The position of the roots of these portal branches on the main umbilical trunk ascended in a spiraling fashion from anterior to lateral Fig. In the American model, the umbilical vein or round ligament serves as a sector boundary to subdivide the left-sided portion of the ventromedial lobe. Although segment IV is part of the left hemiliver, it is situated more to the right. Patient specific anatomy: the new area of anatomy based on computer science illustrated on liver. Germain, T. J Hepato-Biliary-Pan 5— AMIRA version 6.

  • The Couinaud classification of liver anatomy divides the liver into the left lobe into a medial- segment IV and a lateral part - segment II and III.

    In the widely used Couinaud (or "French") system of anatomy of the liver, the functional lobes Segments II and III lie medial to the falciform ligament with II superior to the portal venous supply and III inferior; Segment IV lies lateral to the. The liver is divided into three functional lobes: the right lobe, the left lobe, and the caudate lobe. The right and left lobes are further divided into 2 segments each.
    Starting at 5 weeks, the portal and umbilical veins sprouted portal-vein branches that, at 6.

    Note that there are no branches on the posterior side of the intrahepatic umbilical vein Fig. These findings show that the course of the hepatic veins is, apart from the area directly surrounding the inferior caval vein, comparable in lobated and non-lobated livers, such as the human liver.

    At CS18 6. The branching pattern of the portal and hepatic veins appears to result from the blood-distributing function of the umbilical vein and the crypto- lobar architecture of the liver, respectively.

    Couinaud classification The Couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments.

    The distribution of the hepatic veins in embryonic and adult human livers. It further demonstrates that the intrahepatic portion of the inferior caval vein derives from the most posterior hepatic vein.

    From CS14 34 days of development: Supplementary Fig. Nettelblad, S.

    It is the preferred anatomy classification system as it divides the liver into eight left lateral section: segment II above and segment III below the portal plane; left.

    The middle hepatic vein divides the liver into left and right lobes. The left hepatic vein divides the left lobe into lateral. (2, 3) and medial (4a, 4b) segments.

    3). Multiple anatomic variations, however, may also exist in the anatomy of the hepatic artery Externally, the liver is divided by the falciform ligament.
    Lobar boundaries, even in non-lobated human livers, and functional vascular requirements account for the predictable topography and branching pattern of the liver veins, respectively. Although segment IV is part of the left hemiliver, it is situated more to the right. The sinusoidal network in the developing caudate lobe formed a hepatic vein that joined the inferior caval vein on its posterior side separately from the other main hepatic veins.
