Abstract:
The relationship between the hepatic vein and the Glisson's system was studied on 59 cast specimens of normal adult liver. There are 3 large branches of the hepatic vein, that is, the sinister, medial and dexter hepatic veins. The trunk formed by the union of the sinister and medial hepatic veins is present in 79.66% of the cases.The sinister vein with its middle branch crosses in front of the superior segmental portal vein and behind the inferior segmental portal vein of the left lateral lobe of the liver. At the crossing point, the two veins are close to each other.The medial hepatic vein is situated in the medial fissure of the liver. In 62.50% of cases, the medial hepatic vein crosses over the transverse portion of the left branch of the portal vein, while in 31.25% of cases, it crosses over the bifurcation of the portal vein. At the crossing point, the distance between the two veins is about 1 cm.The infero-posterior branch of the dexter hepatic vein crosses over the right posterior branch of the portal vein, At the crossing point, the distance between the two veins is about 0.5 cm.The crossing points mentioned above are useful to perform an intrahepatic cholangiography or establish a porto-systemic shunt by way of trans-jugulo-hepatic vein catheterization.
