Abstract

Patients who have undergone revascularization with a cryopreserved cadaveric arterial allograft (CCAA) require lifelong surveillance because of the risk of allograft failure. The reported long-term complications of these grafts include thrombosis, anastomotic pseudoaneurysm, and graft disruption. We have described a case in which a CCAA developed a nonanastomotic pseudoaneurysm at the site of a previously ligated branch vessel and was repaired using a covered stent graft. This case demonstrates that spontaneous rupture of CCAA branches is a late complication that can occur when using these grafts and that endovascular methods are an option for repair.
