclusion Prompt diagnosis and endovascular management of ruptured visceral aneuryms can decrease the associated mortality and morbidity.

    Background:The development of three-dimensional (3D) printing technology provides a new method for surgical treatment,but currently there are few reports on its application in the treatment of aneurysm.The aim of the present study was to explore the materials and methods of fabricating 3D printed individual aneurysm model and its value in the treatment of intracranial aneurysm.Methods:Twenty-four patients with intracranial aneurysm diagnosed by CTA who had undergone operation in our hospital were analyzed retrospectively.CTA Data collected at the time of surgery was used for reconstruction.Soft Mimics 17.0 was used to reconstruct the thin layer CTA scan data into 3D image and the final data was sent to the 3D printer for fabricating the model.We compared the proposed 3D printed model-based preoperative plan and the actual approach used in the surgery based on CTA data to evaluate the value of the 3D printed model in preoperative planning,and picked out the materials which were more suitable for the clinic.Results:Twenty-four aneurysm models with high degree of reality were fabricated successfully with 3D-printing technology.The patients' blood vessels,skulls and aneurysms were printed into the reality model at a ratio of 1:1.It is reported that the soft material-based,3D printed vascular and aneurysm model more closely resembled the characteristics of the real blood vessels,thus provides a better simulation compared to the plaster-based model.Compared with the original operation plan,3D printed model could be used for pre-operative aneurysm clip selection,and provide more intuitive information in selection of operational approach.Conclusions:3D printed model can be used as an operational physical model to design operative schemes,choose the best operative paths and select suitable aneurysm clips by its high simulation degree and individualized characteristics.The model is helpful for surgical planning,especially for the preoperative plan of treating refractory

  11. Early Post Operative Enteral Versus Parenteral Feeding after Esophageal Cancer Surgery

    Mohammadtaghi Rajabi Mashhadi


    Full Text Available Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients.   Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein          (hs-CRP, as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group.   Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction.   Conclusion:  The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

  12. Bypass surgery for unresectable oesophageal cancer: early and late results in 124 cases.

    Mannell, A; Becker, P J; Nissenbaum, M


    The early and late results of bypass surgery in 124 patients with unresectable oesophageal cancer are reported. Patients were grouped according to the extent of disease: group A, tumour localized to the oesophagus where severe pulmonary disease contra-indicated oesophagectomy (n = 9); group B, tumour less than or equal to 10 cm in length with mediastinal invasion (n = 81); group C, tumour greater than 10 cm in length with mediastinal invasion and/or fixed malignant lymph nodes (n = 33). Extent of disease was not recorded in one patient. The operative mortality was 4 per cent but 9 other patients died in hospital (hospital mortality, 11 per cent). Mortality was increased in patients undergoing colon bypass and in those with a large tumour load but these differences failed to reach statistical significance. The most frequent complication was neck sepsis, secondary to leakage from the proximal end of the excluded oesophagus. Eighty-nine per cent of the survivors could eat a normal, unrestricted diet on discharge and eighty-two per cent of survivors had complete and lasting relief from dysphagia. Median survival after bypass was 5 months but survival was significantly improved by radiotherapy to the tumour (P less than 0.001). Gastric bypass with radiotherapy is indicated in patients with extra-oesophageal spread of malignancy and in patients with tumours localized to the oesophagus who are unfit for resection. Bypass surgery may be contra-indicated in patients with a primary tumour greater than 10 cm in length and/or fixed lymph node metastases because mortality is increased and survival after operation is short.

  13. A review article on the benefits of early mobilization following spinal surgery and other medical/surgical procedures

    Nancy E Epstein


    Full Text Available Background: The impact of early mobilization on perioperative comorbidities and length of stay (LOS has shown benefits in other medical/surgical subspecialties. However, few spinal series have specifically focused on the "pros" of early mobilization for spinal surgery, other than in acute spinal cord injury. Here we reviewed how early mobilization and other adjunctive measures reduced morbidity and LOS in both medical and/or surgical series, and focused on how their treatment strategies could be applied to spinal patients. Methods: We reviewed studies citing protocols for early mobilization of hospitalized patients (day of surgery, first postoperative day/other in various subspecialties, and correlated these with patients′ perioperative morbidity and LOS. As anticipated, multiple comorbid factors (e.g. hypertension, high cholesterol, diabetes, hypothyroidism, obesity/elevated body mass index hypothyroidism, osteoporosis, chronic obstructive pulmonary disease, coronary artery disease and other factors contribute to the risks and complications of immobilization for any medical/surgical patient, including those undergoing spinal procedures. Some studies additionally offered useful suggestions specific for spinal patients, including prehabilitation (e.g. rehabilitation that starts prior to surgery, preoperative and postoperative high protein supplements/drinks, better preoperative pain control, and early tracheostomy, while others cited more generalized recommendations. Results: In many studies, early mobilization protocols reduced the rate of complications/morbidity (e.g. respiratory decompensation/pneumonias, deep venous thrombosis/pulmonary embolism, urinary tract infections, sepsis or infection, along with the average LOS. Conclusions: A review of multiple medical/surgical protocols promoting early mobilization of hospitalized patients including those undergoing spinal surgery reduced morbidity and LOS.

  19. Endovascular treatment of very small intracranial aneurysms

    Iskandar, A; Nepper-Rasmussen, J


    The endovascular treatment of intracranial aneurysms 3 mm or less is considered controversial. The purpose of this study is to report angiographic and clinical results following coiling of such aneurysms and compare them to those of larger aneurysms (> 3 mm).Between November 1999 and November 2009...... endovascular treatment was attempted in 956 consecutive intracranial aneurysms. Of 956 aneurysms, 111 aneurysms were very small aneurysms with a maximal diameter of 3 mm or less. We conducted a retrospective analysis of angiographic and clinical outcome following coiling of very small aneurysms...... and subsequently comparing it to the results of larger aneurysms.Coiling initially failed in eight aneurysms. In the remaining 103 aneurysms endovascular treatment was accomplished and immediate angiographic results showed complete aneurysm occlusion in 43 aneurysms, nearly complete aneurysm occlusion in 54...

    Full Text Available Objective From our personal experiences, it is our wish to examine the incidence of ruptured intracranial aneurysms about four decades ago in Jamaica, the West Indies, with regards to postoperative deterioration of neurological/psychological functions. Materials and Method The author, while working in Jamaica, the West Indies, from 1975 to 1977 (3 years, operated on 6 cases of ruptured intracranial aneurysms of 5 females and 1 male. The source of these data is from the author′s surgery records. Result There were 4 aneurysms from the posterior communicating artery, and 1 each from the anterior communicating artery, and the middle cerebral artery. Their ages ranged from 31 to 64 years. They presented with diverse neurological disturbances. Their aneurysms, which were diagnosed through contrast carotid angiography, were all clipped through fronto-lateral craniotomy under general anaesthesia. The procedures were well tolerated by the patients. There were no complications and no gross additional neurological deficits postoperatively. The wounds had healed by primary intention. The patients were discharged home 12 days postoperatively, the stitches having been removed 2 days earlier. Follow-up checks started about 7 days after discharge. The neurological deficits had cleared about 3 months later. Conclusion Having bled, the aneurysms exposed themselves by causing sudden severe headaches, and various neurological problems, depending on their locations. We found more females than males. The posterior communicating artery aneurysm was predominant. There were no cerebro-vascular spasms postoperatively. Greek ANEURYSMA (Ana= up or across, eurys - wide or broad

    Objective To compare the clinical value of digital subtraction angiography (DSA) and magnetic resonance angiography (MRA) in grading intracranial aneurysm postoperation. Methods The study recruitcd 72 patients after surgery for intracranial aneurysm. The grading of intracranial aneurysm postoperation and follow-up for three months was performed by DSA and MRA. Results Grading by DSA and TOF-MRA of intracranial aneurysm after follow-up for three months did not differ significantly ( χ2 =0. 95, P>0.05). The sensitivity of Class I intracranial aneurysm postoperation detected by MRA and DSA was 94. 3% and 97. 1% while the specificity was 91.9% and 89.2%, respectively, without significant difference (P>0.05). The grading of intracranial aneurysm postoperation and follow-up increased with the incidence of high blood pressure ( χ2=7.82, P0.05). Conclusion MRA and DSA can be used in follow-up of intracranial aneurysm surgery. The former is a non-invasive means of examination, thus deserving wide clinical application.%目的 探讨磁共振血管造影(MRA)和数字减影血管造影(DSA)两种技术对颅内动脉瘤术后分级的临床价值.方法 对72例颅内动脉瘤术后患者使用DSA和MRA技术检测颅内动脉瘤术后及随访3个月的分级情况,并对比检查结果.结果 DSA与TOF MRA对颅内动脉瘤随访3个月分级的比较差异无统计学意义(x2=0.95,P>0.05);MRA和DSA检测术后颅内动脉瘤1级的灵敏度分别为94.3%、97.1%,特异度分别为91.900、89.2%,两种方法检测差异无统计学意义(P>0.05);术后随访颅内动脉瘤分级的增加随高血压的发生率而增加(x2= 7.82,P<0.05),与高血压成正相关(r=0.47,P<0.05);MRA和DSA检测术后颅内动脉瘤患者脑血管平均分支数差异无统计学意义(P>0.05).结论 MRA与DSA均可应用于随访术后颅内动脉瘤残留瘤的分级,MRA还有无创性检查的优势,值得临床推广.

  4. Mouse models of intracranial aneurysm.

    Wang, Yutang; Emeto, Theophilus I; Lee, James; Marshman, Laurence; Moran, Corey; Seto, Sai-wang; Golledge, Jonathan


    Subarachnoid hemorrhage secondary to rupture of an intracranial aneurysm is a highly lethal medical condition. Current management strategies for unruptured intracranial aneurysms involve radiological surveillance and neurosurgical or endovascular interventions. There is no pharmacological treatment available to decrease the risk of aneurysm rupture and subsequent subarachnoid hemorrhage. There is growing interest in the pathogenesis of intracranial aneurysm focused on the development of drug therapies to decrease the incidence of aneurysm rupture. The study of rodent models of intracranial aneurysms has the potential to improve our understanding of intracranial aneurysm development and progression. This review summarizes current mouse models of intact and ruptured intracranial aneurysms and discusses the relevance of these models to human intracranial aneurysms. The article also reviews the importance of these models in investigating the molecular mechanisms involved in the disease. Finally, potential pharmaceutical targets for intracranial aneurysm suggested by previous studies are discussed. Examples of potential drug targets include matrix metalloproteinases, stromal cell-derived factor-1, tumor necrosis factor-α, the renin-angiotensin system and the β-estrogen receptor. An agreed clear, precise and reproducible definition of what constitutes an aneurysm in the models would assist in their use to better understand the pathology of intracranial aneurysm and applying findings to patients.

    This study was performed to evaluate the disease-free survival and risk factors of recurrence in early breast cancer patients who have undergone breast conserving surgery and radiation therapy. Materials and Methods: From March 1997 to December 2002, 77 breast cancer patients who underwent breast conserving surgery and radiation therapy were reviewed retrospectively. The median follow-up time was 58.4 months (range 43.8-129.4 months) and the mean subject age was 41 years. The frequency distribution of the different T stages, based on the tumor characteristics was 38 (49.3%) for T1, 28 (36.3%) for T2, 3 for T3, 7 for Tis and 1 for an unidentified sized tumor. In addition, 52 patients (67.5%) did not have axillary lymph metastasis, whereas 14 patients (18.1%) had 1-3 lymph node metastases and 3 (0.03%) had more than 4 lymph node metastases. The resection margin was negative in 59 patients, close ({<=}2 mm) in 15, and positive in 4. All patients received radiation therapy at the intact breast using tangential fields with a subsequent electron beam boost to the tumor bed at a total dose ranging from 59.4 Gy to 66.4 Gy. Patients with more than four positive axillary lymph nodes received radiation therapy (41.4-60.4 Gy) at the axillary and supraclavicular area. Chemotherapy was administered in 59 patients and tamoxifen or fareston was administered in 29 patients. Results: The 5 year overall survival and disease-free survival rates were 98.08% and 93.49%, respectively. Of the 77 patients, a total of 4 relapses (5.2%), including 1 isolated supraclavicular relapse, 1 supraclavicular relapse with synchronous multiple distant relapses, and 2 distant relapses were observed. No cases of local breast relapses were observed. Lymph node metastasis or number of metastatic lymph nodes was not found to be statistically related with a relapse (p=0.3289) nor disease-free survival (p=0.1430). Patients with positive margins had a significantly shorter disease-free survival period (p<0

  7. Early Surgery versus Initial Conservative Treatment in Patients with Traumatic Intracerebral Hemorrhage (STITCH[Trauma]): The First Randomized Trial.

    Mendelow, A David; Gregson, Barbara A; Rowan, Elise N; Francis, Richard; McColl, Elaine; McNamee, Paul; Chambers, Iain R; Unterberg, Andreas; Boyers, Dwayne; Mitchell, Patrick M


    Intraparenchymal hemorrhages occur in a proportion of severe traumatic brain injury TBI patients, but the role of surgery in their treatment is unclear. This international multi-center, patient-randomized, parallel-group trial compared early surgery (hematoma evacuation within 12 h of randomization) with initial conservative treatment (subsequent evacuation allowed if deemed necessary). Patients were randomized using an independent randomization service within 48 h of TBI. Patients were eligible if they had no more than two intraparenchymal hemorrhages of 10 mL or more and did not have an extradural or subdural hematoma that required surgery. The primary outcome measure was the traditional dichotomous split of the Glasgow Outcome Scale obtained by postal questionnaires sent directly to patients at 6 months. The trial was halted early by the UK funding agency (NIHR HTA) for failure to recruit sufficient patients from the UK (trial registration: ISRCTN19321911). A total of 170 patients were randomized from 31 of 59 registered centers worldwide. Of 82 patients randomized to early surgery with complete follow-up, 30 (37%) had an unfavorable outcome. Of 85 patients randomized to initial conservative treatment with complete follow-up, 40 (47%) had an unfavorable outcome (odds ratio, 0.65; 95% confidence interval, CI 0.35, 1.21; p=0.17), with an absolute benefit of 10.5% (CI, -4.4-25.3%). There were significantly more deaths in the first 6 months in the initial conservative treatment group (33% vs. 15%; p=0.006). The 10.5% absolute benefit with early surgery was consistent with the initial power calculation. However, with the low sample size resulting from the premature termination, we cannot exclude the possibility that this could be a chance finding. A further trial is required urgently to assess whether this encouraging signal can be confirmed.

  8. Anatomic Total Talar Prosthesis Replacement Surgery and Ankle Arthroplasty: An Early Case Series in Thailand


    Little is known about specific outcomes and early experiences of total talar prosthesis replacement surgery in the current literature, and ankle arthroplasty in Southeast Asia. This study reported on four patients with talar loss or ankle arthritis. Patients were treated with a custom total talar prosthesis (anatomic-metallic version) replacement (TPR, n=1) or with total ankle replacement (TAR, n=3). Baseline data, including Visual-Analog-Scale Foot and Ankle (VAS-FA) and Quality of Life scores via Short-Form-36 (SF-36), were collected for all patients. Mean follow-up time was 7.6 months. From preoperative to postoperative, VAS-FA score increased from 6.0 to 57.5, and SF-36 score increased from 19.3 to 73.7 in a patient with TPR. Mean VAS-FA scores increased from 51.5±15.6 to 85.7±4.7 (P=0.032), and mean SF-36 scores tended to increase from 65.2±13.3 to 99.3±1.2 (P=0.055) in TAR group. This study is the first report of anatomic-metallic TPR which appears to provide satisfactory outcomes for treatment of talar loss at a short-term follow-up. TAR also provides acceptable results for treatment of ankle arthritis at this point. PMID:25317313

  9. Predicting Delirium Duration in Elderly Hip-Surgery Patients: Does Early Symptom Profile Matter?

    Chantal J. Slor


    Full Text Available Background. Features that may allow early identification of patients at risk of prolonged delirium, and therefore of poorer outcomes, are not well understood. The aim of this study was to determine if preoperative delirium risk factors and delirium symptoms (at onset and clinical symptomatology during the course of delirium are associated with delirium duration. Methods. This study was conducted in prospectively identified cases of incident delirium. We compared patients experiencing delirium of short duration (1 or 2 days with patients who had more prolonged delirium (≥3 days with regard to DRS-R-98 (Delirium Rating Scale Revised-98 symptoms on the first delirious day. Delirium symptom profile was evaluated daily during the delirium course. Results. In a homogenous population of 51 elderly hip-surgery patients, we found that the severity of individual delirium symptoms on the first day of delirium was not associated with duration of delirium. Preexisting cognitive decline was associated with prolonged delirium. Longitudinal analysis using the generalised estimating equations method (GEE identified that more severe impairment of long-term memory across the whole delirium episode was associated with longer duration of delirium. Conclusion. Preexisting cognitive decline rather than severity of individual delirium symptoms at onset is strongly associated with delirium duration.

  11. Activation of Endocannabinoid System Is Associated with Persistent Inflammation in Human Aortic Aneurysm

    Christopher Gestrich


    Full Text Available Human aortic aneurysms have been associated with inflammation and vascular remodeling. Since the endocannabinoid system modulates inflammation and tissue remodeling, we investigated its components in human aortic aneurysms. We obtained anterior aortic wall samples from patients undergoing elective surgery for aortic aneurysm or coronary artery disease as controls. Histological and molecular analysis (RT-qPCR was performed, and endocannabinoid concentration was determined using LC-MRM. Patient characteristics were comparable between the groups except for a higher incidence of arterial hypertension and diabetes in the control group. mRNA level of cannabinoid receptors was significantly higher in aneurysms than in controls. Concentration of the endocannabinoid 2-arachidonoylglycerol was significantly higher, while the second endocannabinoid anandamide and its metabolite arachidonic acid and palmitoylethanolamide were significantly lower in aneurysms. Histology revealed persistent infiltration of newly recruited leukocytes and significantly higher mononuclear cell density in adventitia of the aneurysms. Proinflammatory environment in aneurysms was shown by significant upregulation of M-CSF and PPARγ but associated with downregulation of chemokines. We found comparable collagen-stained area between the groups, significantly decreased mRNA level of CTGF, osteopontin-1, and MMP-2, and increased TIMP-4 expression in aneurysms. Our data provides evidence for endocannabinoid system activation in human aortic aneurysms, associated with persistent low-level inflammation and vascular remodeling.

