Axillobifemoral bypass is a well-established surgical procedure performed in conditions that preclude direct arterial reconstruction due to aortic sepsis, aortoenteric fistula, or other hostile abdominal pathology or prohibitive surgical risk. The choice of prosthetic graft used is either knitted Dacron® or polytetrafluoroethylene, with equally good results. Although externally supported grafts reportedly yielded improvement in primary patency compared to historical controls, no consensus exists as to which demonstrates superiority over the other despite several retrospective studies. Complications are usually limited to the perioperative period, although late anastomotic disruption, graft thrombosis, axillary thromboembolism, pseudoaneurysm formation due to seat belt trauma, and hemorrhage or graft rupture have all been described. In addition to the above complications responsible for graft failure, perigraft infection, intimal hyperplasia, poor distal runoff, anastomotic fibrosis, and comorbid conditions may contribute to graft failure. We describe an unusual late complication of an axillobifemoral bypass graft whereby an organized thrombus within the layers of the bypass graft led to luminal compromise and, hence, attenuation of flow and resultant “failing graft.”
