Our main aim was to evaluate the value of medical image three-dimensional visualization system (MI-3DVS) in pancreaticoduodenctomy patients with hepatic artery variance.
114 patients who had undergone pancreatoduodenectomy were retrospectively summarized and analyzed. Clinical data of 64-slice multidetector CT angiography (64-MDCTA) scanning was introduced into MI-3DVS for procedural segmentation, registration and 3-dimensional (3D) reconstruction. The findings were compared with those found during the operation and by postoperative digital subtraction angiography (DSA) of coeliac artery.
The 3D model demonstrated the origination and bifurcations of blood vessels, and the relationships among neoplasms, organs and blood vessels efficiently. About (14/114 cases, 12.3%) had variant. The sensitivity, specificity and accuracy of MI-3DVS in variant hepatic artery diagnosis were 100%. It assisted in preoperative procedural planning that was consistent with intraoperative findings.
MI-3DVS can be applied for accurate diagnosis of hepatic artery variance. It also provides detailed preoperative guidance for individualized procedural planning.
我们的主要目的是评估医学影像三维可视化系统（MI-3DVS）在肝动脉变异的胰十二指肠切除术患者中的价值。
回顾性总结并分析114例行胰十二指肠切除术的患者。将64层螺旋CT血管造影（64-MDCTA）扫描的临床数据导入MI-3DVS进行程序分割、配准和三维（3D）重建。将结果与手术中及术后腹腔动脉数字减影血管造影（DSA）的结果进行比较。
3D模型有效地展示了血管的起源和分支，以及肿瘤、器官和血管之间的关系。约（14/114例，12.3%）存在变异。MI-3DVS在变异肝动脉诊断中的敏感性、特异性和准确性均为100%。它有助于术前程序规划，且与术中发现一致。
MI-3DVS可用于准确诊断肝动脉变异。它还为个体化程序规划提供详细的术前指导。