  12. Case of radiation induced aneurysm of extracranial carotid artery

    Tashiro, Takashi; Ikota, Toshio; Yamashita, Kousuke; Kodama, Takao


    An unusual case of post-irradiation aneurysm of extracranial internal carotid artery is presented. A 70-year-old man, complaining of left cervical throbbing mass with focal pain, was admitted on February 8, 1985. It was noted, from his past history, that he had had surgery of the removal of cervical lymphnodes and that unknown dosage of irradiation had been added to the cervical region 30 years before. Left carotid angiography (on admission) demonstrated a giant aneurysm in the cervical portion of internal carotid artery. Right carotid angiography with compression of left carotid artery revealed good cross filling through anterior communicating artery. Computed tomography with contrast media showed a ring like enhanced mass, which was thought to suggest that a large part of the aneurysm was filled with intraluminal thrombosis. During 30 days of evaluation, the aneurysm grew larger and his cervical pain became untolerable. Operation, the resection of the aneurysm and the reconstruction (of circulation) with vein graft, was challenged on March 12. It was so difficult with meticulous work that the ligation of left common carotid artery was performed after all. Seven days after the operation, he suffered from the gastrointestinal bleeding, which was enough to lead him to hypovolemic shock. Thereafter, right hemiparesis and aphasia were brought about. Two months later, he died of pneumonia. On histological examination, it was demonstrated that the aneurysm communicated with the necrotic tissue and that the normal structure of the blood vessel was not observed in the aneurysmal wall and consisted of the collagenous fiber and granulated tissue. The aneurysm was interpreted as a false one.

  13. Pulsatile blood flow in Abdominal Aortic Aneurysms

    Salsac, Anne-Virginie; Lasheras, Juan C.; Singel, Soeren; Varga, Chris


    We discuss the results of combined in-vitro laboratory measurements and clinical observations aimed at determining the effect that the unsteady wall shear stresses and the pressure may have on the growth and eventual rupturing of an Abdominal Aortic Aneurysm (AAA), a permanent bulging-like dilatation occurring near the aortic bifurcation. In recent years, new non-invasive techniques, such as stenting, have been used to treat these AAAs. However, the development of these implants, aimed at stopping the growth of the aneurysm, has been hampered by the lack of understanding of the effect that the hemodynamic forces have on the growth mechanism. Since current in-vivo measuring techniques lack the precision and the necessary resolution, we have performed measurements of the pressure and shear stresses in laboratory models. The models of the AAA were obtained from high resolution three-dimensional CAT/SCANS performed in patients at early stages of the disease. Preliminary DPIV measurements show that the pulsatile blood flow discharging into the cavity of the aneurysm leads to large spikes of pressure and wall shear stresses near and around its distal end, indicating a possible correlation between the regions of high wall shear stresses and the observed location of the growth of the aneurysm.

A ruptured splenic artery aneurysm was discovered at the time of laparotomy and cesarean delivery. The patient made a full recovery following resection of the aneurysm. The neonate survived but suffered severe neurologic impairment. Conclusion. The diagnosis of ruptured splenic artery aneurysm should be considered in a pregnant woman presenting with signs of intra-abdominal hemorrhage. Early intervention by a multidisciplinary surgical team is key to preserving the life of the mother and fetus.

    Bornak, Arash; Baqai, Atif; Li, Xiaoyi; Rey, Jorge; Tashiro, Jun; Velazquez, Omaida C


    Enlarging aneurysms in the thoracic aorta frequently remain asymptomatic. Fistulization of thoracic aortic aneurysms (TAA) to adjacent structures or the presence of a patent ductus arteriosus and TAA may lead to irreversible cardiopulmonary sequelae. This article reports on a large aneurysm of the thoracic aorta with communication to the pulmonary artery causing pulmonary edema and cardiorespiratory failure. The communication was ultimately closed after thoracic endovascular aortic aneurysm repair allowing rapid symptom resolution. Early diagnosis and closure of such communication in the presence of TAA are critical for prevention of permanent cardiopulmonary damage.

  16. Main pulmonary artery aneurysm: a case report and review of the literature.

    Imazio, Massimo; Cecchi, Enrico; Giammaria, Massimo; Pomari, Franco; Tabasso, Maria Donata; Ghisio, Aldo; Forsennati, Pier Giuseppe; Beqaraj, Federico; Favro, Elisa; Trinchero, Rita; Brusca, Antonio


    Main pulmonary artery aneurysms are a rare entity with few available published data. As reported in the literature, operative treatment is commonly recommended but the relation between the size of the aneurysm, its localization, and the risk of rupture is not as well defined as for aortic aneurysms. Proximal lesions that involve the main branches of the pulmonary artery are usually apparent on chest radiographs and must be taken into consideration in the differential diagnosis of mediastinal masses. An early diagnosis allows timely surgical treatment. We report an unusual case of a main pulmonary artery aneurysm presenting with persistent non-productive cough and provide a review of the pertinent published data.

  17. Endovascular treatment of ruptured proximal pica aneurysms: A single-center 5-years experience

    Vivek Gupta


    Full Text Available Background and Purpose: Posterior inferior cerebellar artery (PICA like other intracranial arteries is prone to aneurysm formation. Aneurysms usually arise from the vertebral artery (VA - PICA junction and the proximal segment of the PICA. The use of endovascular treatment as an alternative treatment to surgery has been increasing. We present our last 5 years experience in treating the ruptured proximal PICA aneurysms. Materials and Methods: Retrospective analysis of records of all patients with ruptured VA-PICA junction aneurysms treated at our referral center between July 2008 and July 2013 was performed. Over the last 5 years, we came across 17 patients who had aneurysms of proximal PICA or VA-PICA junction out of which 13 patients underwent endovascular treatment for ruptured saccular VA-PICA junction aneurysms and were the focus of this research. Follow-up studies ranged from 6 months to 3 years. Results: All the patients presented with an acute intracranial hemorrhage on NCCT. All the aneurysms were at VA-PICA junction with partial or complete incorporation of PICA origin in the sac. Endovascular treatment of all the 13 aneurysm was successful in the first attempt. Aneurysms were treated with balloon assisted coiling either by placing the balloon across the VA-PICA junction (n = 3 or in the vertebral artery proper (n = 9. Stent assisted coiling VA-PICA was performed in one aneurysm (n = 1. There was no intra-procedural rupture of the aneurysms. Conclusion: Endovascular therapy of ruptured proximal PICA aneurysms is possible and safe with the use of adjuvant devices and should be considered as first line treatment.

  18. [Modern aortic surgery in Marfan syndrome--2011].

    Kallenbach, K; Schwill, S; Karck, M


    Marfan syndrome is a hereditary disease with a prevalence of 2-3 in 10,000 births, leading to a fibrillin connective tissue disorder with manifestations in the skeleton, eye, skin, dura mater and in particular the cardiovascular system. Since other syndromes demonstrate similar vascular manifestations, but therapy may differ significantly, diagnosis should be established using the revised Ghent nosology in combination with genotypic analysis in specialized Marfan centres. The formation of aortic root aneurysms with the subsequent risk of acute aortic dissection type A (AADA) or aortic rupture limits life expectancy in patients with Marfan syndrome. Therefore, prophylactic replacement of the aortic root needs to be performed before the catastrophic event of AADA can occur. The goal of surgery is the complete resection of pathological aortic tissue. This can be achieved with excellent results by using a (mechanically) valved conduit that replaces both the aortic valve and the aortic root (Bentall operation). However, the need for lifelong anticoagulation with Coumadin can be avoided using the aortic valve sparing reimplantation technique according to David. The long-term durability of the reconstructed valve is favourable, and further technical improvements may improve longevity. Although results of prospective randomised long-term studies comparing surgical techniques are lacking, the David operation has become the surgical method of choice for aortic root aneurysms, not only at the Heidelberg Marfan Centre. Replacement of the aneurysmal dilated aortic arch is performed under moderate hypothermic circulatory arrest combined with antegrade cerebral perfusion using a heart-lung machine, which we also use in thoracic or thoracoabdominal aneurysms. Close post-operative follow-up in a Marfan centre is pivotal for the early detection of pathological changes on the diseased aorta.

  19. Hybrid repair of penetrating aortic ulcer associated with right aortic arch and aberrant left innominate artery arising from aneurysmal Kommerell's diverticulum with simultaneous repair of bilateral common iliac artery aneurysms.

    Guo, Yuanyuan; Yang, Bin; Cai, Hongbo; Jin, Hui


    We present the first case of a hybrid endovascular approach to a penetrating aortic ulcer on the left descending aorta with a right aortic arch and aberrant left innominate artery arising from an aneurysmal Kommerell's diverticulum. The patient also had bilateral common iliac artery aneurysms. The three-step procedure consisted of a carotid-carotid bypass, followed by endovascular exclusion of the ulcer and the aneurysmal Kommerell's diverticulum, and then completion by covering the iliac aneurysms. The patient had no complications at 18 months after surgery. In such rare configurations, endovascular repair is a safe therapeutic option.

  20. Screening for aortic aneurysm after treatment of coarctation.

    Hoffman, James L; Gray, Robert G; LuAnn Minich, L; Wilkinson, Stephen E; Heywood, Mason; Edwards, Reggie; Weng, Hsin Ti; Su, Jason T


    Isolated coarctation of the aorta (CoA) occurs in 6-8 % of patients with congenital heart disease. After successful relief of obstruction, patients remain at risk for aortic aneurysm formation at the site of the repair. We sought to determine the diagnostic utility of echocardiography compared with advanced arch imaging (AAI) in diagnosing aortic aneurysms in pediatric patients after CoA repair. The Congenital Heart Databases from 1996 and 2009 were reviewed. All patients treated for CoA who had AAI defined by cardiac magnetic resonance imaging (MRI), computed tomography (CT), or catheterization were identified. Data collected included the following: type, timing, and number of interventions, presence and time to aneurysm diagnosis, and mortality. Patients were subdivided into surgical and catheterization groups for analysis. Seven hundred and fifty-nine patients underwent treatment for CoA during the study period. Three hundred and ninety-nine patients had at least one AAI. Aneurysms were diagnosed by AAI in 28 of 399 patients at a mean of 10 ± 8.4 years after treatment. Echocardiography reports were available for 380 of 399 patients with AAI. The sensitivity of echocardiography for detecting aneurysms was 24 %. The prevalence of aneurysms was significantly greater in the catheterization group (p Aneurysm was also diagnosed earlier in the catheterization group compared with the surgery group (p = 0.02). Multivariate analysis showed a significantly increased risk of aneurysm diagnosis in patients in the catheterization subgroup and in patients requiring more than three procedures. Aortic aneurysms continue to be an important complication after CoA repair. Although serial echocardiograms are the test of choice for following-up most congenital cardiac lesions in pediatrics, our data show that echocardiography is inadequate for the detection of aneurysms after CoA repair. Because the time to aneurysm diagnosis was shorter and the risk greater in the

    The authors present the case of a peripheral aneurysmal lesion that developed in a newborn baby and was successfully treated by endovascular parent artery occlusion. Given the natural history of aneurysms, which are prone to rupture and to cause deleterious intracerebral hemorrhage, with high mortality rates, aggressive and early management (endovascular or surgical) is recommended.

  4. Risk of Cerebrovascular Events in Elderly Patients After Radiation Therapy Versus Surgery for Early-Stage Glottic Cancer

    Hong, Julian C.; Kruser, Tim J. [Department of Human Oncology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin (United States); Gondi, Vinai [Department of Human Oncology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin (United States); Central Dupage Hospital Cancer Center, Warrenville, Illinois (United States); Mohindra, Pranshu; Cannon, Donald M.; Harari, Paul M. [Department of Human Oncology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin (United States); Bentzen, Søren M., E-mail: [Department of Human Oncology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin (United States)


    Purpose: Comprehensive neck radiation therapy (RT) has been shown to increase cerebrovascular disease (CVD) risk in advanced-stage head-and-neck cancer. We assessed whether more limited neck RT used for early-stage (T1-T2 N0) glottic cancer is associated with increased CVD risk, using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Methods and Materials: We identified patients ≥66 years of age with early-stage glottic laryngeal cancer from SEER diagnosed from 1992 to 2007. Patients treated with combined surgery and RT were excluded. Medicare CPT codes for carotid interventions, Medicare ICD-9 codes for cerebrovascular events, and SEER data for stroke as the cause of death were collected. Similarly, Medicare CPT and ICD-9 codes for peripheral vascular disease (PVD) were assessed to serve as an internal control between treatment groups. Results: A total of 1413 assessable patients (RT, n=1055; surgery, n=358) were analyzed. The actuarial 10-year risk of CVD was 56.5% (95% confidence interval 51.5%-61.5%) for the RT cohort versus 48.7% (41.1%-56.3%) in the surgery cohort (P=.27). The actuarial 10-year risk of PVD did not differ between the RT (52.7% [48.1%-57.3%]) and surgery cohorts (52.6% [45.2%-60.0%]) (P=.89). Univariate analysis showed an increased association of CVD with more recent diagnosis (P=.001) and increasing age (P=.001). On multivariate Cox analysis, increasing age (P<.001) and recent diagnosis (P=.002) remained significantly associated with a higher CVD risk, whereas the association of RT and CVD remained not statistically significant (HR=1.11 [0.91-1.37,] P=.31). Conclusions: Elderly patients with early-stage laryngeal cancer have a high burden of cerebrovascular events after surgical management or RT. RT and surgery are associated with comparable risk for subsequent CVD development after treatment in elderly patients.

  5. Fluid-structure interaction of a patient-specific abdominal aortic aneurysm treated with an endovascular stent-graft.

    Molony, David S


    BACKGROUND: Abdominal aortic aneurysms (AAA) are local dilatations of the infrarenal aorta. If left untreated they may rupture and lead to death. One form of treatment is the minimally invasive insertion of a stent-graft into the aneurysm. Despite this effective treatment aneurysms may occasionally continue to expand and this may eventually result in post-operative rupture of the aneurysm. Fluid-structure interaction (FSI) is a particularly useful tool for investigating aneurysm biomechanics as both the wall stresses and fluid forces can be examined. METHODS: Pre-op, Post-op and Follow-up models were reconstructed from CT scans of a single patient and FSI simulations were performed on each model. The FSI approach involved coupling Abaqus and Fluent via a third-party software - MpCCI. Aneurysm wall stress and compliance were investigated as well as the drag force acting on the stent-graft. RESULTS: Aneurysm wall stress was reduced from 0.38 MPa before surgery to a value of 0.03 MPa after insertion of the stent-graft. Higher stresses were seen in the aneurysm neck and iliac legs post-operatively. The compliance of the aneurysm was also reduced post-operatively. The peak Post-op axial drag force was found to be 4.85 N. This increased to 6.37 N in the Follow-up model. CONCLUSION: In a patient-specific case peak aneurysm wall stress was reduced by 92%. Such a reduction in aneurysm wall stress may lead to shrinkage of the aneurysm over time. Hence, post-operative stress patterns may help in determining the likelihood of aneurysm shrinkage post EVAR. Post-operative remodelling of the aneurysm may lead to increased drag forces.

  7. Endovascular repair of ruptured aneurysm arising from fenestration of the horizontal segment of the anterior cerebral artery: case report.

    Yoshida, Masahiro; Ezura, Masayuki; Sasaki, Kazuto; Chonan, Masashi; Mino, Masaki


    A 50-year-old man presented with an aneurysm arising from a fenestration of horizontal portion (A(1)) of the anterior cerebral artery manifesting as subarachnoid hemorrhage. Coil embolization was conducted and the aneurysm was occluded easily. Most reported cases of these types of aneurysms underwent direct surgery. Aneurysm arising from the A(1) fenestration is rare, but the present case shows that coil embolization can be an effective treatment modality. Three-dimensional rotational angiography and aneurysmography were helpful to characterize this complicated vascular structure.

  9. Impact of general versus epidural anesthesia on early post-operative cognitive dysfunction following hip and knee surgery

    Mandal Sripurna


    Full Text Available Background : Post-operative cognitive dysfunction is the subtle cerebral complication temporally seen following surgery. The aim of this study was to compare the influence of either general anesthesia (GA or epidural anesthesia (EA on the early post-operative neurocognitive outcome in elderly (>59 years subjects undergoing hip and knee surgery. Methods : A total of 60 patients were recruited in a prospective, randomized, parallel-group study, comparable by age and sex. They were enrolled and randomized to receive either EA (n = 30 or GA (n = 30. All of them were screened using the Mini Mental State Examination (MMSE, with components of the Kolkata Cognitive Screening Battery. The operated patients were re-evaluated 1 week after surgery using the same scale. The data collected were analyzed to assess statistical significance. Results : We observed no statistical difference in cognitive behavior in either group pre-operatively, which were comparable with respect to age, sex and type of surgery. Grossly, a significant difference was seen between the two groups with respect to the perioperative changes in verbal fluency for categories and MMSE scores. However, these differences were not significant after the application of the Bonferroni correction for multiple analyses, except the significant differences observed only in the MMSE scores. Conclusions : We observed a difference in cognitive outcome with GA compared with EA. Certain aspects of the cognition were affected to a greater extent in this group of patients undergoing hip and knee surgery.

