ABSTRACT
Background: The main goal of this research was to clarify the existence of a paracaval area as the most common location for liver malignancies. Material and Methods: On 30 cadaveric human liver specimens of adults the injection-corrosive method was used. Portal vein segmentation, and then types of segment 9 subdivision were determined in 27 portobiliary casts of proper quality with the help of a magnifying lens. Results: The results confirmed four different types: type I only with 9d portal branches in 3.71%; type II with 9c and 9d portal branches and biliary ducts in 14.81%; type III with 9b, 9c, and 9d portal branches and only 9b and 9c biliary ducts also in 14.81%; and type IV with portal branches and biliary ducts of all subsegments in 66.67% of cases. Conclusion: This investigation confirms the complete presence of all three subsegments in 66.67% and partially in the remaining 33.33% of cases.
