Abstract

Abstract:

Objective　To seek the new classification and research methods of the left hepatic portal vein, and to provide data and reference for the digital anatomic research of the liver.　Methods　Hisense CAS was used to reconstruct the liver vessels on upper abdomen enhanced CT data in 110 cases, and the three-dimensional images of the left branch of the portal vein were accurately displayed. The morphological characteristics and distribution of the left branch of the hepatic portal vein were investigated, and then encoded and statistically analyzed.　Results　According to the characteristics of the left branch of the portal vein, it can be divided into 6 types of codes: type I in 61 cases (55.45%), type II in 29 cases (26.36%) , type III in 13 cases (11.82%), type IV in 4 cases (3.64%), type V in 2 cases (1.82%), type VI in 1 case (0.91%). Conclusions　Hisense CAS can accurately display the three-dimensional image of the hepatic portal vein, which is convenient for observing intrahepatic ducts. It provides excellent tools for digital anatomic study of hepatic portal vein branching. For large data observation, the coding method is very convenient for statistics analysis.

Key words: Hepatic portal vein, 　Branching classification, 　Digital anatomy, 　Three-dimensional, Coding
