OBJECTIVE: To describe a technique for creating an arteriovenous fistula as an access to hemodialysis, evaluating its technical aspects, efficacy and complications. METHOD: From August 1998 to October 2000, 16 superficial saphenofemoral arteriovenous fistulas were performed in 15 patients. These procedures were used in patients without access options in upper limbs. The surgical technique consisted of an anteriorization and a superficialization of the saphenous vein anastomosed to the superficial femoral artery in the distal portion. The superficial saphenofemoral arteriovenous fistulas were evaluated with regard to puncture, appropriate flow, spontaneous venous pressure, dialysis adequacy and intraoperative complications. RESULTS: There were no intraoperative complications and all the fistulas could be successfully concluded. There was one early death, but the other fistulas were able to the hemodialysis in the 30th postoperative day. Fourteen fistulas were used; in the evolution, three patients were submitted to renal transplant, four presented thrombosis and two presented puncture pseudoaneurysm. CONCLUSION: Superficial saphenofemoral arteriovenous fistulas proved to be a good alternative for patients who do not have other possibilities of vascular access in upper limbs, thus allowing an effective hemodialysis treatment, with a good patency rate at medium term.
