title: Termination of the ligamentum venosum and the topographic relationship between the left portal vein, left hepatic artery, and ligamentum venosum in the fissures for the ligamentum teres and ligamentum venosum.
abstract: OBJECTIVE
  The aim of this study was to clarify the location of termination of the ligamentum venosum (LV) and topographic relationships between the left portal vein (LPV), left hepatic artery (LHA), and LV in the fissures for ligamentum teres and LV.
  
  
  METHODS
  Anatomical examination was performed on 50 livers from embalmed Korean adult cadavers.
  
  
  RESULTS
  The LV originated from a point between the transverse and umbilical portions of LPV (Tr-Um point) in all specimens, and terminated in the common trunk of the middle hepatic vein and left hepatic vein (LHV) (61%) or in the LHV (39%). In the fissures for ligamentum teres and LV, the courses of the LHA relative to the LV and the LPV varied, such that four main patterns could be discerned. In type I (48%), the LHA crossed the inferior surface of Tr-Um point and passed just left of the origin of LV. In type II (20%), the LHA crossed the inferior surface of umbilical portion of LPV. In type III (10%), the LHA crossed the inferior surface of Tr-Um point to pass just left of origin of LV, with one branch of the right hepatic artery crossing the inferior surface of umbilical portion of LPV. In type IV (12%), no arterial branches ran on the inferior surfaces of transverse and umbilical portions of LPV.
  
  
  CONCLUSIONS
  These details may play a role as external landmarks for facilitating preestimation of intrahepatic structures during various surgical procedures involving the liver.