  10. Intraoperative and early postoperative complications using the buccal fat pad during cleft palate surgery in East Indonesia

    Eveline Vere Konijnendijk


    Full Text Available Six baby’s with cleft are born in Indonesia every hour. There is no standardized treatment of cleft in East Indonesia. Closure is an important aspect during cleft lip and palate surgery. Various techniques have been advocated to gain tissue for closure of cleft area. Mostly these techniques may only provide a small amount of additional length. For lager defects they may be use the local flaps or the buccal fat pad flap. The aim of this study is gain more information about intraoperative and early postoperative complications using the buccal fat pat during cleft palate surgery in East Indonesia. The mouth can be divided in six parts therefor the LAHSAL index will be used. This LAHSAL system is a diagrammatic classification of cleft lip and palate. The LAHSAL system is being used for this study as this system classifies the cleft primarily on location and also on the cleft being complete or incomplete, which can be significant for the research. After diagnosis and classification, the following patient data was obtained: patient age, weight, gender, type of surgery (primary or following, i.e. when the surgery is a correction of a previous treatment, if a bone graft is needed for closure, history of maxillofacial surgery or orthodontics, operation technique, operation duration, type of an aesthesia (local or general, radiographical records and light photos. These data were collected during the pre-operative consultation, about 24 hours before surgery. It was the policy of the team to admit and see all patients one day prior to surgery for counselling, postoperative instructions and evaluating the patient's facial defect.

    Objective To investigate the value and prognosis of ruptured abdominal aoritc aneurysm (RAAA) surgery.Methods Nineteen cases of RAAA undergoing surgical treatment in our hospital from June 1979 to May 2000 were studied. The value and prognosis of RAAA sugery were judged by preoperative risk factors, complicated diseases, general conditions, blood biochemistry examination and multiorgan disfunction(MOD)score.Results Ten cases survived postoperatively with operative mortality of 47.4%. Significant differences between the surviving and deceased patients were found only with regard to pre-existing coronary heart disease and myocardial infarction (P<0.05). There were significant differences between two groups in peroperative hemoglobin, RBC count, blood urea and creatinine, severe hypotension, respiratory failure, and coma(P<0.05). All patients with a postoperative 48 h MOD score equal to 5 died. The mortality of the patients with a MOD score 4 lowered down following the score decreasing, and all patients with the score 1 survived. Conclusions Surgery treatment of RAAA was the unique selection of saving these patients. Postoperative death was mainly related with multi-organ disfunction resulted from hemorragic shock. The mortality of the patients with a postoperative 48 h MOD score over 4 was so high that the value of continuous treatment should be considered.%目的 探讨腹主动脉瘤破裂外科治疗的价值和预后。方法 分析我院自1979年6月~2000年5月经外科手术治疗的腹主动脉瘤破裂19例,通过术前高危因素、合并疾病、术前状况和血液生化检查以及多器官系统功能衰竭评分(MOD Score),对腹主动脉瘤破裂外科治疗的价值和预后进行判断。结果 术后存活10例,手术死亡率47.4%。术前冠心病和心肌缺血、心肌梗死二项指标,在存活组与死亡组间比较有显著性差异(P<0.05)。在术前血红蛋白、红细胞数、血肌酐、

    Full Text Available Clinical case of high thin-wall cystic limited filtering bleb needling revision in the early post-op period after trabeculectomy with sinusotomy accompanied by toxic keratopathy is presented. Optical coherence tomography (OCT demonstrated that filtering bleb height was 2700 μm and bleb wall thickness was 70 μm. Bleb needling revision with its lateralwall dissection and subconjunctival injection of dexamethasone, fluorouracil, and ranibizumab near to the bleb site was performed. In 1.5 hours after the procedure, bleb height decreased to 550 μm (by 5 times while bleb wall thickness increased up to 100 μm. Topical antibacterial, steroid, and non-steroid anti-inflammatory therapy was recommended. The next day IOP level reduced from 11 mm Hg to 4.5 mm Hg. It was accompanied by choroidal effusion that was managed conservatively with cycloplegic agents (drops and injections for 3 days. On day 6, central corneal edema affecting all layers, Descemet’s membrane folds, and ocular hypertension were revealed. Metabolic therapy resolved corneal edema within 3 days. Re-needling bleb revision decreased IOP level to 6.2 mm Hg. This resulted in transient Descemet’s membrane folds. This paper describes filtering bleb needling revision with its lateral wall dissection and anti-inflammatory, cytostatic, and anti-VEGF agents use to prolong glaucoma filtering surgery effect in excessive scarring. The procedure was accompanied by toxic corneal endothelium decompensation with corneal edema and Descemet’s membrane folds treated with active metabolic therapy.

    Martín-Pérez, Jesica; Delgado-Plasencia, Luciano; Bravo-Gutiérrez, Alberto; Lorenzo-Rocha, Nieves; Burillo-Putze, Guillermo; Medina-Arana, Vicente


    Recurrent gallstone ileus is an uncommon mechanical intestinal obstruction secondary to occlusion of the intestine by an intraluminal biliary calculus. Female, 75 years old, ischaemic heart disease (stent), arrived in our department complaining of abdominal pain and vomiting. Computed tomography showed gallstone ileus. The patient underwent an enterotomy with gallstone removal. Three months later, the patient came back with the same clinical symptoms and signs. A new computed tomography highlighted a gallstone ileus again. Enterolithotomy and gallstone removal, cholecystectomy and closure of cholecystoduodenal fistula were performed. The patient had a prolonged hospital stay due to the development of congestive heart failure. Case 2. Male, 71 years old, ischaemic heart disease and aortocoronary bypass, seen in our department complaining of vomiting. Computed tomography showed aerobilia and gallstone ileus. The patient underwent an urgent enterolithotomy. Seven months later, the patient came back with the same clinical symptoms and signs. Computed tomography showed a new gallstone ileus. An enterotomy and gallstone removal, cholecystectomy and closure of cholecystoduodenal fistula were performed. The patient died due to multi-organ failure in post-surgery period. In the elderly patients with concomitant medical illnesses with the risk of a second laparotomy, it is justifiable to reconsider the definitive repair in the treatment of gallstone ileus. The enterolithotomy in acute phase followed by early cholecystectomy (4-8 weeks) may be a safe method for eliminating, not only the possibility of recurrent gallstone ileus, and probably the need for a second laparotomy, but also the exceptional possibility of developing a gallbladder carcinoma.

  14. 3. Early outcomes of minimally invasive versus conventional mitral valve surgery in mitral valve diseases. A single institutional experience

    E. Nourelden


    Full Text Available Minimally invasive techniques in cardiac surgery gained popularity due to many advantages like less postoperative pain, minimal blood loss, less hospital stay, less cost. Minimally invasive mitral valve surgery through right anterolateral mini thoracotomy became safe technique. In our study we compared mini-MV surgery with conventional technique regarding cross clamp time, bypass time, total blood loss, reopening for bleeding, and hospital and ICU length of stay. In our institution between 2010 and 2015, 147patients underwent minimally invasive mitral surgery through right lateral minithoracotomy 8 cm incision and 118 patient underwent conventional mitral valve surgery through median sternotomy in minimally invasive technique: mean age was 38 ± 20 vs 59 ± 21, 70.7% were female (n = 104 vs 39.8% (n = 47, 23.8% were associated with tricuspid valve regurgitation (n = 33 vs 55% in conventional technique (n = 65, 0.08% were able to use endovascular clamp (n = 12, mean Euroscore predected risk of mortality 14.7 ± 13.6% vs 8.7 ± 10.9%.

    The aim of this study is to determine whether surgery offers protection against early subtalar arthrodesis in displaced intraarticular calcaneal fractures. Systematic review and meta-analysis: searches of electronic databases 1980 to August 2014, checking of reference lists, hand searching of journals, and contact with experts. Randomized controlled trials (RCTs) in which surgical treatment was compared with nonsurgical treatment of displaced intra-articular calcaneal fractures from 1980 to 2014. The modified Jadad scale was used for trial quality and effective data were pooled for meta-analysis. Study results related to early subtalar arthrodesis were extracted and risk assessment was combined with surgical treatment and nonsurgical treatment. The primary analysis included 4 studies and 966 participants. The estimated overall risk ratio was 4.40 (95% confidence interval 2.67-7.39), indicating the incidence of early subtalar arthrodesis in nonsurgical group is 4.4 times the surgical group. The results showed that surgical treatment was superior to nonsurgical treatment in protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures (Z = 5.600, P < 0.001).Surgery offers protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures.

    Background As an alternative to open aneurysm repair,endovascular aortic repair(EVAR)has been applied to ruptured abdominal aortic aneurysm(rAAA).The aim of this study was to evaluate the immediate and long-term outcomes of EVAR for rAAA.Methods From July 1997 to September 2007,20 men and six women with rAAA(median age,68 years)were treated with EVAR.Most patients with suspected rAAA underwent emergency computed tomographic angiography(CTA).The procedure was performed under general or local anesthesia.Endovascular clamping was attempted in hemodynamically unstable patients.Bifurcated endografts and aorto-uni-iliac(AUI)endografts with crossover bypass were used.Patients had CT scan prior to discharge,3,6,12 months after discharge,and annually thereafter.Results Time between diagnosis and EVAR ranged from 1 hour to 5 days.EVAR was performed under general anesthesia in 21 patients,and under local anesthesia in five patients.Endovascular aortic clamping was performed in four patients.There was no conversion to open surgery during EVAR.Stent-graft insertion was successful in all patients.One patient died during EVAR from acute myocardial infarction.Ten patients had systolic blood pressure<80 mm Hg.Eleven patients received a blood transfusion.Mean aneurysm size was(47c12)mm.Mean ICU stay was(8±3)days,mean hospital stay(18±6)days,and mean procedure time(120±32)minutes.The 30-day mortality was 23%(6/26patients),and major morbidity 35%(9/26 patients).Early endoleak occurred in 8/26 patients(31%).The mean follow-up was(18±7)months.No patient demonstrated migration of the stent-graft.Conclusions EVAR is a safe and effective option for treatment of acute rAAA,independent of the patient's general condition.Immediate and mid-term outcomes are favorable,but long-term outcome is unknown.Multi-center studies are necessary to establish the role of EVAR for rAAA.

  19. Combined surgical and endovascular management of a giant fusiform PCA aneurysm in a pediatric patient. A case report.

    Shin, S H; Choi, I S; Thomas, K; David, C A


    Treatment of intracranial giant aneurysms presents is challenging. In the case of pediatric giant aneurysm, more challenges arise. We describe our experience with a 17-year-old pediatric patient who presented with severe headache. She was diagnosed as having a giant fusiform aneurysm at the right P1-P2-Pcom junction. The aneurysm was treated with superficial temporal artery-posterior cerebral artery bypass and subsequent coil embolization of the aneurysm with parent artery occlusion. The patient had an excellent outcome at one-year follow-up. Our case suggests a combined approach of surgical and endovascular management may yield a better outcome than surgery or endovascular management alone in the treatment of pediatric giant aneurysm.

    Intracranial infectious aneurysms in the pediatric population are rare. Although surgery has been the traditional treatment of ruptured pediatric infectious aneurysms, endovascular coil embolization has become an attractive alternative due to its low rate of morbidity and mortality. A 9-year-old boy with a significant medical history of aortic valve replacement, antibiotic-treated infective endocarditis, and multiple embolic cerebral infarcts presented with a high-grade intraventricular hemorrhage due to the rupture of a large infectious proximal posterior circulation aneurysm. Computed tomography and cerebral angiogram demonstrated a right crural/ambient cistern hematoma and an associated infectious aneurysm of the right proximal posterior cerebral artery. The ruptured infectious aneurysm was coil-embolized with hydrogel-coated platinum coils without sacrifice of the distal parent artery. The aneurysm was completely occluded, and the patient regained all neurological function. Ruptured infectious aneurysms in the pediatric population occur despite aggressive medical therapy. Patients with infective endocarditis and embolic infarcts should be followed closely due to the risk of major hemorrhagic events, including aneurysm rupture. Hybrid coil embolization of ruptured infectious aneurysms with preservation of the distal parent artery is exceedingly rare and effective in the management of ruptured infectious aneurysms in the pediatric population.

  1. Endovascular strategy for unruptured cerebral aneurysms

    Mangiafico, S., E-mail: [Interventional Neuroradiology Unit, Careggi University Hospital, Florence (Italy); Guarnieri, G., E-mail: [Neuroradiology Service, Cardarelli Hospital, Naples (Italy); Consoli, A., E-mail: [Interventional Neuroradiology Unit, Careggi University Hospital, Florence (Italy); Ambrosanio, G., E-mail: [Neuroradiology Service, Cardarelli Hospital, Naples (Italy); Muto, M., E-mail: [Neuroradiology Service, Cardarelli Hospital, Naples (Italy)


    The treatment of unruptured intracranial aneurysms (UIAs) remains complex and not clearly defined. While for ruptured intracranial aneurysms the management and the treatment option (surgery or endovascular treatment) are well defined by several trials, for asymptomatic UIAs the best management is still currently uncertain. The rationale to treat an UIA is to prevent the rupture and its consequent SAH and all complications derived from hemorrhage or reduce/eliminate neurological palsy. Although this statement is correct, the indication to treat an UIA should be based on a correct balance between the natural history of UIA and treatment risk. Patient's clinical history, aneurysm characteristics, and strategy management influence the natural history of UIAs and treatment outcomes. In the last 10 years and more, two important large multicenter studies were performed in order to analysis of all these factors and to evaluate the best treatment option for UIAs. The aim of this paper is to try to synthesize the possible indications to the endovascular treatment (EVT), when and how to treat an UIA.

  2. Risk factors and consequences of unexpected trapping for ruptured anterior communicating artery aneurysms

    Hitoshi Fukuda


    Full Text Available Background: While clipping cerebral aneurysms at the neck is optimal, in some cases this is not possible and other strategies are necessary. The purpose of this study was to describe the incidence, risk factors, and outcomes for inability to clip reconstruct ruptured anterior communicating artery (ACoA aneurysms. Methods: Of the 70 cases of ruptured ACoA aneurysms between January 2006 and December 2013, our institutional experience revealed four cases of small ACoA aneurysms that had been considered clippable prior to operation but required trapping. When a unilateral A2 segment of anterior cerebral artery (ACA was compromised by trapping, revascularization was performed by bypass surgery. Clinical presentation, angiographic characteristics, operative approach, intraoperative findings, and treatment outcomes were assessed. Results: Very small aneurysm under 3 mm was a risk factor for unexpected trapping. The reason for unexpected trapping was laceration of the aneurysmal neck in two cases, and lack of clippaple component due to disintegration of entire aneurysmal wall at the time of rupture in the others. Aneurysms with bilateral A1 were treated with sole trapping through pterional approach in two cases. The other two cases had hypoplastic unilateral A1 segment of ACA and were treated with combination of aneurysm trapping and revascularization of A2 segment of ACA through interhemispheric approach. No patients had new cerebral infarctions of cortical ACA territory from surgery. Cognitive dysfunction was observed in three cases, but all patients became independent at 12-month follow up. Conclusions: Unexpected trapping was performed when ruptured ACoA aneurysms were unclippable. Trapping with or without bypass can result in reasonable outcomes, with acceptable risk of cognitive dysfunction.

Methods Seventy intracranial aneurysm ruptured patients who received operation were randomly divided into group A, which all received continuous lumbar cistern drainage early after operation , and group B, which all received continuous lumbar cistern drainage one week after operation. The incidences of early - stage complications both the two groups were compared. Results The incidences of communicating hy-drocephalus, cerebral angio spasm, leakage of cerebrospinal fluid of group A are all less than group B (P0.05). Conclusion Doing continuous lumbar cistern drainage early after operation for intracranial aneurysm ruptured patients can decrease the incidences of communicating hydrocephalus, cerebral angio spasm, leakage of cerebrospinal fluid safely.

    Garrido-García, Luis M; Morán-Villaseñor, Edna; Yamazaki-Nakashimada, Marco A; Cravioto, Patricia; Galván, Fernando


    One of the most important complications of Kawasaki disease is the development of giant coronary aneurysms. Risk factors for their development are still not clear. A retrospective analysis was conducted at the National Institute of Paediatrics in Mexico City, Mexico. It included all patients with a diagnosis of acute Kawasaki disease between August, 1995 and August, 2015. Clinical and laboratory findings, as well as echocardiographic measurements, were recorded. Patients with giant coronary aneurysms (z-score⩾10) were compared with the rest of the patients. A value of pKawasaki disease. Of them, 34 developed giant coronary aneurysms during the acute stage of the disease. In the multivariate analysis, patients younger than 1 year, those with a higher duration of illness at the time of diagnosis, and those who received additional intravenous immunoglobulin showed a significantly higher frequency of giant coronary aneurysms. One of the main factors associated with the development of giant coronary aneurysms was the delay in the diagnosis of Kawasaki disease. This finding highlights the importance of maintaining a high suspicion of the disease, which would enable an early diagnosis and prompt treatment and decrease the risk for developing giant coronary aneurysms.

