The common hepatic artery (CHA) is one of the 3 branches of the celiac artery.

Gross anatomy

Origin

The common hepatic artery is normally a terminal branch of the celiac arter y, the largest branch coursing to the right.

Course

It passes anterior to the pancreas, and then inferiorly to the right in the lesser sac towards the first part of duodenum. It gives off the right gastric artery, which runs superiorly along the right half of the lesser curvature of the stomach to anastomose with the left gastric artery. The common hepatic artery then passes slightly upwards where it runs anterior to the portal vein and medial to the common bile duct in the free edge of the lesser omentum. As it courses towards the porta hepatis it gives off the gastroduodenal artery inferiorly, after which it becomes the proper hepatic artery.

Branches

- proper hepatic artery
- gastroduodenal artery

Variant anatomy

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

A single or double cystic artery may arise off the proper hepatic artery.
