gastric vein

In the abdomen, some drain to the left gastric vein.

Other tributaries of the hepatic portal vein include the cystic and gastric veins.

Gastric vein can refer to:

Most commonly, extrahepatic shunts are found connecting the portal vein or left gastric vein to the caudal vena cava.

The right gastric vein (pyloric vein) drains blood from the lesser curvature of the stomach into the hepatic portal vein.

Between the layers of the lesser omentum, where they are attached to the stomach, run the right and left gastric arteries, as well as the gastric veins.

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.

Barsoum et al reported a post mortem finding after sclerotherapy of portal veing thrombus extending into the left gastric vein and the submucosal plexus of the oesophagus.

Gastric varices may also be found in patients with thrombosis of the splenic vein, into which the short gastric veins which drain the fundus of the stomach flow.

The remaining blood from the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein (coronary vein), which in turn drains directly into the portal vein.

As the short gastric veins of the fundus of the stomach drain into the splenic vein, thrombosis of the splenic vein will result in increased pressure and engorgement of the short veins, leading to varices in the fundus of the stomach.

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 lienal vein or in one of its large tributaries.

DSRS is typically done with splenopancreatic and gastric disconnection (ligation of the gastric veins and pancreatic veins (that drain into the portal vein) and complete detachment of the splenic vein from the portal venous system), as it improves the outcome.

To determine the tissue type plasminogen activator activity in the regional blood of rat stomach, a 200 l blood sample was collected from the gastric vein before and after the injection of endothelin-1 which was then transferred to a glass container containing 10 l disodium citrate dihydrate (0.13 M).
