Detailed Inferior Access Point to the Anterior Medial Segment of the Male Liver

Description

Oriented from an inferior aspect, the adult male liver is presented with attention on the anterior medial segment (Couinaud segment V) within the right hepatic lobe. Segment V lies anterior and inferior to the main portal fissure and sits lateral to the gallbladder fossa, with its inferior surface approaching the visceral impressions that contact the transverse colon and duodenum. The quadrate lobe region (segment IV) occupies a more medial position, while the porta hepatis and hilar plate are situated posterior and superior relative to the inferior margin in this viewpoint. Access to segment V matters because it is a frequent target in hepatobiliary surgery and interventional radiology, where segmental anatomy determines safe planes for resection and ablation. An inferior perspective aligns with operative exposure during cholecystectomy and right hepatectomy, when the surgeon must respect the proximity of segment V parenchyma to the cystic plate, gallbladder bed, and the right anterior sectoral inflow. Bleeding and bile leak risks concentrate here. Clear segmental orientation also supports interpretation of lesion location described as “segment V” on CT or MRI reports, which directly guides approach selection and margin planning. Educators can integrate this artwork into gross anatomy labs on liver surface anatomy, surgical anatomy modules covering Couinaud segmentation, or radiology teaching files that correlate visceral surface landmarks with segmental localization. Publishers will find it fits hepatobiliary procedure atlases, patient-facing surgical consent materials, and journal figures describing right-lobe tumors, abscess drainage, or post-cholecystectomy complications near the gallbladder fossa.
