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...

Whenever possible it is suggested that a native arteriovenous fistula is created and used for haemodialysis, as it is superior to an arteriovenous graft and to a central venous catheter. (Level III evidence) When a native arteriovenous fistula is not possible, an artificial arteriovenous graft should be used in preference to a central venous catheter. Arteriovenous grafts have similar patency t...

BACKGROUND AND OBJECTIVES Arteriovenous fistulas often fail to mature, and nonmaturation has been attributed to postoperative stenosis caused by aggressive neointimal hyperplasia. Preexisting intimal hyperplasia in the native veins of uremic patients may predispose to postoperative arteriovenous fistula stenosis and arteriovenous fistula nonmaturation. DESIGN, SETTING, PARTICIPANTS, & MEASURE...

patients with end stage renal disease need a good vascular access for hemodialysis. arteriovenous fistula is the method of choice for vascular access in these patients. however, failure of arteriovenous fistula due to thrombosis is a major problem. the aim of this study was to evaluate the effect of the heparin on the patency of the arteriovenous fistula. this prospective interventional case co...

The long-term survival and quality of life of patients on haemodialysis is dependent on the adequacy of dialysis via an appropriately placed vascular access. The native arteriovenous fistula at the wrist is generally accepted as the vascular access of choice in haemodialysis patients due to its low complication and high patency rates. It has been shown beyond doubt that an optimally functioning...

Background: Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. Case Presentation: Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out ot...

Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...
