Intrahepatic Branching Pattern of Portal Vein

The variations in the branching pattern of Portal vein within liver are mandatory factor while dealing with Subsegmental Hepatectomy. The variations in the Intra hepatic portal vein branching need to be recognized when contemplating an initial ligation of the vessels at the porta hepatis during partial hepatectomy. This study, was done in 47 adult human liver specimens and 3 fetal liver specimens. In this study different methods like manual dissection, corrosion cast and Radiological study methods used. During this study the “BIFURCATION” or “TRIFURCATION” pattern of portal vein, accessory branches from its branches and relation between, portal vein and hepatic vein were observed. The knowledge of the portal vein and its intra hepatic branching, including their variations are crucial to ensure surgical success pertaining to different and modern surgical procedures.
