BACKGROUND: Our main aim was to evaluate the value of medical image three-dimensional visualization system (MI-3DVS) in pancreaticoduodenctomy patients with hepatic artery variance. METHODS: 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. RESULTS: 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. CONCLUSIONS: MI-3DVS can be applied for accurate diagnosis of hepatic artery variance. It also provides detailed preoperative guidance for individualized procedural planning.
