多层螺旋CT重建技术对亲属活体肾移植供肾的综合评价

目的 探讨多层螺旋CT(MSCT)重建技术在亲体肾移植供肾评价中的应用价值.方法 2006年1月～2009年1月在北京协和医院行亲体肾移植的供肾者6名,其中男3名,女3名,平均年龄50.1岁(37～53岁);均在术前使用64排螺旋CT机进行动态扫描,用最大密度投影、曲面重建、容积再现等技术对肾血管及集合系统进行多种方法重建.对6名供者的手术资料进行随访追踪,术中结果作为对照.结果 术前MSCT检查能清晰显示6名供者的腹主动脉、双侧肾动脉、肾静脉和集合系统大小、形态、走行以及与周围结构的关系.其中5名双肾均为单支动脉供血,1名右肾见1支副肾动脉.6名供者均成功切取左肾并移植给受者.术前对供体肾MSCT检查结果与手术所见一致.结论 MSCT重建技术可对亲属活体肾移植术前供体肾脏进行综合评价,该技术具有方便、快捷及无创的优点,值得进一步推广.

Comprehensive Evaluation of Living Kidney Donors via Multislice Spiral Computed Tomography Reconstruction

Objective To evaluate the role of multislice spiral computed tomography (MSCT) reconstruction technique in evaluation of living kidney donors.Methods From January 2006 to January 2009, six living kidney donors (3 men and 3 women, mean age 50.1 years) in Peking Union Medical Hospital underwent preoperative MSCT scanning to observe renal parenchyma, renal vessels, and collecting system.The 64-slice spiral CT scan technology was used for reconstruction of renal vascular and collection system, with maximum intensity projection (MIP), curved planar reformation (CPR), and volume rendering (VR).Surgical data of the 6 cases were followed up and the results of surgery served as controls.Results Seven renal arteries, including 1 right accessory artery, appeared at MSCT.Six renal veins, renal pelvis, and ureters were observed.All of their left kidneys were surgically resected and successfully transplanted into recipients.The operational findings were consistent with MSCT findings, with the accuracy of 100%.Conclusions MSCT is an important technique for the comprehensive evaluation of living kidney donors.The technique deserves to be further applied.
