During right hepatectomy, meticulous dissection is required to safeguard the main trunk and its larger anterior and posterior sectoral branches. Clinical Significance in Disease Pathology Pathological conditions affecting the right hepatic vein can lead to severe hepatic congestion and dysfunction.
Right Hepatic Vein Anatomy and Surgical Landmarks
While the classic description involves a single main trunk, significant anatomical variations are common. Contrast-enhanced CT angiography and magnetic resonance angiography are the primary non-invasive tools used to evaluate stenosis, thrombosis, or aneurysms.
In cases of severe stenosis causing Budd-Chiari syndrome, endovascular stenting can restore normal blood flow and alleviate portal hypertension. 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.
Right Hepatic Vein Anatomy and Surgical Landmarks
Anatomical Structure and Variations Understanding the anatomy of the right hepatic vein is paramount for surgical planning and interpreting imaging studies. 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.
