Anterior Perspective of the Arteries of the Liver

Description

Presented from an anterior perspective, the male liver is rendered semi-transparently to relate capsular landmarks to the intrahepatic arterial tree. The hepatic artery proper ascends in the hepatoduodenal ligament and enters the porta hepatis, then divides into right and left hepatic arteries that course superiorly and laterally into lobar and segmental branches within the parenchyma. Along the inferior margin of the organ, the porta region sits medial to the right lobe and lateral to the left lobe, establishing the typical orientation for tracing arterial inflow. A vertical esophageal silhouette is included superiorly and slightly posterior, giving a useful relationship to the left lobe and gastroesophageal junction. Arterial anatomy at the porta hepatis matters because it defines safe planes for hepatobiliary surgery and explains patterns of ischemic complication. During cholecystectomy and hilar dissection, confusion between the right hepatic artery, cystic artery, and adjacent biliary structures drives bleeding risk and bile duct injury, so a clean anterior read of the hepatic artery proper and its early bifurcation is a practical teaching target. Segmental branching also underpins Couinaud-based liver resections and helps correlate why selective hepatic arterial embolization can spare uninvolved segments while treating hepatocellular carcinoma. Small variations change everything. Use this plate in gross anatomy and surgical anatomy courses to teach the porta hepatis as a landmark and to reinforce lobar and segmental arterial territories, or in hepatobiliary texts and interventional radiology materials discussing hepatic arterial catheterization and embolotherapy. It also fits clinical slide decks for transplant, where recipient hepatectomy and arterial anastomosis depend on rapid recognition of the hepatic artery proper and its branches.