  6. Early Healing Events after Periodontal Surgery: Observations on Soft Tissue Healing, Microcirculation, and Wound Fluid Cytokine Levels

    Kaner, Doğan; Soudan, Mouaz; Zhao, Han; Gaßmann, Georg; Schönhauser, Anna; Friedmann, Anton


    Early wound healing after periodontal surgery with or without enamel matrix derivative/biphasic calcium phosphate (EMD/BCP) was characterized in terms of soft tissue closure, changes of microcirculation, and expression of pro- and anti-inflammatory cytokines in gingival crevicular fluid/wound fluid (GCF/WF). Periodontal surgery was carried out in 30 patients (18 patients: application of EMD/BCP for regeneration of bony defects; 12 patients: surgical crown lengthening (SCL)). Healthy sites were observed as untreated controls. GCF/WF samples were collected during two post-surgical weeks. Flap microcirculation was measured using laser Doppler flowmetry (LDF). Soft tissue healing was evaluated after two weeks. GCF/WF levels of interleukin 1β (IL-1β), tumour necrosis factor (TNF-α), IL-6, and IL-10 were determined using a multiplex immunoassay. Surgery caused similar reductions of flap microcirculation followed by recovery within two weeks in both EMD/BCP and SCL groups. GCF/WF and pro-inflammatory cytokine levels were immediately increased after surgery, and returned only partially to baseline levels within the two-week observation period. Levels of IL-10 were temporarily reduced in all surgical sites. Flap dehiscence caused prolonged elevated levels of GCF/WF, IL-1β, and TNF-α. These findings show that periodontal surgery triggers an immediate inflammatory reaction corresponding to the early inflammatory phase of wound healing, and these inflammation measures are temporary in case of maintained closure of the flap. However, flap dehiscence causes prolonged inflammatory exudation from the periodontal wound. If the biological pre-conditions for periodontal wound healing are considered important for the clinical outcome, care should be taken to maintain primary closure of the flap. PMID:28134829

  7. Elective visceral hybrid repair of type III thoracoabdominal aortic aneurysm

    Marjanović Ivan


    Full Text Available Introduction. According to the classification given by Crawford et al. type III thoracoabdominal aortic aneurysm (TAAA is dilatation of the aorta from the level of the rib 6 to the separation of the aorta below the renal arteries, capturing all the visceral branch of aorta. Visceral hybrid reconstruction of TAAA is a procedure developed in recent years in the world, which involves a combination of conventional, open and endovascular aortic reconstruction surgery at the level of separation of the left subclavian artery to the level of visceral branches of aorta. Case report. We presented a 75-years-old man, with elective visceral hybrid reconstruction of type III TAAA. Computerized scanning (CT angiography of the patient showed type III TAAA with the maximum transverse diameter of aneurysm of 92 mm. Aneurysm started at the level of the sixth rib, and the end of the aneurysm was 1 cm distal to the level of renal arteries. Aneurysm compressed the esophagus, causing the patient difficulty in swallowing act, especially solid food, and frequent back pain. From the other comorbidity, the patient had been treated for a long time, due to chronic obstructive pulmonary disease and hypertension. In general endotracheal anesthesia with epidural analgesia, the patient underwent visceral hybrid reconstruction of TAAA, which combines classic, open vascular surgery and endovascular procedures. Classic vascular surgery is visceral reconstruction using by-pass procedure from the distal, normal aorta to all visceral branches: celiac trunk, superior mesenteric artery and both renal arteries, with ligature of all arteries very close to the aorta. After that, by synchronous endovascular technique a complete aneurysmal exclusion of thoracoabdominal aneurysm with thoracic stent-graft was performed. The postoperative course was conducted properly and the patient left the Clinic for Vascular Surgery on postoperative day 21. Control CT, performed 3 months after the surgery

  8. The 'Sphere': A Dedicated Bifurcation Aneurysm Flow-Diverter Device.

    Peach, Thomas; Cornhill, J Frederick; Nguyen, Anh; Riina, Howard; Ventikos, Yiannis


    We present flow-based results from the early stage design cycle, based on computational modeling, of a prototype flow-diverter device, known as the 'Sphere', intended to treat bifurcation aneurysms of the cerebral vasculature. The device is available in a range of diameters and geometries and is constructed from a single loop of NITINOL(®) wire. The 'Sphere' reduces aneurysm inflow by means of a high-density, patterned, elliptical surface that partially occludes the aneurysm neck. The device is secured in the healthy parent vessel by two armatures in the shape of open loops, resulting in negligible disruption of parent or daughter vessel flow. The device is virtually deployed in six anatomically accurate bifurcation aneurysms: three located at the Basilar tip and three located at the terminus bifurcation of the Internal Carotid artery (at the meeting of the middle cerebral and anterior cerebral arteries). Both steady state and transient flow simulations reveal that the device presents with a range of aneurysm inflow reductions, with mean flow reductions falling in the range of 30.6-71.8% across the different geometries. A significant difference is noted between steady state and transient simulations in one geometry, where a zone of flow recirculation is not captured in the steady state simulation. Across all six aneurysms, the device reduces the WSS magnitude within the aneurysm sac, resulting in a hemodynamic environment closer to that of a healthy vessel. We conclude from extensive CFD analysis that the 'Sphere' device offers very significant levels of flow reduction in a number of anatomically accurate aneurysm sizes and locations, with many advantages compared to current clinical cylindrical flow-diverter designs. Analysis of the device's mechanical properties and deployability will follow in future publications.

  9. Virtual Reality Cerebral Aneurysm Clipping Simulation With Real-time Haptic Feedback

    Alaraj, Ali; Luciano, Cristian J.; Bailey, Daniel P.; Elsenousi, Abdussalam; Roitberg, Ben Z.; Bernardo, Antonio; Banerjee, P. Pat; Charbel, Fady T.


    Background With the decrease in the number of cerebral aneurysms treated surgically and the increase of complexity of those treated surgically, there is a need for simulation-based tools to teach future neurosurgeons the operative techniques of aneurysm clipping. Objective To develop and evaluate the usefulness of a new haptic-based virtual reality (VR) simulator in the training of neurosurgical residents. Methods A real-time sensory haptic feedback virtual reality aneurysm clipping simulator was developed using the Immersive Touch platform. A prototype middle cerebral artery aneurysm simulation was created from a computed tomography angiogram. Aneurysm and vessel volume deformation and haptic feedback are provided in a 3-D immersive VR environment. Intraoperative aneurysm rupture was also simulated. Seventeen neurosurgery residents from three residency programs tested the simulator and provided feedback on its usefulness and resemblance to real aneurysm clipping surgery. Results Residents felt that the simulation would be useful in preparing for real-life surgery. About two thirds of the residents felt that the 3-D immersive anatomical details provided a very close resemblance to real operative anatomy and accurate guidance for deciding surgical approaches. They believed the simulation is useful for preoperative surgical rehearsal and neurosurgical training. One third of the residents felt that the technology in its current form provided very realistic haptic feedback for aneurysm surgery. Conclusion Neurosurgical residents felt that the novel immersive VR simulator is helpful in their training especially since they do not get a chance to perform aneurysm clippings until very late in their residency programs.

  10. Blister-like aneurysms of the anterior communicating artery: a retrospective review of diagnosis and treatment in five patients.

    Andaluz, Norberto; Zuccarello, Mario


    Blood blister-like aneurysms are small hemispherical bulges from the dorsomedial wall of the internal carotid artery that resemble berry aneurysms but differ in their clinical and surgical features. On the basis of our literature review, blister-like aneurysms have been reported to occur only at nonbranching sites of the dorsomedial internal carotid artery. In this report on our series of five patients, we describe blister-like aneurysms of the anterior communicating artery (AComA) and discuss important diagnostic and therapeutic aspects unique to them. In our retrospective review of 719 patients with nontraumatic subarachnoid hemorrhage admitted to our service from 1998 to 2003, 181 (25.17%) patients harbored AComA aneurysms. Five (2.76%) patients (four women, one man) had blister-like aneurysms that were recognized at the time of surgery. Initial digital subtraction angiography was diagnostic in only one patient. A second digital subtraction angiogram was diagnostic in one patient but failed to reveal an aneurysm in the remaining three patients; these were eventually diagnosed by computed tomographic angiography. All aneurysms were clipped. At the time of surgery, the aneurysms arose from the horizontal portion of the AComA without any involvement of the branches of the anterior cerebral artery. All presented as blister-like aneurysms that were thin-walled and lacking a surgical neck. On dissection, two of the lesions ruptured. All lesions were treated with straight fenestrated clips through the A1-AComA junction, thus remodeling the AComA. No delayed rupture was noted at the time of the last follow-up evaluation. At the time of discharge, outcomes were good in two patients, fair in two, and poor in the remaining patient. Blister-like aneurysms constitute technically challenging lesions that may occur at the AComA. Computed tomographic angiography is valuable in diagnosis. Blister-like aneurysms should be suspected when digital subtraction angiography findings

  11. Congenital left ventricular aneurysm coexisting with left ventricular non-compaction in a newborn.

    Ootani, Katsuki; Shimada, Jun; Kitagawa, Yosuke; Konno, Yuki; Miura, Fumitake; Takahashi, Toru; Ito, Etsuro; Ichinose, Kouta; Yonesaka, Susumu


    Described herein is the case of a rare combination of congenital left ventricular (LV) aneurysm and left ventricular non-compaction (LVNC) in a newborn. The patient developed refractory heart failure soon after birth and died at 5 months of age. The etiology of both congenital LV aneurysm and LVNC seems to be maldevelopment of the ventricular myocardium during early fetal life. Treatment should be individually tailored depending on clinical severity, and treatment options are limited. Given that this combination of congenital LV aneurysm and LVNC is significantly associated with poor prognosis, it appears that patients with congenital LV aneurysm and LVNC are candidates for early, aggressive intervention, including surgical aneurysmectomy and evaluation for transplantation. It is important to be aware of this combination of congenital LV aneurysm and LVNC, and to make earlier decisions on therapeutic strategy.

  12. Endovascular management of intracranial blister aneurysms: spectrum and limitations of contemporary techniques.

    Ashour, Ramsey; Dodson, Stephen; Aziz-Sultan, M Ali


    Intracranial blister aneurysms are rare lesions that are notoriously more difficult to treat than typical saccular aneurysms. High complication rates associated with surgery have sparked considerable interest in endovascular techniques, though not well-studied, to treat blister aneurysms. To evaluate our experience using various endovascular approaches to treat blister aneurysms. All consecutive blister aneurysms treated using an endovascular approach by the study authors over a 3-year period were retrospectively analyzed. A literature review was also performed. Nine patients with blister aneurysms underwent 11 endovascular interventions. In various combinations, stents were used in 8/11, coils in 5/11, and Onyx in 3/11 procedures. At mean angiographic follow-up of 200 days, 8/9 aneurysms were completely occluded by endovascular means alone requiring no further treatment and 1/9 aneurysms required surgical bypass/trapping after one failed surgical and two failed endovascular treatments. At mean clinical follow-up of 416 days, modified Rankin Scale scores were improved in six patients, stable in two, and worsened in one patient. One complication occurred in 11 procedures (9%), resulting in a permanent neurologic deficit. No unintended endovascular parent vessel sacrifice, intraprocedural aneurysmal ruptures, antiplatelet-related complications, post-treatment aneurysmal re-ruptures, or deaths occurred. This series highlights both the spectrum and limitations of endovascular techniques currently used to treat blister aneurysms, including a novel application of stent-assisted Onyx embolization. Long-term follow-up and experience in larger studies are required to better define the role of endovascular therapy in the management of these difficult lesions.

  13. Recovery of immunological homeostasis positively correlates both with early stages of right-colorectal cancer and laparoscopic surgery.

    Ferri, Mario; Rossi Del Monte, Simone; Salerno, Gerardo; Bocchetti, Tommaso; Angeletti, Stefano; Malisan, Florence; Cardelli, Patrizia; Ziparo, Vincenzo; Torrisi, Maria Rosaria; Visco, Vincenzo


    Differences in postoperative outcome and recovery between patients subjected to laparoscopic-assisted versus open surgery for colorectal cancer (CRC) resection have been widely documented, though not specifically for right-sided tumors. We investigated the immunological responses to the different surgical approaches, by comparing postoperative data simultaneously obtained at systemic, local and cellular levels. A total of 25 right-sided CRC patients and controls were managed, assessing -in the immediate followup- the conventional perioperative parameters and a large panel of cytokines on plasma, peritoneal fluids and lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMC) tissue cultures. A general better recovery for patients operated with laparoscopy compared to conventional procedure, as indicated by the analysis of typical pre- and post-surgical parameters, was observed. The synchronous evaluation of 12 cytokines showed that preoperative plasma levels of the proinflammatory cytokines IL-6, IL-8, IL-1β, TNFα were significantly lower in healthy donors versus CRC patients and that such differences progressively increase with tumor stage. After surgery, the IL-6 and IL-8 increases were significantly higher in open compared to laparoscopic approach only in CRC at early stages. The postsurgical whole panel of cytokine levels were significantly higher in peritoneal fluids compared to corresponding plasma, but with no significant differences depending on kind of surgery or stage of disease. Then we observed that, pre- compared to the corresponding post-surgery derived LPS-stimulated PBMC cultures, produced higher supernatant levels of the whole cytokine panel. In particular IL-6 in vitro production was significantly higher in PBMC derived from patients subjected to laparoscopic versus open intervention, but -again- only in CRC at early stages of disease. Our results thus show that laparoscopy compared to open right resection is associated with a

  15. Procalcitonin, interleukin 6 and systemic inflammatory response syndrome (SIRS): early markers of postoperative sepsis after major surgery.

    Mokart, D; Merlin, M; Sannini, A; Brun, J P; Delpero, J R; Houvenaeghel, G; Moutardier, V; Blache, J L


    Patients who undergo major surgery for cancer are at high risk of postoperative sepsis. Early markers of septic complications would be useful for diagnosis and therapeutic management in patients with postoperative sepsis. The aim of this study was to investigate the association between early (first postoperative day) changes in interleukin 6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) serum concentrations and the occurrence of subsequent septic complications after major surgery. Serial blood samples were collected from 50 consecutive patients for determination of IL-6, PCT and CRP serum levels. Blood samples were obtained on the morning of surgery and on the morning of the first postoperative day. Sixteen patients developed septic complications during the first five postoperative days (group 1), and 34 patients developed no septic complications (group 2). On day 1, PCT and IL-6 levels were significantly higher in group 1 (P-values of 0.003 and 0.006, respectively) but CRP levels were similar. An IL-6 cut-off point set at 310 pg ml(-1) yielded a sensitivity of 90% and a specificity of 58% to differentiate group 1 patients from group 2 patients. When associated with the occurrence of SIRS on day 1 these values reached 100% and 79%, respectively. A PCT cut-off point set at 1.1 ng ml(-1) yielded a sensitivity of 81% and a specificity of 72%. When associated with the occurrence of SIRS on day 1, these values reached 100% and 86%, respectively. PCT and IL-6 appear to be early markers of subsequent postoperative sepsis in patients undergoing major surgery for cancer. These findings could allow identification of postoperative septic complications.

  16. Right iliac arterial aneurysm in a 4-year-old girl who does not have a right external iliac artery.

    Lee, Jeong-Hwan; Oh, Chaeyoun; Youn, Joong Kee; Han, Ji-Won; Kim, Hyun-Young; Jung, Sung-Eun


    Pediatric arterial aneurysm is rare disease. Among them, idiopathic-congenital arterial aneurysm is extremely rare. This is a case report of right common iliac artery idiopathic aneurysm with absence of right external iliac artery. A 4-year-old girl who had been complaining of intermittent abdominal pain since 2 years prior presented with a right lower abdominal mass that had been palpable since 6 months prior. Abdominal CT revealed a 5.2 cm × 4.5 cm × 5.1 cm, right-sided, partially thrombosed, saccular, iliac artery aneurysm. She underwent to operation, aneurismal resection. A pathological examination confirmed that it was a true aneurysm, considering that all layers of the vascular wall were stretched with no deficit. The patient was discharged 3 days after the surgery without any complication. Five months passed since the surgery, and the patient is doing well without any abdominal or leg pain.

  17. Ductus arteriosus aneurysm with community-acquired methicillin-resistant Staphylococcus aureus infection and spontaneous rupture: a potentially fatal quandary.

    Stewart, Audra; Dyamenahalli, Umesh; Greenberg, S Bruce; Drummond-Webb, Jonathan


    We present the case of a 6-month-old previously healthy girl who presented with high fever, labored breathing, and an enlarged cardiac silhouette on her chest radiograph. Comprehensive evaluation discovered a ductus arteriosus aneurysm and pericardial effusion with methicillin-resistant Staphylococcus aureus bacteremia. Despite pericardiocentesis and appropriate intravenous antibiotics, there was rapid enlargement of the aneurysm and accumulation of echogenic material within the ductus arteriosus aneurysm. Infected aneurysm rupture was identified during emergency surgery. This infant also had vocal cord paresis, a likely complication of the surgery. The clinical course, diagnosis, and treatment of this patient are discussed. Infection of a ductus arteriosus or an infected ductal arteriosus aneurysm is a rare and potentially fatal clinical entity. In the era of increasing community-acquired methicillin-resistant S aureus infections, this is a diagnosis that requires a high index of suspicion.

    In this case we presented a patient who were admitted to surgery department with complaints of abdominal pain and nausea. There were no pathological findings on physical examination, direct abdominal x-ray, chest radiograph and biochemical parameters. At proximal of the celiac trunk, it was shown approximately 3x2 cm in size fusiform aneurysmal dilatation on the patient%u2019s abdominal ultrasonography and turbulence, arterial flow on the patient%u2019s abdominal doppler ultrasonography subsequently. In abdominal computed tomography we detected dense calcifications, dilatation and hypodensities that may belong to a thrombus in the lumen superior mesenteric vein (SMV. At the same time, approximately 3.5 cm segment of trunk celiak we observed aneurysm dilatation which reaching 2 cm at the widest point. Celiac trunk aneurysm is a rare cause of abdominal pain and often noticed after the complicated, thus it must always be kept in mind in the differential diagnosis.

