Two cases of renal allograft artery stenosis secondary to circumferential malalignment of the anastomotic site with the recipient external iliac artery are presented. One stenosis was temporary with apparent resolvement by dilatation of the allograft artery; the other was permanent and required operative correction by patch angioplasty. Circumferential malalignment of the arterial anastomotic site, when the renal artery is placed end to side into the recipient external iliac artery, is proposed as an etiologic mechanism for both temporary and permanent renal allograft artery stenosis. Careful attention to the final position of the graft in the retroperitoneum when the site for arterial anastomosis is chosen will prevent this complication of human renal allotransplantation.
本文报告两例同种异体肾移植动脉狭窄病例，其病因是吻合部位与受者髂外动脉发生周向不对位。其中一例狭窄为暂时性，经移植肾动脉扩张后明显缓解；另一例为永久性，需行补片血管成形术进行手术矫正。当肾动脉端侧吻合至受者髂外动脉时，动脉吻合部位的周向不对位被认为是导致暂时性和永久性同种异体肾移植动脉狭窄的病因机制。在选择动脉吻合部位时，仔细关注移植物在腹膜后的最终位置，可预防人类肾移植的这一并发症。
