    Full Text Available We describe an incident of development of acute pulmonary edema after the device closure of a secundum atrial septal defect in a 52-year-old lady, which was treated with inotropes, diuretics and artificial ventilation. Possibility of acute left ventricular dysfunction should be considered after the defect closure in the middle-aged patients as the left ventricular compliance may be reduced due to increased elastic stiffness and diastolic dysfunction. Baseline left atrial pressure may be > 10 mmHg in these patients. Associated risk factors for the left ventricular dysfunction are a large Qp:Qs ratio, systemic hypertension, severe pulmonary hypertension and paroxysmal atrial fibrillation.

    Full Text Available Echocardiography provides a useful tool in the diagnosis of many congenital heart diseases, including atrial septal defects, and aids in further delineating treatment options. Although two-dimensional echocardiography has been the standard of care in this regard, technological advancements have made three-dimensional echocardiography possible, and the images obtained in this new imaging modality are able to accurately portray the morphology, location, dimensions, and dynamic changes of defects and many other heart structures during the cardiac cycle.

  10. Initial experience in Brazil with the Helex septal occluder for percutaneous occlusion of atrial septal defects

    2003-01-01

    Full Text Available OBJECTIVE: To evaluate the initial clinical experience with the Helex septal occluder for percutaneous closure of atrial septal defects. METHODS: Ten patients underwent the procedure, 7 patients with ostium secundum atrial septal defects (ASD with hemodynamic repercussions and 3 patients with pervious foramen ovale (PFO and a history of stroke. Mean age was 33.8 years and mean weight was 55.4 kg. Mean diameter by transesophageal echocardiography and mean stretched ASD diameter were 11.33 ± 3.3mm, and 15.2 ± 3.8mm, respectively. The Qp/Qs ratio was 1.9 ± 0.3 in patients with ASD. RESULTS: Eleven occluders were placed because a patient with 2 holes needed 2 devices. It was necessary to retrieve and replace 4 devices in 3 patients. We observed immediate residual shunt (< 2mm in 4 patients with ASD, and in those with patent foramen ovale total occlusion of the defect occurred. No complications were noted, and all patients were discharged on the following day. After 1 month, 2 patients with ASD experienced trivial residual shunts (1mm. In 1 patient, we observed mild prolapse in the proximal disk in the right atrium, without consequences. CONCLUSION: The Helex septal occluder was safe and effective for occluding small to moderate atrial septal defects. Because the implantation technique is demanding, it requires specific training of the operator. Even so, small technical failures may occur in the beginning of the learning curve, but they do not involve patient safety.

    Objective To evaluate the safety and efficacy of the Amplatzer septal occluder for transcatheter closure in patients with secundum atrial septal defect (ASD Ⅱ). Methods Patients with clinically confirmed ASD Ⅱ were recommended for transcatheter closure of ASD Ⅱ. Results 30 ASD Ⅱ patients (20 females) underwent transcatheter closure at a median age of 18.4 years (5-55 years). Both the stretched diameters of ASDs and the sizes of the devices were from 18 to 34?mm (25±7?mm). The successful placement rate was 100%. The rest shunt documented by color Doppler, was immediately after implantation in 40% of patients, in 9.9% after 24 hours, and in 3.3% trace at 3 months. No serious complications were observed. There was improvement in symptoms and in cardiac size. Septal motion abnormalities normalized in all patients after 3 months follow-up. Conclusion The Amplatzer septal occluder is a safe and effective device for transcatheter closure of ASD Ⅱ. Long-term follow-up is still required before widespread clinical use can be recommended.

  13. Dysphagia Lusoria with atrial septal defect: Simultaneous repair through midline

    International Nuclear Information System (INIS)

    An aberrant right subclavian artery from the descending aorta is almost always reported as an isolated anomaly. We present the case of a four-year-old child with an anomalous origin of the right subclavian artery from the descending aorta, associated with an ostium secundum atrial septal defect. The patient underwent simultaneous repair of both the anomalies through median sternotomy, with implantation of the subclavian artery into the right common carotid artery. We believe that median sternotomy is the optimal surgical approach for the management of these lesions. Other operative approaches are also discussed

    Mid-line sternotomy is the routine approach for surgical repair of congenital heart diseases. However, its noticeable scar is a constant reminder of having undergone heart surgery. Several alternative approaches have been developed for simple cardiac conditions to hide the scar. Our series, consisting of 26 patients with axillary closure of atrial septal defect, is presented. The median age was 5.45 years (range 3-13), and median weight was 19.84 Kg. (range 13-37). The defect was closed directly in 13 cases, and with an autologous pericardial patch in the other 13. The number of surgical steps and time taken were the same as in median sternotomy. Functional recovery, intensive care unit stay, and hospital discharge were also standard. The cosmetic result, assessed both by patients and relatives, was excellent. PMID:23462094

    Sinus node (SN) and atrioventricular node (AVN) function were evaluated in 49 patients with secundum type atrial septal defect (ASD). Automaticity and conduction system function were assessed by intracardiac recording of the AH and HV intervals at rest, corrected SN recovery time, sinoatrial conduction time, AVN refractory period and the ability of the AVN to conduct rapidly paced atrial beats to the ventricles. Electrophysiologic abnormalities were found in 41% of the 34 patients who were studied before surgery. However, no preoperative abnormalities were present in children younger than 2.5 years. If only children older than 2.5 years were analyzed, the incidence of conduction abnormalities was similar for the patients studied before operation (62%) and those studied after operation (71%). The size and ejection fractions of the right and left ventricles, the magnitude of shunt flow and the size of the ASD did not differ between the patients with and those without electrophysiologic abnormalities. AVN dysfunction was present in 40% of the patients who were studied after surgical repair. While this frequency was more than twice the preoperative incidence of AVN dysfunction, it was not statistically significant. The data suggest that patient age is the major factor that influences the presence of conduction system dysfunction in patients with ASD.

    Bacterial endocarditis following atrial septal defect closure using Amplatzer device in a child is extremely rare. We report a 10-year-old girl who developed late bacterial endocarditis, 6 years after placement of an Amplatzer atrial septal occluder device. Successful explantation of the device and repair of the resultant septal defect was carried out using a homograft patch. The rare occurrence of this entity prompted us to highlight the importance of a closed long-term follow up, review the management and explore preventive strategies for similar patients who have multiple co-morbidities and a cardiac device. A high index of suspicion is warranted particularly in pediatric patients.

    2016-08-01

    Because of advances in cardiac structural interventional procedures, imaging techniques are playing an increasingly important role. Imaging studies show sufficient anatomic detail of the heart structure to achieve an excellent outcome in interventional procedures. Up to 98% of atrial septal defects at the ostium secundum can be closed successfully with a percutaneous procedure. Candidates for this type of procedure can be identified through a systematic assessment of atrial septum anatomy, locating and measuring the size and shape of all defects, their rims, and the degree and direction of shunting. Three dimensional echocardiography has significantly improved anatomic assessments and the end result itself. In the future, when combined with other imaging techniques such as cardiac computed tomography and fluoroscopy, 3-dimensional echocardiography will be particularly useful for procedure guidance. Percutaneous closure of the left atrial appendage offers an alternative for treating patients with atrial fibrillation and contraindication for oral anticoagulants. In the future, the clinical focus may well turn to stroke prevention in selected patients. Percutaneous closure is effective and safe; device implantation is successful in 94% to 99% of procedures. However, the procedure requires an experienced cardiac structural interventional team. At present, 3-dimensional echocardiography is the most appropriate imaging technique to assess anatomy suitability, select device type and size, guide the procedure alongside fluoroscopy, and to follow-up the patient afterwards.

    Atrial septal defect (ASD) is second common congenital heart disease that often leads to adult period. Intracardiac or transesophageal echocardiography (TEE) is essential for percutaneous closure of ASD using Amplatzer septal occluder. Dexmedetomidine (DEX), which is a highly selective α2-agonist, has sedative and analgesic properties without respiratory depression in the clinical dose range. We report percutaneous closure of ASD with TEE under DEX sedation.

    Right aortic arch (RAA) associated with isolated atrial septal defect (ASD) is very rare. We report successful closure of ASD associated with RAA using a 26-mm atrial septal occluder in a 30-year-old male patient. The impingement of right descending aorta in RAA caused malposition of the device in the left atrium. Deployment of the device through the right upper pulmonary vein successfully closed the defect. Follow-up evaluation by computerized tomography scan and echocardiogram showed no pulmonary venous obstruction

  6. Routine preoperative cardiac catheterization necessary before repair of secundum and sinus venosus atrial septal defects

    International Nuclear Information System (INIS)

    Between January 1976 and July 1983, 217 patients with atrial septal defect underwent surgical repair at Children's Hospital. Thirty with a primum atrial septal defect and 26 who underwent cardiac catheterization elsewhere before being seen were excluded from analysis. Of the 161 remaining patients, 52 (31%) underwent preoperative cardiac catheterization, 38 because the physical examination was considered atypical for a secundum atrial septal defect and 14 because of a preexisting routine indication. One hundred nine (69%) underwent surgery without catheterization, with the attending cardiologist relying on clinical examination alone in 5, additional technetium radionuclide angiocardiography in 5, M-mode echocardiography in 13 and two-dimensional echocardiography in 43; both M-mode echocardiography and radionuclide angiography were performed in 24 and two-dimensional echocardiography and radionuclide angiography in 19. Since 1976, there has been a trend toward a reduction in the use of catheterization and use of one rather than two noninvasive or semiinvasive techniques for the detection of atrial defects. Of the 52 patients who underwent catheterization, the correct anatomic diagnosis was made before catheterization in 47 (90%). Two patients with a sinus venosus defect and one each with a sinus venosus defect plus partial anomalous pulmonary venous connection, partial anomalous pulmonary venous connection without an atrial septal defect and a sinoseptal defect were missed. Of 109 patients without catheterization, a correct morphologic diagnosis was made before surgery in 92 (84%). Nine patients with a sinus venosus defect, three with sinus venous defect and partial anomolous pulmonary venous connection, four with partial anomalous pulmonary venous return without an atrial septal defect and one with a secundum defect were incorrectly diagnosed.(ABSTRACT TRUNCATED AT 250 WORDS)

  10. Retroperitoneal hematoma following rofecoxib and enoxaparin coadministration in a patient with atrial fibrillation

    International Nuclear Information System (INIS)

    There are very few published reports implicating enoxaparin as a factor in retroperitoneal hematoma. We report a patient who developed a retroperitoneal hematoma after using enoxaparin for paroxysmal atrial fibrillation. A 72 year old man was admitted with a history of low back pain, radiating beyond the back to the buttocks. His medical history was positive for bilateral knee osteoarthritis. On his physical examination his vital signs were: temperature 36.8, blood pressure 100/70 mm Hg, pulse 72/min, respiratory rate 16/min. X-ray of both the knees showed bilateral osteoarthritic changes. Computerized tomography scan of the spine showed lumbar spinal stenosis and he was referred to a Neurosurgeon, who finds the patient not fit surgical intervention. ECG showed atrial fibrillation. He was given enoxaparin one mg/kg every 12 hour and digoxin. Abdominal computed tomography revealed a right retroperitoneal hematoma and no aortic aneurysm was noted and enoxaparin and rofecoxib were discontinued. His general condition improved. The factors that increase the risk of bleeding in patients receiving enoxaparin are use of high doses of enxaparin, advanced stage, renal impairment, and the concomitant use of drugs affecting hemostasis. Retroperotoneal hematoma should be considered in the different diagnosis in patients receiving enoxaparin and experiencing unexplained decreases in hemoglobin and hematocrit. In the order of precedence of radiologic diagnostic procedures for fast diagnosis of a retroperitoneal hematoma, abdominal CT-scan is the preferred method

    Arrhythmogenic right ventricular cardiomyopathy is characterised by progressive, fibrofatty replacement of myocardium, and ventricular arrhythmias, and its prognosis is usually poor. Arrhythmogenic right ventricular cardiomyopathy associated with atrial septal defect is very rare, and this combination may make the diagnosis, treatment, and prognosis difficult. We present a case of a patient with this association who underwent interventional treatment with a septal defect occluder. Transcatheter closure of atrial septal defect in a patient with arrhythmogenic right ventricular cardiomyopathy is hitherto unreported. During a 3-year follow-up he remained relatively stable. We also review the cases reported in the medical literature describing this uncommon association between arrhythmogenic right ventricular cardiomyopathy and atrial septal defect or patent foramen ovale.

    Atrial tachyarrhythmia is a well-known long-term complication of atrial septal defect (ASD) in adults, even after successful trans-catheter closure. However, the risk factors for early-onset atrial tachyarrhythmia after trans-catheter closure remain unclear. This retrospective study enrolled adults with secundum ASD undergoing trans-catheter closure from January 2000 to March 2014. We analyzed the clinical characteristics of patients and assessed risk factors for new-onset atrial tachyarrhythmia defined as a composite of atrial fibrillation or flutter (AF/AFL) after ASD closure. We enrolled a total of 427 patients; 123 were male (28.8%) and the median age was 37.0 (interquartile range [IQR]: 18.3-49.0). Nineteen (4.4%) patients had documented atrial tachyarrhythmia during the follow-up period (median: 11.4 months [IQR: 5.4-24]). Patients with transient AF/AFL during closure showed a greater incidence of new-onset atrial tachyarrhythmia during the follow-up period than patients with consistent sinus rhythm during closure (27.3% vs 3.8%; P = 0.01). Most new-onset atrial tachyarrhythmias were documented within 6 months (median: 2.6 [IQR: 1.2-4.1] months) of closure. In the multivariate analysis, the risk for new-onset atrial tachyarrhythmia was significant in patients with AF/AFL during closure (hazard ratio [HR]: 9.90, 95% confidence interval [CI]: 2.86-34.20; P < 0.001), deficient posteroinferior rim (HR: 5.48, 95% CI: 1.15-25.72; P = 0.04), and age of closure over 48 years (HR: 3.30, 95% CI: 1.30-8.38; P = 0.01). In conclusion, transient AF/AFL during trans-catheter closure of ASD as well as deficient posteroinferior rim and age of closure over 48 years may be useful for predicting early new-onset atrial tachyarrhythmia after device closure.

    Full Text Available Introduction: We aimed to develop a classification method to discriminate ventricular septal defect and atrial septal defect by using severalhemodynamic parameters.Patients and Methods: Forty three patients (30 atrial septal defect, 13 ventricular septal defect; 26 female, 17 male with documentedhemodynamic parameters via cardiac catheterization are included to study. Such parameters as blood pressure values of different areas,gender, age and Qp/Qs ratios are used for classification. Parameters, we used in classification are determined by divergence analysismethod. Those parameters are; i pulmonary artery diastolic pressure, ii Qp/Qs ratio, iii right atrium pressure, iv age, v pulmonary arterysystolic pressure, vi left ventricular sistolic pressure, vii aorta mean pressure, viii left ventricular diastolic pressure, ix aorta diastolicpressure, x aorta systolic pressure. Those parameters detected from our study population, are uploaded to multi-layered artificial neuralnetwork and the network was trained by genetic algorithm.Results: Trained cluster consists of 14 factors (7 atrial septal defect and 7 ventricular septal defect. Overall success ratio is 79.2%, andwith a proper instruction of artificial neural network this ratio increases up to 89%.Conclusion: Parameters, belonging to artificial neural network, which are needed to be detected by the investigator in classical methods,can easily be detected with the help of genetic algorithms. During the instruction of artificial neural network by genetic algorithms, boththe topology of network and factors of network can be determined. During the test stage, elements, not included in instruction cluster, areassumed as in test cluster, and as a result of this study, we observed that multi-layered artificial neural network can be instructed properly,and neural network is a successful method for aimed classification.

    Background Whether the low molecular weight heparin microcapsule coated occluder is helpful to endothelialization in atrial-septal defect models is uncertain. This study aimed to investigate the best conditions for low molecular weight heparin coated Nil-I alloy occluder and provide the evidence of the efficacy and safety of atrial-septal defect occluders in vivo.Methods Low molecular weight heparin microcapsules were investigated using gelatin as microcapsule material. The prepared low molecular weight heparin gelatin particles were subjected to nickel and titanium alloy occluder coating by sodium hyaluronate. A dog model of atrial septal defects was established after treatment with low molecular weight heparin microcapsule coated occluder (n=4) and uncoated occluder (n=4). Endotheliocytes and fibroblastic cells in occluders were observed. And the rate of endothelialization was detected.Results When the concentration of gelatin was 1%, the diameters of particles were mostly about 100 pm, and the particle size was uniform. The envelope efficiency of low molecular weight heparin microcapsule was about 80%. The endothelialization of occluder in the model was more obvious in the coated group than in the uncoated group (P <0.0001).Conclusions Low molecular weight heparin can be prepared into microcapsules with their particle size in nanometric grade. The antithrombotic properties are kept in the nickel and titanium alloy occluder successfully coated with sodium hyaluronate. The endothelialization after the interventional occlusion in the coated group is obvious, indicating that low molecular weight heparin is helpful to the growth of endothelial cells in the occlude and the healing after the interventional occlusion.

    Full Text Available Introduction: Atrial septal defect (ASD is the most common congenital heart disease in adults and constitutes 5-10% of all congenital heart disease. Primary surgical closure has been the standard approach for many years with high success rate. Transcatheter closure of ASD in selected patients has became the contemprorary practice that has the advantages of short hospital stay and relative ease of prosedure. In this article, we reported the results of percutaneous closure of ASD in our center.
Methods: Between 2009-2011, thirty-two patients (mean age 36±18 years and 24 females who had secundum type ASD which detected by transthoracic echocardiography (TTE and transesophageal echocardiography (TEE were included in this study. Twenty-nine (90,6% patients were closed percutaneously. Tree patients were referred for surgery because of failure of percutaneous closure. Amplatzer Septal Occluder was used in 25 (86,2% patients and Occlutech device was used in other patients. All procedures were performed under local anesthesia. All of the patients were examined with TTE before the procedure and, at the 1st, 3rd, 6th and 12th month follow-up visits.
Results: Pre-operative mean pulmonary artery pressure was 33,3±7,5 mmHg and mean pulmonary to systemic flow (Qp/Qs ratio was 2,9±1,1. Mean ASD diameter measured by TEE was 20,1±6,6 mm and mean streched diameter measured by balloon catheter was 22,1±5,9 mm. Mean device size 24±6 mm (range 12-36 mm. In the follow-up period no major complication was observed, but mild to moderate residual shunt flow was detected in two patients (% 6,8.
Conclusion: Percutaneous ASD closure has been performed with high success and low complication rates in patients with secundum atrial septal defect in our center.

    Background and Purpose: An association between atrial septal aneurysm and embolic events has been suggested. Atrial septal aneurysm has been shown to be associated with patent foramen ovale and,.in some reports, with mitral valve prolapse. These two latter cardiac disorder; have been identified as potential risk factors for ischemic stroke. The aim of this prospective study was to assess the role of atrial septal aneurysm as an independent risk factor for stroke, especially for cryptogenic stroke. Methods: We studied the prevalence of atrial septal aneurysm, patent foramen ovale, and mitral valve prolapse in 100 consecutive patients aneurysm and patent foramen ovale relied on transesophageal echocardiography with a contrast study and that of mitral valve prolapse, on two-dimensional transthoracic echocardiography. Results: Stepwise logistic regression analysis showed that atrial septal aneurysm (odds ratio, 4.3; 95% confidence interval, 1.3 to 14.6; P=.01) and patent foramen ovale (odds ratio, 3.9; 95% confidence interval, 1.5 to 10; P=.003) but not mitral valve prolapse were significantly associated with the diagnosis of cryptogenic stroke. The stroke odds of a patient with both atrial septal aneurysm and patent foramen ovale were 33.3 times (95% confidence interval, 4.1 to 270) the stroke odds of a patient with neither of these cardiac disorders. For a patient with atrial septal aneurysm of >lo-mm excursion, the stroke odds were approximately 8 times the stroke odds of a patient with atrial septal aneurysm of aneurysm and patent foramen ovale are both significantly associated with cryptogenic stroke and that their association has a marked synergistic effect. Atrial septal aneurysms of >lo-mm excursion are associated with a higher risk of stroke. (Stroke. 1993;24:1865-1873.)

    Atrial septal aneurysm remains a rare congenital cardiac malformation. In the neonatal age group it can occur as an isolated cardiac malformation or in association with complex hypoplastic cardiac malformations of the right and left heart. In the adult population most aneurysms have been described in association with stroke. Baby H.N delivered on 10/05/2008 by C/S, was cyanosed at birth with systemic desaturation. Chest X-ray showed oligaemic lung fields while two dimensional echocardiograms showed tricuspid atresia with hypoplastic right ventricle, large secundum atrial septal defect, and highly mobile gigantic aneurysms of the atrial septum obstructing the inflow of the mitral valve and entering the left ventricle in diastole. Surgical intervention was not possible and child died on second day.

    Full Text Available Introduction. Transcatheter atrial septal defect (ASD closure is considered to be a gold standard for patients with the suitable anatomy as compared to cardiac surgery. Reocurrence of ASD after surgical closure is a very rare late complication which can be successfully managed with transcatheter procedure. Case report. We reported a female patient with Noonan syndrome who presented with hemodinamically significant ASD 37 years after the corrective cardiac surgery. Due to numerous comorbidities which included severe kyphoscoliosis, pectus excavatum and multiple surgeries we decided to perform transcatheter closure of ASD. The procedure itself was very challenging due to the patient’s short stature and heart’s orientation in the chest, but was performed successfully. The subsequent follow-up was uneventful and the patient reported improvement in the symptoms. Conclusion. Transcatheter closure of ASD in a patient with Noonan syndrome with the history of surgically corrected ASD can be performed successfully, despite challenging chest anatomy.

    We report the management of a patient with secundum atrial septal defect (ASD)and severe pulmonary hypertension.A 65-year-old male with recently diagnosed atrial serital defect was referred to our centre for decompensated right heart failure with rest and exercise induced dispnea and severe pulmonary hypertension.Right heart catheterization confirmed a mean pulmonary pressure of about 55 mmHg and a Qp/Qs of 2.7.An occlusion test with a compliant large balloon demonstrated partial fall of pulmonary arterial pressure.The implantation of a home-made fenestrated Amplatzer ASD Occluder (ASO) was planned in order to decrease lefttoright shunt and promote further decrease of pulmonary arterial pressure in the long-term.Thus,by means of mechanical intracardiac echocardiography study with a 9F 9 MHz Ultralce catheter(Boston Scientific Corp.),we selected a 34 mm ASO for implantation.Four millimeter fenestration was made inflating a 4 ntm non-compliant coronary balloon throughout the waist of the ASO,which was successfully implanted under intracardiac echocardiography.After six months,a decrease of pulmonary arterial pressure to 24 mmHg and full compensated right heart failure was observed on transthoracic echocardiography and clinical examination.This case suggests that transcatheter closure with home-made fenestrated ASD in elderly patients with severe pulmonary hypertension is feasible.

    Echocardiograms were performed in 80 infants and children with isolated ventricular septal defect (VSD) who underwent cardiac catheterization. The pulmonary-to-systemic flow ratio (Qp/Qs) was correlated with the echocardiographic left atrial-to-aortic root diameter ratio (LA/Ao), and a relatively poor correlation (r = 0.62) was found. The end-systolic diameters of the left atrium and aorta at the level of the aortic root, obtained from lateral cineangiograms of 55 of the 80 patients, were compared with the corresponding echocardiographic dimensions. To assess the possible effect of transducer beam angulation upon the echocardiographic determinations, the angiographic measurements were made at 0 degrees position (perpendicular to the frontal plane) and at angles of 5 degrees, 10 degrees, 15 degrees and 20 degrees from zero, using the aortic root center as the point of intersection. The echocardiographic and angiographic aortic root measurements were comparable (r = 0.95), and the angiographically derived aortic diameter did not vary with different angle projections. However, the left atrial angiographic dimensions were significantly influenced by the angle of projection. We conclude that the echocardiographic LA/Ao ratio cannot reliably estimate the severity of the shunt flow in VSD.

    Full Text Available Objective: Atrial septal defect (ASD is the most common congenital heart disease in adults. The aim of this study was to determine the value of surgical closure of ASD in patients over 40 years of age. Materials and Methods: Retrospective analysis of 96 patients with the mean age of 47.58 ± 6.59, who had undergone surgical repair of ASD, was carried out. Pre and postoperative clinical status, New York Heart Association (NYHA functional class and systolic pulmonary artery pressure before and after surgical repair, complications of post operation were assessed and analyzed. The follow-up period was between 1 month and 16 years. Results: Before the operations, 62 patients (89.8% were placed in NYHA functional classes of II and III. However, after the surgeries most of the patients could be placed in the functional classes I and II. The mean of pulmonary artery pressure before the surgeries was about 46.68 ± 14.18 and dropped to 32 ± 11.89 mm Hg after the operations (P < 0.0001. Atrial fibrillation rhythm was present in 18 cases preoperatively which was reduced to 3 patients at the discharge time (16.6%. The mean right ventricular (RV sizes were reduced from 4.1 to 2.5 cm after the surgical repairs. In 35 cases (36.64%, we had no tricuspid valve regurgitation after surgery for RV systolic presser estimation. Conclusion: Surgical closure of ASD in patients over 40 years of age could improve their clinical status, and lead to a reduced pulmonary systolic as well as smaller RV sizes.

    Full Text Available Background. The relevance of TBX20 gene in heart development has been demonstrated in many animal models, but there are few works that try to elucidate the effect of TBX20 mutations in human congenital heart diseases. In these studies, all missense mutations associated with atrial septal defect (ASD were found in the DNA-binding T-box domain, none in the transcriptional activator domain. Methods. We search for TBX20 mutations in a group of patients with ASD or ventricular septal defect (VSD using the High Resolution Melting (HRM method and DNA sequencing. Results. We report three missense mutations (Y309D, T370O, and M395R within the transcriptional activator domain of human TBX20 that were associated with ASD. Conclusions. This is the first association of TBX20 transcriptional activator domain missense mutations with ASD. These findings could have implications for diagnosis, genetic screening, and patient follow-up.

The patients' age was from 2 to 14years old (average 3.77±1.55). The body weight was from 9 to 48 Kg (average 21.53±10.63). When the devices were placed on the right position with difficulty and failure in some cases with short and soft rims of the defect and large defect and the angle between the device and the interval atrial septal (IAS), It could be helpful to put the device into the left upper pulmonary vein, and to make right atrium (proximal) disc opened before the left atrium (distal) disc naturally fall down.At the end the double disc of the device clamped and stood up at the right position of the IAS. After closure of ASD, patients were followed up regularly by echocardiography, X-ray and ECG in the 1,3,6,12month and 3,5 years. Results The successful rate of device implantation in the improving group (98.4%)was obviously higher than that in the regularly group (68%). The techniques improved in this group with the smaller age, the lighter weight, the larger defect and the larger device comparing with the regularly group.The velocity of the pulmonary vein before occlusion procedure was (0.54±0.15)m/s; after procedure was (0.56±0.16)m/s, P > 0.05,there were no significant difference. All cases couldn't found pulmonary congestion by follow up. Conclusions The method of controlling release of device in the pulmonary vein has been used more than 5 years in the occlusion of ASD with double disc device. It is feasible and safety. The aim of the improvement is

    Modest secundum atrial septal defects (2°ASD) may cause significant pulmonary over perfusion during infancy, particularly in conjunction with left heart obstructive lesions. Amplatzer Septal Occluders are not ideal in this setting especially given recent concerns regarding device erosion. We report the first use of the Amplatzer Duct Occluder II device (ADO2) to close a 2°ASD in a 4.5 kg infant.

    Objective To evaluate the dimensions of atrial septal aneurysm (ASA), the presence and characteristics of interatrial shunt, the movement of the wall of the aneurysm, and correlation between these findings and sign and/or symptoms suggesting embolism in Manisa, a district of a western Anatolian city of Turkey. Methods Two thousand five hundred cases were examined by routine transthoracic echocardiography (TTE) in both pediatric and adult cardiology outpatient clinics. ASA was detected in 20 cases and evaluated by two-dimensional color Doppler echocardiography (CDE). The length of the base, the maximum radius and the maximum displacement of ASA were measured. The shunt between the atria was examined by CDE. In cases where a shunt could not be found, galactose and palmitic acid was injected. Standard 12-lead electrocardiogram (ECG) and exercise stress test were also performed. Results No clinical signs or symptoms were found, suggesting a systemic or cerebral embolism. The maximum displacement of ASA was between 2 and 5 mm. All of the aneurysms were localized in the right atrium, and the walls of the aneurysm did not move beyond the base of the left atrium during the maximum displacement. Interatrial shunt was detected in 14 of 20 patients (70%) by CDE and in the remaining six cases by contrast TTE. Frequent ventricular ectopic beats were observed in one patient. Conclusions During routine TTE we observed 0.8% asymptomatic ASA in our population. The use of a contrast agent was found to be a valuable additional method in patients with ASA when the shunt could not be detected by CDE. The risk for embolism is not high when the maximum displacement of the wall of ASA was 5 mm or less and no bulge into the left atrium was observed. Based on our experience with this method, TTE is easy to perform, well-tolerated and acceptable.

    Full Text Available Background: Atrial Septal Defect (ASD is one of the most common congenital heart diseases that may lead to pulmonary hypertension. Advantages of ASD closure by limited thoracotomy as a minimally invasive approach includes reduction of post-operative complications and improvement of post-operative recovery. Objectives: The present study aimed to assess the safety of right submammary minithoracotomy for repair of ASD in children and to evaluate the cosmetic and functional results of this approach. Patients and Methods: Between August 2010 and August 2013, 35 children underwent heart operations for ASD closure via right submammary thoracotomy. The standard anterolateral thoracotomy technique entailed a 4 - 5 cm right submammary incision. After establishment of cardiopulmonary bypass, the right atrium was opened and defect was closed by pericardial patch. The thoracotomy was closed in a routine fashion. Results: The study patients included 5 males (14.29% and 30 females (85.71% whose age ranged from 1 to 7 years. Among the patients, 30 had ASD and 5 had a sinus venosus type. There were no intraoperative complications regarding exposure, cannulation, or bleeding. There were also no deaths in the post-operative period. Postoperative complications included significant hemorrhage from the suture line in one case and sick sinus syndrome requiring pacemaker implantation in another case. The mean length of stay in the intensive care unit was 2 days and the mean length of hospital stay was 4.5 days. Conclusions: Our study findings indicated that use of right submammary thoracotomy technique to repair ASD could be accomplished safely and provided good short-term results in terms of cosmetics, especially in female patients.

