Dacron Velour Arteriovenous Fistula for Hemodialysis Access

Abstract

Dacron velour arteriovenous fistulas were created in the necks of 12 dogs. Sham dialysis was performed 3 times/wk for 1 mo. in 6 animals and for 6 mo. in an additional 6 animals. One prosthesis became infected and perigraft bleeding occurred twice. There were no false aneurysms and all prostheses remained patent. Dacron velour appears to be a satisfactory prosthetic material for use as an arteriovenous fistula for chronic hemodialysis access. The enhanced fibrous tissue adherence of Dacron velour may account for the few complications encountered.