    Objective.Electrolytic detachable coils (EDC) have been the main embolic materials for intracranial aneurysms.Liquid aneurysmal embolic materials represented by cellulose acetate polymer (CAP) are still in controversy.In this research,the embolization results and pathological reactions after embolization of canine aneurysmal models with EDC or CAP were observed and compared. Methods.The canine aneurysmal models constructed by anastomosis of venous pouches were randomly grouped.The aneurysms were respectively occluded with CAP and electrolytic detachable coils that was named by Wu electrolytic detachable coil (WEDC) and made by us.Angiogram follow ups were performed at 24 hour,2 week,and 2 month after embolization.The occluded aneurysms were dissected in each stage for light microscopic,electron microscopic,and histochemical research. Results.The effect of embolization was significantly better with WEDC than that with CAP ( χ 2=5.56,P< 0.05) .Post embolized complications such as aneurysm rupture and stenosis of parent arteries could only be found in CAP group.Pathological research showed that CAP mass could packed the aneurysms more densely than coils.Acute chemical damage of aneurysmal wall and inflammatory cell infiltration was prominently found in early stage after CAP embolization.Organization of thrombus inside aneurysms and formation of endothelial tissue over the orifices of aneurysmal necks could be found in both groups 2 months after embolization.But parts of coils might be exposed outside endothelial layer. Conclusions.EDC are still the most safe,efficient,and reliable instruments to embolize aneurysm.CAP should be improved further to solve the problem of strong chemical corrosion and difficulty in control before it is widely used.

    To describe CT features of mycotic aneurysms. We have retrospectively checked 10 patients diagnosed with mycotic aneurysm. Three revealed previously treated arteriosclerotic aneurysms, one was diabetic and had undergone a reno pancreatic transplant, and another presented advanced HIV infection. They all presented fever syndrome and eight exhibited leucocytosis. Mycotic aneurysm diagnosis was made by means of CT findings, clinical examination and positive hemo culture in all cases. Anatomopathological findings were available as confirmation for all four surgically treated patients. The CT scan was performed during arterial phase with spiral acquisition, without contrast and with endo venous administration of a contrast medium. Saccular aneurysms were found in seven patients (double aneurysms in the case of two), with seven of these being abdominal aneurysms (one retrocrural aortic,three infra renal aortic, and three iliac arteries) and two thoracic (aortic arch). In all three remaining patients, there was a pre-existing arteriosclerotic aneurysm (fusiform) and only incipient changes were observed in the adjacent fat. Perianeurysmatic soft-tissue was was noted in eight cases. Only two patients presented signs of tear (peri aneurysm hematoma and/or with contrast extravasation). In three cases, the calcium ring was disrupted. In two patients, absences were observed in other locations. In none of the cases was there gas in the aneurysm wall. Mycotic aneurysm is a rate entity, but must be considered in the evaluation of septic patients since it demands early diagnosis and treatment. In such patients, a CT finding of saccular aneurysm with adjacent soft-tissue mass, and associated with a positive hemo culture, is highly suggestive of this pathology. (Author) 9 refs.

    There are no approved Food and Drug Administration indications for pediatric auditory brainstem implant (ABI) surgery in the United States. Our prospective case series aims to determine the safety and feasibility of ABI surgery in pediatric patients age, 2.52 ± 0.39 years). Four patients underwent ABI surgery (age, 19.2 ± 3.43 months), including 4 primary procedures and 1 revision for device failure. Spontaneous device failure occurred in another subject postoperatively. No major/minor complications occurred, including cerebrospinal fluid leak, facial nerve injury, hematoma, and nonauditory stimulation. All subjects detected sound with environmental awareness, and several demonstrated babbling and mimicry. Poor durability of older implants underscores need for updated technology. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Aneurysms of the splenic artery which arise anomalously from the superior mesenteric artery are extremely rare but clinically important because of their life-threatening hemorrhage. Diagnostic imaging plays an important role in the diagnosis and conducting treatment strategy. The aim of this study was to evaluate the detection of anomalous splenic artery aneurysms with 3D contrast-enhanced MR angiography. 3D contrast-enhanced MR angiography was performed in six patients with anomalous splenic artery aneurysms. The mean diameter of six aneurysms was 3.9 cm. All of them were saccular and located at the origin of the splenic artery that arose anomalously from the root of the superior mesenteric artery. 3D contrast-enhanced MR angiography clearly demonstrated the aneurysm's location, size, morphology, visceral arterial variations, and was superior to DSA in three-dimensional display of the aneurysm and its relationship with surrounding vessels and organs. Two patients underwent open vascular surgery and three endovascular procedure. 3D contrast-enhanced MR angiography is a noninvasive and accurate technique for diagnosis of anomalous splenic artery aneurysms. Its 3D anatomic information is very helpful for treatment planning. It can be used as one of the first choice examinations for anomalous splenic artery aneurysms.

    Adult unilateral moyamoya disease with intracranial aneurysm is frequently reported in the literature, but there is much variation in its treatment. In this case report, we describe the time course and treatment regimen of a patient with moyamoya disease and review the literature regarding moyamoya disease with intracranial aneurysm. A 64-year-old man had untreated intracranial aneurysm and unilateral moyamoya disease for 10 years. He presented with sudden-onset right hemiparesis and aphasia due to a subcortical hemorrhage. He was admitted to the local neurosurgical unit, and upon resolution of symptoms, he was admitted to our hospital. A cerebral angiogram revealed the champagne bottleneck sign of the left carotid artery and obliteration of the top of the left intracranial carotid artery with a moyamoya phenomenon. Two unruptured intracranial aneurysms were identified in the anterior communicating artery(Acom A) and the right intracranial carotid artery(C3). We performed superficial temporal artery-middle cerebral artery anastomosis followed by aneurysmal neck clipping of the Acom A aneurysm. Postoperative imaging showed no new ischemic damage and improved cerebral blood flow. Although the patient experienced temporal worsening of aphasia, his function recovered a few months later and he was able to resume his normal daily life activities. The combination of direct bypass surgery and aneurysmal neck clipping might be a therapeutic option for hemorrhagic unilateral moyamoya disease with unruptured intracranial aneurysm.

  7. Robotic aortic surgery.

    Duran, Cassidy; Kashef, Elika; El-Sayed, Hosam F; Bismuth, Jean


    Surgical robotics was first utilized to facilitate neurosurgical biopsies in 1985, and it has since found application in orthopedics, urology, gynecology, and cardiothoracic, general, and vascular surgery. Surgical assistance systems provide intelligent, versatile tools that augment the physician's ability to treat patients by eliminating hand tremor and enabling dexterous operation inside the patient's body. Surgical robotics systems have enabled surgeons to treat otherwise untreatable conditions while also reducing morbidity and error rates, shortening operative times, reducing radiation exposure, and improving overall workflow. These capabilities have begun to be realized in two important realms of aortic vascular surgery, namely, flexible robotics for exclusion of complex aortic aneurysms using branched endografts, and robot-assisted laparoscopic aortic surgery for occlusive and aneurysmal disease.

    Background: This study was aimed at investigating clinical and histopathologic features of ipsilateral breast tumor recurrences (IBTR) and their effects on survival after breast conservation therapy. Methods: 1,400 patients who were treated between 1998 and 2007 and had breast-conserving surgery (BCS) for early breast cancer (cT1-2/N0-1/M0) were evaluated. Demographic and pathologic parameters, radiologic data, treatment, and follow-up related features of the patients were recorded. Results: 53 patients (3.8%) had IBTR after BCS within a median follow-up of 70 months. The mean age was 45.7 years (range, 27-87 years), and 22 patients (41.5%) were younger than 40 years. 33 patients (62.3%) had true recurrence (TR) and 20 were classified as new primary (NP). The median time to recurrence was shorter in TR group than in NP group (37.0 (6-216) and 47.5 (11-192) months respectively; p = 0.338). Progesterone receptor positivity was significantly higher in the NP group (p = 0.005). The overall 5-year survival rate in the NP group (95.0%) was significantly higher than that of the TR group (74.7%, p 20 mm), high grade tumor and triple-negative molecular phenotype along with developing TR negatively affected overall survival (hazard ratios were 4.2 (CI 0.98-22.76), 4.6 (CI 1.07-13.03), 4.0 (CI 0.68-46.10), 6.5 (CI 0.03-0.68), and 6.5 (CI 0.02- 0.80) respectively, p 2 cm), high grade, triple negative phenotype, and having true recurrence were identified as independent prognostic factors with a negative impact on overall survival in this dataset of patients with recurrent breast cancer. In conjunction with a more intensive follow-up program, the role of adjuvant therapy strategies should be explored further in young patients with large and high-risk tumors to reduce the risk of TR.

  12. Intracranial hemorrhage from undetected aneurysmal rupture complicating transphenoidal pituitary adenoma resection.

    Rustagi, Tarun; Uy, Edilfavia Mae; Rai, Mridula; Kannan, Subramanian; Senatus, Patrick


    We report a case of a 39-year-old man who presented with a nonfunctioning pituitary macroadenoma which extended into the suprasellar region. He underwent a transcranial resection of the tumor followed eight months later by transsphenoidal surgery for the residual tumor. Postoperatively he developed massive subarachnoid and intraventricular hemorrhage. A cerebral angiogram revealed a leaking anterior communicating artery aneurysm which was not seen on the computed tomography angiography and magnetic resonance angiography before the surgery. Complications of transsphenoidal surgery, particularly vascular hemorrhagic complications, and risk of rupture of undetected aneurysms are discussed.

    Maksić Milanko


    Full Text Available Background/Aim. To promote better treatment outcome, as well as economic benefit it is very important to find out patients with simultaneous occurrence of both aortic and arterial aneurysms. The aim of this prospective study was to determine the frequency and factors affecting femoropopliteal (F-P segment aneurysms appearance in patients with abdominal aortic aneurysms (AAA. Methods. This study included 70 patients who had underwent elective or urgent surgery of AAA from January 1, 2006 to December 31, 2007. After ultrasonographic examination of F-P segment, all the patients were divided into two groups - those with adjunctive F-P segment aneurysm (n = 20 and the group of 50 patients with no adjunctive F-P segment aneurysm. In both groups demographic characteristics (gender, age, risk factors (diabetes mellitus, elevated serum levels of cholesterol and triglycerides, arterial hypertension, smoking, obesity and cardiovascular comorbidity (cerebrovascular desease, ischemic heart desease were investigated. Results. Twenty (28.57% patients who had been operated on because of AAA, had adjunctive aneurysmal desease of F-P segment. Diabetes was no statistically significantly more present among the patients who, beside AAA, had adjunctive aneurismal desease of F-P segment (χ2 = 0.04; DF = 1; p > 0.05. Also, in both groups there was no statistically significant difference in gender structure (χ2 = 2. 05; DF = 2; p > 0.05, age (χ2 = 5. 46; DF = 1; p > 0.05, total cholesterol level (χ2 = 0.89; DF = 1; p > 0.05 and triglyceride (χ2 = 0.89; DF = 1; p > 0.05 levels, the presence of arterial hypertension (χ2 = 1.38; DF = 2; p > 0.05, smoking (χ2 = 1.74; DF = 1; p > 0.05, obesity (χ2 = 1.76; DF = 1; p > 0.05 and presence of cerebrovascular desease (χ2 = 2.34; DF = 1; p > 0.05. Conversly, ischemic heart desease was statistically significantly more present among the patients who, beside AAA, had adjunctive aneurismal desease of F-P segment (χ2 = 5

  14. Groin Swelling in a Four-Year-Old Boy: Primary Great Saphenous Vein Aneurysm.

    Çiçek, Mustafa Cüneyt; Çiçek, Ömer Faruk; Yalçınkaya, Adnan; Taşoğlu, İrfan


    Primary venous aneurysm, especially in pediatric population, is a very rare clinical entity. We report a case of primary great saphenous vein aneurysm in a 4-year-old boy. He was initially suspected of suffering from inguinal hernia because the soft mass was detected at the inguinal region when the patient was in the standing position, but color Doppler ultrasonography demonstrated the swelling to be a great saphenous vein aneurysm. We decided that surgery was the best option because of potential risk for thromboembolism. Copyright © 2015 Elsevier Inc. All rights reserved.

  15. Mycotic aneurysm in a child with history of coarctation of the aorta repair

    Restrepo, M Santiago; Turek, Joseph W; Reinking, Benjamin; Bergen, Nicholas Von


    A mycotic aneurysm is a rare condition occasionally seen in patients with a history of prior cardiac or vascular surgery. Here we report the presentation of a mycotic aneurysm in a pediatric patient at the site of prior aortic coarctation repair. This patient's initial presentation suggested rheumatologic or oncologic disease, and after diagnosis he continued to show evidence of splenic, renal and vascular injury distal to the mycotic aneurysm site while being treated with antibiotics. We discuss the diagnosis, treatment and management of this condition. PMID:24987262

    Zhari, Bouchra; Bellamlih, Habib; Boumdine, Hassan; Amil, Touriya; Bamous, Mehdi; En-Nouali, Hassan


    Left atrial appendage aneurysm is a very rare heart anomaly. It may be congenital or acquired, secondary to inflammatory or degenerative processes. Most cases are asymptomatic. The prevalence of these lesions in pediatric age has been very rarely reported. As it can cause potentially fatal arrhythmias or thrombus, surgery is required immediately after diagnosis. This study reports the case of a 14-year-old boy with rapidly progressive dyspnea, palpitations, sensation of repetitive dizziness and fainting, in whom congenital left atrial appendage aneurysm was detected. Diagnosis was based on coronary CTA data. The patient was successfully treated with surgical resection of the aneurysm.

  17. Giant right coronary artery aneurysm with unusual physiology: Role of intraoperative transesophageal echocardiography

    David M Orozco


    Full Text Available A 65-year-old woman presented with a history of dyspnea and atypical chest pain. She was diagnosed with a non-ST-segment elevation myocardial infarction due to a giant right coronary artery aneurysm. After a failed percutaneous embolization, she was scheduled for right coronary artery aneurysm resection, posterior descending artery revascularization and mitral valve repair. During the induction of anesthesia and institution of mechanical ventilation, the patient suffered cardiovascular collapse. The transesophageal echocardiographic examination revealed tamponade physiology owing to compression of the cardiac chambers by the unruptured aneurysm, which resolved with the sternotomy. The surgery was carried out uneventfully.

  18. Clip reconstruction of a large right MCA bifurcation aneurysm. Case report

    Giovani A.


    Full Text Available We report a case of complex large middle cerebral artery (MCA bifurcation aneurysm that ruptured during dissection from the very adherent MCA branches but was successfully clipped and the MCA bifurcation reconstructed using 4 Yasargill clips. Through a right pterional craniotomy the sylvian fissure was largely opened as to allow enough workspace for clipping the aneurysm and placing a temporary clip on M1. The pacient recovered very well after surgery and was discharged after 1 week with no neurological deficit. Complex MCA bifurcation aneurysms can be safely reconstructed using regular clips, without the need of using fenestrated clips or complex by-pass procedures.

  19. The management of very small/blister internal carotid artery aneurysms.

    Le Feuvre, David E J; Taylor, A G


    Blood blister aneuryms are uncommon lesions that have a poor natural history. Because there is no clear aneurysmal sac to treat they remain challenging lesions to manage whether the approach is endovascular or surgical. Although the management of intracranial cerebral aneurysms has changed subsequent to the results published by the ISAT trial, there still exist groups of aneurysms which do not lend themselves to endovascular management. There are recent reports of successful endovascular management using flow diverting approaches but experience is limited and relying on flow change may be insufficient to prevent re-rupture. Surgery when possible offers the advantage of immediate vessel wall reconstruction.

  1. Neurogenic pulmonary edema after rupture of intracranial aneurysm during endovascular coiling

    Ashish Bindra


    Full Text Available Neurogenic pulmonary edema (NPE is a well-known entity, occurs after acute severe insult to the central nervous system. It has been described in relation to different clinical scenario. However, NPE has rarely been mentioned after endovascular coiling of intracranial aneurysms. Here, we report the clinical course of a patient who developed NPE after aneurysmal rupture during endovascular surgery. There was significant cardiovascular instability possibly from stimulation of hypothalamus adjacent to the site of aneurysm. This case highlights the predisposition of minimally invasive procedures like endovascular coiling to life-threatening complications such as NPE.

  2. The hip fracture best practice tariff: early surgery and the implications for MRSA screening and antibiotic prophylaxis.

    Bryson, David J; Gulihar, Abhinav; Aujla, Randeep S; Taylor, Grahame J S


    In April 2010, the Department of Health introduced the hip fracture best practice. Among the clinical criteria required to earn remuneration is surgery within 36 h of admission. However, early surgery may mean that methicillin-resistant Staphylococcus aureus (MRSA) colonisation status is not known before surgery, and therefore, appropriate antibiotic prophylaxis may not be administered. In view of this, our department's policy is to administer an additional dose of teicoplanin to patients with unknown MRSA status along with routine antimicrobial prophylaxis. The purpose of this study was to provide a safe and effective antimicrobial prophylaxis for hip fracture patients. We prospectively collected details of demographics and antimicrobial prophylaxis for all patients admitted with a hip fracture in November 2011. This was repeated in February 2012 after an educational and advertising drive to improve compliance with departmental antimicrobial policy. Microbiology results were obtained from the hospital microbiology database. A cost-benefit analysis was undertaken to assess this regime. A total of 144 hip fracture patients were admitted during the 2 months. The average admission to surgery time was 32 h, and the average MRSA swab processing time was 35 h. 86 % of patients reached theatre with unknown MRSA status. Compliance with the departmental antimicrobial policy improved from 25 % in November 2011 to 76 % in February 2012. Potential savings of £ 40,000 were calculated. With best practice tariff resulting in 86 % of patients reaching theatre with unknown MRSA status, we advocate an additional single dose of teicoplanin to cover against possible MRSA colonisation.

