Abstract: Objective To explore the application value of Revolution CT combining three?dimensional visualization technique in the precision resection of hepatic alveolar echinococcosis. Methods Totally 12 patients with surgical treatment and pathologically confirmed hepatic alveolar echinococcosis in Qinghai Provincial People’s Hospital were retrospectively analyzed. All the patients underwent the Revolution CT plain and enhancement scan before surgery, and the 0.625 millimeter scan data were obtained. The DICOM format data were imported into MI?3DVS for three?dimensional reconstruction, simulated cutting, volume measurement, and surgical planning. Results  The data of 12 patients were reconstructed successfully, and the sizes and locations of the lesions as well as the hepatic vascular systems were clearly displayed. The liver volume, hydatid volume, simulated resection volume, and residual liver ratio were measured accurately. The average whole liver volume and the lesion volume of the 11 surgical treated patients were (2 429.8 ± 335.9) mL and (919.6 ± 262.8) mL respectively. The average actually removed volume was highly associated with the average simulated resection volume (r = 0.979, P < 0.01). Conclusion Revolution CT combining three?dimensional visualization technique can achieve accurate diagnosis as well as optimal surgical planning before operation, which is of great value for the precision resection of difficult hepatic alveolar echinococcosis.

摘要: 目的 探究Revolution CT结合三维可视化技术在指导肝棘球蚴病精准切除术中的应用价值。方法 回顾性分析青海省人民医院12例经手术治疗的多房棘球蚴病患者临床资料,所有患者术前均接受Revolution CT上腹平扫+增强检查,将DICOM格式的0.625 mm扫描数据导入人体三维可视化软件(MI?3DVS)进行三维重建、模拟切割、体积测量并制定手术规划。结果 12例患者均完成了三维可视化模型重建,棘球蚴病病灶大小、所在肝段及肝内血管系统均显示清晰,并准确测得全肝体积、棘球蚴病病灶体积、模拟切除体积和残肝比。11例手术患者平均全肝体积为(2 429.8 ± 335.9) mL,平均棘球蚴病病灶体积为(919.6 ± 262.8) mL,实际切除病灶体积与模拟切除病灶体积具有高度相关性(r = 0.979,P < 0.01)。结论 Revolution CT结合三维可视化技术能实现术前准确诊断并制定最佳手术规划,对指导难度较大的肝多房棘球蚴病精准切除术具有重要价值。
