Clinical-anatomical features of hepatic vessels

Aim of current investigation is a study of the vascularization and angioarchitectonics of vessels of the human liver. Material for investigation was the preparations of the liver from 15 cadavers and СТ MR! and USI examinations of 35 patients without pathology of liver. СТ and MRI examinations showed that there are most frequent three major hepatic veins - right, middle and left. The left hepatic vein extends partially into the longitudinal groove and separates a quadrate lobe from the medially located II and III segments. The right hepatic vein separates the behind lying V-VIII segments from the dorsally positioned VI-VII segments. The middle hepatic vein located between the left and right hepatic lobes, which in caudal direction can be differentiated by the notional plane passing through the bed of the gallbladder. At the confluence of the inferior vena cava, the middle and left hepatic veins combine in four of six cases.
