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.
