Right gastric artery
The right gastric artery arises, in most cases, from the proper hepatic artery, descends to the pyloric end of the stomach, and passes from right to left along its lesser curvature, supplying it with branches, and anastomosing with the left gastric artery. It can also arise from the region of division of the common hepatic artery, the left branch of the hepatic artery, the gastroduodenal artery, and most rarely, the common hepatic artery itself.
