亲属活体肾移植供肾副肾动脉的处理及临床疗效分析

Analysis of the management and clinical effect of accessory renal artery in the living-related donor renal transplantation

目的探讨亲属活体肾移植供肾副肾动脉的处理及其临床疗效。方法回顾性分析277例亲属活体肾移植供、受者的临床资料。根据术前CT血管造影(CTA)结果选择供肾,并在术中处理供肾副肾动脉。总结供者术中情况,受者术中处理、术后并发症情况及预后情况。结果 277例肾移植中,术前CTA检查发现83例供者存在副肾动脉,CTA判断准确率为95%。获取有副肾动脉的供肾58例,25例供肾副肾动脉经过血管修整重建吻合后,除1例与腹壁下动脉吻合者在关腹时发现吻合口血栓形成外,其余24例均吻合成功,血流充盈良好。术后均未发生出血、移植肾栓塞、输尿管坏死、尿瘘等并发症。移植受者和移植肾的1年存活率分别为94%和91%。单支肾动脉供肾与有副肾动脉供肾其受者的临床疗效比较,差异无统计学意义(P>0.05)。结论选择合适供肾,经血管修整重建吻合移植肾副肾动脉,可获得良好移植效果。

Objective To investigate the management and clinical effect of accessory renal artery in livingrelated donor renal transplantation. Methods Clinical data of 277 donors and recipients undergoing living-related donor renal transplantation were retrospectively analyzed. According to the results of preoperative CT angiography(CTA), the donor kidney was selected and the accessory renal artery of the renal graft was treated intraoperatively. Intraoperative status of the donors, and intraoperative management, postoperative complications, clinical prognosis of the recipients were summarized. Results Among 277 cases of renal transplantation, accessory renal arteries were detected in 83 donors by preoperative CTA examination with an accuracy rate of 95%. Fifty-eight donor kidneys with accessory renal arteries were obtained. Twenty-five donor kidneys with accessory renal arteries were reconstructed and anastomized by vascular repairing. Among them, 1 patient presented with anastomotic thrombosis during abdominal closure, whereas the other 24 cases were successfully anastomized with excellent blood flow. No complications, such as hemorrhage, renal graft embolism, ureteral necrosis and urinary fistula, occurred after renal transplantation. The 1-year survival rates of the recipients and renal grafts were 94% and 91%. The clinical efficacy did not significantly differ between the recipients with single renal artery and their counterparts with accessory renal artery(P>0.05). Conclusions It can be obtained good clinical efficacy of renal transplantation by selecting a suitable donor kidney and reconstructing and anastomizing the accessory renal artery of the renal graft through vascular repair.
