Answer

The blood supply of the stomach is rich, with overlap among the vessels. The lesser curve is supplied by the left and right gastric arteries, branches of the celiac trunk and hepatic artery, respectively. The greater curve is supplied by the right gastroepiploic artery arising from the gastroduodenal artery and the left gastroepiploic artery and the short gastric arteries originating from the splenic artery. This excellent collateral blood supply of the stomach allows the surgeon to ligate much of the arterial supply (ie, the short gastric arteries during fundoplication) without the risk of ischemia (see the image above).
