Objective To describe the CT features of the right hepatic portal vein and hepatic vein by upper abdominal angiography with 256-slice spiral CT, and to explore the anatomical relationship and the redefinition of liver segmentation, so as to explore its clinical significance. Methods One hundred cases who were randomly collected were examined with plain CT scanning and three-phase enhanced CT scanning. The distribution of right hepatic portal vein and the branches, hepatic vein and the branches after 3D reconstruction were observed, and the relevant data were statistically analyzed. Results The distribution of portal vein: S5 segment could be divided into 4 types. There were 66 cases of A type, 10 cases of B type, 8 cases of C type, and 16 cases of D type. S6 segment could be divided into 6 types, A type 56 cases, B type 15 cases, C type 4 cases, D type 17 cases, E type 4 cases, F type 4 cases . S7 segment could be divided into 3 types, A type 73 cases, B type 23 cases, C type 4 cases. S8 segment could be divided into 5 types, A type 67 cases, B type 3 cases, C type 2 cases, D type 8 cases, E type 20 cases. The distribution of hepatic vein: 45 cases of LHV, MHV and RHV were imported into IVC respectively. Fifty-five cases of LHV and MHV formed common trunk and were imported into IVC. IRHV was found in 36 cases, 11 cases of RHV were small with compensatory blood supply to the right liver by developed MHV. The main MHV trunk was located above the main bifurcation of the portal vein in 15 cases, and the MHV was located right of the Rex-Cantlie line in 41 cases. In this paper, the spatial position relationship between hepatic vein and portal vein was divided into four types. Type A has the most (accounting for 64%) and type D has the least (accounting for 3%). Conclusions The anatomical features of the hepatic vein and portal vein in the right part of the liver is complex and diverse. The spatial distribution of hepatic vein and portal vein also change when the main portal vein is mutated. It has imaging guiding significance for the smooth implementation of individualized liver surgery.
