CT血管造影活体供肾术前检查的意义

CT angiography in the meaning of living donor kidney preoperative examination

目的通过CT肾血管造影在肾移植术前精确测量及评价供体肾脏大小、肾动脉、肾静脉长度、管径以及肾脏排泄功能等所需数据;并通过与手术结果对比,证明此检查的必要性。方法回顾性分析100例活体供肾者CT肾血管造影检查。结果本组100例活体供肾者,共200组动、静脉(左右分别为一组):126例为正常单支肾动脉供血;52例双支动脉供血;22例肾动脉肾门前分支,其开口处分支均大于1.5 cm,18例右肾双支静脉;5例左肾双支静脉并副肾走行于腹主动脉后方汇入下腔静脉;2例肾盂输尿管重复畸形。结论经CT肾血管造影后所得数据,给予肾移植手术术前准备、供体肾脏选择以及预后评估很大数据支持,并通过对比手术记录,CT肾血管造影诊断符合率为98%,因此CT肾血管造影有必要作为肾移植术前供体的常规检查。

Objective Through CT renal angiography in renal transplantation preoperative accurate measurement and evaluation of donor kidneysize,renal artery,renal vein length,diameter,and the required data such as renal excretion function;And compared with surgical results,provedthe necessity of this check.Methods Retrospective analysis of100cases of living donor kidney CT renal angiography.Results This group of100cases of living donor kidney,a total of200groups of arteries and veins(left and right sides of a group)respectively:126cases of normal single renalartery blood supply;52cases of double branch artery;22cases of renal artery in front of the branch,the branch opening were greater than1.5cm,18cases of double right kidney vein;5cases of left renal vein and adrenal gland line in abdominal aorta back into the inferior vena cava;2cases of renalpelvis ureter repeat deformity.Conclusion Data obtained after CT renal angiography for kidney transplant surgery preoperative preparation,choiceof donor kidney and prognosis assessment of large data,and by comparing the operation records,CT of renal angiography diagnosis coincidence rateis98%,so CT renal angiography is necessary as a routine inspection of preoperative donor renal transplantation.