  3. Surgery Should Complement Endocrine Therapy for Elderly Postmenopausal Women with Hormone Receptor-Positive Early-Stage Breast Cancer

    Olivier Nguyen


    Full Text Available Introduction. Endocrine therapy (ET is an integral part of breast cancer (BC treatment with surgical resection remaining the cornerstone of curative treatment. The objective of this study is to compare the survival of elderly postmenopausal women with hormone receptor-positive early-stage BC treated with ET alone, without radiation or chemotherapy, versus ET plus surgery. Materials and Methods. This is a retrospective study based on a prospective database. The medical records of postmenopausal BC patients referred to the surgical oncology service of two hospitals during an 8-year period were reviewed. All patients were to receive ET for a minimum of four months before undergoing any surgery. Results. Fifty-one patients were included and divided in two groups, ET alone and ET plus surgery. At last follow-up in exclusive ET patients (n=28, 39% had stable disease or complete response, 22% had progressive disease, of which 18% died of breast cancer, and 39% died of other causes. In surgical patients (n=23, 78% were disease-free, 9% died of recurrent breast cancer, and 13% died of other causes. Conclusions. These results suggest that surgical resection is beneficial in this group and should be considered, even for patients previously deemed ineligible for surgery.

  4. The importance of preoperative diagnosis of blister aneurysms.

    Russin, Jonathan J; Kramer, Daniel R; Thomas, Debi; Hasson, Denise; Liu, Charles Y; Amar, Arun P; Mack, William J; Giannotta, Steven L


    We describe a series of 14 surgical blister aneurysm (BA) patients and compare outcomes in those with known cerebral BA to those lacking preoperative BA diagnosis/recognition. BA are broad, fragile, pathologic dilatations of the intracranial arteries. They have a low prevalence but are associated with substantially higher surgical morbidity and mortality rates than saccular aneurysms. A confirmed, preoperative BA diagnosis can alter operative management and technique. We performed a retrospective review of prospectively collected data on aneurysm patients undergoing surgery at a major academic institution. All patients from 1990 to 2011 with a postoperative BA diagnosis were included. Chart reviews were performed to identify patients with preoperative BA diagnoses and collect descriptive data. We identified 14 patients, 12 of whom presented with subarachnoid hemorrhage. The age of the cohort (mean ± standard deviation: 41.8 ± 13.9 years) was lower than that generally reported for saccular aneurysm populations. Preoperatively diagnosed BA had an intraoperative rupture (IOR) rate of 28.6% (2/7) compared to a 57.1% (4/7) rate in the undiagnosed patients. The mortality rate in the preoperatively diagnosed cohort was 14.3% (1/7) while that of the undiagnosed group was 42.8% (3/7). BA remain a diagnostic and treatment challenge with morbidity and mortality rates exceeding those of saccular aneurysms. Preoperative BA diagnosis may decrease IOR and mortality rates and improve patient outcomes.

  6. Endovascular aneurysm repair: state-of-art imaging techniques for preoperative planning and surveillance

    Truijers, M; Resch, T; Van Den Berg, J C


    Endovascular aneurysm repair (EVAR) represents one of the greatest advances in vascular surgery over the past 50 years. In contrast to conventional aneurysm repair, EVAR requires accurate preoperative imaging and stringent postoperative surveillance. Duplex ultrasound (DUS), transesophageal...... echocardiography, intravascular ultrasound, computed tomography (CT) and magnetic resonance (MR), each provide useful information for patient selection, choice of endograft type and surveillance. Today most interventionists and surgeons will rely on CT or MR to assess aortic morphology, evaluate access artery...

    Background Several difficulties can arise from wide-neck cerebral aneurysms when treated with endovascular embolization. We aimed to investigate the effect of endovascular treatment of intracranial aneurysms using coil embolization plus an Enterprise stent.Methods Forty patients were treated with coil embolization plus an Enterprise stent between December 2008 and June 2010.Results The mortality of patients was 0. All stents were successfully implanted without any surgery-related complication.Conclusion The Enterprise stent has some advantages to be selected.

  8. Upper gastrointestinal obstruction secondary to aortoduodenal syndrome owing to a noninflammatory abdominal aortic aneurysm.

    Cahill, Kevin


    Aortoduodenal syndrome is a rare complication of an abdominal aortic aneurysm wherein the aneurysm sac obstructs the patient\\'s duodenum. It presents with the symptoms of an upper gastrointestinal tract obstruction and requires surgical intervention to relieve it. Previously, gastric bypass surgery was advocated, but now aortic replacement is the mainstay of treatment. We report a case of a 67-year-old woman whose aortoduodenal syndrome was successfully managed and review the literature on this topic.

    Dalainas, I; Nano, G; Ranucci, M; Bianchi, P; Stegher, S; Casana, R; Malacrida, G; Tealdi, D G


    The aim of the study was to report a 20-year single Institution experience, with the early and late outcomes of surgical treatment of inflammatory abdominal aortic aneurysms. In a 20-year period, 2 275 consecutive patients underwent elective surgical repair for non-rupture abdominal aortic aneurysm. Fifty-two patients (2.3%) were classified as inflammatory abdominal aortic aneurysms. Early and late outcomes were analyzed. One patient died in the perioperative period, giving a mortality rate of 1.92%. One patient died from a pseudoaneurysm rupture 7 months after operation. Three patients developed an aortic pseudoaneurysm in the follow-up period (mean 12.1 years, range 1-20 years) and underwent a redo operation. Overall surgical outcome of these patients, in terms of short-term and long-term is good. A high rate of pseudoaneurysm formation was observed.

    Petchara S


    Full Text Available Objective: To evaluate the postoperative outcome after using combined lumbar and sacral plexus block (CLSB, as a sole anesthetic method in hip fracture (HF surgery in highrisk geriatric patients. Materials and Methods: A single-center retrospective study was conducted, between 2010 and 2012, on 70 elderly HF patients with American Society of Anesthesiologists grading III-IV who underwent early surgical intervention with our CLSB protocol. Perioperative data, outcome, and complications were recorded. Results: Forty-eight patients (69% had ongoing anticoagulant medication. Postoperatively, all patients were hemodynamically stable and awake. None of them required general anesthesia conversion. Minor anesthetic-related complications were found in nine patients. One patient (1% died from sepsis due to pneumonia. Patients’ satisfactions were all rated as very good or excellent. Conclusion: CLSB is an interesting anesthetic option in HF surgery, especially in high surgical risk geriatric patients. This method offers an excellent clinical efficiency and high patients’ satisfaction without serious complications.

    Posniak, H V; Olson, M C; Demos, T C; Benjoya, R A; Marsan, R E


    Aneurysms of the thoracic aorta are most often the result of arteriosclerotic disease. Other causes include degeneration of the medial layer of the aortic wall, either idiopathically or due to genetic disorders such as Marfan syndrome; aortic dissection; trauma; syphilis and other bacterial infection; noninfective aortitis; and congenital anomaly. We review normal anatomy of the aorta and discuss our technique and interpretation of computed tomography (CT) in the evaluation of the thoracic aorta. We illustrate the CT appearance of different types of aortic aneurysms as well as discuss the use of CT for assessing complications of aneurysms, for postoperative follow-up, and in the differentiation of aortic aneurysm from a paraaortic mass.

  12. The 10-Year Local Recurrence and Partial Breast Radiotherapy for Early Breast Cancer Treated by Conservative Surgery

    Zhizhen Wang; Ruiying Li


    OBJECTIVE To study the local recurrence and the role of whole breast radiotherapy for early breast cancer treated by conservative surgery.METHODS From April 1990 to December 2000, 49 patients with early primary breast cancer were treated by conservative surgery in our hospital. The cases were comprised of Stage 0, 1; Stage Ⅰ, 31; and Stage Ⅱa,17. Forty cases underwent quadrantectomy plus axillary lymph node dissection, and the other 9 cases had lumpectomy alone. Irradiation, which was received by 39 patients, was administered by using low tangential half fields with 6 MV X-ray to decrease the pulmonary irradiative volume.The dose to the whole breast was 45 Gy/22~23f/4.5W, then a 15 Gy boost dose was delivered to the tumor bed by an electron beam. The other patients underwent an irradiated regional field according to postoperative pathology.RESULTS All patients were followed-up for 10 years or more. The 10year local recurrence rates, distant metastasis rates and survival rates were 6.1%, 4.1% and 98.0% respectively. All of the 3 patients who had a local recurrence had infiltrative carcinomas and negative lymph nodes.The 10-year local recurrence rate was higher (2.6% vs. 20.0%) with nonpostoperative whole breast radiotherapy, but the statistical difference was not marked because of the low number of cases. All of the recurrent lesions localized within 3 cm of the primary lesion.CONCLUSION Original recurrence of the tumor was the main type of local recurrence. Radiotherapy after conservative surgery is very essential.After conservative surgery it is feasible that irradiation can be delivered alone to the neighboring region of the tumor bed. Partial breast radiotherapy can substitute for whole breast radiotherapy.

    To study innate immune pathways in patients undergoing hepatopancreaticobiliary surgery to understand mechanisms leading to enhanced inflammatory responses and identifying biomarkers of adverse clinical consequences. Patients undergoing major abdominal surgery are at risk of life-threatening systemic inflammatory response syndrome (SIRS) and sepsis. Early identification of at-risk patients would allow tailored postoperative care and improve survival. Two separate cohorts of patients undergoing major hepatopancreaticobiliary surgery were studied (combined n = 69). Bloods were taken preoperatively, on day 1 and day 2 postoperatively. Peripheral blood mononuclear cells and serum were separated and immune phenotype and function assessed ex vivo. Early innate immune dysfunction was evident in 12 patients who subsequently developed SIRS (postoperative day 6) compared with 27 who did not, when no clinical evidence of SIRS was apparent (preoperatively or days 1 and 2). Serum interleukin (IL)-6 concentration and monocyte Toll-like receptor (TLR)/NF-κB/IL-6 functional pathways were significantly upregulated and overactive in patients who developed SIRS (P SIRS. Increased TLR4 and TLR5 gene expression in whole blood was demonstrated in a separate validation cohort of 30 patients undergoing similar surgery. Expression of TLR4/5 on monocytes, particularly intermediate CD14CD16 monocytes, on day 1 or 2 predicted SIRS with accuracy 0.89 to 1.0 (areas under receiver operator curves). These data demonstrate the mechanism for IL-6 overproduction in patients who develop postoperative SIRS and identify markers that predict patients at risk of SIRS 5 days before the onset of clinical signs.

  14. Unstable angina early after aortic valve replacement surgery in a female patient with normal coronary arteries preoperatively – a case report

    Schwarz Christian


    Full Text Available Abstract Background Angina pectoris early after aortic valve replacement surgery in patients with previously normal coronary arteries may be life threatening and has to be assessed immediately. Case report 12 weeks after aortic valve replacement surgery, a 60-year-old female patient was referred for evaluation of recent onset of severe chest pain on mild exertion and at rest. Coronary angiography showed severe stenosis nvolving the left coronary ostium and the left main stem. The patient was urgently referred for bypass surgery and had an uneventful postoperative recovery. Conclusion A high degree of suspicion is needed for early recognition and aggressive management of this rare but serious complication.

  15. Left atrial volume index as a predictor for persistent left ventricular dysfunction after aortic valve surgery in patients with chronic aortic regurgitation: the role of early postoperative echocardiography.

    Cho, In-Jeong; Chang, Hyuk-Jae; Hong, Geu-Ru; Heo, Ran; Sung, Ji Min; Lee, Sang-Eun; Chang, Byung-Chul; Shim, Chi Young; Ha, Jong-Won; Chung, Namsik


    This study aimed to explore whether echocardiographic measurements during the early postoperative period can predict persistent left ventricular systolic dysfunction (LVSD) after aortic valve surgery in patients with chronic aortic regurgitation (AR). We prospectively recruited 54 patients (59 ± 12 years) with isolated chronic severe AR who subsequently underwent aortic valve surgery. Standard transthoracic echocardiography was performed before the operation, during the early postoperative period (≤2 weeks), and then 1 year after the surgery. Twelve patients with preoperative LVSD demonstrated LVSD at early after the surgery. Of the 42 patients without LVSD at preoperative echocardiography, 15 patients (36%) developed early postoperative LVSD after surgical correction. All 27 patients without LVSD at early postoperative echocardiography maintained LV function at 1 year after surgery. In the other 27 patients with postoperative LVSD, 17 patients recovered from LVSD and 10 patients did not at 1 year after surgery. Multiple logistic analysis demonstrated that postoperative left atrial volume index (LAVI) was the only independent predictor for persistent LVSD at 1 year after surgery in patients with postoperative LVSD (OR 1.180, 95% CI, 1.003-1.390, P = 0.046). The optimal LAVI cutoff value (>34.9 mL/m(2) ) had a sensitivity of 80% and a specificity of 88% for the prediction of persistent LVSD. Prevalence of early postoperative LVSD was relatively high, even in the patients without LVSD at preoperative echocardiography. Postoperative LAVI could be useful to predict persistent LVSD after aortic valve surgery in patients with early postoperative LVSD. © 2014, Wiley Periodicals, Inc.

  16. Congenital cataract surgery during the early enlightenment period and the Stepkins oculists.

    Leffler, Christopher T; Schwartz, Stephen G; Davenport, Byrd


    From antiquity through the Renaissance, congenital blindness was generally regarded as incurable, as noted in both medical and lay publications. The earliest reference to congenital cataract surgery that we identified, reported in 1663, referred to an 18-year-old female treated by English oculist John Stepkins (d. 1652). An examination of the literature related to the Stepkins family reveals the presence of male and female oculists during that period, including his daughter, Lady Theodosia Ivy. Eye waters attributed to Stepkins contained tutty (an oxide of zinc), roses, sugar candy, and other ingredients. Interestingly, John Thomas Woolhouse, the author of the next identified report of congenital cataract surgery in 1706, stated that he was related to Stepkins. Woolhouse reported by 1721 that he had performed 36 congenital cataract surgeries, with the youngest patient being 18 months of age.

  17. Influence of yoga on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery

    Rao Raghavendra


    Full Text Available Context : Pre- and postoperative distress in breast cancer patients can cause complications and delay recovery from surgery. Objective : The aim of our study was to evaluate the effects of yoga intervention on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery. Methods : Ninety-eight recently diagnosed stage II and III breast cancer patients were recruited in a randomized controlled trial comparing the effects of a yoga program with supportive therapy and exercise rehabilitation on postoperative outcomes and wound healing following surgery. Subjects were assessed at the baseline prior to surgery and four weeks later. Sociodemographic, clinical and investigative notes were ascertained in the beginning of the study. Blood samples were collected for estimation of plasma cytokines-soluble Interleukin (IL-2 receptor (IL-2R, tumor necrosis factor (TNF-alpha and interferon (IFN-gamma. Postoperative outcomes such as the duration of hospital stay and drain retention, time of suture removal and postoperative complications were ascertained. We used independent samples t test and nonparametric Mann Whitney U tests to compare groups for postoperative outcomes and plasma cytokines. Regression analysis was done to determine predictors for postoperative outcomes. Results : Sixty-nine patients contributed data to the current analysis (yoga: n = 33, control: n = 36. The results suggest a significant decrease in the duration of hospital stay ( P = 0.003, days of drain retention ( P = 0.001 and days for suture removal ( P = 0.03 in the yoga group as compared to the controls. There was also a significant decrease in plasma TNF alpha levels following surgery in the yoga group ( P < 0.001, as compared to the controls. Regression analysis on postoperative outcomes showed that the yoga intervention affected the duration of drain retention and hospital stay as well as TNF alpha levels. Conclusion : The results suggest

    To report the case of a pediatric patient with intramedullary spinal aneurysm. A 9-year-old boy presented with low back pain and subsequent gait disturbance. He had no history of trauma. After admission, MRI revealed an intramedullary spinal cord mass lesion surrounded by hemorrhage at the cervical-thoracic junction. Initial treatment was started with intravenous methylprednisolone and bed rest. Neurological deficit disappeared under careful observation for a few months. Surgical intervention was applied for diagnosis and resection of the mass lesion to prevent recurrent hemorrhage. Intraoperative ultrasound sonography helped to diagnose the lesion as a spinal cord aneurysm, prior to midline myelotomy. Monitoring of transcranial muscle evoked potentials helped to avoid spinal cord damage during surgery. There has been no evidence of spinal aneurysm on MRI for 3 years after surgery and no neurological deterioration. To our knowledge, this is a first report of an intramedullary spinal cord aneurysm at the cervical-thoracic junction in a pediatric patient. Careful observation after initial symptoms followed by surgical intervention was favorable in this case.

  19. The Familial Intracranial Aneurysm (FIA study protocol

    Meissner Irene


    Full Text Available Abstract Background Subarachnoid hemorrhage (SAH due to ruptured intracranial aneurysms (IAs occurs in about 20,000 people per year in the U.S. annually and nearly half of the affected persons are dead within the first 30 days. Survivors of ruptured IAs are often left with substantial disability. Thus, primary prevention of aneurysm formation and rupture is of paramount importance. Prior studies indicate that genetic factors are important in the formation and rupture of IAs. The long-term goal of the Familial Intracranial Aneurysm (FIA Study is to identify genes that underlie the development and rupture of intracranial aneurysms (IA. Methods/Design The FIA Study includes 26 clinical centers which have extensive experience in the clinical management and imaging of intracerebral aneurysms. 475 families with affected sib pairs or with multiple affected relatives will be enrolled through retrospective and prospective screening of potential subjects with an IA. After giving informed consent, the proband or their spokesperson invites other family members to participate. Each participant is interviewed using a standardized questionnaire which covers medical history, social history and demographic information. In addition blood is drawn from each participant for DNA isolation and immortalization of lymphocytes. High- risk family members without a previously diagnosed IA undergo magnetic resonance angiography (MRA to identify asymptomatic unruptured aneurysms. A 10 cM genome screen will be performed to identify FIA susceptibility loci. Due to the significant mortality of affected individuals, novel approaches are employed to reconstruct the genotype of critical deceased individuals. These include the intensive recruitment of the spouse and children of deceased, affected individuals. Discussion A successful, adequately-powered genetic linkage study of IA is challenging given the very high, early mortality of ruptured IA. Design features in the FIA Study

  20. The comparative study of the outcomes of early and late oral feeding in intestinal anastomosis surgeries in children

    Omid Amanollahi


    Full Text Available Background: A leakage of intestinal anastomosis is typically regarded as a devastating post-operative complication. Traditionally its believed that long fasting after intestinal surgery protect anastomosis site and most surgeons applied this method. Post-operative long fasting has many physical and mental adverse effects, especially in children, but its benefit has not proven yet. This study aimed to compare the outcomes of early and late oral feeding in intestinal resection and anastomosis surgery in children. Patients and Methods: This randomized, double-blind controlled trial evaluated the outcome of early-feeding following in children aged 1 month to 12 years who underwent intestinal resection and anastomosis and compared the results with those who had late-feeding. The results were anlysed for fever, nausea and vomiting, abdominal distension, first passage of gas and stool were also evaluated hospital stay time, major post-operative complications such as anastomosis leakage, wound infection or dehiscence, intra-abdominal abscess between the two groups. Results: The mean time of first oral feeding in the early feeding group (study group was 2.5 ± 0.7 days but it was 5.3 ± 0.6 days in the late feeding group (control group. There was no mortality in both groups. There was no difference in major complications in both groups (anastomosis leakage. In the study group, first defecation time was shorter than the control group (3.7 days v. 4.4 days and they had less hospital stay also (5.2 days vs. 8.3 days and lower cost of hospitalization. Conclusion: Early oral feeding after intestinal resection and anastomosis in children is a safe method, it has many benefits and does not increase the major or minor post-operative complications (anastomosis leakage long time fasting is not necessary and has not any beneficial effect and early feeding increases satisfaction of the parents and children, and reduce hospital stay and costs.

