Anatomical Course and Termination Typically, the hepatic veins are categorized into right, middle, and left divisions based on their drainage territory. Pathology and Clinical Consequences Disease processes frequently alter the hepatic vein location or obscure them entirely.
Identifying Hepatic Vein Location Variants in Imaging and Anatomy
Invasive malignancies, such as hepatocellular carcinoma or metastatic deposits, can encase the veins, turning a potentially curative resection into a palliative procedure. Understanding their precise positioning, variations, and relationships with surrounding structures is essential for interpreting imaging studies and avoiding iatrogenic injury during procedures.
The right hepatic vein is the largest and most consistent, traveling in the right hepatic fissure to enter the inferior vena cava at the level of the 5th to 6th thoracic vertebra. 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.

The portal vein branches run posteriorly to the hepatic arteries and bile ducts, meaning that dissection deep to the portal triads inevitably leads to the hepatic veins. 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.
