These veins originate within the liver parenchyma, collect blood from the hepatic sinusoids, and converge as they exit the liver capsule near the porta hepatis. The hepatic veins form the primary venous drainage system of the liver, responsible for transporting blood away from the organ back to the heart.
Three Main Hepatic Veins Overview: Anatomy and Drainage Pathway
Budd-Chiari syndrome, a rare but serious condition, involves the obstruction of the hepatic veins, typically by thrombosis. Together, these veins ensure that blood from the left lobe is efficiently collected and routed to the systemic circulation.
It drains the right lobe of the liver, which constitutes the majority of the organ’s mass. The portal vein delivers nutrient-rich, deoxygenated blood from the gastrointestinal tract and spleen to the liver for processing.

Understanding this pathway is fundamental to comprehending liver physiology and the systemic circulation. Surgical and Anatomical Considerations For surgeons performing major liver resections, a detailed understanding of the hepatic venous anatomy is paramount.
