    A 26-year-old female diabetic patient developed hypertensive encephalopathy with gross neurological abnormalities complicating renal artery stenosis of her transplant kidney. The elevated blood pressure was unresponsive to medical treatment. Surgical correction of the stenoses in the renal artery cured the hypertension and renal failure and led to the patient's complete recovery.

  3. Arterial Complications of Percutaneous Transhepatic Biliary Drainage

    International Nuclear Information System (INIS)

    Purpose: To report on the frequency and treatment of arterial complications due to percutaneous transhepatic biliary drainage (PTBD).Materials: Lesions of the intrahepatic artery were encountered in 10 of 525 patients treated by PTBD (2%). Hemobilia followed in 9 patients and subcapsular hematoma in 1. Seven patients had a benign biliary stenosis and 3 had a malignant stenosis.Results: The bleeding resolved spontaneously in 3 patients. In 7 it required arterial embolization, which was successfully achieved either through the percutaneous catheter (n= 3) or by arteriography (n= 4).Conclusion: Arterial bleeding is a relatively rare complication of PTBD that can easily be treated by selective arterial embolization when it does not resolve spontaneously. In this series its frequency was much higher (16%) when the stenosis was benign than when it was malignant (0.6%)

    The natural history of pseudoaneurysms complicating pancreatitis is unknown. A patient with chronic pancreatitis is described in whom thrombosis of a splenic artery pseudoaneurysm occurred. Early diagnosis and radical treatment of a bleeding pseudoaneurysm are mandatory. When elective treatment is considered, however, contrast enhanced computed tomography may be useful just before surgery as thrombosis may occur.

    Full Text Available INTRODUCTION: Renal transplantation with multiple arteries appears, in literature, associated to a major index of surgical complications. This study compared the surgical complications and short-term outcome renal transplants with multiple arteries and single artery grafts. MATERIALS AND METHODS: The data of 64 renal transplants with multiple arteries performed between January 1995 and December 1999 were compared to the ones of 292 transplants with single renal artery. The aspects analyzed were number of arteries of the graft, donor type, vascular reconstruction technique, the occurrence of surgical complications, the incidence of delayed graft function, graft function 1 month after transplantation, graft loss and the patients' deaths. RESULTS: The incidence of surgical complications in grafts with multiple arteries and single renal artery was respectively: vascular - 3.1% and 3.1%; urological - 6.3% and 2.7% and other surgical complications - 15.6% and 10.6%, respectively. The incidence of lymphoceles was 3.1% in grafts with a single artery and 12.5% in grafts with more than 1 artery (p = 0.0015. The incidence of delayed graft function in grafts with multiple arteries and with a single renal artery was respectively 35.1 and 29.1% (p = 0.295. Mean serum creatinine at the 30th postoperative day was 2.46 and 1.81 in grafts with multiple and with 1 artery, respectively (p=0.271. CONCLUSIONS: Kidney transplantation using grafts with single and multiple arteries present similar indexes of surgical complications and short-term outcome; lymphoceles were more frequent among grafts with multiple arteries.

    2015-10-01

    The most serious complication of carotid artery stenting (CAS) is acute carotid artery stent thrombosis (ACAST). ACAST is a very rare complication, but it may lead to dramatic and catastrophic consequences. The most important cause is inadequate or ineffective antiaggregant therapy. It is very important to identify, before CAS, those patients who might be candidates for ACAST and to start antiplatelet therapy for them. Testing patients who are candidates for CAS for acetylsalicylic acid and clopidogrel resistance may prevent this complication. PMID:26303788

    1996-01-01

    Over a period of 5 years 81 vascular complications after 15,460 catheterizations of the femoral artery for diagnostic (n = 11,883) or therapeutic (n = 3577) procedures were registered. The following complications were observed in declining frequency: 1. False aneurysm (n = 65), 2. arterial occlusion (dissection, embolia, thrombosis) (n = 8), 3. vascular lesion causing profuse bleeding (n = 7), 4. AV-fistula (n = 1). The total complication rate was 0.52%. The complication rate was significantly higher in therapeutical procedures (1,03%) than in diagnostic investigations (0.37%). Pseudoaneurysms were complicated by thrombosis of the femoral vein (n = 3), lymphatic fistula (n = 3) and deep wound infection (n = 9); secondary complication rate 18.5%. Risk factors for local vascular complications are old age, female gender, high grade arteriosclerosis at the puncture site, overweight, manifest arterial hypertension and medication with cumarin, acetylsalicylic acid or heparin. Further complicating factors are connected with technical risks such as duration of the procedure. French size of the catheter, the catheter sheath and multiple punctures. Vascular repair was performed by simple angiography in most cases, but in 14.8% more extensive surgical procedures were required. In patients with signs of occlusive vascular disease the external iliac artery was replaced by a PTFE-vascular access graft in 4 cases and an arterioplasty of the deep femoral artery was performed in 2 patients. 36% of the operations were undertaken as emergencies. Reintervention was necessary for a postoperative bleeding complication in 1 case (surgical complication rate 1.2%). A female patient suffering from aortic valve stenosis died during emergency operation due to massive retroperitoneal hemorrhage after cardiac catheterization (mortality rate 1.2%). Over a median follow-up period of 37 months no late complications of the intervention were recorded, nor recurrences of peripheral arterial occlusive

  10. Interventional therapy of complications after liver transplantation: arterial steal syndrome

    International Nuclear Information System (INIS)

    Arterial steal syndrome (ASS), a scarce complication after liver transplantation, is characterized by hepatic arterial hypoperfusion of the graft caused by a shifting of blood flow into the splenic, left gastric, or gastroduodenal arteries. It can lead to stricture formation of biliary system and transplanted liver function exhaustion. The early diagnosis and treatment are important for protecting the transplanted liver function. Dynamic CDFI after liver transplantation as a routine is necessary to find out the suspected lesions, and transcatheter angiography as the gold standardization can give clear dignosis. Embolization of splenic artery is minimally invasive, successful and less complication treatment for ASS and especially the coil embolization of middle segment of splenic artery is the best choice.

  11. Transcatheter arterial embolization - major complications and their prevention

    International Nuclear Information System (INIS)

    A thorough account is given of the complications of embolization techniques in nonneurovascular areas, including hepatic infarction, renal and splenic abscess formation. Infarction of the urinary bladder, gallbladder, stomach, and bowel are discussed. Suggestions are offered to prevent complications from embolization where possible. Specific agents for embolization are detailed and their relative merits are compared; ethyl alcohol has recently gained popularity for treating esophageal varices and infarcting renal tumors. Care is advocated when using alcohol in the renal arteries; employing this agent is currently contraindicated in the celiac and mesenteric arteries. Coils and balloon systems are also described along with their potential complications. (orig.)

  12. Inferior phrenic artery pseudoaneurysm complicating drug-induced acute pancreatitis.

    Salem, Jean F; Haydar, Ali; Hallal, Ali

    2014-01-01

    Inferior phrenic artery (IPA) pseudoaneurysm is an extremely rare complication of chronic pancreatitis with only three cases reported in the literature so far. It is a serious condition that can be life-threatening if not diagnosed promptly. Recent advances in endovascular interventions made angiography with embolisation the modality of choice for diagnosis and treatment. We presented the first report of a case of ruptured IPA pseudoaneurysm complicating a drug-induced acute pancreatitis that was successfully treated by transcatheter arterial embolisation. Despite its rarity, rupture of pseudoaneurysm due to drug-induced pancreatitis should be suspected and included in the differential diagnosis when associated with haemodynamic instability.

    Reiter, D.; Piccone, B.R.; Littman, P.; Lisker, S.A.

    1979-03-01

    Tracheoinnominate artery fistulization is a well-known complication of tracheostomy and of tracheal resection. The first known occurrence of this problem in a patient in whom no transtracheal procedure had ever been performed is reported, and high-dose radiation therapy delivered three years before for a mediastinal malignancy is suggested as the cause. No evidence of tumor was found in or adjacent to the tracheovascular communication. The tracheoinnominate artery fistula must be considered a potential complication of radiation therapy as well as of surgery.

  14. Interventional therapy of complications after liver transplantation: hepatic artery stricture

    International Nuclear Information System (INIS)

    Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods. (authors)

  15. Severe complications associated with transcatheter hepatic arterial chemoembolization

    International Nuclear Information System (INIS)

    Transcatheter hepatic arterial chemoembolization (THACE) has been widely used in the treatment of advanced primary hepatic carcinoma (PHC)and metastatic hepatic carcinoma (MHC). Although the incidence of severe complications associated with THACE is unusual (0%-5%), its prognosis is generally worse and mortality is higher than that of postemholization syndrome. Therefore, to minimize the risk associated with THACE has to be achieved through the understanding of these severe complications related to the selection of indication,the use of chemoembolic agents and manipulation ora cathether or guide wire, etc. In this paper, according to the involved anatomic organs, these severe complications are divided into six categories as follows: (1)complications of the liver, including acute hepatic failure, liver infarction (necrosis), liver abcess and liver (or tumor)ruptrure; (2)complications of the celiac artery and its branches, included of iatrogenic dissection, stricture or occlusion, perforation or pseudoaneurysm and multiple intrahepatic aneurysms; (3)complications of intrahepatic biliary system, included of cholecystitis and gallbladder infarction, bile duct necrosis and intrahepatic biloma formation; (4)complications of extrahepatic structures, included of nontarget embolism or infarction of the brain, spinal cord, lung, spleen, gastroduodenum and pancreas; (5)bleeding of upper digestive tract; (6)the orthers. And the incidence, pathogenesis, predisposing factors, clinical and imaging manifestations of these complications are also discussed in detail, it may be of great advantage to its correct diagnosis promptly and appropriate management.

    Full Text Available Snakebites are endemic in some parts of India, being associated with a number of complications. Ocular disturbances are rare, except for injury to the cornea or conjunctiva when the eye is directly exposed to the venom. In this work, we present a case of central retinal artery occlusion caused by snakebite.

  17. Interventional therapy of complications after liver transplantation: hepatic artery thombosis

    International Nuclear Information System (INIS)

    Resolution of the complications after liver transplantation is one of the important factors related to prognosis. Hepatic artery thombosis (HAT) after liver transplantation can lead directly to trans- planted liver undergone necrosis, biloma formation and liver functional exhaustion. The early diagnosis with Color Doppler which should be the first method of choice, CTA, MRA and angiography could lead to exact demonstration, and proper treatment can result in better prognosis. The microinvasive techniques such as local thrombolysis, balloon dilatation and stent placement are safe and effective for treatment of hepatic artery thombosis. The vascular reconstruction and oxygen hyperbaric are effective therapeutic methods. Repeat liver transplantation is still the last important choice for survival. (authors)

    A 78-year-old man presented with a 7-cm aneurysm in the left superficial femoral artery, which was considered unfit and anatomically unsuitable for conventional open surgery for multiple comorbidities. The patient was treated with stent-graft [Viabhan stent-graft (WL Gore and Associates, Flagstaff, AZ)]. Two years from stent-graft implantation, the patient presented a purulent secretion and a spontaneous external expulsion through a fistulous channel. No claudication symptoms or hemorrhagic signs were present. The pus and device cultures were positive for Staphylococcus aureus sensitive to piperacillin/tazobactam. Patient management consisted of fistula drainage, systemic antibiotic therapy, and daily wound dressing. At 1-month follow-up, the wound was closed. To our knowledge, this is the first case of this type of stent-graft complication presenting with external expulsion.

    International Nuclear Information System (INIS)

    Objectives: To evaluate incidence of local complications of radial artery (RA) harvesting for coronary art-ery bypass grafting (CABG). Patients and Methods: From March 2011 to January 2012, a total of 87 consecutive patients fulfilling the inclusion and exclusion criteria, who underwent CA-BG and had left radial artery used as a conduit were included in this study. Prospective surveillance of surgical site (radial artery harvest site) was assessed on a daily basis during the patient's stay in the Department of Cardiac Surgery, Mayo Hospital / KEMU, Lahore and were reassessed after one month and six months interval. Surgical site assessment includes cutaneous paraesthesia, compartment syndrome, hand Ischemia, donor arm weakness, superficial infection, wound dehiscence, hematoma and impact of these complications on the quality of life. Results: During the study period 6 Patients (6.8%) reported cutaneous paraesthesia around the thenar eminence after 6 months; 3 Patients (3.4%) developed donor arm weakness, normalized after 6 months. Superficial wound infection and Hematoma (not requiring re-exploration) was noted in 1.1% and 2.9% respectively. None of the patients developed compartment syndrome, hand Ischemia, wound dehiscence. Conclusions: Findings confirm that the local complications after radial artery harvesting are rare and are clinically insignificant. (author)

    Full Text Available Introduction. Pancreatic pseudocyst presented as pseudoaneurysm of the splenic artery is a potential serious complication in patients with chronic pancreatitis. Case report. A 42-year-old male patient with a long-standing evolution of chronic pancreatitis and 8-year long evolution of pancreas pseudocyst was referred to the Military Medical Academy, Belgrade due to worsening of the general condition. At admission, the patient was cachectic, febrile, and had the increased values of amylases in urine and sedimentation (SE. After clinical and diagnostic examination: laboratory assessment, esophagogastroduodenoscopy (EGDS, ultrasonography (US, endoscopic ultrasonography (EUS, multislice computed scanner (MSCT angiography, pseudoaneurysm was found caused by the conversion of pseudocyst on the basis of chronic pancreatitis. The patient was operated on after founding pancreatic pseudocyst, which caused erosion of the splenic artery and their mutual communication. Postoperative course was duly preceded without complications with one year follow-up. Conclusion. Angiography is the most reliable and the safest method for diagnosing hemorrhagic pseudocysts when they clinically present as pseudoaneurysms. A potentially dangerous complication in the presented case was treated surgically with excellent postoperative results.

    Bleeding complications of dengue hemorrhagic fever such as epistaxis, gum bleeding, gastrointestinal bleeding, hypermenorrhea, hematuria, and thrombocytopenia have been documented. A 49-year-old female presented with complaints of intermittent high-grade fever for the past 4 days, lower abdominal pain and altered sensorium for 1 day. Laboratory investigations revealed severe anemia, mild thrombocytopenia, hypofibrinogenemia, and positive dengue serology. Emergency ultrasound examination of the abdomen revealed a possible rapidly expanding hematoma from the inferior epigastric artery and suggested urgent computed tomography (CT) angiogram for confirmation of the same. CT angiogram was confirmatory, and patient underwent emergency embolization of the right inferior epigastric artery. We report the first case of inferior epigastric hemorrhage and rectus sheath hematoma as a consequence of dengue.

  6. Endovascular treatment of acute arterial complications after living-donor liver transplantation

    International Nuclear Information System (INIS)

    Aim: The aim of this study was to evaluate the efficacy of endovascular treatment for acute arterial complications following living-donor liver transplantation (LDLT). Materials and methods: Of 79 LDLT patients, 17 (mean age 48 ± 8 years, range 33-66 years) who had acute arterial complications and underwent endovascular treatment were evaluated. Transcatheter arterial embolization was performed to control peritoneal bleeding. Catheter-directed thrombolysis using urokinase was performed in hepatic artery thromboses. The locations of complications and materials used were evaluated. The technical and clinical success rates were calculated. Results: Twenty-three acute arterial complications, including four hepatic artery thromboses and 19 cases of peritoneal haemorrhages were identified in 22 angiographic sessions in 17 patients. The mean duration between LDLT and first angiography was 3.2 ± 3.5 days (range 1-13 days). Hepatic artery recanalization with catheter-directed thrombolysis using urokinase was achieved in two patients. Transcatheter arterial embolization for peritoneal bleeding was successfully performed in 16 cases. The most common bleeding focus was the right inferior phrenic artery. Additional surgical management was needed in five patients to control bleeding or hepatic artery recanalization. Technical and clinical success rates of transcatheter arterial embolization were 84.2 and 63.1%, respectively. Overall technical success was achieved in 18 of 23 arterial complications (78.2%), and clinical success was achieved in 14 of 23 arterial complications (60.8%). Conclusion: Endovascular treatment for the acute arterial complications of haemorrhage or thrombosis in LDLT patients is safe and effective. Therefore, it should be considered as the first line of treatment in selective cases

  8. Treatment of complex internal carotid artery aneurysms using radial artery grafts. Surgical technique, perioperative complications, and results in 17 patients

    International Nuclear Information System (INIS)

    Complex giant or large internal carotid artery aneurysms present a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict the occurrence of ischemic complications after internal carotid artery ligation. The present study concerns surgical technique, complications, and clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2005, we performed radial artery grafting followed immediately by parent artery occlusion in 17 patients with giant or large complex intracranial carotid aneurysms (3 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative digital subtraction angiography to assess graft patency and aneurysm obliteration. All 17 aneurysms were excluded from the cerebral circulation, with all radial artery grafts patent. Among 4 patients with cranial nerve disturbances, dysfunction was temporary in 5; in the others, oculomotor nerve paresis persisted. No perioperative cerebral infarction occurred. Sensory aphasia reflecting cerebral contusions caused by temporal lobe retraction resolved within 2 months, as did hemiparesis from a postoperative epidural hematoma. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Graft patency and aneurysm thrombosis were achieved in all patients. Cranial nerve dysfunction (III, VI) caused by altered blood flow from the internal carotid artery after occlusion was the most common complication and typically was temporary. In our experience with these difficult aneurysms, not only clipping but also reconstruction of the internal carotid artery was required, especially for wide-necked symptomatic

    Surgical treatment of varicose veins occasionally can be followed by severe limb ischemia either after surgery or sclerotherapy. We report here two cases with the clinical features and the therapeutic strategy. The first case concerned a woman operated by venous stripping. A post-operative acute ischemia occurred and was treated by femoro-femoral bypass and lumbar sympathectomy. However this procedure did not avoid persistent chronic ischemia, sciatica paralysis and equinus ankle blockage. A secondary arterial procedure associated with intensive physiotherapy and ankle arthrodesis led to a poor functional result, partly because of an irreversible algodystrophia. The second case concerned a woman treated by sclerotherapy. An injection of the drug in the retro-malleolar area was immediately followed by an acute foot ischemia. Heparin, xylocaine and sodium nitroprusside perfusion avoided a foot amputation, however osteoporosis and algodystrophia occurred. A sympathectomy was necessary two years later. These dramatic complications although unusual, may occur even with experienced physicians. Therefore a great attention is always necessary during these simple procedures. In case of acute ischemia, early diagnosis and aggressive treatment are necessary, but prevention remains more secure. PMID:3944517

    During a 3-year period, three patients developed arterial complications related to congenital or post-traumatic old pseudarthrosis of the clavicle. Arterial complications of pseudarthrosis of the clavicle presenting as a thoracic outlet syndrome are very rare. Symptoms are variable and occur late. Without treatment, the prognosis is poor with spontaneous development of gangrene. Arterial morphology investigations should be undertaken in patients with pseudarthrosis of the clavicle or isolated arterial symptoms involving the upper limb whose radial pulse disappears during postural tests. Duplex Doppler of the subclavian artery is an excellent screening exam but selective arteriography is the gold standard. It shows proximal arterial lesions (embolytic stenosis of the subclavian artery with post-stenotic dilatation), as well as distal embolic complications. Both static and postural tests must be performed to unmask subclavian restriction by the clavicle, proving its causal effect in the arterial complications. There are four clinical varieties: chronic thrombosis of the subclavian artery, distal arterial micro emboli, acute thrombosis of proximal arteries of the upper limb, and subclavian aneurysm. These lesions are thought to be due to chronic constriction and repeated arterial microtrauma. Congenital or post-traumatic pseudarthrosis, hypertrophic callus, arterial restriction by a screw in a clavicular plate, usually explain the arterial lesions. Bone tumors and Paget's disease are potential but exceptional clavicular etiologies. Surgical treatment is always necessary. Clavicular resection is usually needed in case of pseudarthrosis; there is no functional handicap. Plate fixation and autologous grafting, or open reduction and internal fixation are other valid surgical treatments; The embolytic lesions must be treated to prevent recurrence of distal embolization: graft resection and thromboendarteriectomy have been described.

    We report the case of a two-month-old immunocompetent girl affected by Staphylococcus aureus sepsis complicated with pneumonia and pleural effusion, spondylodiscitis and endophthalmitis treated with linezolid. She developed a S. aureus sepsis in the neonatal period antibiotically treated with clinical resolution. Ten days after therapy discontinuation, the infant experienced a new S. aureus sepsis complicated by pneumonia with pleural effusion. Due to the presence of dorsal swelling, a pulmonary computer tomography was performed that showed a dorsal D5-D6 spondylodiscitis. Since the sepsis was scarcely responsive to several appropriate antibiotics, we finally decided to treat the patient with linezolid. A few weeks after changing antibiotics, the child underwent an ophthalmologic visit. Due to the finding of ocular lesions, imaging examinations were performed. The diagnosis was compatible with retinoblastoma, such that the eye was enucleated. Nevertheless, histological and microbiological investigations did not confirm the tumour hypothesis, but revealed a S. aureus abscess with retinal detachment. The child completed antibiotic therapy with linezolid and was visited periodically at the Infectious Disease Unit for a follow-up. She underwent progressive resolution of discitis and did not present any further flare of sepsis. Nevertheless, she still has a replacement device in her right eye and a D5-D6 severe kyphosis with spinal fusion. PMID:26700087

    Iatrogenic injury of a lumbar artery is very rare and mostly causes retroperitoneal hemorrhage. We report a case of a lumbar artery pseudoaneurysm and a concomitant arteriovenous fistula complicating laparoscopic splenectomy and provoking renal colic-like flank pain due to mass effect on the left ureter. Definitive treatment of both vascular lesions was obtained after percutaneous transcatheter embolization of several lumbar arteries. Control computed tomography scan 3 months after embolization showed almost complete resorption of the retroperitoneal hematoma. (orig.)

  1. The application of interventional radiological procedures in treating hepatic artery complications occurred after liver transplantation

    International Nuclear Information System (INIS)

    Objective: To evaluate the interventional radiological procedures in treating hepatic artery complications occurred after liver transplantation. Methods: Thirteen patients with hepatic artery complications occurred after liver transplantation received interventional treatment. The interventional procedures included (1) percutaneous transarterial angioplasty (PTA) or endovascular stenting (ES) for 6 patients with hepatic artery stenosis (HAS) and for 3 patients with hepatic artery occlusion; (2) catheter-directed thrombolysis for 3 patients with hepatic artery thrombosis (HAT) and (3) coil embolization for one patient with gastroduodenal steal syndrome (GSS). Immediate, short-term and long-term effects were observed and evaluated. Results: The general immediate effective rate was 84.62% (11/13). The effective rate was 100% for HAS (6/6), HAT (3/3) and GSS (1/1). However, the effective rate for hepatic artery occlusion was only 33.3% (1/3). Color Doppler ultrasonography showed that the hepatic arterial flow remained fluent. Three days after the treatment statistically significant decrease in ALT (t=2.68, P<0.050) and T-BIL (t=2.94, P<0.05) was observed. No procedure-related complications or death occurred during the follow-up period of 2-34 months. Conclusion: As a safe, effective and minimally-invasive technique, interventional management can be regarded as the treatment of first choice for hepatic artery complications occurred after liver transplantation.

    Ear, nose and throat infections are common, especially in children and young adults. Since the advent of antibiotics, complications from tonsillitis and pharyngeal abscess are rare, but potentially lethal. Vascular complications can be imaged with Doppler ultrasound and CT scan. The treatment of infectious vascular complications represents a significant challenge. We describe the case of a young girl presenting with a pseudoaneurysm of the internal carotid and thrombosis of the internal jugular vein. Endovascular therapy was utilized to treat the patient.

    Full Text Available Pseudoaneurysms of intercostal artery are very rare. All the published cases have been caused by trauma, either iatrogenic or otherwise. They can cause hemothorax, retroperitoneal hemorrhage or can present as pulsatile chest mass. Doppler ultrasound, contrast-enhanced CT and conventional angiogram can accurately diagnose this condition. All the reported cases have been treated by embolisation, stenting or surgery. We report an unusual case of intercostal artery pseudoaneurysm arising as a complication of corrosive poisoning presenting with hematemesis and treated by glue embolisation. The authors believe this to be the first case of intercostal artery pseudoaneurysm that is non-traumatic, complicating corrosive poisoning and presenting with hematemesis.

    International Nuclear Information System (INIS)

    One hundred and two patients, who were being evaluated for carotid artery disease, were prospectively studied for complications occurring as a result of intravenous digital subtraction angiography (DSA). The authors recorded the type, number, and outcome of complications and reviewed the amount of contrast material used, along with the patient's age and medical history for possible correlation with increased complications. There were 55 total complications or side effects involving 37 patients. Central nervous system (CNS) complications included six major-transient and one major-permanent complication. Systemic complications included 20 major-transient and two major-permanent events. Complications in our series were significantly higher than previous DSA reports and published data on conventional angiography studies. Many of our patients were in a relatively high risk group

    Brachial plexus injury is an unusual and under-recognised complication of coronary artery bypass grafting especially when internal mammary artery harvesting takes place. It is believed to be due to sternal retraction resulting in compression of the brachial plexus. Although the majority of cases are transient, there are cases where the injury is permanent and may have severe implications as illustrated in the accompanying case history.

  8. Skin complications caused by transcatheter hepatic arterial chemoembolization for malignant liver tumors

    International Nuclear Information System (INIS)

    Objective: to discuss the etiologic factors and the corresponding preventions of the skin and subcutaneous tissue complications which occurred after transcatheter hepatic arterial chemoembolization (TACE) for the treatment of malignant liver tumors. Methods: The clinical data of the patients with malignant liver tumors who received TACE during the period from April 2008 to April 2009 were retrospectively reviewed. The patients who developed skin complications after TACE were enrolled in this study. Results: In the period mentioned above, TACE was performed in a total of 1607 consecutive patients with malignant liver tumors. After TACE skin and subcutaneous tissue complications occurred in four patients only, the occurrence was merely 0.25%. In 2 cases the skin and subcutaneous tissue injuries were related to the hepatic falciform artery, while in the other two cases the skin and subcutaneous tissue injuries were caused by intercostals arterial chemoembolization or by right hepatic arterial chemoembolization via superior mesenteric artery. For the treatment of the skin and subcutaneous tissue lesions, local symptomatic management was usually enough in mild cases, while local cleaning of the skin damage was probably needed in severe cases. Conclusion: Skin and subcutaneous tissue complications may develop after TACE in patients with malignant liver tumors. Appropriate preventive measures should be taken before performing TACE.

  12. Technique, Complication, and Long-Term Outcome for Endovascular Treatment of Iliac Artery Occlusion

    International Nuclear Information System (INIS)

    The aim of this study was to report technical details, procedure-related complications, and results of endovascular treatment in chronic iliac artery occlusion. Between 2001 and 2008, endovascular treatments of 127 chronic iliac artery occlusions in 118 patients (8 women and 110 men; mean age, 59 years) were retrospectively reviewed. The study was based on Ad Hoc Committee on Reporting Standards (Society for Vascular Surgery/International Society for Cardiovascular Surgery Standards). All occlusions were treated with stent placement with or without preliminary balloon angioplasty. Kaplan-Meier estimators were used to determine patency rates. Univariate and multivariate analyses were performed to determine variables affecting successful recanalization, major complications, early stent thrombosis (≤30 days), and primary and secondary patency rates. Initial technical success was achieved in 117 (92%) procedures. Successful recanalization was obtained by antegrade approach in 69 of 77 (90%) procedures and by retrograde approach in 52 of 105 (50%) procedures (p < 0.001). Complications were encountered in 28 (24%) patients [minor in 7 patients (6%) and major in 22 patients (19%)]. One death occurred in the operative period secondary to iliac artery rupture. Early stent thrombosis was seen in eight (7%) patients. Presence of critical limb ischemia (p = 0.03), subintimal recanalization (p = 0.03), and major complication (p = 0.02) were the independent predictors of early stent thrombosis on multivariate analysis. Primary and secondary patency rates at 5 years were 63 and 93%, respectively. Presence of critical limb ischemia, TASC type C iliac lesions, combined occlusions of both common and external iliac arteries, and major complications were associated with decreased patency rates on univariate analysis, whereas these factors were not independent predictors of stent patency on multivariate analysis. In conclusion, endovascular treatment of iliac artery occlusion has a

  13. Reasons of bleeding complications and prevention methods in endovascular stenting for intracranial artery stenosis

    International Nuclear Information System (INIS)

    Objective: To summarize the reasons of bleeding complications and the prevention methods in stenting for intracranial arterial stenosis. Methods: The clinical data of 366 patients underwent stent-assistant angioplasty of intracranial artery stenosis from July 2006 to December 2011 were analyzed retrospectively. Among them, 14 patients with bleeding complications were found. The initial 100 patients were categorized as early stage group and the rest as mature stage group. The reasons of bleeding and the methods for preventing this complication were summarized. Results: The overall incidence of bleeding complication was 3.8% (14/366). In the early stage group and mature stage group,the rates was 10%(10/100) and 1.5% (4/266). Six cases were related to the operational manipulation and 8 cases secondary to hyperperfusion injury. Death was found in 6 patients,severe disability in 3, mild paralysis in 2, and no neurological deficits in 3. Conclusions: The bleeding complications in stent-assisted angioplasty of intracranial artery stenosis have a high disability and mortality. The improvement of operative techniques and the more strict indications decrease the bleeding complications rate effectively. (authors)

    To evaluate the significance of transcatheter arterial embolization(TAE) of pseudoaneurysm complicating pancreatitis. This study was based on a retrospective analysis of eight cases, in which TAE for control of pseudoaneurysm complicating pancreatitis was attempted. All patients were males, and were aged between 35 and 65(mean, 47) years. Seven had a history of episodes of chronic pancreatitis and one case was the result of acute pancreatitis. All patients underwent diagnostic angiography and superselective embolization. Arteries in which pseudoaneurysm had occurred were the gastroduodenal (n=3D5), inferior pancreaticoduodenal (n=3D1), superior mesenteric artery root (n=3D1), and the celiac axis (n=3D1). Six cases were treated successfully without complications, but in two, embolization failed due to a wide aneurysmal neck arising from the superior mesenteric artery root and celiac axis. In four successful cases, pseudoaneurysms were completely resolved within three to six months of embolization. One of the other two remained as a pseudocyst, while in the other, also a pseudocyst, surgery was performed. Because TAE in patients with pseudoaneurysm complicating pancreatitis has a high success rate, and also leads to absolute resorption of a pseudocyst, TAE is the preferred pre-surgical treatment mode.=20.

