The left gastric vein runs from right to left along the lesser curvature of the stomach. [2] It passes to the esophageal opening of the stomach, where it receives some esophageal veins. [2] 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. [2]
Gastric varices are dilated submucosal veins in the lining of the stomach, which can be a life-threatening cause of bleeding in the upper gastrointestinal tract.They are most commonly found in patients with portal hypertension, or elevated pressure in the portal vein system, which may be a complication of cirrhosis.
The left gastroepiploic vein (left gastro-omental vein) receives branches from the antero-superior and postero-inferior surfaces of the stomach and from the greater omentum; it runs from right to left along the greater curvature of the stomach and ends in the commencement of the splenic vein.
The greater curvature of the stomach forms the lower left or lateral border of the stomach. [3] Starting from the cardiac orifice it begins at the cardiac notch, forming an arch backward, upward, and to the left. A horizontal plane across from the cardiac notch encloses an area called the fundus of the stomach.
In terms of disease, the left gastric artery may be involved in peptic ulcer disease: if an ulcer erodes through the stomach mucosa into a branch of the artery, this can cause massive blood loss into the stomach, which may result in such symptoms as hematemesis or melaena.
Small intestine may loop through a perforation in the gastrosplenic ligament, ending lateral to the spleen and stomach. [1] This is known as gastrosplenic ligament entrapment, and is usually caused by abdominal trauma. [4] This is corrected with surgery. [1]
The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'. [1]
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 or in one of its large tributaries.
