Abstract Objectives To compare the outcome of autogenous arteriovenous fistulas (AVF) with interposition graft fistulas for hemodialysis access. Design Retrospective clinical study. Setting Department of Surgery, Zurich University Hospital. Methods Primary and secondary patency rates were calculated by life tables. Factors potentially affecting patency were studied by comparison of life tables using the log rank test. Main results From 1980 to 1992, 414 patients were operated on for long‐term vascular access. 720 fistulas were created including 429 AVF and 291 interposition grafts (150 bovine xenografts, 69 PTFE grafts, 59 sheep collagen grafts, 10 autologous and 1 homologous vein grafts). Secondary patency rates after 1 and 3 yr were 74/64% in AVF, 56/24% in bovine xenografts, 58/40% in PTFE grafts and 71/45% in sheep collagen grafts. The latter performed not significantly worse than AVF. Primary and secondary patency rates were significantly lower in women. Conclusions AVF remains the procedure of choice. Female sex adversely affects patency rates.
