| Abstract: | Thirty-three bovine grafts were placed in 28 patients for vascular access for hemodialysis. The indications were lack of shunt sites and anticoagulation with Coumadin in patients without vessels suitable for construction of a primary arteriovenous fistula. All but one of the grafts were loops placed in the forearm. There were 20 complications associated with the 33 procedures. Three patients required replacement of the initial graft in the early postoperative period due to thrombosis. One additional patient required two graft replacements and eventual anticoagulation with Coumadin before a successful result was obtained. There have been no serious ischemic problems. Presently, there are 27 functional bovine grafts, and 68 per cent of these are currently used for vascular access for dialysis. Patient acceptance of the fistulas has been good. The loop bovine graft fistula in the arm is an excellent means for vascular access in the patient receiving hemodialysis. |
