arteriovenous fistula is considered as a prerequisite in patients with chronic renal failure undergoing hemodialysis. the purpose of this study was to compare the effectiveness and side effects if any of native vein and synthetic grafts in these patients. from april 2002 till july 2003, a total of 37 patients were referred to us for the utilization of these grafts. in 16 out of these patients w...

A unique case of recurrent brain abscess as the primary manifestation of pulmonary arteriovenous fistula is presented. In the absence of hematologic abnormalities and characteristic physical findings, the diagnosis of pulmonary arteriovenous fistula is particularly elusive. Patients with brain abscess must be carefully evaluated for the presence of pulmonary arteriovenous fistula or hereditary ...

We report a case of a 40 year old man with portal hypertension caused by a splenic arteriovenous fistula that was diagnosed at laparotomy. He presented with bleeding esophageal varices and was initially treated by sclerotherapy. At laparotomy, portal pressure was 40 cmH20 but fell to 20 cm H20 after the fistula was treated with splenectomy. All symptoms disappeared shortly after operation ...

OBJECTIVE To evaluate the two year patency rate of functioning arteriovenous fistula. METHODOLOGY This prospective case series study was conducted at Department of Urology, Jinnah Postgraduate Medical Centre, Karachi, from 1(st) January 2009 to 31(st) December, 2010. Patients were chosen for CBRC arteriovenous fistula at wrist and patients undergoing other types of vascular access or secondar...

Arteriovenous fistula dysfunction is a frequent complication in, and hindrance to, patients with end stage kidney disease undergoing renal replacement therapy with intermittent haemodialysis. We present an unusual complication in a 68-year-old male patient undergoing haemodialysis therapy for end stage kidney failure caused by biopsy-proven multiple myeloma. We explore the occurrence of an extr...

Two patients, who were on hemodialysis over a femoral arteriovenous fistula, were transplanted in our center. Despite adequate blood pressure, perfusion of the renal allograft remained poor after completion of the vascular anastomoses. Ligation of the femoral arteriovenous fistula (1.6 L/min) led to adequate perfusion. Initial graft function was good. Although it remains unclear whether ischemi...

UNLABELLED INTRODUCTION Iatrogenic arteriovenous fistula is a vascular condition that may result from coronary angiography. Many case reports have described arteriovenous fistula occurrence after coronary angiography using the transfemoral access route, but rarely as a complication of using the transradial approach. We report a rare case of a patient with arteriovenous fistula following tran...

Time-resolved, contrast-enhanced 3D MR angiography combined with parallel imaging at 3T was applied to an intracranial arteriovenous malformation, a dural arteriovenous fistula, and an extracranial facial arteriovenous malformation. The temporal resolution was one image every 1.5 seconds. Arterial feeders were depicted in all three cases. Early venous drainage was observed in the intracerebral ...

the klippel-trenaunay syndrome, first reported in 1910, is a triad of cutaneous hemangioma, varicose veins, and soft tissue or bony hypertrophy. the varicosities are extensive involving the tributaries of the greater or lesser saphenous systems. arteriogram are normal with no evidence of arteriovenous fistulas. multiple ligation and stripping may worsen the condition, and treatment consists of ...

background and objectives: arteriovenous fistula is a popular vascular access method for surgical treatmentof hemodialysis patients. the method, however, is associated with a high rate of early failure varying in the range of 20-60%. predicting early arteriovenous fistula failure and its risk factors can help reduce its incidence, its hospitalization rate, and associated costs. in this study, w...
