Distal emboli as an unusual late complication of a thrombosed arteriovenous hemodialysis graft.

Abstract

The creation of an arteriovenous fistula for long-term hemodialysis access is one of the most commonly performed procedures in vascular and transplantation surgery. Prosthetic conduits are frequently prone to failure within their first year of construction, and after one or two revisions, they are left in their thrombosed state as permanent subcutaneous foreign bodies in the extremities. Conventional teaching has regarded these chronically thrombosed grafts to have a benign natural history, and their removal has been considered unnecessary. We describe an unusual late complication of distal thromboemboli from a chronically occluded arteriovenous graft that was implanted 10 years before and appeared as acute hand ischemia.