    Objective To study the validation of ultrasound-based strain rate imaging in the quantitative assessment of right ventricular (RV) function in atrial septal defect (ASD). Methods Tissue Doppler images (TDI) of RV longitudinal and short axes were recorded from the apical 4-chamber view and the subcostal short-axis view in 18 normal controls, 28 children with ASD and 14 children after Amplazter closure of ASD respectively. Peak systolic velocities (V), peak systolic strain rates (SR), peak systolic strains (S) at the basal segment, middle segment of RV lateral wall and the basal septum from the longitudinal axis, the middle segment of RV free wall from the short axis were quantitatively measured using QLAB TM tissue velocity quantification software system respectively. Peak dp/dt from the RV isovolumic contraction determined during the right cardiac catheterization in 28 ASD patients was used as the gold standard of RV contractility. Peak systolic indices were compared against max dp/dt by linear correlation. Results Peak systolic indices at the basal and middle segments of RV lateral wall from the longitudinal axis increased significantly in 28 ASD patients.Peak systolic indices at the basal septum also increased in patient group, but not significantly. Significant decreases in peak systolic indices at the basal and middle segments of RV lateral wall were observed after the Amplatzer closure in 14 ASD patients. There was no significant difference at the middle segment of RV free wall from the short axis between patient group and normal control. A strong correlation was found between max dp/dt and peak systolic indices at the basal and middle segments of RV lateral wall (P<0.05). Conclusion Ultrasound-based strain rate imaging can assess quantitatively RV function in CHD. Peak systolic strains determined at the basal and middle segments of RV lateral wall are strong noninvasive indices of RV contractility.

    Full Text Available Rhythms that derive from parts of atria other than the sinus node are called premature atrial contractions (PACs. Vast majority of fetal PACs are idiopathic. Fetal PACs usually have a good prognosis and disappear spontaneously during pregnancy or after delivery. Development of fetal tachycardia or fetal bradycardia is rarely reported during follow-up of fetuses diagnosed with PACs. To the best of our knowledge, coexistence of tachycardia and bradycardia leading to hemodynamic impairment has not yet been reported. We present a fetus diagnosed with PACs and atrial septal aneurysm (ASA on the 23rd week of gestation proceeding to fetal bradycardia and fetal tachycardia and consequently hemodynamic impairment. We suggest closer follow-up of fetuses with PACs accompanied by ASA.

  5. Real-time-MR guidance for placement of a self-made fully MR-compatible atrial septal occluder: in vitro test

    International Nuclear Information System (INIS)

    Purpose: This in vitro study investigated the feasibility to visualize the placement of three different atrial septal occluder systems using real-time MR control. Methods: The experiments were performed on an interventional 1.5 T high field whole body system. Real-time MR imaging was achieved by radial or spiral k-space filling in conjunction with the sliding window reconstruction technique yielding an imaging speed of 15 frames per second. The CardioSeal, Ampaltzer Septal Occluder and a specially designed MR-compatible closure device were tested in a water bath. A punctured plastic wall served as model for the atrial septal defect. Results: The delivery systems of the CardioSeal and Amplatzer Occluder were ferromagnetic and caused substantial artifacts, making the device placement impossible, even if the magnetic forces would have been acceptable. The self-made prototype caused only minor susceptibility artifacts allowing its visualization on the MR images. The MR imaging techniques applied enabled real-time control of the occluder including steering through the artificial septal foramen and visualization of the occluder deployment. Conclusion: Real-time MR imaging allows for guidance and placement of an MR-compatible septal occluder in vitro suggesting the feasibility to perform atrial septal occlusion under MR-guidance in vivo as well.

    A 52-year-old man was diagnosed with dextrocardia at the age of 1 year and was asymptomatic until 1 year before admission. He was transferred to our hospital for management of atrial fibrillation. A transthoracic echocardiogram showed dextrocardia with atrial septal defect;moderate tricuspid valve regurgitation; and a large, persistent left superior vena cava. A cardiac catheterization study revealed that pulmonary flow/systemic flow (Qp/Qs) was 3.6 and that pulmonary vascular resistance was 2.5 Wood U·m². Intracardiac repair with tricuspid annuloplasty and a maze procedure was scheduled. When establishing cardiopulmonary bypass, venous drainage was initially obtained from the inferior vena cava and the left superior vena cava, and the small superior vena cava was then directly cannulated after opening the right atrium. The patient's postoperative course was uneventful, and serial electrocardiograms have demonstrated maintenance of normal sinus rhythm for 3.5 years after the operation.

    Full Text Available Michael Emery1, Waqas Ghumman1, Shawn Teague2, Jo Mahenthiran11Krannert Institute of Cardiology, 2Department of Radiology, Indiana University School of Medicine, Indianapolis, Indiana, USAAbstract: A 23-year-old male referred for evaluation of a “choking” sensation with exertion and a murmur. A transthoracic echocardiogram demonstrated right atrial and ventricular dilatation, right ventricular volume overload, and a large secundum atrial septal defect (ASD with left to right shunt and a calculated pulmonary-to-systemic blood flow ratio (Qp/Qs estimated at 2.3 to 1. Cardiac catheterization also demonstrated evidence of the ASD with Qp/Qs of 4.6 to 1 with a significant step-up in oxygen saturation at the right atrial level. Additionally, an anomalous left main coronary artery (ALMCA origin from the anterior right coronary cusp was suspected. Using 64-slice multidetector computed tomography coronary angiography (CCTA the left main coronary artery was seen to arise from the right coronary cusp then traverse between the pulmonary trunk and the proximal ascending aorta before bifurcating into the left anterior descending and circumflex arteries that followed their normal courses distally. Based on the high risk nature of associated sudden death from an anomalous left main coronary artery (ALMCA coursing between the aorta and the pulmonary trunk, the patient underwent surgical re-implantation of the ALMCA to the left coronary cusp and repair of the ASD. This case highlights a rare finding of a hazardous ALMCA in a patient with a secundum ASD and the utility of CCTA in evaluating the course of coronary anomalies along with other cardiac pathology.Keywords: atrial septal defect, anomalous coronary artery, congenital heart disease

  8. Interatrial shunt. Diagnosis of patent foramen ovale and atrial septal defect with 64-row coronary computed tomography angiography

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the frequency with which interatrial shunts are found during routine coronary computed tomography (CT) angiography and to describe imaging characterizations of patent foramen ovale (PFO), atrial septal defect (ASD), and atrial septal aneurysm (ASA). A total of 1081 adult patients were evaluated retrospectively for interatrial shunting; 77 were excluded from the study. CT diagnosis of PFO was defined as (1) a channel-like appearance of the interatrial septum (IAS) and (2) a contrast agent jet flow from the left atrium (LA) to the right atrium (RA). ASD was defined as (1) the IAS resembling a membrane with a hole and (2) a contrast jet flow between the two atria. ASA was identified by detecting a minimum 10-mm protrusion of the LA beyond the IAS into the RA. Among 1004 patients, 86 patients (8.6%) were diagnosed to have PFO. Another 23 patients (2.3%) had a hole in the IAS and were diagnosed as having ASD: 21 with an ostium secundum-type ASD and 2 with the sinus venosus type. ASA accompanied ASD in three patients. Electrocardiography-gated CT using the saline-chaser contrast injection technique that is routinely used for coronary arterial imaging can be used to detect interatrial shunts. The technique can also serve as a method for differentiating PFO, ASD, and ASA. (author)

The advantages when compared to surgical closure include a shorter procedure time and hospital stay and no scarring. This mode of treatment was not available in Nigeria prior to the cases reported here, requiring patients to travel abroad for the procedure.Methods: A cardiac catheterization laboratory became available in Lagos, Nigeria in 2009, and in December 2010 the laboratory collaborated with Lagos State University College of Medicine and Lagos State University Teaching Hospital to perform the device closure on two women (aged 34 and 62 years with secundum ASD. To the best of our knowledge, these are the first times the procedure has been performed in Nigeria.Results: Both patients made successful recovery and are stable.Conclusion: Transcatheter closure of ASD is now safe and available in Nigeria.Keywords: atrial septal defect, transcatheter closure, Nigeria

  10. Hybrid management of a large atrial septal defect and a patent ductus arteriosus in an infant with chronic lung disease

    International Nuclear Information System (INIS)

    We report a case wherein a dysmorphic four-month-old infant (weighing 4.5 kgs) with an 8 mm atrial septal defect (ASD), a 1.5 mm patent ductus arteriosus (PDA), a 2 mm mid-muscular ventricular septal defect (VSD) associated with chronic lung disease, and severe pulmonary hypertension, was successfully managed using a hybrid approach, without the use of cardiopulmonary bypass (CPB). Through a median sternotomy, the PDA was ligated and the ASD was closed with a 9 mm Amplatzer septal occluder implanted through peratrial access. The VSD was left untouched. Serial echocardiograms showed complete closure of the ASD and PDA, with progressive normalization of the pulmonary artery (PA) pressures within three months. The child rapidly gained weight and was weaned from sildenafil and oxygen administration. After 12 months, the VSD closed spontaneously and the child remained well, with normal PA pressures. A hybrid approach without the use of CPB should be considered in the management of infants with congenital heart disease, associated with chronic lung disease and pulmonary hypertension

    Full Text Available Objective:Transcatheter closure of secundum atrial septal defect (ASD with Amplatzer device is an alternative procedure to surgical repair, with some limitations. The aim of this study was to assess the initial and mid-term results of the treatment of ASD with Amplatzer septal occluder in children and adolescents. Methods:From May 2003 to January 2008 sixty three consecutive children and adolescent patients underwent transcatheter closure of ASD at a mean±SD age of 8.5±4.8 years (range 2.2 to 18 years. All procedures were performed under local anesthesia and moderate sedation or general anesthesia with transthoracic echocardiography and fluoroscopic guidance. Stretch diameter of ASD was determined by balloon sizing catheter. Device selection was based on and matched to the standard diameter of the septal defect. Follow up at 24 hours, 1 month, 6 months, 12 months and yearly thereafter included physical examination, electrocardiography and transthoracic echocardiography. Findings:The mean ASD diameter, measured with transthoracic echocardiography and balloon catheter were 19.5± 5.5 mm and 20.9± 6.2 mm, respectively. The mean follow up period was 32.4±18.8 months. Deployment of the device was successful in 57 (90.5% and failed in 6 (9.5% patients. The major complication included dislodgement of device in 1 patient and device embolization to right ventricular inlet (surgically removed in 1 patient. The minor complication included transient atrial tachycardia in 10 patients, paroxysmal supraventricular tachycardia in 2 patients during procedure, successfully terminated with medication. At 24 hour, 1 month, 6 month and 1 year follow up, total occlusion rates were 73.6 %, 91%, 94.7%, and 94.7%, respectively. Conclusion:Transcatheter occlusion of ASD with Amplatzer device is an effective and safe procedure with minimal complication rate and short hospital stay, as well as excellent short and intermediate outcome in children and adolescents.

    International Nuclear Information System (INIS)

    To examine changes of ventilation and perfusion distribution before and after closed surgery in atrial septal defect (ASD), a total of 25 ventrilation-perfusion lung scintigraphies were performed in a supine position in 15 ASD patients. Their ages ranged from one year and 11 months to 23 years (an average age of 7 years and one month). Ventilation and perfusion distribution was almost uniform before surgery. Preoperative time constant obtained from Xe-133 washout curve had a positive correlation with pulmonary blood flow per pulmonary volume. Although preoperative higher perfusion was seen in the upper lobe, perfusion tended to be uniform after surgery. Non-uniform distribution of ventilation/perfusion ratio became uniform within a few weeks after surgery. (N.K.)

    Full Text Available Sinus venosus atrial septal defects (SV-ASD have nonspecific clinical presentations and represent a diagnostic imaging challenge. Transthoracic echocardiography (TTE remains the initial diagnostic imaging modality. However, detection rates have been as low as 12%. Transesophageal echocardiography (TEE improves diagnostic accuracy though it may not detect commonly associated partial anomalous pulmonary venous return (PAPVR. Cardiac magnetic resonance (CMR imaging provides a noninvasive, highly sensitive and specific imaging modality of SV-ASD. We describe a case of an adult male with exercise-induced, paroxysmal supraventricular tachycardia who presented with palpitations and dyspnea. Despite nondiagnostic imaging results on TTE, CMR proved to be instrumental in visualizing a hemodynamically significant SV-ASD with PAPVR that ultimately led to surgical correction.

    Full Text Available Background: Transcatheter closure of atrial septal defect secundum (ASD-II has become an alternative method for surgery. We sought to compare the two-dimensional transesophageal echocardiography (TEE method for measuring atrial septal defect with balloon occlusive diameter (BOD in transcatheter ASD-II closure.Methods: A total of 39 patients (71.1% female, mean age: 35.31 ± 15.37 years who underwent successful transcatheter closure of ASD-II between November 2005 and July 2008 were enrolled in this study. Transthoracic echocardiography (TTE and TEE were performed to select suitable cases for device closure and measure the defect size before the procedure, and BOD measurement was performed during catheterization via TEE. The final size of the selected device was usually either equal to or 1 – 2 mm larger than the BOD of the defect.Results: The mean defect size obtained by TEE and BOD was 18.50 ± 5.08 mm and 22.86 ± 4.76 mm, respectively. The mean difference between the values of ASD size obtained by TEE and BOD was 4.36 ± 2.93 mm. In comparison with BOD, TEE underestimated the defect size in 94.9%, but TEE value being equal to BOD was observed in 5.1%. There was a good linear correlation between the two measurements: BOD = 0.773 × ASD size by TEE+8.562; r2 = 67.9.1%. A negative correlation was found between TEE sizing and the difference between BOD and TEE values (r = -0.394, p value = 0.013.Conclusion: In this study, BOD was larger than ASD size obtained by two-dimensional TEE. However, TEE maximal defect sizing correlates with BOD and may provide credible information in device size selection for transcatheter ASD closure.

  16. The role of MRI for the evaluation of atrial septal defects before and after percutaneous occlusion with the Amplatzer Septal Occluder trademark

    International Nuclear Information System (INIS)

    Purpose: Evaluation of morphologic and functional MRI of atrial septal defects (ASD) before and after percutaneous occlusion with the Amplatzer Septal Occluder (AOC). Comparison of MRI with transesophageal echocardiography (TEE), balloon measurement (IVBM) and cardiac catheterization with shunt quantification (CCSQ). Materials and Methods: Twenty patients with ASD were examined before and three months after AOC implantation. ECG-triggered, breath-hold T1-weighted Turbo Spin Echo Segmented FLASH 2D and dynamic turbo-FLASH-GRE sequences after application of 0,2 mmol gadolinium DTPA per kg body weight were obtained in a 1.5 T MRI system. Defect size, and distance to coronal sinus (CS) and right upper pulmonary vein (RUPV) were determined for pre-interventional planning, and the AOC size was measured quantitatively for post-interventional follow-up. The shunts were evaluated qualitatively (occurrence of jets), semiquantitatively (jet length, turbulence square product) and quantitatively (flow measurement in the thoracic aorta and in the left and right pulmonary arteries). Results: The average size of the ASD measured by MRI was 17.6 mm (11-24.8 mm) in the axial view, 15.9 mm (10.8-28.9 mm) in the sagittal view and 16.4 mm (12.1-24.8 mm) in the short axis view. In comparison, the average defect size was 15 mm (8-24 mm) by TEE and 20 mm (13-27 mm) by IVBM. The average distance to the RUPV was 17 mm (9.6-21.9 mm) and to the CS 11.2 mm (5-17 mm). The AOC was visualized with only minimal artifacts. Qualitative analysis of the MRI findings revealed an occurence of jets in 17/20 patients. Semiquantitative analysis documented a high correlation for jet length and square product of the turbulence to defect size r=0.81 resp. r=0.82. Mean QP/QS-ratio measured by MR-volumetry was 1.6±0.29 and by MR-flow 1.6±0.26. The corresponding measurements were 1.7±0.3 for TEE and 1.5±0.5 for CCSQ. In comparison to TEE, the correlation coefficient was r=0.96 for MR-volumetry and r=0.85 for

    Full Text Available Background: Transcatheter closure of atrial septal defects (ASD has been accepted world-wide as an alternative to surgical closure with excellent results. This interventional, non-surgical technique plays an important role in the treatment of ASD mostly in the developing world where resources are limited. Objectives: To report the outcomes and short term follow-up of transcatheter closure of ASD over a 12-year period at our institution with limited resources. Patients and Methods: This retrospective study included all patients with the diagnosis of secundum ASD and significant shunting (Qp/Qs > 1.5:1 as well as dilated right atrium and right ventricle who had transcatheter closure at Integrated Cardiovascular Center (PJT, Dr. Cipto Mangunkusumo Hospital between October 2002 and October 2014. One hundred fifty-two patients enrolled in this study were candidates for device closure. Right and left heart cardiac catheterization was performed before the procedure. All patients underwent physical examination, ECG, chest X-ray and transthoracal echocardiography (TTE prior to device implantation. Results: A total of 152 patients with significant ASD underwent device implantation. Subjects’ age ranged from 0.63 to 69.6 years, with median 9.36 years and mean 16.30 years. They consisted of 33 (21.7% males and 119 (78.3% females, with mean body weight of 29.9 kg (range 8 to 75; SD 18.2.

    Vessels of Wearn are rare findings during coronary angiography in adults. They are known to be associated with forms of cyanotic congenital heart disease in infants but we are not aware of any published cases of association with non-cyanotic left to right shunts in adults. We present the case of a 69-year-old man with angiographically evident vessels of Wearn draining from the left and right coronary arteries into the left ventricle associated with an asymptomatic atrial septal defect. We postulate a developmental phase association between atrial septal maturation and closure of perfusing microchannels from the ventricular cavities to the epicardial coronary arteries on the same spectrum as that which leads to more widespread defects in infants. We also highlight a common medication side effect that might have been mistaken as a manifestation of the congenital anomalies.

    Full Text Available Abstract Introduction Fat embolism syndrome with respiratory failure after intramedullary nailing of a femur fracture is a rare but serious complication in trauma patients. Case presentation We present the case of a 20-year-old Caucasian man who experienced paradoxical cerebral fat embolism syndrome with fulminant progression after intramedullary nailing of a femur fracture, in conjunction with a clinically asymptomatic atrial septal defect in a high position resulting in a right-to-left shunt. Conclusion Fat embolism syndrome may occur as a fulminant complication following femoral fracture repair in the presence of a concomitant atrial septal defect with right-to-left shunt. Thus, in patients with cardiac right-to-left shunts, femurs should not be nailed intramedullary, not even in cases of isolated injuries.

  20. A novel snare assistance safeguards against early embolization of devices and facilitates quick retrieval of malpositioned devices in atrial septal defects with deficient margins

    Background : Embolization might complicate device closure of large atrial septal defects (ASDs) with deficient margins. When margins are deficient, a precariously placed device can appear to be held in good position by the rigid delivery cable. Once the cable is unscrewed, the device adopts the natural lie of the interatrial septum. This can occasionally expose the inadequately captured margins and lead to device embolization. Most embolizations occur immediately after release. Retrieval of t...

    The diagnosis of multiple atrial septal defects is less challenging with 3-D transesophageal echocardiography. However, the common occurrence of echo drop-out (acoustic shadow) artifacts with 3-D echocardiography can make the differentiation between a second defect and an artifact challenging. Agitated saline injection with direct visualization using 3-D echocardiography can help resolve this by allowing visualization of the bubbles crossing from true defects.

    Although previous studies showed that transthoracic echocardiography (TTE) can be used to guide transcatheter closure of atrial septal defect (ASD), whether TTE can be used to guide transcatheter closure of secundum ASD with a deficient superior-anterior rim is unknown and this critical issue was addressed in the present study. A total of 280 patients with secundum ASD who underwent transcatheter ASD closure were recruited and divided into groups A and B depending on ASD superior-anterior rim>4 mm (n = 118) or ≤4 mm (n = 162). TTE was used to guide Amplatzer-type septal occluder (ASO) positioning and assess residual shunt. Procedure success was defined as no, trivial and small residual shunt immediately after the procedure as assessed by color Doppler flow imaging. Group A and group B did not differ in complication rate (8.55% vs.7.55%), procedure success rate (98.3% vs. 95.0%) or complete closure rate immediately after the procedure (89.7% vs. 89.3%) or at 6-month follow-up (98.3% vs. 96.8%). The mean procedure and fluoroscopy time in group B were much longer than those in group A. In conclusion, the absence of a sufficient superior-anterior rim in patients undergoing percutaneous closure of secundum-type ASDs using fluoroscopic and TTE guidance is associated with slightly greater device malposition and migration as well as increased procedural and fluoroscopic times, but the overall complication rate did not differ with TTE guidance when compared to historical controls that used TEE guidance.

    @@ Massive calcification of left atrium is an uncommon complication of long-standing rheumatic valvular disease, and is most often observed in patients with a previous operation on mitral valve.1 Most patients have experienced symptoms for more than 15 years.2 Massive calcification of the left atrium generally spared the interatrial septum in the previous studies.4 However, to our knowledge, fewer than five cases have presented as full left atrial calcification (Table).

    Full Text Available A hypertensive 76-year-old man with severe pulmonary valve stenosis (PVS and recent initiation of haemodialysis was referred with fever, chills, and asthenia. One month prior, he had been admitted with similar symptoms. Transthoracic echocardiography (TTE had shown a PVS and no valve vegetations were observed. Following discharge, he was readmitted with fever and blood cultures positive for Staphylococcus haemolyticus. A new TTE revealed two pulmonary valve vegetations and a previously undetected ostium secundum-type atrial septal defect (ASD, confirmed by transesophageal echocardiography. The clinical course was uneventful with intravenous antibiotic treatment and the patient was safely discharged. This is a case of pulmonary valve infective endocarditis (IE. The incidence of right-sided IE is on the rise due to the increased number of patients using central venous lines, pacing, haemodialysis and other intravascular devices. Pulmonary valve IE is extremely rare, especially in structurally normal hearts. The case reported here, presents a combination of predisposing factors, such as severe congenital PVS, the presence of a central venous catheter, and haemodialysis. The fact that it was an older patient with severe congenital PVS and associated with a previously undiagnosed ASD, is also an unusual feature of this case, making it even more interesting.

  7. Preventive echocardiographic examination in athletes and workers – Quadricuspid aortic valve and atrial septal aneurysm in a young basketball player

    Full Text Available Ensuring safety of young athletes and employees who perform hard physical work within the scope of their professional duties, with a special focus on prevention of a sudden cardiac death at sports fields or during hard physical work is one of the most important tasks, which demands joint effort of cardiologists and sport physicians or occupational physicians, who qualify patients for a job or a sport discipline. Apart from hypertrophic and arhythmogenic right ventricular cardiomyopathy, coronary anomalies and aortic dissection belong to the most frequent causes of dramatic complications during competitive exercise or work with an increased energy expenditure. Although a detailed medical history and a physical examination combined with 12-lead ECG assessment may significantly improve the safety in competitive sports, adding echocardiography examination gives a detailed and noninvasive insight into the heart morphology and function. Therefore, in our opinion, it should constitute a standard part of the evaluation of candidates for competitive sports. The practice indicates that beyond subjects with severe heart diseases and those classified as normal, there is a group of individuals with abnormalities which should be more closely monitored, but are not contraindications against professional sports or work with an increased energy expenditure. We describe the case of a young female with a diagnosis of rare congenital aortic valve disease, quadricuspid valve, with mild regurgitation and atrial septal aneurysm which was established during transthoracic echocardiography and confirmed and expanded during TEE examination.

    A combination of tetralogy of Fallot( TOF) and total anomalous pulmonary venous return(TAPVR) is rare and results in chronic volume and pressure load of the right side of the heart and underfilling of the left heart. We report a successful 2-staged surgical correction of TOF associated with TAPVR and atrial septal defect. The patient was unsuitable for total primary intracardiac correction because the volume of the left ventricle was considered to be small. First, repair of anomalous pulmonary venous return and palliative right ventricle outflow tract reconstruction were simultaneously performed in 2 months of birth. One year after 1st operation, cardiac catheterization revealed that normalization of left ventricle volume, so 2nd operation was planned. Total correction of ventricular septal defect and right ventricle outflow reconstruction was performed and the patient was discharged on the 21st postoperative day with good hemodynamic status.

    Background While echocardiography has been a pivotal screening test in pulmonary arterial hypertension (PAH),the presence of structural cardiac defects may affect the ability to reliably predict pulmonary artery pressures (PAPs).This study sought to evaluate the accuracy of Doppler echocardiography (DE) for estimating PAPs in adult atrial septal defect (ASD) patients with PAH.Methods A prospective study was carried out to compare the echocardiographic assessment of PAP with the same pressures obtained by right heart catheterization (RHC) in adult ASD patients with PAH who underwent simultaneous DE and RHC.Bland-Altman analyses were performed to evaluate the agreement between DE and RHC measurements of PAPs.Results Two hundred and fifty-seven patients were included in the study.A significant overestimation of the systolic pulmonary arterial pressure (sPAP) and mean pulmonary artery pressure (mPAP) was reported by echocardiography compared with those by catheterization ((81.8±26.9) mmHg vs.(72.9±26.9) mmHg,P <0.01; (51.9±16.4) mmHg vs.(41.4±17.2) mmHg,P <0.01,respectively).Twenty-one percent (55/257) of the patients had PAH when estimated by echocardiography whereas showed normal results in the subsequent catheterization test.Using Bland-Altman analytic methods,the bias for the echocardiographic assessment of the sPAP was 9.1 mmHg with 95% limits of agreement ranging from-24.4 to 42.6 mmHg.For mPAP measurement,the bias was 10.5 mmHg with 95% limits of agreement ranging from-12.4 to 33.4 mmHg.On multiple linear regression analysis,age,gender,body surface area,ASDs' diameter,PVR,diastolic blood pressure,and echocardiographic assessment of right atrial pressure (RAP) explained 68.8% of the total variability in the model (r2=0.688,P <0.01).Conclusion Inaccuracy was frequently reported in Doppler echocardiographic assessment of the PAP in adult ASD patients with PAH and was often associated with age,gender,body surface area,ASDs' diameter

    Background Very few published data is available on the outcomes of balloon assisted techniques (BATs) for trans catheter closure (TCC) of very large (Defined as ≥35 mm size) ostium secundum atrial septal defect (ASD). Objective To study the utility of BAT as against conventional techniques (CT) in TCC of very large ostium secundum ASD (≥35 mm) over the past 5-year period and to find out the association of different morphological features of the defects in relation to TCC outcomes. Study design and methods Descriptive single center retrospective study of patients with very large ostium secundum ASD (≥35 mm size) who were subjected to TCC. Results Thirty-three out of 36 patients with ≥35 mm ASD and complex morphological features underwent successful TCC. The study patients had high prevalence of absent aortic and posterior rims with posterior mal-alignment of the septum. BAT was successful in 28/31 (90.3%) patients while CT had a success rate of 16%. The mean trans-esophageal echocardiography (TEE) ASD size with BAT success 37 (SD 1.3) mm and CT failure 36.2 (SD 1.1) mm was not different (P=0.06). On univariate analysis of different morphological features, posterior mal alignment of the septum was associated failure of CT (P=0.01). There was no urgent referral for surgery and patients did well on follow up. Conclusions Balloon assisted device closure of (≥35 mm) ASD had 90% success rate. BAT helps in controlled delivery and device alignment in very large ASD with posterior malalignment of the septum and is often helpful when CT fails. PMID:24649421

  13. Safety and efficacy of nano lamellar TiN coatings on nitinol atrial septal defect occluders in vivo

    International Nuclear Information System (INIS)

    Atrial septal defect (ASD) occlusion devices made of nickel–titanium (NiTi) have a major shortcoming in that they release nickel into the body. We modified NiTi occluders using Arc Ion Plating technology. Nano lamellar titanium–nitrogen (TiN) coatings were formed on the surfaces of the occluders. The safety and efficacy of the modified NiTi occluders were evaluated in animal model. The results showed that 38 out of 39 rams (97%) survived at the end of the experiment. Fibrous capsules formed on the surfaces of the devices. Gradual endothelialization took place through the attachment of endothelial progenitor cells from the blood and the migration of endothelial cells from adjacent endocardium. The neo-endocardium formed more quickly in the coated group than in the uncoated group, as indicated by the evaluation of the six month study group. After TiN coating, there was no significant difference in endothelial cell cycle. TiN coating significantly reduced the release of nickel in both in vivo and in vitro indicating an improved biocompatibility of the nitinol ASD occluders. Superior and modified ASD occluders may provide a good choice for people with nickel allergies after sFDA registration, which is expected in one to two years. - Highlights: ► The nano lamella TiN coating did not change the shape-memory behavior and flexibility of the nitinol occluder. ► Nano lamella TiN coating modifications significantly reduced nickel release from nitinol ASD occluder. ► The new ASD occluder was found to be superior to nitinol ASD occluder with respect to both safety and efficacy

  20. Atrial septal defects type II: noninvasive evaluation of patients before implantation of an amplatzer septal occluder and on follow-up by magnetic resonance imaging compared with TEE and invasive measurement

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate morphological and functional MRI of atrial septal defects (ASD) before and after interventional occlusion by the Amplatzer Septal Occluder (AOC) in comparison to trans-oesophageal echocardiography (TEE), invasive balloon measurement (IVBM) and cardiac catheterisation (QCC). Sixty patients with an ASD type II were enrolled. They underwent TEE, IVBM, QCC and MRI at 1.5T. Cine gradient echo, steady-state free precession sequences and a gradient echo phase contrast sequence were used. In MRI, pulmonary-to-systemic flow ratio (Qp/Qs) was calculated and compared with the QCC Qp/Qs ratio. Qp/Qs ratio in baseline MRI examination was 1.56 ± 0.29 (range: 1.05-2.2) and in QCC 1.71 ± 0.30 (range: 1.2-2.4) with a significant correlation (R = 0.65, P < 0.01). Defect size on MRI was 15.3 ± 7.4 mm (range: 3-30 mm), in TEE 14.3 ± 4.9 mm (range: 4-24 mm), and the balloon stretched diameter in IVBM was 23.4 ± 4.2 mm (range: 14-32 mm). Correlation between defect size in MRI vs. TEE was R = 0.67 (P < 0.01) and MRI vs. IVBM was R = 0.77 (P < 0.01). Right ventricular volumes decreased after intervention. MRI is an accurate noninvasive test for diagnosis, planning and follow-up after interventional ASD occlusion using an AOC. (orig.)

    Objective In patients with hypertrophic obstructive cardiomyopathy (HOCM), left atrial (LA) volume measurement is very important to provide prognostic information. Recent studies demonstrated that multidetector CT (MDCT) is useful to assess the changes in LA volume. Our aim was to examine the utility of a follow-up cardiac MDCT for long-term evaluation of the effect of percutaneous transluminal septal myocardial ablation (PTSMA) on LA volume. Methods We studied a consecutive cohort of 20 pati...

