The Applied Anatomy of Intrahepatic Ducts / 第三军医大学学报

ABSTRACT

The architectural arrangement of the intrahepatic ducts was studied on 55 specimens of normal adult liver. The right and left hepatic ducts could be categorized according to the pattern of their formation into regular and irregular types.The regular right hepatic duct formed by the union of the anterior and posterior lobar ducts was present in 27 cases (49.09%). The right anterior or right posterior lobar duct opened directly into the left hepatic duct or the common bile duct in 8 cases (14.55%). The right hepatic duct and the right anterior lobar duct were located on the anterior and sinister sides of the accompanying branches of the portal vein respectively. The right posterior lobar duct, after crossing superiorly over the root of the portal vein branch to the right anterior lobe, passed rightward.The regular left hepatic duct formed by the union of the left medial and left lateral lobar ducts was present in 18 cases (32.73%) . The main intrahepatic ducts of the left side of the liver were located on the anterior or ante-ro-medial side of the left branch of the portal vein.The problem concerning the architectural arrangement of the main intrahepatic ducts and its clinical significance was discussed.
