Vascular supply of the stomach

General

The stomach serves as a temporary reservoir for the food ingested. This is where the digestive process begins.

Arterial supply

The arterial supply of the stomach (Gastric vascular supply) is comparatively complex. From an anatomical point of view, one differentiates in the stomach the lesser curvature (Curvatura minor) and the great curvature (Curvatura major), which are supplied differently. The lesser curvature is formed by the right and left gastric arteries (Arteriae gastricae dextrae et sinistrae). The right hepatic artery arises from the hepatic artery (Common hepatic artery), while the left hepatic artery from the Celiac trunk arises. The great curvature is supplied by the right and left gastric mesh arteries (Arteriae gastroomentales dextra et sinistra). The left gastric mesh artery arises from the splenic artery (Splenic artery), while the right gastric mesh artery emerges from the gastric and small intestinal artery (Gastroduodenal artery) arises. But they all come from different branches Arteriesthat supply the stomach from the celiac trunk, which has its exit from the main artery (aorta).

Venous drainage

Of the venous outflow of the lesser curvature (Gastric vascular supply) runs through the right and left gastric veins (Venae gastricae dextra et sinistra), that of the great curvature via the right and left gastric network vein (Venae gastroomentales dextra et sinistra). All venous vessels of the stomach finally flow into the Portal vein (Vena Portae) the liver.
