Long-term results of arteriovenous fistulas using transposed autologous basilic vein

Background: The transposed autologous basilic vein to brachial artery arteriovenous fistula provides vascular access in the absence of adequate superficial vein. The long-term patency and complication rates of this conduit are largely unreported. Patients and methods: Seventy-four brachiobasilic fistulas were performed in 65 patients. This was a secondary or tertiary access procedure in 84 per cent of patients. Results: Of the 74 fistulas performed, 50 were successfully used for dialysis (68 per cent) and 24 (32 per cent) were never used, including 13 fistulas that failed without being used for dialysis. Of the 74 fistulas, 46 per cent failed (n = 34), 10 patients died with a functioning fistula (n = 10) and five were transplanted. The 30-day secondary patency was 73 per cent at 1 year, 53 per cent at 2 years and 43 per cent at 3 years rate was 96 per cent. Cumulative secondary patency was 73 per cent at 1 year, 53 per cent at 2 years and 43 per cent at 3 years. Nineteen (26 per cent) fistulas underwent a further 19 operative procedures. Fifty-one (69 per cent) fistulas developed complications. The most common complications were arm oedema (24 per cent), thrombosis (22 per cent) and bleeding (18 per cent). Conclusion: In high-risk patients the autologous transposed brachiobasilic fistula has equivalent patency and lower complication rates than those reported for polytetrafluoroethylene interposition grafts.
