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]
These veins have no part in the development of esophageal varices. The lower one third of the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein, which in turn drains directly into the portal vein. These superficial veins (normally only approximately 1 mm in diameter) become ...
The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein, posterior intercostal vein and bronchial veins. [citation needed] In the abdomen, some drain to the left gastric vein which drains into the ...
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.
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 .
Venography (also called phlebography or ascending phlebography) is a procedure in which an X-ray of the veins, a venogram, is taken after a special dye is injected into the bone marrow or veins. The dye has to be injected constantly via a catheter, making it an invasive procedure.
The greater curvature, which begins at the cardiac notch, and arches backwards, passing inferiorly to the left, [1] is four or five times longer than the lesser curvature, [2] which attaches to the hepatogastric ligament and is supplied by the left gastric artery and right gastric branch of the hepatic artery. [1]
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.