    PurposeCarotid endarterectomy and stenting are used to treat carotid stenosis, with the volume of carotid artery procedures increasing over the past decade. We investigated the 10-year trend of periprocedural complications with an increasing procedure volume of carotid stenting at a single tertiary hospital.MethodsWe collected 416 consecutive cases (384 patients) of carotid artery stenting performed for either symptomatic (231 cases, 55.5 %) or asymptomatic (185 cases, 44.5 %) internal carotid artery stenosis at a single center. Periprocedural complication was defined as any stroke, myocardial infarction, or death. Procedure-related outcome included any dissection, hemodynamic event, or periprocedural complication.ResultsThe mean age was 68.8 years (82.8 % males; range of 20–89 years); 23.9 % were older than 75 years. Before the procedure, 99.3 and 56.0 % of patients received antiplatelet and lipid-lowering medication, respectively. The overall periprocedural complication rate was 3.6 % (1.6 and 5.2 % in the asymptomatic and symptomatic group, respectively). The composite outcome of any stroke or death was 3.4 %. Periprocedural complication and procedure-related outcome showed a decremental trend with increasing procedure volume, and this trend remained after adjusting for confounders.ConclusionsOur study suggests that carotid stenting at an experienced center might reduce the periprocedural complications. Our periprocedural complication rate of carotid artery stenting may be comparable to, or somewhat lower than, that reported in other clinical trials.

    International Nuclear Information System (INIS)

    Objective: To evaluate the therapeutic effect of interventional treatment via radial artery access for diabetic foot and to summarize its complications and nursing care. Methods: The interventional treatment via radial artery access was performed in twenty patients with diabetic foot. The preoperative psychological nursing care, the nursing of the punctured site of radial artery and the indwelling catheter, the complications of the puncture site and thrombolytic therapy were reviewed and retrospectively analyzed. Results: Some complications occurred in eight cases, including hematoma at puncture site (n= 1), oozing of blood (n=3), gingival bleeding (n=1) and pain (n=3). No retention of urine or infection occurred. Conclusion: It is very important to pay enough attention to the nursing care of puncture site and indwelling catheter sheath and to make a close observation of patient's condition in order to reduce the occurrence of complications. Rich clinical experience and careful observation after the operation can definitely reduce the occurrence of thrombolytic complications and improve the patient's living quality. (authors)

    Background The main therapeutic treatments for hepatic artery complications after orthotopic liver transplantation (OLT) include thrombolysis, percutaneous transluminal angioplasty, stent placement, and liver retransplantation. The prognosis of hepatic artery complications after OLT is not only related to the type, extent, and timing but also closely associated with the selection and timing of the therapeutic methods. However, there is no consensus of opinion regarding the treatment of these complications. The aim of this study was to determine optimal treatment for hepatic artery complications after OLT.Methods The clinical data of 25 patients diagnosed with hepatic artery thrombosis (HAT) and hepatic artery stenosis (HAS) between October 2003 and March 2007 were retrospectively reviewed. Treatments included liver retransplantation and interventions which contain thrombolysis, percutaneous transluminal angioplasty and stent placement. Results Among five patients with HAT, 3 were treated with thrombolysis. One recovered, one died after thrombolysis and another one died of multi-organ failure after retransplantation because of recurrent HAT. The remaining 2 patients underwent successful retransplantation and have survived after that. Among 12 patients presented with HAS within 1 month postoperatively, 2 patients underwent retransplantation due to irreversible liver failure and another 10 patients were treated with interventions. The liver function failed to improve in 3 patients and retransplantations were performed in 4 patients after stent placement because of ischemic cholangitis. Among 6 patients undergoing liver retransplantations, two died of intracranial hemorrhage and infection respectively. Eight patients presented with HAS after 1 month postoperatively, 5 patients were treated with interventional management and recovered after stent placement. Among another 3 patients presented with HAS, 2 patients' liver function was stable and one patient received late

    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.

    Biloma is an encapsulated bile collection outside the biliary tree due to a bile leak. It is occasionally found following traumatic liver injury or iatrogenic injury to the biliary tract, induced either during an endoscopic or surgical procedure. It is a rare complication of transcatheter arterial embolization (TAE). Although biloma can be shrunk by appropriate aspiration or drainage in majority of cases,we report a case of intrahepatic biloma following repeated TAE for hepatocellular carcinoma (HCC) and complicated by infection and intrahepatic stones. This particular constellation of problems has not been reported before and the intrahepatic stones need to be removed by percutaneous procedure.

    Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula. TAE is a minimally invasive procedure with a low rate of complications, which preserves future fertility. Knowledge of causes of PPH, potential risks, and limitations of TAE is essential for a timely decision, optimizing TAE, preventing irreversible complications, avoiding hysterectomy, and ultimately preserving fertility.

    International Nuclear Information System (INIS)

    Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery.

    We investigated the prognostic role of high MICs for antistaphylococcal agents in patients with methicillin-sensitive Staphylococcus aureus catheter-related bloodstream infection (MSSA CRBSI). We prospectively reviewed 83 episodes from 5 centers in Spain during April 2011–June 2014 that had optimized clinical management and analyzed the relationship between E-test MICs for vancomycin, daptomycin, oxacillin, and linezolid and development of complicated bacteremia by using multivariate analysis. Complicated MSSA CRBSI occurred in 26 (31.3%) patients; MICs for vancomycin and daptomycin were higher in these patients (optimal cutoff values for predictive accuracy = 1.5 μg/mL and 0.5 μg/mL). High MICs for vancomycin (hazard ratio 2.4, 95% CI 1.2–5.5) and daptomycin (hazard ratio 2.4, 95% CI 1.1–5.9) were independent risk factors for development of complicated MSSA CRBSI. Our data suggest that patients with MSSA CRBSI caused by strains that have high MICs for vancomycin or daptomycin are at increased risk for complications. PMID:27192097

    2005-01-01

    Full Text Available CONTEXT: Pancreatic pseudoaneurysm rupture is a rare complication of chronic pancreatitis, with severe prognosis and high mortality. Angiography is usually required for confirmation of the diagnosis, but transabdominal ultrasound and CT angiography are useful noninvasive diagnostic methods. CASE REPORT: We present the case of a 66-year-old patient with a large pancreatic pseudoaneurysm of the superior mesenteric artery complicated with obstructive jaundice. Transabdominal ultrasound with color and power Doppler showed a large pancreatic head pseudoaneurysm that communicated directly to the superior mesenteric artery. Presence of a spinning blood flow inside the pseudoaneurysm was visualized by color Doppler, with evidence of bidirectional flow in the pseudoaneurysm neck that was showed by Doppler spectral analysis. The contrast-enhanced helical computer tomography with multiplanar sagittal and the 3D reconstruction of coronal images confirmed the communication of the pseudoaneurysm with the superior mesenteric artery. The patient was scheduled for selective angiography and embolization. However, clinical evolution was rapidly deteriorating, with collapse, hemorrhagic shock and massive hemorrhage. The patient was operated on and subsequently died despite three days of intensive care, due to disseminated intravascular coagulation and multiorgan failure. CONCLUSION: Non invasive imaging methods consisting of transabdominal ultrasound with color Doppler and contrast-enhanced computer tomography with sagittal reconstruction of coronal images were very useful in the establishment of the diagnosis of pancreatic pseudoaneurysm of the superior mesenteric artery complicated with cholestatic jaundice. However, these imaging methods do not obviate the need for diagnostic and therapeutic angiography, eventually followed by surgical intervention in cases of recurrent bleeding or hemodynamic unstable patients.

  7. Treatment and prevention of serious complications after arterial perfusion chemotherapy of esophageal cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the cause of severe complications after arterial perfusion for esophageal cancer and the methods of prevention. Methods: 368 cases of esophageal cancer were treated with arterial perfusion of drugs for chemotherapy. The treatment numbers were 909 including 215 males and 153 females with the age ranging from 39 to 86. These patients were verified as esophageal cancers histopathologically. Selective angiography of the relevant esophageal segments and drugs for perfusion chemotherapy were undertaken. Results: The complications included one case of paralysis due to spinal cord injury, two cases with esophageal perforation and three cases of necrotic esophagitis. The case of paralysis died of original disease one month after the treatment. Of the cases of esophageal perforation, one formed the esophagus-trachea fistula and survived for eight months after being esophageal stent implantation and the other formed esophagus-mediastinum fistula and died of massive hemorrhage after six weeks. Three cases of necrotic esophagitis occurred at the normal segments of the esophagus and formed esophgeal perforation. Of these three cases, one formed esophago-bronchial fistula and survived up to now after creating drainage stoma of stomach. Two cases of the esophagus-mediastinum and esophagus-bronchus fistula died of severe infection. Conclusions: Severe complications of esophageal arterial catheterization with drugs for chemotherapy are rare. Less harmful, non-ionization contrast medium, low cellular toxicity drugs for chemotherapy with proper doses and concentrations should be selected together with optimal speed of infusion. Esophageal internal stent placement drainage stoma creation of stomach should be the useful adjunct for severe complications. (authors)

    Full Text Available Endovascular therapy for iliac artery chronic total occlusions is nowadays associated with low rates of procedure-related complications and improved clinical outcomes, and it is predominantly used as first-line therapy prior to aortobifemoral bypass grafting. Herein, we describe the case of a patient presenting with an ischemic left foot digit ulcer and suffering complex aortoiliac lesions, who received common iliac arteries kissing stents, illustrating at final antegrade and retrograde angiograms the early recognition of a blood flow obstructing valve-like calcified intimal flap protruding through the stent struts, which was obstructing antegrade but not retrograde unilateral iliac arterial axis blood flow. The problem was resolved by reconstructing the aortic bifurcation at a more proximal level. Completion angiogram verified normal patency of aorta and iliac vessels. Additionally, a severe left femoral bifurcation stenosis was also corrected by endarterectomy-arterioplasty with a bovine patch. Postintervention ankle brachial pressure indices were significantly improved. At the 6-month and 2-year follow-up, normal peripheral pulses were still reported without intermittent claudication suggesting the durability of the procedure. Through stent-protruding calcified intimal flap, is a very rare, but existing source of antegrade blood flow obstruction after common iliac arteries kissing stents.

    Full Text Available Pleural involvement is an uncommon but well recognized complication of chronic pancreatitis, mainly in the form of pleural effusion affecting the left hemithorax. Pancreatic pseudocyst extending to the posterior mediastinum with or without communication with the pleural space is another rare form of this involvement.The treatment of chronic pancreatic pleural effusions and pancreatic pseudocysts generally starts with a conservative approach including bowel rest, drainage of the pleural effusion by repeated thoracentesis or a chest tube, and total parenteral nutrition (TPN for a period of time determined by the clinical course. Other treatment modalities including percutaneous drainage, endoscopic retrograde cholangiopancreatogram (ERCP with stenting of the pancreatic duct and surgical drainage are used if conservative approaches fail.We report a patient with a complicated pancreatic pseudocyst who showed an involvement of the posterior mediastinum and right pleural space, with conspectus sparing of the left hemithorax. The patient had a prolonged and complicated course that included recurrence of the pseudocyst with oral feedings and the development of a splenic artery aneurysm. Some of the above findings have been reported separately as uncommon complications of chronic pancreatitis and pancreatic pseudcyst, but to our knowledge a single case with all these complications was not published in the English literature.

  11. Causes and prevention of serious complication after transcatheter arterial chemoembolization for primary hepatic carcinoma

    International Nuclear Information System (INIS)

    Objective: To analyze the etiological factors and prevention of serious complications after transcatheter arterial chemoembolization (TACE) for primary hepatic carcinoma(PHC). Methods: A consecutive group of 573 patients with PHC received a total of 1252 TACE procedures form January 2005 to July 2007. All patients with complication were treated intensively together with imaging and biochemical examinations, in order to study the causes and preventive measures of the serious complications. Results: After all, the record revealed 3 cases of upper gastrointestival hemorrhage, 6 cases of acute hepatic failure with one death, 1 case of pulmonary embolism, 4 cases of cholecystitis; 2 cases of intrahepatic biloma and one died for gastric perforation. Conclusions: Severe complication with TACE for PHC might be caused by existed poor liver function, portal hypertension, high dose of the chemotherapeutic agent, drug reflux or ectopic embolism etc. So to comply with evidence-based medicine priciples, select the appropriate period for TACE, and use of standardized measures of intervention therapy are essential for preventing and reducing the occurrence of the serious complications.

  12. Radiocephalic Fistula Complicated by Distal Ischemia: Treatment by Ulnar Artery Dilatation

    International Nuclear Information System (INIS)

    Hand ischemic steal syndrome due to a forearm arteriovenous fistula is a rare occurrence. However, its frequency is increasing with the rise in numbers of elderly and diabetic patients. This complication, which is more common for proximal than for distal accesses, can be very severe and may cause loss of hand function, damage to fingers, and even amputation of fingers or the hand. Its treatment is difficult and often leads to access loss. We report here a case of severe hand ischemia related to a radiocephalic fistula successfully treated by ulnar artery dilatation.

  14. Percutaneous implantation of intra-arterial port system for regional drug infusion: results and complications in 110 cases

    International Nuclear Information System (INIS)

    To investigate the feasibility and complications of a percutaneously implantable port system for regional drug infusion. For intra-arterial drug infusion, a 5.8 or 5-F pediatric venous port system was implanted in 110 patients with hepatocellular carcinoma (n=79), liver metastasis (n=16), gallbladder cancer (n=4), stomach cancer (n=3), pancreatic cancer (n=3), Burger's diseases mellitus (n=2), or lymphoma (n=1). All intra-arterial port implantations were performed percutaneously in an angiographic ward through the common femoral artery (n=98), left subclavian artery (n=10), or left superficial femoral artery (n=2). Complications were evaluated during the follow-up period, which ranged from 21 to 530 (mean, 163) days. The technical success rate for percutaneous implantation of the system was 97.3% (107 of 110 patients). The tips of the port catheter were located in the common hepatic artery (n=34), proper hepatic artery (n=49), right hepatic artery quick resulthepatic artery (n=1), descending aorta at T9 level (n=10), left popliteal artery (n=2), right external iliac artery (n=1), left external iliac artery (n=1), or left deep femoral artery (n=1). Complications were encountered in 24 patients (22.4%), namely chamber site infection (n=7), catheter dislodgement (n=7), catheter occlusion (n=3), migration of coil (n=2), disconnection between chamber and catheter (n=1), kinking of catheter (n=1), arterial occlusion (n=1), necrosis of overlying skin (n=1), and leakage around port chamber (n=1). Outcomes of complications included removal of port systems or cessation of therapy in 12 cases (11.2%), correction of catheter location using a guide wire in five (4.7%), thrombolysis with urokinase in three (2.8%), and straightening using a snare in one (0.9%). In three patients, the port system was used without reintervention. Percutaneous implantation of an intra-arterial port system showed a high technical success rate and a low rate of serious complications. The method may be

  15. Analysis of adverse reactions and complications of transcatheter uterine artery embolization (TUAE) for uterine fibroids

    International Nuclear Information System (INIS)

    Objective: To investigate the adverse reactions and complications as well as their preventive and therapeutic measures of TUAE for uterine fibroids. Methods: One hundred and eighty-two patients with uterine fibroids were treated by TUAE. Bilateral uterine arteries were embolized using lipiodol-pingyangmycin emulsion (LPE), together with Gelfoam particles. All patients were hospitalized for 3 to 10 days after TUAE and were followed up for 1 to 24 months to observe the adverse reactions and complications. Results: Adverse reactions of TUAE included postembolization syndrome ( n 182); urinary irritation ( n = 24), and hyporrhea of vagina ( n = 25 ) . Complications of TUAE included expelling of necrotic fibroids per vagina ( n = 5 ); urinary retention ( n = 10); urinary tract infection ( n = 1 ); ulcer of labia minora ( n = 1 ); ecchymosis and ulceration on buttock ( n = 1), and secondary infection of chocolate cyst of ovary. ( n = 1 ). All the above-mentioned side effects of TUAE recovered to normal after expectant or especial treatment without any sequels left. Conclusion: The adverse reactions of TUAE are reversible and the complications of TUAE are preventable and curable

  16. Complications Encountered with a Transfemorally Placed Port-Catheter System for Hepatic Artery Chemotherapy Infusion

    International Nuclear Information System (INIS)

    A port-catheter system was implanted via femoral artery access for hepatic artery chemotherapy infusion. Implantation was attempted in 90 patients and was successful in 88. Blood flow redistribution was performed using embolization coils. In the first ten patients a soft heparin-coated infusion catheter was used. For the following 78 patients we used a stiffer catheter coated with fluorine-acryl-styrene-urethane-silicone (FASUS) copolymer. The catheter was connected to a port implanted subcutaneously below the level of the inguinal ligament. Complications during the procedure and after placement were observed in 7 of 90 patients and 24 of 88 patients, respectively. These included catheter obstruction (11%), dislocation of the catheter tip (10%), drug toxicity (5.7%), and catheter infection (3.4%). In 6 of 10 patients with catheter obstruction, recanalization of the port system was achieved. In 7 of 9 patients with dislocation of the indwelling catheter tip, replacement of the port system was successful. Our complications appear to be comparable with those encountered with the subclavian/brachial approach when the new catheter coating is used. Notable is the avoidance of cerebral infarcts

    2015-08-01

    We report the case of a 50-year-old paraplegic man with a complicated grade III/IV ischiatic pressure sore treated with a propeller flap based on the first perforator of the profunda femoris artery. Our aim was to surgically reconstruct an ischiatic pressure sore in a patient with ankylosis using a fasciocutaneous perforator propeller flap obtained from the posterior region of the thigh. Our decision to perform a profunda femoris artery perforator propeller flap reconstruction was mainly due to the anatomical contiguity of the flap with the site of the lesion and the good quality of the skin harvested from the posterior region of the thigh. The use of the perforator fasciocutaneous flap represents a muscle-sparing technique, providing a better long-term result in surgical reconstruction. The choice of the 180-degree propeller flap was due to its ability to provide a good repair of the pressure ulcer and to pass over the ischiatic prominence in the patient in the forced decubitus position. The operatory course did not present any kind of complication. Using this reconstructive treatment, we have obtained complete coverage of the ischiatic pressure sore. PMID:26495200

  18. The prognosis and prognostic risk factors of patients with hepatic artery complications after liver transplantation treated with the interventional techniques

    International Nuclear Information System (INIS)

    Objective: To investigate the prognosis and prognostic risk factors of hepatic artery complications after orthotopic liver transplantation (OLT) treated with the interventional techniques. Methods: The clinical data of 21 patients with hepatic artery complication after liver transplantation receiving thrombolysis, PTA, and stent placement in our institute from November 2003 to April 2007 were retrospectively analyzed. Based on the prognosis of grafts, 21 patients were divided into poor-prognosis group and non-poor-prognosis group. Fifteen variables (including biliary complication, hepatic artery restenosis, early or late artery complication, and so on) were analyzed in both groups with binary logistic regression analysis to screen out the risk factors related to prognosis of pereutaneous interventional treatment for hepatic artery complications after OLT. Results: Twenty-one patients were followed for mean 436 days, median 464 days (3-1037 days). The poor-prognosis group included 11 patients (5 cases received retransplantation, and 6 died). The mean survival time of grafts in poor-prognosis group was 191 days, and median survival time was 73 days (3-616 days). The mean survival time of grafts in non-poor-prognosis group which included 10 patients was 706 days, and median survival time was 692 days (245-1037 days). Univariate analysis showed there were significant difference in biliary complication, total bilimbin and indirect bilirubin between the two groups. The binary, logistic regression analysis showed the risk factor related to prognosis was with biliary complication before the interventional management (P=0.027, OR=22.818). Conclusion: Biliary complication before interventional management is the risk factor related to poor prognosis of patients with hepatic artery stenosis or thrombosis receiving interventional treatment.

    Introduction: Intra-arterial (IA) thrombolytic intervention for acute thrombosis has been challenged due to the risk of bleeding during the endovascular treatment of ruptured aneurysms. We present the results of IA tirofiban infusion for thromboembolic complications during coil embolization in patients with ruptured intracranial aneurysms. Methods: Thromboembolic events requiring thrombolytic intervention occurred in 39 (10.5%) cases during coil embolization of 372 consecutive ruptured intracranial aneurysms. Maximal aneurysm diameters of 39 patients (mean age, 54.7 ± 13.2 years; 23 female, 16 male) ranged from 2.1 to 13.1 mm (mean, 6.6 ± 3.0 mm). The anterior communicating artery was the most common site (n = 13), followed by the middle cerebral artery (n = 9) and the posterior communicating artery (n = 7). In this series, we used intracranial stents in 10 patients during the procedure. Superselective IA tirofiban infusion through a microcatheter was performed to resolve thrombi and emboli. We assessed the efficacy and safety of IA tirofiban infusion in patients with ruptured aneurysms. Results: Intraarterially administered tirofiban doses ranged from 0.25 to 1.25 mg (mean, 0.71 ± 0.26 mg). Effective thrombolysis or recanalization was achieved in 34 patients (87.2%), and three patients (7.7%) suffered distal migration of clots with partial recanalization. The rest (5.1%) had no recanalization. Nonconsequent intracerebral hemorrhage occurred in two patients (5.1%) after the procedure. Thromboemboli-related cerebral infarction developed in eight patients, and only two patients remained infarction related disabilities. Conclusion: IA tirofiban infusion seems to be efficacious and safe for thrombolysis during coil embolization in patients with ruptured intracranial aneurysms.

    Due to an increase in the number of performed endovascular procedures, the number of local access site complications is rising too. Used mainly for treatment of peripheral arterial disease and coronary heart disease, endovascular procedures are gaining importance. Access site complications include bleeding, haematoma, pseudoaneurysm, arteriovenous fistula and arterial thrombosis. Aiming to reduce immobilisation, length of hospital stay, costs and access site complications, vascular closure devices (VCD) were introduced in the mid 1990s, but current trials failed to demonstrate the superiority of these devices compared to conventional manual compression if it comes to access site complications. We retrospectively evaluated all patients who were treated surgically due to access site complications between 2001 and 2012 in our institution. In total, 522 patients needed vascular surgery to treat different access site complications. During this period, 90,538 percutaneous interventions were performed in our institution, leading to a total incidence of 0.58 % of access site complications. Depending on the frequency of application of VCDs, patients have been grouped in groups A-C. With the more frequent use of VCDs, the incidence of access site complications increased and, in particular, ischaemic complications were seen more often. In conclusion, the application of VCDs to prevent access site complications is questionable and not justified when looking at published data. PMID:25333519

    Contrary to prior case reports that described occasional clinical failures with cefazolin for methicillin-susceptible Staphylococcus aureus (MSSA) infections, recent studies have demonstrated no difference in outcomes between cefazolin and antistaphylococcal penicillins for the treatment of MSSA bacteremia. While promising, these studies described low frequencies of high-inoculum infections, such as endocarditis. This retrospective study compares clinical outcomes of cefazolin versus oxacillin for complicated MSSA bacteremia at two tertiary care hospitals between January 2008 and June 2012. Fifty-nine patients treated with cefazolin and 34 patients treated with oxacillin were included. Osteoarticular (41%) and endovascular (20%) sources were the predominant sites of infection. The rates of clinical cure at the end of therapy were similar between cefazolin and oxacillin (95% versus 88%; P=0.25), but overall failure at 90 days was higher in the oxacillin arm (47% versus 24%; P=0.04). Failures were more likely to have received surgical interventions (63% versus 40%; P=0.05) and to have an osteoarticular source (57% versus 33%; P=0.04). Failures also had a longer duration of bacteremia (7 versus 3 days; P=0.0002), which was the only predictor of failure. Antibiotic selection was not predictive of failure. Rates of adverse drug events were higher in the oxacillin arm (30% versus 3%; P=0.0006), and oxacillin was more frequently discontinued due to adverse drug events (21% versus 3%; P=0.01). Cefazolin appears similar to oxacillin for the treatment of complicated MSSA bacteremia but with significantly improved safety. The higher rates of failure with oxacillin may have been confounded by other patient factors and warrant further investigation. PMID:24936596

    Von Hippel-Lindau syndrome is a rare, genetically based, autosomal dominant disorder. Its course is accompanied by the development of multiple neoplasms with the following tumours diagnosed most commonly in the central nervous system haemangioblastoma, clear cell renal cell carcinoma, phaeochromocytomas, pancreatic islet tumours, and endolymphatic sac tumours. Additionally, renal and pancreatic cystadenomas and epididymal cystadenomas have been diagnosed in males and cystadenomas of the broad ligament of the uterus have been diagnosed in females.The following paper presents the diagnostic way in a boy with vision disorders as the first symptom. Hypertension retinopathy and extremely elevated blood pressure were observed during ophthalmologic consultation. Complications of arterial hypertension were confirmed by echocardiography, which diagnosed hypertension cardiomyopathy. Hypertension retinopathy was confirmed by optical coherence tomography. Examinations performed in the neurology, cardiology, and finally endocrinology indicated a bilateral phaeochromocytoma as the cause of arterial hypertension. Moreover, some genetic investigations showed a mutation in the VHL ex.1 p.Y112 C gene responsible for the hereditary form of phaeochromocytoma which confirmed von Hippel-Lindau syndrome. After surgical treatment of phaeochromocytoma the patient needed careful management according to the surveillance protocol for von Hippel-Lindau disease. PMID:26268347

    Twin reversed arterial perfusion sequence (TRAP) is a rare complication in multifetal monochorionic pregnancies in which a normal ''pump'' twin provides circulation to an abnormal acardiac co-twin, resulting in high-output cardiac dysfunction in the pump twin. To define fetal MRI findings of TRAP sequence. Fetal MR images were retrospectively reviewed in 35 pregnancies complicated by TRAP sequence. Abnormalities of the pump twin, acardiac twin, umbilical cord, placenta and amniotic fluid were reviewed. Acardiac twins were classified as: acephalus (51%), anceps (40%), amorphus (9%), acormus (0%). Common findings in acardiac twins include subcutaneous edema (77%), absent cardiac structures (86%), absent or abnormal thoracic cavity (100%), abnormal abdominal organs (100%), superior limbs absent (46%) or abnormal (51%), and inferior limbs present but abnormal (83%). There were pump twin findings of cardiac dysfunction in 43% and intracranial ischemic changes in 3%. Umbilical cord anomalies were present in 97%. Acardiac twins present with a predictable pattern of malformation with poorly developed superior structures, more normally formed inferior structures and absent or rudimentary heart. Although usually absent, abnormal heart structures can be seen and do not exclude TRAP sequence. Pump twins are commonly normal with exception of findings of cardiac dysfunction and possible brain ischemia. (orig.)

    Full Text Available Abstract We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary team including heart failure specialists, obstetricians, and cardiovascular surgeons. 4 days after admission, her LMC was imaged by dual-source 64 slice Cardiac computed tomography, coronary dissection was identified extending to the lumen, and the presence of pseudoaneurysm was confirmed. She underwent subsequently a staged procedure, which included placement of an intra-aortic balloon pump, cesarean section, and coronary artery bypass grafting. This case illustrates the utility of coronary artery CT imaging to assess the complexity and stability of coronary artery dissections, thereby helping to determine the need for, and timing of revascularization procedures.

    To evaluate and describe the efficacy and side effects of a percutaneous thrombin injection under ultrasonography guidance for the treatment of iatrogenic pseudo aneurysms Eighteen consecutive iatrogenic pseudo aneurysm cases were treated with a thrombin injection. The thrombin was injected into the pseudo aneurysm cavity using a 22-gauge needle under ultrasonographic guidance. The causes of the pseudo aneurysms are as follows: post coronary angiography (9 cases), percutaneous coronary balloon angioplasty (5 cases), cerebral angiography (1 case), transhepatic chemo embolization (1 case), percutaneous trans femoral arterial stent insertion (1 case) and bone marrow aspiration for a marrow transplant (1 case). Only one case required a secondary thrombin injection due to recurrent flow in the pseudo aneurysm lumen, which was detected at the follow up Doppler ultrasound. Other seventeen cases were successfully treated on the first trial. There were no technical failures or complication related to the procedure. The average amount of thrombin injected was 733 IU. Nine out of 18 treated patients (50%) showed mild reactions to the thrombin including mild fever (4 cases), chilling sensation (3 cases), a chilling sensation with mild dyspnea (1 case), mild chest discomfort (1 case) after the thrombin injection. All these side effects were transient and improved several hours later. All the iatrogenic pseudo aneurysms were treated successfully with an ultrasound-guided percutaneous thrombin injection. There was a high rate of hypersensitivity to the bovine thrombin, which precaution should be taken to prevent more serious side effects

    A 70-year-old man was diagnosed with a massive bleeding duodenal ulcer which was refractory to emergency endoscopic management. Angiogram of the coeliac and superior mesenteric arteries revealed bleeding from the superior and inferior pancreaticoduodenal arteries. Transcatheter arterial embolisation of superior and inferior pancreaticoduodenal arteries along with the gastroduodenal artery was performed. Two weeks later he developed severe necrotising pancreatitis of the pancreatic head probably due to ischaemia, which was managed conservatively. Three months later the patient experienced another episode of pancreatitis which progressed into multiorgan dysfunction and the patient passed away. PMID:24879731

  12. The relationship between occupational exposure to lead and manifestation of cardiovascular complications in persons with arterial hypertension

    International Nuclear Information System (INIS)

    The chronic exposure to lead represents a risk factor of arterial hypertension development. Ambulatory blood pressure monitoring is the most prognostically reliable method of measuring of arterial blood pressure. The study is aimed at evaluating the relationship between occupational exposure to lead and manifestation of cardiovascular complications in patients with arterial hypertension. The studies included 73 men (mean age, 54.26 ± 8.17 years) with arterial hypertension, treated with hypotensive drugs: group I-persons occupationally exposed to lead (n = 35) and group II-individuals not exposed to lead (n = 38). An analysis of results obtained during ambulatory blood pressure monitoring disclosed significantly higher values of mean systolic blood pressure, mean blood pressure, pulse pressure, and variability of systolic blood pressure in the group of hypertensive patients occupationally exposed to lead as compared to patients with arterial hypertension but not exposed to lead. The logistic regression showed that a more advanced age, higher concentration of blood zinc protoporphyrin, and a higher mean value of pulse pressure represented independent risk factors of left ventricular hypertrophy in the group of persons with arterial hypertension and chronically exposed to lead (ORage = 1.11; ORZnPP = 1.32; ORPP = 1,43; p < 0.05). In view of the above data demonstration that occupational exposure to lead represents an independent risk factor of increased pulse pressure may be of key importance in the process of shaping general social awareness as to harmful effects of lead compounds on human health.

