Anterior Gross Anatomy of the Liver

Description

Oriented in anterior anatomical position, the male liver fills the right upper quadrant with the right lobe extending farther laterally and inferiorly than the left lobe, which tapers toward the epigastrium. A falciform ligament (falciform fold) marks the anterior boundary between the lobes and tracks toward the superior surface where it meets the diaphragmatic attachment. Beneath a semi-transparent hepatic parenchyma, the hepatic venous system branches centripetally toward the superior posterior aspect of the organ, converging into the right, middle, and left hepatic veins as they approach the inferior vena cava. Portal triads are not the emphasis here. Emphasis on hepatic veins makes this view practical for teaching venous outflow and segmental anatomy: the right hepatic vein typically runs in the intersegmental plane between the anterior and posterior sectors, while the middle hepatic vein often aligns with Cantlie’s line between right and left functional hemilivers, a relationship surgeons exploit in right hepatectomy and living-donor graft planning. Venous congestion patterns also map onto this architecture, including Budd-Chiari syndrome (hepatic venous outflow obstruction) and the outflow considerations that drive the placement and follow-up of a TIPS in portal hypertension. Clamping and bleeding control start here. Use this artwork in gross anatomy and hepatobiliary surgery teaching to connect surface landmarks (falciform ligament, lobar contours) with the internal drainage toward the inferior vena cava, and in radiology or pathology content to mirror the logic used when reading contrast-enhanced CT or MR venography of hepatic veins. It also suits journal figures discussing hepatic resection planes, venous variants, and transplant outflow reconstruction. Anatomical accuracy verified by SciePro's Medical Advisory Board.
