基于3D可视化技术的肾脏肿瘤精准手术

Renal Tumor Precise Surgery Based on 3D Visualization Technology

目的探讨3D可视化技术在肾脏肿瘤精准手术治疗中的意义。方法对一例50岁的男性患者行B超检查发现左侧肾脏有占位性病变,遂行多排CT平扫加增强检查获得CT的DICOM数据,输入计算机进行立体模拟建模。结果 3D重建模型可以清晰地显示肿瘤周围的解剖结构,特别是周围血供。在它的指导下,肿瘤被完整切除,并尽可能保全正常的肾组织,且整台手术时间大为减少。结论 3D可视化技术应用于肾脏肿瘤的治疗,能清晰显示其解剖结构,辨识肿瘤毗邻血管,在避免遗漏肿瘤的同时,更有效地辅助术前规划,增加了肾脏的复杂手术的安全性、加快了手术速度,提高了手术的精确性。在肾脏肿瘤外科精准手术治疗方面具有极大的应用前景。

Objective We performed this study aim to explore the signifcance of 3D visualization technique in the treatment of renal tumor. methods A 50-year-old male patient who was diagnosed with left renal lesion by ultrasound examination in local hospital was examined by multi-row CT to obtain DICOM data. Three-dimensional model was reconstructed after the raw data was input into the computer. Results 3D reconstruction model clearly displayed the anatomical structure around the tumor, especially the peripheral blood supply. Under the guidance of 3D visualization technique, the tumor was completely resected while the normal kidney tissue was preserved as much as possible, and the operation time was greatly reduced. Conclusion The 3D visualization technology applied to renal tumor surgery can clearly display the anatomic structure and adjacent vessels of tumor. It can assist the preoperative diagnosis of complex kidney surgery so as to enhance the security, reduce the operation time, and improve operation accuracy. Therefore, this technique can be applied for surgical operation of renal carcinoma with great prospect.
