Abstract
156 abdominal preparations were explored by arteriography, corrosion and dissection. The stomach is vascularized by four well-anastomosed main arteries: the arteria gastrica dextra and sinistra and the arteria gastroepiploica dextra and sinistra. Other important vessels include: the arteria gastroduodenalis, the arteriae gastricae breves for the upper half of the greater curvature, a posterior gastric artery (36%), an accessory left gastric artery (12%) and an arteria supraduodenalis. The main vessels give rise to some very specific collaterals, e.g. the omental arteries that may form an omental arcade (44%), supra- and infra-pyloric branches, retroduodenal branches, rami cardiaci, esophagei and tuberales and an accessory left hepatic artery. The gastroduodenal artery always arises at a fixed point.
