End-to-end arteriovenous fistula for chronic haemodialysis: 11 years' experience.

: Between January 1979 and December 1989, an end-to-end arteriovenous fistula for chronic haemodialysis was performed at the anatomical snuffbox in 140 patients with a mean age of 51 (range 14-81) years and at the wrist in 248 with a mean age of 53 (range 19-83) years. The choice of site depended on the characteristics of the vessels and on the arterial blood pressure. No operative mortality, major complications or side effects occurred. The primary median patency for the arteriovenous fistula at the anatomical snuffbox was 36 months with a patency rate of 77.3% at 1 year, 36.3% at 5 years and 18.9% at 10 years. For the arteriovenous fistula at the wrist the median patency was 64 months and the patency rate 75.5% at 1 year, 54.5% at 5 years and 30.7% at 10 years. The higher incidence of thromboses in the patients with a fistula in the snuffbox may reflect an excessive enthusiasm for this technique because of initially promising results.