    Full Text Available Neonatal asymptomatic suprarrenal hemorrhage is relatively frequent; sometimes it is detected only after resolution when a calcification is found; symptomatic forms are rare; most times hemorrhage and hematoma are due to an obstetric trauma and are related to macrosomia, breech presentation, maternal diabetes and neonatal hypoxia. Clinical picture is characterized by abdominal mass and anemia; diagnosis is confirmed by imagenology. Two patients with suprarrenal hematoma from the University Hospital at Cartagena, Colombia, are presented. Both were related with traumatic delivery and cephalohematoma; one of them had oral and gastric bleeding and the othersuffered hematoma infection; diagnosis was done with abdominal ecography and CAT. Both patients recovered with medical treatment. La hemorragia suprarrenal asintomática del neonato es relativamente frecuente y muchas veces se detecta como una calcificación local después de que se resuelve el hematoma. La forma sintomática es rara y, a menudo, se debe a un trauma obstétrico relacionado con la macrosomía fetal, la presentación podálica, la diabetes materna o la hipoxia perinatal. Las manifestaciones clínicas son, principalmente, una masa abdominal y anemia importante; el diagnóstico se confirma con la imaginología. Se presentan dos casos de hematoma suprarrenal derecho tratados en el Hospital Universitario de Cartagena, ambos relacionados con un parto traumático y acompañados de cefalohematomas; uno de ellos presentó sangrado gastrointestinal alto y el otro infección del hematoma suprarrenal. El diagnóstico se comprobó con la ecografía abdominal y se verificó con la tomografía. El tratamiento fue médico y no se requirió cirugía a pesar de la anemia severa que presentó uno de los pacientes.

    Rhythms that derive from parts of atria other than the sinus node are called premature atrial contractions (PACs). Vast majority of fetal PACs are idiopathic. Fetal PACs usually have a good prognosis and disappear spontaneously during pregnancy or after delivery. Development of fetal tachycardia or fetal bradycardia is rarely reported during follow-up of fetuses diagnosed with PACs. To the best of our knowledge, coexistence of tachycardia and bradycardia leading to hemodynamic impairment has ...

    Full Text Available Objective: Review of intraoperative anesthetic challenges and the role of transesophageal echocardiography in children with sinus venosus atrial septal defect and partial anomalous pulmonary venous drainage undergoing Warden repair. Design: A retrospective observational case series. Methodolgy: Pediatric patients who underwent Warden repair between October 2011-September 2015 were recruited. Their preoperative clinical details, anesthetic techniques, intraoperative TEE findings and postoperative events were recorded from the medical records. The categorical variables and the continuous variables were expressed as number (percentages and mean ΁ SD respectively. Results: A total of 35 patients were operated for Warden repair during the study period. Anesthesia was induced with the aim to prevent any fall in pulmonary vascular resistance. The right internal jugular vein was cannulated under ultrasound guidance using a short length cannula to monitor right superior vena cava pressure. Intraoperative TEE revealed the drainage of PAPVC high into RSVC in 22 patients. Persistent LSVC was found in 9 patients. After repair, TEE imaging detected a high gradient at Warden anastomotic site in 5 patients and 3 of them required revision of surgery. Rerouted pulmonary veins required surgical correction in 2 patients in view of obstruction. None of them had pulmonary venous and SVC obstruction in the postoperative period. Conclusion: The primary aim of anesthesia is to avoid any fall in PVR. Right IJV cannulation can be beneficial. The intraoperative TEE can help in delineating the anatomy of lesion and detecting anastomotic site obstruction.

    GATA4 is expressed early in the developing heart where it plays a key role in regulating the expression of genes encoding myocardial contractile proteins. Gene mutations in the human GATA4 have been implicated in various congenital heart defects (CHD), including atrial septal defect (ASD). Although ASD is the third most common CHD in humans, it is generally rare in dogs and cats. There is also no obvious predilection for ASD in dogs and cats, based on sex or breed. However, among dogs, the incidence rate of ASD is relatively high in Samoyeds and Doberman Pinschers, where its inheritance and genetic aetiology are not well understood. In this study, we identified and investigated the genetic aetiology of an ASD affected family in a pure breed dog population. Although the GATA4 gene was screened, we did not find any mutations that would result in the alteration of the coding sequence and hence, the predicted GATA4 structure and function. Although the aetiology of ASD is multifactorial, our findings indicate that GATA4 may not be responsible for the ASD in the dogs used in this study. However, this does not eliminate GATA4 as a candidate for ASD in other dog breeds.

Postnatal array CGH demonstrated a 6.8 Mb terminal deletion at 8p23.3-p23, an interstitial 31.1 Mb duplication within 8p23.1-p11, and a terminal duplication of 0.24 Mb at 22q13.33, refining the karyotype to 46,XY,der(8)dup(8)(p23.1p11.1)t(8;22)(p23.1;q13.1).ish der(8)dup(8)(p23.1p11.1)t(8;22)(p23.1;q13.1) (D8S504-,MS607 + ,ARSA + ,D8Z1 + , RP115713 + +). Previous reports of distal 8p deletion, 8p duplication, and distal 22q duplication have shown similar manifestations, including congenital heart disease, intellectual impairment, and multiple minor anomalies. We correlate the patient's clinical findings with these particular areas of copy number. This case study supports the use of aCGH to identify subtle chromosomal rearrangement in infants with cardiac malformation as their most significant or only apparent birth defect. Additionally, it illustrates why aCGH is essential in the description of chromosome rearrangements, even those seemingly visible via routine karyotype. This method shows that there is often greater complexity submicroscopically, essential to an adequate understanding of a patient's genotype and phenotype.

    Transcatheter transfemoral mitral valve repair using the MitraClip system (Abbott Vascular, USA) is used in high-risk or inoperable patients with severe mitral regurgitation. We report the first-in-human simultaneous transfemoral clipping of the mitral and tricuspid valve completed by occlusion of an atrial septal defect (ASD). The procedure was performed in an 84-year-old patient in October 2015. After effective reduction of mitral and tricuspid regurgitations using the MitraClip system a PFO Occluder (St. Jude Medical, USA) was implanted. Transfemoral simultaneous mitral and tricuspid valve repair using the MitraClip system with ASD occlusion seems to be an effective therapy for high-risk or inoperable patients. PMID:26855642

    We report the case of a large atrial septal aneurysm and a review of the literature. Atrial septal aneurysm is found in 1-8% of normal subjects. Its prevalence is higher among patients with ischemic stroke. Transesophageal echocardiography is an optimal tool for the diagnosis of atrial septal aneurysm. The clinical course may be complicated by arterial embolism, but mechanical complications may also occur, as in this case. Due to the lack of general agreement, treatment options should be discussed on an individual basis for patients with atrial septal aneurysm. PMID:10093663

    Full Text Available Abstract Background Intraseptal hematoma and subsequent myocardial infarction due to accidental contrast agent deposition complicating diagnostic cineventriculography is a previously undescribed complication of angiography. Case presentation A 61 year old man was admitted at intensive care unit because of unstable angina pectoris 1 hour after coronary angiography. Transthoracic contrast echocardiography showed a non-perfused area in the middle of interventricular septum with an increase of thickening up to 26 mm. Review of cineventriculography revealed contrast enhancement in the interventricular septum after contrast medium injection and a dislocation of the pigtail catheter tip. Follow up by echocardiography and MRI showed, that intramural hematoma has resolved after 6 weeks. After 8 weeks successful stent implantation in LAD was performed and after 6 month the patient had a normal LV-function without ischemic signs or septal thickening demonstrated by stressechocardiography. Conclusion A safe and mobile position of the pigtail catheter during ventriculography in the middle of the LV cavity should be ensured to avoid this potentially life-threatening complication. For assessment and absolute measurement of intramural hematoma contrast-enhanced echocardiography is more feasible than MRI and makes interchangeable results.

    Objective To investigate whether transcatheter closure of atrial septal defect makes cardiac troponin I(cTnI) realease in children. Methods Clinical data, laboratory tests, imagings, diagnosis, the information of interventional therapy and postoperative follow-up from 146 children with secundum atrial septal defect who were diagnosed and get treatment of interventional were collected. The median age was(5. 87 ± 3. 48) years( range,2. 25-12. 5) with 87 boys and 59 girls. The device size ranged from 8 to 22 mm. These patients were divided to 2 groups according to the level of cTnI after intervention. The cTnI serum concentrations were examined immediately eafter intervention ,6 hours later,24 hours later and 3 days after intervention. Results The level of cTnI were normal before intervention,and the peak level of cTnI was found at 6 hours after intervention(Z = - 3. 410,P =0. 005) . All of the patients had a normal level of cTnI 3 days after operation ( Z = - 0. 332, P = 0. 74 ) . Univariate analysis showed age, height,device size,size/BSA ratio to be contributing factors for level of cTnI. The device size/body surface area ratio was identified by demonstration positive correlation with cTnI elevation by multivariate logistic regression analysis ( r = 0. 31, P =0. 022 ). Conclusions The transcatheter closure of atrial septal defect in children could lead to reversible increase of cTnI or induce minor myocardial lesion, the extent of which depends on the ratio of device size/ body surface area. Interventional therapy of atrial septal defect is safe and effective for children.%目的 总结并分析儿童继发孔型房间隔缺损患者接受介入封堵治疗前后肌钙蛋白I(cTnI)变化的原因及相关因素,提高临床医师对介入封堵技术治疗儿童房间隔缺损相关适应证及手术风险的了解.方法 收集146例2009年9月至2012年4月在上海儿童医学中心心内科介入封堵的继发孔型房间隔缺损患儿的临床资料、辅

    It is not always easy to observe and screen atrial septal defects (ASD) using echocardiography. In addition, there are no established echocardiographic reference indices for screening patients with ASDs. We retrospectively reviewed our database and recruited 151 isolated ASD patients and 2769 healthy subjects. In total, 307 echocardiographic studies were performed for ASD patients. Surgical repairs were done in 75 of the ASD patients. The ratio of right to left ventricular end-diastolic dimensions (RVD/LVD), which was determined by M-mode echocardiography, was used as an index of RV dilatation. After obtaining age- and body surface area (BSA)-related RVD/LVD nomograms in healthy subjects, we calculated the z-scores of RVD/LVD for all subjects and obtained the optimal cut-off values to differentiate patients with ASD from healthy subjects. The optimal cut-off values were high in neonates and gradually decreased with an increase in the age and BSA, but were almost constant in children aged >4 years or whose BSA was >0.65 m(2). The cut-off values of RVD/LVD for suspected ASD were ≥0.42 in children aged >4 years or those whose BSA was >0.65 m(2). Those for an ASD operation were ≥0.46 in those whose BSA > 0.65 m(2). The RVD/LVD determined by M-mode echocardiography is a useful index to evaluate RV dilatation in patients with ASDs. The RVD/LVD ≥ 0.42 is the warning flag for suspecting ASD in preschool children and that ≥0.46 may be a clinical important sign to determine ASD operation. PMID:26700967

    2013-01-01

    Postoperative extradural hematoma (POEH) is a possible complication after head surgery, often neglected in the literature. In a single surgeon experience we found 13 cases of POEH (0.8%). We distinguished two subtypes: (1) larger hematomas (>40 cc) with typical features and overt clinical picture that always needed evacuation, and (2) smaller hematomas (<40 cc) with insidious clinical onset and different radiological features compared with traumatic and spontaneous extradural hematomas. On the basis of our experience, we propose that clinical picture and radiologic appearance lead the decision between conservative or interventional treatment of type II hematomas.

    Full Text Available Atrial septal defect (ASD is the third most frequent type of congenital heart anomaly, featuring shunting of blood between the two atria. Gene-environment interaction remains to be an acknowledged cause for ASD occurrence. A recent European genome-wide association study (GWAS of congenital heart disease (CHD identified 3 susceptibility SNPs at chromosome 4p16 associated with ASD: rs870142, rs16835979 and rs6824295. A Chinese-GWAS of CHD conducted in the corresponding period did not reveal the 3 susceptibility SNPs, but reported 2 different risk SNPs: rs2474937 and rs1531070. Therefore, we aimed to investigate the associations between the 3 European GWAS-identified susceptibility SNPs and ASD risk in the Han population in southwest China. Additionally, to increase the robustness of our current analysis, we conducted a meta-analysis combining published studies and our current case-control study. We performed association, linkage disequilibrium, and haplotype analysis among the 3 SNPs in 190 ASD cases and 225 age-, sex-, and ethnicity-matched healthy controls. Genotype and allele frequencies among the 3 SNPs showed statistically significant differences between the cases and controls. Our study found that individuals carrying the allele T of rs870142, the allele A of rs16835979, and the allele T of rs6824295 had a respective 50.1% (odds ratio (OR = 1.501, 95% confidence interval (CI = 1.122-2.009, PFDR-BH = 0.018, 48.5% (OR = 1.485, 95%CI = 1.109-1.987, PFDR-BH = 0.012, and 38.6% (OR = 1.386, 95%CI = 1.042-1.844, PFDR-BH = 0.025 increased risk to develop ASD than wild-type allele carriers in our study cohort. In the haplotype analysis, we identified a disease-risk haplotype (TAT (OR = 1.540, 95%CI = 1.030-2.380, PFDR-BH = 0.016. Our meta-analysis also showed that the investigated SNP was associated with ASD risk (combined OR (95%CI = 1.35 (1.24-1.46, P < 0.00001. Our study provides compelling evidence to motivate better understanding of the etiology

    atrial septal defect (ASD. METHODS: Forty patients underwent surgery for correction of MV disease or ASD. Patients were divided into group A (GA (n=20, access by right minithoracotomy and video-assistance; and group B (GB (n=20, access by full MS. Aortic cross-clamp and cardiopulmonary bypass time, intensive care unit (ICU time, hospital stay and morbidity were compared in this prospective study . RESULTS: Fifteen patients were submitted to MV procedures and five to ASD corrections in each group. There were 9 mitral replacements (7 bioprostetic and 2 mechanical and 6 repairs in GA, and 10 (all bioprostetic and five in GB. The mean aortic cross-clamp and cardiopulmonary bypass time, in minutes, were 65.1 ± 29.3 in GA and 50.2 ± 21.4 in GB (p=0.074; and 91.8±35 in GA and 63.7±27.3 in GB ( p=0.008. The mean ICU time, in hours, were 51.7 ± 16.3 in GA and 55.8±17.5 in GB (p=0.45. The in hospital stay, in days, were 5.2 ± 1 in GA and 6.4±1.5 in GB (p=0.009. CONCLUSION: MI access for correction of the MV disease and ASD implicated in a longer cardiopulmonary bypass time for finalization of the main procedure, nevertheless it didn´t affect patient's recuperation. MI treated patients were discharged earlier than sternotomy treated patients.

    The purpose of this study was to investigate the characteristics of childhood acute epidural hematoma and to report our experience in recent years. A series of 35 patients below the age of 15 years treated for acute epidural hematoma at our institution between June 1991 and December 2000 was analyzed in detail. Pediatric epidural hematoma presents both age-related and atypical features when compared with epidural hematoma in adults. In selected cases, prompt surgical evacuation of the hematoma results in an excellent outcome. Outcomes seem to be directly related to the patient's preoperative neurologic status and the presence of associated intracranial lesions.

    Spontaneous muscle hematomas are a common and serious complication of anticoagulant treatment. The incidence of this event has increased along with the rise in the number of patients receiving anticoagulants. Radiological management is both diagnostic and interventional. Computed tomography angiography (CTA) is the main tool for the detection of hemorrhage to obtain a positive, topographic diagnosis and determine the severity. Detection of an active leak of contrast material during the arterial or venous phase is an indication for the use of arterial embolization. In addition, the interventional radiological procedure can be planned with CTA. Arterial embolization of the pedicles that are the source of the bleeding is an effective technique. The rate of technical and clinical success is 90% and 86%, respectively. PMID:26066549

    Hematoma and seroma formation in surgical wounds has negative effects on wound healing and subsequent morbidity to patients. This is of particular pertinence in cosmetic procedures in which the patient has chosen to undergo surgery electively. Over the past several decades there has been considerable interest in the use of ancillary techniques to assist in closing wounds and achieving hemostasis to prevent hematoma and seroma formation. These techniques include application of tissue sealants ...

    2003-01-01

    From January 1991 through December 2001, 600 patients underwent closure of a perimembranous ventricular septal defect through a right atrial approach at our institution. In 122 of these patients, the operation included temporary detachment of a tricuspid valve septal leaflet from the annulus to allow complete visualization of a perimembranous ventricular septal defect The mean age of the patients at surgery was 4.6 years in those who underwent leaflet detachment and 4.7 years in the 478 patients who did not (P > 0.05). Preoperatively, all patients were in sinus rhythm. Echocardiography showed trivial tricuspid regurgitation in 21 of the patients undergoing detachment and in 39 of the non-detachment patients. There was no difference in bypass time or aortic cross-clamp time between the 2 groups. Postoperatively, 3 patients in the non-detachment group had heart block; all other patients were in sinus rhythm. Echocardiograms on the 7th postoperative day showed small residual ventricular septal defects in none of the patients who underwent valve detachment and in 10 of the non-detachment patients; mild tricuspid regurgitation was present in 12 non-detachment patients only; and trivial tricuspid regurgitation was present in 19 patients who underwent valve detachment and in 29 who did not. There was no hospital death in either group. Long-term follow-up showed no progression of tricuspid regurgitation or tricuspid stenosis. All patients remained in sinus rhythm. This study suggests that tricuspid valve detachment is a safe, effective technique that improves exposure for ventricular septal defect repair and does not adversely affect valve competence.

    We present the first report of an intraventricular encapsulated hematoma, mimicking cavernous malformation on imaging and gross lesion appearance. A 47-year-old female on anticoagulation therapy for atrial fibrillation presented with left upper extremity apraxia, neglect, and mild gait imbalance. Her brain CT scan and MRI revealed multilobulated lesions involving the choroid plexus in the atria of both lateral ventricles. The intraoperative appearance was that of encapsulated mass, with blood clots at different stages of liquefaction and organization, all consistent with the gross appearance of a cavernous malformation. However, histopathologic examination demonstrated hematoma with components at different ages, and normal vessel infiltration without any hint of cavernous malformation histology, or underlying neoplasia. Encapsulated hematoma should be considered in the differential diagnosis of hemorrhagic intraventricular masses. PMID:21435884

    @@INTRODUCTION Esophageal hematomas develop from the dissection of the mucosa from the muscular layers of the esophageal wall and represent an uncommon condition affecting all ages[t-3]. Although the most common cause of esophageal hematomas is iatrogenic mechanical injury-induced by prolonged nasogastric intubation, difficult or forceful endoscopic intubation, or the result of variceal injection sclerotherapy- some may be spontaneous,particularly in patients receiving anticoagulants[3-6]. Presenting symptoms most commonly include dysphagia, hematemesis, and sub-sternal or epigastric pain[5,9].

    Objective To evaluate the changes of right ventricular (RV) volume and function by using single beat real-time three dimensional (3-D) echocardiography in patients with atrial septal defect (ASD) before and after percutaneous closure. Methods During the period from July 2011 to Oct. 2013, a total of 45 patients with pure ostium secundum defect were admitted to authors’ hospital to receive percutaneous transcatheter closer. The patients were divided into ASD without pulmonary hypertension (PH) group (group A, n = 28) and ASD with PH group (group B, n = 17). By using 3-D echocardiography and right cardiac catheterization, the right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF), right ventricular cardiac output (RVCO), pulmonary artery systolic pressure (PASP) and the mean pulmonary artery pressure (mPAP) were determined before and after the percutaneous transcatheter closer. The results were compared between the two groups. Results After the treatment a statistically significant reduction in RVEDV, RVESV, RVSV and RVCO were seen in all patients (P 0.05). Pulmonary artery pressure (PAP) decreased significantly in group B after ASD closure when compared with that obtained before Objective To evaluate the changes of right ventricular (RV) volume and function by using single beat real-time three dimensional (3-D) echocardiography in patients with atrial septal defect (ASD) before and after percutaneous closure.

    A 69-year-old man was admitted to our center to undergo catheter ablation of paroxysmal atrial fibrillation refractory to antiarrhythmic drug therapy. This procedure required access to the left atrium through the interatrial septum. During hospitalization, the patient performed routinely pre-procedure transthoracic echocardiography and gadolinium-enhanced cardiac magnetic resonance showing a normal anatomy of both the fossa ovalis and the interatrial septum. Access to the left atrium proved difficult and several unsuccessful attempts to perform the trans-septal puncture were made under both fluoroscopy and intracardiac echocardiography guidance, even with radiofrequency energy delivery. Finally, trans-septal puncture was successfully carried out using a novel nitinol J-shaped "Safe Sept" trans-septal guidewire, designed to cross the interatrial septum through the trans-septal needle thanks to a special sharp tip. Moreover, thanks to its rounded J shape that reduces the risk of atrial perforation, the "Safe Sept" guidewire, when advanced into the left atrium, becomes atraumatic.

    2015-10-01

    The simultaneous occurrence of an intracranial and a spinal subdural hematoma (SDH) is rare. We describe a case of cranial SDH with a simultaneous spinal SDH. An 82-year-old woman visited the emergency room because of drowsiness and not being able to walk 6 weeks after falling down. A neurological examination showed a drowsy mentality. Brain computed tomography showed bilateral chronic SDH with an acute component. The patient underwent an emergency burr-hole trephination and hematoma removal. She exhibited good recovery after the operation. On the fourth postoperative day, she complained of low-back pain radiating to both lower limbs, and subjective weakness of the lower limbs. Spine magnetic resonance imaging revealed a thoracolumbosacral SDH. A follow-up spinal magnetic resonance imaging study that was performed 16 days later showed a significant decrease in the size of the spinal SDH. We discuss the pathogenesis of this simultaneous occurrence of spinal and cranial SDH. PMID:26587198

  19. Is human fracture hematoma inherently angiogenic?

    LENUS (Irish Health Repository)

    Street, J

    2012-02-03

    This study attempts to explain the cellular events characterizing the changes seen in the medullary callus adjacent to the interfragmentary hematoma during the early stages of fracture healing. It also shows that human fracture hematoma contains the angiogenic cytokine vascular endothelial growth factor and has the inherent capability to induce angiogenesis and thus promote revascularization during bone repair. Patients undergoing emergency surgery for isolated bony injury were studied. Raised circulating levels of vascular endothelial growth factor were seen in all injured patients, whereas the fracture hematoma contained significantly higher levels of vascular endothelial growth factor than did plasma from these injured patients. However, incubation of endothelial cells in fracture hematoma supernatant significantly inhibited the in vitro angiogenic parameters of endothelial cell proliferation and microtubule formation. These phenomena are dependent on a local biochemical milieu that does not support cytokinesis. The hematoma potassium concentration is cytotoxic to endothelial cells and osteoblasts. Subcutaneous transplantation of the fracture hematoma into a murine wound model resulted in new blood vessel formation after hematoma resorption. This angiogenic effect is mediated by the significant concentrations of vascular endothelial growth factor found in the hematoma. This study identifies an angiogenic cytokine involved in human fracture healing and shows that fracture hematoma is inherently angiogenic. The differences between the in vitro and in vivo findings may explain the phenomenon of interfragmentary hematoma organization and resorption that precedes fracture revascularization.

    2012-07-01

    Full Text Available We report the case of a patient with an intramural hematoma of the esophagus. This rare condition is more common in elderly women and can be misdiagnosed as cardiovascular or other digestive emergent disease. The classical clinical triad includes chest pain, sudden dysphagia or odynophagia and minor hematemesis. Known precipitating factors are Valsalva maneuver, blunt, direct or iatrogenic injuries, but spontaneous cases have also been described. Chest imaging including computed tomography or magnetic resonance imaging as well as upper gastrointestinal endoscopy are useful tools for diagnosis. The treatment is conservative and the prognosis usually excellent with complete resolution within a few weeks.

    A 4-year-old boy had a 15-mm atrial septal defect repaired percutaneously with use of an Amplatzer Septal Occluder. At age 16 years, he presented with a week's history of fever, chills, dyspnea, fatigue, and malaise. Cultures grew methicillin-sensitive Staphylococcus aureus. A transesophageal echocardiogram showed a 1.25 × 1.5-cm pedunculated mass on the left aspect of the atrial septum just superior to the mitral valve, and a smaller vegetation on the right inferior medial aspect of the septum. At surgery, visual examination of both sides of the septum revealed granulation tissue, the pedunculated mass, the small vegetation, and exposed metal wires that suggested incomplete endothelialization of the occluder. We removed the occluder and patched the septal defect. The patient returned to full activity after 4 months and was asymptomatic 3 years postoperatively. Our report reinforces the need for further investigation into prosthetic device endothelialization, endocarditis prophylaxis, and recommended levels of physical activity in patients whose devices might be incompletely endothelialized. In addition to reporting our patient's case, we review the medical literature on this topic. PMID:27303238

    During ontogeny, the nasal septum exerts a morphogenetic influence on the surrounding facial skeleton. While the influence of the septum is well established in long snouted animal models, its role in human facial growth is less clear. If the septum is a facial growth center in humans, we would predict that deviated septal growth would be associated with facial skeletal asymmetries. Using computed tomographic (CT) scans of n = 55 adult subjects, the purpose of this study was to test whether there is a correlation between septal deviation and facial asymmetries using three-dimensional (3D) geometric morphometric techniques. We calculated deviation as a percentage of septal volume relative to the volume of a modeled non-deviated septum. We then recorded skeletal landmarks representing the nasal, palatal, and lateral facial regions. Landmark data were superimposed using Procrustes analysis. First, we examined the correlation between nasal septal deviation and the overall magnitude of asymmetry. Next, we assessed whether there was a relationship between nasal septal deviation and more localized aspects of asymmetry using multivariate regression analysis. Our results indicate that while there was no correlation between septal deviation and the overall magnitude of asymmetry, septal deviation was associated with asymmetry primarily in the nasal floor and the palatal region. Septal deviation was unassociated with asymmetries in the lateral facial skeleton. Though we did not test the causal relationship between nasal septal deviation and facial asymmetry, our results suggest that the nasal septum may have an influence on patterns of adult facial form.

    2016-07-01

    Ear disease, such as otitis externa, resulting in aggressive head shaking or ear scratching, is the most common cause of the development of aural hematomas in dogs and cats. An underlying immunologic cause has also been proposed to explain cartilage and blood vessel fragility. Numerous options exist for management of aural hematomas, from medical management alone with corticosteroids, to simple hematoma centesis, to surgical intervention. Because this condition is usually secondary to another disease process, regardless of mode of treatment, likelihood of recurrence is low if the underlying condition is managed properly.

    Subcapsular hematoma is an uncommon complication after ureteroscopy and laser lithotripsy. We report on a 38-year-old male with an 8 mm lower pole stone who underwent a left ureteroscopy and laser lithotripsy. The stone was successfully fragmented. Several hours after being discharged home, the patient returned complaining of back pain and hematuria. He was hemodynamically stable. Laboratory exams were normal. A CT study showed a crescent renal subcapsular hematoma surrounding the left kidney. The patient was admitted to the ward for conservative treatment. No additional intervention was necessary. Most subcapsular hematomas tend to resolve spontaneously. PMID:27544565

  15. Occult, massive hematomas following antegrade femoral angioplasty

    International Nuclear Information System (INIS)

    Small groin hematomas are not uncommon after percuatenous antegrade femoral angioplasty (PAFA) and are usually apparent clinically. The authors describe three patients of 235 who underwent PAFA, in whom occult, massive hemorrhage was detected after the procedure. All patients underwent fluoroscopically guided antegrade punctures, with adequate hemostasis achieved after the procedure. CT revealed extraperitoneal hematomas in two patients. One patient required surgical intervention with ligation of the inferior epigastric artery. The authors postulate that these hematomas arose due to inadvertent injury to a branch of the common femoral artery during the puncture. The radiologist should be aware of the chance occurrence of this occult, potentially life-threatening complication

    Study Design Case report. Objective To report the first case of ligamentum flavum hematoma after cervical spine instrumentation 11 years after the index surgery. Methods After performing bilateral C3 and C4 laminectomy, we observed a dark greenish discoloration over the ligamentum flavum, which was opened. We evacuated 15 mL of subacute hematoma. Results The first ligamentum flavum hematoma of the cervical spine that occurred after spinal instrumentation with sublaminar hooks. Conclusion Ligamentum flavum hematoma might happen even after a long delay (in our case, 11 years) from spinal instrumentation (sublaminar hooks). In symptomatic patients, evacuation is the treatment of choice. In cases of instrument adhesion to the surrounding intracanal tissues, removal should be done meticulously after performing a complete release.

    Trephination or trepanation is an intentional surgical procedure performed from the Stone Age. It looks like escaping a black evil from the head. This technique is still used for treatment of chronic subdural hematoma (SDH). Now, we know the origin, pathogenesis and natural history of this lesion. The author try to explore the history of trephination and modern discovery of chronic SDH. The author performed a detailed electronic search of PubMed. By the key word of chronic SDH, 2,593 articles were found without language restriction in May 2015. The author reviewed the fact and way, discovering the present knowledge on the chronic SDH. The first authentic report of chronic SDH was that of Wepfer in 1657. Chronic SDH was regarded as a stroke in 17th century. It was changed as an inflammatory disease in 19th century by Virchow, and became a traumatic lesion in 20th century. However, trauma is not necessary in many cases of chronic SDHs. The more important prerequisite is sufficient potential subdural space, degeneration of the brain. Modifying Virchow's description, chronic SDH is sometimes traumatic, but most often caused by severe degeneration of the brain. From Wepfer's first description, nearly 350 years passed to explore the origin, pathogenesis, and fate of chronic SDH. The nature of the black evil in the head of the Stone Age is uncovering by many authors riding the giant's shoulder. Chronic SDH should be categorized as a degenerative lesion instead of a traumatic lesion. PMID:27169062

    2012-12-01

    Full Text Available Background: Balloon atrial septostomy is an emergent procedure in pediatric cardiology. Nowadays, most patients in need of the procedure have acceptable outcomes after surgical repair. Thus, it is important to perform this procedure as safe as possible. By performing early arterial switch operation and prostaglandin infusion, the rate of balloon atrial septostomy has markedly decreased. However, not all centers performing early arterial switch repairs have abandoned atrial septostomy, even in patients who respond favorably to prostaglandin infusion.Case presentation: In total, eight 1- to 15-day old term neonates admitted in Shahid Rajaee Heart Center in Tehran, Iran from October 2009 to February 2011, with congenital heart diseases were scheduled for balloon atrial septostomy. In six cases the procedure was done exclusively under echocardiographic guidance and in two cases with the help of fluoroscopy. Success was defined as the creation of an atrial septal defect with a diameter equal to or more than 5 mm and ample mobility of its margins.Results: Male sex was predominant (87% and the mean age of the neonates was six days. The diagnosis in all cases was simple transposition of great arteries. The procedure was successful in all patients with any cardiovascular complication.Conclusion: Balloon atrial septostomy is an emergent procedure that can be done safely and effectively under echocardiographic guidance. According to the feasibility of this technique it could be performed fast, safe and effective at bedside, avoiding patient transportation to hemodynamic laboratory or referral center.