  13. Pulmonary arterial hypertension: the most devastating vascular complication of systemic sclerosis.

    2009-06-01

    Pulmonary arterial hypertension (PAH) is a devastating vascular complication of a number of CTDs. In patients with SSc, PAH has a dramatic impact on prognosis and survival and is the single most common cause of disease-related death.Yearly echocardiographic screening for PAH is recommended in patients with SSc. If suspected, confirmation of PAH diagnosis by right heart catheterization is necessary. Treatment goals for patients with PAH associated with SSc (PAH-SSc) aim to slow disease progression and improve quality of life. Some measures used to gauge the effect of treatment in patients with PAH-SSc remain to be fully validated; the 6-min walk distance, for example, is a simple and reproducible means of assessing exercise capacity, but there exists a need to understand what constitutes a clinically relevant change in this specific patient population. Currently, pharmacological intervention in PAH-SSc may target one or more of three pathophysiological pathways in PAH. The prostacyclin analogue epoprostenol has been shown to improve exercise capacity and haemodynamics in PAH-SSc patients and similar data are available from smaller studies on trepostinil and iloprost. The dual endothelin receptor antagonist bosentan has been shown to improve exercise capacity and haemodynamics in PAH-SSc, and similar data have been obtained in small numbers of patients treated with the endothelin receptor A antagonists sitaxsentan and ambrisentan. Impaired production of nitric oxide may be addressed by inhibiting phosphodiesterase type-5 with sildenafil or possibly tadalafil. Combinations of multiple targeted therapies may be beneficial to this patient population. PMID:19487219

  15. Complications and Reinterventions in Uterine Artery Embolization for Symptomatic Uterine Fibroids: A Literature Review and Meta Analysis

    International Nuclear Information System (INIS)

    To perform a literature review of the spectrum of complications associated with UAE relative to surgery and compare the risk of reintervention as well as minor, major, and overall complications. Literature review was conducted in PubMed, MEDLINE, Cochrane, and CINAHL databases, and meta-analysis was performed. In randomized clinical trials, common complications were discharge and fever (4.00 %), bilateral uterine artery embolization (UAE) failure (4.00 %), and postembolization syndrome (2.86 %). Two trials showed a significantly decreased risk in major complications with UAE, with odds ratios (ORs) of 0.07143 (0.009426–0.5413) and 0.5196 (0.279–0.9678). None of the trials showed a significant difference in OR for minor complications of UAE. None of the trials showed a significant difference in risk for overall complications of UAE. Three trials showed a significantly increased risk for reintervention with UAE with ORs of 10.45 (2.654–41.14), 2.679 (1.289–5.564), and 9.096 (1.269–65.18). In 76 nonrandomized studies, common complications were amenorrhea (4.26 %), pain (3.59 %), and discharge and fever (3.37 %). In 41 case studies, common complications were discharge and fever (n = 22 cases), repeat UAE (n = 6 cases), and fibroid expulsion (n = 5 cases). Overall, UAE has a significantly lower rate of major complications relative to surgery, but it comes at the cost of increased risk of reintervention in the future. Educating patients about the rate and types of complications of UAE versus surgery, as well as the potential for reintervention, should help the patient and clinician come to a reasoned decision.

    To date, S. alactolyticus endocarditis complicated by middle cerebral artery aneurysm has not been reported. We describe the case of a 65-year-old female with a history of hypertrophic cardiomyopathy with left ventricular outflow tract obstruction presenting with confusion and a apical holosystolic murmur. Angiography of the brain identified new bilobed left middle cerebral artery aneurysm. Serial blood cultures grew S. alactolyticus, and aortic and mitral valve vegetation were discovered on transesophageal echocardiography. The patient was treated with antimicrobial therapy, mitral and aortic valve replacements, and microsurgical clipping of cerebral aneurysm. This case serves to highlight the pathogenicity of a sparsely described bacterium belonging to the heterogenous S. bovis complex. PMID:27525136

    Full Text Available Septic rupture of the common carotid artery following total thyroidectomy may rapidly lead to exsanguination. We present a case report of a 16-year-old girl, diagnosed with a questionable thyroglossal duct cyst. Following the initial operative intervention with local excision of the cyst including resection of the medial part of the hyoid bone, pathology revealed papillary carcinoma. Thus secondary total thyroidectomy with locoregional lymphadenectomy was performed. One week later, a wound infection developed, necessitating lavage and drainage. On the 8th postoperative day, a dramatic bleeding of the right common carotid artery occurred. To our knowledge, this is the first reported case in the literature with a septic bleeding of the common carotid artery following total thyroidectomy after one week.

    Prostatic artery embolization (PAE) is an alternative treatment for benign prostatic hyperplasia. Complications are primarily related to non-target embolization. We report a case of ischemic rectitis in a 76-year-old man with significant lower urinary tract symptoms due to benign prostatic hyperplasia, probably related to nontarget embolization. Magnetic resonance imaging revealed an 85.5-g prostate and urodynamic studies confirmed Inferior vesical obstruction. PAE was performed bilaterally. During the first 3 days of follow-up, a small amount of blood mixed in the stool was observed. Colonoscopy identified rectal ulcers at day 4, which had then disappeared by day 16 post PAE without treatment. PAE is a safe, effective procedure with a low complication rate, but interventionalists should be aware of the risk of rectal nontarget embolization.

    Small bowel herniation underneath the iliac vessel after transperitoneal pelvic lymphadenectomy is a rare complication. This report describes the first case of bowel incarceration behind the external iliac artery after transperitoneal robotic-assisted radical prostatectomy with extended lymph node dissection in a patient with prostate cancer 1 year after surgery. After diagnosis on CT scan, an open resection of the ischemic bowel was performed. Because of thrombosis, the external iliac artery was opened, the clot was removed and the elongated artery was resected with end-to-end anastomosis. In case of a meandering iliac artery, a retroperitonealization after pelvic lymphadenectomy might be discussed. PMID:27313985

    Full Text Available Objective. The objective of this analysis was to compare clinical and cost outcomes associated with patients who had suspected or documented methicillin-resistant Staphylococcus aureus (MRSA infections treated with daptomycin, vancomycin, or linezolid in complicated skin and skin structure infections (cSSSIs. Design. This was a retrospective analysis conducted from February to June of 2007. Appropriate data was collected, collated, and subsequently evaluated with the purpose of quantifying length of stay, antibiotic therapy duration, clinical cure rates, adverse drug events, and cost of hospitalization. Results. All 82 patients included in the analysis experienced clinical cure. The duration of antibiotic therapy was similar among the three groups yet the length of hospitalization was slightly shorter in the daptomycin group. Conclusions. The incidence of resistant staphylococcal infections is increasing; therefore, judicious use of MRSA active agents is paramount. Future studies are necessary to determine if MRSA treatment options can be stratified based on the severity of the infectious process.

    Full Text Available Background. Spontaneous rupture of an ovarian artery aneurysm is a rare but usually life-threatening event. It is most often associated with pregnancy or fibroids. Our case followed a normal vaginal delivery and then a delayed presentation with features similar to other less life-threatening postpartum conditions. The diagnosis could have been missed but for the meticulous and timely interventions which avoided catastrophic outcome. Case. This is a case of a multiparous woman with rupture of a left ovarian artery aneurysm, causing massive retroperitoneal hemorrhage and hematoma that required a combination of arterial embolization, percutaneous CT scan guided drainage, and surgical evacuation of the hematoma. Conclusion. Spontaneous rupture of ovarian artery should be considered as one of the differential diagnoses in the immediate postpartum period especially when the clinical symptoms do not correlate with the amount of blood loss. A high index of suspicion, prompt diagnosis, intervention, and a multidisciplinary approach in the management were the elements of a successful outcome in this case.

    Monochorionic twins are subjected to specific complications which originate in either imbalance or abnormality of the single placenta serving two twins. This unequal placental sharing can cause complications including twin-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence (TAPS), selective intrauterine growth restriction or twin reversed arterial perfusion sequence (TRAP). Monochorionicity also makes the management of these specific complications as well as that of a severe malformation in one twin hazardous since the spontaneous death of one twin exposes the co-twin to a risk of exsanguination into the dead twin and its placenta. The latter is responsible for the death of the co-twin in up to 20% of the cases and in ischemic sequelae in about the same proportions in the survivors. Although the symptoms of all these complications are very different, the keystone of their management comes down to either surgical destruction of the inter-twin anastomoses on the chorionic plate when aiming at dual survival or selective and permanent occlusion of the cord of a severely affected twin aiming at protecting the normal co-twin. This can be best achieved by fetoscopic selective laser coagulation and bipolar forceps cord coagulation respectively. PMID:20855238

    We report the case of a 65-year-old man who developed norepinephrine-resistant vasoplegic syndrome after elective off-pump coronary artery bypass surgery (OPCAB). The failure of norepinephrine to improve the patient's hemodynamics prompted us to start treatment with vasopressin; within 30 minutes, the hemodynamics began to improve. After 12 hours, the patient was stable enough to be weaned from the vasopressin. He was discharged from the hospital on the 10th postoperative day. To our knowledg...

    Authors report a case of a 31 years old patient who eliminate a urinary stone which contains a platinium coil. Five years ago, this patient had a percutaneous nephrolithotomy. A persistent hematuria was successfully managed with angioembolization of a lower polar artery branch. One of the coils was deployed too distally. It was not efficient, it rolled itself up in the pseudoaneurysm cavity. Different physio pathological hypothesis are developed to explain this expulsion. PMID:17634005

  11. Intracranial arterial infusion chemotherapy for lung cancer complicated by brain metastases: a clinical observation

    International Nuclear Information System (INIS)

    Objective: T evaluate the efficacy of intracranial arterial infusion chemotherapy in treating advanced lung cancer with brain metastases and to discuss the factors influencing prognosis. Methods: From September 2007 to August 2008, a total of 27 patients of lung cancer with brain metastases received intracranial arterial infusion chemotherapy. This procedure was performed every 4 weeks for three times in succession. Follow-up brain MRI was regularly performed at intervals of eight weeks after the treatment in order to evaluate the therapeutic efficacy, which was conducted until the disease became worse or the patient could tolerate the drug toxicity no longer. Results: All 27 cases were treated 3 times at least, and one case received 7 times. Of the 27 cases, partial response was obtained in 15 (55.6%), stable condition in 8 (29.6%) and deterioration in 4 (14.8%), although no one showed complete alleviation. The effective rate for intracranial lesions was 55.6% (15/27) and the 85.2% of lesions (23/27) were brought under control. Overall median survival time was 7 months. The 6-month survival rate and 1-year survival rate were 81.5% and 14.8%, respectively. Conclusion: Intracranial arterial infusion chemotherapy is one of the most effective methods for the treatment of lung cancer associated with brain metastases. Karnofsky performance status ≥ 60 and absent of extra cranial metastases are good prognostic factors for lung cancer patients with brain metastases. (authors)

  13. Role of high resolution contrast-enhanced magnetic resonance angiography (HR CeMRA) in management of arterial complications of the renal transplant

    International Nuclear Information System (INIS)

    Introduction: Transplant renal artery (RA) stenosis (TRAS) is the most frequent posttransplantation vascular complication. Contrast enhanced magnetic resonance (CeMRA) angiography has been established as the preferred imaging technique for the evaluation of TRAS because it does not require the use of iodinated contrast material and does not expose the patient to ionizing radiation. Digital subtraction angiography (DSA) is the gold standard in the evaluation of arterial tree of the renal allograft. Aim of the work: This study was carried out to assess the accuracy of CeMRA in the detection of arterial complications after renal transplantation. Patients and methods: Thirty renal transplant patients with suspected arterial complications in which both CeMRA and DSA were performed were included in the study. The HR CeMRA shows 93.7% sensitivity, 80% specificity, 88.2% positive predictive value, 88.9% negative predictive value and 88.5% accuracy. Conclusion: HR CeMRA is an accurate reliable tool in the assessment of arterial complications after renal transplantation. It may replace DSA as a diagnostic modality with reservation of interventional techniques for endovascular treatment of suitable cases.

  14. Peripheral macroembolism complicating laser angioplasty of arteries of extremities - therapy with radiologic interventional methods

    International Nuclear Information System (INIS)

    From 1987 to 1989 in the Barmherzige Brueder Hospital in Linz/Austria 160 arteries of extremities were treated with laser-assisted balloon dilatation. During these interventions peripheral macroembolism occurred 8 times. The mean length of the recanalised segment was 8.7 cm and thus longer than average (6.5 cm). All 8 cases were successfully treated by aspiration or aspiration combined with local lysis. No adverse effects on long-term results were noted. In 4 cases an early occlusion of the recanalised segment was diagnosed within 48 hours after laser-assisted angioplasty, three times accompanied by embolism. These emboli, too, were removed by aspriation and lysis. To reduce the risk of embolisation strict rules of indication concerning the age of an occlusion have to be observed and mechanical trauma has to be minimised. (orig.)

    Full Text Available Introduction: Up to 12% of patients undergoing coronary artery bypass graft have pulmonary complications. Smoking can cause a six-time increase in pulmonary complication after major surgery. The most common pulmonary changes after CABG are decrease in FRC, VC and atelectasis. In this study, the effect of oral N-acetyl-cystein in reduction of severity of hypoxemia and atelectasis in current smokers who smoked more than 10 packs/year and had undergone CABG was evaluated. Methods: In the study, 54 current smoker patients were selected randomly and allocated to two drug and placebo groups. In the study group, 300mg N-acetyl-cystein (ACC long containing vitamin C was prescribed two times a day from 4 days before operation up to 3 days after surgery and in control group, effervescent vitamin C tablet was prescribed as placebo. Patients with body mass index more than 35, NYHA class IV, those who needed intra aortic balloon pump and those who needed reoperation due to bleeding were excluded from the study. In all patients, spirometry was done in the preoperative visit and FEV1/FVC was determined. Induction and maintenance of anesthesia was similar in all patients. Arterial blood gas samples were obtained immediately after anesthesia induction and 4 to 6 hours after extubation. Chest X ray was taken before, 6 to 10 hours after extubation and 3rd postoperative day. Severity of atelectasis was also measured. Quantitative & qualitative data was analyzed by ANOVA and Chi-square tests, respectively. Pvalue<0.05 was considered as statistically significant. Results: Both groups were similar with respect to demographic data including ejection fraction, NYHA class, FEV1/FVC, cigarette smoking and Lima harvesting. The ratio of arterial oxygen pressure to fraction of inspiratory oxygen Pao2/FIo2 was not significantly different after induction but this difference was strongly significant (Pvalue<0.005 after extubation.

    Full Text Available Background:This case report describes about the female patient who came with cough, breathlessness and neck pain after one month following coronary artery bypass grafting to the cardiology department. Chest radiograph was taken and diagnosed it as pleural effusion with atelectasis of left lower lobe. Later therapeutic thoracentesis was done to aspirate the fluid and referred the case to physiotherapy. Thorough physical examination showed reduced neck mobility due to trigger points and spasm of the neck muscles which are causing pain, and also breathlessness on walking, on percussion dull note on left lower lobe, on auscultation crackles are heard with diminished breath sounds over the left lower lobe, altered chest symmetry reduced chest expansion of the lower chest. To reduce neck pain and improve neck mobility she was treated with cryostretches,trigger point release technique, myofascial release and muscle energy techniques. She was treated with positioning, chest percussion, vibration and shaking, deep breathing exercises, thoracic expansion exercises, segmental breathing to lower lobes, incentive spirometry every one hour ten times, trunk and thoracic mobilityexercises were done twice in a day to reduce breathlessness. After 15 days again x-ray was taken where lung was re-expanded and also there are free movements of the neck without pain.

    Full Text Available When coronary artery, which is located subepicardially, submerges into myocardium and then, after a short intramural course, again appears subepicardially, it is called embedded coronary, while a part of myocardium above - a myocardial bridge. Muscular bridges are usually small and have no clinical significance. In the proximal part of coronary artery, preceding a myocardial bridge, there occurs a disturbance of blood course and myocardial perfusion, turbulence, collecting of lipids and mucopolysaccharides, lesion of elastica, which all leads to atheromatous lesions of intima of the arterial proximal part and to the resultant complications of atheroma. Degenerative changes of myocardium and its blood vessels, and in connection with it myocardial vulnerability, could be a consequence of this congenital arterial variation. We report a case of a 40-year-old male, without medical data about previous diseases, who died suddenly and unexpectedly in his apartment. The autopsy and microscopical examination revealed an acute ischemic lesion, myocardial bridge in the middle part of the left coronary artery descending branch and the complicated atherosclerotic plaque proximally of this bridge.

    Full Text Available Background and Aim: In metastatic colorectal cancer, in the last 10 years, hepatic arterial infusion (HAI was proposed as an alternative using various chemotherapy agents. The insertion of a port-a-cath in the hepatic artery is needed and there are various methods to do that, from classical to interventional approach. Patients and Methods: Patients were selected with metastatic colorectal cancer with inoperable liver metastasis only and were treated with oxaliplatin HAI, combined with systemic intravenously chemotherapy. The port-a-cath insertion was done using the classical approach in the same surgical time with the subclavicular vein port insertion. Results: Thirty-two patients were treated. During our experience we did not encounter intra-operative complications. Among the immediate post-operative complications mainly consisted of metabolic complications (6.2% and infection was the most common late complication (9.4%. In one case we removed the port-a-cath, thus the patient was not able to continue the treatment. Conclusion: When talking about the safety of the procedure, we didn’t find it to be more at risk for the patients compared to the literature. Even though the antibiotic prophylaxis is done regularly, the risk of infection remains, especially as a late complication.

  1. Case of Behçet's disease complicated by oculomotor nerve palsy associated with internal carotid artery-posterior communicating artery aneurysm.

    2015-03-01

    Behçet's disease (BD) is a relapsing systemic inflammatory disorder of unknown etiology involving systemic vasculitis. Vasculitis in BD results from the involvement of arteries, veins and blood vessels of all sizes, which leads to the three major manifestations of this condition: venous occlusion, arterial occlusion and aneurysm formation. Therefore, whole-body vascular involvement should always be considered in BD patients. Here, we describe the first appearance of an internal carotid-posterior communicating artery aneurysm, resulting in complete oculomotor nerve palsy in a BD patient. A 44-year-old Japanese man suffered from recurrent episodes of erythema nodosum that had presented on the lower extremities for the past 2 years. His condition was diagnosed as an incomplete type of BD based on relapsing oral and genital ulcers, skin eruptions, such as erythema nodosum and folliculitis, a positive pathergy test and systemic arthralgia. Ten years after his initial clinical presentation, he had manifestations of right-sided ptosis and cyclic dull pain in his right temporal region. Magnetic resonance imaging and angiography revealed a right internal carotid artery-posterior communicating artery aneurysm. Although oculomotor nerve palsy associated with internal carotid artery-posterior communicating artery aneurysm in a BD patient has not been reported previously, our report highlights the fact that this abnormal manifestation should be considered in those with vasculo-BD.

    Background. K-wires are thought to be extremely safe implants and complications as a result of direct insertion or migration are very rare. Complications may be life-threatening in some instances where migration results in injury to vital organs. We report one such case where antegrade migration of K-wire from the hip resulted in injury to external iliac artery and formation of external iliac artery-appendicular fistula. No such complication due to migration has ever been reported in the literature. Case Description. A 15-year-old boy presented with lower abdominal pain, right lower limb swelling and pain, inability to walk, and rectal bleeding for 1 month after 2 K-wires had been inserted in his right hip joint for treatment of slipped capital femoral epiphysis the previous year. On investigation, he was diagnosed to have external iliac artery-appendicular fistula for which he was surgically treated. Clinical Relevance. Antegrade migration of K-wire from hip joint may lead to life-threatening injuries which can be minimized by bending the end of the K-wire, keeping the tip protruding outside the skin wherever possible and by early removal of K-wire once its purpose has been achieved.

    2016-01-01

    BACKGROUND The potential risk of vascular complications associated with heparin, the dose of heparin therapy has not been exactly examined in patients undergoing transradial angiography. Thus, this study was aimed to compare referral arterial thrombosis, hematoma and hemorrhagic complications with 2500 and 5000 IU arterial heparin and the association of these complications with predictors in patients undergoing diagnostic angiography. METHODS This prospective, randomized, double-blind controlled trial was carried out on 441 patients aged ≥ 18-year-old in Isfahan, Iran. They were referred for diagnostic coronary angiography with radial access. First participants were randomized into to inject either 2500 IU (group A) or 5000 IU (group B) of heparin. Study’s primary endpoints were thrombosis, hematoma, and hemorrhage. RESULTS The frequency of thrombosis was 25.5% in group A vs. 2.3% in group B (P < 0.001), while the frequency of hematoma had no significant differences in group A and B. None of patients in both groups had hemorrhage. Using 5000 IU of heparin protected the occurrence of thrombosis by 95% [odds ratio (OR): 0.05, 95% confidence interval (CI): 0.02-012] after adjustment for confounders. CONCLUSION The low dose (2500 IU) versus standard dose (5000 IU) of heparin use increased the risk of thrombosis following trans-radial diagnostic coronary angiography, with no effect on hematoma and bleeding.

    Full Text Available Introduction: Intracranial dissecting aneurysms have been increased due to recent advancements in diagnostic imaging. However there have been little article with subarachnoid hemorrhage and cerebral infarction occurring almost at the same time. We performed the surgical treatment and obtained good result.Case presentation: A 47-year-old male presented to our hospital with chief complaints of sudden headache and mild paralysis of the left lower extremity. Brain imaging at admission revealed cerebral infarction in the right frontal lobe and subarachnoid hemorrhage in the frontal convexy and anterior interhemispheric fissure. The left and right internal carotid angiography showed a bulging cerebral aneurysm at the left A1–A2 junction and stenosis and arterial dissections in the peripheral of the bilateral anterior cerebral artery. Wrapping was performed for the dissecting aneurysm of the left anterior cerebral artery. For the right anterior cerebral artery, trapping was performed at the A2 segment without vascular anastomosis. The patient’s postoperative course was uneventful.Conclusion: A consensus has not been reached on the treatment for intracranial dissecting aneurysms. Proximal trapping without vascular reconstruction was performed for the right anterior cerebral artery without vascular anastomosis to prevent rebleeding. However no symptoms of neurological deficiency were observed. Proximal trapping of dissecting aneurysm seems to be a good option when patient’s functional and life prognosis are taken into account in case that vascular reconstruction will be anticipated difficulty.

    We present a case of a 52-year old female patient with intermittent gastrointestinal bleeding and iron deficiency anaemia. Repeated endoscopic investigation revealed no diagnosis, but contrast-enhanced computed tomography showed a splenic artery pseudo-aneurysm secondary to chronic alcoholic pancreatitis. A distal pancreatectomy and splenectomy was performed. Hemosuccus pancreaticus is an uncommon cause of gastrointestinal bleeding, most frequently associated with chronic pancreatitis. Erosion of a peripancreatic artery by a pseudocyst can cause a pseudoaneurysm and rupture occurs in up to 10% of the cases. Bleeding from a pseudocyst wall or rupture of an atherosclerotic or traumatic aneurysm is rare. Angiography, contrast-enhanced computed tomography and endoscopic findings can be diagnostic in the majority of cases. Angiographic embolization or surgery are both therapeutic options depending on underlying nonvascular pancreas related indications requiring surgery. We discuss diagnostic pitfalls and current therapeutic strategies in the management of this disease. PMID:26712055

    Full Text Available Introduction: Percutaneous subclavian vein catheterization is one of the most common invasive procedures performed in cardiac surgery. The aim of this study was to compare left and right subclavian vein catheter placement via the infraclavicular approach in patients who undergo coronary artery bypass graft (CABG surgery.Methods: This prospective, randomized clinical trial was performed in193 patients. The technique applied for cannulation was infraclavicular approach for both the right and the left sides. Subclavian vein of other side was attempted only when catheterization at initial side was unsuccessful at two attempts. The success and complication rates were compared for the two sides.Results: On193 patients, catheterization attempts were performed. 177 catheterizations (91.7% were successful during the first attempt, 105 (92.1% on the right side and 72 (91.1% on the left side. There was no significant difference between success rate and side of catheterization. Malposition of the catheter tip on the right side (9.6% was significantly more than the left side (0% (P= 0.003. The differences in other complications on two sides were statistically insignificant.Conclusion: Compared with the right side, insertion of the cannula on the left side resulted in fewer catheter tip misplacements. Incidence of cannulation failure and other complications were similar on both sides.

    Full Text Available Abstract Background Heart surgery is associated with an occurrence of pulmonary complications. The aim of this study was to determine whether pre-surgery respiratory physiotherapy reduces the incidence of post-surgery pulmonary complications. Methods Observational study of 263 patients submitted to off-pump coronary artery bypass grafting (CABG surgery at the A Coruña University Hospital (Spain. 159 (60.5% patients received preoperative physiotherapy. The fact that patients received preoperative physiotherapy or not was related to whether they were admitted to the cardiac surgery unit or to an alternative unit due to a lack of beds. A physiotherapist provided a daily session involving incentive spirometry, deep breathing exercises, coughing and early ambulation. A logistic regression analysis was carried out in order to identify variables associated with pulmonary complications. Results Both groups of patients (those that received physiotherapy and those that did not were similar in age, sex, body mass index, creatinine, ejection fraction, number of affected vessels, O2 basal saturation, prevalence of diabetes, dyslipidemia, exposure to tobacco, age at smoking initiation, number of cigarettes/day and number of years as a smoker. The most frequent postoperative complications were hypoventilation (90.7%, pleural effusion (47.5% and atelectasis (24.7%. In the univariate analysis, prophylactic physiotherapy was associated with a lower incidence of atelectasis (17% compared to 36%, p = 0.01. After taking into account age, sex, ejection fraction and whether the patients received physiotherapy or not, we observed that receiving physiotherapy is the variable with an independent effect on predicting atelectasis. Conclusion Preoperative respiratory physiotherapy is related to a lower incidence of atelectasis.

  18. Uterine Artery Embolization in 101 Cases of Uterine Fibroids: Do Size, Location, and Number of Fibroids Affect Therapeutic Success and Complications?

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate whether the size, location, or number of fibroids affects therapeutic efficacy or complications of uterine artery embolization (UAE). Patients with symptomatic uterine fibroids (n = 101) were treated by selective bilateral UAE using 500- to 710-μm polyvinyl alcohol (PVA) particles. Baseline measures of clinical symptoms, sonography, and MRI taken before the procedure were compared to those taken 1, 3, 6, and 12 months later. Complications and outcomes were analyzed for associations with fibroid size, location, and number. Reductions in mean fibroid volume were similar in patients with single (66.6 ± 21.5%) and multiple (67.4 ± 25.0%) fibroids (p-value = 0.83). Menstrual improvement occurred in patients with single (93.3%) and multiple (72.2%) fibroids (p = 0.18). Changes in submucosal and other fibroids were not significantly different between the two groups (p's > 0.56). Linear regression analysis between primary fibroid volume as independent variable and percentage reduction of fibroid volume after 1 year yielded an R2 of 0.083 and the model coefficient was not statistically significant (p = 0.072). Multivariate regression models revealed no statistically or clinically significant coefficients or odds ratios for three independent variables (primary fibroid size, total number, and fibroid location) and all outcome variables (percent reduction of uterus and fibroid volumes in 1 year, improvement of clinical symptoms [menstrual, bulk related, and urinary] in 1 year, and complications after UAE). In conclusion, neither the success rate nor the probability of complications was affected by the primary fibroid size, location, or total number of fibroids

  19. Endoscopic endonasal approach for the treatment of a large clival giant cell tumor complicated by an intraoperative internal carotid artery rupture

    International Nuclear Information System (INIS)

    Giant cell tumors (GCTs) are primary bone neoplasms that rarely involve the skull base. These lesions are usually locally aggressive and require complete removal, including the surrounding apparently healthy bone, to provide the best chance of cure. GCTs, as well as other lesions located in the clivus, can nowadays be treated by a minimally invasive fully endoscopic extended endonasal approach. This approach ensures a more direct route to the craniovertebral junction than other possible approaches (transfacial, extended lateral, and posterolateral approaches). The case reported is a clival GCT operated on by an extended endonasal approach that provides another contribution on how to address one of the most feared complications attributed to this approach: a massive bleed due to an internal carotid artery injury

    Full Text Available Abstract Introduction Distal arterial embolisation and subsequent aneurysm formation are rare occurrences and most are secondary to trauma. We have found no case reports that describe posterior tibial aneurysm formation secondary to bacterial endocarditis. Case presentation We report the case of a 47-year-old Caucasian man who, 2 years after an episode of subacute bacterial endocarditis, presented with signs and symptoms consistent with posterior tibial aneurysm formation. Conclusion Posterior tibial aneurysm formation is a rare occurrence, most commonly occurring after trauma and, although other causes have been described, to our knowledge, endocarditis has not been implicated before, and as such should therefore be borne in mind when dealing with cases where no obvious aetiology is evident.

    Although uncommon, mycotic aneurysms in infants can be lethal because of the high risk of rapid expansion and rupture. Most catheter-associated mycotic aneurysms reported in the first year of life develop following umbilical artery catheterizations. We describe the sonographic detection of an early stage mycotic aneurysm in a 4-month-old following femoral artery catheterization complicated by methicillin-resistant Staphylococcus aureus (MRSA) septicemia. We also describe the sonographic and radiographic progression of this mycotic aneurysm before surgery. (orig.)

    Splenic arteriovenous fistula (SAVF) accounts for an unusual but well-documented treatable cause of portal hypertension[1-4]. A case of a 50-year-old multiparous female who developed suddenly portal hypertension due to SAVF formation is presented. The patient suffered from repeated episodes of haematemesis and melaena during the past twelve days and thus was emergently admitted to hospital for management. Clinical and laboratory investigations established the diagnosis of portal hypertension in the absence of liver parenchymal disease. Endoscopy revealed multiple esophageal bleeding varices. Abdominal computed tomography (CT)and transfemoral celiac arteriography documented the presence of a tortuous and aneurysmatic splenic artery and premature filling of an enlarged splenic vein, findings highly suggestive of an SAVF. The aforementioned vascular abnormality was successfully treated with percutaneous transcatheter embolization. Neither recurrence nor other complications were observed.

    A 15-year-old boy, who had had a furuncle on his femur, developed femoral pyomyositis and osteomyelitis complicated by septic pulmonary embolism. Panton-Valentine leukocidin-positive (PVL(+)) ST59 methicillin-susceptible Staphylococcus aureus (MSSA) was isolated from pus and blood. Chemotherapy was started with cefazolin, followed by combination therapy with meropenem/vancomycin with surgery. The MSSA (strain KS1) was positive for increased levels of cytolytic peptide (psmα and hld) and staphylococcal enterotoxin B (SEB), and manifested IS1216V-mediated multidrug resistance (to erythromycin, clindamycin, kanamycin, streptomycin, and chloramphenicol), similar to a genome-analyzed reference strain (PM1) of ST59/SCCmecV(5C2&5) community-associated methicillin-resistant S. aureus (Taiwan CA-MRSA), but unlike another reference strain (M013) of Taiwan CA-MRSA in terms of resistance. The data suggest that CA-MSSA KS1, characterized by PVL, increased levels of cytolytic peptide, SEB, and multidrug resistance, is a possible ancestral strain of Taiwan CA-MRSA and causes the unique association of osteomyelitis and septic pulmonary embolism, requiring complicated management.

    Lindsay, Jodi A.

    The staphylococci are Gram-positive cocci that divide to form clusters that look like grapes. By 16S ribosomal sequencing, they are most closely related to the Gram-positive, low G+C content Bacillus-Lactobacillus-Staphylococcus genera (Woese, 1987). There are over 30 species of staphylococci identified, and they are typically found on the skin and mucous membranes of mammals. About a dozen species are frequently carried on humans, including Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus capitis, Staphylococcus hominis, Staphylococcus cohnii, Staphylococcus lugdunensis, Staphylococcus schleiferi, Staphylococcus saprophyticus, Staphylococcus simulans, Staphylococcus warneri and Staphylococcus xylosus.

