The use of elderly deceased donors requires refining criteria for both the donor and the recipient. This report attempted to identify parameters susceptible to further improvement. This retrospective multicenter study analyzed the outcomes of kidney recipients from 15 consecutive elderly deceased donors in the south French region (IR9). Donors were 65 to 74 years old. Mean creatinine clearance was 80 mL/min/1.73 m(2). The donor risk factors for allograft dysfunction were stroke, hypertension, cardiovascular disease, cardiac death, smoking, arrhythmia, and diabetes. The recipients were 35 to 70 years old. The median cold ischemia time was 24 hours. Four patients (16%) suffered delayed graft function (DGF). Three recipients (12%) died within the first 2 months after transplantation. The postoperative complications (29%) were 2 renal artery thromboses, 4 renal artery stenoses, and 1 toe ischemia. Two years after transplantation, their mean serum creatinine was 157 micromol/L. The patient and graft survivals were 88% and 70%, respectively. These results seemed worse than those reported in the literature, but it was a small cohort and a new experience. DGF is probably linked to improvable management to reduce cold ischemia time. The elevated rate of surgical complications might be related to a lack of experience in donor and recipient evaluations. Kidney transplantation from elderly donors requires an efficient organization and an accurate evaluation of both donor renal function and recipient cardiovascular state.
使用老年已故供体需要完善供体和受体的标准。本报告试图确定易于进一步改进的参数。这项回顾性多中心研究分析了法国南部地区(IR9)连续15例老年已故供体的肾移植受者的结局。供体年龄在65至74岁之间。平均肌酐清除率为80 mL/min/1.73 m²。移植肾功能障碍的供体危险因素包括中风、高血压、心血管疾病、心源性死亡、吸烟、心律失常和糖尿病。受体年龄在35至70岁之间。中位冷缺血时间为24小时。4例患者(16%)发生移植肾功能延迟恢复(DGF)。3例受体(12%)在移植后前2个月内死亡。术后并发症发生率为29%,包括2例肾动脉血栓形成、4例肾动脉狭窄和1例足趾缺血。移植后两年,他们的平均血清肌酐为157 μmol/L。患者和移植物存活率分别为88%和70%。这些结果似乎比文献报道的要差,但这是一个小队列且是新的经验。DGF可能与可改进的管理措施有关,以减少冷缺血时间。手术并发症发生率升高可能与供体和受体评估经验不足有关。老年供体肾移植需要高效的组织以及对供体肾功能和受体心血管状态的准确评估。
