Orthotopic kidney transplantation is an option when heterotopic kidney transplantation into the iliac fossa is inappropriate. We report a case of orthotopic kidney transplantation following stenting of both external iliac arteries to treat arteriosclerosis obliterans.
A 56-year-old woman on hemodialysis for end-stage kidney disease underwent living-donor kidney transplantation. Desensitization therapy was administered because of her history of sensitization by pregnancy. Stents had been placed previously in both external iliac arteries. The left kidney was removed via an oblique lumbar incision. The two graft arteries were conjoined and anastomosed to the native renal artery end-to-end. The urinary tract was reconstructed by uretero-ureterostomy with ureteral stent placement. Renal function improved promptly after surgery.
Preoperative imaging of vascular anatomy is important for successful orthotopic kidney transplantation in patients who have previously undergone stenting of both external iliac arteries for arteriosclerosis obliterans.
当在髂窝进行异位肾移植不合适时,原位肾移植是一种选择。我们报告一例在双侧髂外动脉支架置入治疗闭塞性动脉硬化后进行原位肾移植的病例。
一名因终末期肾病接受血液透析的56岁女性接受了活体供肾移植。因其有妊娠致敏史,故给予脱敏治疗。此前双侧髂外动脉已放置支架。通过斜向腰部切口切除左肾。将两根移植肾动脉连接并与自体肾动脉端端吻合。通过输尿管-输尿管吻合术并放置输尿管支架重建尿路。术后肾功能迅速改善。
对于既往因闭塞性动脉硬化而双侧髂外动脉已放置支架的患者,术前血管解剖成像对于成功进行原位肾移植很重要。