    Full Text Available Introduction. We are presenting a case report of an infected modular abdominal stent graft. Case Presentation. A 67-year-old male patient three years after Cook’s modular abdominal aortic aneurysm (AAA graft implantation for juxtarenal AAA with an implantation of a stent extension into the right common iliac artery for type Ib endoleak. The patient was admitted into our center in severe condition with suspected retroperitoneal bleeding. Computed tomography angiography (CTAG confirmed retroperitoneal bleeding in the right common iliac artery. An urgent surgical revision was indicated; destructed arterial wall around the stent extension in the right common iliac artery was discovered. Due to the severe state of health of the patient, a resection of the infected stent and affected arterial wall was performed, followed by an iliac-femoral crossover bypass. The patient was transported to the intensive care unit with hepatic and renal failure, with maximal catecholamine support. Combined antibiotic treatment was started. The patient died five hours after the procedure. The cause of death was multiorgan failure caused by sepsis. Hemocultures and perioperative microbiological cultures showed the infection agent to be Staphylococcus aureus methicillin sensitive. Conclusion. Stent graft infection is a rare complication. Treatment is associated with high mortality and morbidity.

    This is a case of a 78-year-old male patient with multiple angiomyolipomas of a solitary right kidney. The largest of these tumors (maximum diameter: 13.4 cm) caused significant extrinsic compression of the inferior vena cava complicated by thrombosis of this vessel. Treatment of thrombosis with anticoagulants had been ineffective and the patient had experienced a bleeding episode from the largest right renal angiomyolipoma, which had been treated by transarterial embolization in another institution, 4 months prior to our intervention. Our approach included superselective transarterial embolization of the dominant, right kidney angiomyolipoma with hydrogel microspheres, which was combined, 20 days later, with ultrasonographically guided radiofrequency ablation. Both interventions were uneventful. Computed tomography 2 months after ablation showed a 53% reduction in tumor volume, reduced space-occupying effect on inferior vena cava, and resolution of caval thrombus. Nine months after intervention the patient has had no recurrence of thrombosis or hemorrhage and no tumor regrowth has been observed. The combination of superselective transarterial embolization and radiofrequency ablation seems to be a feasible, safe, and efficient treatment of large renal angiomyolipomas. PMID:27293932

    we report a case of a 74-year-old woman with a 16-year history of a double bilo-enteric anastomosis due to resected hilar cholangiocarcinoma [Type Ⅲb Klatskin tumor]. The patient presented with cholangitis secondary to benign anastomotic stenosis which resulted in a large intrahepatic biloma. In order to restore the patency of the anastomosis and overcome cholangitis, several attempts took place,including endobiliary stenting, balloon-assisted biloplasty and transhepatic billiary drainage. Anastomotic patencywas achieved, complicated, however, by persistent upper gastro-intestinal bleeding, presented as hemobilia. A biloma-induced pseudoaneurysm of the left hepatic artery was diagnosed. This had ruptured into the biliary tract,and presented the actual cause of the hemobilia. Selective embolism of the pseudoaneurysm resulted in control of the hemorrhage, and was successfully combined with transhepatic dilatation of the anastomosis and percutaneous drainage of the biloma. The patient was ultimately cured and seems to be in excellent condition, 5 mo after treatment.

    2015-01-01

    A 76-year-old man was admitted with bleeding per-urostomy following a collapse at home. Three weeks prior to the admission, he had undergone a radical cystoprostatectomy and formation of ileal-conduit for an extensive bladder carcinoma. A CT angiogram revealed a possible small source of bleeding within the ileal-conduit itself, which settled with conservative management. However, prior to discharge he developed profuse fresh bleeding from the urostomy, which could not be controlled. The patient underwent an emergency endoscopy of the conduit and laparotomy, which revealed a fistula between the right external iliac artery and the proximal end of the ileal-conduit. The right iliac artery was ligated and an emergency left-to-right femoral-femoral crossover bypass was performed. The right ureter was stented and rediverted through the ileal-conduit and the left ureter was stented at a later date. He unfortunately had a stormy postoperative recovery with further episodes of per-urostomy bleeding and no identified source. PMID:25819824

    Full Text Available Intracardiac thrombus, pulmonary artery aneurysms, deep vein thrombosis, and pulmonary thromboembolism are rarely seen symptoms of Behcet’s disease. A 20-year-old female patient was admitted for complaints of cough, fever, palpitations, and chest pain. On the dynamic thorax computed tomograms (CT obtained because of significantly enlarged hilar structures seen on chest radiograms, aneurysmal dilatation of the pulmonary artery segments bilaterally, chronic thrombus with collapse, and consolidation substances compatible with pulmonary embolism involving both lower lobes have been observed. It is learned that, four years ago, the patient had been diagnosed with Behcet’s disease and received colchicine treatment but not regularly. The patient was hospitalized. On the transthoracic echocardiogram, a thrombosis with a dimension of 4.2 × 1.6 cm was recognized in the right ventricle. On abdomen CT, aneurysmal iliac veins and deep vein thrombus on Doppler ultrasonograms were diagnosed. At the controls after three months of immunosuppressive and anticoagulant therapies, some clinical and radiological improvements were recognized. The patient suspended the treatment for a month and the thrombus recurred. We present our case in order to show the effectiveness of immunosuppressive and anticoagulant therapies and rarely seen pulmonary thromboembolism in recurrent Behcet’s disease.

  1. Use of the frozen elephant trunk technique in complicated chronic dissection with porcelain aorta and visceral arteries originating from different lumens.

    2016-04-01

    A rare case of aortic arch aneurysm combined with chronic aortic dissection is reported. Because the visceral arteries originated from different, equivalently perfused lumens and the descending aorta was circumferentially calcified (porcelain aorta) limiting the possibilities of anastomosing, careful planning of the surgical strategy was of utmost importance. The complex surgery consisted of ascending and total arch replacement using the 'frozen elephant trunk' technique with Thoraflex™ Hybrid Prosthesis (Vascutek, Terumo, Inchinnan, Scotland); however, before insertion of the stent graft, an angioscopic resection of the dissection membrane in the proximal part of the descending aorta was carried out to ensure a complete expansion of the distal edge of the stent within the entire common lumen of the aorta and unimpaired distal flow in both lumens below the stent graft. The surgery and the postoperative course were uneventful. PMID:27002017

    Full Text Available Abstract A 48 year old man was transferred to our department with cardiogenic shock, pyrexia, a high white cell count and significant serum troponin T level. Clinical evaluation revealed severe mitral regurgitation secondary to a flail of both mitral valve leaflets. An emergency cardiac catheterisation did not reveal any significant coronary artery disease. Left ventricular angiogram and echocardiography demonstrated a good left ventricular function and massive mitral regurgitation. Blood cultures were negative for aerobics, anaerobics and fungi. The patient underwent emergency mitral valve replacement with a mechanical valve. Intraoperatively, the posteromedial papillary muscle was found to be ruptured. Histology of the papillary muscle revealed myocardial necrosis with no signs of infection. Cultures obtained from a mitral valve specimen were negative. The patient's recovery was uneventful and he was discharged on the 6th postoperative day.

    2010-01-01

    A large body of evidence indicates that the risk of developing chronic diabetic complications is under the control of genetic factors. Previous studies using a candidate gene approach have uncovered a number of genetic loci that may shape this risk, such as the VEGF gene for retinopathy, the ELMO1 gene for nephropathy, and the ADIPOQ gene for coronary artery disease. Recently, a new window has opened on identifying these genes through genome-wide association studies. Such systematic approach ...

  12. Duplication of hepatic artery

    Directory of Open Access Journals (Sweden)

    Saeed Muhammad

    2001-01-01

    Full Text Available Background: The hepatic arterial anatomy is aberrant in almost 33-41% of individuals. The variant arterial anatomy recognized during routine cadaveric dissection offers great learning potential. Such findings provide an alternative perspective to view common morphology and its structural and functional importance. These impart the concept of patient individuality and subsequent individualization of medical and surgical therapies. Adequate knowledge of normal and abnormal arterial anatomy is essential for peripancreatic surgery and liver transplantation. Aims of the study: To report on hepatic artery variations observed in the dissecting room and to find out the macroscopic pattern of varied human hepatic arterial vascularization by cadaveric dissection. Patients and Methods: Twenty human cadavers of caucasian origin were dissected to study the source and topographic pattern of hepatic arterial supply. Results: Nineteen cadavers exhibited typical hepatic arterial supply from the celiac axis. Only one female body out of twenty cadavers exhibited a dual arterial supply to all parts of liver and gallbladder. One artery originated from the celiac axis whereas the other was given off by the superior mesenteric artery. Conclusion: No doubt, aberrant hepatic vascularization should be assessed preoperatively by invasive and noninvasive techniques to avoid fatal complications, but we favour careful dissection over angiography as a means of defining the arterial anatomy.

    La séquence TRAP est une forme majeure et rare du syndrome transfuseur transfusé, caractérisée par l'absence de développement des structures cardiaques avec un spectre de malformations chez le fœtus transfusé qui n'est jamais viable et d'importantes complications touchant le jumeau transfuseur. Nous rapportons le cas d'une multipare admise avec expulsion en cours d'une présentation de siège, puis l'examen a trouvé une présentation irrégulière. Et à l’échographie une image hétérogène sans aire cardiaque ni organes fœtaux individualisables avec une seule masse placentaire sont visible, évoquant en premier un jumeau acardiaque. La voie basse a été acceptée, mais elle a présenté une hypercinésie évoquant un syndrome de prérupture. La césarienne a permis l'extraction d'une masse acardiaque. A travers ce cas, nous insistons sur l'intérêt du diagnostic prénatal de cette entité dans l'adaptation de la prise en charge, l'amélioration du pronostic du jumeau transfuseur ainsi que l’évitement du retard diagnostic et de ces conséquences.

    ça de incisura bilateral nas artérias uterinas entre a 24ª e a 26ª semana de gestação podem ser bons indicadores de complicações gestacionais e perinatais.PURPOSE: to determine the validity of uterine artery Doppler velocimetry for the prediction of pregnancy complications in a population of low-risk nulliparae. SUBJECTS: a prospective study was conducted on 45 patients in their first pregnancy with no history of chronic diseases. Uterine artery Doppler velocimetry was performed between 24 and 26 weeks, with the determination of resistance index (RI, pulsatility index (PI, S/D ratio, and the presence or absence of incisure in the flow velocity wave. Data were analyzed by the Mann-Whitney test for non-parametric samples, and the Fisher exact test was used in the evaluation of the qualitative parameters. RESULTS: pregnancy complications were observed in twelve patients, with four cases of preeclampsia, one case of small for gestational age newborn (SGA NB, one case of SGA NB + preterm delivery (PTD, three cases of PTD, one case of fetal centralization, and two cases of presence of thick meconium in the amniotic fluid at the time of pregnancy resolution. We noted that RI (median 0.56 x 0.68, PI (median 0.98 x 1.29 and S/D ratio (median 2.2 x 2.9 were higher at the examination performed between 24 and 26 weeks in patients with complications and did not differ in preeclampsia and SGA cases. The presence of bilateral incisure showed 100 and 90% sensitivity, 60.2 and 62.5% specificity, 29.4 and 42,9% positive predictive value (PPV, and 100 and 95.2% negative predictive value (NPV for the detection of preeclampsia or SGA and of any complication of pregnancy, respectively. An altered Doppler showed 83.3 and 83.3% sensitivity, 69.7 and 69.7% specificity, 33.3 and 50.0% PPV, and 95.8 and 92.0% NPV for the detection of preeclampsia or SGA and of any complication of pregnancy, respectively.

    Full Text Available Abstract A coronary arterial fistula is a connection between one or more of the coronary arteries and a cardiac chamber or great vessel. This is a rare defect and usually occurs in isolation. Its exact incidence is unknown. The majority of these fistulas are congenital in origin although they may occasionally be detected after cardiac surgery. They do not usually cause symptoms or complications in the first two decades, especially when small. After this age, the frequency of both symptoms and complications increases. Complications include 'steal' from the adjacent myocardium, thrombosis and embolism, cardiac failure, atrial fibrillation, rupture, endocarditis/endarteritis and arrhythmias. Thrombosis within the fistula is rare but may cause acute myocardial infarction, paroxysmal atrial fibrillation and ventricular arrhythmias. Spontaneous rupture of the aneurysmal fistula causing haemopericardium has also been reported. The main differential diagnosis is patent arterial duct, although other congenital arteriovenous shunts need to be excluded. Whilst two-dimensional echocardiography helps to differentiate between the different shunts, coronary angiography is the main diagnostic tool for the delineation of the anatomy. Surgery was the traditional method of treatment but nowadays catheter closure is recommended using a variety of closure devices, such as coils, or other devices. With the catheter technique, the results are excellent with infrequent complications. Disease name and synonyms Coronary arterial fistulas Coronary arterial fistulas or malformations

    2015-01-01

    The diver's nervous system is extremely sensitive to high ambient pressure, which is the sum of atmospheric and hydrostatic pressure. Neurological complications associated with diving are a difficult diagnostic and therapeutic challenge. They occur in both commercial and recreational diving and are connected with increasing interest in the sport of diving. Hence it is very important to know the possible complications associated with this kind of sport. Complications of the nervous system may result from decompression sickness, pulmonary barotrauma associated with cerebral arterial air embolism (AGE), otic and sinus barotrauma, high pressure neurological syndrome (HPNS) and undesirable effect of gases used for breathing. The purpose of this review is to discuss the range of neurological symptoms that can occur during diving accidents and also the role of patent foramen ovale (PFO) and internal carotid artery (ICA) dissection in pathogenesis of stroke in divers.

    Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation [13]. AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

    The incidence of infective endocarditis (IE) is thought to be around 4/100,000 person years in the general population, and 15/100,000 over the age of 50 years. The risk of acquiring IE is higher among patients with valvular heart disease (e.g., rheumatic valves, bicuspid aortic valves, myxomatous degeneration, etc.), congenital heart disease (e.g., coarctation, patent ductus arteriosus, ventricular septal defect, etc.), prosthetic cardiac valves, and among intravenous drug abusers. Staphylococcus aureus is one of the most common infective agents of IE, and most commonly originates from nosocomial sources, e.g., intravenous and arterial catheters, pacemaker leads, and prosthetic valves. Endocarditis caused by S aureus has a mortality rate of approximately 20% to 40%. In up to 40% of patients, IE caused by S aureus is associated with embolic complications. The risk of death increases with the development of complications. The epidemiology and microbiology of S aureus are changing rapidly, and resistance to antibiotics, especially methicillin, is becoming more widespread. In this review we will focus on the epidemiology, microbiology, and pathogenesis of S aureus IE, and also summarize the current guidelines for diagnosis, treatment, and prophylaxis of this clinical condition.

    True upper extremity peripheral artery aneurysms are a rarely encountered arterial disorder. Following computer-tomography angiographic (CT-a) imaging examination, true saccular aneurysm, originating from the left brachial artery was diagnosed in the 77-year-old female without history of trauma. The aneurysm was resected by surgical intervention, and primary repair of the brachial artery was performed by interposition of a part of great saphenous vein harvested from the left groin and creation of two end-to-end anastomoses between interposition graft and previously resected part of brachial artery. No complication was observed during the follow-up. Surgical intervention for upper extremity aneurysms should be initiated without delay. Factors combined with minimal morbidity associated with repair suggest that surgical repair should be performed routinely for true upper extremity arterial aneurysms. PMID:20865459

    Full Text Available Background. Hemobilia is a rare, jeopardizing complication of laparoscopic cholecystectomy coming upon usually within 4 weeks after surgery. The first-line management is angiographic coil embolization of hepatic arteries, which is successful in the majority of bleedings: in a minority of cases, a second embolization or even laparotomy is needed. Case Presentation. We describe the case history of a patient in which laparoscopic cholecystectomy was complicated 3 weeks later by massive hemobilia. The cause of haemorrhage was a pseudoaneurysm of a right hepatic artery branching off the superior mesenteric artery; this complication was successfully managed by one-stage angiographic embolization with full recovery of the patient.

    International Nuclear Information System (INIS)

    Objective: To probe in the CT features and values of CT in the diagnosis of pseudoaneurysm complicating pancreatitis. Methods: To retrospectively analyze the CT images of 6 patients with pseudoaneurysm complicating pancreatitis proved by surgery or DSA, emphasis was put on the location, diameter and CT features of the pesudoaneurysm. Results: There were 2 patients with pseudoaneurysm complicated with acute pancreatitis, and 4 with chronic pancreatitis. Of 6 patients, spleenic artery were involved in 2 patients, and the lesions were located in the region of body and tail of the pancreas, 2 gastroduodenal artery and 1 superior pancreaticoduodenal artery located in the pancreatic head region, 1 superior mesenteric artery located in the region of small mesenteric artery. The diameter of 6 lesions ranged from 3.2-7.0 cm with a mean diameter of 5.8 cm. All the pesudoaneurysm were round or ovary-shaped. In plain CT images, these lesions were presented with homogeneous or heterogeneous hypoattenuation. In contrast-enhanced CT images, the lesions were presented with pronounced enhancement which was similar to the CT attenuation value within the aorta, and peripheral nonenhanced margin within the lesions were observed. Conclusion: Contrast-enhanced CT scans were of great importance in the diagnosis of pseudoaneurysm complicating pancreatitis. (authors)

    Full Text Available Linezolid is the only antibiotic available as an oral formulation for resistant staphylococcal infections. It is effective in skin and soft tissue infections, nosocomial pneumonias including VAP, infective endocarditis and MRSA meningitis. It is also effective in the eradication of both nasal and throat colonization of MRSA. Its high bioavailability and post antibiotic effect, ease of switching to oral therapy during its use and the fact that it can be used in patients of all ages, also in patients with liver disease and poor kidney function and its increased effectiveness over glycopeptides makes this drug a precious drug in the treatment of resistant staphylococcal infections. Linezolid resistance in staphylococcus is defined as a linezolid MIC of and #8805;8 mg/L. Reported Linezolid resistance in India and elsewhere is 2-20%. There is clonal dissemination of Linezolid Resistant Staphylococcus aureus (LRSA within or across health care settings which demands continuous surveillance to determine the emergent risk of resistance strains and to establish guidelines for appropriate use. Clinical laboratories should confirm any LRSA preferably by a second method, prior to using linezolid for serious infections. Effective surveillance, more judicious use of this antibiotic, avoiding linezolid usage for empiric therapy in hospital acquired staphylococcus infections, optimization of the pharmacological parameters of the antibiotics in specific clinical situation, decreasing bacterial load by timely surgical debridement or drainage of collections, use of combination therapies would prevent the emergence of resistance to linezolid in staphylococcus aureus.

    Staphylococcus aureus is a dangerous pathogen that causes a variety of severe diseases. The virulence of S. aureus is defined by a large repertoire of virulence factors, among which secreted toxins play a preeminent role. Many S. aureus toxins damage biological membranes, leading to cell death. In particular, S. aureus produces potent hemolysins and leukotoxins. Among the latter, some were recently identified to lyse neutrophils after ingestion, representing an especially powerful weapon agai...

Materials and methods. From March 2007 till January 2013 421 patients: 230 men (54,6% and 191 women (45,4%; mean age 43,07 ± 11,62 undergone 429 kidney transplantations in the department of pancreas and kidney transplantation of the Scientific-Research Institute of Emergency Care named after N.V. Sklifosovsky. In order to evaluate the condition and the function of the kidney transplant ultrasound investigation (daily andacquisition(weekly wereused. In cases of kidney dysfunction and assumption of vessel complications we used computerized tomography. Besides, we used daily analysis of biochemical and clinical parameters of blood and urine. Results. The most common vessel complication was the thrombosis of the microvasculature of the kidney transplant due to acute humoral and combined rejection resistant to antirejection therapy (n = 9; 2,1%; in 4 cases there was a breakage of the transplant due to the acute rejection and the urgent transplantatectomy in an effort to save the patient; thrombosis of the transplantat artery occurred in 1 case (0,23%; we observed 2 cases (0,46% of the artery stenosis and 2 cases (0,46% of venous thrombosis. Conclusion. Summary frequency of vessel complications in our clinic, including thrombosis due to rejection, was 3,49%. It fully corresponds with data obtained from the global medical community. The incidence of great vessel thrombosis was less than 1% which indicates the adequate prophylactic anticoagulation therapy. For the benefit of early diacrisis of complications Doppler sonography is needed. In case of assumption of vessel complications urgent acquisition, computerized tomography and/ or angiography are to be held.

    To evaluate the feasibility and usefulness of the transradial approach for intra-arterial chemoembolization therapy in patients with hepatocellular carcinomas. Twenty-nine patients with hepatocellular carcinoma who underwent intra-arterial chemoembolization via the radial artery approach were involved in this study. All underwent Allen's test to check ulnar arterial patency. In all cases, we used the radial approach hepatic artery (RHA) catheter designed by ourselves, evaluating the selection ability of the hepatic artery using an RHA cathter, the number of punctures, the procedure time, and compression time at the puncture site as well as complications occurring during and after the procedure. Except for three in which puncture failure, brachial artery variation or hepatic artery variation occurred, all procedures were successful. The mean number of punctures was 3.5 and the average duration of the whole procedure was one and half hours. This gradually decreased as the number of procedures increased. The average duration at a compression of puncture site was 12 minutes. There were no major complications. Minor complications included minimal intimal dissection of the radial artery (3.8%), reversible vasospasm of the radial artery (7.7%), hematoma at a puncture site (7.7%) and transient neurologic deficit (3.8%). The transradial approach using an RHA catheter for intra-arterial chemoembolization theraphy in patients with hepatocellular carcinomas was technically feasible, with acceptable levels of safety. It may be a good alternative to absolute bed rest with a sand bag after the femoral approach.

    1999-01-01

    During essential and secondary arterial hypertension it is possible to observe changes in microcirculation perfusion associated with a reduction in tissue oxygenation due in part to hemorheological changes such as an increase in blood viscosity or the formation of the red blood cell "rouleaux" which favour an increase in peripheral resistance and can cause or worsen arterial hypertension. We studied 21 healthy subjects (11 male and 10 female aged 42 +/- 4) and 26 hypertensive subjects (14 male and 12 female aged 49 +/- 3). The patients were non smokers and non suffering from respiratory or haemathological pathologies. They were not undergoing antihypertensive or vasodilatory pharmaceutical treatment. The patients suffered from mild hypertension (II WHO) with Peripheral Occlusive Arterial Disease (POAD II "a" acc. to Leriche-Fontaine class.). The patients showed an increase in cholesterolaemia (6.42 +/- 0.81 mmol/l) and trygliceridaemia (2.73 +/- 0.09 mmol/l) at an average level. The patients were studied in standard conditions with a constant temperature of 22 degrees C. We measured SBP, DBP, MBP, and the HR. We also measured the elongation index (EI) (with shear stress range 0.30 to 30 pascals) using LORCA, acc. to Hardeman method (1994), in order to study the erythrocyte deformability and aggregation kinetics in dynamic condition. To evaluate deformability in static conditions we calculated the Erythrocyte Morphologic Index (EMI), acc. to Forconi method, via the bowl/discocyte ratio (for 100 red blood cells fixed in glutaraldehyde at 0.3% and observed with an optical microscope under immersion in glycerol). Peripheral oxygenation was taken transcutaneously (TcpO2). To establish the level of vascular disease we used the Regional Perfusion Index (RPI = TcpO2 foot/TcpO2 subclavean) and doppler guided Winsor Index (WI). The Student "t" test and linear regression were used for the statistical analysis. Our data confirm a reduction in peripheral tissue oxygenation in

    Full Text Available Abstract Background Endocarditis is a common complication in Staphylococcus aureus bacteremia (SAB. We compared risk factors, clinical manifestations, and outcome in a large, prospective cohort of patients with S. aureus endocarditis in injection drug users (IDUs and in nonaddicts. Methods Four hundred and thirty consecutive adult patients with SAB were prospectively followed up for 3 months. Definite or possible endocarditis by modified Duke criteria was found in 74 patients: 20 patients were IDUs and 54 nonaddicts. Results Endocarditis was more common in SAB among drug abusers (46% than in nonaddicts (14% (odds ratio [OR], 5.12; 95% confidence interval [CI], 2.65–9.91; P P P P = 0.03, and their SAB was more often community-acquired (95% vs 39%, P P P = 0.70. Arterial thromboembolic events and severe sepsis were also equally common in both groups. There was no difference in mortality between the groups at 7 days, but at 3 months it was lower among IDUs (10% compared with nonaddicts (39% (OR, 5.73; 95% CI, 1.20–27.25; P = 0.02. Conclusion S. aureus endocarditis in IDUs was associated with as high complication rates including extracardiac deep infections, thromboembolic events, or severe sepsis as in nonaddicts. Injection drug abuse in accordance with younger age and lack of underlying diseases were associated with lower mortality, but after adjusting by age and underlying diseases injection drug abuse was not significantly associated with mortality.

  13. Risks and complications in rhinoplasty

    Rettinger, Gerhard

    2007-01-01

    Full Text Available Rhinoplasty is regarded to be associated with many risks as the expectations of patient and physician are not always corresponding. Besides of postoperative deformities many other risks and complications have to be considered.Reduction-rhinoplasty e.g. can cause breathing disturbances which are reported in 70% of all revision-rhinoplasty-patients. One has to be aware however that scars and loss of mucosal-sensation can also give the feeling of a “blocked nose”. The main risks of autogenous transplants are dislocation and resorption, while alloplasts can cause infection and extrusion. In this respect silicone implants can have a complication rate between 5-20%. Less complications are reported with other materials like Gore-Tex. Complications of skin and soft tissues can be atrophy, fibrosis, numbness, cysts originating from displaced mucosa or subcutaneous granulomas caused by ointment material. Postoperative swelling depends mainly on the osteotomy technique. Percutaneous osteotomies cause less trauma, but may result in visible scars. Infections are rare but sometimes life-threatening (toxic-shock-syndrome. The risk is higher, when sinus surgery and rhinoplasty are combined. Osteotomies can also cause injuries of the orbital region. Necrosis of eye-lids by infections and blindness by central artery occlusion are known. There are reports on various other risks like rhinoliquorrhea, brain damage, fistulas between sinus-cavernosus and carotid artery, aneurysms and thrombosis of the cavernous sinus. Discoloration of incisors are possible by damage of vessels and nerves. Rhinoplasty can also become a court-case in dissatisfied patients, a situation that may be called a “typical complication of rhinoplasty”. It can be avoided by proper patient selection and consideration of psychological disturbances. Postoperative deformities are considered as main risks of rhinoplasty, causing revision surgery in 5% to 15% of the cases. The analysis of

    Staphylococcus aureus is a major pathogen that colonizes about 20% of the human population. Intriguingly, this Gram-positive bacterium can survive and thrive under a wide range of different conditions, both inside and outside the human body. Here, we investigated the transcriptional adaptation of S...... to their dependence on the RNA polymerase sigma factors SigA or SigB, and allow identification of new potential targets for several known transcription factors. In particular, this study revealed a relatively low abundance of antisense RNAs in S. aureus, where they overlap only 6% of the coding genes, and only 19...... antisense RNAs not co-transcribed with other genes were found. Promoter analysis and comparison with Bacillus subtilis links the small number of antisense RNAs to a less profound impact of alternative sigma factors in S. aureus. Furthermore, we revealed that Rho-dependent transcription termination...

    2016-01-01

    Vascular complications in patients with glioma most commonly include venous and arterial thromboembolism; however, treatment-induced vasculopathies are also problematic, especially in long-term survivors. The interactions between treatment such as radiation and chemotherapy, the coagulation cascade, endothelium, and regulators of angiogenesis are complex, drive glioma growth and invasion, and create common management problems in the clinic. We review the incidence of thrombotic complications in glioma, the biology of the coagulome as related to glioma progression, prevention and treatment of thrombosis, the role of anticoagulants as anticancer therapy, and vascular complications such as ischemic stroke and intracranial bleeding. The coagulation cascade is intimately involved in cancer-related thrombosis, glioma progression, and vascular complications of glioma therapy. Tissue factor is the principal initiator of coagulation and is upregulated in a glioma subtype-specific fashion. Short-term (perioperative) antithrombotic prophylaxis is effective, but long-term anticoagulation, although attractive, is not routinely indicated. Most patients with symptomatic venous thromboembolism can be safely anticoagulated, including those on anti-vascular endothelial growth factor therapeutics such as bevacizumab. Initial therapy should include low-molecular-weight heparin, and protracted anticoagulant treatment, perhaps indefinitely, is indicated. Many complex interactions resulting in vessel wall injury can lead to ischemic stroke, intracranial and intratumoral hemorrhage, and long-term sequelae such as cognitive impairment. PMID:26948359

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of angiography and cholangiography on the diagnosis and interventional treatment on vascular and biliary complications after liver transplantation. Methods: Sixteen of 46 patients (15 males, 1 female, 17-60 years old) after orthotopic liver transplantation received angiography due to abnormal ultrasonography or edema of lower limbs, or cholangiography due to progressing jaundice. 15 cases received angiography and proved vascular complications and 4 cases received cholangiography and biliary complications were found. 3 of them appeared both vascular and biliary complications. Results: Hepatic artery complication was the most common complication (seen in 9/16 patients), including hepatic artery thrombosis or stenosis (6/9), bleeding (2/9) and hepatic artery-dissecting aneurysm (1/9). One case with hepatic artery thrombosis received transcatheter thrombolysis and two cases with bleeding received coil embolization. Stenosis of inferior vena cava and portal vein were observed in 6 and 2 patients respectively. After balloon angioplasty or stent placement, clinical symptom of all cases alleviated. Biliary complications including biliary stricture and anastomotic bile leak occurred in 4 patients. Jaundice decreased after percutaneous transhepatic cholangiography and drainage. Conclusion: Interventional methods offered both diagnosis and mini-invasive treatment for patients after liver transplantation with vascular and biliary complications. Balloon angiography and stent placement of venous stenosis is an useful procedure for the treatment of these problems

    Culture supernatants from a number of Staphylococcus hyicus strains caused toxic effects to both murine fibroblast and porcine keratinocyte cells in culture. The extent of cytotoxicity was shown to differ between strains and may provide an indication of strain virulence. Purification of cytotoxic activity produced by S. hyicus (strain P119) using preparative isoelectric-focussing demonstrated it to be cytolytic, haemolytic and non-proteolytic. The cytotoxin demonstrates certain properties in common with the delta haemolysin of Staphylococcus aureus. PMID:2024438

  4. Intra-arterial port implantation for intra-arterial chemotherapy : comparison between PIPS(Percutaneously Implantable Port System) and port system

    International Nuclear Information System (INIS)

    To compare the techniques and complications of intra-arterial port implantation for intra-arterial chemotherapy between PIPS and the port system. For intra-arterial port implantation, 27 cases in 27 patients were retrospectively evaluated using PIPS(PIPS-200, William Cook Europe, Denmark) while for 21 cases in 19 patients a pediatric venous port system(Port-A-Cath, 5.8F, SIMS Deltec, U. S. A.) was used. All intra-arterial port implantation was performed percuteneously in an angiographic ward. Hepatocellular carcinoma was diagnosed in 18 patients and hepatic metastasis in 16. Peripheral cholangiocarcinoma, and pancreatic gastric, ovarian, renal cell and colon carcinoma were included. We compared the techniques and complications between PIPS and the port system. The follow up period ranged from 23 to 494(mean, 163) days in PIPS and from 12 to 431(mean, 150) days in the port system. In all cases, intra-arterial port implantations were technically successful. Port catheter tips were located in the common hepatic artery(n=8), proper hepatic artery(n=7), right hepatic artery(n=5), gastroduodenal artery(n=2), left hepatic artery(n=1), pancreaticoduodenal artery(n=1), inferior mesenteric artery(n=1), lumbar artery(n=1), and renal artery(n=1) in PIPS, and in the proper hepatic artery(n=6), gastroduodenal artery(n=6), common hepatic artery(n=3), right hepatic artery(n=4), inferior mesenteric artery(n=1), and internal iliac artery(n=1) in the port system. Port chambers were buried in infrainguinal subcutaneous tissue. Using PIPS, complications developed in seven cases(25.9%) and of these, four (57.1%) were catheter or chamber related. In the port system, catheter or chamber related complications developed in four cases(19.0%). Because PIPS and the port system have relative merits and demetrits, successful intra-arterial port implantation is possible if equipment is properly selected

    Full Text Available The most common anatomic variant seen in the donor kidneys for renal transplantation is multiple renal arteries (MRA, which can cause an increased risk of complications. We describe the long-term outcomes of 16 years of experience in 76 kidney transplantations with MRAs. In a new reconstruction technique, we remove arterial clamps after anastomosing the donor to the recipient′s main renal vessels, which cause backflow from accessory arteries to prevent thrombosis. By this technique, we reduce the ischemic times as well as the operating times. Both in live or cadaver donor kidneys, lower polar arteries were anastomosed to the inferior epigastric artery and upper polar arteries were anastomosed to the superior epigastric arteries. Injection of Papaverine and ablation of sympathic nerves of these arteries dilate and prevent them from post-operative spasm. Follow-up DTPA renal scan in all patients showed good perfusion and function of the transplanted kidney, except two cases of polar arterial thrombosis. Mean creatinine levels during at least two years of follow-up remained acceptable. Patient and graft survival were excellent. No cases of ATN, hypertension, rejection and urologic complications were found. In conclusion, this technique can be safely and successfully utilized for renal transplantation with kidneys having MRAs, and may be associated with a lower complication rate and better graft function compared with the existing techniques.

