Stomach arterial supply
The stomach is supplied primarily by branches of the celiac trunk. [1] The key arterial sources are the left gastric artery, the right gastric artery, the left gastroepiploic (left gastroomental) artery, the right gastroepiploic (right gastroomental) artery, and the short gastric arteries. [2]
Lesser curvature arterial supply
The left gastric artery supplies the lesser curvature of the stomach. [2] The right gastric artery supplies the lesser curvature of the stomach. [2]
Greater curvature arterial supply
The left gastroepiploic artery supplies the greater curvature of the stomach and is a branch of the splenic artery. [2] The right gastroepiploic artery supplies the greater curvature of the stomach and is a branch of the gastroduodenal artery. [2] The short gastric arteries supply the fundus and proximal greater curvature and arise from the splenic artery. [2]
Arterial anastomotic pattern
Arterial continuity along the curvatures is provided by anastomoses between the gastric arteries along the lesser curvature. [3] Anastomoses along the greater curvature are formed between the gastroepiploic arteries, with short gastric arterial branches contributing to the fundus supply. [3]
Stomach venous drainage
Venous drainage of the stomach parallels the arterial supply. [4]
Lesser curvature and greater curvature venous drainage
The left and right gastric veins drain into the portal vein. [2] The short gastric veins and the left gastroepiploic vein drain into the splenic vein. [2] The right gastroepiploic vein drains into the superior mesenteric vein. [2]
Venous destinations within the portal venous system
The venous pathway from the splenic vein and superior mesenteric vein converges via the portal vein. [5]
