Left Gastric Vein

Last updated: Jul 2nd, 2025

The left gastric vein (also known as the coronary vein) takes deoxygenated blood from the stomach; it runs from right to left along the stomach's lesser curvature and goes between the lesser omentum's two layers to the stomach's esophageal opening. At the opening, it receives some veins from the esophagus; after this, it turns backward and passes from left to right behind the omental bursa - or the lesser sac (this is an abdominal cavity which extends from behind the liver and stomach to below the upper part of the transverse colon) to drain directly into the hepatic portal vein. From there, the blood drains into the liver's capillary beds.