  8. Long-term outcomes of internal carotid artery disease treated using radial artery graft

    International Nuclear Information System (INIS)

    Complex internal carotid artery disease presents a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict occurrence of ischemic complications after internal carotid artery ligation. The present study concerns long-term clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2007, we performed radial artery grafting followed immediately by parent artery occlusion in 20 sides of 19 patients with complex internal carotid arteries disease with follow-up for more than 36 months (5 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative MRI and MR angiography (MRA) every year to assess graft patency, ischemic complications, and de novo aneurysm. Another 20 carotid aneurysms with visual disturbance were assessed concerning outcome. Among 13 patients with cranial nerve (III and VI) disturbances, all dysfunctions were improved in cases treated within 8 months of onset to operation. On the other hand, patients with second cranial nerve disturbances were not improved in cases treated after 4 months of onset. No long-term complications were discovered with MRI and MRA. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Long-term safety is satisfactory, with no delayed complications such as graft stenosis, ischemic complications or de novo aneurysm formations in follow-up periods of more than 3 years. Good clinical outcome of cranial nerve palsy was achieved in patients treated within 8 months of onset for cranial nerve (CN) III and VI, and 4 of CN II palsy. (author)

  9. Imaging and management of complications of central venous catheters

    International Nuclear Information System (INIS)

    Central venous catheters (CVCs) provide valuable vascular access. Complications associated with the insertion and maintenance of CVCs includes pneumothorax, arterial puncture, arrhythmias, line fracture, malposition, migration, infection, thrombosis, and fibrin sheath formation. Image-guided CVC placement is now standard practice and reduces the risk of complications compared to the blind landmark insertion technique. This review demonstrates the imaging of a range of complications associated with CVCs and discusses their management with catheter salvage techniques

    Eyelid surgery consists of challenging reconstructive and cosmetic procedures. Because of the complex anatomy and corresponding vital functions of the upper and lower eyelids, the avoidance of eyelid complications is of vital importance. Complications after eyelid surgery include basic complications (infection, granuloma) and vision-threatening complications. Preoperative history, physical examination, surgical planning, and meticulous surgical technique must be undertaken to prevent complications after eyelid surgery. In addition, patient knowledge, expectations, and motivations must be determined before surgery is performed. PMID:27105805

    The tentorial artery is often involved in arterial supply to tentorial dural fistulas. The hypertrophied tentorial artery is accessible to embolization, either with glue or with particles. Six patients are presented with tentorial dural fistulas, mainly supplied by the tentorial artery. Two patients presented with intracranial hemorrhage, two with pulsatile tinnitus and one with progressive tetraparesis, and in one patient the tentorial dural fistula was an incidental finding. Different endovascular techniques were used to embolize the tentorial artery in the process of endovascular occlusion of the fistulas. All six tentorial dural fistulas were completely occluded by endovascular techniques, confirmed at follow-up angiography. There were no complications. When direct catheterization of the tentorial artery was possible, glue injection with temporary balloon occlusion of the internal carotid artery at the level of the tentorial artery origin was effective and safe. Different endovascular techniques may be successfully applied to embolize the tentorial artery in the treatment of tentorial dural fistulas. (orig.)

    A 70-year-old man with a 3-year history of bronchiectasis presented with massive hemoptysis that had lasted for 3 days. In our attempt to perform bronchial artery embolization, upper abdominal angiography was required to locate the left bronchial artery, which in this case was of anomalous origin, arising from a replaced left hepatic artery, which arose from the left gastric artery-a very unusual anatomical variant. We performed embolization with polyvinyl alcohol particles, and the patient's symptoms resolved completely, with no additional complications after conservative treatment.

  17. Cerebral angiography in patients with complicated migraine

    International Nuclear Information System (INIS)

    38 patients (mean age: 29 years) were investigated by means of complete 4-vessel angiography: all of them were suffering from complicated migraine without detectable vascular malformation. Stenoses of the great craniocervical vessels were found in 11 patients (28.9%), but there was not a single case of vascular occlusion. A correlation between the localization of the stenosis, the localization of the headache and the presumed region of the transient cerebral function disturbance was found only in a few patients. Concerning the morphological changes of the small intracranial arterial branches, there was hardly an difference between clinically affected and non-affected territories of the middle cerebral artery. The angiograms of the 38 cases of complicated migraine were compared with the angiograms of 40 patients suffering from strokes in the young and those of 49 patients with transient ischaemic attacks. There were remarkably fewer stenoses or occlusions in the great craniocervical arteries of patients suffering from complicated migraine (28.9%) than in the vessels of cases of stroke in the young (52.5%). However, the incidence was comparable with the results in patients with transient ischaemic attacks (34.7%). The degree of morphological changes in the small intracranial arterial branches is likely to depend primarily on the patient's age and less on the diagnosis. The results suggest that in almost 30% of patients with complicated migraine - even at juvenile age-stenoses of the great craniocervical vessels might be found. However, considering the fact that most of the stenoses are without haemodynamic significance and their localization is not in agreement with the clinical data, the pathogenetic value of these vessel wall changes is highly questionable.

    2011-01-01

    Background At present, revascularization is still one of the most critical technologies in orthotopic liver transplantation (OLT). Hepatic artery (HA) variations occur frequently in both donors and recipients. Moreover, there are always some pathological changes in the recipient hepatic artery. If handled improperly, it may cause complications after anastomosis.Therefore, arterial conduit could be used in primary OLT, re-OLT and multiple-OLT. This study aimed to investigate the indications, methods and techniques with usage of arterial conduit for HA revascularization during adult OLT.Methods We reviewed 1200 patients of consecutive OLTs performed during 2000-2009 in the First Affiliated Hospital of Sun Yat-sen University. Of these patients, 48 recipients with artery variations received HA revascularization with usage of arterial conduit and special postoperative managements. The indications, methods, techniques, and the managements of postoperative complications in adult OLT with usage of arterial conduit for HA revascularization were analyzed.Results In 48 cases with artery bypass, the arterial conduit were anastomosed between donor hepatic artery and recipient infrarenal aorta (n=32), between donor hepatic artery and recipient suprarenal aorta (n=10), and between donor upper abdominal organ cluster artery and recipient suprarenal aorta (n=6). The technique was applied in 4% (48/1200 cases) of the whole OLTs performed in the same period, and the patency rate of the conduits was 100%. Forty patients (83.3%) survived, and the average survival time was 3.9 years. Eight patients (16.7%) died (all due to tumor recurrence),while the average survival time was 1.2 years. All these patients have not experienced artery-related complications in their survival time.Conclusions When recipient HA has variations or pathological changes in OLT, the donor artery should be anastomosed to recipient abdominal aorta with an arterial conduit to achieve satisfactory outcomes

A 41-year-old woman was admitted at the emergency room of our hospital with massive gastrointestinal bleeding. A total gastrectomy was performed. During the postoperative period in the intensive care unit , the patient maintained hemodynamic instability. Invasive hemodynamic monitoring with a pulmonary artery catheter was then indicated. During the maneuvers to insert the catheter, a true knot formation was identified at the level of the superior vena cava. Several maneuvers by radiological endovascular invasive techniques allowed removal of the catheter. The authors describe the details of this procedure and provide comments regarding the various techniques that were employed in overcoming this event. A comprehensive review of evidence regarding the benefits and risks of pulmonary artery catheterization was performed. The consensus statement regarding the indications, utilization, and management of the pulmonary artery catheterization that were issued by a consensus conference held in 1996 are also discussed in detail.É relatada uma complicação infreqüente , associada ao uso do Cateter de Artéria Pulmonar.

  14. Selective catheterization of the brachiocephalic arteries via the right brachial artery

    International Nuclear Information System (INIS)

    Selective intra-arterial digital subtraction angiography of the brachiocephalic arteries using the right brachial artery approach was successfully performed for 169 of 173 patients, 33 of whom were outpatients. Catheterization was unsuccessful for four patients; two of them elderly hypertensive men with tortuos brachial arteries, and two of them middle-aged obese women for whom arterial puncture could not be performed. 4-F modified Simmons type catheters were used in this study. Selective catheterizations of both common carotid arteries were successfully performed in all but one patient, a woman whose aberrant right subclavian artery prevented bilateral common carotid arterial catheterizations. Selective catheterizations of the right vertebral and left subclavian arteries, though relatively difficult, were successfully performed in 84.2% and 93.9% of patients, respectively. The mean examination time for a four-vessel study was 24.3 min. No major complications were encountered. Thus, transbrachial selective catheterization of the brachiocephalic arteries proved to be safe, useful, and relatively easy to perform. (orig.)

    This paper presents a review of various complications of multifetal gestations identified on MR imaging and highlights findings of those complications unique to monochorionic twinning. The goal is to illustrate the potential of MR as a useful application in these clinical circumstances. A total of 32 women with multifetal gestations and suspected complication detected initially by US underwent T2-weighted MR imaging. Additional T1-weighted images were obtained when intracranial hemorrhage was suspected. MR and US findings were compared in all cases. Of 32 cases, six demonstrated fetal complications specific to monochorionic twinning; the findings consisted of conjoined twins (n=2), twin-twin transfusion syndrome (n=1), co-twin demise with embolic disease (n=2), and twin-reversed arterial perfusion. (TRAP) syndrome (n=1). MR imaging confirmed US findings in all cases and was particularly helpful in delineating the extent of intracranial complications of monochorionic twins. The technique also showed improved anatomical detail in cases of conjoined twins. MR imaging provided additional information in cases of complicated monochorionic twinning, making it a useful complementary technique when combined with initial sonographic assessment. (orig.)

    To our knowledge, coronary bypass for complications of coronary artery disease in achondroplasia has not previously been described. Achondroplasia, in and of itself, is not a contraindication to coronary bypass. Although the anatomic reserve of saphenous vein is less in achondroplastic dwarfs than in people of normal stature, that vessel and the internal mammary artery can be harvested in routine fashion. A 60-year-old woman with several risk factors for coronary artery disease underwent succ...

  9. Complications of mechanical ventilation

    2011-01-01

    Full Text Available Mechanical ventilation of the lungs, as an important therapeutic measure, cannot be avoided in critically ill patients. However, when machines take over some of vital functions there is always a risk of complications and accidents. Complications associated with mechanical ventilation can be divided into: 1 airway-associated complications; 2 complications in the response of patients to mechanical ventilation; and 3 complications related to the patient’s response to the device for mechanical ventilation. Complications of artificial airway may be related to intubation and extubation or the endotracheal tube. Complications of mechanical ventilation, which arise because of the patient’s response to mechanical ventilation, may primarily cause significant side effects to the lungs. During the last two decades it was concluded that mechanical ventilation can worsen or cause acute lung injury. Mechanical ventilation may increase the alveolar/capillary permeability by overdistension of the lungs (volutrauma, it can exacerbate lung damage due to the recruitment/derecruitment of collapsed alveoli (atelectrauma and may cause subtle damages due to the activation of inflammatory processes (biotrauma. Complications caused by mechanical ventilation, beside those involving the lungs, can also have significant effects on other organs and organic systems, and can be a significant factor contributing to the increase of morbidity and mortality in critically ill of mechanically ventilated patients. Complications are fortunately rare and do not occur in every patient, but due to their seriousness and severity they require extensive knowledge, experience and responsibility by health-care workers.

However, a few of these children have lesions of focal segmental glomerulosclerosis, suffer from severe and prolonged proteinuria, and are at high risk for complications. Complications of NS are divided into two categories: disease-associated and drug-related complications. Disease-associated complications include infections (e.g., peritonitis, sepsis, cellulitis, and chicken pox, thromboembolism (e.g., venous thromboembolism and pulmonary embolism, hypovolemic crisis (e.g., abdominal pain, tachycardia, and hypotension, cardiovascular problems (e.g., hyperlipidemia, acute renal failure, anemia, and others (e.g., hypothyroidism, hypocalcemia, bone disease, and intussusception. The main pathomechanism of disease-associated complications originates from the large loss of plasma proteins in the urine of nephrotic children. The majority of children with MCNS who respond to treatment with corticosteroids or cytotoxic agents have smaller and milder complications than those with steroid-resistant NS. Corticosteroids, alkylating agents, cyclosporin A, and mycophenolate mofetil have often been used to treat NS, and these drugs have treatment-related complications. Early detection and appropriate treatment of these complications will improve outcomes for patients with NS.

    Full Text Available BACKGROUND The increasing global prevalence of nephrolithiasis continues to burden the health care delivery systems of developing nations. Percutaneous Nephrolithotomy (PCNL is considered the standard treatment for many types of calculi. This study focuses on the complications of PCNL in private practice setting at a peripheral center using the modified Clavien system and role of Guy’s stone score as a predictor of stone free rate and complications. METHODS This is a prospective cohort study of 480 patients who underwent PCNL during August 2011 to July 2015. The complications were classified according to modified Clavien system and correlated with the stone complexity as per the Guy’s stone score. RESULTS It was found that overall 120 complications were reported in 480 patients with the incidence of complications of Grade I, II, IIIa, IIIb, IVb being 48 (10%, 38 (7.9%, 15 (3.5%, 12 (2.5% and 4 (0.8% respectively. As per the Guy’s stone score there were 336, 104 and 40 cases belonging to GSS I, II and III respectively. All grades of complications were more common in GSS II and III. The stone clearance was found to be complete in 95%, 82% and 75% of GSS I, II, III respectively. CONCLUSION The stone complexity is related to complication rate and GSS helps to predict stone free rate and complications

    2006-05-01

    All simple arthroscopic procedures during 1999 through 2001 performed at Baerum community hospital were retrospectively examined. Procedures were excluded when being part of more complex procedures. A total of 876 procedures performed on 785 patients were left for examination. Complications were registered from the patient record and all received a written questionnaire or phone call. The answer was obtained from 97.6%. The overall complications rate was low, giving total of 5.00%. A total of 0.68% of the complications had therapeutic consequences. There were two superficial infections, one thromboembolic event/pulmonary embolus and one reoperation due to scar tissue. Other complications were considered minor, and had none or little consequence for the patient comprising preoperative bradycardial episodes, asthmatic events, subcutaneous infusion of total intravenous anaesthetics (TIVA), instrument breakage and conversion to arthrotomi. Postoperatively registered complications included swelling, haemarthros, portal bleeding and fistulation, temporary sensory loss and longstanding pain. Duration of surgery was the only predicting factor for postoperative complications. Simple arthroscopic surgery is safe and has few serious complications. The use of TIVA or tourniquet does not increase the morbidity or complication rate, and prophylaxis against thromboembolism was not necessary. PMID:16208459

    Innominate artery injury is a rare, but catastrophic complication of tracheostomy. We present a case of severe hemorrhagic shock in a 79-year-old male with innominate artery injury that occurred during tracheostomy. Despite temporary innominate artery isolation, the regional forehead saturation was 60 % without laterality. Because adequate cerebral blood flow was apparently maintained through collateral flow, we ligated the innominate, right carotid, and subclavian arteries. We confirmed adequate blood flow to the brain and the right subclavian artery through collateral circulation after ligation using computed tomographic angiography. A damage control management, which involves ligating the injured innominate artery to arrest hemorrhage and monitoring regional forehead saturation for brain ischemia, can be a considerable procedure for the treatment of severe hemorrhagic shock due to innominate artery injury.

    Full Text Available Chronic kidney disease (CKD is associated with increased cardiovascular risk. CKD is characterized by accelerated aging of vessels in which the age-related arterial stiffness increase is exacerbated by a number of uremia-related processes. Increased arterial stiffness is associated with structural and functional disorders, as well as with the increase in cardiovascular mortality in patients with CKD. Increased arterial stiffness is diagnosed at an early stage of CKD. Modern understanding of the mechanisms of increased risk of cardiovascular complications in CKD, the factors contributing to the loss of elasticity of the arteries, arterial stiffness increase consequences are analyzed. Data illustrating the twoway interaction between CKD and arterial stiffness and mechanisms of accelerated progression of arterial stiffness in CKD are presented.

    Takayasu arteritis (TA) is a rare, systemic, chronic inflammatory, progressive, idiopathic disease of aorta and its main branches. It causes narrowing, occlusion and aneurysm of arteries. It affects mainly young females in about 80-90% of cases (young female arteritis). TA has adverse effect on pregnancy in the form of abortion, superimposed preeclampsia, IUGR (Intrauterine growth restriction), IUFD (intrauterine fetal death), abruption and CCF (congestive cardiac failure). Careful assessment, treatment of TA complication, regular antenatal followup and multidisciplinary approach involving obstetrician, cardiologist, rheumatologist and anaesthetist improve maternal and fetal outcome. We described here a case of pregnancy with TA with bilateral renal artery stenosis and left subclavian artery stenosis. PMID:26500964

    The complications of pancreatitis, such as pseudocyst or abscesses, are well known to radiologists. Yet formation of a pseudoaneurysm of the short gastric artery is an uncommon complication of acute pancreatitis. It is also very rare for a psuedoaneurysm of the short gastric artery to cause splenic vein occlusion and the final result is gastric varices. We report here on a case that showed the dramatic effect of embolotherapy for a pseudoaneurysm of the short gastric artery that caused gastric variceal bleeding

    Pathologic myopia (PM) is one of the leading causes of visual impairment worldwide. The pathophysiology of PM is not fully understood, but the axial elongation of the eye followed by chorioretinal thinning is suggested as a key mechanism. Pathologic myopia may lead to many complications such as chorioretinal atrophy, foveoschisis, choroidal neovascularization, rhegmatogenous retinal detachment, cataract, and glaucoma. Some complications affect visual acuity significantly, showing poor visual prognosis. This article aims to review the types, pathophysiology, treatment, and visual outcome of the complications of PM.

  2. Imaging of osteochondroma complications

    International Nuclear Information System (INIS)

    Osteochondroma is the most common entity beyond all the known osseous tumors. It is a lesion with a high enlargement capacity and a continuous growing in some cases, and it may determine complications, mainly due to mass effect. It may be present in a solitary or multiple forms, and the last one is related with a higher tendency to sarcomatous transformation, which is the most frightening complication. The purpose of the present study is to demonstrate, through an iconographic assay, the most common complications caused by the osteochondromas, making the correlation of its clinical and radiological aspects.

    Objective To explore the causes, prevention, and management of the complications during intracranial aneurysm embolization with controllable coils (mechanical detachable spiral, MDS; and Guglielmi detachable coil, GDC). Methods Retrospective review of 120 cases with 125 intracranial aneurysms embolized with controllable coils from March 1995 to July 1999 was conducted. The 20 accidents (in 18 cases) including aneurysm rupture, over-embolization, protrusion of coil end into the parent artery, and thrombosis of the parent artery were analyzed. Results Among the 20 accidents, there were 6 aneurysm ruptures, 6 over-embolizations (in 5cases), 6 coil protrusions, and 2 thromboses (one was secondary to coil protrusion). The embolizationrelated mortality was 3.33% (4/120), the permanent neurological deficit was 1.67% (2/120), and the transitory neurological deficit was 3.33% (4/120). The occurrence and outcome of the complications were related to the embolizing technique, the pattern of aneurysm and its parent artery, the imperfection of embolic materials, and the observation and management during embolization. Conclusion Skilled embolizing technique, better understanding of the angio-anatomy of an aneurysm and its parent artery, correct judgement and management during embolization, and improvement of embolic materials are beneficial to the reduction of complications and to the melioration of the outcome of complications.

    Full Text Available The variation in origin of the testicular artery is not uncommon, few reports about a high origin from the abdominal aorta exist in the literature. The renal artery is known to exhibit variations in its number and position. The knowledge of this variation will help the radiologists and surgeons in avoiding clinical complication during interventions. During routine dissection teaching to first year MBBS students at Sapthagiri Medical College, Bangalore we found variation in vascular pattern of testicular and renal artery associated with renal cyst. Photographs of the variations were taken. There was high origin of left testicular artery and accessory left renal artery associated with bilateral simple renal cyst in adult Male cadaver aged around 60years.There was also prehilar division of right renal artery associated with renal cyst. Anomalies in the origin, course and number of testicular artery were observed in 4.7 percent of cases. Additional renal vessels are known as the accessory renal artery and their incidence varies between 9-76%. In the present case there was high origin of left testicular artery associated with accessory renal artery and renal cyst. This anatomical knowledge of the presence of accessory renal artery and high origin of testicular artery in this case is important for radiologists, surgeons and urologist in their clinical practice.

    2016-07-01

    Arthroscopy of the foot and ankle is a common orthopedic procedure with low complication rates. Arterial injuries from these procedures are an even more rare subset of the complications. Hemophilia A is a genetic disorder of aberrant coagulation, which leads to increased risk of bleeding even after minor trauma. We present the second case of anterior tibial artery pseudoaneurysm formation secondary to ankle arthroscopy in a hemophiliac patient and suggest that these individuals are at higher risk for developing complications associated with arterial injury. Furthermore, potential risk factors include port placement, anatomic variation of the vessels, and nature of the arthroscopic procedure. We recommend steps to prevent complications in hemophiliac patients. PMID:27174350

    2011-01-01

    Full Text Available In the United States, circumcision is a commonly performed procedure. It is a relatively safe procedure with a low overall complication rate. Most complications are minor and can be managed easily. Though uncommon, complications of circumcision do represent a significant percentage of cases seen by pediatric urologists. Often they require surgical correction that results in a significant cost to the health care system. Severe complications are quite rare, but death has been reported as a result in some cases. A thorough and complete preoperative evaluation, focusing on bleeding history and birth history, is imperative. Proper selection of patients based on age and anatomic considerations as well as proper sterile surgical technique are critical to prevent future circumcision-related adverse events.

    Addiction is a chronic relapsing disorder characterized by repetitive and compulsive drug-seeking behavior and drug abuse despite negative health or social consequences. Cocaine addiction is a significant worldwide public health problem, which has somatic, psychological, psychiatric, socio-economic and judicial complications. Some of the most frequent complications are cardiovascular effects (acute coronary syndrome, cardiac arrhythmias, increased blood pressure); respiratory effects (fibrosis, interstitial pneumonitis, pulmonary hypertension, alveolar haemorrhage, asthma exacerbation; emphysema), neurological effects (strokes, aneurysms, seizures, headaches); risk for contracting HIV/AIDS, hepatitis B and C, sexual transmitted disease and otolaryngologic effects. Other complications are not discussed here. The vast majority of studies indicate that there are cognitive deficits induced by cocaine addiction. Attention, visual and working memories, executive functioning are affected in cocaine users. Psychiatric complications found in clinical practice are major depressive disorders, cocaine-induced paranoia, cocaine-induced compulsive foraging and panic attacks. PMID:19642439

  18. On complicity theory.

    Science.gov (United States)

    Kline, A David

    2006-04-01

    The received account of whistleblowing, developed over the last quarter century, is identified with the work of Norman Bowie and Richard DeGeorge. Michael Davis has detailed three anomalies for the received view: the paradoxes of burden, missing harm and failure. In addition, he has proposed an alternative account of whistleblowing, viz., the Complicity Theory. This paper examines the Complicity Theory. The supposed anomalies rest on misunderstandings of the received view or misreadings of model cases of whistleblowing, for example, the Challenger disaster and the Ford Pinto. Nevertheless, the Complicity Theory is important for as in science the contrast with alternative competing accounts often helps us better understand the received view. Several aspects of the received view are reviewed and strengthened through comparison with Complicity Theory, including why whistleblowing needs moral justification. Complicity Theory is also critiqued. The fundamental failure of Complicity Theory is its failure to explain why government and the public encourage and protect whistleblowers despite the possibility of considerable harm to the relevant company in reputation, lost jobs, and lost shareholder value.

    Cavezzi, A; Parsi, K

    2012-03-01

    Foam sclerotherapy may result in drug and/or gas-related complications of a generalized or localized nature. Significant complications include anaphylactic/anaphylactoid reactions (very rare), deep vein thrombosis (1-3%), stroke (0.01%), superficial venous thrombosis (4.4%), tissue necrosis (variable frequency), oedema (0.5%) and nerve damage (0.2%). Cosmetic complications include telangiectatic matting (15-24%) and pigmentation (10-30%). Patent foramen ovale and other cardio-pulmonary right-to-left shunts seem to play a role in the systemic gas-related complications. In conclusion, foam sclerotherapy is characterized by an overall high degree of safety, though special attention should be given to the embolic and thrombotic complications. Good technique, adequate imaging, general precautions and compliance with post-treatment instructions may help avoid some of the adverse events and an appropriate early intervention may minimize possible sequelae. Higher volumes of sclerosant foam have been attributed to local and distant thrombotic complications and should be avoided. PMID:22312067

    2012-01-01

    Neurologic complications after roller coaster rides are uncommon but potentially catastrophic. Physicians should have a high index of suspicion and prompt appropriate investigation. A 22-year-old healthy African American man presented with a 2-day history of constant occipital headache associated with vertigo, nausea, vomiting, and ambulatory dysfunction. Physical examination showed gait ataxia, slight dysmetria, and vertical nystagmus. Magnetic resonance imaging (MRI) of the brain showed early subacute ischemic infarct in the right cerebellum in the distribution of the right posterior inferior cerebellar artery. Magnetic resonance angiography of the neck showed focal dissection of the right vertebral artery at C1 through C2 level. On subsequent questioning, the patient recollected riding a roller coaster 2 weeks before the onset of symptoms. Anticoagulation with heparin was started, and the patient was bridged to oral warfarin. After a 5-day uneventful hospital course, symptoms improved and patient was discharged on oral anticoagulation. Cervicocephalic arterial dissections after roller coaster rides are rarely described in literature. The acceleration and abrupt changes of direction might lead to indirect trauma that is applied to mobile portions of the cervicocephalic arteries leading to intimal tears. Magnetic resonance angiography combined with axial T1-weighted cervical MRI is preferred because it is a high-sensitive, noninvasive test. The rationale for the use of anticoagulants or antiplatelets in patients with cervicocephalic arterial dissection is to prevent early recurrence and infarction. However, a meta-analysis failed to show significant difference in the rates of disability or death between both groups. Therefore, the decision for medical treatment should be made in a case-by-case basis. PMID:20980120

    Angiography is essential for the detection of bleeding vessels in traumatic vascular injury. Immediately after the diagnosis, transcatheter embolization can be performed for the control of bleeding effectively and easily with proper use of embolic materials. Transcatheter embolization is believed to be the treatment of choice when emergency control is needed, where surgical approach is difficult and in those who are poor candidate for surgery. We have tried bleeding control in 18 cases of trauma over recent 4 years. The results were as follows; 1. Causes of bleeding(cases): Blunt or penetrating trauma (10), latrogenic trauma (8), (Postoperative (5), Needle biopsy (2), Percutaneous hepatic procedure (1)) 2. Embolized vessels: Renal artery branches (8), Hepatic artery branches (2), Arteries supplying chest wall (2), External carotid artery branches (3), Internal carotid artery (1), Circumflex humeral artery (1), Internal iliac artery branches (1). 3. Embolic agents: Gelfoam cubes (16), Stainless steel coils (3), Detachable latex balloon (1). 4. Successful bleeding control was achieved in 17 cases and reduction of the amount of bleeding in one case without significant complications.

    Systemic arterial air embolism is a rarely encountered but much feared complication of percutaneous lung biopsy. We present a comprehensive review of iatrogenic air embolism post-lung biopsy, a complication that is often suboptimally managed. This review was inspired by our own institutional experience and we use this to demonstrate that excellent outcomes from this complication can be seen with prompt treatment using hyperbaric oxygen chamber therapy, after initial patient stabilization has been achieved. Pathophysiology, clinical features, and risk factors are reviewed and misconceptions regards venous versus arterial air embolism are examined. An algorithm is provided for radiologists to ensure suspected patients are appropriately managed with more favourable outcomes.

    We introduce here our case of a 4-cm, large saccular aneurysm in a patient with right flank pain that was treated by placement of a stent-graft via the left brachial artery. The large renal artery aneurysm was successfully occluded without any permanent sequela, although there were several complications that included intraprocedural renal arterial thrombosis, occlusion of the posterior segmental artery, a small thromboembolism in the left pons and a small arteriovenous fistula in the brachial artery. Stent-graft placement for treatment of renal arterial aneurysm is an effective and safe procedure, but the operator has to be cautious not to induce complications in case of using the brachial arterial approach.

