目的:探讨磁共振肾血管显像(MRA)在亲属活体肾移植供体术前综合评估中的临床应用价值。方法:回顾性分析60例供体术前MRA资料,并与术中肾血管解剖发现作对比,以后者作为诊断的金标准。结果:60例供体术中证实单支肾动脉54例,6例存在副肾动脉,其中2例术前MRA曾诊断供肾单支动脉。MRA供肾血管有效阳性预测值为96.6%,假阴性率为33%,多支血管敏感性为66%。无一例供体在MRA检查中发生副反应而放弃检查。结论:亲属活体肾移植供体术前应常规进行MRA作血管三维成像检查。MRA术前能够充分了解供肾体积、引流系统及实质有无畸形,帮助供体选择,确保取肾术绝对安全,提高取肾质量。
Objective: To investigate the clinical value of magnetic resonance renal angiography (MRA) in the comprehensive evaluation of donor living donor renal transplant recipients. Methods: The MRA data of 60 donors were retrospectively analyzed and compared with the findings of intraoperative renal vascular anatomy. The latter was used as the gold standard for diagnosis. Results: Fifty-four cases of single renal artery were confirmed in 60 cases of donor surgery. There were 6 cases of accessory renal artery. Among them, 2 cases had preoperative MRA diagnosis of single renal artery. MRA positive predictive value for renal blood vessels was 96.6%, false negative rate was 33%, multivessel sensitivity was 66%. None of the donors had a side reaction in the MRA test and gave up the test. Conclusion: MRA should be routinely performed for three-dimensional imaging of blood vessels before living donor renal transplantation. MRA before surgery to fully understand the volume of the kidneys, drainage system and the real deformity, to help the donor selection, to ensure absolutely absolute kidney surgery, improve kidney quality.