    Foda, Hossam M T; Magdy, Emad A

    2006-11-01

    A combined septal perforation repair and rhinoplasty was performed in 80 patients presenting with septal perforations (size 1 to 5 cm) and external nasal deformities. The external rhinoplasty approach was used for all cases and the perforation was repaired using bilateral intranasal mucosal advancement flaps with a connective tissue interposition graft in between. Complete closure of the perforation was achieved in 90% of perforations of size up to 3.5 cm and in only 70% of perforations that were larger than 3.5 cm. Cosmetically, 95% were very satisfied with their aesthetic result. The external rhinoplasty approach proved to be very helpful in the process of septal perforation repair especially in large and posteriorly located perforations and in cases where the caudal septal cartilage was previously resected. Our results show that septal perforation repair can be safely combined with rhinoplasty and that some of the routine rhinoplasty maneuvers, such as medial osteotomies and dorsal lowering, could even facilitate the process of septal perforation repair.

    2005-09-01

    This report describes 2 cases of spontaneous aortic dissecting hematoma in young Border Collie and Border Collie crossbred dogs. Histology was performed in one of the cases involving an unusual splitting of the elastin present within the wall of the aorta, consistent with elastin dysplasia as described in Marfan syndrome in humans. The first case involved a young purebred Border Collie that died suddenly and the second case involved a Border Collie crossbred dog that died after a 1-month history of seizures. Gross lesions included pericardial tamponade with dissection of the ascending aorta in the former case and thoracic cavity hemorrhage, mediastinal hematoma, and aortic dissection in the latter. Histologic lesions in the case of the Border Collie crossbred dog included a dissecting hematoma of the ascending aorta with elastin dysplasia and right axillary arterial intimal proliferation.

  2. Computer tomography of intracranial tumours and hematomas

    International Nuclear Information System (INIS)

    The value of computed tomography (CT) for the diagnosis of intracranial tumors and hematomas was investigated in a retrospective study comprising 220 patients. All C.T.scans are reviewed and described in detail. To assess the diagnostic accuracy, the original interpretation of the C.T.scans was compared with that of conventional neuroradiological and neurophysiological examinations. The aspect on C.T. of the various types of tumors and hematomas proved to vary widely and specific features were seldom seen. This holds particularly for the malignant tumors. Benign tumors such as meningeomas, adenomas and neurilemmomas showed a rather easily identifiable and almost identical picture of the C.T.scan, and diagnosis had to be based mainly on differences in localization. The hematomas, with the exception of the older intracerebral ones, showed the most characteristic C.T.abnormalities. (Auth.)

    2005-01-01

    Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

    Full Text Available OBJECTIVE: Analyze the dromotropic disturbances (vector-electrocardiographic, and the possible anatomic causes, provoked by selective alcohol injection in the septal branch, for percutaneous treatment, of obstructive hypertrophic cardiomyopathy. METHODS: Ten patients with a mean age of 52.7 years underwent percutaneous septal ablation (PTSA from october 1998; all in functional class III/IV. Twelve-lead electrocardiogram was performed prior to and during PTSA, and later electrocardiogram and vectorcardiogram according to Frank's method. The patients were followed up for 32 months. RESULTS: On electrocardiogram (ECG prior to PTSA all patients had sinus rhythm and left atrial enlargement, 8 left ventricular hypertrophy of systolic pattern. On ECG immediately after PTSA, 8 had complete right bundle-branch block; 1 transient total atrioventricular block; 1 alternating transient bundle-branch block either right or hemiblock. On late ECG 8 had complete right bundle-branch block confirmed by vectorcardiogram, type 1 or Grishman. CONCLUSION: Septal fibrosis following alcohol injection caused a predominance of complete right bundle-branch block, different from surgery of myotomy/myectomy.

  5. CT-guided stereotactic evacuation of hypertensive intracerebral hematomas

    International Nuclear Information System (INIS)

    Computerized tomography (CT) is now effective not only for definite diagnosis and location of intracerebral hematomas but also for coordination of the center of a hematoma. CT-guided stereotactic evacuation of hypertensive intracerebral hematoma was performed in 51 cases: 34 of basal ganglionic hematoma with or without ventricular perforation, 11 of subcortical hematoma, 3 of thalamic hematoma and 3 of cerebellar hematoma. Three dimensional CT images or biplane CT images were taken to determine the coordinates of the target point, which was the center of the hematoma. Then, a silicon tube (O.D. 3.5 phi, I.D. 2.1 phi) was inserted into the center of the hematoma through a burr-hole under local anesthesia, and the liquid or solid hematoma was aspirated as completely as possible with a syringe. Urokinase (6,000 I.U./5 ml saline) was administered through this silicon tube every 6 or 12 hours for several days until the hematoma had drained out competely. The silicon tube was taken out when repeated CT scanning revealed no hematoma. The results of clinical follow-ups indicated that this procedure is as good as, or rather better than conventional microsurgery with evacuation of hematoma under direct vision. Moreover this CT-guided stereotactic approach for evacuation of the hematoma has the following advantages: 1) the procedure is simple and safe, 2) operation can be performed under local anesthesia, and 3) the hematoma is drained out completely with the aid of urokinase. This surgery seems indicated as an emergency treatment for high-age or high risk patients and also as a routine surgery for intracerebral hematomas in patients showing no herination signs. (author)

    We report a case of subcorneal hematomas caused by excessive video game play in a 19-year-old man. The hematomas occurred in a setting of thrombocytopenia secondary to induction chemotherapy for acute myeloid leukemia. It was concluded that thrombocytopenia subsequent to prior friction from heavy use of a video game controller allowed for traumatic subcorneal hemorrhage of the hands. Using our case as a springboard, we summarize other reports with video game associated pathologies in the medical literature. Overall, cognizance of the popularity of video games and related pathologies can be an asset for dermatologists who evaluate pediatric patients.

    1981-10-01

    Postoperative epidural hematomas developed far from the operative field are generally recognized as a complication of ventriculo-peritoneal shunt, ventricular drainage or suboccipital craniotomy. It is very rare but may occur after supratentorial craniotomy on the contralateral side. Five such cases are presented with a review of the relevant literature. The mechanism of this complication is not clearly understood. In hydrocephalus, these massive epidural hematomas are probably caused by dura-skull detachment when the brain volume is strikingly reduced by a decompressive procedure. On rare occasions, pins of head rest may detach the dura and cause epidural hematomas. When sudden brain swelling during craniotomy is encountered, attention should be directed not only to intracerebral hemorrhage but also epidural hematoma developed on the contralateral side.

  17. Device Closure of Small Ventricular Septal Defects: When and Why?

    Directory of Open Access Journals (Sweden)

    IB Vijayalakshmi

    2014-10-01

    Full Text Available Ventricular septal defect (VSD accounts for approximately 20-30 % of all forms of congenital heart disease (CHD. They were traditionally closed surgically in the past. The surgery though safe carries the risk of morbidity, complete heart block, wound infection and thoracotomy scar on the chest. On weighing the risk and benefit, the small VSDs were not submitted to surgery in the past. So for many years it has been taught that the small VSDs are to be left alone and surgery is not recommended. Many clinicians believed in spontaneous closure of VSDs. Hence they advised the parents to wait for spontaneous closure till the child is 9 years old. But what if the VSD does not close by 10 years is the question. Are they normal as grown up congenital heart (GUCH. The Jane Somerville GUCH unit showed that spontaneous closure occurred only in 10% between the age of 17 and 45 (mean - 27 years in small VSDs in adults. What is worth noting is about 25% had serious complications: infective endocarditis (11%, progressive aortic regurgitation (5%, age-related symptomatic arrhythmias (8.5% like atrial fibrillation. This means that asymptomatic small VSDs in childhood is not necessarily benign during adult life. This raises the question, when we have a safe non-surgical device closure available to close the small VSDs, should we put the future lives of the young in danger by not giving the benefit of technology to them?

  18. Endoscopic Surgery for Traumatic Acute Subdural Hematoma

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Traumatic acute subdural hematoma (ASDH is generally addressed by craniotomy under general anesthesia. We report a patient whose traumatic ASDH was treated under local anesthesia by one-burr-hole endoscopic surgery. This 87-year-old woman had undergone coil embolization for a ruptured right middle-cerebral artery aneurysm and placement of a ventriculoperitoneal shunt for normal pressure hydrocephalus 5 years earlier. Upon admission, she manifested consciousness disturbance after suffering head trauma and right hemiplegia. Her Glasgow Coma Scale score was 8 (E2V2M4. Computed tomography (CT demonstrated a thick, left-frontotemporal ASDH. Due to her advanced age and poor condition, we performed endoscopic surgery rather than craniotomy to evacuate the ASDH. Under local anesthesia, we made a burr hole in her left forehead and increased its size to 15 mm in diameter. After introducing a transparent sheath into the hematoma cavity with a rigid endoscope, the clot was evacuated with a suction tube. The arterial bleeding point was electrically coagulated. A postoperative CT scan confirmed the reduction of the hematoma. There was neither brain compression nor brain swelling. Her consciousness disturbance and right hemiplegia improved immediately. Endoscopic surgery may represent a viable method to address traumatic intracranial hematomas in some patients.

    The aim of this study was to evaluate atrial electromechanical delay (EMD), P wave dispersion (Pwd), and left atrial (LA) mechanical functions in patients with active acromegaly. Twenty-three patients with active acromegaly and 27 age- and sex-matched controls were included in this study. All atrial electromechanical interval parameters (PA lateral, PA septum, PA tricuspid, interatrial EMD, intra-LA EMD, and intra-right atrial EMD) were measured from mitral lateral annulus, mitral septal annulus, and right ventricular tricuspid annulus by tissue Doppler imaging. LA volumes were measured by the disk method in the apical four-chamber view and were indexed to the body surface area. Mechanical function parameters of LA were calculated. Pwd was performed by 12-lead electrocardiograms. Atrial electromechanical intervals (PA lateral, PA septum, PA tricuspid, interatrial EMD, intra-LA EMD, and intra-right atrial EMD) and Pwd were similar between patients with acromegaly and control subjects (all p > 0.05). LA volumes (maximum, minimum, and presystolic) and LA mechanical functions were not significantly different between the groups (all p > 0.05). Additionally, serum levels of growth hormone and insulin-like growth factor-1 were not correlated with atrial electromechanical parameters and LA mechanical functions. Atrial electrical conduction times were not prolonged and LA mechanical functions were not impaired in patients with active acromegaly compared with controls. And the prevalence of supraventricular arrhythmia risk may not increase in this population.

    Full Text Available In paroxysmal atrial fibrillation usually pulmonary veins isolation is enough, while in persistent and long-standing persistent forms ablation lines in the left atrium are needed. After that post ablational macroreentry tachycardia and focal atrial tachycardia, resistant to antiarrhythmic therapy, occur. Left atrial macroreentry tachycardia are localized perimitrally, around pulmonary veins and septally. There are also roof and posterior wall-associated macroreentry tachycardia. Considering relevance of postablation arrhythmias, we present our case report. A patient had paroxysmal atrial fibrillation. Pulmonary vein isolation was performed. After patient’s radiofrequency pulmonary vein isolation, three-dimensional map of left atrium was made using CARTO XP navigation system. Macroreentry tachycardia around left inferior pulmonary vein was revealed.There were fragmented potentials between left superior and left inferior pulmonary veins. An ablation lineconnecting inferior and superior pulmonary veins was made. After the completion of ablation line sinus rhythmwas restored.

    Full Text Available Introdução: Entre as complicações da septoplastia, o sangramento e o hematoma septal pós-operatório estão entre as mais freqüentes1,2,3. Para prevenir tais problemas, a maioria dos cirurgiões ainda faz uso de tamponamentos nasais ou "splints", que tornam o período pós-operatório imediato extremamente desconfortável para o paciente1,2,4,5,6. Este trabalho se propõe a avaliar a eficácia e a segurança do uso da cola biológica nas septoplastias como profilaxia para essas complicações. Forma de estudo: Clínico prospectivo randomizado. Material e método: Os autores observaram 20 pacientes operados de septoplastia entre janeiro e maio de 2002 pelo Real Instituto de Otorrino e Fono, Recife, nos quais foi utilizado selante de fibrina para colar os folhetos septais. Resultados: Nenhum caso de hematoma septal ou epistaxe pós-operatórios foi observado entre os pacientes estudados. Nenhuma complicação intra ou pós-operatória foi relacionada ao uso da cola. Conclusões: A cola de fibrina mostrou ser uma substância eficaz na prevenção das complicações em questão, assim como bem tolerada pelos tecidos das cavidades nasais. Além disso, o recurso assegurou um pós-operatório muito mais tranqüilo e confortável para os pacientes do que o que se costuma observar em pacientes com tampões nasais ou "splints".Introduction: Among the complications of septoplaty, postoperative septal bleeding and hematoma are some of the most frequent. In order to avoid such problems, most surgeons still use nasal packing and/or splints that make the postoperative period extremely unpleasant. The purpose of this paper is to evaluate the efficacy and safety of fibrin glue in septoplasties for prophylaxis of these complications. Study design: Clinical prospective randomized. Material and method: We observed 20 patients who underwent septoplaties from January to May, 2002, at the Real Instituto de Otorrino e Fono, in whom we used fibrin glue, in order

    Full Text Available Atrial fibrillation (AF is an independent risk factor for stroke. Anticoagulation therapy has a risk of intracerebral hemorrhage. The use of percutaneous left atrial appendage (LAA closure devices is an alternative to anticoagulation therapy. Echocardiography has a leading role in LAA closure procedure in patient selection, during the procedure and during followup. A comprehensive echocardiography study is necessary preprocedural in order to identify all the lobes of the LAA, evaluate the size of the LAA ostium, look for thrombus or spontaneous echo contrast, and evaluate atrial anatomy, including atrial septal defect and patent foramen ovale. Echocardiography is used to identify potential cardiac sources of embolism, such as atrial septal aneurysm, mitral valve disease, and aortic debris. During the LAA occlusion procedure transeosophageal echocardiography provides guidance for the transeptal puncture and monitoring during the release of the closure device. Procedure-related complications can be evaluated and acceptable device release criteria such as proper position and seating of the occluder in the LAA, compression, and stability can be assessed. Postprocedural echocardiography is used for followup to assess the closure of the LAA ostium. This overview paper describes the emerging role of LAA occlusion procedure with transeosophageal echocardiography guidance as an alternative to anticoagulation therapy in patients with AF.

    Full Text Available Percutaneous left atrial appendage (LAA occlusion has emerged as an exciting and effective modality for stroke prophylaxis in patients with non-valvular atrial fibrillation who are deemed too high risk for anticoagulation with warfarin or newer anticoagulants. The Amplatzer devices have been used in LAA occlusion for more than a decade, starting with off label use of an atrial septal occluder device for LAA occlusion. This was followed by introduction of a dedicated Amplatzer cardiac plug (ACP 1 for LAA occlusion, and more recently, the second generation Amulet device, with reported better stability enhancing features, has been introduced. Both these devices are widely used outside the United States, where only the WATCHMAN device has been commonly used. Unlike the WATCHMAN device, where the evidence is continuously building as the data from two pivotal randomized controlled trials are emerging, most of the evidence for ACP devices is from pooled multicenter registry data. In this article, we review the device design, implantation techniques and the most recently published evidence for both the Amplatzer cardiac plug 1 and the newer Amulet device. Our goal is to summarize the most recent literature and discuss the current role of the Amplatzer devices in the exciting and rapidly growing field of percutaneous LAA occlusion.

    Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists. PMID:24553773

  9. CT guided stereotactic evacuation of hypertensive and traumatic intracerebral hematomas

    International Nuclear Information System (INIS)

    Recent advancement of CT system provides not only definite diagnosis and location of intracerebral hematoma but also coordinates of the center of the hematoma. Trials of stereotactic evacuation of the hematoma have been reported by some authors in the cases of subacute or chronic stages of hypertensive intracerebral hemorrhage. In this series, similar surgery has been performed in 33 cases of hypertensive intracerebral hematoma including 22 cases in acute stage, and 2 cases of traumatic hematoma. Clinical outcomes were investigated and the results were considered to be equivalent or rather better in the conventional microsurgery with evacuation of hematoma under direct vision. However, there still remained controversial problems in the cases of threatened herniation signs, because in these cases regular surgery with total evacuation of the hematoma at one time might have been preferable. The benefits of this CT guided stereotactic approach for the evacuation of the hematoma were thought to be as follow: 1) the procedure is simple and safe, 2) operation is readily performed under local anesthesia, and 3) the hematoma was drained out totally by means of urokinase activity. It is our impression that this surgery not only is indicated as emergency treatment for the patients of high-age or in high risk, but also can institute as a routine surgery for the intracerebral hematomas in patients showing no herniation sign.

  10. Benefits of Artcereb on the irrigation of chronic subdural hematoma

    International Nuclear Information System (INIS)

    Chronic subdural hematoma is thought to be an easily treatable disease. However, its recurrence rate is approximately 10%, and such cases require re-operation. We compared the recurrance rate of chronic subdural hematoma with irrigation using either saline or the artificial cerebrospinal fluid Artcereb. We divided the patients into 2 groups. A total of 60 patients in the normal saline group (hematoma, n=58; bilateral hematoma, n=2) underwent irrigation with saline between March 2007 and July 2009. A total of 61 patients in the Artcereb group (hematoma, n=54; bilateral hematoma, n=7) underwent irrigation using Artcereb between August 2009 and May 2011. We performed irrigation via 1 burr hole with 500-1000 ml of either normal saline or Artcereb under local anesthesia and observed until recurrence or disappearance of the hematomas on CT scan. We researched the recurrence rate of the hematomas. Recurrence of the hematomas were observed in 8 cases (13%) in the normal saline group and 5 cases (8.2%) in the Artcereb group. No statistically significant differences were observed. Among those patients who did not receive anticoagulants, the recurrence rate was 6/54 (11%) in the normal saline group and 1/49 (2.0%) in the Artcereb group (p<0.10). Our study showed the possibility that the postoperative recurrence rate of chronic subdural hematoma was lower using Artcereb than saline for irrigation. (author)

    Full Text Available We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    Full Text Available To investigate the performance of hematoma shape, hematoma size, Glasgow coma scale (GCS score, and intracerebral hematoma (ICH score in predicting the 30-day mortality for ICH patients. To examine the influence of the estimation error of hematoma size on the prediction of 30-day mortality.This retrospective study, approved by a local institutional review board with written informed consent waived, recruited 106 patients diagnosed as ICH by non-enhanced computed tomography study. The hemorrhagic shape, hematoma size measured by computer-assisted volumetric analysis (CAVA and estimated by ABC/2 formula, ICH score and GCS score was examined. The predicting performance of 30-day mortality of the aforementioned variables was evaluated. Statistical analysis was performed using Kolmogorov-Smirnov tests, paired t test, nonparametric test, linear regression analysis, and binary logistic regression. The receiver operating characteristics curves were plotted and areas under curve (AUC were calculated for 30-day mortality. A P value less than 0.05 was considered as statistically significant.The overall 30-day mortality rate was 15.1% of ICH patients. The hematoma shape, hematoma size, ICH score, and GCS score all significantly predict the 30-day mortality for ICH patients, with an AUC of 0.692 (P = 0.0018, 0.715 (P = 0.0008 (by ABC/2 to 0.738 (P = 0.0002 (by CAVA, 0.877 (P<0.0001 (by ABC/2 to 0.882 (P<0.0001 (by CAVA, and 0.912 (P<0.0001, respectively.Our study shows that hematoma shape, hematoma size, ICH scores and GCS score all significantly predict the 30-day mortality in an increasing order of AUC. The effect of overestimation of hematoma size by ABC/2 formula in predicting the 30-day mortality could be remedied by using ICH score.

    @@ Retroperitoneal hematoma is an obligatory complication in pelvic ring fracture.1 In most cases, the bleeding originates from venous vessels of the presacral plexus, small arteries and veins from fracture fragments. External fixation of the pelvis can control blood loss by reducing diastasis and dramatically decreasing the volume of the pelvis. But this tamponade effect can not prevent the presence of hematoma in the adjoining retroperitoneal space. It is well known that complication of retroperitoneal hematoma is infection and sepsis.

    Full Text Available Cor-triatriatum is a rare congenital cardiac anomaly. It accounts for 0.1% of congenital heart diseases. Its association with multiple ventricular septal defects (VSD is even rarer. A five-month-old baby was admitted with respiratory distress and failure to thrive. Clinical examination revealed diastolic murmur over mitral area. Chest X-ray showed cardiomegaly. Haematological and biochemical investigations were within normal limits. Electrocardiogram showed left atrial enlargement. 2D echo showed double-chambered left atrium (cor-triatriatum, atrial septal defect (ASD and muscular VSD with moderate pulmonary arterial hypertension. The child was treated with 100% oxygen, diuretics and digoxin and was stabilized medically. We used balanced anaesthetic technique using oxygen, air, isoflurane, fentanyl, midazolam and vecuronium. Patient was operated under cardiopulmonary bypass (CPB with moderate hypothermia. Through right atriotomy abnormal membrane in the left atrium was excised to make one chamber. VSD were closed with Dacron patches and ASD was closed with autologous pericardial patch. Patient tolerated the whole procedure well and was ventilated electively for 12h in the intensive care unit.

    Full Text Available OBJECTIVE: To study mitral valve function in the postoperative period after correction of the partial form of atrioventricular septal defect. METHODS: Fifty patients underwent surgical correction of the partial form of atrioventricular septal defect. Their mean age was 11.8 years and 62% of the patients were males. Preoperative echocardiography showed moderate and severe mitral insufficiency in 44% of the patients. The mitral valve cleft was sutured in 45 (90% patients (group II - GII. Echocardiographies were performed in the early postoperative period, and 6 and 12 months after hospital discharge. RESULTS: The patients who had some type of arrhythmia in the postoperative period had ostium primum atrial septal defect of a larger size (2.74 x 2.08 cm. All 5 patients in group I (GI, who did not undergo closure of the cleft, had a competent mitral valve or mild mitral insufficiency in the preoperative period. One of these patients began to have moderate mitral insufficiency in the postoperative period. On the other hand, in GII, 88.8% and 82.2% of the patients had competent mitral valve or mild mitral insufficiency in the early and late postoperative periods, respectively. CONCLUSION: The mitral valve cleft was repaired in 90% of cases. Echocardiography revealed competent mitral valve or mild mitral insufficiency in 88.8% and 82.2% of GII patients in the early and late postoperative periods, respectively.

    Full Text Available Context: Retroperitoneal hematoma may usually occur as a result of trauma. A life threatening retroperitoneal hematoma is not expected complication of anticoagulation treatment and rarely reported. Low molecular weight heparins (Enoxaparin which are used as effective and safe medicine in the venous thromboemboly treatment have some major complications such as hematomas of different organs. We aim to present a giant spontaneous retroperitoneal hematoma after anticoagulant treatment of pulmonary embolism with enoxaparin. Case Report: A 73-year-old male patient with the diagnosis of pulmonary embolism underwent anticoagulant treatment (enoxaparin. In the second day of admission, the patient had an episode of abdominal and back pain. Abdominal ultrasonography and computerized tomographic scan revealed a giant retroperitoneal hematoma. Enoxaparin treatment was then stopped and the supportive treatment was started. In the following days, hemoglobin levels returned to normal and a control CT revealed regression of hematoma size. Conclusion: The anticoagulant treatment with enoxaparin may lead to severe hematomas. Therefore, the clinical suspicion is required especially in elderly patients and patients with impaired renal function for retroperitoneal hematoma, when they suffer from acute abdominal pain.

    Full Text Available We present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture. Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts. In this paper, we describe the clinical and pathological findings. A brief review of published information on extramedullary hematopoiesis in subdural hematoma and the mechanisms of pathogenesis are also discussed. While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature. Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.

    Full Text Available We describe an interesting case of intramural duodenal hematoma in an otherwise healthy male who presented to emergency room with gradually progressive abdominal pain, nausea, and vomiting. This condition was missed on initial evaluation and patient was discharged from emergency room with diagnosis of acute gastritis. After 3 days, patient came back to emergency room and abdominal imaging studies were conducted which showed that patient had intramural duodenal hematoma associated with gastric outlet obstruction and pancreatitis. Hematoma was the cause of acute pancreatitis as pancreatic enzymes levels were normal at the time of first presentation, but later as the hematoma grew in size, it caused compression of pancreas and subsequent elevation of pancreatic enzymes. We experienced a case of pancreatitis which was caused by intramural duodenal hematoma. This case was missed on initial evaluation. We suggest that physicians should be more vigilant about this condition.

    1994-01-01

    The interhemispheric subdural hematoma is a rare condition. We present a case of interhemispheric subdural hematoma in a patient aged 65 years. A day prior to admission he was struck with a water-pipe on the head. He went to sleep the same evening complaining of a slight headache. At about two o'clock in the morning the headache increased in intensity. By the morning he lost consciousness. On examination by a neurosurgeon the patient was found to be comatose. The physical examination revealed blue eyelids of the left eye, paraplegia of the right leg, paresis of the left leg and arms. Bilateral Babinski's reflex was present, the abdominal reflexes were absent, the tendon and periosteal reflexes were hyperactive. The pupils were equal in size and slowly reactive to light. The patient exhibited symptoms of meningoradicular irritation. An emergency CT scan revealed high-density area in the interhemispheric sulcus extending frontally to parietally. The patients was operated on in an emergency. At operation, extensive rupture of the sagittal sinus was identified. Later the patient died. The presented case was interesting with the extensive rupture of the sagittal sinus and the relatively long lucid interval until clear manifestation of the clinical picture becomes evident.

    Full Text Available Acute posterior fossa subdural hematomas are rare and most of them are trauma-related. Non-traumatic ones have been reported in patients who had idiopathic thrombocytopenic purpura or those who had been receiving anticoagulant therapy. We report on the case of 57-year-old Iranian man who developed sudden severe occipital headache, drowsiness, repeated vomiting, and instability of stance and gait. He was neither hypertensive nor diabetic. No history of head trauma was obtained and he denied illicit drug or alcohol ingestion. A preliminary diagnosis of acute intra-cerebellar hemorrhage was made. His CT brain scan revealed an acute right-sided, extra-axial, crescent-shaped hyperdense area at the posterior fossa. His routine blood tests, platelets count, bleeding time, and coagulation profile were unremarkable. The patient had spontaneous acute infratentorial subdural hematoma. He was treated conservatively and discharged home well after 5 days. Since then, we could not follow-up him, clinically and radiologically because he went back to Iran. Our patient’s presentation, clinical course, and imaging study have called for conservative management, as the overall presentation was relatively benign. Unless the diagnosis is entertained and the CT brain scan is well-interpreted, the diagnosis may easily escape detection.

  1. CT-guided stereotaxic evacuation of cerebellar hematoma

    International Nuclear Information System (INIS)

    Stereotaxic lateral approach for cerebellar hematoma is presented using Leksell's CT-stereotaxic system. All of the procedures are performed in the CT room. Patient's head is turned to contralateral side of the hematoma 30 to 400 with slight flexion of the neck. Stereotaxic apparatus is secured to the head under local anesthesia. Hematoma is confirmed by computerized tomograms. Three dimensional coordinates of the target point (center of the hematoma) are measured from the vertical and diagonal rods of Leksell's system. Linear skin incision 4 cm in length is made on retromastoid area. Burr-hole is put on just lateral position of the target point, usually 5 to 6 cm posterior and 1 cm above from the external auditory meatus. Transverse or sigmoid sinus does not appeared through the burr-hole by this approach. Specially made Dandy's cannula (3.0 mm in diameter, 220 mm in length) is inserted into the target point, and manual evacuation of the hematoma is performed carefully using a syringe. Then Dandy's cannula is replaced by silastic drainage tube (3.5 mm in diameter), and 6,000 Units of Urokinase solved in 2 ml of saline is administered to the hematoma cavity. Dissolved hematoma is aspirated every 24 hours until the most of the hematoma is evacuated. We operated three cases of cerebellar hematoma by this method with favorable results. Advantages of this method are as follows: Operative invasion is minimal; The surgeon can cbeck the residual hematoma and position of the tip of cannula even at operation, if necessary. (author)

  2. CT guided stereotactic evacuation for hypertensive intracerebral hematoma

    International Nuclear Information System (INIS)

    Sixty-one cases of hypertensive intracerebral hematoma were evacuated by CT guided stereotactic method. The operation was performed in the CT room under general anesthesia using the KOMAI-NAKAJIMA STEREOTACTIC DEVICE. This instrument has a micromanipulater that can be used for various kinds of stereotactic procedures. Three dimensional position of the target point (aspiration point of the hematoma) was determined on the film obtained from CT scanning of the patient in the stereotactic system. If the hematoma was small, the target point was enough to be one point at the center of the hematoma, but in case of the large hematoma, several target points were given according to the shape of hematoma. The probe, ordinarily a steel tube 4 mm in outer diameter, was inserted through brain to the target point and the hematoma was aspirated through a silicon tube connected to a vacuum system. Among 61 cases examined, 30 cases of thalamic hemorrhage were operated upon and 36 cases were not operated. They were classified according to the volume of hematoma into 3 groups as follows: A=less than 10 ml, B=11-25 ml, C=more than 25 ml. The operated cases were compared with the non operated cases on the improvement of consciousness in each group. In the A group, the operated patients in the level I recovered more slowly than the non operated patients, but in the level II patients, this was reversed. In the B group, the operated patients improved more quickly except the level I patients. In the C group, almost all of non operated patients died. Thus, this operation was very useful in improving consciousness of level II or III patients independent of hematoma volume. It accelerated the recovery of motor function in the level I. This non inversive technique is considered effective for the removal of deep intracerebral hematoma. (author)

  3. Prospects for conservative treatment of chronic subdural hematomas

    International Nuclear Information System (INIS)

    111In-DTPA was injected into the hematoma cavity before and after hematoma evacuation and irrigation in 12 cases of chronic subdural hematoma with comparatively mild symptoms. The radioactivity in the head was measure with time using a scintillation counter and the attenuation rate was obtained. The value measured hourly were expressed as ratios of the 1st measured value. Because of the properties of 111In-DTPA, this attenuation rate was considered to be the absorption rate of the liqid components of the hematoma. In 8 of the preoperative cases, the average measured values, were 84.8 +- 12.6% after 3 hours, 77.3 +- 12.1% after six hours, 34.5 +- 13.8% after 24 hours and 13.3 +- 13.5% after 48 hours. In six of the postoperative cases, the values were 70.4 +- 14.3% after 3 hours, 47.8 +- 10.8% after 6 hours, 12.4 +- 6.7% after 24 hours and 3.6 +- 2.0% after 48 hours. In a comparison between the two, the postoperative cases showed clearly advanced absorption with a significant difference at a risk factor of 0.1% or less in each case. This is because the osmotic pressure is the same for the liquid in the hematoma, the blood and the cerebrospinal fluid and an explanation based on this alone is difficult; it is neccessary to consider colloid osmotic pressure. When the radioactivities in the liquid in the hematoma, blood and cerebrospinal fluid were measured, the values for the blood were always higher than those for the cerebrospinal fluid and most of the absorption of the hematoma is considered to originate in the vascular bed in the hematoma cavity (sinusoidal channel layer). Therefore, for the conservative treatment of chronic subdural hematomas, it is necessary to consider methods which promote absorption of the hematoma. (J.P.N.)