  8. Inducible Clindamycin Resistance in Staphylococcus Species

    International Nuclear Information System (INIS)

    Objective: To determine the frequency of inducible clindamycin resistance in clinical isolates of Staphylococcus species by phenotypic D-test. Study Design: Observational study. Place and Duration of Study: Ziauddin University Hospital, Karachi, from July to December 2011. Methodology: Consecutive clinical isolates of Staphylococcus species were collected and identified by conventional microbiological techniques. Antimicrobial susceptibility testing and inducible clindamycin resistance was carried out by performing D-test using CLSI criteria. Methicillin resistance was detected by using Cefoxitin disk as a surrogate marker. Statistical analysis was performed by SPSS version-17. Results: A total of 667 clinical isolates of Staphylococcus species were obtained during the study period. In these isolates, 177 (26.5%) were Staphylococcus aureus, and 490 (73.5%) were coagulase negative Staphylococci. The total frequency of inducible clindamycin resistance among isolates of Staphylococcus species was 120/667 (18%). Frequency of inducible clindamycin resistance among coagulase negative Staphylococci group and Staphylococcus aureus group were 18.57% and 16.38% respectively. Median age of patients in D-test positive group was 19.5 (1 - 54) years. Conclusion: The frequency of inducible clindamycin resistance among Staphylococcus species may differ in different hospital setup. Clinical microbiology laboratories should implement testing simple and effective D-test on all Staphylococcus species. D-test positive isolates should be reported clindamycin resistant to decrease treatment failure. (author)

  9. Avoiding complications in radical neck dissection

    International Nuclear Information System (INIS)

    As reported previously, it remains our conclusion that the radical neck dissection can be performed expediently in a reasonable period of time, usually without the need of blood replacement, and is not characterized by major physiologic disability or wound complications secondary to the neck dissection alone. The presence of preoperative radiation, composite resections entering the oral cavity or pharynx, and systemic disease or debilitation, however, vastly enhance the risk of significant life threatening complications and prolong hospitalization; therefore, the use of post-operative radiation therapy in combined treatment, the use of planned fistulas and generally accepted reconstructive techniques, and a careful evaluation of the methods and technique for protection of the carotid artery are recommended

    Although surgical site infections (SSI) in dermatologic operative procedures are extremely rare, it is important to understand risks and etiological factors to initiate risk assessment and specific preventive measures. SSI commonly are associated with a complicated, long-term and expensive outcome. Typical wound pathogens of these infections include a variety of multiresistant organisms along with Staphylococcus aureus, Staphylococcus epidermidis, hemolytic streptococci and the gram-negative bacilli Escherichia coli and Pseudomonas aeruginosa. Effective hygienic measures as part of an adequate quality management system should consider the critical points in the development of SSI, particularly in the setting of an outpatient dermatologic unit, such as preparation of the operative area, preoperative skin antisepsis, hand hygiene, safe and skilled technique by surgeons, and barrier nursing to prevent spread of pathogens. The baseline infection incidence in dermatologic surgery inherently is low; nevertheless significant improvements can be achieved by implementation of risk-adapted infection control measures.

    Endovascular renal artery stent therapy for atherosclerotic renal artery stenosis (RAS) is associated with excellent acute technical success, low complication rates and acceptable long-term patency. However, the clinical benefits to patients of renal artery stenting remain uncertain. To facilitate debate regarding the treatment of RAS, we need to understand the epidemiology, basic physiology and clinical consequences of renal artery stenosis. We must attempt to determine which patients are likely to benefit from renal artery stenting, assess the nuances of the percutaneous procedure and review the current literature pertaining to renal artery stenting.

  12. Incretin-Based Therapy for Prevention of Diabetic Vascular Complications

    2016-01-01

    Full Text Available Diabetic vascular complications are the most common cause of mortality and morbidity worldwide, with numbers of affected individuals steadily increasing. Diabetic vascular complications can be divided into two categories: macrovascular and microvascular complications. Macrovascular complications include coronary artery disease and cerebrovascular disease, while microvascular complications include retinopathy and chronic kidney disease. These complications result from metabolic abnormalities, including hyperglycemia, elevated levels of free fatty acids, and insulin resistance. Multiple mechanisms have been proposed to mediate the adverse effects of these metabolic disorders on vascular tissues, including stimulation of protein kinase C signaling and activation of the polyol pathway by oxidative stress and inflammation. Additionally, the loss of tissue-specific insulin signaling induced by hyperglycemia and toxic metabolites can induce cellular dysfunction and both macro- and microvascular complications characteristic of diabetes. Despite these insights, few therapeutic methods are available for the management of diabetic complications. Recently, incretin-based therapeutic agents, such as glucagon-like peptide-1 and dipeptidyl peptidase-4 inhibitors, have been reported to elicit vasotropic actions, suggesting a potential for effecting an actual reduction in diabetic vascular complications. The present review will summarize the relationship between multiple adverse biological mechanisms in diabetes and putative incretin-based therapeutic interventions intended to prevent diabetic vascular complications.

    Tattoos are defined as the introduction of exogenous pigments into the dermis in order to produce a permanent design. This process may occur unintentional or may be deliberately administered for cosmetic or medical reasons. Tattoos have been around for over 5000 years and over time have evolved to represent a common cosmetic practice worldwide. Currently, adverse reactions are relatively rare and generally unpredictable and predominantly include immune-mediated reactions and skin infections. Along with better healthcare standards and more stringent public health mandates such as the provision of disposable needles, major infectious complications related to hepatitis and human retroviral infections have decreased significantly. When they do occur, skin infections are most frequently associated with Staphylococcus aureus or Streptococcus pyogenes. The aim of this study is to review the types and rates of medical complications of permanent tattoos. PubMed search and search dates were open ended. Acute local inflammation is the most common complication, but infections, allergic contact dermatitis, and other inflammatory or immune responses that are not well-characterized may occur. As many patients with immune reactions to tattoos do not react on skin or patch testing, it is postulated that the antigens contained in dyes or pigments are such small molecules that they need to be haptenized in order to become immunogenic. Red ink is associated more frequently with long-term reactions, including granulomatous and pseudolymphomatous phenomena or morphea-like lesions and vasculitis. Exacerbation of preexisting psoriasis, atopic dermatitis, and pyoderma gangrenosum may occur after tattooing. There is no well-defined association between cancer and tattoos. The treatment of tattoo-related complications may include local destructive measures (cryotherapy, electro-surgery, dermabrasion, chemical destruction, ablative laser destruction), surgical excision, and thermolysis of the

    Purpose: This study was designed to evaluate the safety of chemotherapeutic infusion or chemoembolization by way of the cystic artery in patients with hepatocellular carcinoma (HCC) supplied exclusively by the cystic artery. Methods: Between Jan 2002 and Dec 2011, we performed chemotherapeutic infusion or chemoembolization using iodized oil for the treatment of 27 patients with HCC supplied exclusively by the cystic artery. Computed tomography (CT) scans, digital subtraction angiograms, and medical records were retrospectively reviewed by consensus. Results: The cystic artery originated from the main right hepatic artery in 24 (89 %) patients, from the right anterior hepatic artery in 2 (7 %) patients, and from the left hepatic artery in 1 (4 %) patient. Selective catheterization of the cystic artery was achieved in all patients. Superselection of tumor-feeding vessels from the cystic artery was achieved in 7 patients (26 %). Chemotherapeutic infusion was performed in 18 patients (67 %), and chemoembolization was performed in 9 patients (33 %). There were no major complications and only 2 minor complications, including vasovagal syncope and nausea with vomiting. Individual tumor response supplied exclusively by the cystic artery at the follow-up enhanced CT scan were complete response (n = 16), partial response (n = 3), and stable disease (n = 8). Conclusion: HCC supplied exclusively by the cystic artery can be safely treated without severe complications by chemotherapeutic infusion or chemoembolization using iodized oil through the cystic artery.

  17. Ventriculoperitoneal shunt-related infections caused by Staphylococcus epidermidis: pathogenesis and implications for treatment.

    LENUS (Irish Health Repository)

    Stevens, Niall T

    2012-12-01

    The insertion of medical devices, such as intraventricular shunts, is often complicated by infection leading to ventriculitis. Frequently, such infections result from colonisation and subsequent biofilm formation on the surfaces of the shunts by Staphylococcus epidermidis. The pathogenesis of neurosurgical shunt-related infection is complex with interactions between the pathogen, the device and the unique local immunological environment of the central nervous system (CNS). An ability to form biofilm, the main virulence determinant of Staphylococcus epidermidis, facilitates protection of the organism from the host defences while still initiating an immunological response. The presence of the blood brain barrier (BBB) and the biofilm itself also complicates treatment, which presents many challenges when managing shunt infections. A greater understanding of the interplay between S. epidermidis and the CNS could potentially improve the diagnosis, treatment and management of such infections. This review describes the pathogenesis, treatment and implications of S. epidermidis ventriculoperitoneal shunt-related infections, concentrating on recent research and the implications for treatment.

  18. Unusual origin of the artery of Adamkiewicz from the fourth lumbar artery

    International Nuclear Information System (INIS)

    The main arterial supply of the dorso-lumbar spinal cord is usually derived from a single anterior radiculo-medullary artery called the artery of Adamkiewicz and referred to as having a middle or low location. In some cases, the artery origin is higher, and a vessel which arises in the lower part of the region supplements the supply of the anterior spinal artery. In the literature, those arteries have been described as arising from L3 upwards, and have never been previously described angiographically, to our knowledge, below this level, although Suh and Alexander and Gililan have mentioned this eventuality. Of the 4,000 spinal cord angiographies performed in our institution, we report three cases in which the fourth lumbar artery flows into the anterior spinal artery of the conus medullaris. This anatomical variant may explain the sometimes devastating post-operative neurological complications from a spinal cord infarction on surgery of the lumbar spine or the abdominal aorta below L3.

  20. Transcatheter Splenic Artery Occlusion for Treatment of Splenic Artery Steal Syndrome After Orthotopic Liver Transplantation

    International Nuclear Information System (INIS)

    Purpose: To review some aspects of the problem of splenic artery steal syndrome as cause of ischemia in transplanted livers and treatment by selective splenic artery occlusion. Materials and Methods: Eleven liver transplant patients from a group of 350 patients, nine men and two women,ranging in age from 40 years to 61 years (mean 52 years), presented with biochemical evidences of liver ischemia and failure, ranging from one to 60 days following orthotopic liver transplantation. Diagnosis of splenic artery steal syndrome was suspected by elevated enzymes, Doppler ultrasound and confirmed by celiac angiogram. Patients with confirmed hepatic artery thrombosis before angiography were excluded from the study. Embolization with Gianturco coils was performed. Results: All patients were treated by splenic artery embolization with Gianturco coils. The 11 patients improved clinically within 24 hours of the procedure with significant change in the biochemical and clinical parameters. Followup ranged from one month to two years. One of the 11 patient initially improved, but developed hepatic artery thrombosis within 24 hours of the embolic treatment,requiring surgical repair. Conclusion: Splenicartery steal syndrome following liver transplantation surgery can be diagnosed by celiac angiography, and effectively treated by splenic artery embolization with coils. Embolization is one of the treatments available, it is minimally invasive, and leads to immediate clinical improvement. Hepatic artery thrombosis is a possible complication of the procedure

  1. Causes of arterial bleeding after living donor liver transplantation and the results of transcatheter arterial embolization

    International Nuclear Information System (INIS)

    To analyze the causes of arterial bleeding after living donor liver transplantation (LDLT) and to evaluate the efficacy of transcatheter arterial embolization (TAE). Forty-two sessions of conventional arteriography were performed in 32 of the 195 patients who underwent LDLT during the past 2 years. This was done in search of bleeding foci of arterial origin. TAE was performed with microcoils or gelatin sponge particles. The causes of arterial bleeding, the technical and clinical success rates of TAE and the complications were retrospectively evaluated. Forty-two bleeding foci of arterial origin were identified on 30 sessions of arteriography in 21 patients. The most common cause of bleeding was percutaneous procedures in 40% of the patients (17 of the 42 bleeding foci) followed by surgical procedures in 36% (15/42). The overall technical and clinical success rates of TAE were 21 (70%) and 20 (67%) of the 30 sessions, respectively. The overall technical success rate of TAE for the treatment of bleeding from the hepatic resection margin, hepatic artery anastomotic site and hepaticojejunostomy was only 18% (2/11), whereas for the treatment of bleeding in the other locations the technical and clinical success rates of TAE were 100% and 95%, respectively. No procedure-related major complications occurred. In the case of arterial bleeding after LDLT, percutaneous procedure-related hemorrhages were as common as surgery-related hemorrhages. There were technical difficulties in using TAE for the treatment of hepatic arterial bleeding. However, in the other locations, TAE seems to be safe and effective for the control of arterial bleeding in LDLT recipients

  2. Retrograde catheterization via politeal artery for the treatment of ipsilateral superficial femoral artery occlusive disease: its clinical application

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical effect and application of retrograde catheterization via politeal artery in treating ipsilateral superficial femoral artery occlusive diseases. Methods: During the period from Jan. 2008 to June 2011, 15 patients with superficial femoral artery occlusive diseases were collected. A total of 17 narrowed or obstructed superficial femoral arteries were detected, including right (n=10) and left (n=7) femoral arteries. The length of the diseased artery ranged from 9 to 18 cm, with a mean of (12.5±6.8) cm. Percutaneous angioplasty (PTA) through ipsilateral retrograde catheterization via politeal artery together with stent implantation was performed to reopen the narrowed or obstructed superficial femoral arteries. After the procedure all patients were followed up for 3-24 months. The clinical results were analyzed. Results: The therapeutic success rate was 100% (17/17). No serious complications occurred. After the treatment, the ischemic symptoms were markedly improved or even disappeared. In 89.47% of patients (17/19) the superficial femoral arteries remained patent during the follow-up period. The preoperative ankle brachial index (ABI) was 0.15-0.48 (mean 0.28), while the postoperative ABI was 0.69-1.05 (mean 0.88). The difference in ABI between pre-operation and post-operation was statistically significant (P<0.05). Conclusion: For the treatment of superficial femoral arterial occlusive diseases, PTA through ipsilateral retrograde catheterization via politeal artery together with stent implantation is a safe effective therapy.

  3. Variation of hepatic artery on arteriogram and its clinical significance in interventional therapy for hepatic cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the variations of hepatic artery and its extrahepatic arteries on hepatic arteriogram and to provide benefit for transhepatic arterical chemoemblization. Methods: The hepatic arteriograms of 200 cases with unresectable hepatic malignant tumor before interventional therapy were analysed. Two interventional radiologists in common reviewed the incidences of various types according to Michels' classification, the absence of proper hepatic artery, and the variations of extrahepatic arteries originating from hepatic artery. Results: The most common hepatic artery variation was Michels type III(n=17,8.5%), followed by type II(n=10,5.0%) and V(n=9,4.5%). Proper hepatic absence was found in 25 cases and appeared as 5 subtypes. 5 kinds of extrahepatic arteries were found. The most common extrahepatic artery was the right gastric artery (n=156,78.0%), followed by cystic artery (n=126,63.0%), accessory left gastric artery (n=19,9.5%), the hepatic falciform artery (n=5,2.5%), and accessory left inferior phrenic artery (n=4,2.0%). Conclusion: There are some other variations of hepatic artery beside Michels' classification,and there are many variations of extrahepatic arteries originating from hepatic artery, it is important to assure interventional therapy effect for hepatic cancer and prevent complication.

    Dengue infection is highly endemic in many tropical countries including Malaysia. However, neurological complications arising from dengue infection is not common; Gullain-Barre syndrome (GBS) is one of these infrequent complications. In this paper, we have reported a case in which a 39-year-old woman presented with a neurological complication of dengue infection without typical symptoms and signs of dengue fever. She had a history of acute gastroenteritis (AGE) followed by an upper respiratory tract infection (URTI) weeks prior to her presentation rendering GBS secondary to the post viral URTI and AGE as the most likely diagnosis. Presence of thrombocytopenia was the only clue for dengue in this case. PMID:27099661

    2010-11-01

    Modern cataract surgery is safe in more than 95 per cent of patients. In the small number of cases where a serious complication occurs, the most common is an intra-operative posterior capsular rupture. This can lead to vitreous loss or a dropped nucleus and can increase the risk of post-operative cystoid macular oedema or retinal detachment. Post-operatively, posterior capsular opacification is the most common complication and can be readily treated with a YAG capsulotomy. The most devastating complication is endophthalmitis, the rate of which is now significantly decreased through the use of intracameral antibiotics. As a clinician, the most important step is to assess the patient pre-operatively to predict higher risk individuals and to counsel them appropriately. In these patients, various pre- or intra-operative management steps can be taken in addition to routine phacoemulsification to optimise their visual outcome. PMID:20735786

    Silicone breast implants have been used for augmentation mammoplasty for cosmetic purposes as well as for breast reconstruction following mastectomy for more than three decades. Though the use of the silicone gel filled variety has been banned in the USA except for special cases, they continue to be available elsewhere in the world including the UK. Despite the immense benefit they provide, their usage is associated with some complications. Most of these are related to the surgery and can be reduced by good surgical management. The major complications associated with their use is adverse capsular contracture, an outcome which can be very frustrating to manage. This article reviews the commonly reported complications and suggested management alternatives. PMID:9613406

    Full Text Available Abstract Background and objective: Staphylococcus aureus is one of the main causes of hospital infections. Staphylococcus saprophyticus is a common agent of urinary tract infections. Hospital acquired infection as an old challenge has high importance in hospital infection control and Staphylococcus spp. play main role among routine pathogens. this study designed to investigate the of Staphylococcus aureus and Staphylococcus saprophyticus among ICU, Men and Children wards. Materials and methods: Samples collected randomly from ICU, Men and Children wards. Through 203 sampling of wall, floor, bed, pillow and blanket, 75 Staphylococcus spp. isolated. Species recognizes base on culture on Mannitol salt agar and Novobiocin susceptibility determination. Result: Among 75 positive samples, 62 (82.7%, and 13 isolates were Staphylococcus saprophyticus, Staphylococcus aureus, respectively. 51% of bacteria isolated from ICU, 29% from children ward and 20% from men surgery ward. Staphylococcus saprophyticus comprised 87%, 82% and 73% of isolates pertaining to ICU, pediatric and men surgery wards, in a row. Conclusion: Our funding indicate there is an inappropriate instrument to deal with infection in hospital specially ICU. Regards to this issue that Staphylococcus spp. as a main pathogen which has potency to form biofilm and show high resistance to extended broad antibiotics therefore it is suggested to prepare proper guideline to cope with bacteria dissemination and resistance emergence in hospital.

    To evaluate the clinical efficacy and safety of a transcatheter arterial embolization (TAE) with N-butyl cyanoacrylate (NBCA) for the treatment of arterial esophageal bleeding. Between August 2000 and April 2008, five patients diagnosed with arterial esophageal bleeding by conventional angiography, CT angiography or endoscopy, underwent a TAE with NBCA. We mixed NBCA with iodized oil at ratios of 1:1 to 1:4 to supply radiopacity and achieve a proper polymerization time. After embolization, we evaluated the angiographic and clinical success, recurrent bleeding, and procedure-related complications. The bleeding esophageal artery directly originated from the aorta in four patients and from the left inferior phrenic artery in one patient. Although four patients had an underlying coagulopathy at the time of the TAE, angiographic and clinical success was achieved in all five patients. In addition, no procedurerelated complications such as esophageal infarction were observed during this study. NBCA can be an effective and feasible embolic agent in patients with active arterial esophageal bleeding, even with pre-existing coagulopathy.

    2016-02-01

    In the past decades three gaseous signaling molecules-so-called gasotransmitters-have been identified: nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S). These gasotransmitters are endogenously produced by different enzymes in various cell types and play an important role in physiology and disease. Despite their specific functions, all gasotransmitters share the capacity to reduce oxidative stress, induce angiogenesis, and promote vasorelaxation. In patients with diabetes, a lower bioavailability of the different gasotransmitters is observed when compared with healthy individuals. As yet, it is unknown whether this reduction precedes or results from diabetes. The increased risk for vascular disease in patients with diabetes, in combination with the extensive clinical, financial, and societal burden, calls for action to either prevent or improve the treatment of vascular complications. In this Perspective, we present a concise overview of the current data on the bioavailability of gasotransmitters in diabetes and their potential role in the development and progression of diabetes-associated microvascular (retinopathy, neuropathy, and nephropathy) and macrovascular (cerebrovascular, coronary artery, and peripheral arterial diseases) complications. Gasotransmitters appear to have both inhibitory and stimulatory effects in the course of vascular disease development. This Perspective concludes with a discussion on gasotransmitter-based interventions as a therapeutic option. PMID:26798119

  17. Moya Moya disease complicated by aneurism formation (with 22 cases report)

    International Nuclear Information System (INIS)

    Objective: To find out the occurrence and clinical significance of Moya Moya disease complicated by aneurism formation. Methods: A group of 258 cases of Moya Moya disease within past 12 years in the daily work were reviewed. 22 cases of them were complicated with aneurism formation manifested clinically by acute stroke in 12 cases, slow onset of the disease in 10 cases, and all the cases were confirmed via cerebral angiography. Results: Among the complicated aneurism, 18 were peripheral artery type (81.8%), in which 6 patients originated from perforating arteries, 7 from lenticulostriate arteries, 4 from posterior choroidal arteries; the other 4 cases were large artery type (18.19%). Conclusions: Moya Moya disease complicated with aneurism formation might result in intracranial haemorrhage. CT was used to locate the haematoma while DSA was used to verify the diagnosis. For large artery type aneurism, it can be treated with intra-vascular embolization, while peripheral artery type aneurism, yet no appropriate method is now available and still under further study

    2011-11-01

    Full Text Available Following the death of a loved one, a small group of grievers develop an abnormal grieving style, termed complicated or prolonged grief. In the effort to establish complicated grief as a disorder in DSM and ICD, several attempts have been made over the past two decades to establish symptom criteria for this form of grieving. Complicated grief is different from depression and PTSD yet often comorbid with other psychological disorders. Meta-analyses of grief interventions show small to medium effect sizes, with only few studies yielding large effect sizes. In this article, an integrative cognitive behavioral treatment manual for complicated grief disorder (CG-CBT of 25 individual sessions is described. Three treatment phases, each entailing several treatment strategies, allow patients to stabilize, explore, and confront the most painful aspects of the loss, and finally to integrate and transform their grief. Core aspects are cognitive restructuring and confrontation. Special attention is given to practical exercises. This article includes the case report of a woman whose daughter committed suicide.

    After the report of first case of methicillin-resistant Staphylococcus aureus (MRSA) in 1961, MRSA become a major problem worldwide. Over the last decade MRSA strains have emerged as serious pathogens in nosocomial and community settings. Glycopeptides (vancomycin and teicoplanin) are still the current mainstay of therapy for infections caused by MRSA. In the last decade dramatic changes have occurred in the epidemiology of MRSA infections. The isolates with reduced susceptibility and in vitro resistance to vancomycin have emerged. Recently, therapeutic alternatives such as quinupristin/dalfopristin, linezolid, tigecycline and daptomycin have been introduced into clinical practice for treating MRSA infections. Nevertheless, these drugs are only approved for certain indication and resistance has already been reported. In this review, the new information on novel drugs for treating MRSA infections and the resistance mechanisms of these drugs were discussed. PMID:21935792

    Full Text Available Staphylococcus aureus is an important pathogen of humans and livestock. It causes a diverse array of diseases, ranging from relatively harmless localized skin infections to life-threatening systemic conditions. Among multiple virulence factors, staphylococci secrete several exotoxins directly associated with particular disease symptoms. These include toxic shock syndrome toxin 1 (TSST-1, enterotoxins, and exfoliative toxins (ETs. The latter are particularly interesting as the sole agents responsible for staphylococcal scalded skin syndrome (SSSS, a disease predominantly affecting infants and characterized by the loss of superficial skin layers, dehydration, and secondary infections. The molecular basis of the clinical symptoms of SSSS is well understood. ETs are serine proteases with high substrate specificity, which selectively recognize and hydrolyze desmosomal proteins in the skin. The fascinating road leading to the discovery of ETs as the agents responsible for SSSS and the characterization of the molecular mechanism of their action, including recent advances in the field, are reviewed in this article.

    PurposeTo evaluate the usefulness of an approach through the radial artery distal to the arteriovenous anastomosis for salvaging nonmaturing radiocephalic arteriovenous fistulas.MethodsProcedures that fulfilled the following criteria were retrospectively reviewed: (1) autogenous radiocephalic fistulas, (2) fistulas less than 3 months old, (3) distal radial artery approach for salvage. From 2005 to 2011, a total of 51 patients fulfilling the above criteria were enrolled. Outcome variables were obtained from angiographic, clinical and hemodialysis records, including the success, complication, and primary and secondary patency rates.ResultsThe overall anatomical and clinical success rates for the distal radial artery approach were 96 and 94 %, respectively. The average procedure time was 36 {+-} 19 min. Six patients (12 %) experienced minor complications as a result of extravasations. No arterial complication or puncture site complication was noted. The postinterventional 6-month primary patency rate was 51 %, and the 6-month secondary patency rate was 90 %. When the patients were divided into a stenosed group (20 patients) and an occluded group (31 patients), there were no differences in the success rate, complication rate, or primary and secondary patency rates.ConclusionAn approach through the radial artery distal to the arteriovenous anastomosis is an effective and safe alternative for the salvage of nonmaturing radiocephalic arteriovenous fistulas, even for occluded fistulas.

  5. Post-traumatic intraarterial thrombolytic treatment for acute occlusion of the extremities artery

    International Nuclear Information System (INIS)

    Objective: To explore the clinical value of intraarterial thrombolytic therapy for acute arterial occlusion of the extremities artery after trauma. Methods: Six cases with acute arterial occlusion of the extremities after trauma underwent intraarterial thrombolytic therapy and the efficiency was analysed. Results: Digital Subtraction Angiograph (DSA)clearly displayed the location, extent and dimensions of the occlusive extremity arteries. All the occlusive arteries were recanalized with successful rate of 100%. 4 cases appeared to have ischemia-reperfusion injury after treatment, outcoming with recovery in one case by musculoaponeuratic splitting, and 3 cases through medication; and simultaneously the pulse of the occlusive arteries returned to normal and the local pains reduced or disapeared afterwards; without serious complications of necrosis, hemorrhage etc. Conclusions: The intraarterial thrombolytic treatment of acute arterial occlusion of the extremities after trauma is safe, effective, minimal invasive and less complication; providing the preparation for further stent placement.

    The authors report the case of a 67 year old man with a previous history of aortobifemoral arterial graft who had unstable angina after carotid endarterectomy. Coronary angiography by the right brachial artery was complicated by a cerebrovascular accident with a reactive coma, convulsions and respiratory problems. Selective angiography of the right vertebral artery showed an image of occlusive thrombosis of the basilar artery. In view of the clinical state and angiographic appearances, the authors decided on immediate intra-arterial thrombolysis with Urokinase which dissolved the clot and reestablished flow in the basilar artery, the cerebellar and posterior cerebral arteries. The outcome was favourable with immediate and good recovery of consciousness and hospital discharge on the sixth day without neurological or radiological sequellae. Cerebrovascular accident is a rare and potentially serious complication of left heart catheterisation which requires immediate cerebral angiography to determine the mechanism and propose an appropriate therapeutic approach.

  7. Endovascular stenting for vertebrobasilar artery stenosis

    International Nuclear Information System (INIS)

    Objective: To summarize the experiences in endovascular stenting for vertebrobasilar artery stenosis, and to discuss its indications, technique, and perioperative management. Methods: Twenty cases presented with recurrent transient ischemic attack or with the history of infarction of posterior circulation territory. Thirteen cases complained of dizziness or headache. The locations of the stenoses were originated at vertebral artery in 13 cases, extracranial segment of vertebral artery in 3 cases, intracranial segment of vertebral artery in 5 cases, and basilar artery in 12 cases. All stenoses were more than 70% in diameter, with 2-12 mm in length. Balloon expended stents (BX, AVES670, EXPRESS, BIODIVESO) were introduced across the stenosis with the support of guide wire. Stents were deployed by inflation of the balloon slowly. Results: There were no procedural and periprocedural complications, and angiographic results showed that the stenoses returned to normal size in 29 cases, while reduced by more than 80% in 4 cases. The patients were asymptomatic and neurologically intact at the clinical follow-up for 3-10 months. Ten cases were followed by angiography, and there was no restenosis. Conclusion: Endovascular stenting for vertebrobasilar artery stenosis is effective and safe. But long-term results need further investigation

    Full Text Available In patients with type 2 diabetes mellitus it might be helpful to use, for risk stratification, non-invasive techniques as markers of early atherosclerosis. Arterial stiffness shows the functional vascular properties and can be estimated by pulse wave velocity (PWV and augmentation index (AIX. Typical for type 2 diabetes is premature arterial stiffening which appears before the onset of clinically micro or macrovascular disease and is increased in the presence of microvascular complications. Further studies are needed to determine whether therapeutic interventions for reducing vascular stiffness may decrease the cardiovascular mortality in patients with type 2 diabetes.

    Uncommon microorganisms are increasingly being recognized as causative agents of paediatric infectious endocarditis (IE). We report a 4-year old girl with congenital heart disease, who suffered from 2 IE episodes secondary to Aggregatibacter aphrophilus (formerly Haemophilus aphrophilus) and Staphylococcus lugdunensis, both rarely reported pathogens in this age group. The patient was initially successfully treated with prolonged intravenous antibiotic courses, however removal of the Contegra valved conduit during the second episode was required due to recurrence of fever and development of pulmonary embolism despite completion of antibiotic therapy. A. aphrohilus is a member of the fastidious gram negative microorganisms of the HACEK group (Haemophilus spp., Aggregatibacter spp, Cardiobaterium hominis, Eikenella corrodens and Kingella kingae), that colonize the oropharynx and are a recognised cause of IE. Prognosis of children with IE due to HACEK group members varies, half of them suffering from complications and mortality rates of 10-12.5%. Although S. lugdunensis belongs to coagulase negative staphylococci (CONS), it behaves more like S. aureus species rather than CONS. This microorganism is a well-described cause of endocarditis in adult patients, associated with high requirements of surgical procedures and mortality (42-78%). In conclusion, paediatric IE can be caused by uncommon microorganisms associated with severe complications and potential fatality. The isolation of S. lugdunensis or A. aphrophilus in febrile patients should be considered clinically relevant and cardiac involvement must be ruled out. Those patients with proved IE will require prolonged intravenous antibiotic courses and in complicated cases surgical intervention. PMID:25751682

    Full Text Available Aim: To assess the neurological complications of chickenpox with prognosis. Background: The neurological complications occur in 0.03% of persons who get chickenpox. There is no universal vaccination against chicken pox in India. Most patients prefer alternate modalities of treatment. Hence these complications of chickenpox are likely to continue to occur. Study Design: A prospective study was conducted for 2 years (from March 2002 on the admitted cases with neurological complications after chickenpox (with rash or scar. Patients were investigated with CT/MRI, CSF study, EEG and nerve conduction studies and hematological workup. They were followed-up for 1 year and outcome assessed using modified Rankin scale. Results: The latency for the neurological complications was 4-32 days (mean: 16.32 days. There were 18 cases: 10 adults (64% and 8 children (36%. Cerebellar ataxia (normal CT/MRI was observed in 7 cases (32% (mean age: 6.85 years. One patient (6 years had acute right hemiparesis in the fifth week due to left capsular infarct. All these cases spontaneously recovered by 4 weeks. The age range of the adult patients was 13-47 years (mean: 27 years. The manifestations included cerebellar and pyramidal signs (n-4 with features of demyelination in MRI who recovered spontaneously or with methylprednisolone by 8 weeks.

