Lateral Division of the Right Liver, Inferior View

Description

Inferior inspection of the male right liver emphasizes the lateral division of the right hepatic lobe (segment VI and, when extended posteriorly, segment VII) as it drapes over the right kidney and hepatic flexure of the colon. The visceral surface is contoured by the renal impression posteroinferiorly and the colic impression anteroinferiorly, with the gallbladder fossa lying more medial on the undersurface of the right lobe. Medially, the plane toward the porta hepatis and caudate region is implied by the fissural anatomy and the groove for the inferior vena cava posteriorly. Orientation is clear. Inferior, lateral, and posterior relationships are the point. Understanding the inferior boundary of the right lateral division matters when you are mapping Couinaud segments for surgery or interventional radiology, because the visceral impressions and the inferior margin guide you toward segmental territory even when external lobar landmarks are misleading. Segment VI is a common location for colorectal metastases and hepatocellular carcinoma, and its proximity to the right colic flexure and right kidney affects both operative exposure and the risk profile during percutaneous ablation. The groove for the inferior vena cava on the posterior aspect also frames the deep limit when mobilizing the right lobe during a right posterior sectionectomy. Use this artwork in hepatobiliary anatomy teaching for medical students and surgical trainees, in atlas plates explaining Couinaud segmentation from the visceral surface, or in operative planning documents that describe inferior approach landmarks for right-sided lesions. It also fits radiology education where inferior CT and MRI slices are correlated with surface anatomy of the right hepatic lobe. Anatomical accuracy verified by SciePro's Medical Advisory Board.
