Left Hepatic Artery, Anterior View

Description

Arising from the proper hepatic artery at the porta hepatis, the left hepatic artery courses superiorly and to the anatomical left before arborizing within the left lobe. From an anterior perspective, its segmental branches can be followed toward Couinaud segments II and III, with a medial branch continuing toward segment IV near the falciform ligament. The vessel network sits anterior to the portal venous bifurcation in the hepatoduodenal ligament and then spreads within the hepatic parenchyma, with smaller arterioles tracking alongside portal venous and biliary radicles in the portal tracts. Depth cues are supported by the semi transparent liver, so the intrahepatic distribution remains visible. Clear visualization of the left hepatic artery matters in hepatic resection planning and transplant surgery because arterial territories do not always mirror portal territories, and accessory or replaced inflow from the left gastric artery can alter what stays perfused after ligation. In left hepatectomy and left lateral sectionectomy, preserving arterial supply to segment IV is a recurring technical point, and this view helps clarify how close the segment IV branch can run to the umbilical fissure. Small vessel details also support teaching around arterial injury and postoperative ischemic cholangiopathy, since the bile ducts rely heavily on peribiliary arterial plexus inflow. Use this illustration for hepatobiliary surgery lectures, interventional radiology teaching files on hepatic arterial mapping before chemoembolization, and anatomy or GI modules that introduce the portal triad from an anterior approach. It also suits medical publishing needs that require a clean, segment oriented depiction of left hepatic arterial branching in an adult male liver.
