Aberrant Confluence of Intrahepatic Biliary Ducts - A Case Report

Aim: Besides the most frequent-modal type of confluent patterns intrahepatic biliary ducts, there are cases with aberrant type of confluence. The aim of this report is to present a case with aberrant confluence of intrahepatic biliary ducts.Material and Methods: Injection-corrosive method was used to obtain acrylic cast from biliary and portal systems of one human liver. Biliary ducts were followed parallel to the adjoint portal ramification from the initial part of segmental ductules.Results: Nine portal segments of the liver were established. Segmental biliary ducts and their confluence subsequently from IV to I order, were also seen. The right hepatic duct was absent. The posterior and anterior right sectorial ducts joined consecutively the opposite left hepatic duct in front of the portal bifurcation. As to the segmental ducts 2nd segment duct inflow the left hepatic duct, then 3rd segment duct had merging pattern of double medial sector duct as well as three segmental ducts 5th, 6th and 7th had inflow pattern in posterior sector duct. This specimen with aberrant confluence of intrahepatic ducts has been selected to point out the “close” relationship of found aberrant bile ducts in the liver region.Conclusion: The knowledge of the aberrant anatomy of biliary ducts emphasizes the importance in clinical practice of basic information for portobiliary topography.
