Introduction: the arteriovenous fistula is an important surgical technique for treating patients with chronic renal failure since successful hemodialysis depends on this vascular access. Objective: to determine the behavior of the arteriovenous fistula for hemodialysis in patients with chronic renal failure. Methods: study of 53 patients who had been operated on by the arteriovenous fistula technique at "Victoria" hospital of Mahe, Seychelles Islands from April 2010 through November 2011. The study variables were age, sex, related diseases, location of the fistula, its use in the hemodialysis and complications. Results: most of the patients were males aged 41 to 60 years and all suffered from hypertension. Seventy one arteriovenous fistulas were applied through termino lateral anastomosis: 27 (38.02 %) radiocephalic, 37 (52.11 %) humerus-cephalic, 6 (8.45 %) humerus-basilic and 1 (1.4 %) femorofemoral with polytetrafluoroethylene prosthesis. Of this group, 44 fistulas (61.9 %) worked well and 33 (75 %) were useful in hemodialysis. Complications were found in 24 (33.8 %) with higher thrombosis frequency in 20 (28.2 %) especially in the radiocephalic type (14). Infection occurred as a result of the use of the prosthesis. Six people (8.4 %) died of disease complications. Conclusions: Good results were achieved in performing arteriovenous fistulae with this surgical procedure in spite of the difficulties in obtaining the outpatients' consent to be operated on before applying hemodialysis.

Keywords : arteriovenous fistula; chronic renal failure; hemodialysis; complications.
