Superior Perspective of the Arteries of the Liver

Description

Seen from a superior perspective, the hepatic parenchyma is rendered with a semi-transparent capsule to expose the arterial arborization across the diaphragmatic surface of the liver. Proximally, the proper hepatic artery at the porta hepatis gives rise to right and left hepatic arteries that course superiorly and laterally into the right and left lobes, then divide into lobar and segmental branches that track with portal triads. Peripheral subcapsular branches spread toward the superior convexity, with the falciform ligament region marking the separation of medial and lateral territories on the left. A top-down view is useful when you need to teach or plan around the functional distribution of hepatic arterial inflow rather than the more familiar anterior porta hepatis anatomy. Segmental branching patterns matter in transarterial therapies such as chemoembolization for hepatocellular carcinoma, where catheter position and awareness of extrahepatic collaterals reduce non-target embolization to structures like the gallbladder or abdominal wall. Surgeons also lean on this spatial logic during cholecystectomy and hepatic resection, since right hepatic arterial variants and proximity to the cystic artery can change the risk profile in Calot’s triangle. Small differences matter. Use this asset in hepatobiliary anatomy lectures, interventional radiology teaching files, and surgical atlases covering hepatic lobar and segmental vascular territories in adult male anatomy. It also fits grant figures and review articles discussing hepatic arterial anatomy, variant branching, and perfusion-based treatment planning.
