目的:探讨三维可视化技术在复杂骨与软组织肿瘤外科手术治疗中的临床应用价值。方法:回顾性研究。纳入2019年4—12月中国科学技术大学附属第一医院(西区)骨科11例复杂骨与软组织肿瘤患者的临床资料，其中男5例、女6例，年龄16～67(52.6±15.9)岁。11例患者术前均行CT常规二维扫描及三维可视化技术重建，于重建模型上观察肿瘤与周围组织尤其是血管的关系、评估肿瘤的可切除性及安全切缘、指导制定手术方案并模拟手术操作；对比常规CT二维扫描与三维可视化重建影像的观察结果，并于肿瘤切除手术中观察验证术前三维可视化重建影像评估的准确性。结果:本组11例患者CT二维扫描图像经三维可视化技术重建后，可清晰显示肿瘤形态、大小及其与周围组织的关系。对比CT二维扫描影像，三维可视化技术在手术策略精准制订和指导手术操作方面更具有优势。除1例因腹腔转移未予手术治疗外，余10例患者经三维可视化技术评估后均顺利完成安全边界外肿瘤完整切除术，无血管损伤并发症发生，术中探查结果与术前三维可视化模型的判断基本一致。结论:在复杂骨与软组织肿瘤术前应用三维可视化技术可以提高术前评估的准确性，指导个体化精准手术方案的制订，协助确定肿瘤外科边界并完整切除肿瘤，使患者获得更好的疗效。“,”Objective:To explore the clinical application value of three-dimensional visualization technology in the surgical treatment of bone and soft tissue tumors.Methods:The retrospective study was conducted. The clinical data of 11 patients (including 5 males and 6 females, aged 16-67 (52.6 ± 15.9) years old) with bone and soft tissue tumors in the First Affiliated Hospital of the University of Science and Technology of China (Western District) from April to December 2019 were retrospectively analyzed. All 11 patients underwent conventional two-dimensional CT scan and three-dimensional visualization technology reconstruction before operation. The relationship between tumor and surrounding tissues, especially blood vessels, was observed on the reconstructed model. The tumor's resectability and safe margins were evaluated, and the surgical plan was formulated and simulated. The observation results of conventional two-dimensional CT scan and three-dimensional visualization reconstruction image were compared during surgical operation and tumor resection to verify the accuracy of image evaluation of preoperative three-dimensional visualization reconstruction.Results:The two-dimensional CT images of 11 patients were reconstructed by three-dimensional visualization technology, which clearly showed the tumor shape, size, and its relationship with surrounding tissues. Compared with two-dimensional CT scan images, three-dimensional visualization technology has more advantages in accurately formulating surgical strategies and guiding surgical operations. Except for one patient who did not receive surgical treatment due to abdominal metastasis, the remaining 10 patients successfully underwent complete resection of the tumor outside the safe boundary after the evaluation of the three-dimensional visualization technology, and no vascular injury complications occurred. The results of intraoperative exploration and preoperative three-dimensional visualization were basically the same.Conclusions:The preoperative application of three-dimensional visualization technology in bone and soft tissue tumors can improve the accuracy of preoperative evaluation, guide the formulation of individualized and precise surgical plans, and assist in determining the surgical boundary of and completely remove the tumor, so that patients can obtain better curative effects.
