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.
Anatomy and Function of the Right Hepatic Vein
It drains the right lobe of the liver, which constitutes the majority of the organ’s mass. The Middle and Left Hepatic Veins The middle hepatic vein runs in the plane of the main lobar fissure, effectively separating the right and left functional lobes.
Preserving at least one hepatic vein in each functional lobe is a fundamental principle of liver surgery to maintain adequate venous drainage and prevent postoperative complications. 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.
Anatomy and Function of the Right Hepatic Vein
The left hepatic vein, often dividing into superior and inferior branches, drains the left lateral segment (segments II and III). The hepatic veins form the primary venous drainage system of the liver, responsible for transporting blood away from the organ back to the heart.
