The common trunks of the intermediate and left hepatic veins were studied by anatomical dissection of 40 adult human cadaver livers. The common trunk of the intermediate and left hepatic veins showed 5 types of termination of intermediate and left hepatic vv.: classification of Nakamura. In types A, B, C, and D, the intermediate and left hepatic veins showed a common trunk in 31/40 or 77.5% of cases that flowed into the inferior vena cava. Whereas in type A termination ( 3/40 cases) common trunks of 1 cm or over which do not receive a branch in the last cm, in type B terminations ( 11/40 cases) the trunk received two branches less than 1 cm from the IVC, short trunks, or trunks of over 1 cm associated with one branch, in type C terminations (12/40 cases), the common trunks having three branches less than 1 cm from the IVC and in type D terminations (5/40 cases),the trunk received four branches. The diameter of the common trunk was 16.09 3.3mm and its length, 7.52.3mm. In type E terminations (9/40 or 22.5% of cases), the intermediate and left hepatic veins ended separately in the inferior vena cava. The diameter of the intermediate and left hepatic veins in 40 cases was 8.681.51 mm and 8.61.22 mm, respectively.
