三维(3D)可视化技术在复杂骶骨肿瘤精准手术治疗中的价值初探

The primary exploration on the value of 3D visualization technique in the precise surgery for complex sacra tumor

目的:探讨三维(3D)可视化技术在骶骨肿瘤精准手术治疗中的应用价值。方法:选取因"发现骶骨占位半月"收治入院的1例患者,遂行CT、MRI检查获得医学数字成像及通信(DICOM)原始数据,输入计算机进行重构3D立体模型。结果:3D重构模型不仅能清晰地显示骶骨肿瘤的大小,而且还能更好地反应肿瘤的解剖形态、血供与周围组织的毗邻关系,在其指导下肿瘤被完整切除,并尽可能保全周围正常器官与神经根,且整台手术时间大为减少,出血量降低。结论:3D可视化技术应用于骶骨肿瘤手术治疗,可提升骶骨肿瘤切除术的安全性,加快手术速度,提高手术的精确性,保护重要器官与神经,从而保存相应的生理功能,在脊柱外科精准手术治疗方面具有极大的应用前景。

Objective： To investigate the application value of 3 D visualization technique in the precise surgery for complex sacra tumor. Methods： A 59-year-old female patient with the sacrum occupying for half a month was enrolled in the research. And then the original data of digital imaging and communication in medicine（DICOM）, that were obtained through CT and MRI, were imported in computer to reconstruct 3 D spatial model. Results： The reconstructive model that used 3 D technique can not only clearly display the size of sacral tumor, but also reflect the anatomic morphology, the blood supply of tumor and the relationship between tumor and surrounding tissues. Under its guidance, the tumor could be completely removed, and the surrounding normal organs and nerve roots could be preserved as much as possible. Besides, the operation time was greatly decreased and the amount of bleeding was reduced. Conclusion： The application of 3 D visualization technique in the surgical treatment for sacral tumor can enhance the safety of the tumorectomy of sacral tumor, and accelerate the operation speed, and increase the accuracy of operation, and protect vital organs and nerves, thus preserve the corresponding physiological function. Therefore, it has great application prospect in the precisely surgical treatment of spinal surgery.
