The middle hepatic vein runs in the main portal fissure, dividing the liver into right and left anatomical segments, while the left hepatic vein courses along the left segmental fissure. Furthermore, the retrohepatic inferior vena cava may exhibit abnormal positioning, such as a duplicated or interrupted segment, which forces the hepatic veins to tunnel through fibrous bands.

These vessels serve as the primary drainage pathway for deoxygenated blood from the liver, emptying directly into the inferior vena cava. Understanding their precise positioning, variations, and relationships with surrounding structures is essential for interpreting imaging studies and avoiding iatrogenic injury during procedures.
Accessory hepatic veins may drain directly into the inferior vena cava, bypassing the main trunks, while absent hepatic veins can create a challenging drainage bottleneck. Precise measurement of the vein’s diameter and wall thickness provides immediate data on congestion or outflow obstruction, guiding urgent clinical decisions.

The hepatic veins are typically visualized entering the inferior vena cava at a right angle; however, in cases of thrombosis or stenosis, the flow becomes turbulent or reversed. All three veins pierce the fibrous capsule of the liver and merge into the wall of the inferior vena cava just below the diaphragm, forming a distinct intravascular sulcus.
