Common hepatic artery

Dr Craig Hacking and Dr Donna D'Souza et al.

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

The CHA is a terminal branch of the celiac arter. It passes over the top of the pancreas, and downwards to the right in the lesser sac towards the first part of duodenum. It gives off the right gastric artery that runs upwards along the lesser curvature of the stomach to anastomose with the left gastric artery, which arises directly off the celiac artery. The CHA then enters the lesser omentum to pass slightly upwards where is runs posterior to the portal vein and inferior 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 (GDA) and becomes the proper hepatic artery (PHA).

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 PHA.
