hepatic artery proper
The hepatic artery proper, also known as the proper hepatic artery (PHA), is the continuation of the common hepatic artery after it gives off the gastroduodenal artery. Just prior to the porta hepatis it divides into the left and right hepatic arteries.
The hepatic artery proper runs anteromedial to the portal vein and medial to the common bile duct to form the portal triad within the hepatoduodenal ligament . It terminates by bifurcating into the right and left hepatic arteries before entering the porta hepatis of the liver.
There are numerous variants of the hepatic arteries. See main article: variant hepatic arterial anatomy.