  1. Limitations of early serum creatinine variations for the assessment of kidney injury in neonates and infants with cardiac surgery.

    Mirela Bojan

    Full Text Available BACKGROUND: Changes in kidney function, as assessed by early and even small variations in serum creatinine (ΔsCr, affect survival in adults following cardiac surgery but such associations have not been reported in infants. This raises the question of the adequate assessment of kidney function by early ΔsCr in infants undergoing cardiac surgery. METHODOLOGY: The ability of ΔsCr within 2 days of surgery to assess the severity of kidney injury, accounted for by the risk of 30-day mortality, was explored retrospectively in 1019 consecutive neonates and infants. Patients aged ≤ 10 days were analyzed separately because of the physiological improvement in glomerular filtration early after birth. The Kml algorithm, an implementation of k-means for longitudinal data, was used to describe creatinine kinetics, and the receiver operating characteristic and the reclassification methodology to assess discrimination and the predictive ability of the risk of death. RESULTS: Three clusters of ΔsCr were identified: in 50% of all patients creatinine decreased, in 41.4% it increased slightly, and in 8.6% it rose abruptly. Mortality rates were not significantly different between the first and second clusters, 1.6% [0.0-4.1] vs 5.9% [1.9-10.9], respectively, in patients aged ≤ 10 days, and 1.6% [0.5-3.0] vs 3.8% [1.9-6.0] in older ones. Mortality rates were significantly higher when creatinine rose abruptly, 30.3% [15.1-46.2] in patients aged ≤ 10 days, and 15.1% [5.9-25.5] in older ones. However, only 41.3% of all patients who died had an abrupt increase in creatinine. ΔsCr improved prediction in survivors, but not in patients who died, and did not improve discrimination over a clinical mortality model. CONCLUSIONS: The present results suggest that a postoperative decrease in creatinine represents the normal course in neonates and infants with cardiac surgery, and that early creatinine variations lack sensitivity for the assessment of the severity of

  2. Comparison of multi-modal early oral nutrition for the tolerance of oral nutrition with conventional care after major abdominal surgery: a prospective, randomized, single-blind trial.

    Early oral nutrition (EON) has been shown to improve recovery of gastrointestinal function, length of stay and mortality after abdominal surgery; however, early oral nutrition often fails during the first week after surgery. Here, a multi-modal early oral nutrition program is introduced to promote recovery of gastrointestinal function and tolerance of oral nutrition. Consecutive patients scheduled for abdominal surgery were randomized to the multimodal EON group or a group receiving conventional care. The primary endpoint was the time of first defecation. The secondary endpoints were outcomes and the cost-effectiveness ratio in treating infectious complications. The rate of infectious-free patients was regarded as the index of effectiveness. One hundred seven patients were randomly assigned to groups. Baseline characteristics were similar for both groups. In intention-to-treat analysis, the success rate of oral nutrition during the first week after surgery in the multimodal EON group was 44 (83.0%) versus 31 (57.4%) in the conventional care group (P = 0.004). Time to first defecation, time to flatus, recovery time of bowel sounds, and prolonged postoperative ileus were all less in the multimodal EON group (P multi-modal early oral nutrition group (P multi-modal early oral nutrition program was an effective way to improve tolerance of oral nutrition during the first week after surgery, decrease the length of stay and improve cost-effectiveness after abdominal surgery.

  3. Open Repair for Abdominal Aortic Aneurysm in a Young Boy with Tuberous Sclerosis and Review of the Literature.

    Dueppers, Philip; Duran, Mansur; Grabitz, Klaus; Schelzig, Hubert


    Abdominal aortic aneurysms (AAAs) are very rare in pediatric patients and can rarely be associated with tuberous sclerosis (TS). Open surgery is the first-line therapy. We report our experience added by a review on current literature. A 9-year-old boy with TS and history of 2 earlier open repairs for AAA presented to our department with a recurrent juxtarenal aortic aneurysm. We performed a polytetraflourethylene patch plasty. Postoperative course was uneventful. After 8 months, reconstruction was stable, and no recurrent aneurysm developed. Recurrent aneurysms may develop after open surgery for TS-associated AAA. However, open surgery is the recommended therapy but requires special techniques and experience in pediatric patients. Copyright © 2016 Elsevier Inc. All rights reserved.

  4. Early oral feeding after elective abdominal surgery--what are the issues?

    Bisgaard, Thue; Kehlet, Henrik


    procedures. It appears that several factors may promote postoperative oral feeding such as thoracic epidural analgesia, multimodal anti-emetic treatment, opioid-sparing analgesia, selective peripheral opioid antagonists, and enforced oral nutrition. Recent data from multimodal fast-track rehabilitation...... surgical programs in abdominal surgery provide a rational basis for future studies to investigate and facilitate enforced oral feeding after major abdominal procedures....

  5. Acute cholecystitis – early laparoskopic surgery versus antibiotic therapy and delayed elective cholecystectomy: ACDC-study

    Büchler Markus W


    Full Text Available Abstract Background Acute cholecystitis occurs frequently in the elderly and in patients with gall stones. Most cases of severe or recurrent cholecystitis eventually require surgery, usually laparoscopic cholecystectomy in the Western World. It is unclear whether an initial, conservative approach with antibiotic and symptomatic therapy followed by delayed elective surgery would result in better morbidity and outcome than immediate surgery. At present, treatment is generally determined by whether the patient first sees a surgeon or a gastroenterologist. We wish to investigate whether both approaches are equivalent. The primary endpoint is the morbidity until day 75 after inclusion into the study. Design A multicenter, prospective, randomized non-blinded study to compare treatment outcome, complications and 75-day morbidity in patients with acute cholecystitis randomized to laparoscopic cholecystectomy within 24 hours of symptom onset or antibiotic treatment with moxifloxacin and subsequent elective cholecystectomy. For consistency in both arms moxifloxacin, a fluorquinolone with broad spectrum of activity and high bile concentration is used as antibiotic. Duration: October 2006 – November 2008 Organisation/Responsibility The trial was planned and is being conducted and analysed by the Departments of Gastroenterology and General Surgery at the University Hospital of Heidelberg according to the ethical, regulatory and scientific principles governing clinical research as set out in the Declaration of Helsinki (1989 and the Good Clinical Practice guideline (GCP.

  6. Early assessment of nutritional status in patients scheduled for colorectal cancer surgery.

    Karlsson, Seija; Andersson, Liv; Berglund, Britta


    Nutritional support is important to optimize treatment outcomes in colorectal cancer surgery. Using retrospective review of patients' medical records, we sought to identify the kinds of nutritional problems patients with colorectal cancer reported on their first visit to the surgeon to support those at risk of malnutrition. After reviewing data from the Patient-Generated Subjective Global Assessment of Nutritional Status, patients had a supportive counseling meeting about nutrition with a nurse. Of the 153 patients, 65% were diagnosed with colon cancer and 35% with rectal cancer. Eighteen percent of those with colon cancer were overweight, and 12% were obese. Of those with rectal cancer, 10% were overweight, and 7% were obese. Weight loss was reported by 18% of the patients with colon cancer and by 12% of the patients with rectal cancer. To identify the patients who need nutritional support before colorectal cancer surgery, it is important to first identify the patients' nutritional status. When the focus is on surgery, it is possible that these problems are not mentioned if no questions are asked. Nutritional assessment at the outpatient department makes it possible to use the time lapse between examination and surgery to improve the nutritional status.

  7. Ruptured abdominal aortic aneurysm.

    Sachs, T; Schermerhorn, M


    Ruptured abdominal aortic aneurysm (AAA) continues to be one of the most lethal vascular pathologies we encounter. Its management demands prompt and efficient evaluation and repair. Open repair has traditionally been the mainstay of treatment. However, the introduction of endovascular techniques has altered the treatment algorithm for ruptured AAA in most major medical centers. We present recent literature and techniques for ruptured AAA and its surgical management.

  8. Diagnostic value of 64-slice spiral CT angiography in the diagnosis of multiple intracranial aneurysms: a report of 25 cases

    Hong-sheng WANG


    Full Text Available Objective  To evaluate the diagnostic value of 64-slice spiral CT angiography (CTA in multiple intracranial aneurysms (MIA. Methods  Twenty-five patients (9 males and 16 females, aged from 17 to 68 years with suspected MIA underwent 64-slice spiral CTA with slice thickness of 0.625mm. The data of all patients were reconstructed with multiplanar reconstruction (MPR, 3-dimensional shade surface display (3-SSD, volume rendering (VR and maximum intensity projection (MIP. The clinical diagnostic value was evaluated with the results of surgery or interventional embolization therapy. Results  A total of 61 aneurysms were detected by 64-slice spiral CTA in 25 patients, among them 17 patients were with 2 aneurysms, 6 patients with 3 aneurysms, 1 patient with 4 aneurysms and 1 patient with 5 aneurysms. The 64-slice spiral CTA could not only clearly demonstrate MIA, but also the size, neck, axis point and parent artery of each aneurysm, and the spatial relationship between aneurysm and the adjacent vessels and bone structures. Twenty-one patients underwent microsurgery and four underwent embolization, the location, size and shape of aneurysm and its spatial relationship with adjacent structures were in accordance with the findings of 64-slice spiral CTA. Conclusion  The 64-slice spiral CTA could be used as the first choice in the diagnosis of MIA for its high accuracy, and may be an important adjunct to digital subtraction angiography (DSA in MIA treatment.

  9. [Coil embolization for incidental aneurysms in patients with chronic renal failure: midterm clinical results of two cases].

    Nakashima, T; Katou, T; Murakawa, T; Yamakawa, H; Yoshimura, S; Kaku, Y; Sakai, N


    In spite of recent advances in perioperative management, the risk of neurosurgical intervention for patients with chronic renal failure is still considered too high. In this study, coil embolization for incidental aneurysms in such patients is demonstrated in reference to midterm results. A 42-year-old woman with a history of hemodialisis for 7 years presented with subcortical hemorrhage in her right frontal lobe. The magnetic resonance angiography (MRA) demonstrated a distal anterior cerebral artery aneurysm, but it was considered to be unrelated to the hemorrhage. Two and a half months after the hemorrhage the aneurysm was embolized with interlocking detachable coils. Thirty months after embolization, the angiogram revealed the coil compaction and the recanalization of the aneurysm neck. However, 54 months after embolization, the figure of the embolized aneurysm and neck remnant was the same as the previous findings. A 69-year-old woman with a history of hemodialisis for 5 years suddenly experienced left hemiparesis. Computed tomography revealed cerebral infarction in the right frontoparietal white matter. In addition, a left middle cerebral artery aneurysm was unexpectedly found on the MRA. Five months after the onset of the attack, the aneurysm was embolized with a Guglielmi detachable coli. An angiogram obtained 24 months after the embolization showed the aneurysm to be almost completely obliterated. In considering the therapeutic risks and benefits for incidental aneurysms of patients with chronic renal failure, intra-vascular surgery could be recommended as a less invasive treatment.

    Aortic aneurysm disease is a complex condition that requires a multidisciplinary approach in management. The innovation and collaboration among vascular surgery, cardiothoracic surgery, interventional radiology, and other related specialties is essential for progress in the management of aortic aneurysms. The Fifth Liverpool Aortic Surgery Symposium that was held in May 2013 aimed at bringing national and international experts from across the United Kingdom and the globe to deliver their thoughts, applications, and advances in aortic and vascular surgery. In this report, we present a selected short synopsis of the key topics presented at this symposium.

    Rettig, Thijs C D; Verwijmeren, Lisa; Dijkstra, Ineke M; Boerma, Djamila; van de Garde, Ewoudt M W; Noordzij, Peter G


    To assess the association of systemic inflammation and outcome after major abdominal surgery. Major abdominal surgery carries a high postoperative morbidity and mortality rate. Studies suggest that inflammation is associated with unfavorable outcome. Levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α and the systemic inflammatory response syndrome (SIRS) were assessed in 137 patients undergoing major abdominal surgery. Blood samples were drawn on days 0, 1, 3, and 7, and SIRS was scored during 48 hours after surgery. Primary outcome was a composite of mortality, pneumonia, sepsis, anastomotic dehiscence, wound infection, noncardiac respiratory failure, atrial fibrillation, congestive heart failure, myocardial infarction, and reoperation within 30 days of surgery. An IL-6 level more than 432 pg/mL on day 1 was associated with an increased risk of complications (adjusted odds ratio: 3.3; 95% confidence interval [CI]: 1.3-8.5) and a longer median length of hospital stay (7 vs 12 days, P < 0.001). As a single test, an IL-6 cut-off level of 432 pg/mL on day 1 yielded a specificity of 70% and a sensitivity of 64% for the prediction of complications (area under the curve: 0.67; 95% CI: 0.56-0.77). Levels of CRP started to discriminate from day 3 onward with a specificity of 87% and a sensitivity of 58% for a cut-off level of 203 mg/L (AUC: 0.73; 95% CI: 0.63-0.83). A high IL-6 level on day 1 is associated with postoperative complications. Levels of IL-6 help distinguish between patients at low and high risk for complications before changes in levels of CRP.

    The incidence of tertiary syphilis has declined in recent years owing to the early recognition of the disease and use of antibiotics. As a result, syphilitic aortic aneurysms are rarely encountered nowadays. We report the case of a 65 years old man, who was admitted to our hospital in June 2004 for dyspnea, cough and chest discomfort. On physical examination, blood pressure was 130/80 mmHg with no significant laterality, pulse rate was 70 per minute and there was a decrease of breath sounds over the right lung. Laboratory findings revealed a slight elevation of the erythrocyte sedimentation rate. Serological studies for syphilis showed a positive venereal disease laboratory test (VDRL) at 1/32 and a positive Treponema pallidum hemagglutination test (TPHA) at 1/2560. The chest radiography showed a right para cardiac opacity measuring 16 x 12 cm. Fiber optic bronchoscopy showed an extrinsic compression of the right upper lobar bronchus. Gadolinium-enhanced magnetic resonance angiography and 16 multidetector-row spiral computed aortography showed a huge partially thrombosed saccular aneurysm of the ascending aorta measuring 132 mm in diameter. The circulating lumen measured 53 mm in its largest diameter. This aneurysm involved the innominate artery. There was no other arterial involvement. The patient was given a three week course of intravenous penicillin followed by a successful surgical procedure in September 2004 with ascending aortic replacement and innominate artery reimplantation. This case illustrates well a formerly common, but now extremely rare disease.

    The development of new diagnostic technologies for cerebrovascular diseases requires an understanding of the mechanism behind the growth and rupture of cerebral aneurysms. To provide a comprehensive diagnosis and prognosis of this disease, it is desirable to evaluate wall shear stress, pressure, deformation and strain in the aneurysm region, based on information provided by medical imaging technologies. In this research, we propose a new cyber-physical system composed of in vitro dynamic strain experimental measurements and computational fluid dynamics (CFD) simulation for the diagnosis of cerebral aneurysms. A CFD simulation and a scaled-up membranous silicone model of a cerebral aneurysm were completed, based on patient-specific data recorded in August 2008. In vitro blood flow simulation was realized with the use of a specialized pump. A vision system was also developed to measure the strain at different regions on the model by way of pulsating blood flow circulating inside the model. Experimental results show that distance and area strain maxima were larger near the aneurysm neck (0.042 and 0.052), followed by the aneurysm dome (0.023 and 0.04) and finally the main blood vessel section (0.01 and 0.014). These results were complemented by a CFD simulation for the addition of wall shear stress, oscillatory shear index and aneurysm formation index. Diagnosis results using imaging obtained in August 2008 are consistent with the monitored aneurysm growth in 2011. The presented study demonstrates a new experimental platform for measuring dynamic strain within cerebral aneurysms. This platform is also complemented by a CFD simulation for advanced diagnosis and prediction of the growth tendency of an aneurysm in endovascular surgery. Copyright © 2013 John Wiley & Sons, Ltd.

