Gross anatomy
Course
The hepatic artery proper runs to the right anterioranteromedial to the portal vein and medial to the left of the common bile duct to form the portal triad. These three structures maintain this position while lying in within the hepatoduodenal ligament between the duodenum and the porta hepatis, enveloped in peritoneum in the free edge of the lesser sac 1. It then terminates by bifurcating into the right and left hepatic arteries before entering the porta hepatis of the liver.
