Background: In patients with chronic renal failure, a major concern is to provide safe and reliable long-term vascular access for haemodialysis. The radiocephalic arteriovenous (AV)fistula remains thefirst choice vascular access procedure, however the grafts are, used in order to obtain vascular access in patients with failed native distal and proximal AV fistulas. The aim of this study was to compare the patency rate of different . grafts such as standard wall polytetrafluoroethylene (sPTFE), bovine vein graft, Diastat graft, in these patients.
