    Author: Rusanov VP, Tsvetov EP.
    Journal: Arkh Anat Gistol Embriol; 1978 Nov; 75(11):80-6. PubMed ID: 736805.
    Abstract:
    Anatomical structure of the dog liver has been studied in 82 isolated preparations. Besides the external surface of the organ, the study has been carried on in preparations of intraorganic branches of the portal vein, hepatic veins. Roentgenography of the portal vein and the hepatic artery has been performed. According to the external composition and intraorganic branching of the portal vein and the hepatic artery, two separate lobes--right and left--can be determined in the dog liver. The right lobe consists of two segments, the left one has five segments. Their classification is presented. From the left hepatic lobe, blood outflows along the hepatic veins which open into the posterior vena cava by their common orifice. The right portions of the fifth segment, segments 6, 7 are drained by veins having their own orifices. The hepatic artery has 3--4 branches: the left carrying blood to 1, 2, 3 segments, middle supplying with blood 4, 5 segments and gall bladder, one--two right branches going to 6, 7 segments.
