The left gastric vein (or coronary vein) is a vein that derives from tributaries draining the lesser curvature of the stomach.
Structure
The left gastric vein runs from right to left along the lesser curvature of the stomach.[1] It passes to the esophageal opening of the stomach, where it receives some esophageal veins.[1] It then turns backward and passes from left to right behind the omental bursa. It drains into the portal vein near the superior border of the pancreas.[1]
Function
The left gastric vein drains deoxygenated blood from the lesser curvature of the stomach.[1] It also acts as collaterals between the portal vein and the systemic venous system of the lower esophagus (azygous vein).[citation needed]
Clinical significance
Esophageal and paraesophageal varices are supplied primarily by the left gastric vein (due to flow reversal) and typically drain into the azygos/hemiazygos venous system.[2]