    2016-01-01

    From 1991 until 2013, 304 patients with intracranial hematomas from aneurysmal rupture were managed surgically in our department, constituting 17 % of all patients with aneurysmal rupture. Of them, 242 patents presented with isolated intracerebral hematomas (in 69 cases associated with significant intraventricular hemorrhage), 50 patients presented with combined intracerebral and subdural hematomas (in 11 cases associated with significant intraventricular hemorrhage), and 12 presented with an isolated subdural hematoma. The surgical procedure consisted of simultaneous clipping of the aneurysm and evacuation of the hematoma in all cases. After surgery, 16 patients (5 %) submitted to an additional decompressive hemicraniectomy, and 66 patients (21 %) submitted to a ventriculo-peritoneal shunt. Clinical outcomes were assessed at discharge and at 6 months, using the modified Rankin Scale (mRS); a favorable outcome (mRS 0-2) was observed in 10 % of the cases at discharge, increasing to 31 % at 6 months; 6-month mortality was 40 %. Applying uni- and multivariate analysis, the following risk factors were associated with a significantly worse outcome: age >60; preoperative Hunt-Hess grades IV-V; pupillary mydriasis (only on univariate); midline shift >10 mm; hematoma volume >30 cc; and the presence of hemocephalus (i.e., packed intraventricular hemorrhage). Based on these results, an aggressive surgical treatment should be adopted for most cases with aneurysmal hematomas, excluding patients with bilateral mydriasis persisting after rescue therapy.

  8. Computed tomographic investigations on intraventricular hematomas

    International Nuclear Information System (INIS)

    This work investigated in 106 patients with intraventricular hematomas all the known factors which can have an influence on prognosis: age, sex, anamnesis of the patients, size, extent and localization of the intracranial bleeding, underlying angiopathy and differences between arterial and venous and spontaneous and traumatic bleedings. It was shown that the state of mind was the deciding prognostic factor, whereby viligance was the cumulative expression of all other investigated influences. A computed tomography (CT) examination is deciding in the question of operative hydrocephalus care. In 13 patients it was further shown, how clearly CT results and brain dissection allowed themselves to be compared. The computed tomographic examination method is best suited to achieve even physiological and more extensive prognostic possibilities. (orig.)

  10. The outcome of the acute subdural hematoma

    International Nuclear Information System (INIS)

    Thirty-five cases of acute subdural hematoma (ASDH) were reviewed and divided into two groups of A and B according to the outcome. The findings of computed tomography (CT) and the time interval between head trauma and surgical intervention were investigated to know the factors that influence the prognosis in ASDH. Group A, 18 patients, had a poor outcome. Fifteen patients out of 18 had the removal of hematoma and decompression craniectomy with 10 deaths, 4 vegetative states and 1 severe disability. Three patients died without surgery. Group B, 17 patients, were treated surgically in the same way as in group A and all patients had a good recovery with 14 making a full recovery and 3 with a moderate disability. Surgical mortality was 31.3% and overall mortality was 37.1%. The features of the CT findings in 18 patients of group A were as follows. Eleven patients had midline shift of more than 15 mm, 9 had subdural high density area of more than 15 mm and 12 patients had bilateral collapse of the lateral ventricles. The charactaristic finding of CT recognized in all patients of group A was disappearance of the ambient cistern. On the contrary, in 17 patients of group B the displacement of the intracranial structure was not so severe as in group A. The midline shift of 14 patients was less than 7.5 mm, the width of subdural high density area of 15 patients was less than 7.5 mm and the ambient cistern was recognized in 12 patients. For 11 patients out of 15 in group A, the operation was performed within 6 hours following the onset of head trauma, however, 9 patients died, one in a vegetative state and one had severe disability postoperatively. Thirteen patients out of 17 in group B were operated on later than 6 hours after the onset of the head trauma, and yet took a good outcome. (J.P.N.)

    Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

    International Nuclear Information System (INIS)

    Complex fractionated atrial electrogram (CFAE) guided ablation is effective in some patients with persistent atrial fibrillation (PeAF), but the pattern of CFAE may be different in the remodeled left atrium (LA). In 100 AF patients (83 males, 55.0±10.6 years old) with AF (51 paroxysmal AF (PAF), 49 PeAF) who underwent catheter ablation, CFAE cycle length (CL) and distribution (NavX 3D map) were compared according to the LA volume (3D-CT) and endocardial voltage (during high right atrial pacing 500-ms (VolPACE) and AF (VolAF; NavX). The mean CFAE-CL was longer (P=0.003) and the % area CFAE was smaller (P=0.006) in patients with LA ≥125 ml than those with PACE AF PACE <1.7 mV than those with ≥1.7 mV (P=0.006). The incidence of septal CFAE was consistently high, regardless of the degree of LA remodeling. In the AF patients with an electroanatomically remodeled LA, the % area of CFAE was smaller and mean CFAE-CL was longer than in those with a less remodeled LA. However, the majority of CFAE are consistently positioned on the septum in the remodeled LA. (author)

    We report a rare case of a meningioma causing acute hematoma. A 67-year-old woman presented with sudden headache. No evidence of trauma was seen. CT demonstrated a subdural hematoma in the convexity of the fronto-temporal lobe. Magnetic resonance imaging showed marked signal heterogeneity in the convexity of the frontal lobe. One week later, the patient underwent hematoma evacuation and tumor resection including the attached dura mater. The histological diagnosis was meningothelial meningioma. The clot was connected directly to the tumor and the origin of the subdural hematoma was identified as the meningioma. Postoperative course was uneventful, and the headache improved. Meningiomas have a relatively benign course but rarely present with hemorrhage. Surgical exploration is the effective and recommended treatment.

    The neuroradiological findings and its outcomes of intracerebral hemorrhage (ICH) were compared between the non-vitamin K antagonist oral anticoagulant (NOAC) therapy and warfarin therapy. In the latest 3 years, 13 cases of nonvalvular atrial fibrillation on NOAC therapy were admitted for ICH. For comparison, 65 age- and gender-comparable patients with ICH on warfarin therapy were recruited. Three NOACs had been prescribed: dabigatran (n = 4), rivaroxaban (n = 2), and apixaban (n = 7). The average ages were 76 ± 9 and 78 ± 8 years in the warfarin (n = 65) and NOAC groups (n = 13), respectively. There was no difference in the clinical features, including the CHADS2 score or HAS-BLED score: 2.62 ± 1.31 versus 2.62 ± 1.33, or 1.09 ± 0.43 versus 1.00 ± 0.41, for the warfarin and NOAC groups, respectively. The volume of ICH warfarin (p = 0.0106). The expansion of hematoma was limited to 7 patients (10.8%) of the warfarin group. A lower hospital mortality and better modified Rankin Scale were observed in the NOAC group than in the warfarin group: 1 (7.7%) versus 27 (41.5%; p = 0.0105) and 3.2 ± 1.4 versus 4.5 ± 1.6 (p = 0.0057), respectively. In conclusion, ICH on NOAC therapy had smaller volume of hematoma with reduced rate of expansion and decreased mortality compared with its occurrence on warfarin. PMID:27289294

    An iliopsoas hematoma can occur either spontaneously or secondary to trauma or bleeding tendency due to hemophilia and anticoagulant therapy. Although liver cirrhosis is commonly associated with coagulopathy, iliopsoas hematoma is very rare. We herein, present a case of bilateral iliopsoas hematoma in a patient with alcoholic cirrhosis, and review the literature on muscle hematoma associated with cirrhosis. A 56-year-old man with alcoholic cirrhosis was admitted in a state of shock with anemia. The cause of anemia could not be detected, and the patient was treated conservatively. The site of bleeding was not detected with either gastroduodenal endoscopy or upper abdominal computed tomography, the latter of which did not include the iliopsoas muscle. He died on the 10th day of admission and bilateral iliopsoas hematomas were found on autopsy. An iron stain was positive in the iliopsoas muscle. Eight cases of muscle hematoma associated with cirrhosis, including the present case, were found in a review of the literature. Four of these cases involved the rectus abdominis muscle, 3 involved the iliopsoas muscle and 1 involved combined muscles. Alcoholic cirrhosis accounted for 75% of the cases. One case (12.5%) was associated with virus-related cirrhosis, and another with combined virus-and alcohol-related cirrhosis. The mortality rate was 75% despite early diagnosis and low risk scores for cirrhosis. Muscle hematoma in patients with cirrhosis isclosely related to alcoholism, and the mortality rate of the condition is extremely high. In conclusion, muscle hematoma should be recognized as an important complication of cirrhosis.

    Full Text Available Left atrial appendage (LAA occlusion is a treatment strategy to prevent blood clot formation in atrial appendage. Although, LAA occlusion usually was done by catheter-based techniques, especially percutaneous trans-luminal mitral commissurotomy (PTMC, it can be done during closed and open mitral valve commissurotomy (CMVC, OMVC and mitral valve replacement (MVR too. Nowadays, PTMC is performed as an optimal management of severe mitral stenosis (MS and many patients currently are treated by PTMC instead of previous surgical methods. One of the most important contraindications of PTMC is presence of clot in LAA. So, each patient who suffers of severe MS is evaluated by Trans-Esophageal Echocardiogram to rule out thrombus in LAA before PTMC. At open heart surgery, replacement of the mitral valve was performed for 49-year-old woman. Also, left atrial appendage occlusion was done during surgery. Immediately after surgery, echocardiography demonstrates an echo imitated the presence of a thrombus in left atrial appendage area, although there was not any evidence of thrombus in pre-pump TEE. We can conclude from this case report that when we suspect of thrombus of left atrial, we should obtain exact history of previous surgery of mitral valve to avoid misdiagnosis clotted LAA, instead of obliterated LAA. Consequently, it can prevent additional evaluations and treatments such as oral anticoagulation and exclusion or postponing surgeries including PTMC.

    Atrial fibrillation increases the risk of stroke, which is a leading cause of death and disability worldwide. The use of oral anticoagulation in patients with atrial fibrillation at moderate or high risk of stroke, estimated by established criteria, improves outcomes. However, to ensure that the benefits exceed the risks of bleeding, appropriate patient selection is essential. Vitamin K antagonism has been the mainstay of treatment; however, newer drugs with novel mechanisms are also available. These novel oral anticoagulants (direct thrombin inhibitors and factor Xa inhibitors) obviate many of warfarin's shortcomings, and they have demonstrated safety and efficacy in large randomized trials of patients with non-valvular atrial fibrillation. However, the management of patients taking warfarin or novel agents remains a clinical challenge. There are several important considerations when selecting anticoagulant therapy for patients with atrial fibrillation. This review will discuss the rationale for anticoagulation in patients with atrial fibrillation; risk stratification for treatment; available agents; the appropriate implementation of these agents; and additional, specific clinical considerations for treatment.

    Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment.

    A 19-year-old male construction worker presented with an injury to his left upper arm after lifting a heavy pipe. He reported an acute onset of sharp pain followed by swelling, warmth, and weakness with elbow flexion. The diagnosis of a distal biceps tendon rupture was made and elective repair was scheduled. Seventy-two hours later, the patient presented with a spontaneous draining wound on his anterior distal humerus. The wound was draining thick purulent material. The patient underwent surgery for irrigation and debridement of his abscess. Nearly 500 cc of hematoma and purulent fluid were evacuated. A large tear of both the biceps and brachialis muscle bellies were found. Cultures were obtained that revealed the infecting organism to be Streptococcus intermedius. Human immunodeficiency virus and hepatitis-C virus testing were negative, and no history, signs, or symptoms of any cause of underlying immunodeficiency were detected. No signs or history of drug use were present. He was discharged home on culture-specific oral antibiotics. At 4-month postoperative follow-up, the patient reported no pain or limitations. He has returned to full duty at his job. Elbow range of motion was measured from 7° to 150° of flexion. Strength of elbow flexion and extension was symmetric to the uninjured side. Pronation and supination of the forearm was symmetric on both sides. He has been released from scheduled follow-up and will be seen again on an as-needed basis. PMID:21053873

    Full Text Available Sébastien Lobet,1,2 Cedric Hermans,1 Catherine Lambert1 1Hemostasis-Thrombosis Unit, Division of Hematology, 2Division of Physical Medicine and Rehabilitation, Cliniques Universitaires Saint-Luc, Brussels, Belgium Abstract: Hemophilia is a hematological disorder characterized by a partial or complete deficiency of clotting factor VIII or IX. Its bleeding complications primarily affect the musculoskeletal system. Hemarthrosis is a major hemophilia-related complication, responsible for a particularly debilitating chronic arthropathy, in the long term. In addition to clotting factor concentrates, usually prescribed by the hematologist, managing acute hemarthrosis and chronic arthropathy requires a close collaboration between the orthopedic surgeon and physiotherapist. This collaboration, comprising a coagulation and musculoskeletal specialist, is key to effectively preventing hemarthrosis, managing acute joint bleeding episodes, assessing joint function, and actively treating chronic arthropathy. This paper reviews, from a practical point of view, the pathophysiology, clinical manifestations, and treatment of hemarthrosis and chronic hemophilia-induced arthropathy for hematologists, orthopedic surgeons, and physiotherapists.

  20. Evaluation of intracerebral hematoma resorption dynamics with computed tomography

    International Nuclear Information System (INIS)

    High mortality and severe grade of disability observed in patients after intracerebral hemorrhage provide efforts to improve diagnostics and therapy of the hemorrhagic cerebral stroke. An aim of this paper was an evaluation of blood resorption dynamics in patients with intracerebral hematoma, performed with computed tomography of the head and an analysis of clinical significance of this process. An examined group included 133 patients with intracerebral hematoma proven by a CT exam. In 97 patients resorption of the hematoma was measured, based on control scans taken on 15th and 30th day on average. Volume of the hemorrhagic foci was measured as well as the width of ventricles and the displacement of medial structures. The mean hematoma volume reached 11,59 ml after 15 days, and 3,16 m after 30 days (average decrease of the volume 0,67 ml/day). There was a significant difference in the rate of resorption between the first (0-15 days) and the second (15-30 days) observation period - 0,78 and 0,62 ml/day respectively. The dynamics of the process was dependent on volume and localization of the hematoma and independent of the grade of displacement and compression of the ventricles. The calculated mean rate of the hematomas resorption enables to schedule control examinations precisely. The significant differences of the dynamics of blood resorption depending on hematomas size and the independence of compression and displacement of ventricular system suggest, that the most important factor in therapeutic decision-making should be a clinical status of the patient.

  1. Exploiting periodicity to extract the atrial activity in atrial arrhythmias

    Science.gov (United States)

    Llinares, Raul; Igual, Jorge

    2011-12-01

    Atrial fibrillation disorders are one of the main arrhythmias of the elderly. The atrial and ventricular activities are decoupled during an atrial fibrillation episode, and very rapid and irregular waves replace the usual atrial P-wave in a normal sinus rhythm electrocardiogram (ECG). The estimation of these wavelets is a must for clinical analysis. We propose a new approach to this problem focused on the quasiperiodicity of these wavelets. Atrial activity is characterized by a main atrial rhythm in the interval 3-12 Hz. It enables us to establish the problem as the separation of the original sources from the instantaneous linear combination of them recorded in the ECG or the extraction of only the atrial component exploiting the quasiperiodic feature of the atrial signal. This methodology implies the previous estimation of such main atrial period. We present two algorithms that separate and extract the atrial rhythm starting from a prior estimation of the main atrial frequency. The first one is an algebraic method based on the maximization of a cost function that measures the periodicity. The other one is an adaptive algorithm that exploits the decorrelation of the atrial and other signals diagonalizing the correlation matrices at multiple lags of the period of atrial activity. The algorithms are applied successfully to synthetic and real data. In simulated ECGs, the average correlation index obtained was 0.811 and 0.847, respectively. In real ECGs, the accuracy of the results was validated using spectral and temporal parameters. The average peak frequency and spectral concentration obtained were 5.550 and 5.554 Hz and 56.3 and 54.4%, respectively, and the kurtosis was 0.266 and 0.695. For validation purposes, we compared the proposed algorithms with established methods, obtaining better results for simulated and real registers.

    Full Text Available Introduction: Atrial conduction time has important hemodynamic effects on ventricular filling and is accepted as a predictor of atrial fibrillation. In this study we assessed atrial conduction time in patients with non ischemic dilated cardiomyopathy (NIDCMP and functional mitral regurgitation (MR and aimed to determine factors predicting atrial conduction time prolongation. Methods: Sixty five patients with non ischemic dilated cardiomyopathy who have moderate to severe MR and 60 control subjects were included in the study. In addition to conventional echocardiographic measures used to asses left ventricle and MR, atrial electromechanical coupling (time interval from the onset of P wave on surface electrocardiogram [ECG] to the beginning of A wave interval with tissue Doppler echocardiography [PA], intra- and interatrial electromechanical delay (intra and inter AEMD were measured. Results: The correlations between inter AEMD and left atrial (LA size, MR volume, isovolumetric relaxation time (IVRT, deceleration time (DT, systolic pulmonary artery pressure (PAPs, E/A ratio and E/e’ were very poor. Similarly, intra AEMD was not correlated to LA size , MR volume, IVRT, DT, PAPs, E/A ratio and E/e’. However, both inter AEMD and intra AEMD had good correlation with left ventricular mass index, tenting area (TA, tenting distance (TD, coaptation septal distance (CSD, sphericity index (SI. Conclusion: Prolongation of inter and intra AEMDs were found to be well correlated with parameters reflecting left ventricular and mitral annular remodeling.

    Background: In much of the Western hemisphere, mortality from traumatic acute extradural hematomas (AEDH) has been drastically brought down toward 0%. This is still not the case however in most developing countries. Case Description: This report represents a tragi-comic tale of two cases of traumatic AEDH managed by an academic neurosurgeon in a neurosurgically ill-resourced private health facility during a nationwide industrial strike action preventing clinical-surgical care in the principal author's University Teaching Hospital. A young man presented with altered consciousness, Glasgow Coma Score (GCS) 14/15, following a road accident. The cranial computed tomography (CT) scan was obtained only 9 h after its request, long after the man had actually deteriorated to GCS 7/15 with pupillary changes. The neurosurgeon, summoned from the nearby University Teaching Hospital for the operative care of this man, arrived on-site and was about moving the patient into the operative room when he took the final breaths and died, all within 2 h of the belated neuroimaging. This scenario repeated itself in the same health facility just 24 h later with another young man who presented GCS 7/15 and another identical CT evidence of traumatic AEDH. With more financially able relations, the diagnostic/surgical care of this second patient was much more prompt. He made a very brisk recovery from neurosurgical operative intervention. He is alive and well, 5-month postoperative. Conclusions: In most low-resourced health systems of the developing countries, a significant proportion of potentially salvageable cases of AEDH still perish from this disease condition.

One potential explanation for these deleterious effects of glucose in the septum is that there are highe...

  10. Electrophysiologic and anatomical characteristics of the right atrial posterior wall in patients with and without atrial flutter. Analysis by intracardiac echocardiography

    International Nuclear Information System (INIS)

    The posterior right atrial transverse conduction capability during typical atrial flutter (AFL) is well known, but its relationship to the anatomical characteristics remains controversial. Thirty-four AFL and 16 controls underwent intracardiac echocardiography after placement of a 20-polar catheter at the posterior block site during AFL or pacing. In 31 patients, the effective refractory period (ERP) at the block site was determined as the longest coupling interval that resulted in double potentials during extrastimuli from the mid-septal (SW) and free (FW) walls. The block site was located 3.0-29.0 mm posterior to the crista terminalis (CT) in each AFL and control patient. The CT area indexed to the body surface area was larger in AFL patients than in control patients (16.4±6.5 mm2/m2 vs 11.3±6.4 mm2/m2, p=0.01), and was positively correlated to age (r=0.34, p=0.02). The ERP was longer in the AFL patients than in controls (SW: median value 600 [270-725] ms vs 220 [200-253] ms; FW: 280 [230-675] ms vs 215 [188-260] ms, p<0.05 for each). A functional block line was located on the septal side of the CT in all patients. A limited conduction capability and age-related CT enlargement might have important implications for the pathogenesis in AFL. (author)

    Full Text Available Abstract Premature closure or restriction of foramen ovale (PCFO is a rare congenital anomaly that can lead to a wide spectrum of cardiac malformations. This spectrum of secondary malformations appears to depend on the gestational timing of closure of the foramen ovale and to the degree of restriction. Earlier in the gestation, closure of the foramen has been associated with severe hypoplasia of the left ventricle whereas later closure has been associated with right heart failure and rarely with the formation of an aneurysm of the atrial septum. We describe the case of a 1 day old infant in whom PCFO resulted in severe right heart failure in addition to the formation of a giant atrial septal aneurysm.

    Postoperative chronic subdural hematoma (CSH) following craniotomy developed in only four of 372 patients undergoing craniotomy for aneurysm surgery (1 patient) and brain tumor surgery (3 patients) between April, 1991 and November, 1993, an incidence of only 1.1%. There were three males and one female, aged from 32 to 66 years (mean 56 yrs). The period between craniotomy and development of CSH ranged from 3 to 5 months (mean 4.3 mos). Postoperative hematomas were located on the operative sides in three patients and the contralateral side in the other. Early postoperative computed tomographic scans found subdural fluid collection in all patients. Magnetic resonance images showed linear meningeal enhancement in all patients. Postoperative CSH may be caused by mixture of blood in subdural cerebrospinal fluid collection which persists due to reduced brain elasticity and wide subarachnoid membrane opening resulting in neomembrane formation and finally development of hematoma.

    This review discusses atrial fibrillation according to the guidelines of Brazilian Society of Cardiac Arrhythmias and the Brazilian Cardiogeriatrics Guidelines. We stress the thromboembolic burden of atrial fibrillation and discuss how to prevent it as well as the best way to conduct cases of atrial fibrillatios in the elderly, reverting the arrhythmia to sinus rhythm, or the option of heart rate control. The new methods to treat atrial fibrillation, such as radiofrequency ablation, new oral direct thrombin inhibitors and Xa factor inhibitors, as well as new antiarrhythmic drugs, are depicted.

    Full Text Available Duodenal intramural hematoma (DIH usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

    Although bone infarction is a common feature in sickle cell disease, the involvement of the orbit is an unusual complication. Intracranial bleeding is another uncommon and serious complication. Few cases of orbital infarction alone have been reported. We report imaging findings (CT, bone scan, MRI) in a 16-year-old boy with sickle cell disease with orbital infarction and epidural hematoma. The precise cause of epidural hematoma is not well known, but it is probably related to vaso-occlusive episodes and the tearing of small vessels. (orig.)

    A spontaneous retropharyngeal hematoma is a rare condition with a difficult diagnostic. This disease may rapidly progress to an airway obstruction. The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed.

    Epidural angiolipomas are uncommon benign tumors of the spine. Their clinical presentation is usually a progressive spinal cord compression. We report the case of a 22-year-old patient who presented with an acute paraparesis and a spontaneous epidural hematoma, which revealed a epidural angiolipoma which extended from C7 to T3. The patient underwent a C7-T3 laminectomy, in emergency, with evacuation of the hematoma and extradural complete resection of a fibrous epidural tumor bleeding. The postoperative course was favorable with regression of neurological symptoms. Epidural angiolipomas can be revealed by spontaneous intratumoral hemorrhage without traumatism. The standard treatment is total removal by surgery. PMID:26597606

    Full Text Available Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones peridurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica.

    The importance of atrial fibrillation (AF) as a cause of mortality and morbidity has prompted research on its pathogenesis and treatment. Recognition of AF risk factors is essential to prevent it and reduce the risk of death. Hyperuricemia has been widely accepted to be associated with the incidence of paroxysmal or persistent AF, as well as to the risk of AF in post cardiovascular surgery patients. The possible explanations for this association have been based on their relation with either oxidative stress or inflammation. To investigate the link between hyperuricemia and AF, it is necessary to refer to hyperuricemia-induced atrial remodeling. So far, both ionic channel and structural remodeling caused by hyperuricemia might be plausible explanations for the occurrence of AF. Inhibition of xanthine oxidase and nicotinamide adenine dinucleotide phosphate (NADPH)-oxidase, or the use of antioxidants, along with serum uric acid (SUA) level reduction to prevent inflammation, might be useful. Uric acid transporters (UATs) play a key role in the regulation of intracellular uric acid concentration. Intracellular rather than serum uric acid level is considered more important for the pathogenesis of AF. Identification of UATs expressed in cells is thus important, and targeting UATs might become a potential strategy to reduce the risk of hyperuricemia-induced atrial fibrillation. PMID:27396561

    Full Text Available Atrial fibrillation (AF is a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation. On the ECG fibrillatory (f waves (rapid oscillations with variable amplitude, shape and timing replace normal P waves. Ventricular response becomes irregular and rapid depending of the intrinsic electrophysiological properties of the AV node1 and the balance between vagal and sympathetic tone1. The presence of an irregularly pulse is a clinical sign that can be quickly and reliably identified in any healthcare situation and, indicates AF with a high sensitivity and specificity (95% and 75%, respectively. If the irregularity last for more than 20 seconds the specificity reaches 98% 2-4. Identification of AF can be done by using manual pulse palpation in those presenting with a variety of symptoms. It is desirable to check the blood pressure and pulse in all patients who present with breathlessness, dyspnea, palpitations, syncope, dizziness or chest discomfort. Furthermore, many patients presenting with an acute stroke are found to be in AF albeit asymptomatic with respect to non-neurologic complaints. The finding of a sustained irregular wide QRS complex tachycardia may be suspicious of AF conducted with bundle brunch aberrancy or over an accessory pathway, and in patients with A-V sequential pacemakers can reflect an inadequate configuration with ventricular tracking of sensed atrial activity.

    Full Text Available Introduction: Lower end of humerus shows olecranon and coronoid fossae separated by a thin bony septum, sometimes it may deficient and shows foramen which communicates both the fossae called Septal aperture, which is commonly referred as supratrochlear foramen (STF. Materials & Methods: We have studied 260 humeri (126 right side and 134 left side, measurements were taken by using vernier caliper, translucency septum was observed by keeping the lower end of humerus against the x-ray lobby. Results: A clear cut STF was observed in 19.2% bones, translucency septum was observed in 99 (91.6% humeri on the right side and 95 (93.1% humeri on the left sides respectively (Table – 1. Clinical significance: The presence of STF is always associated with the narrow medullary canal at the lower end of humerus, Supracondylar fracture of humerus is most common in paediatric age group, medullary nailing is done to treat the fractures in those cases the knowledge about the STF is very important for treating the fractures. It has been observed in x-ray of lower end of the humerus the STF is comparatively radiolucent, it is commonly seen as a type of ‘pseudolesions’ in an x-ray of the lower end of humerus and it may mistake for an osteolytic or cystic lesions. Conclusion: The present study can add data into anthropology and anatomy text books regarding STF and it gives knowledge of understanding anatomical variation of distal end of the humerus, which is significant for anthropologists, orthopaedic surgeons and radiologists in habitual clinical practice.

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    Background Learning embryology remains difficult, since it requires understanding of many complex phenomena. The temporal evolution of developmental events has classically been illustrated using cartoons, which create difficulty in linking spatial and temporal aspects, such correlation being the keystone of descriptive embryology. Methods We synthesized the bibliographic data from recent studies of atrial septal development. On the basis of this synthesis, consensus on the stages of atrial septation as seen in the human heart has been reached by a group of experts in cardiac embryology and paediatric cardiology. This has permitted the preparation of three-dimensional (3-D) computer graphic objects for the anatomical components involved in the different stages of normal human atrial septation. Results We have provided a virtual guide to the process of normal atrial septation, the animation providing an appreciation of the temporal and morphologic events necessary to separate the systemic and pulmonary venous returns. Conclusion We have shown that our animations of normal human atrial septation increase significantly the teaching of the complex developmental processes involved, and provide a new dynamic for the process of learning.

    1991-02-01

    Traumatic acute subdural hematoma remains one of the most lethal of all head injuries. Since 1981, it has been strongly held that the critical factor in overall outcome from acute subdural hematoma is timing of operative intervention for clot removal; those operated on within 4 hours of injury may have mortality rates as low as 30% with functional survival rates as high as 65%. Data were reviewed for 1150 severely head-injured patients (Glasgow Coma Scale (GCS) scores 3 to 7) treated at a Level 1 trauma center between 1982 and 1987; 101 of these patients had acute subdural hematoma. Standard treatment protocol included aggressive prehospital resuscitation measures, rapid operative intervention, and aggressive postoperative control of intracranial pressure (ICP). The overall mortality rate was 66%, and 19% had functional recovery. The following variables statistically correlated (p less than 0.05) with outcome; motorcycle accident as a mechanism of injury, age over 65 years, admission GCS score of 3 or 4, and postoperative ICP greater than 45 mm Hg. The time from injury to operative evacuation of the acute subdural hematoma in regard to outcome morbidity and mortality was not statistically significant even when examined at hourly intervals although there were trends indicating that earlier surgery improved outcome. The findings of this study support the pathophysiological evidence that, in acute subdural hematoma, the extent of primary underlying brain injury is more important than the subdural clot itself in dictating outcome; therefore, the ability to control ICP is more critical to outcome than the absolute timing of subdural blood removal.

