Definition
The right gastric vein is a venous vessel that runs along the lesser curvature of the stomach within the lesser omentum.
Anatomy
The right gastric vein parallels the right gastric artery and drains blood from the distal portion of the lesser curvature, including the distal stomach body and the pyloric part of the stomach. It empties directly into the portal vein. The right gastric vein forms an anastomotic arch with the left gastric vein, which ascends from the body of the stomach to the fundus, creating a venous loop around the lesser curvature.
Branches
- Prepyloric vein: A tributary draining the area near the pylorus.
