目的 借助可视化3D影像认识肝脐裂静脉(Umbilical fissure vein，UFV)的解剖。 方法 回顾性分析2017年6月-2018年12月期间60例有肝胆相关疾病患者的影像资料，在可视化3D影像下分析肝脐裂静脉的发生率、脐裂静脉的走形及汇入方式、脐裂静脉与Ⅳb段肝静脉的关系。 结果 55例病人发现了UFV静脉，发生率91.6%。UFV发自肝左静脉的有49例，发生率89.1%（49/55）；发自肝中静脉的4例，发生率7.3%（4/55）；发自肝中肝左共干的2例，发生率3.6%（3/55），17例发现肝Ⅳb段汇入UFV，发生率为30.9%（17/55）。 结论 可视化3D影像对于术前辨明UFV及其走行有很大的帮助，有助于避免手术中的副损伤。
Abstract
Objective To investigate the ramification of the umbilical fissure vein based on the visual three-dimension imaging. Methods A total of 60 patients diagnosed with hepatobiliary diseases who had been received CT angiography scanning from Jun.2017 to Dec.2018 were observed and analyzed retrospectively. The incident rate, the form and afflux way of the umbilical fissure vein and the relationship between the umbilical fissure vein and the IVb hepatic vein were analyzed based on the visual 3D imaging. Results UFV was observed in 55 patients (incidence rate: 91.6%), while there were 49 cases arising from left hepatic vein (LHV) in the 55 cases of UFV (incidence rate: 89.1%), 4 cases arising from the middle hepatic vein(MHV) (incidence rate: 7.3%), 2 cases from the common trunk of the LHV and MHV(3.6%). There was 17 cases occurring segment IVb hepatic vein afflux into UFV. Conclusions There is great help for the visual 3D imaging to distinguish UFV and make surgery planning preoperative, which can avoid operative side injuries.
