Autologous saphenous vein grafts are occasionally used in renal transplant recipients, particularly in living donors with short donor vessels or after donor vessel injury during allograft procurement. Autologous saphenous vein graft aneurysm formation is described as a late complication following the use of this conduit in renal transplant. We report a case of a 45-year-old woman who developed an autologous saphenous vein graft aneurysm 21 years after her living donor transplant, which was successfully managed with explantation of the graft, cold perfusion ex situ, and resection of the aneurysm, which was followed by reconstruction using deceased donor iliac vessels. The graft was then successfully reimplanted. Based on this experience and after a review of the literature related to autologous saphenous vein graft aneurysms in renal transplant, we recommend that surveillance for this particular complication should be considered no later than 10 years after implant of an autologous saphenous vein graft when used as an arterial conduit.
自体大隐静脉移植物偶尔用于肾移植受者，特别是在有短供体血管的活体供者或同种异体肾获取过程中供体血管损伤后。自体大隐静脉移植物动脉瘤形成是该移植物在肾移植后使用的晚期并发症。我们报告了一例 45 岁女性，在活体供者移植后 21 年发生自体大隐静脉移植物动脉瘤，通过移植物切除、体外低温灌注和动脉瘤切除成功治疗，然后使用已故供体髂血管进行重建。然后成功地重新植入移植物。根据这一经验，并对与肾移植中自体大隐静脉移植物动脉瘤相关的文献进行回顾，我们建议在使用自体大隐静脉作为动脉移植物后，最迟应在 10 年内对这种特殊并发症进行监测。
