MSCT在活体肾移植供体术前评估中的价值

The value of multi-slice helical CT in preoperative evaluation of living renal donor

目的:评价MSCT在活体肾移植供体术前评估中的价值。方法:采用MSCT对58例活体肾移植供体行平扫、肾动脉期、肾静脉期及排泄期扫描,原始图像传入AW4.2工作站,运用VR、MIP、MPR、CPR等多种后处理技术综合分析评估肾动脉、肾静脉、肾实质及集合系统,并与30例手术结果相对照。结果:所有供体均能清晰显示肾动、静脉主干及分支,副肾动脉,肾动脉过早分支,肾动静脉变异,集尿系统情况,并与手术结果相符合。结论:MSCT能清晰显示供肾的血管结构、肾实质及输尿管情况,能够作为肾移植供体术前检查最重要的影像学方法。

Objective:To investigate the value of multi-slice spiral CT in preoperative evaluation of living renal donor.Methods:58 living renal donors underwent multiphase(plain scan,arterial phase,venous and excretory phase) MSCT scan before operation,all the image information were send to GE workstation AW4.2,Reconstruction and processing included volume rendering(VR),maximum intensity projection(MIP),multiple planar reconstruction(MPR),curved planar reconstruction(CPR).30 findings of MSCT were compared with intraoperative findings so as to investigate the value in assessing renal vascular,urinary tract and lesion of renal parenchyma.Results:MSCT angiography is in accordance with intraoperative findings in demonstrating the anatomy of renal arteries and renal vein trunks,accessory arteries,early branching of renal artery,the variations on renal arteries and veins.CT urography also demonstrates the urinary tract in good agreement with intraoperative findings.Which facilitate intraoperative ligation and deduce relevant complications.Conclusion:The MSCT multiphase scanning play a very important role in the assessing renal donor,through which we can obtain the details of vascular,urinary tract and lesion of renal parenchyma before kidney transplantation.
