Anatomy of the Liver

Abstract

Thorough knowledge of anatomy and anatomical variations is a prerequisite for liver transplantation. In whole organ liver transplantation, knowledge of the anatomy of hilar structures and hepatic veins is necessary, but in split liver transplantation additional insight into intrahepatic anatomy is of paramount importance in ensuring the acquisition of two viable grafts of sufficient size and with usable vascular and biliary tributaries. Understanding of the concept of functional anatomy and segmentation of the liver forms the basis for splitting the liver for transplantation purposes. This chapter addresses both the concept of functional anatomy and the descriptive anatomy of the hepatoduodenal ligament, the intra- parenchymal branches of the portal triads and the hepatic veins. Both aspects are covered in a way that keeps in mind splitting of the liver for transplantation purposes.
