The right hepatic vein serves as a crucial landmark, generally running between the right anterior sector (segments V and VIII) and the right posterior sector (segments VI and VII). In cases of severe stenosis causing Budd-Chiari syndrome, endovascular stenting can restore normal blood flow and alleviate portal hypertension.
Surgical Preservation of the Right Hepatic Vein: Techniques and Outcomes
The right hepatic vein is a critical intrahepatic vessel responsible for draining deoxygenated blood from the right lobe of the liver. Anatomically, this vein typically originates from the posterior aspect of the liver, collecting blood from the right anterior and right posterior hepatic segments before joining the inferior vena cava just below the diaphragm.
As one of the major hepatic veins, it plays an indispensable role in maintaining hepatic hemodynamics and systemic venous return. Regular follow-up with Doppler ultrasound or MR venography helps monitor patency of stents or surgical anastomoses, ensuring optimal hepatic function and preventing complications associated with chronic venous congestion.

While the classic description involves a single main trunk, significant anatomical variations are common. Additionally, the vein serves as a critical access route for balloon-occluded retrograde transvenous obliteration (BRTO), a procedure used to control gastroesophageal variceal bleeding by isolating vascular shunts.