    2015-01-01

    Full Text Available Left atrial (LA volumes are known to be increased in hypertrophic cardiomyopathy (HCM and are a predictor of adverse outcome. In addition, LA function is impaired and is presumed to be due to left ventricular (LV diastolic dysfunction as a result of hypertrophy and myocardial fibrosis. In the current study, we assess the incremental effect of outflow tract obstruction (and concomitant mitral regurgitation on LA function as assessed by LA strain. Patients with HCM (50 obstructive, 50 nonobstructive were compared to 50 normal controls. A subset of obstructive patients who had undergone septal myectomy was also studied. Utilising feature-tracking software applied to cardiovascular magnetic resonance images, LA volumes and functional parameters were calculated. LA volumes were significantly elevated and LA ejection fraction and strain were significantly reduced in patients with HCM compared with controls and were significantly more affected in patients with obstruction. LA volumes and function were significantly improved after septal myectomy. LVOT obstruction and mitral regurgitation appear to further impair LA mechanics. Septal myectomy results in a significant reduction in LA volumes, paralleled by an improvement in function.

    The aim of the present study was to determine whether left atrial size--a likely indicator of atrial stretching--correlates with the plasma concentration of atrial natriuretic peptide and whether this relation is different in patients in sinus rhythm and in those with atrial fibrillation. Arterial plasma concentrations of immunoreactive atrial natriuretic peptide (ir-ANP), adrenaline, noradrenaline, aldosterone, and vasopressin were measured in 13 patients in sinus rhythm without apparent hea...

    Full Text Available With expected success rates in excess of 80% for achieving long term arrhythmia control, catheter based ablation has become a popular treatment strategy in the management of patients with atrial fibrillation (AF. However, the success of AF ablation has been tempered by the occurrence of post procedure left atrial tachycardias and / or flutters, which can be seen in up to 30% of the patients. These arrhythmias are perpetuated either due to abnormalities of impulse formation (abnormal automaticity / triggered activity, or abnormalities of impulse conduction (micro / macroreentry. Regardless of the underlying mechanism, these tachycardias manifest distinct “P” or flutter waves on the surface ECG, recognition of which may facilitate their characterization / localization. However, because of the frequent overlap in the morphology of P waves, intracardiac mapping is often the only way to distinguish them apart. This is accomplished using a combination of activation, entrainment and electroanatomic mapping techniques. Tachycardias resulting from abnormalities of impulse formation and / or microreentry are characteristically focal and usually confined in and around pulmonary vein (PV segments which have reconnected (septal aspect of right PVs and anterior aspect of left PVs. In contrast, macroreentrant tachycardias manifest a large circuit dimension involving zone(s of slow conduction. These are most commonly seen to occur around the mitral valve but can develop in any part of the left atrium where “gaps” across prior ablation lesion sets create altered conduction. Successful ablation of focal tachycardias is usually accomplished by isolating the reconnected PV segment(s. In case of macroreentrant arrhythmias however, a more extensive ablation approach is typically required in order to achieve conduction block across isthmus of the circuit. Using these strategies, the majority of left atrial tachycardias occurring post AF ablation can be

    Full Text Available Catheters able to measure the force and vector of contact between the catheter tip and myocardium are now available. Pre-clinical work has established that the degree of contact between the radiofrequency ablation catheter and myocardium correlates with the size of the delivered lesion. Excess contact is associated with steam pops and perforation. Catheter contact varies within the left atrium secondary to factors including respiration, location, atrial rhythm and the trans-septal catheter delivery technology used. Compared with procedures performed without contact force (CF-sensing, the use of this technology has, in some studies, been found to improve complication rates, procedure and fluoroscopy times, and success rates. However, for each of these parameters there are also studies suggesting a lack of difference from the availability of CF data. Nevertheless, CF-sensing technology has been adopted as a standard of care in many institutions. It is likely that use of CF-sensing technology will allow for the optimization of each individual radiofrequency application to maximize efficacy and procedural safety. Recent work has attempted to define what these optimal targets should be, and approaches to do this include assessing for sites of pulmonary vein reconnection after ablation, or comparing the impedance response to ablation. Based on such work, it is apparent that factors including mean CF, force time integral (the area under the force-time curve and contact stability are important determinants of ablation efficacy. Multicenter prospective randomized data are lacking in this field and required to define the CF parameters required to produce optimal ablation.

    Full Text Available Introduction Ventricular septal defect (VSD is an opening in the interventricular septum. 30-50% of patients with congenital heart disease have VSD. Objective The aim of the study was to determine the dependence of the left ventricular diastolic dimension (LVD, left ventricular systolic dimension (LVS, shortening fraction (SF, left atrium (LA, pulmonary artery truncus (TPA on the body surface and compare their values among experimental, control and a group of healthy children. Values of maximal systolic gradient pressure (Pvsd of VSD were compared with children from one experimental and control group. Method Children were divided into three groups: experimental (32 children with VSD that were to go to surgery, control (20 children with VSD who did not require surgery and 40 healthy children. Measurements of LVD, LVS, SF, LA, TPA were performed in accordance to recommendations of the American Echocardiographic Association. The value of Pvsd was calculated from the maximal flow velocity (V in VSD using the following formula: Pvsd=4xVІ (mm Hg. Results For children from the experimental group, the relationship between the body surface and the variability of the LVD was explained with 56.85%, LVS with 66.15%, SF with 4.9%, TPA with 58.92%. For children from the control group, the relationship between the body surface and the variability of LVD was explained with 88.8%, LVS with 72.5%, SF with 0.42%, PA with 58.92%. For healthy children, the relationship between the body surface and the variabilitiy of the LVD was explained with 88.8%, LVS with 88.78%, SF with 5.25% and PA with 84.75%. There was a significant statistical difference between average values of Pvsd in the experimental and control group (p<0.02. Conclusion The presence of the large VSD has an influence on the enlargement of LVD, LVS, SF, TPA. The enlargement of the size of the pulmonary artery depends on the presence of VSD and there is a direct variation in the magnitude of the shunt

    Objective To evaluate the short-term effect of low atrial septum pacing and different pacing frequency to prevent atrial fibrillation in patients with sick sinus syndrome . The electrophysiological mechanism would be ana-lyzed. Methods Thirty eight sick sinus syndrome patients were randomly divided to right atrial appendage pacing group and low atrial septum pacing group. The conduction time from P wave to left atrial and left atrioventricular in-terval was measured at different atrial pacing frequency. The effects of different atrial pacing frequency on interatrial conduction time were analyzed. The occurrence of atrial fibrillation was compared within an average one year follow-up period. Results ①There were no differences in basic information before treatment between the two groups. ②There were no complication, pacing and sensing dysfunction between the two groups.③The occurrence of atrial fi-brillation in low atrial septal group was lower than that in right atrial appendage pacing group. Similarly, the con-duction time from P wave to left atrial was shorter and left atrioventricular conduction time was longer in low atrial septal group. The difference was statistically significant.④ Left atrioventricular interval was longer in high pacing frequency(80 bpm) compared to low pacing frequency(60 bpm) between the two groups. The difference was statis-tically significant. Conclusion In sick sinus syndrome patients, the occurrence of atrial fibrillation is lower on low-er atrial septal group. Increasing atrial pacing percentage may be enhanced the effect. The mechanism may be asso-ciated with shortened interatrial conduction and extended left atrioventricular interval, which improves interatrial and left atrioventricular synchrony eventually.%目的:探讨低位房间隔起搏及不同起搏频率对病态窦房结综合征患者术后房颤的短期影响,分析其电生理机制。方法38例病态窦房结综合征患者随机将心房电极植入

    Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

  14. Solitary pulmonary nodule by pulmonary hematoma under warfarin therapy

    International Nuclear Information System (INIS)

    Pulmonary hematoma is a rare cause of a pulmonary nodule. Mostly it results from penetrating or blunt chest injuries. The case of a patient is reported, whose chest X-ray showed a pulmonary nodule suspected of malignancy. This patient was maintained permanently on anticoagulants (warfarin derivates) after cardiac valve replacement with a prosthesis. A definite diagnosis could not be established by non-invasive methods. A needle biopsy of the lung was impracticable because of the location of the pulmonary lesion; an exploratory thoracotomy could not be carried out due to a general indication of nonoperability. Control examinations showed that the pulmonary nodule had vanished completely within four months. In consideration of the patient's clinical situation it can be concluded that the pulmonary lesion was caused by a hematoma of the lung. (orig.)

  15. MR imaging evaluation of subdural hematomas in child abuse

    International Nuclear Information System (INIS)

    MR imaging is the most accurate modality for determining the presence, number, and aging of subdural hematomas. Based on seven patients studied with CT and MR imaging, MR imaging should be the gold standard in child abuse evaluations. Since the history of child abuse is often ambiguous, MR imaging can assist in dating when the injury occurred. MR imaging in two perpendicular planes is needed, with one plane having both T1- and T2-weighted sequences. Chronic subdural hematomas on CT often have the same density as cerebrospinal fluid and may be misdiagnosed as atrophy or unrecognized. Therefore, the child may be returned into a dangerous situation and subjected to recurrent episodes of battering

  16. Analysis of infantile subdural hematoma caused by abuse

    International Nuclear Information System (INIS)

    We report infantile subdural hematoma caused by abuse. Between January 2006 and December 2009, 10 cases of definite and highly suspicious abusive subdural hematoma in infants were treated at Nara Medical University Hospital. The mean age was 5.4 months. On CT examination, severe cerebral swelling was seen in 8 (80%) and wide spreading cerebral ischemia and atrophy in 9 (90%). Retinal hemorrhage was commonly seen in this series (90%). Subdural drainage and/or subdural-peritoneal shunt surgeries were performed in 6 cases, and intensive combined therapy of mild hypothermia and barbiturate was adapted in 7 cases. Favorable outcome was achieved in only 3 cases. In spite of aggressive treatment, clinical outcome are still bad. In our series, assailants were predominantly not father but mother. There were various and complex factors for child abuse. Cautious insight and suspicion are necessary to detect abusive injuries in infants. It is very important to endeavor to prevent recurrences of abusive injuries. (author)

    OBJECTIVES: This study was conducted to evaluate follow-up results in patients with hypertrophic obstructive cardiomyopathy (HOCM) who underwent either percutaneous transluminal septal myocardial ablation (PTSMA) or septal myectomy. BACKGROUND: Controversy exists with regard to these two forms of treatment for patients with HOCM. METHODS: Of 51 patients with HOCM treated, 25 were treated by PTSMA and 26 patients via myectomy. Two-dimensional echocardiograms were performed before both procedures, immediately afterwards and at a three-month follow-up. The New York Heart Association (NYHA) functional class was obtained before the procedures and at follow-up. RESULTS: Interventricular septal thickness was significantly reduced at follow-up in both groups (2.3 +/- 0.4 cm vs. 1.9 +/- 0.4 cm for septal ablation and 2.4 +/- 0.6 cm vs. 1.7 +/- 0.2 cm for myectomy, both p Doppler, the resting pressure gradient (PG) across the left ventricular outflow tract (LVOT) significantly decreased immediately after the procedures in both groups (64 +/- 39 mm Hg vs. 28 +/- 29 mm Hg for PTSMA, 62 +/- 43 mm Hg vs. 7 +/- 7 mm Hg for myectomy, both p treatment for LVOT obstruction.

    Acute subdural hematomas (ASDHs) are rarely reported in the literature. In general, it is due to head trauma, but if the traumatic event is very mild, it is inadequate to explain the ASDH occurrence. Risk factors for the development of spontaneous ASDH include hypertension, vascular abnormalities and deficit of coagulation. We present two cases of ASDH in patients with the coagulation deficit and review of the literature to understand the coagulation factors role and platelet role in the management of ASDHs.

    2008-07-01

    Full Text Available Atrial fibrillation is common in heart failure patients and is associated with increased mortality. Pharmacologic trials have not shown any survival benefit for a rhythm control over a rate control strategy. It has been suggested that sinus rhythm is associated with a survival benefit, but that the risks of anti-arrhythmic drug treatment and poor efficacy offset the beneficial effect. Catheter ablation for atrial fibrillation can establish sinus rhythm without the risks of anti-arrhythmic drug therapy. Data from randomized trials demonstrating a survival benefit for patients undergoing an ablation procedure for atrial fibrillation are still lacking. Ablation of the AV junction and permanent pacing remain a treatment alternative in otherwise refractory cases. Placement of a biventricular system may prevent or reduce negative consequences of chronic right ventricular pacing. Current objectives and options for treatment of atrial fibrillation in heart failure patients are reviewed.

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking.

    In recent years in the Department of Neurotraumatology in Cracow it has been noticed the frequent connection between appearance of chronic subdural hematoma (CSDH) and treatment by anticoagulant medications. The aim of this study is to draw attention to the problem of insufficient control of anticoagulants consumption, especially by patients treated for cardiovascular system diseases that increases the risk of bleeding and CSDH development. The paper is based on data from questionnaires that was sent to patients with CSDH, cured in the Department of Neurotraumatology form 2004 to 2005. Analyzed was the group of 51 patients with chronic subdural hematoma; 37 individuals (72.5%) confirmed taking acetylsalicylic acid in the period of 3 months before admission to the Department, 9 (17.6%) patients answered that they were taking low-molecular weight heparin. One patient (1.9%) was taking chronically derivative of cumarin. The authors would inform that anticoagulant treatment might favour increase of chronic subdural hematoma incidence. It's especially important, because the average life expectancy has been prolonged in Poland and there are more people taking acetylsalicylic acid. This can be an epidemiological problem in future.

    2016-01-01

    Background: Tentorial hematoma is frequently seen in traumatic brain injury (TBI) patients, especially in motorized two-wheeler riders following head injury. However its relevance and prognostic significance are not known. Objective: To evaluate patients of TBI with tentorial hematoma using a simple grading system and attempt to correlate this grading with factors like helmet use and neurological outcome. Materials and Methods: This prospective study over a 1-year period included patients with TBI who had tentorial hematoma in the initial plain head. Patients were divided into three grades based on the initial CT findings: Grade I: Isolated tentorial hematoma, grade II: tentorial hematoma with midline shift but open cisterns and grade III: Tentorial hematoma with effaced cisterns. Clinical and radiological records of patients including admission GCS and GOS at discharge were assessed in all cases. Observations: A total of 1786 patients of TBI were admitted during the study period. Of these, 106 (5.9%) patients had tentorial hematoma. 84.9% (n = 90) were male and 15.1% (n = 16) were female with the mean age being 36.5 years (range 2-66 years). The mean admission GCS was 13, 11 and 8 in patients with grade I, II and III tentorial hematoma respectively. 43.4% (n = 46) of the patients had grade I, 32.1% (n = 34) had grade II and 24.5% (n = 26) patients had grade III tentorial hematoma. Seventy-one patients (84.5%) were riding motorized two wheelers with 63 (89%) wearing helmets. The majority of the patients wearing helmets (58.8%) had grade I hematoma with 35% (n = 22) having grade II hematoma and only 6.3% (n = 4) having grade III hematoma. Overall, there were 20 deaths. 50% (n = 10) of the deaths were in patients with grade III hematoma and 40% (n = 8) of the deaths were in patients with grade II hematoma. There were two (10%) deaths in patients with grade I hematoma (both unrelated to head injury). The mean GOS at the time of discharge was 5, 4.1 and 2.2 in patients

    Background We hypothesize that increased atrial oxidative stress and inflammation may play an important role in atrial nerve sprouting and heterogeneous sympathetic hyperinnervation during atrial fibrillation (AF). To test the hypothesis, we examined whether the antioxidant and anti-inflammatory treatment with probucol attenuates atrial autonomic remodeling in a canine model of AF produced by prolonged rapid right atrial pacing. Methods Twenty-one dogs were divided into a sham-operated group, a control group and a probucol group. Dogs in the control group and probucol group underwent right atrial pacing at 400 beats per minute for 6 weeks, and those in the probucol group received probucol 1 week before rapid atrial pacing until pacing stopped. After 6-week rapid atrial pacing, general properties including left atrial structure and function, atrial hemodynamics and the inducibility and duration of AF were measured in all the groups. Atrial oxidative stress markers and serum C-reactive protein (CRP) concentration were estimated. The degree of nerve sprouting and sympathetic innervation at the right atrial anterior wall (RAAW) and the left atrial anterior wall (LAAW) were quantified by immunohistochemistry, atdal norepinephrine contents were also detected. Atrial beta-nerve growth factor (beta-NGF) mRNA and protein expression at the RAAW and LAAW were assessed by real-time quantitative RT-PCR and Western blotting respectively. Results Atrial tachypacing induced significant nerve sprouting and heterogeneous sympathetic hyperinnervation, and the magnitude of nerve sprouting and hyperinnervation was higher in the RAAW than in the LAAW. Atrial beta-NGF mRNA and protein levels were significantly increased at the RAAW and LAAW, and the upregulation of beta-NGF expression was greater at the RAAW than at the LAAW in the control group. The beta-NGF protein level was positively correlated with the density of sympathetic nerves in all groups. Probucol decreased the increase of

    Full Text Available Subcapsular hepatic hematoma is a rare complication during pregnancy, but potentially lethal and usually related to severe pre-eclampsia or HELLP syndrome (hemolysis, elevated liver enzymes and diminished platelets. Maternal and perinatal mortality in these cases is high, hence the importance of early diagnosis and timely and multidisciplinary treatment. This paper is a review on the subject, held in Ebsco, Hinari and Sci databases.El hematoma subcapsular hepático es una complicación rara del embarazo, pero potencialmente letal, generalmente relacionada con pre-eclampsia grave o síndrome HELLP (hemólisis, enzimas hepáticas elevadas y plaquetas disminuidas. La mortalidad materna y perinatal en estos casos es elevada, de ahí la importancia del reconocimiento precoz y tratamiento oportuno y multidisciplinario. El presente trabajo constituye una revisión sobre el tema, realizada en las bases de dato Ebsco, Hinari y Scielo.

    The authors recently operated on a boy four years of age with acute epidural hematoma showing an extravasation on the cerebral angiogram. The hematoma (hematoma volume 125 ml) was evacuated 7 hours after the head injury. The postoperative course was quite uneventful, and he was discharged a month after surgery without any neurologic deficits. The authors reviewed the literature and found 4 cases of acute epidural hematoma with extravasations in infants and children. In all cases the operative results were good. The age incidence and frequency of occurence overall for acute epidural hematomas, extravasations on cerebral angiograms and their mechanism, and the length of time from injury to operation were also discussed. It should be emphasized that, for acute epidural hematoma in infants and children, the early diagnosis and early surgery are essential to save the patients.

  17. Giant right atrial myxoma

    International Nuclear Information System (INIS)

    Primary tumors of the heart are rare, their estimated incidence ranging between 0.0017-0.19%, and among them cardiac myxomas are the most common (50%). Right atrial localization is uncommon, occurring only in 15-20% of cases. Their clinical presentation ranges from an asymptomatic status to the presence of constitutional symptoms or symptoms pointing to the presence of cardiac obstruction or pulmonary embolism. A case is presented of a 36-year-old male patient with a history of asthenia, palpitations and reduced functional capacity. Transthoracic echocardiography revealed a large mass in the right atrium which prolapsed into the right ventricle and obstructed the tricuspid valve. The patient underwent cardiopulmonary bypass surgery and the mass (9x9 cm) was removed without any complication. Histological examination confirmed the diagnosis of myxoma.

    Full Text Available Reports of retropharyngeal hematoma have been scarce in the anesthesiology literature. We report a patient whose trachea was difficult to intubate due to retropharyngeal hematoma after stabbing to the neck. A woman with a knife injury to the common carotid artery required emergency carotid arterioplasty. When tracheal intubation was attempted, marked swelling of the posterior pharyngeal wall made the vocal cords impossible to visualize. Preoperative computed tomography showed a retropharyngeal hematoma. The patient required mechanical ventilation for 2 days.

    Complex fractionated atrial electrogram (CFAE) has been suggested to contribute to the maintenance of atrial fibrillation (AF). However, electrophysiologic characteristics of the left atrial myocardium responsible for genesis of CFAE have not been clarified. Non-contact mapping of the left atrium was performed at 37 AF onset episodes in 24 AF patients. Electrogram amplitude, width, and conduction velocity were measured during sinus rhythm, premature atrial contraction (PAC) with long- (L-PAC), short- (S-PAC) and very short-coupling intervals (VS-PAC). These parameters were compared between CFAE and non-CFAE regions. Unipolar electrogram amplitude was higher in CFAE than non-CFAE during sinus rhythm, L-, S- and VS-PAC (1.82 ± 0.73 vs. 1.13 ± 0.38, p genesis of CFAE.

    Full Text Available Brucellosis is a zoonotic disease. A characteristic clinical findings are fever, headache, arthralgia and splenomegali. Brucellosis occurs after direct contact with an infected animal or consumption of products of an infected animal. Subcapsular hematoma in the spleen is very rare complication of brucella infection. We report here, an 11 year old patient with brucellosis who admitted to our clinic with subcapsular non-traumatic spleen hematoma. Hematoma and clinical findings were resolved with doxicyclin and streptomycin combination. We emphasised that brucella infection should be keept in mind when non-traumatic subcapsular spleen hematoma occur.

    Full Text Available   Cholinergic and GABAergic fibers in the medial septal/diagonal band of Broca (MS/DB area project to the hippocampus and constitute the septo-hippocampal pathway, which has been proven in learning and memory. In addition, the hippocampus has bidirectional connections with the septum, which use this relation for self-regulation of cholinergic input.   The activity of septal and hippocampal neurons is modulated by several neurotransmitters including glutamatergic neurons from the entorhinal cortex, serotonergic fibers from the raphe nucleus, dopaminergic neurons from the ventral tegmental area (VTA, histaminergic cells from the tuberomammillary nucleus and adrenergic fibers from the locus coeruleus (LC. Thus, changes in the glutamatergic, serotonergic and etc. mediated transmission in the MS/DB may influence cholinergic or GABAergic transmission in the hippocampus.

    The deviated nose represents a complex cosmetic and functional problem. Septal surgery plays a central role in the successful management of the externally deviated nose. This study included 800 patients seeking rhinoplasty to correct external nasal deviations; 71% of these suffered from variable degrees of nasal obstruction. Septal surgery was necessary in 736 (92%) patients, not only to improve breathing, but also to achieve a straight, symmetric external nose. A graduated surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the nasal dorsum or nasal tip. The approach depended on full mobilization of deviated cartilage, followed by straightening of the cartilage and its fixation in the corrected position by using bony splinting grafts through an external rhinoplasty approach.

    The Cox-maze procedure for the restoration of normal sinus rhythm, initially developed by Dr. James Cox, underwent several iterations over the years. The main concept consists of creating a series of transmural lesions in the right and left atria that disrupt re-entrant circuits responsible for propagating the abnormal atrial fibrillation rhythm. The left atrial appendage is excluded as a component of the Maze procedure. For the first three iterations of the Cox- maze procedure, these lesions were performed using a surgical cut-and-sew approach that ensured transmurality. The Cox-Maze IV is the most currently accepted iteration. It achieves the same lesion set of the Cox- maze III but uses alternative energy sources to create the transmural lesions, potentially in a minimally invasive approach on the beating heart. High-frequency ultrasound, microwave, and laser energy have all been used with varying success in the past. Today, bipolar radiofrequency heat or cryotherapy cooling are the most accepted sources for creating linear lesions with consistent safety and transmurality. The robust and reliable nature of these energy delivery methods has yielded a success rate reaching 90% freedom from atrial fibrillation at 12 months. Such approaches offer a significant long-term advantage over catheter-based ablation, especially in patients having longstanding, persistent atrial fibrillation with characteristics such as dilated left atrial dimensions, poor ejection fraction, and failed catheter ablation. Based on these improved results, there currently is significant interest in developing a hybrid ablation strategy that incorporates the superior transmural robust lesions of surgical ablation, the reliable stroke prevention potential of epicardial left atrial appendage exclusion, and sophisticated mapping and confirmatory catheter-based ablation technology. Such a minimally invasive hybrid strategy for ablation may lead to the development of multidisciplinary "Afib teams" to

    2003-01-01

    Both percutaneous transcoronary alcohol septal reduction (ASR) and surgical myectomy are effective treatments to relieve left ventricular (LV) outflow tract obstruction in obstructive hypertrophic cardiomyopathy (HC). LV diastolic function was assessed by echocardiography in 57 patients with obstructive HC at baseline and 5 +/- 4 months after ASR (n = 37) or surgical myectomy (n = 20). LV outflow tract pressure gradient decreased from 65 +/- 40 to 23 +/- 21 mm Hg (p treatment. The ratio of the early-to-late peak diastolic LV inflow velocities, and the ratio of the early peak diastolic LV inflow velocity to the lateral mitral annulus early diastolic velocity determined by tissue Doppler imaging significantly decreased after the procedures (1.6 +/- 1.7 vs 1.0 +/- 0.7 and 15 +/- 8 vs 11 +/- 5, respectively), whereas LV inflow propagation velocity significantly increased (60 +/- 24 vs 71 +/- 36 cm/s). Left atrial size decreased from 29 +/- 7 to 25 +/- 6 cm(2) (p <0.05). Patients had a significant improvement in New York Heart Association functional class and in exercise performance. When comparing ASR with myectomy, no difference was found in the degree of change in any parameter of diastolic function. Thus, diastolic function indexes obtained by echocardiography changed after septal reduction interventions in patients with obstructive HC; this change was similar to that after surgical myectomy and ASR.

    2014-01-01

    Ventricular septal aneurysms are rare clinical entities and their certain prevalence and clinical significance are not well known. Most of them are thought to develop during or after the closure process of the accompanying ventricular septal defects. Although a majority of the patients are typically asymptomatic, the potential risks should also be kept in mind. We present a case of a membranous interventricular septal aneurysm that developed after surgery for subaortic valvular stenosis. The points that make our case worth reporting are development of the aneurysm after aortic surgery and lack of a concomitant ventricular septal defect. On the basis of the existence of an aortic valve surgery history and reports that do not mention any ventricular septal defect and ventricular septal aneurysm when she was operated, we suggest that the aneurysmatic formation in the membranous portion of the interventricular septum developed due to valve surgery in the postoperative wound healing period.

    Patients with acute intracranial hematomas often require surgical drainage within the first four hours after traumatic brain injury (TBI) to avoid death or severe neurologic disability. CT and MRI permit rapid, noninvasive diagnosis of hematomas, but can be used only at a major health-care facility. At present, there is no device for noninvasive detection and characterization of hematomas in pre-hospital settings. We proposed to use an optoacoustic technique for rapid, noninvasive diagnosis and monitoring of hematomas, including intracranial hematomas. Unlike bulky CT and MR equipment, an optoacoustic system can be small and easily transported in an emergency vehicle. In this study we used a specially-designed blast device to inflict TBI in rats. A near-infrared OPO-based optoacoustic system developed for hematoma diagnosis and for blood oxygenation monitoring in the superior sagittal sinus (SSS) in small animals was used in the study. Optoacoustic signals recorded simultaneously from the SSS and hematomas allowed for measurements of their oxygenations. The presence of hematomas was confirmed after the experiment in gross pictures of the exposed brains. After blast the hematoma signal and oxygenation increased, while SSS oxygenation decreased due to the blastinduced TBI. The increase of the oxygenation in fresh hematomas may be explained by the leakage of blood from arteries which have higher blood pressure compared to that of veins. These results indicate that the optoacoustic technique can be used for early diagnosis of hematomas and may provide important information for improving outcomes in patients with TBI or stroke (both hemorrhagic and ischemic).

    Development of collateral circulation belongs among the typical signs of aortic coarctation. Cerebral or spinal artery aneurysm formation with increased risk of subarachnoid hemorrhage represent the most common neurovascular complication of this disease. We report a case of a 20-year-old sportsman who developed acute non-traumatic paraplegia as a result of extensive spinal epidural hemorrhage from collateral vessels accompanying aortic coarctation which was unrecognized up to that time. To the best of our knowledge, acute spinal epidural hematoma as a complication of aortic coarctation has not been previously reported. (orig.)

    Full Text Available The authors report the case of a 50 year-old hypertensive male patient with a pontine hematoma. The clinical presentation was characterized by pure pyramidal deficit signs (no other signs or symptoms were present. A pure hemiplegia syndrome, although common in supratentorial lesions, is considered to be a rare event in pontine vascular lesions. The pathophysiologic mechanisms of these neurological findings are unclear. The exclusive involvement of the pyramidal tract in this case is likely due to a variation in the vascular anatomy of the pons but, in some cases, a vascular malformation may be the cause.

    Cerebral cortical contusions are one of the most common computed tomography findings in head-injured patients and common sequel of traumatic brain injury. These contusions tend to show a progressive increase in mass effect on repeated imaging, most small contusions do not require surgical evacuation. However, progression to subdural hematoma (SDH) in a late aspect is unique. Here we present a 71-year-old man with bifrontal contusion, who deteriorated 43 days after initial trauma with sudden onset of acute SDH. This unusual case suggests that neurosurgeons should be alert for the possibility of very late onset of acute SDH after bifrontal contusions.

    Complex muscular ventricular septal defect poses difficult surgical management and is associated with high morbidity and mortality despite advancements in surgical therapy. Device closure of muscular ventricular septal defect has been encouraging and has been used in hybrid approach at a few centres. However, device closure has some limitations in patients with complex muscular ventricular septal defect. We report a case of perventricular device closure of a complex muscular ventricular septal defect in a beating heart with entrapped right ventricular disc and its surgical management.

    1993-10-01

    Fourteen patients who presented to the University Hospital of Kuala Lumpur between June 1981 and June 1991 were reviewed retrospectively. Nasal septal abscesses are uncommon and therefore there are limited reports in the medical literature. Early diagnosis and immediate therapy is mandatory to avoid cosmetic nasal deformity or intracranial infection. Two out of the fourteen patients developed saddle nose deformity and septal perforation because of delay in treatment, the cases were misdiagnosed by non-otolaryngologist as turbinates swelling. The leading cause of nasal septal abscess was non-surgical trauma which accounted for about 85.7%. The commonest pathogenic organism isolated from the pus of nasal septal abscess was Staphylococcus aureus.

    A 57-year-old woman previously diagnosed with blue rubber bleb nevus syndrome(BRBNS) reported hematemesis. BRBNS is a rare vascular anomaly syndrome consisting of multifocal hemangiomas of the skin and gastrointestinal(GI) tract but her GI tract had never been examined. An upper gastrointestinal endoscopy revealed a large bleeding esophageal hematoma positioned between the thoracic esophagus and the gastric cardia. An endoscopic injection of polidocanol was used to stop the hematoma from bleeding. The hematoma was incised using the injectionneedle to reduce the pressure within it. Finally, argon plasma coagulation(APC) was applied to the edge of the incision. The esophageal hematoma disappeared seven days later. Two months after the endoscopic the rapy, the eso phage alulcerhealed and the hemangioma did not relapse. This rare case of a large esophageal hematoma originating from a hemangioma with BRBNS was treated using a combination of endoscopic therapy with polidocanol injection, incision, and APC.

