Intra Hepatic Pattern of Portal Vein in Dog's Liver: A Corrosion Cast Study.

ABSTRACT

Introduction: The variations in the intrahepatic pattern of portal vein within liver are mandatory factors while dealing with hepatic surgery. The variations in the intrahepatic portal vein branching need to be recognized when contemplating for ligation of the vessel at the porta hepatis during partial hepatectomy. Materials and Methods: This study was done in 50 dogs liver specimen by corrosion cast technique. Results and Discussion: In this study in the entire cases bifurcation pattern was found and in all the cases left branch of portal vein extended transversly to the left and turned in the caudolateral direction and divided into transverse portion and oblique portion and right divided into superior and inferior branch. In 88% cases caudate process received branch from the right portal trunk while the papillary process received branch from the left portal trunk. Conclusion: The knowledge of the portal vein and its intrahepatic branching is important to ensure surgical success pertaining to different surgical procedures.
