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.
接受冷冻保存的尸体动脉同种异体移植（CCAA）进行血管重建的患者由于同种异体移植失败的风险需要终身监测。这些移植物报道的长期并发症包括血栓形成、吻合口假性动脉瘤和移植物破裂。我们描述了一例病例，其中一个CCAA在先前结扎的分支血管部位出现了非吻合口假性动脉瘤，并使用覆膜支架移植物进行了修复。该病例表明，CCAA分支的自发性破裂是使用这些移植物时可能发生的晚期并发症，并且血管内方法是一种修复选择。