    Summary A 32-year-old woman hospitalized for subarachnoid hemorrhage showed rare arterial variation on the right side with anomalous origins of the vertebral artery, aberrant subclavian artery and persistent trigeminal artery. Angiography showed the right vertebral artery to originate from the right common carotid artery, the right subclavian artery to arise separately from the descending aorta, and persistent trigeminal artery on the right side. The possible embryonic mechanism of this previously unreported variant combination is discussed. PMID:22005696

    We discuss two cases of Gaucher's disease of the adult with neurological complications. First of the patients came to Hospital due to sudden pain in dorso-lumbar region and motor weakness of lower extremities. In the neurological exploration there were no concluding objective deficit signs except an unstable deambulation. After several hours of rest, symptoms disappeared progressively. In the radiology of the raquis a crushed in the last three dorsal vertebral was seen; this finding together with the clinic the patient showed, suggested a mild and transitory medullar compression. Second patient suffered an intraparenchymatous brain hemorrhage on the course of a platelet depletion and with other mild coagulation disorders. This type of complication have never been described in Gaucher's disease. PMID:1470721

  1. Endovascular parent artery occlusion in large-giant or fusiform distal posterior cerebral artery aneurysms

    International Nuclear Information System (INIS)

    Posterior cerebral artery aneurysms are amenable to deconstructive surgical treatment because of the rich collateral supply of the distal posterior cerebral artery. This report retrospectively analyses the outcome of endovascular parent artery occlusion for large or fusiform distal posterior cerebral artery aneurysms. Medical records and cerebral angiograms from two endovascular centres were analysed retrospectively. Eight patients with large or fusiform distal posterior cerebral artery (PCA) aneurysms were treated by endovascular occlusion of the segment of the PCA at the site of the aneurysm. Three of those were treated urgently after acute subarachnoid haemorrhage, the remainder had elective treatment. The clinical and angiographic outcomes in seven patients were assessed at 6 to 12 months. A single case of occipital infarction resulting in permanent homonymous hemianopia was the only permanent complication. Of the remaining patients, six made excellent recoveries and one was lost to follow-up. No recurrence or re-bleeding was noted. Endovascular parent artery occlusion may be an alternative to surgical parent artery occlusion in distal PCA aneurysms which are not convenient for selective endovascular treatment or surgical clipping.

    Chronic hyperglycemia and duration of diabetes are the major risk factors associated with development of micro- and macrovascular complications of diabetes. Although it is believed that hyperglycemia induces damage to the particular cell subtypes, e.g., mesangial cells in the renal glomerulus, capillary endothelial cells in the retina, and neurons and Schwann cells in peripheral nerves, the exact mechanisms underlying these damaging defects are not yet well understood. Clustering of micro- and macrovascular complications in families of patients with diabetes suggests a strong genetic susceptibility. However, until now only a handful number of genetic variants were reported to be associated with either nephropathy (ACE, ELMO1, FRMD3, and AKR1B1) or retinopathy (VEGF, AKR1B1, and EPO), and only a few studies were carried out for genetic susceptibility to cardiovascular diseases (ADIPOQ, GLUL) in patients with diabetes. It is, therefore, obvious that the accumulation of more data from larger studies and better phenotypically characterized cohorts is needed to facilitate genetic discoveries and unravel novel insights into the pathogenesis of diabetic complications.

  9. Thrombophilia and Pregnancy Complications

    Louise E. Simcox

    2015-11-01

    Full Text Available There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction. Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

    The authors describe a case of keratomycosis that appeared after the exeresis of a pterygium. A 48-year-old patient had been referred with a red right eye associated with an abscess of the cornea along the ablation zone of the pterygium. The surgery had been performed a month beforehand. The abscess was 6 mm high and 4 mm wide. The authors instigated a treatment that included amphotericin B (0.25%) after noticing a clinical aspect evoking a fungal keratitis and finding several septate filaments on direct examination. On day 10, a Fusarium dimerum was isolated on Sabouraud agar. After 15 days of treatment, the result was favorable and the size of the ulceration as well as the size of the abscess had progressively decreased. The antifungal treatment was definitively stopped at 14 weeks. Infectious-related complications of the pterygium surgery are rare and are essentially caused by bacterial agents. Secondary infections by fungus are rare. There have been two previous cases reported: one that appeared 15 years after radiotherapy and another that appeared at 3 weeks post surgery, consecutive to the use of mitomycin C. To the authors' knowledge, this is the first case of a keratomycosis due to F. dimerum reported that complicated the exeresis of a pterygium without the use of an adjuvant antihealing treatment. Pterygium surgery is a common procedure; nevertheless, ophthalmologists need to be aware of the existence of potential infectious complications. PMID:22034566

    Cardiovascular disease is one of the leading cause of mortality in the US and especially, coronary artery disease increases with an aging population and increasing obesity. Currently, bypass surgery using autologous vessels, allografts, and synthetic grafts are known as a commonly used for arterial substitutes. However, these grafts have limited applications when an inner diameter of arteries is less than 6 mm due to low availability, thrombotic complications, compliance mismatch, and late intimal hyperplasia. To overcome these limitations, tissue engineering has been successfully applied as a promising alternative to develop small-diameter arterial constructs that are nonthrombogenic, robust, and compliant. Several previous studies have developed small-diameter arterial constructs with tri-lamellar structure, excellent mechanical properties and burst pressure comparable to native arteries. While high tensile strength and burst pressure by increasing collagen production from a rigid material or cell sheet scaffold, these constructs still had low elastin production and compliance, which is a major problem to cause graft failure after implantation. Considering these issues, we hypothesized that an elastometric biomaterial combined with mechanical conditioning would provide elasticity and conduct mechanical signals more efficiently to vascular cells, which increase extracellular matrix production and support cellular orientation. The objective of this report is to introduce a fabrication technique of porous tubular scaffolds and a dynamic mechanical conditioning for applying them to arterial tissue engineering. We used a biodegradable elastomer, poly (glycerol sebacate) (PGS) for fabricating porous tubular scaffolds from the salt fusion method. Adult primary baboon smooth muscle cells (SMCs) were seeded on the lumen of scaffolds, which cultured in our designed pulsatile flow bioreactor for 3 weeks. PGS scaffolds had consistent thickness and randomly distributed macro

    Full Text Available The extracranial internal carotid artery aneurysm (EICAA is an uncommon arterial lesion. Patients typically present with neurologic symptoms resulting from impaired cerebral perfusion and compression symptoms of cranial nerves. Often EICAA presents as a pulsatile neck mass, which is otherwise asymptomatic. We present a case of an 84-year-old female, who was initially referred to the Emergency Department for Otolaryngology with suspected peritonsillar abscess. The patient had a history of recent upper airway infection and cardiovascular comorbidities, including hypertension and ischaemic stroke complicated by extensive neurologic deficits. Physical examination revealed a compact, nonpulsatile mass in the lateral parapharyngeal space and local erythema of the mucosa. Duplex Doppler Ultrasonography and Computed Tomography revealed an atherosclerotic aneurysm of the right internal carotid artery, measuring 63×55×88 mm, stretching from the skull base to the angle of the mandible.

  14. Pancreatic transplantation: Radiologic evaluation of vascular complications

    International Nuclear Information System (INIS)

    Transplantation of the pancreas is an increasingly common therapeutic option for preventing or delaying complications of type I diabetes mellitus. The authors studied the relative roles of various radiologic examinations in diagnosing vascular complications in these grafts including arterial and venous thrombosis, stenosis, and anastomotic leak (the most common vascular factors that necessitate pancreatectomy of the transplant), as defined with pathologic or arteriographic data. The results of 78 scintigraphic flow studies, 40 abdominal and pelvic computed tomographic (CT) scans, 27 sonograms, and eight color Doppler studies were evaluated in 52 patients who received a total of 27 cadaveric and 26 living-donor grafts over a 12-year period. These results were correlated with the data from 45 gross and microscopic pathologic studies and 37 arteriograms to determine their relative value in enabling detection of graft thrombosis and other vascular complications. Scintigraphy, CT, sonography, and color Doppler were all sensitive in detection of generalized graft abnormalities but lacked specificity in defining the underlying etiologic factors

    Full Text Available Introduction: The anatomical variants of the hepatic artery may have important implications for pancreatic cancer surgery. The aim of our study is to compare the outcome following a pancreatoduodenectomy (PD in patients with or without a variant hepatic artery arising from superior mesenteric artery. Material and methods: We reviewed 151 patients with periampullary tumoral pathology. All patients underwent oncological PD between January 2005 and February 2012. Our series was divided into two groups: Group A: Patients with a hepatic artery arising from superior mesenteric artery; and Group B: Patients without a hepatic artery arising from superior mesenteric artery. We expressed the results as mean ± standard deviation for continuous variables and percentages for qualitative variables. Statistical tests were considered significant if p < 0.05. Results: We identified 11 patients with a hepatic artery arising from superior mesenteric artery (7.3%. The most frequent variant was an aberrant right hepatic artery (n = 7, following by the accessory right hepatic artery (n = 2 and the common hepatic artery trunk arising from the superior mesenteric artery (n = 2. In 73% of cases the diagnosis of the variant was intraoperative. R0 resection was performed in all patients with a hepatic artery arising from superior mesenteric artery. There were no significant differences in the tumor resection margins and the incidence of postoperative complications. Conclusion: Oncological PD is feasible by the presence of a hepatic artery arising from superior mesenteric artery. The complexity of having it does not seem to influence in tumor resection margins, complications and survival.

    Septic arthritis following anterior cruciate ligament reconstruction is an uncommon but a serious complication resulting in six times greater hospital costs than that of uncomplicated ACL surgery and an inferior postoperative activity level. Promptly initiating a specific antibiotic therapy is the most critical treatment, followed by open or arthroscopic joint decompression, debridement and lavage. Staphylococcus lugdunensis is a coagulase-negative staphylococcus predominantly infecting the skin and soft tissue. The few reported cases of bone and joint infections by S. lugdunensis indicate that the clinical manifestations were severe, the diagnosis elusive, and the treatment difficult. If the microbiology laboratory does not use the tube coagulase (long) test to confirm the slide coagulase test result, the organism might be misidentified as Staphylococcus aureus. S. lugdunensis is more virulent than other coagulase-negative staphylococcus; in many clinical situations it behaves like S. aureus, further increasing the confusion and worsening the expected outcome. S. lugdunensis is known to cause infective endocarditis with a worse outcome, septicemia, deep tissue infection, vascular and joint prosthesis infection, osteomyelitis, discitis, breast abscess, urine tract infections, toxic shock and osteitis pubis. We present the first case report in the literature of septic arthritis with S. lugdunensis following arthroscopic ACL revision with bone-patellar-tendon-bone allograft. PMID:17684731

    Purpose. Avoidance of nontarget microsphere deposition via hepatoenteric anastomoses is essential to the safety of yttrium-90 radioembolization (RE). The hepatic hilar arterial network may remain partially patent after coil embolization of major arteries, resulting in persistent risk. We retrospectively reviewed cases where n-butyl cyanoacrylate (n-BCA) glue embolization was used to facilitate endovascular hepatic arterial skeletonization before RE. Methods. A total of 543 RE procedures performed between June 2004 and March 2012 were reviewed, and 10 were identified where n-BCA was used to embolize hepatoenteric anastomoses. Arterial anatomy, prior coil embolization, and technical details were recorded. Outcomes were reviewed to identify subsequent complications of n-BCA embolization or nontarget RE. Results. The rate of complete technical success was 80 % and partial success 20 %, with one nontarget embolization complication resulting in a minor change in treatment plan. No evidence of gastrointestinal or biliary ischemia or infarction was identified, and no microsphere-related gastroduodenal ulcerations or other evidence of nontarget RE were seen. Median volume of n-BCA used was <0.1 ml. Conclusion. n-BCA glue embolization is useful to eliminate hepatoenteric networks that may result in nontarget RE, especially in those that persist after coil embolization of major vessels such as the gastroduodenal and right gastric arteries.

    Objective: To investigate the angiographic manifestation of the proper esophageal artery (PEA), the high risk factors for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter arterial embolization (TAE) of the PEA using gelatin sponge (GS). Methods: Selective esophageal arteriography was performed in forty-three patients with hemoptysis, including 15 cases of pulmonary tuberculosis, 18 cases of bronchiectasis, 7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs was studied. The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS. Results: Thirty-nine PEAs were catheterized selectively in 37 patients (86.0%). Eighteen anomalous PEAs (46.2%) were catheterized selectively in 17 patients (45.9%). The anomalous PEAs showed tortuosity, dilatation, hyperplasia, shunting with pulmonary artery and anastomosis with the bronchial artery. All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect was achieved with TAE of the anomalous PEAs. Conclusions: It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis. Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis. (authors)

A 48-year-old patient had been referred with a red right eye associated with an abscess of the cornea along the ablation zone of the pterygium. The surgery had been performed a month beforehand. The abscess was 6 mm high and 4 mm wide. The authors instigated a treatment that included amphotericin B (0.25% after noticing a clinical aspect evoking a fungal keratitis and finding several septate filaments on direct examination. On day 10, a Fusarium dimerum was isolated on Sabouraud agar. After 15 days of treatment, the result was favorable and the size of the ulceration as well as the size of the abscess had progressively decreased. The antifungal treatment was definitively stopped at 14 weeks. Infectious-related complications of the pterygium surgery are rare and are essentially caused by bacterial agents. Secondary infections by fungus are rare. There have been two previous cases reported: one that appeared 15 years after radiotherapy and another that appeared at 3 weeks post surgery, consecutive to the use of mitomycin C. To the authors' knowledge, this is the first case of a keratomycosis due to F. dimerum reported that complicated the exeresis of a pterygium without the use of an adjuvant antihealing treatment. Pterygium surgery is a common procedure; nevertheless, ophthalmologists need to be aware of the existence of potential infectious complications. Keywords: keratitis, corneal abscess, Fusarium

    Pulmonary arteriovenous malformations (PAVMs) with feeding arteries of 3 mm or more have been shown to be associated with paradoxical embolization and serious neurologic complications. Therefore it is generally recommended to occlude feeding arteries of this size, while smaller feeding arteries....... Further, it is well-known that with time PAVMs and their feeding arteries may enlarge. Also, embolization of small feeding arteries will minimize the risk of paradoxical emboli and reduce the need for CT follow-up controls in these patients.

    Introduction Severe nephrotic syndrome is associated with increased morbidity and mortality. Renal artery embolization (RAE) has been used in a number of renal diseases such as renal tumors, arteriovenous fistulas etc. However, data regarding benefits of RAE in patients with symptomatic severe proteinuria is limited. We decided to evaluate role of RAE in the setting of severe symptomatic nephrotic syndrome. Methods Eight patients who had undergone transcatheter renal artery embolization with polyvinyl alcohol (PVA) were included. Clinico-demographic characteristics as well as baseline laboratory data including level of proteinuria, serum albumin, C-reactive protein and LDL cholesterol levels were recorded for each patient. After RAE, outpatient clinic control laboratory values were also assessed. Findings All patients except one underwent bilateral RAE (four simultaneous or three sequential). Two patients experienced postembolization syndrome characterized by flank pain, fever, and leukocytosis, which was self-limited and responded to analgesics in all patients. There was no technical complications associated with RAE procedure. All patients became anuric except one. Serum albumin levels increased and serum LDL-cholesterol levels decreased considerably in treated patients. Discussion Renal artery embolization with the purpose of amelioration in nephrotic syndrome complications was effective and free of major technical complications in our patients. PMID:26833695

    More than 4 decades after the creation of the Brooke and Parkland formulas, burn practitioners still argue about which formula is the best. So it is no surprise that there is no consensus about how to resuscitate a thermally injured patient with a significant comorbidity such as heart failure or cirrhosis or how to resuscitate a patient after an electrical or inhalation injury or a patient whose resuscitation is complicated by renal failure. All of these scenarios share a common theme in that the standard rule book does not apply. All will require highly individualized resuscitations. PMID:27600129

Whenever possible, the separate toxicity of chemotherapy, irradiation, and combination therapy is addressed. However, it is not always possible to quantitate specifically such reactions in the face of multiple drug therapy, which may enhance radiation injury or reactivate prior radiation injury. Prior detailed reviews have provided important sources of information concerning radiation injury for this more general discussion. The information provided will assist both the clinician and the radiologist in the recognition of early and late complications of therapy in pediatric oncology

    An 81-year-old man was treated with intravenous antibiotics for a soft tissue infection in a finger. Despite adequate antibiotic treatment, he developed signs of spinal cord injury caused by a cervical spinal epidural abscess. An emergency laminectomy was performed. The neurological impairment appeared to be irreversible, and the patient died. Spinal epidural abscess is a rare and serious complication ofa bacteraemia. It is often caused by an infection of the skin or soft tissue with Staphylococcus aureus. Given the risk of rapidly progressive and irreversible neurological damage, this complication must be treated as soon as possible. The treatment of choice is surgery. Conservative management with intravenous antibiotics is an option only under strict conditions. PMID:18624007

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

    Full Text Available Identification of the origin of the central retinal artery (CRA is imperative in tailoring angiographic studies to resolve a given clinical problem. A case with dual ophthalmic arteries (OAs, characterized by different origins and distinct branching patterns, is documented for training purposes. Pre-clinical diagnosis of a 9-year-old child who presented with a sharp wire in the left-side eyeball was primarily corneal laceration. For imaging, a selected six-vessel angiographic study with the transfemoral approach was performed. Embolization was not required and the wire could be successfully removed. Right-side OA anatomy was normal, while left-side dual OAs with external carotid artery (ECA and internal carotid artery (ICA origins were seen. The case presented with a left-side meningo-ophthalmic artery (M-OA anomaly via the ECA, marked by a middle meningeal artery (MMA (origin: Maxillary artery; course: Through foramen spinosum with normal branches (i.e. anterior and posterior branches, and an OA variant (course: Through superior orbital fissure with a distinct orbital branching pattern. A smaller OA (origin: ICA; course: Through optic foramen with a distinct ocular branching pattern presented with the central retinal artery (CRA. The presence of the dual OAs and the M-OA anomaly can be explained by disturbed evolutionary changes of the primitive OA and stapedial artery during development. The surgical interventionist must be aware of dual OAs and M-OA anomalies with branching pattern variations on retinal supply, because of dangerous extracranial-intracranial anastomotic connections. It is of clinical significance that the origin of the CRA from the ICA or ECA must be determined to avoid complications to the vision.

  7. Helical CT evaluation of internal carotid artery stenoses

    International Nuclear Information System (INIS)

    To determine the utility of helical CT angiography in the evaluation of carotid artery stenoses, helical CT images (reconstructed three-dimensional images, reconstructed multiplanar images, and two-dimensional axial images) obtained from 60 patients were compared with images obtained using conventional angiography. Based on conventional angiographic criteria, 22 arteries had no stenosis, 26 had mild stenosis. 69 had severe stenosis, and 3 were occluded. All carotid bifurcations were clearly identified on helical CT scanning and there were no complications. There were no motion artifacts due to the short examination time. In normal arteries, reconstructed three-dimensional images provided accurate anatomic depiction of the carotid bifurcation. Calcification was present at the stenotic lesion in 52 arteries. In 43 arteries in which the stenotic lesion was free of calcification, the degree of carotid stenosis determined using reconstructed three-dimensional images correlated with that determined using conventional angiography. In 19 of 52 arteries with calcification at the stenotic lesion, the calcification was focal and did not obscure the vessel lumen significantly when viewed from multiple angles. In the other 33 arteries, the calcification was dense and/or circumferential, making it difficult to evaluate the axial images allowed evaluation of the vessel lumen in the area of calcification, and the degree of stenosis was similar to that determined by conventional angiography. In 3 arteries, occlusion of the internal carotid artery was seen in reconstructed three-dimensional images and was confirmed by conventional angiography. (K.H.)

    2016-01-01

    In giant cell arteritis (GCA), involvement of the vertebral arteries is rare with reported rates of 3%–4% for ischemic events secondary to vertebral artery stenosis or occlusion for those patients with GCA. This case study describes a patient who initially presented with acute onset of vertigo but was also found to have transient, side-alternating upper limb neurological findings. While initial imaging showed no vascular abnormalities, it was not until GCA was eventually confirmed with a temporal artery biopsy that the initial scans were shown to have bilateral narrowing of the vertebral arteries. While rare, vertebral artery involvement is an important complication to consider in the setting of GCA due to the high rate of associated mortality, despite immunosuppressive therapy. PMID:27279753

  10. Embolization of a large, symptomatic splenic artery pseudoaneurysm

    International Nuclear Information System (INIS)

    Splenic artery aneurysm is the third most common abdominal aneurysm. Most often it is due to pancreatitis. There were only 19 cases of aneurysms larger than 5 cm in diameter described in the literature. Management of splenic artery aneurysms depends on the size and symptoms. Invasive treatment modalities involve open procedures and interventional radiology methods (endovascular). A 44-years-old male with chronic pancreatitis, in a gradually worsening general condition due to a large splenic artery aneurysm, was subjected to the procedure. Blood flow through the aneurysm was cut-off by implanting a covered stent between celiac trunk and common hepatic artery. Patient’s general condition rapidly improved, allowing discharge home in good state soon after the procedure. Percutaneous embolization appears to be the best method of treatment of large splenic artery aneurysms. Complications of such treatment are significantly less dangerous than those associated with surgery

    Background Recently, much attention has been paid to hepatic artery reconstruction in rat liver transplantation, which can prevent bile duct ischemia and preserve better liver structure. In this study, three methods of graft arterialization,including sleeve, cuff, and stent anastomosis, were conducted and the results were compared.Methods Orthotopic liver transplantation (OLT) with rearterialization was conducted in 90 rats, which were divided into sleeve, cuff, and stent groups (n=30 in each). Ninety-six rats received OLTs with standardized two-cuff technique without rearterialization as a control. The sleeve technique included an end-to-end anastomosis between the donor common hepatic artery and recipient proper hepatic artery, or between the donor celiac artery and recipient common hepatic artery.Cuff technique involved an anastomosis between the donor common hepatic artery and recipient common hepatic artery.In the stent technique, the recipient hepatic artery and donor hepatic artery were connected using an intraluminal polyethylene stent. The arterial anastomosis time and arterial patency rate in each group were recorded. The liver graft survival and bile duct complication rates were measured.Results The total surgical time of OLT with rearterialization was (118.3±12.9) minutes in the sleeve group, (106.2±11.6)minutes in the cuff, (93.8±10.2) minutes in the stent, and (88.2±9.6) minutes in the control. The corresponding anhepatic phase was (19.6±2.8), (19.2±2.2), (18.6±1.8), and (20.0±2.5) minutes respectively in the sleeve, cuff, stent, and control groups. One-week survival rate was 86.5% in the control, and 86.7% in the groups with rearterialization. No significant difference was detected in the survival rate between them (P>0.05). The incidence of biliary complications in non-rearterialized group (17.7%) was significantly higher than that in the rearterialized group (6.7%, P<0.05). No significant difference was found in the incidence of biliary

    International Nuclear Information System (INIS)

    Objective: To determine the etiology, clinical manifestation, management (medical and surgical) and complications of children with empyema thoracis in a tertiary care hospital from Karachi, Pakistan. Study Design: Descriptive, analytical study. Place and Duration of Study: Department of Surgery, The Aga Khan University Hospital, Karachi, from January 1996 to December 2010. Methodology: Medical records of admitted children aged > a month to 15 years with discharge diagnosis of empyema thoracis and data was collected on demographic features, clinical manifestation, management and complications. Children managed medically were compared with those managed surgically by using interquartile range and median comparison. Mann-Whitney U test was used to compare age in months, weight (kg) and length of stay in days and presenting complaint, duration of illness; chi-square test was used to compare thrombocytosis in between groups and p-value was calculated. Results: Among the 112 patients, 59 (53%) were younger than 5 years of age. Males (n=83, 74%) were predominant. Fifty (45%) children were admitted in winter. Thirty (27%) children found unvaccinated and one fourth (n=27; 24%) were severely malnourished. Fever, cough, and dyspnea were the major presenting symptoms. Sixty-six (59%) were on some antibiotics prior to admission. Staphylococcus aureus (n=13) and Streptococcus pneumoniae (n=5) were the commonest organism isolated from blood and pleural fluid cultures. Majority of the children required some surgical intervention (n=86). Surgically managed children were younger (p=0.01); had less weight (p=0.01) and prolonged fever (p=0.02); and stayed longer in hospital (p < 0.001) as compared to medically managed children. Requiring readmission (n=8), subcutaneous emphysema (n=5) and recollection of pus (n=5) were the major complications. Conclusion: Staphylococcus aureus was the major organism associated with paediatric empyema thoracis. Early identification and empiric

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical therapeutic effect of transcatheter arterial embolization (TAE) for treating massive haemorrhage in pelvic fracture (traffic accident 23, fall injury 5, hit trauma 4, crush injury 3). Methods: Thirty five patients with massive haemorrhage of pelvic fracture(traffic accident 23, fall injury 5, hit trauma 4, crush injury 3), also included 18 complicated injury cases. The inguinal region with free of or small hematoma was apt for femoral arterial puncture and followed by transcatheter bilateral iliac arterioangiography in order to confirm the site of haemorrhage. The gelfoam embolization was performed with superselective catheterization, otherwise the trunk of iliac artery would be embolized to slow down the blood flow and then coils with diameter from 5 to 8 mm were used for embolizing the trunk of iliac artery finally. The bilateral iliac arteries were embolized in the case of patients with bilateral or intermediate fracture. Results: Arterial spasm occurred in all patients with different severities and the patchy or linear extravasation of the contrast agent appeared in 29 patients through arteriography. All patients passed a successful embolization with a recovery of normal blood pressure (90-130)/(60-90)mmHg within 24 hours, without serious complications except one person had a minor skin necrosis at the distal part of big toe. Conclusions: The transcatheter arterial embolization is a simple, minimally invasive, safe and effective procedure, for treating the massive haemorrhage of pelvic fracture. (authors)

    'y-agonist on plasma concentrations of inflammatory cytokine in patients with diabetes mellitus complicated with coronary artery disease (CAD). Methods Eighty CAD patients were divided into four groups- rosiglitazone group (n=20), bezafibrate group (n=20), combination of rosiglitazone and bezafibrate group(n=20) and control group(n= 20). After treatment, patients were followed-up for 12 weeks. Plasma sample was collected from each patient before and after the treatment, respectively. Then plasma concentrations of C-reactive protein(CRP) and monocyte chemoatactic protein-1 (MCP-1) were measured by enzyme-linked immunosorbent assay. At the same time, the changes of fasting plasma glucose (FPC), fasting insulin, insulin resistance index (IRI), hemoglobin Ale (HbAlc), lipid and body mass index were also investigated. Results At the end of 12 weeks, patients in rosiglitazone group,bezafibrate group and combined rosiglitazone and bezafibrate group showed significantly reduction in plasma concentrations of CRP, MCP-1, FPG, insulin, IRI, HbAlc, triglycerides, total cholesterol, low-density lipoprotein cholesterol, and increasion in concentration of high-density lipoprotein cholesterol (P<0.05), especially in combined rosiglitazone and bezafibrate group. Concentrations of MCP-1 secreted by monocyte which was induced by lipopolysaccharide in rosiglitazone group,bezafibrate group and combined rosiglitazone and bezafibrate group were siginificantly higher after 12 weeks treatment than thoae before treatment (P<0.05), and the decrease was most obviously in combined rosiglitazone and bezafibrate group. Decline in plasma concentrations of CRP appear to be correlated with the decrease of insulin (r=0.048,P<0.01) and insulin resistance index (r =0.496, P<0.001), but there was no correlation with other factors. Conclusions Combination of rosiglilazone and bezafibrale can increase insulin sensitivity, improve glucose metabolism and reduce the concentrations of CRP, MCP-1 in patients with diabetes

  18. Prevention of cardiac complications in peripheral vascular surgery

    International Nuclear Information System (INIS)

    The prevalence of severe coronary artery disease in peripheral vascular patients exceeds 50 per cent. Complications of coronary artery disease are the most common causes of mortality following peripheral vascular operations. To reduce the incidence of cardiac complications, it is first necessary to identify patients at risk through screening tests. Screening methods in current use include risk factor analysis, exercise testing, routine coronary angiography, and dipyridamole thallium-201 scintigraphy. The risk factor approach has the advantage of being widely applicable since it makes use of historical, physical, and electrocardiographic findings that are already familiar to surgeons and anesthesiologists. It is also inexpensive. However, it may overlook the patient who has no symptoms of coronary artery disease, possibly as a result of the sedentary lifestyle imposed by complications of peripheral vascular disease. The electrocardiographically monitored stress test will identify the asymptomatic patient with occult coronary disease and is helpful in predicting operative risk. However, a meaningful test is dependent on the patient's ability to exercise--an activity that is frequently limited by claudication, amputation, or arthritis. Exercise testing also suffers from a lack of sensitivity and specificity when compared with coronary arteriography. Routine preoperative coronary angiography overcomes the exercise limitation of treadmill testing but is not widely applicable as a screening test for reasons of cost and inherent risk. Dipyridamole thallium-201 scanning, on the other hand, is safe and of relatively low cost and does not require exercise

    Johansen LK

    2013-08-01

    Full Text Available Louise Kruse Johansen, Henrik Elvang JensenDepartment of Veterinary Disease Biology, Faculty of Health and Medical Science, University of Copenhagen, Frederiksberg, DenmarkAbstract: Hematogenous osteomyelitis (HO, especially due to Staphylococcus aureus, is primarily reported in children and occurs when blood-borne bacteria settle in the metaphysis of a long bone and mediate an inflammatory response. The literature contains several reports on animal models aiming to simulate pediatric HO, in order to investigate the pathogenesis and for therapeutic use. In these models, osteomyelitis lesions develop subsequently to bacteremia, which can be induced by either intravenous or intra-arterial inoculation of bacteria. Intravenous inoculation is not optimal because of the ethical aspects of the extensive systemic reaction and the unpredictable identity of bones being infected. Also, intravenous inoculation often has to be combined with the induction of artificial bone necrosis in order to have macroscopic lesions. In contrast, models based on intra-arterial inoculation and subsequent development of local osteomyelitis, are the most accurate and predictable way to extrapolate to pediatric cases of HO. The most commonly used animal species for modeling of HO are rabbits, chickens, and mice, whereas, less frequently, dogs, rats, and pigs have been applied. The use of intra-arterial inoculation, without simultaneous artificial bone necrosis for the development of HO lesions has only been used in porcine models. Because of the similarity of human and porcine physiology, metabolic rate, and size, porcine models of HO are advantageous. Therefore, porcine models based on the intra-arterial induction of osteomyelitis are the most refined HO models.Keywords: hematogenous osteomyelitis, animal models, Staphylococcus aureus