    Manuel, Valdano; Sousa-Uva, Miguel; Miguel, Gade; Magalhães, Manuel Pedro; Pedro, Albino; Júnior, António Pedro Filipe; Morais, Humberto


    We report a surgical series of submitral aneurysm in children. Between March 2011 and December 2015, eight consecutive patients less than 18 years old with submitral aneurysm underwent surgical correction. Six patients were female, the mean age was 7 ± 3.8 years old, and mean weight was 21.4 kg. Six patients were in NYHA functional class III or IV. Six patients underwent repair via a transatrial approach, another with a transatrial combined with transaneurysmal approach, and another with a transventricular approach. There were no in-hospital deaths but one 30-day mortality. One patient required reoperation. Two patients required mitral valve replacement. At discharge, one patient had severe and another had moderate mitral regurgitation. The mean follow-up time was 26.4 months and five patients were alive. No reintervention was required. Submitral aneurysm is not restricted to adults. Heart failure is the commonest clinical presentation in the pediatric age. The transatrial approach is feasible, safe, and associated with good short-term results. The mitral valve can be preserved in the majority of cases. © 2016 Wiley Periodicals, Inc.

  15. Is population screening for abdominal aortic aneurysm cost-effective?

    Jensen Lotte


    Full Text Available Abstract Background Ruptured abdominal aortic aneurysm (AAA is responsible for 1–2% of all male deaths over the age of 65 years. Early detection of AAA and elective surgery can reduce the mortality risk associated with AAA. However, many patients will not be diagnosed with AAA and have therefore an increased death risk due to the untreated AAA. It has been suggested that population screening for AAA in elderly males is effective and cost-effective. The purpose of this study was to perform a systematic review of published cost-effectiveness analyses of screening elderly men for AAA. Methods We performed a systematic search for economic evaluations in NHSEED, EconLit, Medline, Cochrane, Embase, Cinahl and two Scandinavian HTA data bases (DACEHTA and SBU. All identified studies were read in full and each study was systematically assessed according to international guidelines for critical assessment of economic evaluations in health care. Results The search identified 16 cost-effectiveness studies. Most studies considered only short term cost consequences. The studies seemed to employ a number of "optimistic" assumptions in favour of AAA screening, and included only few sensitivity analyses that assessed less optimistic assumptions. Conclusion Further analyses of cost-effectiveness of AAA screening are recommended.

  16. The effect of patient-selected music on early postoperative pain, anxiety, and hemodynamic profile in cesarean section surgery.

    Ebneshahidi, Amin; Mohseni, Masood


    After cesarean section surgery, routine pharmacologic methods of analgesia--opioids and benzodiazepines--may impair the immediate close contact of mother and neonate for their sedative and emetic effects. The aim of this study was to explore the effect of patient-selected music on postoperative pain, anxiety, opioid requirement, and hemodynamic profile. A total of 80 patients, American Society of Anesthesiologists (ASA) physical status I-II, scheduled to undergo general anesthesia and elective cesarean section surgery were enrolled. Patients were randomly allocated to receive 30 minutes of music or silence via headphones postoperatively. Pain and anxiety were measured with a visual analogue scale. Total postoperative morphine requirement as well as blood pressure and heart rate were recorded after the intervention period. Pain score and postoperative cumulative opioid consumption were significantly lower among patients in the music group (p 0.05). Postoperative use of patient-selected music in cesarean section surgery would alleviate the pain and reduce the need for other analgesics, thus improving the recovery and early contact of mothers with their children.

    Ziadi Jaleleddine


    Full Text Available A 12-year-old boy with coarctation of aorta developed infective endarteritis and mycotic aneurysm at the site distal to coarctation. The computed tomography angiogram was very helpful in the diagnosis. Medical management and early surgical intervention was curative. Infective endarteritis in coarctation may be underdiagnosed.

  19. Genetic and Epigenetic Regulation of Aortic Aneurysms

    Kim, Ha Won


    Aneurysms are characterized by structural deterioration of the vascular wall leading to progressive dilatation and, potentially, rupture of the aorta. While aortic aneurysms often remain clinically silent, the morbidity and mortality associated with aneurysm expansion and rupture are considerable. Over 13,000 deaths annually in the United States are attributable to aortic aneurysm rupture with less than 1 in 3 persons with aortic aneurysm rupture surviving to surgical intervention. Environmental and epidemiologic risk factors including smoking, male gender, hypertension, older age, dyslipidemia, atherosclerosis, and family history are highly associated with abdominal aortic aneurysms, while heritable genetic mutations are commonly associated with aneurysms of the thoracic aorta. Similar to other forms of cardiovascular disease, family history, genetic variation, and heritable mutations modify the risk of aortic aneurysm formation and provide mechanistic insight into the pathogenesis of human aortic aneurysms. This review will examine the relationship between heritable genetic and epigenetic influences on thoracic and abdominal aortic aneurysm formation and rupture. PMID:28116311

  1. [The treatment of abdominal aortic aneurysms by use of endovascular prosthesis and classic vascular prosthesis].

    Pupka, Artur; Szyber, Przemysław P; Janczak, Dariusz; Pawłowski, Stanisław; Szyber, Piotr


    The abdominal aortic aneurysm is a dilatation of infrarenal part of aorta. Its ethiology is still unknown. An infection and congenital disorders of conjunctive tissue are regarded as the main risc factors. Other factors could be a perimural thrombus and elastin and colagen degradation. It's not proved that atheromatosis is a risc factor. The disease concerns mainly the old males. Not treated aneurysm grows until rupture. The aneurysms are usually asympthomatic. Majority of them are found incidentally. Ultrasonography and computed tomography are used to extended diagnosis. The open surgery or endovascular surgery are only possible ways of treatment. The aneurysm with diameter over 55 milimeters, sympthomatic or rupted is an indication for surgery. The aim of the open surgery is implantation of the vascular prosthesis into retroperitoneal space. Endovascular method consist in placement of stent-graft in the lumen of aneurysm through small incision in a peripherial vessel. Stent-graft consists of metal chassis covered by classic vascular prosthesis. This method still requires the long-term assessment.

  2. Endovascular treatment of blister aneurysms.

    Peitz, Geoffrey W; Sy, Christopher A; Grandhi, Ramesh


    Blister aneurysms are rare cerebrovascular lesions for which the treatment methods are reviewed here, with a focus on endovascular options. The reported pathogenesis of blister aneurysms varies, and hemodynamic stress, arterial dissection, and arteriosclerotic ulceration have all been described. There is consensus on the excessive fragility of blister aneurysms and their parent vessels, which makes clipping technically difficult. Open surgical treatment is associated with high rates of complications, morbidity, and mortality; endovascular treatment is a promising alternative. Among endovascular treatment options, deconstructive treatment has been associated with higher morbidity compared with reconstructive methods such as direct embolization, stent- or balloon-assisted direct embolization, stent monotherapy, and flow diversion. Flow diversion has been associated with higher technical success rates and similar clinical outcomes compared with non-flow diverting treatment methods. However, delayed aneurysm occlusion and the need for antiplatelet therapy are potential drawbacks to flow diversion that must be considered when choosing among treatment methods for blister aneurysms.

  3. True aneurysm of brachial artery.

    Hudorović, Narcis; Lovričević, Ivo; Franjić, Dario Bjorn; Brkić, Petar; Tomas, Davor


    True upper extremity peripheral artery aneurysms are a rarely encountered arterial disorder. Following computer-tomography angiographic (CT-a) imaging examination, true saccular aneurysm, originating from the left brachial artery was diagnosed in the 77-year-old female without history of trauma. The aneurysm was resected by surgical intervention, and primary repair of the brachial artery was performed by interposition of a part of great saphenous vein harvested from the left groin and creation of two end-to-end anastomoses between interposition graft and previously resected part of brachial artery. No complication was observed during the follow-up. Surgical intervention for upper extremity aneurysms should be initiated without delay. Factors combined with minimal morbidity associated with repair suggest that surgical repair should be performed routinely for true upper extremity arterial aneurysms.

  4. Tobacco smoking and aortic aneurysm

    Sode, Birgitte F; Nordestgaard, Børge G; Grønbæk, Morten


    BACKGROUND: We determined the predictive power of tobacco smoking on aortic aneurysm as opposed to other risk factors in the general population. METHODS: We recorded tobacco smoking and other risk factors at baseline, and assessed hospitalization and death from aortic aneurysm in 15,072 individuals...... General Population Study, respectively. According to the magnitude of the hazard ratios, tobacco consumption was the most important risk factor for hospitalization and death from aortic aneurysm, followed by male sex and hypertension in both cohorts. The population attributable risk of aortic aneurysm...... outcomes due to tobacco consumption was 64% and 47% in the Copenhagen City Heart Study and Copenhagen General Population Study, respectively, and ranked highest among population attributable risks of aortic aneurysm in both cohorts. The absolute 10-year risk for hospitalization or death from aortic...

  5. Clinical assessment of peripheral perfusion to predict postoperative complications after major abdominal surgery early: a prospective observational study in adults


    Introduction Altered peripheral perfusion is strongly associated with poor outcome in critically ill patients. We wanted to determine whether repeated assessments of peripheral perfusion during the days following surgery could help to early identify patients that are more likely to develop postoperative complications. Methods Haemodynamic measurements and peripheral perfusion parameters were collected one day prior to surgery, directly after surgery (D0) and on the first (D1), second (D2) and third (D3) postoperative days. Peripheral perfusion assessment consisted of capillary refill time (CRT), peripheral perfusion index (PPI) and forearm-to-fingertip skin temperature gradient (Tskin-diff). Generalized linear mixed models were used to predict severe complications within ten days after surgery based on Clavien-Dindo classification. Results We prospectively followed 137 consecutive patients, from among whom 111 were included in the analysis. Severe complications were observed in 19 patients (17.0%). Postoperatively, peripheral perfusion parameters were significantly altered in patients who subsequently developed severe complications compared to those who did not, and these parameters persisted over time. CRT was altered at D0, and PPI and Tskin-diff were altered on D1 and D2, respectively. Among the different peripheral perfusion parameters, the diagnostic accuracy in predicting severe postoperative complications was highest for CRT on D2 (area under the receiver operating characteristic curve = 0.91 (95% confidence interval (CI) = 0.83 to 0.92)) with a sensitivity of 0.79 (95% CI = 0.54 to 0.94) and a specificity of 0.93 (95% CI = 0.86 to 0.97). Generalized mixed-model analysis demonstrated that abnormal peripheral perfusion on D2 and D3 was an independent predictor of severe postoperative complications (D2 odds ratio (OR) = 8.4, 95% CI = 2.7 to 25.9; D2 OR = 6.4, 95% CI = 2.1 to 19.6). Conclusions In a group of patients assessed following major abdominal surgery

    Objective: Early laryngeal cancer is usually treated with either transoral laser surgery or radiation therapy. The quality of voice achieved with these treatments has not been compared in a randomized trial. Methods and Materials: Male patients with carcinoma limited to 1 mobile vocal cord (T1aN0M0) were randomly assigned to receive either laser surgery (n=32) or external beam radiation therapy (n=28). Surgery consisted of tumor excision with a CO{sub 2} laser with the patient under general anaesthesia. External beam radiation therapy to the larynx was delivered to a cumulative dose of 66 Gy in 2-Gy daily fractions over 6.5 weeks. Voice quality was assessed at baseline and 6 and 24 months after treatment. The main outcome measures were expert-rated voice quality on a grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, videolaryngostroboscopic findings, and the patients' self-rated voice quality and its impact on activities of daily living. Results: Overall voice quality between the groups was rated similar, but voice was more breathy and the glottal gap was wider in patients treated with laser surgery than in those who received radiation therapy. Patients treated with radiation therapy reported less hoarseness-related inconvenience in daily living 2 years after treatment. Three patients in each group had local cancer recurrence within 2 years from randomization. Conclusions: Radiation therapy may be the treatment of choice for patients whose requirements for voice quality are demanding. Overall voice quality was similar in both treatment groups, however, indicating a need for careful consideration of patient-related factors in the choice of a treatment option.

  7. Early mortality after neonatal surgery: analysis of risk factors in an optimized health care system for the surgical newborn

    Dora Catré


    Full Text Available OBJECTIVE: Anesthetic and operative interventions in neonates remain hazardous procedures, given the vulnerability of the patients in this pediatric population. The aim was to determine the preoperative and intraoperative factors associated with 30-day post-operative mortality and describe mortality outcomes following neonatal surgery under general anesthesia in our center. METHODS: Infants less than 28 days of age who underwent general anesthesia for surgery during an 11-year period (2000 - 2010 in our tertiary care pediatric center were retrospectively identified using the pediatric intensive care unit database. Multiple logistic regression was used to identify independent preoperative and intraoperative factors associated with 30-day post-operative mortality. RESULTS: Of the 437 infants in the study (median gestational age at birth 37 weeks, median birth weight 2,760 grams, 28 (6.4% patients died before hospital discharge. Of these, 22 patients died within the first post-operative month. Logistic regression analysis showed increased odds of 30-day post-operative mortality among patients who presented American Society of Anesthesiologists physical status (ASA score 3 or above (odds ratio 19.268; 95%CI 2.523 - 147.132 and surgery for necrotizing enterocolitis/gastrointestinal perforation (OR 5.291; 95%CI 1.962 - 14.266, compared to those who did not. CONCLUSION: The overall in-hospital mortality of 6.4% is within the prevalence reported for developed countries. Establishing ASA score 3 or above and necrotizing enterocolitis/gastrointestinal perforation as independent risk factors for early mortality in neonatal surgery may help clinicians to more adequately manage this high risk population.

  8. Early assessment of feasibility and technical specificities of transoral robotic surgery using the da Vinci Xi.

    Gorphe, Philippe; Von Tan, Jean; El Bedoui, Sophie; Hartl, Dana M; Auperin, Anne; Qassemyar, Quentin; Moya-Plana, Antoine; Janot, François; Julieron, Morbize; Temam, Stephane


    The latest generation Da Vinci(®) Xi™ Surgical System Robot released has not been evaluated to date in transoral surgery for head and neck cancers. We report here the 1-year results of a non-randomized phase II multicentric prospective trial aimed at assessing its feasibility and technical specificities. Our primary objective was to evaluate the feasibility of transoral robotic surgery using the da Vinci(®) Xi™ Surgical System Robot. The secondary objective was to assess peroperative outcomes. Twenty-seven patients, mean age 62.7 years, were included between May 2015 and June 2016 with tumors affecting the following sites: oropharynx (n = 21), larynx (n = 4), hypopharynx (n = 1), parapharyngeal space (n = 1). Eighteen patients were included for primary treatment, three for a local recurrence, and six for cancer in a previously irradiated field. Three were reconstructed with a FAMM flap and 6 with a free ALT flap. The mean docking time was 12 min. "Chopsticking" of surgical instruments was very rare. During hospitalization following surgery, 3 patients experienced significant bleeding between day 8 and 9 that required surgical transoral hemostasis (n = 1) or endovascular embolization (n = 2). Transoral robotic surgery using the da Vinci(®) Xi™ Surgical System Robot proved feasible with technological improvements compared to previous generation surgical system robots and with a similar postoperative course. Further technological progress is expected to be of significant benefit to the patients.

    Buzzonetti, Luca; Capozzi, Paolo; Petrocelli, Gianni; Valente, Paola; Petroni, Sergio; Menabuoni, Luca; Rossi, Francesca; Pini, Roberto


    To evaluate the efficacy of diode laser welding to close corneal wounds in penetrating keratoplasty (PKP) and cataract surgery in pediatric patients. Ophthalmology Department, Bambino Gesù Children's Hospital, Rome, Italy. Prospective observational study. Patients had surgery for congenital cataract (Group 1) or femtosecond laser-assisted PKP (Group 2). The surgery was followed by corneal wound closure using diode laser welding of the stroma. In Group 1, no standard suturing was used. In Group 2, the donor button was sutured onto the recipient using 8 single nylon sutures or a 10-0 nylon running suture (12 passages). Laser welding was then used as an adjunct to the traditional suturing procedure. Group 1 comprised 7 eyes (7 patients; mean age 8.1 years ± 5.3 [SD], range 1 to 15 years) and Group 2, 5 eyes (5 patients; mean age 10.6 ± 3.3 years, range 6 to 15 years). The adhesion of the laser-welded tissues was perfect; there were no collateral effects, and restoration of the treated tissues was optimum. Seidel testing showed no wound leakage during the follow-up. Postoperative astigmatism did not change significantly from the first day after cataract surgery and shifted moderately 3 months after PKP. Laser welding of corneal tissue appeared to be safe and effective in children for whom a sutureless surgical procedure is important to reduce the use of anesthesia for suture management, prevent endophthalmitis, and improve the antiamblyopic effect.

  11. Protocol for a multicentre randomised feasibility trial evaluating early Surgery Alone In LOw Rectal cancer (SAILOR)

    Thorne, Kymberley; Hutchings, Hayley; Islam, Saiful; Holland, Gail; Hatcher, Olivia; Gwynne, Sarah; Jenkins, Ian; Coyne, Peter; Duff, Michael; Feldman, Melanie; Winter, Des C; Gollins, Simon; Quirke, Phil; West, Nick; Brown, Gina; Fitzsimmons, Deborah; Brown, Alan; Beynon, John


    Introduction There are 11 500 rectal cancers diagnosed annually in the UK. Although surgery remains the primary treatment, there is evidence that preoperative radiotherapy (RT) improves local recurrence rates. High-quality surgery in rectal cancer is equally important in minimising local recurrence. Advances in MRI-guided prediction of resection margin status and improvements in abdominoperineal excision of the rectum (APER) technique supports a reassessment of the contribution of preoperative RT. A more selective approach to RT may be appropriate given the associated toxicity. Methods and analysis This trial will explore the feasibility of a definitive trial evaluating the omission of RT in resectable low rectal cancer requiring APER. It will test the feasibility of randomising patients to (1) standard care (neoadjuvant long course RT±chemotherapy and APER, or (2) APER surgery alone for cT2/T3ab N0/1 low rectal cancer with clear predicted resection margins on MRI. RT schedule will be 45 Gy over 5 weeks as current standard, with restaging and surgery after 8–12 weeks. Recruitment will be for 24 months with a minimum 12-month follow-up. Objectives Objectives include testing the ability to recruit, consent and retain patients, to quantify the number of patients eligible for a defin
