[Surgical importance of the topography of the vessels and bile ducts in the hepatic portal in case of their atypical branching and formation].

The portal triad was studied on 100 specimens of porta hepatis, using the methods of preparation, roentgenography and corrosion. An unusual origin of hepatic arteries was observed in 36%, atypical formation of bile ducts--in 33%, and a specific branching of the portal vein--in 15%. Different variants of vessels and bile ducts related with their specific development can be intercombined. Due to it, during surgical procedures in the region of porta hepatis it is necessary to bear in mind not only an atypical structure of each element of the Glisson system, but also the possibility of frequent combination of their different variants.
