A short right renal vein remains a challenge for renal transplant surgery, especially in the living donor. Our objective was to report on a new technique to solve this problem.
We describe our experience with the use of cryopreserved iliac artery grafts for right renal vein extension. Two renal grafts from living donors with a short right renal vein were subjected to an extension with a cryopreserved external iliac artery allograft. There were no perioperative or postoperative complications. There were also no changes in ischemia times. The renal implantation was performed easily and conveniently using our standard technique. For the first and second procedures, at 3 and 3.5 years after surgery, respectively, both vascular grafts maintain good patency, and the renal function of both recipients is optimal.
Tissue-banked cryopreserved cadaveric vessels can be a useful tool in renal transplant surgery. The use of a cryopreserved iliac artery for renal vein extension is a simple and effective new technique that can be added to the pool of surgical solutions for a short renal vein in living-donor kidney transplantation. To our knowledge, this is the first time that the use of such grafts for this purpose has been described.
短右肾静脉仍然是肾移植手术的一个挑战，特别是在活体供者中。我们的目的是报告一种解决这个问题的新技术。
我们描述了使用冷冻保存髂动脉移植物来延长右肾静脉的经验。对 2 例来自活体供者的右肾静脉较短的肾移植进行了冷冻保存的髂外动脉同种异体移植延长术。无围手术期或术后并发症。缺血时间也没有变化。使用我们的标准技术，很容易且方便地进行肾植入。在第一次和第二次手术之后，分别在术后 3 年和 3.5 年，两个血管移植物均保持良好的通畅，两个受者的肾功能均为最佳。
组织库冷冻保存的尸体血管可以成为肾移植手术的有用工具。使用冷冻保存的髂动脉进行肾静脉延长是一种简单有效的新技术，可以作为活体供者肾移植中短肾静脉的手术解决方案之一。据我们所知，这是首次描述此类移植物用于该目的。
