Left Gastric Vein
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. It passes to the esophageal opening of the stomach, where it receives some esophageal veins. 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. Function The left gastric vein drains deoxygenated blood from the lesser curvature of the stomach. It also acts as collaterals between the portal vein and the systemic venous system of the lower esophagus (azygous vein). 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.Siegelman, E.: "Body MRI", page 47.

Right Gastric Vein
The right gastric vein (pyloric vein) drains blood from the lesser curvature of the stomach into the hepatic portal vein. It is part of the portal circulation. Structure The right gastric vein passes right along the lesser curvature of the stomach to the pylorus. Once there, it joins onto the portal vein before the duodenum The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine .... The prepyloric vein is the last connecting branch onto the right gastric vein, marking the end of the stomach, and draining the proximal part of the duodenum. Function The right gastric vein drains deoxygenated blood from the lesser curvature of the stomach.

Short Gastric Veins
The short gastric veins, four or five in number, drain the fundus and left part of the greater curvature of the stomach, and pass between the two layers of the gastrolienal ligament to end in the splenic vein The spleen is an organ found in almost all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The word spleen comes .