    Full Text Available We describe a case in which a patient with a past medical history of ovarian cancer received a diagnostic renal biopsy for an incidentally discovered renal mass. During left robotic partial nephrectomy (RPN, a perinephric hematoma was encountered. The hematoma was not present on preoperative imaging and was likely a result of the renal biopsy. The renal cell carcinoma (RCC and the associated hematoma were widely excised with negative surgical margins. On follow-up imaging at five months postoperatively, a recurrent renal mass at the surgical resection bed and several new nodules in the omentum were detected. During completion left robotic total nephrectomy and omental excision, intraoperative frozen sections confirmed metastatic RCC. We believe that a hematoma seeded with RCC formed as a result of the renal biopsy, and subsequent disruption of the hematoma during RPN caused contamination of RCC into the surrounding structures.

    Full Text Available Abstract Background To evaluate whether the volume of blood suctioned during vacuum-assisted breast biopsy (VABB is associated with hematoma formation and progression, patient's age and histology of the lesion. Findings 177 women underwent VABB according to standardized protocol. The volume of blood suctioned and hematoma formation were noted at the end of the procedure, as did the subsequent development and progression of hematoma. First- and second-order logistic regression was performed, where appropriate. Cases with hematoma presented with greater volume of blood suctioned (63.8 ± 44.7 cc vs. 17.2 ± 32.9 cc; p Conclusion The likelihood of hematoma is increasing along with increasing amount of blood suctioned, reaching a plateau approximately at 80 cc of blood lost.

    2015-01-01

    Full Text Available Sublingual hematoma secondary to anticoagulation is a rare fatal condition. Hemorrhagic complications of warfarin are well-known. This particular case is unique because the patient was on warfarin for the past 2 years but did not develop the sublingual hematoma. However, a trauma by an attrited sharp cusp triggered the episode of the sublingual hematoma in this patient. Being a medical emergency, patient was promptly hospitalized in cardiac care unit and managed by medical team. The patient was transfused with 2 units of fresh frozen plasma and warfarin was temporarily stopped for 4 days. Alternate day regimen of warfarin was started after 4 days, and international normalized ratio dropped to 3. In dental management, enameloplasty of the mandibular first molar tooth was done to prevent trauma and ulcer development in the floor of the mouth. The hematoma resolved, and no new hematoma formation was observed for a period of 6 months.

    Full Text Available BACKGROUND: Atrial fibrillation and delayed gastric emptying (DGE are common after pancreaticoduodenectomy. Our aim was to investigate a potential relationship between atrial fibrillation and DGE, which we defined as failure to tolerate a regular diet by the 7(th postoperative day. METHODS: We performed a retrospective chart review of 249 patients who underwent pancreaticoduodenectomy at our institution between 2000 and 2009. Data was analyzed with Fisher exact test for categorical variables and Mann-Whitney U or unpaired T-test for continuous variables. RESULTS: Approximately 5% of the 249 patients included in the analysis experienced at least one episode of postoperative atrial fibrillation. Median age of patients with atrial fibrillation was 74 years, compared with 66 years in patients without atrial fibrillation (p = 0.0005. Patients with atrial fibrillation were more likely to have a history of atrial fibrillation (p = 0.03. 92% of the patients with atrial fibrillation suffered from DGE, compared to 46% of patients without atrial fibrillation (p = 0.0007. This association held true when controlling for age. CONCLUSION: Patients with postoperative atrial fibrillation are more likely to experience delayed gastric emptying. Interventions to manage delayed gastric function might be prudent in patients at high risk for postoperative atrial fibrillation.

    Background Differential diagnosis of isolated calf muscle vein thrombosis (ICMVT) and gastrocnemius hematoma is essential for early identification of deep vein thrombosis (DVT).This study aimed to investigate the diagnostic value of high-frequency color Doppler ultrasound for differential diagnosis of ICMVT and gastrocnemius hematoma.Methods A retrospective case series of 35 ICMVT (M∶F,21∶14; mean age (64.5±10.6) years) and 23 gastrocnemius hematoma (M∶F,16∶7; mean age (75.4±11.8) years) patients with bilateral/unilateral lower limb pain was conducted between January 2006 and September 2012.Characteristics and the morphology of high-frequency color Doppler ultrasonography of the lower limb deep vein,great saphenous vein,calf muscles,skin,and soft tissue were examined.Results ICMVT hypoechoic signals were characterized by long,tube-like masses on longitudinal sections and oval masses on transverse sections,with apparent muscle thrombosis boundaries,distal and proximal venous connections,and,often,lower limb DVT.Gastrocnemius hematoma hypoechoic signals were characterized by large volumes,enhanced posterior hematoma echo,hyperechoic muscle boundaries,no hematoma blood flow,and no DVT,and clear differences in trauma/exercise-and oral anticoagulant-induced hematomas were readily apparent.According to the measurement,the ratio of long diameter/transverse diameter (D/T) in ICMVT patients was about less than 2.0,whereas in gastrocnemius hematoma patients the ratio was more than 2.0.Early stage isoechoic and hypoechoic signals were detected with gradually increasing ovular anechoic areas.Partial muscle fibers in the hematoma due to muscle fractures were apparent.Conclusion High-frequency color Doppler ultrasound was found to be a sensitive and reliable method for differential diagnosis of ICMVT and gastrocnemius hematoma due to trauma and exercise or prolonged oral anticoagulant use.

    Full Text Available The safety and optimal strategy of the use of dabigatran versus uninterrupted warfarin in atrial fibrillation ablation is currently unclear. We performed a retrospective analysis between July 2011-October 2012 of all patients undergoing an AF ablation who received uninterrupted warfarin therapy (199 and the routine cessation of Dabigatran therapy (126 4 days pre-ablation. Major safety endpoints included: pericardial effusion (requiring pericardiocentesis, peripheral thromboembolism, CVA, and groin hematoma requiring blood transfusion. Minor endpoints included pericardial effusion and groin hematoma. Dabigatran was restarted the following day after ablation. The warfarin group was older, had a higher CHADS2, CHA2DS2VASc and HASBLED scores and greater prevalence of aortic plaque. The major complication rate was 2.0% in the warfarin group and 2.4% in the dabigatran group (P= 0.83. The minor complication rate was 2.5% in the warfarin group and <1% in the dabigatran group (P= 0.27. In the dabigatran group, there was one renal thromboembolic event 4 days post-ablation. All patients in the warfarin group who suffered a major complication required a blood transfusion. Cessation of dabigatran therapy 4 days pre AF ablation has a comparable safety profile to uninterrupted warfarin therapy.

    Full Text Available Atrial fibrillation is common in heart failure patients and is associated with increased mortality.  Pharmacologic trials have not shown any survival benefit for a rhythm control over a rate control strategy.  It has been suggested that sinus rhythm is associated with a survival benefit, but that the risks of anti-arrhythmic drug treatment and poor efficacy offset the beneficial effect.  Catheter ablation for atrial fibrillation can establish sinus rhythm without the risks of anti-arrhythmic drug therapy.  Data from randomized trials demonstrating a survival benefit for patients undergoing an ablation procedure for atrial fibrillation are still lacking.  Ablation of the AV junction and permanent pacing remain a treatment alternative in otherwise refractory cases.  Placement of a biventricular system may prevent or reduce negative consequences of chronic right ventricular pacing.  Current objectives and options for treatment of atrial fibrillation in heart failure patients are reviewed.

    The [symbol: see text] sinus-catheter was used to treat purulent sinusitis with septal perforation or defective septum of the sinuses. The procedure described implies simultaneous introduction of two sinus-catheters the functioning channels of which unite into one output by means of T-joint. The method has been successfully tried in the treatment of exudative and aggravated chronic purulent hemisinusitis (6 cases). The authors hold that communication between nasal sinuses is not a contraindication for sinus-catheter application. This fact widely extends potentialities of its use.

    Diffuse interlobular septal thickening (DIST) is an abnormality seen on high-resolution CT (HRCT) scanning of the thorax. While DIST may be present to variable extents in a number of lung conditions, it is uncommon as a predominant finding except in a few entities. This report features an ex-coal miner, thought to have coal workers' pneumoconiosis (CWP), in whom the HRCT scan showed no evidence of CWP and instead showed DIST. The patient's condition progressed incessantly towards death from severe secondary pulmonary hypertension. The case links fatal pulmonary hypertension to DIST, a pattern not previously described in coal workers.

    Although clinical outcomes for septal ablation in treating left ventricular outflow tract obstructions are generally favorable, a variety of complications have been reported including a high incidence of right bundle branch block. These complications may be attributed to anatomic variability of the dominant septal perforator. We used Dual Source CT Coronary Angiography (DS-CTA) to determine the location of the termination point of the dominant septal perforator as well as the distance of the termination point from the mitral annulus in patients undergoing DS-CTA. One-hundred-fourteen DS-CTA scans were retrospectively reviewed by two observers by consensus. The left ventricle was divided into anterior wall, anterioseptum, and inferioseptum. For each segment, the myocardium was divided into three layers (1) right ventricular side, (2) mid portion, and (3) left ventricular side. The zone of termination of the dominant septal perforator was identified as well as the distance of the termination point from the mitral annulus. The dominant septal perforator terminated in the right ventricular side of the anterioseptum in 86 of the 118 visualized terminations (73%) and in the left ventricular anterior wall in 6 visualized terminations (5%). On average, the dominant septal perforator terminated 26.3 +/- 8.6 mm from the mitral annulus. In the majority of cases, the dominant septal perforator terminates in the right ventricular side of anterioseptum. In addition, there is great variability in the distribution of the termination point of the dominant septal perforator from the mitral annulus. PMID:19918876

    Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS. We report here on a case of HFRS that caused massive perirenal hematoma, and this was treated with superselective renal artery embolization.

    Full Text Available Background. Large craniotomy for acute subdural hematoma is sometimes too invasive. We report good outcomes for two cases of neuroendoscopic evacuation of hematoma and contusion by 1 burr hole surgery. Case Presentation. Both patients arrived by ambulance at our hospital with disturbed consciousness after falling. Case 1 was an 81-year-old man who took antiplatelet drugs for brain infarction. Case 2 was a 73-year-old alcoholic woman. CT scanning showed acute subdural hematoma and frontal contusion in both cases. In the acute stage, glycerol was administered to reduce edema; CTs after 48 and 72 hours showed an increase of subdural hematoma and massive contusion of the frontal lobe. Disturbed consciousness steadily deteriorated. The subdural hematoma and contusion were removed as soon as possible by neuroendoscopy under local anesthesia, because neither patient was a good candidate for large craniotomy considering age and past history. 40%~70% of the hematoma was removed, and the consciousness level improved. Conclusion. Neuroendoscopic removal of acute subdural hematoma and contusion has advantages and disadvantages. For patients with underlying medical issues or other risk factors, it is likely to be effective.

    To explore the infarct sites in patients with inferior wall acute myocardial infarction (AMI) concomitant with ST segment elevation in leads V1-V3 and leads V3R-V5R.Methods Five patients diagnosed as inferior, right ventricular, and anteroseptal walls AMI at admission were enrolled. Electrocardiographic data and results of isotope 99mTc-methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging and coronary angiography (CAG) were analyzed.Results Electrocardiogram showed that ST segment significantly elevated in standard leads Ⅱ, Ⅲ, aVF, and leads V1-V3 , V3R-V5R in all five patients. The magnitude of ST segment elevation was maximal in lead V1 and decreased gradually from lead V1 to V3 and from lead V1 to V3R-V5R. There was isotope 99mTc-MIBI myocardial perfusion imaging defect in inferior and basal inferior-septal walls. CAG showed that right coronary artery was infarct-related artery.Conclusions The diagnostic criteria for basal inferior-septal wall AMI can be formulated as follows: ( 1 ) ST segment elevates ≥2 mm in lead V1 in the clinical setting of inferior wall AMI; (2) the magnitude of ST segment elevation is the tallest in lead V1 and decreases gradually from lead V1 to V3 and from lead V1 to V3R-V5R. With two conditions above, the basal inferior-septal wall AMI should be diagnosed.

  9. Extracerebral hematoma and parenchymal lesion in computerized tomography of pediatric patients with severe head injury

    International Nuclear Information System (INIS)

    Fifty children (13 years of age or under) with acute, severe head injury were analyzed, with special reference to the relations between initial computerized tomography (CT) findings, clinical severity, and outcome. The severity and the outcome were evaluated using the Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS), respectively, adoption of GCS scoring being restricted to patients 3 years of age or over. Twenty-three patients (46 %) showed extracerebral hematomas. The most common extracerebral hematoma was the acute subdural hematoma, which comprised 24 % of the cases; epidural hematomas were found in 9 cases (18 %). These figures coincided with the reported results of adult cases in severe head injury. All the epidural hematoma cases showed ''normal'' parenchymal lesion, and carried less clinical severity and better outcome. This might suggest that more trivial injury would cause the epidural hematoma in children than in adults. Hemispheric swelling was commonly seen in patients with acute subdural hematoma and was generally associated with low GCS scores (mean 4.8) and poor outcome (63 % mortality). Compared with that in adults, hemorrhagic lesion in children was less often associated with extracerebral hematoma, and the outcome and severity of the cases with this lesion depended mainly on the multiplicity and the location of the hemorrhage. Eleven cases fulfilled the criteria of diffuse cerebral swelling, namely, slit-like ventricles and obliterated perimesencephalic cisterns, and only one had an associated subdural hematoma. Forty-two patients (84 %) achieved a good recovery or a moderate disability. None were severely disabled or vegetative, and the overall mortality rate was 16 %. Patients with GCS scores of 3 to 5 were uniformly poor in outcome (60 % of mortality), regardless of parenchymal lesions, whereas those with GCS scores of 6 to 8 had only 8 % mortality. (J.P.N.)

She had previous peptic ulcer disease and a long-standing history of gastroesophageal reflux disease. Her medications included acetylsalicylic acid and rabeprazole. Electrocardiogram and troponin analyses were negative for ischemic heart disease. The emergency physician suspected an aortic dissection, and computed tomography (CT) chest and abdomen scans were performed with and without IV and oral contrast. The aorta was normal and the noncontrast images demonstrated a hyperdense mass (not shown) that did not enhance consistent with a large intramural hematoma extending from the upper esophagus (level of T2 vertebral body) to the fundus of the stomach (Figures 1A and B).

    Foreign accent syndrome (FAS), a rare disorder characterized by the emergence of a new accent perceived as foreign by listeners, is usually reported with left brain damage. We here report the case of a 28-year-old native Brazilian who appeared, to the examiner, to show a North American accent during recovery from Broca's aphasia. The lesion was due to a frontal hematoma. Without referring specifically to speech, we asked 10 independent observers to comment on a videotape of the patient's interview. Seven reported that the patient had a foreign accent, while 3 simply noted a 'strange' accent. The observers did not agree on the origin of the accent, 5 identifying it as Spanish, 1 as German, and 1 as south Brazilian. These findings suggest that FAS is not due to the acquisition of a specific foreign accent, but to impairment of the suprasegmental linguistic abilities (tone, accent, pauses, rhythm, and vocal stress) that make it possible to distinguish native language.

    During septorhinoplasty, septal cartilage is frequently resected for various purposes but the L-strut is preserved. Numerous materials are inserted into the nasal dorsum during dorsal augmenation rhinoplasty without considering nasal structural safety. This study used a finite element method (FEM) to redefine the septal L-strut, to prevent collapse as pressure moved from the rhinion to the supratip breakpoint on the nasal dorsum and as the contact percentage between the caudal L-strut and the maxillary crest changed. We designed a 1-cm-wide L-strut model based on computed tomography data. At least 45% of the width of the L-strut in the inferior portion of the caudal strut must be preserved during septoplasty to stabilize the septum. In augmentation rhinoplasty, the caudal L-strut must either be preserved perfectly or reinforced to prevent collapse or distortion of the L-strut. The dorsal augmentation material must be fixed in an augmentation pocket to prevent movement of graft material toward the supratip breakpoint, which can disrupt the L-strut. We conducted a numerical analysis using a FEM to predict tissue/organ behavior and to help clinicians understand the reasons for target tissue/organ collapse and deformation. PMID:27073993

Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk

    Full Text Available Spinal subdural hematoma is a rare disorder and can be caused by abnormalities of coagulation, blood dyscrasias, lumbar puncture, trauma, underlying neoplasm, and arteriovenous malformation. We discuss an unusual case of an elderly woman who presented with spontaneous spinal subdural hematoma and developed massive rebleeding on the third day following initial evacuation of hematoma. This case illustrates that a patient with routine normal coagulation profile and adequate hemostasis can still harbor platelet dysfunction (in present case due to polycythemia and later on can manifest as rebleeding and neurological deterioration.

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

    Abstract Obturator nerve injury is a known injury after robot-assisted laparoscopic radical prostatectomy (RALP) and patients often present with motor and sensory deficits in the immediate postoperative period. We describe a 65-year-old male who presented with motor deficits, indicative of obturator neurapraxia after RALP upon waking from anesthesia. Work-up revealed an expansile hematoma possibly compressing the obturator nerve. After evacuation of the hematoma, the patient had immediate improvement of his neurologic deficits. Our patient's clinical vignette illustrates the importance of considering postsurgical hematoma in the differential diagnosis when patients present with signs and symptoms of obturator neurapraxia after RALP.

    We present the case of an 86-year-old female with spontaneous spinal epidural hematoma. Although T1- and T2-weighted images showed the dilated posterior epidural space at the cervical spine, this finding was non-specific on conventional magnetic resonance imaging obtained 15 h after the onset of symptoms. Diffusion-weighted imaging with the use of periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER), which clearly revealed the high intensity hematoma, was useful for detection and diagnosis of acute spinal epidural hematoma.

    Atrial fibrillation requires a trigger that initiates the arrhythmia and substrate that favors perpetuation. Cardiac mapping is necessary to locate triggers and substrate so that an ablation strategy can be optimized. The most commonly used cardiac mapping approach is isochronal or activation mapping, which aims to create a spatial model of electrical wavefront propagation. Historically, activation mapping has been successful for mapping point source and single or double wave reentrant arr...

    Full Text Available Traumatic retroclival hematomas are uncommon lesions usually associated with significant trauma. Majority of the reported hematomas are epidural; and in the pediatric population. Retroclival acute subdural hematomas (RSDH are very rare, with only two previous cases reported in English literature. An 18-year-old man presented with headache and no deficits following an accident. Computer tomography (CT scan and magnetic resonance imaging (MRI showed an acute RSDH extending into the spinal subdural space. He developed bilateral sixth nerve palsies, with symptoms of raised intracranial pressure within the next 24 hours. He underwent evacuation of hematoma with a good outcome. Another 19-year-old man presented with neck pain following a fall from a moving bus. He had no neurological deficits. CT scan showed a RSDH extending across the craniovertebral junction. He was managed conservatively with good outcome.

    2016-01-01

    Clinical outcomes are positively associated with hematoma absorption. The monocyte-macrophage scavenger receptor, CD163, plays an important role in the metabolism of hemoglobin, and a soluble form of CD163 is present in plasma and other tissue lfuids;therefore, we speculated that serum CD163 affects hematoma absorption after intracerebral hemorrhage. Patients with intracerebral hemorrhage were divided into high-and low-level groups according to the average CD163 level (1,977.79 ± 832.91 ng/mL). Compared with the high-level group, the low-level group had a signiifcantly slower hematoma absorption rate, and signiifcantly increased National Institutes of Health Stroke Scale scores and modiifed Rankin Scale scores. These results suggest that CD163 promotes hematoma absorption and the recovery of neurological function in patients with intracerebral hemorrhage.

    2015-04-01

    Full Text Available Alcohol abuse is associated with both potentiating and antagonizing hemostatic states. Liver cirrhosis is an independent causal factor for many bleeding complications. The long-term effects of alcohol abuse coupled with advanced liver cirrhosis are additive in favor of bleeding. We report the case of a patient with a history of alcohol abuse who presented with liver cirrhosis and nontraumatic muscle hematoma diagnosed as a spontaneous hematoma of the gastrocnemius muscle. He was managed conservatively with infusions of fresh frozen plasma and platelets, which resulted in resolution of the hematoma. The pathogenesis of ‘spontaneous' muscle hematoma remains anecdotal, but since it is reported in patients on anticoagulant therapy or with hemostatic disorders, it is hypothetically related to severely deranged coagulation. Here we review the relevant literature pertaining to the pathogenesis, presentation and treatment options available for treating this often fatal complication of bleeding diatheses.

    2010-01-01

    Full Text Available Once considered as nothing more than a nuisance after cardiac surgery, the importance of postoperative atrial fibrillation (POAF has been realized in the last decade, primarily because of the morbidity associated with the condition. Numerous causative factors have been described without any single factor being singled out as the cause of this complication. POAF has been associated with stroke, renal failure and congestive heart failure, although it is difficult to state whether POAF is directly responsible for these complications. Guidelines have been formulated for prevention of POAF. However, very few cardiothoracic centers follow any form of protocol to prevent POAF. Routine use of prophylaxis would subject all patients to the side effects of anti-arrhythmic drugs, while only a minority of the patients do actually develop this problem postoperatively. Withdrawal of beta blockers in the postoperative period has been implicated as one of the major causes of POAF. Amiodarone, calcium channel blockers and a variety of other pharmacological agents have been used for the prevention of POAF. Atrial pacing is a non-pharmacological measure which has gained popularity in the prevention of POAF. There is considerable controversy regarding whether rate control is superior to rhythm control in the treatment of established atrial fibrillation (AF. Amiodarone plays a central role in both rate control and rhythm control in postoperative AF. Newer drugs like dronedarone and ranazoline are likely to come into the market in the coming years.

    Full Text Available Abstract Introduction Vascular complications related to cup-fixating screws penetrating the medial acetabular wall during total hip arthroplasty are not uncommon but rarely are associated with serious adverse events in the late post-operative period. Case presentation We present the case of a 77-year-old Japanese woman who developed progressive extensive bone resorption and large hematoma in the acetabulum 13 years after total hip arthroplasty. On admission to our hospital, she was on oral warfarin (1.5mg/day for atrial fibrillation. About 5 months after the initiation of anticoagulant therapy, she suffered a major fall followed by massive subcutaneous and pelvic girdle bleeding, predominantly on the medial side of the right thigh, but a fracture or damage of total hip arthroplasty was not evident on an emergency orthopedic evaluation. One year after the accident, a routine follow-up examination showed an asymptomatic osteolytic lesion in the acetabulum on the right pelvis, and 2 years later our patient noticed progressive pain in her right hip during walking. A large osteolytic lesion was noted in the right acetabulum on a plain radiograph. On high-resolution computed tomography and magnetic resonance imaging, a huge granulomatous lesion in the acetabulum was suggestive of chronic hematoma in intrapelvic and extrapelvic gluteal regions. A closer computed tomography examination showed that one of the screws used for fixation of the acetabular component in the total hip arthroplasty had penetrated the acetabular bone and had reached the pelvic cavity. Surgery was performed in a single session by means of two approaches: anterior midline transperitoneal address to resect the low-density mass lesion followed by posterolateral acetabular implant re-settlement. Conclusions Though rare, total hip arthroplasty-related late vascular complications could be serious and potentially affect the limb and quality of life.

    Shuker, Sabri T

    2016-07-01

    This article aims to bring attention to the morbidity and fatality of hemorrhage, how expanding hematoma and air compromise neck/face N/F injuries and present challenges. Large neck vessel ballistic injuries may lead to hemorrhage and expanding hematoma, resulting in airway compromise, due to injuries to the internal and/or external carotid arteries, internal jugular veins "internal carotid artery, external carotid artery, internal jugular vein," and the external carotid artery deep branches. This also leads to injuries to the cervical fascial layers (barriers of deep spaces) that facilitate pooling blood and hematoma into compartmental and large potential space which effects the pharynx, larynx, esophagus, and trachea.The expanding hematomas distort neck anatomical landmarks so "no neck zones" classifications are applicable. As the spectrum of injuries continues to evolve, the clinical characterization needs a new categorization based on compartmental hematoma and potential space anatomical location like retropharyngeal, parapharyngeal, sublingual, submandibular spaces, retrobulbar, and cheek compartment space hematomas.Presence of symptoms and location of the hematoma generally dictate what type of procedure is needed and how urgently it needs to be appropriately performed.Two unusual patients of pseudoaneurysms facial artery injuries with extravasation of blood producing a pulsating hematoma are referred to. Another patient considers large internal carotid artery injuries pseudoaneurysms revealed in angiography.The immediate management of life-saving patients requires aggressive airway maintenance at the scene, conscious victim will often obtain a posture that clears his airway and the semiconscious or unconscious put him in prone position. Air compromise may need emergency intubation, large bore cannula cricothyroidotomy, cricothyrotomy and at medical facilities tracheostomy. PMID:27315316

    2003-01-01

    Objective To study the effect of endoscopic-assisted keyhole operation (EAKO) on treating hypertensive intracranial hematomas and the value of our patent dissector appli ed during the operation.Methods A total of 25 patients with hypertensive intracranial hematomas underwent endos copic-assisted keyhole evacuation, during which, the viewing dissector, which h ad recently achieved national patent, was connected to the tip of endoscope and used to help dissect hematomas. The outcome of this procedure were compared wit h those of 22 comparable cases undergone conventional surgical treatment (large or smaller craniotomy). The items for comparison included the volum e of remaining hematoma, the duration of operation, postsurgical Glasgow Coma Sc ale (GCS) and Glasgow Outcome Scale (GOS).Results Remaining hematoma was ascertained 48 h after operation with the use of computerized tomography (CT) scans. In the case of EAKO, nearly complete evacuation (>84%) was achieved in 21 cases; GCS was evaluated at 7 d postsurgery result ing in GCS >12 in 9 patients, GCS 9-12 in 12 patients and GCS <9 in 4 patients. The follow-up period ranged from 6 to 21 mon. GOS was estimated at half a year and good recovery rate as defined by GOS was assigned to 76% of the EAKO pa tients. There are significant differences in the volumes of remaining hematomas and the duration of operation between the EAKO and craniotomy group (P<0.0 5). In addition, better clinical outcomes were obtained in EAKO. Conclusion EAKO has the advantage of being minimally invasive, improving surgical results and the prognosis of hypertensive intracranial hematoma patients. We conclude th at keyhole operation is a safe, effective alternative for removal of hypertensiv e intracranial hematoma, particularly during acute stages.

Case Description: We present the case of a 7-year-old boy who was medicated with warfarin and aspirin due to a hypoplastic left ventricle and fell from a rock wherein he hit his head in the frontal region. Although a computed tomography scan of the head revealed no intracranial lesion, an extracranial hematoma was found to extend over the cranial sutures, leading to the diagnosis of subgaleal hematoma. The hematoma continued to grow gradually despite the cessation of warfarin and aspirin therapy immediately after the head trauma. Since the patient′s headache and anemia were progressing as the hematoma enlarged, removal of the hematoma was performed 3 days after admission. Endoscopic hematoma removal was planned to enable accurate coagulation of the sites of bleeding and removal of the maximal amount of hematoma through minimal incision. The hematoma was completely removed, and the patient′s postoperative course was excellent with alleviation of both the anemia and the headache. No sign of hematoma recurrence could be detected during 2 years follow-up. Conclusion: An angled endoscope can allow visualization of the deep subgaleal space, and this technique enabled direct visualization of the bleeding sites and accurate coagulation to prevent recurrence of hematoma. Endoscopic techniques, such as minimally invasive techniques, can allow sufficient removal of subgaleal hematoma with minimal morbidity, especially in patients such as ours.

  10. Changes in plasma atrial natriuretic factor in patients with idiopathic atrial fibrillation

    International Nuclear Information System (INIS)

    To observe the changes in plasma atrial natriuretic factor (AFN) in patients with idiopathic atrial fibrillation and investigate its mechanism, plasma ANF, platelet count and hematocrit were detected in 21 cases with transient idiopathic atrial fibrillation (group A, A1 representing attack, while A2 termination), 28 with persistent idiopathic atrial fibrillation (group B), 27 suffered from rheumatic heart disease with mitral stenosis and persistent atrial fibrillation (group C), 32 with transient supraventricular tachycardia (group D) and 20 normal controls (group E). It was found that the level of ANF was significantly higher in patients with attacking transient idiopathic atrial fibrillation than that in group A2, D and E (P 0.05), while there was significant difference in hematocrit in group A1 compared with group A2, D, E (P < 0.01). It suggested that ANF and hematocrit play an important role in the attack of idiopathic atrial fibrillation

    Full Text Available Abstract Background Abdominal wall hematomas are an uncommon cause of acute abdominal pain and are often misdiagnosed. They are more common in elderly individuals, particularly in those under anticoagulant therapy. Most abdominal wall hematomas occur in the rectus sheath, and hematomas within the oblique muscle are very rare and are poorly described in the literature. Here we report the case of an oblique muscle hematoma in a middle-aged patient who was not under anticoagulant therapy. Case presentation A 42-year-old Japanese man presented with a painful, enlarging, lateral abdominal wall mass, which appeared after playing baseball. Abdominal computed tomography and ultrasonography showed a large soft tissue mass located in the patient’s left internal oblique muscle. A diagnosis of a lateral oblique muscle hematoma was made and the patient was treated conservatively. Conclusion Physicians should consider an oblique muscle hematoma during the initial differential diagnosis of pain in the lateral abdominal wall even in the absence of anticoagulant therapy or trauma.

    Full Text Available The retroperitoneal hematoma can have, mainly, a traumatic etiology - blunt abdominal trauma (falls from height, road accidents, aggression of any kind, etc., or open (incised wounds, puncture, penetration or gunshot wounds. Ruptured arterial aneurysms can cause hemorrhage in the retroperitoneal space. There is also spontaneous retroperitoneal trauma in patients with chronic treatment with anticoagulant or antiaggregant drugs (1. Hemorrhage in the retroperitoneal space can be iatrogenic, after surgical, open or laparoscopic, interventions (2, 3. A particular type of retroperitoneal hematoma is the psoas muscle hematoma in patients with chronic oral anticoagulant treatment (Acenocumarol, Warfarin. The management of the retroperitoneal hematoma, whatever the cause may be, is, for most of the time, difficult. In case of traumatic etiology, the retroperitoneal hematoma is not the only lesion, being frequently associated with severe hollow or parenchymal organs injury or vascular lesions, which highlights the importance of a complete and precise clinical inventory of the lesions. The decision between an aggressive, surgical or interventional attitude and a conservative one, with monitoring, is often taken under pressure. Especially difficult are the cases in which the imaging results of the lesions is uncertain, when the patient presents hemodynamic instability, when other lesions can not be excluded, or when the parietal peritoneum is ruptured and the retroperitoneal hematoma gets into the peritoneal cavity, the patient presenting haemoperitoneum. For most of the time, these cases have indication for exploratory laparotomy, for a diagnostic, not therapeutic, goal.

