The anterior branch (ABr) concerning the system of intrahepatical biliary ducts joins with the posterior branch resulting the right hepatical duct. On a studied material represented by 120 hepatic corrosion casts, we analyzed the major anatomical variations concerning the formation and drainage of the ABr. The corrosion casts were made by injecting the hepatic vasculoductal systems with plastic, followed by corrosion of the hepatic parenchyma with hydrochloric acid. The study revealed four distinctive morphological types: TI (modal – 80.82%), when the ABr joins with the posterior one in order to result the right hepatical duct; TII (2.50%) when the ABr is absent as a morphological entity, and the segmental ducts V and VIII drain in the superior biliary confluent together with the posterior branch. TIII (15.84%), when the ABr formes the superior biliary confluent together with the left hepatic duct; TIV (0.83%), when the ABr drains into the last portion of the left hepatic duct. Knowing these major anatomical variations facilitate the surgeon to perform interventions of reglate hepatical resection.
