Common hepatic artery

The common hepatic artery (CHA) is a terminal branch of the coeliac artery.

Origin and course

The CHA is a terminal branch of the coeliac artery, it passes to the right in the lesser sac, and enters the lesser omentum to pass slightly upwards towards the porta hepatis. It gives off the right gastric artery that runs along the lesser curvature of the stomach to anastomose with the left gastric artery.  The common hepatic artery then bifurcates into the gastroduodenal artery and proper hepatic artery.

Branches

Variation in hepatic arterial anatomy is seen in 40-45% of people.  Classic branching of the common hepatic artery from the coeliac artery, and the proper hepatic artery into right and left hepatic arteries to supply the entire liver, is seen in only 55-60%.
