【摘要】：目的探讨三维重建及3D打印技术在腹膜后肿瘤术前评估中的应用价值。方法回顾性分析2011年3月至2015年9月厦门大学附属成功医院收治的50例腹膜后肿瘤病人的临床资料,应用人体器官三维建模软件将病人的CT二维图像重建成三维可视化图像,使用人体器官模型3D打印设备,用两色热塑性塑料打印实物模型,通过观察肿瘤与腹腔器官、腹部大血管之间的关系进行术前评估并制定手术方案。实施手术,术中比较重建结果与实际的区别。结果 50例病人均成功完成三维重建,其中10例病人完成3D打印,三维重建结果及3D打印模型能够立体、清晰和实物化的显示肿瘤解剖学位置及与周围器官、血管的毗邻关系,与术中实际情况大致相符。50例病人均顺利施行手术,术中无死亡。结论三维重建及3D打印技术能够对腹膜后肿瘤术前进行精准评估,对指导手术具有一定的应用价值。
[Abstract]:Objective to evaluate the value of 3D reconstruction and 3D printing in preoperative evaluation of retroperitoneal tumor. Methods the clinical data of 50 patients with retroperitoneal tumor admitted from March 2011 to September 2015 were retrospectively analyzed. The CT 2D images of patients were reconstructed into 3D visualized images by using 3D modeling software of human organs. The 3D printing equipment of human organ model and the object model were printed with two-color thermoplastic. The tumor and abdominal organs were observed. The relationship between the great vessels of abdomen was evaluated before operation and the operative plan was worked out. The results of the operation were compared with the actual results. Results all the 50 patients had completed 3D reconstruction successfully, and 10 of them had completed 3D printing. The results of 3D reconstruction and 3D printing model can show the anatomical position of tumor and the adjacent relationship with the surrounding organs and blood vessels in a stereoscopic, clear and physical manner. The results are roughly consistent with the actual situation during the operation. 50 patients were successfully operated on. Conclusion 3D reconstruction and 3D printing can accurately evaluate retroperitoneal tumor before operation and have certain application value in guiding operation.