    Coronary fistulae and ventricular septal perforation are very rare clinically, and even less caused by cardiac leiomyosarcoma. A case is reported that a 67-year-old female had cardiac leiomyosarcoma with progressive heart failure and coronary fistulae and ventricular septal perforation. This case was special since all ante-mortem examinations and cardiac surgery failed to detect the presence of any abnormal car-diac mass. Therefore, the malignant cardiac tumors could appear in an invasive form without mass and be one of the causes of the coronary fistulae and ventricular septal perforation.

    Primary septal agenesis (PSA) is a rare brain malformation that can be isolated or part of developmental brain abnormalities (holoprosencephaly, septo-optic dysplasia or cortical malformation). Such associated malformation can be subtle, leading to difficulties in the prenatal management of PSA. Moreover, the neurological prognosis of isolated PSA remains debatable. The aims of the study were to specify the patterns and frequency of brain malformations associated with septal agenesis (SA), to identify the clinical prognosis, and to discuss the aetiology of PSA with the new insights provided by molecular genetics. The study consisted of a 14-year retrospective review of brain MRI in 34 patients having PSA (mean age, 5 years). Chiasm and optic nerves were not evaluated. Post-hydrocephalus SA or incomplete data were excluded. The clinical data were correlated to the MRI patterns. The study disclosed 82.5% associated lesions with MRI (28/34): 11 neuronal migration disorders, 9 holoprosencephalies (HP), 7 pituitary stalk interruptions, 1 corpus callosum partial agenesis; 17.5% (6/34) of cases were apparently isolated PAS. Clinically, the patients had motor dysfunction in 68% (23/34), mental retardation in 65% (22/34), blindness in 24% (8/34), endocrinological defects in 21% (7/34) and epilepsy in 18% (6/34) of cases. Nine percent of patients (3/34) were neurologically normal (including one with scoliosis and two infants younger than 2 years at the last follow-up). Patients with bilateral cortical anomalies and HP (even if mild) had the worst neurological prognosis. A severe motor impairment was present without evidence of hemispheric anomaly in 12% of patients (4/34). Interestingly, the frontal lobes were involved in 90% of cortical anomalies and HP, supporting the malformative aetiology of PSA. PSA rarely appears isolated and severe psychomotor impairment may occur in apparently isolated forms. These unfavourable results should be highlighted and need to be confirmed

    ABSTRACT Objective: This paper deals with the investigation of the effects of nasal septal deviation evaluated by acoustic rhinometry (ARM) in the success of tympanoplasty surgery. Subject and Methods: All patients who underwent tympanoplasty surgery by the same surgeon were reviewed. The patients with nasopharyngeal or nasal masses, polyps, symptoms of allergic rhinitis or rhinosinusitis, or concha bullosa were excluded from the study. Forty patients who underwent tympanoplasty at least one year ago were included in the study. The patients were divided into two groups according to the graft success results. Acoustic rhinometry evaluations of the patients were performed. Results: There were 25 and 15 cases in the intact graft (group A) and re-perforated group (group B), respectively. For the same side of the operated ear, ARM values of group A were 0.47 cm 2 at the first narrowest cross-sectional area (MCA 1), 0.43 cm2 at the second narrowest cross-sectional area (MCA 2), 1.51 cm3 volume at the first 2 cm of the nasal cavity (Vol 1) and 3.33 cm3 volume between the second and fifth cm of the nasal cavity (Vol 2). Acoustic rhinometry values of group B were 0.50 cm2, 0.47 cm2, 1.60 cm3 and 3.19 cm3 for MCA 1, MCA 2, Vol 1, and Vol 2, respectively. Conclusion: The results of this study showed that nasal septal deviation may not affect the success of tympanoplasty surgery, and septoplasty may not be necessary before ear surgery. PMID:26624593

    Full Text Available Purpose: Pericardial adipose tissue had been shown to exert local effects on adjacent cardiac structures. Data regarding the mechanistic link between such measures and left atrial (LA structural/functional remodeling, a clinical hallmark of early stage heart failure (HF and atrial fibrillation (AF incidence, in asymptomatic population remain largely unexplored. Methods: This retrospective analysis includes 356 subjects free from significant valvular disorders, atrial fibrillation, or clinical HF. Regional adipose tissue including pericardial and periaortic fat volumes, interatrial septal (IAS, and left atrioventricular groove (AVG fat thickness were all measured by multidetector computed tomography (MDCT (Aquarius 3D Workstation, TeraRecon, San Mateo, CA, USA. We measured LA volumes, booster performance, reservoir capacity as well as conduit function, and analyzed their association with adiposity measures. Results: All four adiposity measures were positively associated with greater LA volumes (all P < 0.05, while IAS and AVG fat were also related to larger LA kinetic energy and worse reservoir capacity (both P < 0.01. In multivariate models, IAS fat thickness remained independently associated with larger LA volumes, increased LA kinetic energy and ejection force (β-coef: 0.17 & 0.15, both P < 0.05, and impaired LA reservoir and conduit function (β-coef: −0.20 & −0.12, both P < 0.05 after adjusting for clinical variables. Conclusion: Accumulated visceral adiposity, especially interatrial fat depots, was associated with certain LA structural/functional remodeling characterized by impaired LA reservoir and conduit function though augmented kinetic energy and ejection performance. Our data suggested that interatrial fat burden may be associated with certain detrimental LA functions with compensatory LA adaptation in an asymptomatic population.

    Full Text Available OBJECTIVE: Mitral valve surgery can be performed through the trans-atrial or the trans-septal approach. Although the trans-atrial is the preferred method, the trans-septal approach has also been used recently and has a particular value in beating-heart mitral valve surgery. Herein we report our experience with beating-heart mitral valve surgery via trans-septal approach, and discuss its advantages and pitfalls. METHODS: Between 2000 and 2007, 214 consecutive patients were operated upon utilizing beating heart technique for mitral valve surgery. The operation was performed via transseptal approach with the aorta unclamped, the heart beating, with normal electrocardiogram and in sinus rhythm. RESULTS: Mean age was 56.03 ± 13.93 years (range: 19-86 years; median: 56 years. There were 131 (61.2% males and 83 (38.8% females. Of the prostheses used, 108 (50.5% were biological, and 39 (18.2% were mechanical. Mitral repairs were performed in 67 (31.3% patients. Mean hospital stay was 17.4 ± 20.0 days (range: 3-135 days; median: 11 days. Intra-aortic balloon pump (IABP utilization was required in 12 (5.6% of 214 patients. One-month mortality was 7.4%, and re-operation for bleeding was needed in 15 (7% patients. CONCLUSIONS: Beating-heart mitral valve surgery is an option for myocardial protection in patients undergoing mitral valve surgery. This technique is facilitated by the trans-septal approach due to reduced aortic insufficiency and improved visualization of the mitral apparatus.OBJETIVO: A cirurgia da valva mitral pode ser feita via transatrial ou transeptal.

    Full Text Available Background: The role of subchorionic hematoma (SCH in the first trimester of pregnancy remains open for discussion. Some authors claim that SCH does not affect the pregnancy; others have found that it is a serious risk factor for adverse pregnancy outcome. The objective of the present study was to explore the outcomes of pregnancy in patients with SCH diagnosed in the first trimester. Methods and Results: The study involved 194 pregnant women who were in terms of 6 to12 weeks: 115 women with SCH (Group 1 and 79 apparently healthy pregnant women (Group 2. A missed miscarriage was observed in 27/23% women of Group 1 and in 4/5% of Group 2 (P<0.05, recurrent threat of miscarriage in 27/23% and in 4/5%, recurrent bleeding in 14/12% and 2/3%, and the short cervix syndrome in 22/19% and 5/6% women, respectively. Conclusion: The results of our study show that the presence of SCH adversely affects the first half of pregnancy, leading to recurrent threatened abortion, recurrent threat of miscarriage, missed miscarriage until 12 weeks of gestation, and the short cervix syndrome.

    A non-invasive microwave device for the detection of epi/subdural hemorrhaging (hematoma) is under current development. The final device will be highly portable and allow real time assessment of head injuries, thereby satisfying early detection needs of the field technician as well as providing a tool for repetitious monitoring of high-risk individuals. The device will adopt the advanced technology of micropower impulse radar (MIR) which is a state of the art low cost ultra wide band (UWB) microwave radar developed here at LLNL. It will consist of a MIR transmitting and receiving module, a computer based signal processing module, and a device-to-patient signal coupling module--the UWB antenna. The prototype design is being guided by the needs of the patient and the practitioner along with the prerequisites of the technology including issues such as the specificity of the device, efficacy of diagnosis, accuracy, robustness, and patient comfort. The prototype development follows a concurrent approach which .includes experiments designed to evaluate requirements of the radar and antenna design, phantom development to facilitate laboratory investigations, and investigation into the limits of adapting pre-existing non-medical MIR devices to medical applications. This report will present the accomplishments and project highlights to date in the fiscal year 1999. Future project projections will also be discussed.

    Fat-preserving lower blepharoplasty techniques are increasingly common, but to date there has been insufficient data comparing the results of fat repositioning and septal reset. The authors compared the aesthetic results of the 2 methods using statistical analysis. A total of 120 patients, who had undergone transconjunctival subperiosteal fat repositioning from February 2008 to April 2009, were included. Group 1 (71 patients) underwent fat reposition with pedicled infraorbital fat redraping. Group 2 (49 patients) underwent septal reset to reposition the underlying fat. Documentation of the results with grading (grade 0-III) by 2 surgeons was done, and the results were evaluated for clinical improvement.Septal reset showed statistical significance on grade improvement compared to direct fat manipulation methods in the patients with grade II and grade III deformities. Septal reset also showed a trend for a higher degree of improvement compared to the latter. There were no major postoperative complications. PMID:23722575

    Atrial fibrillation (AF) contributing to the increasing mortality risk is the most common disease in clinical practice. Owing to the side effects and relative inefficacy of current antiarrhythmic drugs, some research focuses on renin-angiotensin-aldosterone system (RAS) for finding out the new treatment of AF. The purpose of this study is to confirm whether aliskiren as a proximal inhibitor of renin, which completely inhibits RAS, has beneficial effects on atrial structural remodeling in AF. In this study, rapid atrial pacing was induced at 500 beats per minute for 2 weeks in a canine model. A different dose of aliskiren was given orally for 2 weeks before rapid atrial pacing. HE staining and Masson's staining were used for analysis of myocardial fibrosis. TGF-β1, signal pathways, and pro-inflammatory cytokines were shown for the mechanism of structural remodeling after the treatment of aliskiren. Serious atrial fibrosis was induced by rapid atrial pacing, followed by the elevated TGF-β1, upregulated MEK and ERK1/2, and increased inflammatory factors. Aliskiren could apparently improve myocardial fibrosis by reducing the expression of TGF-β1, inhibiting MEK and ERK1/2 signal pathways, and decreasing IL-18 and TLR4 in both serum and atrial tissue. In conclusion, aliskiren could prevent atrial structural remodeling from rapid atrial pacing for 2 weeks. Aliskiren may play a potential beneficial role in the treatment of AF induced by rapid atrial pacing. PMID:27118660

    Full Text Available INTRODUCTION: Head trauma is an important consequence of child abuse. Specific pathophysiological mechanisms in child abuse are responsible for the ''whiplash shaken-baby syndrome'', which would favour the occurrence of intracranial hemorrhages. CASE REPORT: We report the case of a child who developed epidural hematoma following minor-intensity head trauma. Initial diagnosis of child abuse was made, but subsequent investigation led to the diagnosis of hemophilia A. CONCLUSION: Even though epidural hematoma is not closely associated with child abuse, this aethiology must always be considered when the reported trauma mechanism is out of proportion to the magnitude of the encountered lesions.INTRODUÇÃO: Traumatismo crânio-encefálico é importante conseqüência de abuso infantil. Mecanismos fisiopatológicos específicos do abuso infantil são responsáveis pela ''whiplash shaken-baby syndrome'', o que favoreceria o aparecimento de hemorragias intracranianas. RELATO DE CASO: Relatamos o caso de uma criança que desenvolveu hematoma extradural após trauma de pequena intensidade. Foi feito diagnóstico inicial de abuso infantil, mas investigações subseqüentes levaram ao diagnóstico de hemofilia A. CONCLUSÃO: Embora o hematoma extradural não esteja intimamente relacionado com abuso infantil, esta etiologia deve ser sempre considerada quando o mecanismo de trauma relatado estiver fora de proporção com as lesões encontradas.

    Extracellular matrix (ECM) remodeling increases the vulnerability to atrial fibrillation (AF). Some gene expressions are crucial for the metabolism of ECM. The left atrium plays an important role in maintaining AF.However, most studies investigated only the right atrial tissue. We therefore chose human tissue samples from both the left and right atrial to detect the different gene expressions during structural remodeling in AF. The atrial appendages tissue samples from 24 patients with chronic AF and 12 patients with sinus rhythm were obtained when they were undergoing mitral/aortic valve replacement operation. The mRNA levels of matrix metalloproteinases-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), disintegrin, metalloproteases-15, and integrins β1 were determined by reverse transcriptionpolymerase chain reaction (RT-PCR). in AF group, the level of MMP-9 in left atrial appendage (LAA) was increased (P<0.001), while integrin β1 level was decreased (P< 0.05) compared with those expressed in right atrial appendage (RAA) tissue. The levels of disintegrin, metalloproteinases-15, and TIMP-1 genes in the LAA and RAA had no significant differences. The results demonstrated that the gene expressions in the LAA and RAA are different during AF, which implied that the mechanism of atrial structural remodeling in AF is due to multiple sources and is complicated.

    Impact trauma may cause a hematoma, which is the leakage of venous blood into surrounding tissues. Large hematomas can be dangerous as they may inhibit local blood ow. Hematomas are often diagnosed visually, which may be problematic if the hematoma leaks deeper than the visible penetration depth. Furthermore, vascular wound healing is often monitored at home without the aid of a clinician. We therefore investigated the use of near infrared (NIR) re ectance photoplethysmographic imaging (PPGI) to assess vascular damage resulting from a hematoma, and monitor the healing process. In this case study, the participant experienced internal vascular damage in the form of a hematoma. Using a PPGI system with dual-mode temporally coded illumination for ambient-agnostic data acquisition and mounted optical elements, the tissue was illuminated with a spatially uniform irradiance pattern of 850 nm wavelength light for increased tissue penetration and high oxy-to-deoxyhemoglobin absorption ratio. Initial and follow-up PPGI data collection was performed to assess vascular damage and healing. The tissue PPGI sequences were spectrally analyzed, producing spectral maps of the tissue area. Experimental results show that spatial differences in spectral information can be observed around the damaged area. In particular, the damaged site exhibited lower pulsatility than the surrounding healthy tissue. This pulsatility was largely restored in the follow-up data, suggesting that the tissue had undergone vascular healing. These results indicate that hematomas can be assessed and monitored in a non-contact visual manner, and suggests that PPGI can be used for tissue health assessment, with potential extensions to peripheral vascular disease.

    Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. It places an enormous burden on the patients, caregivers, and the society at large. While the main themes in the care of an AF patient have not changed over the years and continue to focus on stroke prevention, control of the ventricular, rate and rhythm maintenance, there have been a number of new developments in each of these realms. This paper will discuss the “hot” topics in AF in 2012 including new and upcoming med...

    Full Text Available "Ball valve thrombus" which is a spherical free floating clot in left atrium is an often quoted, but uncommonly encountered complication in patients with severe mitral stenosis of rheumatic origin, who are in atrial fibrillation. We describe the case of a 31-year-old lady with rheumatic heart disease, severe mitral stenosis and moderately severe aortic stenosis who had undergone closed mitral valvotomy 13 years ago. The patient presented with an episode of non-exertional syncope and breathlessness on exertion of 6 months duration and was in normal sinus rhythm. Echocardiography facilitated ante-mortem diagnosis and prompt institution of surgery was life saving.

    Full Text Available OBJECTIVE: Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. METHODS: We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen Co., LTD, Guangdong, China utilizing standard techniques. RESULTS: Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology. CONCLUSION: Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective.

    Core-needle biopsy remains essential for diagnosis of cirrhosis; however, evaluation of fibrosis in such biopsies is often challenging due to the fragmented nature of cirrhotic liver specimens. It is also common to see portions of liver capsules present in the biopsy which adds to the diagnostic challenge. The distinction between capsular/subcapsular fibrous tissue and septal fibrosis is critical to avoid potential overstaging of liver fibrosis. We compared the differential immunostaining in liver capsular and septal areas for collagens III, IV, V, VI, vitronectin, laminin, Orcein, and Trichrome in 15 whole sections of explanted cirrhotic livers and 5 simulated liver biopsies. Collagens III, IV, V, VI, Trichrome, and Orcein show distinct staining patterns in capsular fibrous tissue and septal fibrosis. Collagen IV shows strong diffuse septal staining and consistently weak to negative capsular staining. Collagens III and VI stain similar to IV for septal fibrosis, whereas collagen V, Trichrome, and Orcein show strong staining in both areas. Collagen IV, possibly with III or VI in addition to the routine Trichrome and hematoxylin and eosin stain, is useful in differentiating capsular fibrous tissue from septal fibrosis on challenging and fragmented liver biopsies.

  6. Reward contingency modulates neuronal activity in rat septal nuclei during elemental and configural association tasks

    Full Text Available It has been suggested that septal nuclei are important in the control of behavior during various reward and non-reward situations. In the present study, neuronal activity was recorded from rat septal nuclei during discrimination of conditioned sensory stimuli (CSs of the medial forebrain bundle associated with or without a reward (sucrose solution or intracranial self-stimulation, ICSS. Rats were trained to lick a spout protruding close to the mouth just after a CS to obtain a reward stimulus. The CSs included both elemental and configural stimuli. In the configural condition, the reward contingency of the stimuli presented together was opposite to that of each elemental stimulus presented alone, although the same sensory stimuli were involved. Of the 72 responsive septal neurons, 18 responded selectively to the CSs predicting reward (CS+-related, four to the CSs predicting nonreward (CS0-related, nine to some CSs predicting reward or nonreward, and 15 nondifferentially to all CSs. The remaining 26 neurons responded mainly during the ingestion/ICSS phase. A multivariate analysis of the septal neuronal responses to elemental and configural stimuli indicated that septal neurons encoded the CSs based on reward contingency, regardless of the stimulus physical properties and were categorized into three groups; CSs predicting the sucrose solution, CSs predicting a nonreward, and CSs predicting ICSS. The results suggest that septal nuclei are deeply involved in discriminating the reward contingency of environmental stimuli to manifest appropriate behaviors in response to changing stimuli.

    Full Text Available The main alternative therapeutic strategies for acute atrial fibrillation are rate versus rhythm control. A major concern in cardioversion of newly detected atrial fibrillation is the risk of thromboembolic events. The vast majority of these events occur in the first week following cardioversion. Transesophageal echocardiography has demonstrated that thrombus and dense spontaneous echo contrast may occur in the left atrium and left atrial appendage also in patients with acute atrial fibrillation (<48 hours scheduled for cardioversion. Moreover, atrial function may become impaired immediately following successful cardioversion. Thus, the current North American and European guidelines recommend that patients with acute atrial fibrillation should undergo cardioversion under cover of unfractionated or low-molecular weight heparin followed by oral anticoagulation for at least 4 weeks in patients in patients at moderate-to-high risk for stroke. In line with the guidelines, new evidence from a large patient population suggests that after successful cardioversion of acute atrial fibrillation, patients have a low overall risk of thromboembolic events without any anticoagulation when they have no risk factors for thromboembolism. In contrast, the risk is in the range of 10% in patients with multiple classic risk factors for thromboembolism.

    Atrial fibrillation (AFib) is a common clinical entity, responsible for significant morbidity and mortality, but it also accounts for a large percentage of healthcare dollar expenditures. Efforts to treat this arrhythmia in the past have focused on subacute antithrombotic therapy and eventually use of antiarrhythmic drugs for maintenance of sinus rhythm. However, there has been a growing interest in the concept of acute electrical and pharmacologic conversion. This treatment strategy has a number of benefits, including immediate alleviation of patient symptoms, avoidance of antithrombotic therapy, and prevention of electrophysiologic remodeling, which is thought to contribute to the perpetuation of the arrhythmia. There is also increasing evidence that this is a cost-effective strategy in that it may obviate admission to the hospital and the cost of long-term therapy. This article represents a summary of the treatments that may be used acutely to control the ventricular response to AFib, prevent thromboembolic events, and provide for acute conversion either pharmacologically or electrically. It includes information on modalities that are currently available and those that are under active development. We anticipate that an active, acute treatment approach to AFib and atrial flutter will become the therapeutic norm in the next few years, especially as the benefits of these interventions are demonstrated in clinical trials.

    Objective Mechanisms of pulmonary vein isolation (PVI) for atrial fibrillation remain controversy.This study aimed to investigate the impact of PVI on vagal modulation to atria.Methods Eighteen adult mongrel dogs under general anesthesia were randomly divided into two groups.Bilateral cervical sympathovagal trunks were decentralized and sympathetic effects was blocked by metoprolol administration.Atrial electrical remodeling (AER) was established by rapid right atrial pacing at the rate of 600 bpm for 30 minutes.PVI was performed in group A.Atrial effective refractory period (ERP),vulnerability window (VW) of atrial fibrillation,and sinus rhythm cycle length (SCL) were measured at baseline and during vagal stimulation before and after atrial rapid pacing with and without PVI at fight atrial appendage (RAA),left atrial appendage (LAA),distal coronary sinus (CSd) and proximal coronary sinus (CSp).Results (1) Effects of PVI on vagal modulation:Shortening of SCL during vagal stimulation decreased significantly after PVI compared with that before PVI in group A (P<0.001).Shortening of ERP during vagal stimulation decreaseed significantly after PVI compared with that before PVI (P<0.05).VW of atrial fibrillation during vagal stimulation decreased significantly after PVI compared with that before PVI (P<0.05).(2) Effects of PVI on AER:shortening of ERP before and after atrial rapid pacing increased significantly at baseline and vagal stimulation in group B compared with that in group A (P<0.05).VW during vagal stimulation increased significantly after atrial rapid pacing in group B (P<0.05).Conclusion PVI attenuates the vagal modulation to the atria,thereby decreases the susceptibility to atrial fibrillation mediated by vagal activity.PVI releases AER,which maybe contributes to the vagal denervation.Our study indicates that PVI not only can eradicate triggered foci but also modify substrates for AF.(J Geriatr Cardiol 2008;5:28-32)

    Amniotic fluid 'sludge' is defined as the presence of dense aggregates of particulate matter in close proximity to the internal cervical os. It is of clinical significance in asymptomatic patients at high risk for spontaneous delivery, and in patients with preterm labor and intact membranes. Subchorionic hematoma is another ultrasound finding that is associated with a higher incidence of threatened miscarriage and preterm delivery. We report two cases of occurrence of amniotic fluid sludge in patients with previously detected large subchorionic hematoma. In the first case subchorionic hematoma and amniotic fluid sludge were detected by ultrasonography at 13 + 1 and 18 + 6 weeks' gestation, respectively, followed by preterm premature rupture of membranes, placental abruption and emergency Cesarean section. In the second case subchorionic hematoma and amniotic fluid sludge were detected by ultrasound at 11 + 3 and 15 + 5 weeks' gestation, respectively, followed by miscarriage with histological chorioamnionitis. The coincidence of subchorionic hematoma and amniotic fluid sludge in these cases points to a possible connection between these two significant ultrasound findings. PMID:19308930

    Full Text Available Abstract Abdominal wall hematoma is a rare and life-threatening complication after carotid artery stenting (CAS, but it can occur when activated clotting time is prolonged. We report a right lateral abdominal wall hematoma caused by rupture of the superficial circumflex iliac artery after CAS in a 72-year-old man with severe stenosis of the origin of the right internal carotid artery. We performed CAS for the targeted lesion while activated clotting time exceeded 300 seconds. After 2 hours, he complained of right lateral abdominal pain. Abdominal computed tomography revealed an extensive hematoma in the right lateral abdominal wall. Activated clotting time was 180 seconds at this point. Seven hours later, he developed hypotension and hemoglobin level dropped to 11.3 g/dl. Subsequent computed tomography showed enlargement of the hematoma. Emergent selective angiography of the external iliac artery revealed active bleeding from the right superficial circumflex iliac artery. Transcatheter arterial embolization with Gelfoam and microcoils was performed successfully. With more CAS procedures being performed, it is important for endovascular surgeons and radiologists to consider the possibility of abdominal wall hematoma in this situation.

  14. Development and clinical usefulness of stereotactic endoneurosurgical system for intracerebral hematoma

    International Nuclear Information System (INIS)

    Since computed tomography (CT)-guided stereotactic surgery is essentially blind surgery, it always involves the risk of injuring viable brain tissue and vessels. Thus, we have developed a new endoneurosurgical system for stereotactic brain surgery. This system consists of a neuroendoscope made of a Selfoc long rod-shaped deflective distribution lens 1.0 mm in diameter, a special ultrasonic aspirator for fragmentation and aspiration of hard blood clots, a micromanipulator and a specially designed stereotactic attachment device, so that they can be accurately inserted into the optimun position from any direction. We have applied this stereotactic endoneurosurgical system to 30 cases of intracerebral hematoma comprising 12 putaminal, 11 thalamic, 4 subcortical, 2 brain stem, 1 cerebellar hemorrhage. The mean age was 65 years old, 79% of patients were over 60 years old, mean hematoma volume was 22 ml, mean rate of removal was 85%, and there was no intraoperative or postoperative hemorrhage. During removal of an intracerebral hematoma, intraoperative bleeding was prevented by the direct observation of microvessels in the wall of the hematoma cavity. This system was developed to allow application of stereotactic techniques to endoscopic surgery. The stereotactic endoneurosurgery is considered to be less invasive, safer, and more accurate, as it can be applied to removal of intracerebral hematoma. (author)

    A 72-year-old female presented with a unique case of acoustic neurinoma with a cystic component followed by the chronic subdural hematoma manifesting as trigeminal neuralgia, facial palsy and trunchal ataxia 7 months after gamma knife radiosurgery. Magnetic resonance imaging demonstrated a loss of central contrast enhancement at the postoperative residual tumor mass and a large cyst associated with a hematoma in the subdural space. A right suboccipital craniectomy was performed. A biopsy of the mass and the membrane was performed following aspiration of the brown-reddish fluid collection. The histological diagnosis was acoustic neurinoma with a hemorrhagic necrosis. The membranous tissue mimicked an outer membrane obtained from chronic subdural hematoma. The postoperative course was satisfactory and preoperative symptom have been alleviated. In this case, the chronic subdural hematoma occurred at posterior fossa during the development of cysts caused by the radiosurgery, because the subdural space had been connected with the subarachnoid space after the first operation. The development of cysts or hematoma should be taken into consideration as possible complications following treatment with gamma knife radiosurgery for acoustic neurinomas. (author)

    A rare case of acute epidural hematoma of the posterior fossa associated with von Willebrand's disease is reported. A 9-year-old boy fell down and hit his occipital region against a floor. Soon after he came home and slept, but three hours later he began to vomit and became drowsiness. He visited our hospital and his Glasgow Coma Scale showed 13 points. CT scan on admission showed acute epidural hematoma of left posterior fossa and contusional hematoma in the right temporal lobe. The bleeding time was over 18 minutes. He had been suspected to be suffering from von Willebrand's disease two years ago. Then fresh blood, fresh frozen plasma and anti-hemophilic globulin were prepared. Ten hours after injury, the operation was begun. Fresh epidural hematoma existed as a clot beyond transverse sinus. During the procedure of dural tenting suture, diffuse bleeding from bone, muscle, subcutaneous tissue and dura occurred and it was difficult to stop the bleeding. By using fresh blood and anti-hemophilic globulin, the bleeding was controlled, and then the operation was achieved. In the postoperative course a new epidural hematoma was found in the left temporal region and a new but asymptomatic retinal hemorrhage was found in his right eye. He was discharged without any neurological deficits 25 days after operation.

    Full Text Available Abstract Introduction Postoperative spinal extradural hematomas are rare. Most of the cases that have been reported occured within 3 days of surgery. Their occurrence in a delayed form, that is, more than 72 hours after surgery, is very rare. This case is being reported to enhance awareness of delayed postoperative spinal extradural hematomas. Case presentation We report a case of acute onset dorsal spinal extradural hematoma from a paraspinal muscular arterial bleed, producing paraplegia 72 hours following surgery for excision of a spinal cord tumor at T8 level. The triggering mechanism was an episode of violent twisting movement by the patient. Fresh blood in the postoperative drain tube provided suspicion of this complication. Emergency evacuation of the clot helped in regaining normal motor and sensory function. The need to avoid straining of the paraspinal muscles in the postoperative period is emphasized. Conclusion Most cases of postoperative spinal extradural hematomas occur as a result of venous bleeding. However, an arterial source of bleeding from paraspinal muscular branches causing extradural hematoma and subsequent neurological deficit is underreported. Undue straining of paraspinal muscles in the postoperative period after major spinal surgery should be avoided for at least a few days.

    The totally thoracoscopic left atrial maze (TT-maze) is a recent, minimally invasive surgical procedure for the treatment of atrial fibrillation, with promising results in terms of freedom from atrial fibrillation. The TT-maze consists of a bilateral, epicardial pulmonary vein isolation with the creation of a box using radiofrequency and exclusion of the left atrial appendage (LAA). In addition, the box is connected with the base of the LAA and furthermore with the mitral annulus with the so-called trigonum line. In this report, we describe our surgical approach and short-term results. PMID:26993056

    Two cases of fetal tachycardia are reported: atrial flutter and fibrillation. The waveforms from each case were detected by fetal magnetocardiograms (FMCGs) using a 64-channel superconducting quantum interference device (SQUID) system. Because the magnitude of supraventricular arrhythmia signals is very weak, two subtraction methods were used to detect the fetal MCG waveforms: subtraction of the maternal MCG signal, and subtraction of the fetal ORS complex signal. It was found that atrial-flutter waveforms showed a cyclic pattern and that atrial-fibrillation waveforms showed f-waves with a random atrial rhythm. Fast Fourier transform analysis determined the main frequency of the atrial flutter to be about 7Hz, and the frequency distribution of atrial fibrillation consisted of small, broad peaks. To visualise the current pattern, current-arrow maps, which simplify the observation of pseudo-current patterns in fetal hearts, of the averaged atrial flutter and fibrillation waveforms were produced. The map of the atrial flutter had a circular pattern, indicating a re-entry circuit, and the map of the atrial fibrillation indicated one wavelet, which was produced by a micro-re-entry circuit. It is thus concluded that an FMCG can detect supraventricular arrhythmia, which can be characterised by re-entry circuits, in fetuses. PMID:12043803
