Vascular access for chronic hemodialysis using modified bovine arterial graft arteriovenous fistula

Modified bovine arterial graft arteriovenous fistulas were used for access to the circulation for hemodialysis in thirty-six patients whose forearm vessels were unsuitable for Brescia-Cimino fistulas. Twenty-seven of thirty-one thigh fistulas and three of five forearm fistulas are still functioning well. Most of the complications were minor and may be preventable. Thigh heterografts provided excellent blood flow for dialysis and have been the most successful alternative for patients who have repeated shunt or fistula failures.
