摘要

目的：利用计算机辅助肝脏CT影像解读分析系统对肝内门静脉和肝静脉进行三维解读分析，观察分析门静脉和肝静脉解剖和变异。方法：收集200例行上腹部64-MSCT增强扫描并排除存在可能改变血管解剖结构的病理状态检查者。利用IQQA-Liver肝脏CT解读软件对门静脉和肝静脉进行三维定量分析、显示及分支标记，并对其解剖和变异进行分析。结果：IQQA-Liver分割及标记门静脉和肝静脉耗时短，且个体化门静脉和肝静脉3D定量模型形态逼真，立体感强，真实反映了门静脉和肝静脉的解剖结构和变异。正常门静脉解剖71.5%（143/200），解剖变异28.5%（57/200）。148例（74%）肝中、肝左静脉合并汇入下腔静脉。大于3 mm右后下肝静脉的显示率为36.5%（73/200）。大于5 mm的引流SⅧ段至中肝静脉的属支静脉的显示率为30%（60/200）。结论：肝内门静脉和肝静脉变异并不少见。IQQA-Liver三维定量分析及显示可真实反映门静脉和肝静脉的形态结构，为肝脏的虚拟手术设计提供了可实时交互的血管解剖变异各种3D模型，为上腹部脏器介入插管治疗提供了活体解剖学数据。

Abstract

Objective: To investigate 3D interpretation and analyse the data of anatomical variation of hepatic vessels using enhanced CT on 64-MSCT. Methods: 200 cases performed on 64-MSCT were examined. 3D display and marking of the hepatic vessels and branches were performed using IQQA-Liver software. The anatomic variation was evaluated. Results: The adopted method of vessel segmentation, marking and analysis was time-efficient, and resulted in individualized real-time interactive 3D vascular models representing true structures verified on original 2D DICOM images. Normal type of portal vein accounted for 71.5%(143/200), and the variants 28.5%(57/200). The left hepatic vein shared a common trunk with the middle one in 148 subjects(74%). Visualization rate of right inferior hepatic vein with diameter larger than 3 mm was 36.5%(73/200). The presence rate of a significant segment Ⅷ vein(>5 mm) draining to MHV was 30%(60/200). Conclusion: Variation of the hepatic vessels is not rare. The individualized 3D vascular models from CT data analysis in this study represented the anatomic variations of hepatic vessels well, and provided sufficient real-time interaction to various types of anatomical variations for surgery and interventional planning.
