摘　　要：目的研究数字医学技术在临床活体肾移植中的应用价值。方法收集2009年1月2010年12月在广东省第二人民医院器官移植科进行的5例亲属活体肾移植的16排螺旋CT扫描数据。利用医学图像三维可视化系统重建出供、受体的三维模型,将重建后的活体肾移植供受体三维模型导入到FreeForm Modeling System,根据各病例特点,制定出最合理的个体化手术方案,并利用仿真手术器械进行仿真手术,验证手术的合理性,术中可与三维重建及仿真手术结果比较,评价其价值。结果重建的肾脏及其血管模型清晰、立体感强,可三维地辨认肾血管及血管变异情况,依据这些病例特点,合理制定了个体化手术方案,在仿真手术中确定了最合理的手术方案;术中发现与三维重建情况完全吻合,并依据术前仿真结果 ,顺利完成了临床活体肾移植手术,术后患者恢复良好,未出现明显并发症。结论术前三维重建及仿真手术优化了活体肾移植的手术方式,提高了手术成功率。Objective To study the application of digitized three-dimensional （3D） image reconstruction in living-related kidney transplantation. Methods The image data of 16-slice spiral CT in 5 cases of living-related kidney transplantation were collected to reconstruct the 3D model of the donor and recipient, which were then imported in the FreeForm Modeling System. The optimal surgical approach for each individual case was planned and simulated for verification. During the actual surgeries, the surgical findings were compared against the reconstructed model and the results of simulated surgery. Results The 3D model clearly displayed the anatomy of the kidney and the variation of the related vessels. The optimal surgical approaches were planned through the simulated surgery. The anatomy of the kidney and the related vessels found in the actual surgeries were consistent with that displayed by the reconstructed 3D model. All the operations were completed successfully according to the surgical plan, and the patients recovered uneventfully without obvious complications. Conclusion Three-dimensional reconstruction and simulated surgery allow optimization of the surgical approaches of living-related kidney transplantation to ensure successful operation and minimize the surgical risks
