Vein in the human body

{{{Name}}}

Latin	vena gastrica dextra

The right gastric vein (vena gastrica dextra) is a blood vessel in the human body that drains blood from the lesser curvature of the stomach and the pylorus. It is part of the venous system and plays a crucial role in the hepatic portal system.

Anatomy

The right gastric vein originates from the region of the pylorus and the lesser curvature of the stomach. It runs along the lesser curvature, parallel to the right gastric artery, and eventually drains into the hepatic portal vein. This vein is responsible for transporting deoxygenated blood from the stomach to the liver for detoxification and metabolism.

Function

The primary function of the right gastric vein is to collect blood from the stomach and transport it to the hepatic portal vein. This blood contains nutrients absorbed from the stomach, as well as metabolic waste products that need to be processed by the liver. The hepatic portal system is essential for maintaining metabolic homeostasis and detoxifying substances ingested through the digestive tract.

Clinical significance

The right gastric vein can be involved in various medical conditions, such as portal hypertension and gastric varices. In cases of portal hypertension, increased pressure in the hepatic portal vein can cause the right gastric vein to become engorged, leading to the formation of varices. These varices are prone to bleeding and can be a serious complication in patients with liver cirrhosis or other liver diseases.
