Vessel
Right gastric artery
Small artery approaching the pyloric lesser curvature
High-yield
Proper hepatic origin is the familiar pattern, but the artery can arise from other hepatic or gastroduodenal branches. Its territory is more consistent than its exact origin.
Overview
The right gastric artery reaches the pyloric region and follows the lesser curvature toward the left gastric network. Its short branches enter the gastric wall from the lesser omentum.
Reference facts
- Origin
- Commonly the proper hepatic artery, with other hepatic and gastroduodenal origins documented.
- Course
- Approaches the pylorus and travels leftward along the lesser curvature in the lesser omentum.
- Branches
- Gives small pyloric and gastric-wall branches.
- Supplies
- Supplies the pyloric region and adjacent distal lesser-curvature stomach.
- Drains to
- Associated right gastric venous blood usually enters the portal venous system.
