The common hepatic artery is one of the 3 primary branches of the celiac trunk, the other two being the splenic artery and the left gastric artery. Typically the common hepatic artery has 3 branches. The hepatic artery proper, which gives off a cystic artery to the gallbladder, and a left and right hepatic artery to the liver. The right gastric artery, which supplies the right half of the lesser curvature of the stomach. And the gastroduodenal artery, which splits to form the right gastro-omental artery (supplies right half of the greater curvature of the stomach) and the superior pancreaticoduodenal artery, which supplies part of the pancreas and duodenum.
