Abstract: The number of end stage of renal disease patients that need dialysis or renal transplantation increased in the world.
Insertion and maintenance functional vascular access remain the challenging problem. Arteriovenous fistula is the common access for
dialysis but complication and its failure is the main problem. The aim of this study is to evaluate patients with arteriovenous fistula
during 4 years and describe the probable influenced factors on fistula patency. In this analytical descriptive study, we fallowed 245
patients during 4 years and evaluated them for primary failures and effective factors on vascular patency. The patients were asked
about demographic data, how to caring condition arteriovenous fistula, dialysis and complications. The mean age of the patients was
47.77 years. The underline diseases were hypertension (43.3%), hypertension and diabetes mellitus (21.2%) and diabetes mellitus
(4.5%). According Log rank test there were meaningful results between arteriovenous patency with sex and dialysis (P < 0.05). Our
result of primary patency at 6 months, 1, 2, 3 and 4 years for all patients were 79.5%, 70%, 65%, 60.5% and 48%. Our study showed
dialysis could increase the fistula patency rate. Other factors were not associated with primary patency. It seems ESRD patients
undergoing dialysis have better fistula patency, may be due to homeostasis abnormalities induced by their particular conditions.
