Stomach and Duodenum GROSS ANATOMY OF THE STOMACH AND DUODENUM Arteries

The stomach has an arterial supply on both the lesser and greater curves . On the lesser curve, the left gastric artery, a branch of the coeliac axis, forms an anastomotic arcade with the right gastric artery, which arises from the common hepatic artery. The gastroduodenal artery, which is also a branch of the hepatic artery, passes behind the first part of the duodenum. Here it divides into the superior pancreaticoduodenal artery and the right gastroepiploic artery. The superior pancreaticoduodenal artery supplies the duodenum and pancreatic head, and forms an anastomosis with the inferior pancreaticoduodenal artery, a branch of the superior mesenteric artery. The right gastroepiploic artery runs along the greater curvature of the stomach, eventually forming an anastomosis with the left gastroepiploic artery, a branch of the splenic artery. The fundus of the stomach is supplied by the vasa brevia (or short gastric arteries), which arise near the termination of the splenic artery.
