Abstract
The anatomical aspects of the biliary tract and its vascularization are of special surgical interest. The area of Glisson’s capsule (hilar plate) that surrounds the vasculo-biliary structures of the hepatic hilum has a great importance, as well as the crossed arterial vascularization that allows the supply flow, during the injuries of the main hepatic arteries.
Anatomical variations in the origin of the superior biliary confluent, the cystic duct, and its relationship with the cystic artery are determinants of the aspect of the triangle of Calot and keys for safe cholecystectomy and avoiding surgical injuries to the bile duct.
The length of the left hepatic duct allows a wide exposure that facilitates to make of the hepatic jejunal anastomosis, associating the Hepp-Couinaud maneuver.
The so-called hepatic pedicle is formed by the common bile duct, the portal vein, with the hepatic artery. Its structure is practically constant, but in 15% of cases the right hepatic artery is located in front of the main bile duct.
This chapter describes the anatomical structure of the biliary tract, morphological patterns, most important variations, and the relevant aspects of its vascularization.