    To evaluate the efficacy and safety of transcatheter arterial chemoembolization(TACE) after coil embolization of the gastroduodenal artery in hepatocellular carcinoma cases with multiple collateral arteries caused by proper hepatic artery injury. Between March 1997 and November 1998, a prospective trial of transcatheter arterial chemoembolization (TACE) was performed through collaterals from the gastroduodenal artery of 31 hepatocellular carcinoma patients with extensive proper hepatic artery injury due to repeated TACE. Among this number, 16 (group A) underwent TACE after coil embolization of the right gastric and gastroduodenal artery. The other 15 patients (group B) underwent TACE without coil embolization. The two groups had the same TNM stage and Clild-Pugh status. During the follow-up period, group A underwent additional TACE 3.3 times, and group B 2.8 times. The therapeutic effect of TACE was evaluated with computed tomography and by measuring alpha-fetoprotein levels. Complications were evaluated by means of gastrofibroscopy, laboratory data, and evaluation of the patients' clinical symptoms. The results obtained after six months and one year were compared within and between each group. At six months follow-up, CT findings had improved or were unchanged in 11 patients(69 %) in group A, and four patients(27 %) in group B(p = 0.032). In ten patients in each group, the level of alpha-fetoprotein was above 200 ng/ml. Its level was decreased in five patients(50 %) and three patients(30 %), respectively. The six-month survival rate was 81 % (13/16) in group A and 67% (10/15) in group B (p 0.43), while the one-year survival figures for these two groups were 50 % (8/16) and 20 % (3/15), respectively(p = 0.135). In group A, the CT findings were steady in five out of eight patients(63 %), while in groupB, CT findings showed that tumors with increased alpha-fetoprotein levels had increased in size and/or number. In group A, it was found that in two (33 %) of six

We have previously shown that some variability exists in the degree of collagen binding between different strains of heat-killed, formaldehyde-fixed S. aureus which are commercially available as immunologic reagents. The present study demonstrates that live S. aureus of the Cowan 1 strain binds amounts of collagen per organism equivalent to those demonstrated previously in heat-killed, formaldehyde-fixed bacteria but has an affinity over 100 times greater, with Kd values of 9.7 X 10(-11) M and 4.3 X 10(-8) M for live and heat-killed organisms, respectively. Studies were also carried out with S. aureus killed by ionizing radiation, since this method of killing the organism seemed less likely to alter the binding moieties on the surface than did heat killing. Bacteria killed by exposure to gamma radiation bound collagen in a manner essentially indistinguishable from that of live organisms. Binding of collagen to irradiated cells of the Cowan 1 strain was rapid, with equilibrium reached by 30 min at 22 degrees C, and was fully reversible. The binding was not inhibited by fibronectin, fibrinogen, C1q, or immunoglobulin G, suggesting a binding site for collagen distinct from those for these proteins. Collagen binding was virtually eliminated in trypsin-treated organisms, indicating that the binding site has a protein component. Of four strains examined, Cowan 1 and S. aureus ATCC 25923 showed saturable, specific binding, while strains Woods and S4 showed a complete lack of binding. These results suggest that some strains of S. aureus contain high-affinity binding sites for collagen. While the number of binding sites per bacterium varied sixfold in the two collagen-binding strains, the apparent affinity was similar

    PurposeTo describe the radiologic findings and imaging response of hepatocellular carcinoma (HCC) supplied by the lumbar artery.MethodsBetween April 2004 and December 2012, we encountered HCC supplied by a lumbar artery in 21 patients. Two investigators retrospectively reviewed clinical and radiological findings of HCC supplied by the lumbar artery using computed tomography (CT) scans and digital subtraction angiograms.ResultsPatients had received 1–27 sessions of previous chemoembolization procedures (mean 7.7 sessions, median 4 sessions). Mean tumor size was 5.3 cm. The locations of HCC supplied by lumbar artery were the bare area (n = 14, 67 %) and segment VI (n = 7, 33 %). Tumor-feeding arteries arose from the main lumbar artery (n = 7), proximal anterior division (n = 4), and distal anterior division (n = 14). In 20 patients, selective chemoembolization through the tumor-feeding arteries of the lumbar artery was achieved. In 1 patient, nonselective embolization at the main lumbar artery was performed. There was no complication such as skin necrosis or paralysis. On the first follow-up enhanced CT scan, target tumors fed by the lumbar artery showed complete response (n = 6), partial response (n = 4), stable disease (n = 3), and progressive disease (n = 8), but overall tumor response was partial response (n = 1) and progressive disease (n = 20).ConclusionWhen HCC is located in the inferior tip or bare area of the liver, a lumbar artery may supply the tumor. Although selective chemoembolization via the tumor-feeding vessel of the lumbar artery can be achieved in most cases, overall tumor response is commonly unfavorable.

  12. Chronic complicated osteomyelitis

    International Nuclear Information System (INIS)

    Fourteen patients with prior trauma and/or surgery of the lower extremity and suspected active chronic osteomyelitis underwent MR imaging. Eleven patients also underwent In-111 scanning. All patients had surgical confirmation, MR imaging could assess the extent of abnormal marrow and distinguish abnormal marrow due to granulation tissue from active osteomyelitis. The presence and extent of soft-tissue infection could be determined and distinguished from bone involvement in spite of tissue distortion. The course and origin of sinus tracts could be followed. MR imaging was more sensitive to active infection than In-111 scanning. All 11 cases of active osteomyelitis were correctly diagnosed with MR imaging. In-111 scans were positive in only five of the eight cases of active infection in which scans were obtained. MR imaging is useful in chronic complicated osteomyelitis

    Chemoradiotherapy protocols are a recent development in the management of tumours where preservation of organ function is important. It is now recognized that such combined treatment may produce adverse effects below the accepted dose thresholds for either modality. This enhancement of toxicity is generally thought to reflect depletion of stem cells within the tissue concerned. We report four patients who have developed avascular necrosis or fractures of the hip following chemoradiotherapy for carcinoma of the vulva or anus. These complications developed after a radiation dose of 4500 cGy in 20 fractions. The possible role of cytotoxic agents in sensitizing bone to radiation damage is discussed, and a novel mechanism is proposed to account for this phenomenon. (author).

    Cancer is becoming a treatable and even often curable disease. The neuromuscular system can be affected by direct tumor invasion or metastasis, neuroendocrine, metabolic, dysimmune/inflammatory, infections and toxic as well as paraneoplastic conditions. Due to the nature of cancer treatment, which frequently is based on a DNA damaging mechanism, treatment related toxic side effects are frequent and the correct identification of the causative mechanism is necessary to initiate the proper treatment. The peripheral nervous system is conventionally divided into nerve roots, the proximal nerves and plexus, the peripheral nerves (mono- and polyneuropathies), the site of neuromuscular transmission and muscle. This review is based on the anatomic distribution of the peripheral nervous system, divided into cranial nerves (CN), motor neuron (MND), nerve roots, plexus, peripheral nerve, the neuromuscular junction and muscle. The various etiologies of neuromuscular complications - neoplastic, surgical and mechanic, toxic, metabolic, endocrine, and paraneoplastic/immune - are discussed separately for each part of the peripheral nervous system.

    2008-01-01

    Microscopic forms of colitis have been described, including collagenous colitis. This disorder generally has an apparently benign clinical course. However, a number of gastric and intestinal complications, possibly coincidental, may develop with collagenous colitis. Distinctive inflammatory disorders of the gastric mucosa have been described, including lymphocytic gastritis and collagenous gastritis. Celiac disease and collagenous sprue (or collagenous enteritis) may occur. Colonic ulceration has been associated with use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn's disease, may evolve from collagenous colitis. Submucosal "dissection", colonic fractures or mucosal tears and perforation from air insufflation during colonoscopy may occur and has been hypothesized to be due to compromise of the colonic wall from submucosal collagen deposition. Similar changes may result from increased intraluminal pressure during barium enema contrast studies. Finally, malignant disorders have also been reported, including carcinoma and lymphoproliferative disease.

  17. Topography of the accessory left gastric artery (ALGA) analyzed by CT angiography from the left hepatic artery

    International Nuclear Information System (INIS)

    To avoid gastric complications when we perform transcatheter treatment via left hepatic artery, we analyzed the topography of ALGA (accessory left gastric artery) by left hepatic arteriography and CT angiography from left hepatic artery. Six hundred seventy eight cases of CT angiography were performed between 1995 and 2000. Among them, selective left hepatic arteriography was done in 85 cases. We analyzed the frequency and the course of ALGA on the hepatic angiogram and CT angiogram. ALGA were identified in eighteen (21.2 %) of the 85 cases. We classified them into eleven cases of the proximal type and six cases of the distal type. When ALGA bifurcated from the left hepatic artery very close to the bifurcation of A2 (dorsolateral branch) and A3 (ventrolateral branch), we classified them as the distal type on hepatic angiogram. On the other hand, when ALGA bifurcated from the left hepatic artery apart from the bifurcation of A2 and A3 they were classified as the proximal type. In one rare case ALGA originated from the dorsolateral branch of the left hepatic artery. ALGA were classified as the distal and proximal types. Distal type of ALGA often overlapped dorsolateral branch of the left hepatic artery, and it was sometimes difficult to notice the existence of them. We should check the existence of ALGA on the arterial phase of dynamic CT before we plan to make a transcatheter treatment from the left hepatic artery. Then we can avoid gastric complications caused by a transcatheter treatment from the left hepatic artery. (author)

  18. Staphylococcus aureus – antimicrobial resistance and the immunocompromised child

    2014-05-01

    Full Text Available J Chase McNeilDepartment of Pediatrics, Section of Infectious Diseases, Baylor College of Medicine, Houston, TX, USAAbstract: Children with immunocompromising conditions represent a unique group for the acquisition of antimicrobial resistant infections due to their frequent encounters with the health care system, need for empiric antimicrobials, and immune dysfunction. These infections are further complicated in that there is a relative paucity of literature on the clinical features and management of Staphylococcus aureus infections in immunocompromised children. The available literature on the clinical features, antimicrobial susceptibility, and management of S. aureus infections in immunocompromised children is reviewed. S. aureus infections in children with human immunodeficiency virus (HIV are associated with higher HIV viral loads and a greater degree of CD4 T-cell suppression. In addition, staphylococcal infections in children with HIV often exhibit a multidrug resistant phenotype. Children with cancer have a high rate of S. aureus bacteremia and associated complications. Increased tolerance to antiseptics among staphylococcal isolates from pediatric oncology patients is an emerging area of research. The incidence of S. aureus infections among pediatric solid organ transplant recipients varies considerably by the organ transplanted; in general however, staphylococci figure prominently among infections in the early posttransplant period. Staphylococcal infections are also prominent pathogens among children with a number of immunodeficiencies, notably chronic granulomatous disease. Significant gaps in knowledge exist regarding the epidemiology and management of S. aureus infection in these vulnerable children.Keywords: pediatric, HIV, cancer, transplant

    2015-03-01

    Infected diabetic foot is the most common reason for hospitalization and complications in patients with type 2 diabetes mellitus (DM2). Methicillin-resistant Staphylococcus aureus (MRSA) is frequently isolated from such lesions, and its presence is growing, seriously deteriorating the infected patient's quality of life. The aim of this study was to assess the prevalence of MRSA as well as other microbiota in 100 patients diagnosed with (DM2) and with infected foot ulcers at the Hospital General de Mexico. The main results obtained show a prevalence of Staphylococcus aureus (42%), followed by Escherichia coli (36%) and, in lower percentages, other bacteria. MRSA was predominant (34%), and we conclude that the use of cefoxitin instead of oxacillin as the first-choice antibiotic has an advantage because it is a better inducer of methicillin-resistance expression.

    2014-01-01

    Splenomegaly is a common sequela of cirrhosis, and is frequently associated with decreased hematologic indices including thrombocytopenia and leukopenia. Partial splenic artery embolization (PSE) has been demonstrated to effectively increase hematologic indices in cirrhotic patients with splenomegaly. This is particularly valuable amongst those cirrhotic patients who are not viable candidates for splenectomy. Although PSE was originally developed decades ago, it has recently received increased attention. Presently, PSE is being utilized to address a number of clinical concerns in the setting of cirrhosis, including: decreased hematologic indices, portal hypertension and its associated sequela, and splenic artery steal syndrome. Following PSE patients demonstrate significant increases in platelets and leukocytes. Though progressive decline of hematologic indices occur following PSE, they remain improved as compared to pre-procedural values over long-term follow-up. PSE, however, is not without risk and complications of the procedure may occur. The most common complication of PSE is post-embolization syndrome, which involves a constellation of symptoms including fever, pain, and nausea/vomiting. The rate of complications has been shown to increase as the percent of total splenic volume embolized increases. The purpose of this review is to explore the current literature in regards to PSE in cirrhotic patients and to highlight their techniques, and statistically summarize their results and associated complications.

    2015-10-01

    Full Text Available At the final stages of a coronary artery bypass graft operation on a 64-year-old man, an experienced physician attempted to insert an intra-aortic balloon pump into the femoral artery via the Seldinger technique. However, while the balloon pump was being passed over the guide wire, the latter was completely lost.The guide wire should be held at the tip at all times to prevent passage into the vessel. Strict adherence to this rule will prevent guide-wire loss, which is, albeit rare and completely avoidable, a potentially life-threatening complication of central vein or artery catheterization, with reported fatality rates of up to 20% when the whole wire is lost. The literature contains several reports on guide-wire loss during central venous, arterial, and hemodialysis catheterization, but we report for the first time the loss of a guide wire as a rare complication of intra-aortic balloon pump insertion.

  7. A new puncture needle (Seldinger technique) for easy antegrade catheterization of the superficial femoral artery

    International Nuclear Information System (INIS)

    Mainly for anatomical reasons a guide-wire or a catheter has a tendency to turn into the deep femoral artery during antegrade catheterization of the lower limb. To overcome this problem a curved puncture needle has been designed which allows positioning of the guide-wire in an anterior direction. Antegrade catheterization of the superficial femoral artery was achieved in 25 patients without lengthy manipulations or complications. With this technique the rate of complications at antegrade catheterization will probably be reduced. (orig.)

    Although conventional intraarterial digital subtraction angiography remains the gold standard method for imaging the vertebral artery, noninvasive modalities such as ultrasound, multislice computed tomographic angiography and magnetic resonance angiography are constantly improving and are playing an increasingly important role in diagnosing vertebral artery pathology in clinical practice. This paper reviews the current state of vertebral artery imaging from an evidence-based perspective. Normal anatomy, normal variants and a number of pathological entities such as vertebral atherosclerosis, arterial dissection, arteriovenous fistula, subclavian steal syndrome and vertebrobasilar dolichoectasia are discussed.

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical application of interventional therapy in treating massive abdominal and pelvic arterial hemorrhage. Methods: Sixty-seven patients with massive abdominal or pelvic arterial hemorrhage were collected for this study. The bleeding sites included gastroduodenal artery (n=11), superior mesenteric artery (n=15), inferior mesenteric artery (n=6), renal artery (n=12) and internal iliac artery branches (n=23). With Seldinger's technique the femoral artery was punctured, which was followed by angiography in order to visualize and to confirm the bleeding arteries, and then by using the gelatin sponge particles, coils or micro-coil, PVA particles or granules of sodium alginate the bleeding arteries were occluded. All the patients were observed closely after the operation, focusing on the vital signs. And follow-up observation and examine were conducted regularly. Results: Of the 67 patients,successful embolization with single procedure was obtained in 65, with twice procedures in one. The remaining one patient had to receive surgery as there was still small amounts of bleeding after embolization. The total success rate was 98.5%. Fifty patients were followed up for 3 months to 2 years after the arterial embolization (mean 12 months), and no severe complications or recurrence occurred. Conclusion: Interventional embolization is a safe and effective treatment for massive abdominal and pelvic arterial bleeding. It can precisely and instantly occlude the bleeding arteries. The key point of technical success is the proficient super-selective catheterization skill. (authors)

    International Nuclear Information System (INIS)

    Objective: To examine the possible local damaging effects of arterial monitoring catheters on arterial functioning in patients after elective surgery with color Doppler ultrasound. Methods: Thirty patients who underwent elective surgery with a radial artery catheter were examined. The 2-dimentional ultrasonography and the blood flow of each radial and ulnar artery were examined before the puncture, 30 minutes and 24-hour after removal. Artery diameter, peak velocity of blood flow and patency were examined. The blood flow velocity of ulnar artery/the blood flow velocity of radial artery ratio were compared. The non-affected arm was used as the control. Results: Artery monitoring catheters caused a remarkable functional arterial change in the affected arm. The blood flow velocity of ulnar artery/the blood flow velocity of radial artery ratio were increased 30 minutes and 24 hour after removal. There were no severe clinical complications. Conclusion: Radial artery blood flow can be observed clearly with color Doppler ultrasound. Aseries of data were measured and recorded. There is significant change in the hemodynamic function of the artery during certain period of time. (authors)

    Retroperitoneal and pelvic infections complications are the major types of genito-urinary complications in Crohn's disease. CT has been shown to be a sensitive, non invasive method of documenting these infectious complications. On the other hand, conventional studies are more sensitive than CT to detect genitourinary fistulae. Some complications may manifest few or no symptom as urinary obstruction and nephrolithiasis, detected easily by sonography. For these reasons, it is important for radiologists to be aware of the genito-urinary complications of Crohn's disease. (authors). 42 refs., 20 figs

Methodology: Clinical samples from respiratory tract, blood, pus and various catheter tips routinely received in the Department of Microbiology, Army Medical College, Rawalpindi were innoculated on blood and MacConkey agar. Staphylococcus aureus was identified by colony morphology, Gram reaction, catalase test and coagulase test. Methicillin resistant Staphylococcus aureus detection was done by modified Kirby Bauer disc diffusion method using cefoxitin disc (30g) and the isolates were considered methicillin resistant if the zone of inhibition around cefoxitin disc was /sup 2/ 21 mm. Bacterial suspensions of 56 Staphylococcus aureus isolates and 50 MRSA isolates were prepared, which were standardized equal to 0.5 McFarland's turbidity standard and inoculated on Mueller-Hinton agar plates followed by application of ceftaroline and linezolid disc (Oxoid, UK), according to manufacturer's instructions. The plates were then incubated at 37 Degree C aerobically for 18 - 24 hours. Diameters of inhibition zone were measured and interpretated as per Clinical and Laboratory Standards Institute (CLSI) guidelines. Results: Out of 106 isolates all of the 56 Staphylococcus aureus (100%) were sensitive to ceftaroline and linezolid. However, out of 50 methicillin resistant Staphylococcus aureus, 48 (96%) were sensitive to ceftaroline whereas, 49 (98%) were sensitive to linezolid. Conclusion: Ceftaroline is equally effective as linezolid against Staphylococcus aureus and methicillin resistant Staphylococcus aureus. (author)

    Pulmonary arterial hypertension (PAH) is a rare disorder characterized by progressive obliteration of the pulmonary microvasculature, resulting in elevated pulmonary vascular resistance and premature death. According to the current classification, PAH can be associated with exposure to certain drugs or toxins, particularly appetite suppressant drugs, such as aminorex, fenfluramine derivatives and benfluorex. These drugs have been confirmed to be risk factors for PAH and were withdrawn from the market. The supposed mechanism is an increase in serotonin levels, which was demonstrated to act as a growth factor for the pulmonary arterial smooth muscle cells. Amphetamines, phentermine and mazindol were less frequently used but are also considered as possible risk factors for PAH. Dasatinib, a dual Src/Abl kinase inhibitor, used in the treatment of chronic myelogenous leukaemia was associated with cases of severe PAH, in part reversible after its withdrawal. Recently several studies raised the potential endothelial dysfunction that could be induced by interferon, and few cases of PAH have been reported with interferon therapy. Other possible risk factors for PAH include: nasal decongestants, like phenylpropanolamine, dietary supplement - L-Tryptophan, selective serotonin reuptake inhibitors, pergolide and other drugs that could act on 5HT2B receptors. Interestingly, PAH remains a rare complication of these drugs, suggesting possible individual susceptibility and further studies are needed to identify patients at risk of drugs induced PAH.

  12. MR imaging of vascular and biliary complications after liver transplantation

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of MR angiography and cholangiopancreatography on the diagnosis of vascular and biliary complications after liver transplantation. Methods: Seven consecutive adult patients underwent 16 MR imaging examinations after orthotopic liver transplantation using a breath-hold 2D TSE and FLASH. MR cholangiopancreatography and triphasic contrast-enhanced 3D imaging (average dose, 0.30 mmol/kg of Gd-DTPA) was performed and imaging findings after liver transplantation was analyzed. Results: Two normal cases showed a small amount of ascites or fluid in the perihepatic region or the intersegmental fissure of the transplanted liver, as well as transient right-sided pleural effusion and mild lymph swelling. Four cases had vascular complication including elongation and kinking of hepatic artery, aneurysm formation of donor's hepatic artery, narrowing of the portal vein at the anastomosis and clubbed dilataltion of hepatic veins. Three cases had biliary complications including anastomotic and nonanastomotic strictures, mucocele and bile leakage. Conclusion: Dynamic enhanced 3D MR angiography imaging combined with MR cholangiopancreatography can provide a comprehensive assessment of vascular and biliary complications in most recipients of liver transplants. MR imaging after liver transplants is significative to guide the diagnosis and treatment. (authors)

  13. Percutaneous treatment of complications occurring during hemodialysis graft recanalization

    International Nuclear Information System (INIS)

    Introduction/objective: To describe and evaluate percutaneous treatment methods of complications occurring during recanalization of thrombosed hemodialysis access grafts. Methods and materials: A retrospective review of 579 thrombosed hemodialysis access grafts revealed 48 complications occurring during urokinase thrombolysis (512) or mechanical thrombectomy (67). These include 12 venous or venous anastomotic ruptures not controlled by balloon tamponade, eight arterial emboli, 12 graft extravasations, seven small hematomas, four intragraft pseudointimal 'dissections', two incidents of pulmonary edema, one episode of intestinal angina, one procedural death, and one distant hematoma. Results: Twelve cases of post angioplasty ruptures were treated with uncovered stents of which 10 resulted in graft salvage allowing successful hemodialysis. All arterial emboli were retrieved by Fogarty or embolectomy balloons. The 10/12 graft extravasations were successfully treated by digital compression while the procedure was completed and the graft flow was restored. Dissections were treated with prolonged Percutaneous Trasluminal Angioplasty (PTA) balloon inflation. Overall technical success was 39/48 (81%). Kaplan-Meier Primary and secondary patency rates were 72 and 78% at 30, 62 and 73% at 90 and 36 and 67% at 180 days, respectively. Secondary patency rates remained over 50% at 1 year. There were no additional complications caused by these maneuvers. Discussions and conclusion: The majority of complications occurring during percutaneous thrombolysis/thrombectomy of thrombosed access grafts, can be treated at the same sitting allowing completion of the recanalization procedure and usage of the same access for hemodialysis

  14. Computer-assisted 3D reconstruction of the terminal branches of the cerebral arteries. Pt. 3. Posterior cerebral artery and circle of Willis

    International Nuclear Information System (INIS)

    We present a three-dimensional anatomical computer model of the terminal branches of the posterior cerebral artery and circle of Willis, acquired from equidistant serial anatomical slices of three brains. The reconstructions provide a clear picture from all angles of the complicated course of the terminal branches of the cerebral arteries. This can help to identify the arteries in conventional and magnetic resonance angiography. Our rendition of the cerebral arteries can be matched with CT, MR and PET images to indicate the areas of extension of the individual branches, allowing neuromorphological and functional correlations.

    Endovascular procedures are becoming the standard type of care for the management of hemodialysis vascular access dysfunction. As with any type of medical procedure, these techniques can result in procedure-related complications, although the expected number of complications is low. The clinical extent of these complications varies from case to case. Management of these cases depends on the clinical presentation. Major complications such as vein rupture, arterial embolism, remote site bleeding or hematoma, symptomatic pulmonary embolism and puncture site complications necessitating treatment require major therapy. Minor complications such as non-flow compromising small puncture site hematoma or pseudoaneurysms require little or no therapy. It is essential that the interventionist be prepared to manage these complications appropriately when they arise.

  16. Sickle cell disease complications

    Full Text Available Sickle cell disease (SCD is an inherited, lifelong condition. The sickle mutation consists a single nucleotide change (GAT->GTT in the sixth codon of exon 1 of the β-globin gene coding for the β-globin polypeptide of hemoglobin (Hb (a2β2. This change results in replacement of the wild type glutamic acid residue by a valine residue in β-globin chain and the formation of the sickle Hb (HbS in homozygotes for this mutation. Heterozygotes live a normal life. In SCD patients, sickle erythrocytes are rigid with decreased deformability and reduced life span resulting in hemolysis, vaso-occlusive disease, vasculopathy and subsequent inflammation and end organ damage. Sickle cell disease affects millions of people worldwide. Today, with proper health care, many SCD patients have a good quality of life (QoL and are in fairly good health most of the time. These people can live up to their forties or fifties, or longer. Despite the ‘common’ underlying genetic basis and a similar pathophysiology, patients with SCD present a highly variable clinical phenotype due to Single Nucleotide Polymorphisms (SNPs variability throughout the genome. Patients with SCD are at high risk for developing multisystem acute and chronic complications associated with significant morbidity and mortality.

    Pregnancy induces a number of physiologic changes that affect the hematologic indices, either directly or indirectly. Recognizing and treating hematologic disorders that occur during pregnancy is difficult owing to the paucity of evidence available to guide consultants. This review discusses specifically the diagnosis and management of benign hematologic disorders occurring during pregnancy. Anemia secondary to iron deficiency is the most frequent hematologic complication and is easily treated with oral iron formulations; however, care must be taken not to miss other causes of anemia, such as sickle cell disease. Thrombocytopenia is also a common reason for consulting the hematologist, and distinguishing gestational thrombocytopenia from immune thrombocytopenia (ITP), preeclampsia, HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets), or thrombotic thrombocytopenic purpura (TTP) is essential since the treatment differs widely. Occasionally the management of mother and infant involves the expeditious recognition of neonatal alloimmune thrombocytopenia (NAIT), a condition that is responsible for severe life-threatening bleeding of the newborn. Additionally, inherited and acquired bleeding disorders affect pregnant women disproportionately and often require careful monitoring of coagulation parameters to prevent bleeding in the puerperium. Finally, venous thromboembolism (VTE) during pregnancy is still largely responsible for mortality during pregnancy, and the diagnosis, treatment options and guidelines for prevention of VTE during pregnancy are explored.

    Gastrointestinal (GI) complications are an uncommon but potentially devastating complication of cardiac surgery. The reported incidence varies between .3% and 5.5% with an associated mortality of .3-87%. A wide range of GI complications are reported with bleeding, mesenteric ischemia, pancreatitis, cholecystitis, and ileus the most common. Ischemia is thought to be the main cause of GI complications with hypoperfusion during cardiac surgery as well as systemic inflammation, hypothermia, drug therapy, and mechanical factors contributing. Several nonischemic mechanisms may contribute to GI complications, including bacterial translocation, adverse drug reactions, and iatrogenic organ injury. Risk factors for GI complications are advanced age (>70 years), reoperation or emergency surgery, comorbidities (renal disease, respiratory disease, peripheral vascular disease, diabetes mellitus, cardiac failure), perioperative use of an intra-aortic balloon pump or inotrope therapy, prolonged surgery or cardiopulmonary bypass, and postoperative complications. Multiple strategies to reduce the incidence of GI complications exist, including risk stratification scores, targeted inotrope and fluid therapy, drug therapies, and modification of cardiopulmonary bypass. Currently, no single therapy has consistently proven efficacy in reducing GI complications. Timely diagnosis and treatment, while tailored to the specific complication and patient, is essential for optimal management and outcomes in this challenging patient population. PMID:25208431

  19. Renal artery stenosis after radiotherapy for Ewing's sarcoma

    International Nuclear Information System (INIS)

    Background: the fact that therapeutic irradiation can induce significant stenosis in the arteries of the head, neck, and chest, as welt as in the aorta and the iliac arteries, is familiar in daily practice and well documented in the literature. By contrast, radiation-induced renal artery stenosis seems to be a less widely known complication. Patients and methods: the sudden onset of medically refractory arterial hypertension and coma in a 27-year-old man is reported, who had been treated at age 20 with chemotherapy and radiotherapy for Ewing's sarcoma in the lumbar region. This treatment had been performed at the hospital of Sion, Switzerland in 2001. Also, the relevant literature from 1965 to 2007 is reviewed to underscore various aspects of this problem and to demonstrate the clinical relevance of renal artery stenosis as a potential long-term sequela of radiotherapy. Conclusion: radiation-induced renal artery stenosis has only rarely been described in the literature, but arterial hypertension due to radiation-induced renal artery stenosis is a serious long-term sequela that can appear at a latency of up to 20 years after treatment. The paucity of reports presumably reflects the lesser frequency of radiotherapy for retroperitoneal tumors as compared to head-and-neck cancers, as well as lower awareness of the problem due to diagnostic bias in the era before CT and MRI were in routine use: at that time, carotid artery stenosis was easy to diagnose by ultrasonography, while radiation-induced renal artery stenosis, whose real incidence may well be higher, probably often went undetected. Thus, when a patient with a history of abdominal or retroperitoneal radiotherapy unexpectedly develops intractable hypertension, radiation-induced renal artery stenosis must be included in the differential diagnosis.

  20. VARIABILITY OF ORIGIN OF OBTURATOR ARTERY AND ITS CLINICAL SIGNIFICANCE

    Directory of Open Access Journals (Sweden)

    Sakthivel

    2015-12-01

    Full Text Available Background: Obturator artery is a branch of anterior division of internal iliac artery. It normally runs anteroinferiorly on the lateral wall of pelvis to the upper part of the obturator foramen and leaves the pelvis by passing through the obturator canal. On its course, the artery is accompanied by the obturator nerve and vein. It supplies the muscles of the medial compartment of the thigh. A severe and potentially lethal complication in pelvic injuries is arterial bleeding commonly involving the branches of the internal iliac artery, namely the lateral sacral, iliolumbar, obturator, vesical and inferior gluteal arteries. A sound knowledge of retro-pubic pelvic vascular anatomy is pivotal for successful performance of endoscopic procedures such as total extra-peritoneal inguinal hernioplasty or laparoscopic herniorraphy. The context and purpose of the study: This study is an attempt to analyse the origin, course, distribution of obturator artery in pelvis and their clinical implication. Result: out of 60 formalin fixed pelvic halves 36.6% of the specimens, (26.67% in males and 10% in females the origin of obturator artery was found to be normal from anterior division of internal iliac artery. About 63.63% from various other sources. Conclusion: This knowledge of variation in the origin of obturator artery is important while doing pelvic and groin surgeries requiring appropriate ligation. Such aberrant origins may be a significant source for persistent bleeding in the setting of acute trauma. Knowledge regarding the variations of obturator artery is useful during surgeries of fracture and direct or indirect inguinal, femoral and obturator hernias.
