Comparison of autogenous fistula versus expanded polytetrafluoroethylene graft fistula for angioaccess in hemodialysis.

A hundred patients with RCAV fistulas we compared with 100 patients with expanded PTFE fistulas created during the same time period. The fistulas were analyzed to compare early and late thrombosis, life table patency, infection rate, venous hypertension, and vascular steal. There was a significantly greater incidence of early thrombosis in the RCAV fistula group.
