- Accessory right inferior hepatic veins
An accessory right inferior hepatic vein is the most common variation of the hepatic veins. It is present in up to 48% of the population and drains the posterior part of the right lobe (mainly segments 6 and 7) directly into the inferior vena cava (IVC).
Variations in hepatic vascular anatomy are particularly important in the setting of liver surgery, transplantation and radiological intervention.
An accessory right inferior hepatic vein can help to drain liver segments 6 that remain following bisegmentectomy 7-8 (right superior liver resection) 4.
