Right gastric artery

The Right Gastric Artery is an artery that arises from the hepatic artery or less frequently from the common hepatic artery. It supplies blood to the lesser curvature of the stomach.

Anatomy

The right gastric artery runs from right to left along the lesser curvature of the stomach, between the layers of the lesser omentum, and anastomoses with the left gastric artery. It may arise from the hepatic artery before that vessel leaves the celiac artery. It may also arise from the common hepatic artery or from the celiac artery.

Function

The right gastric artery supplies blood to the lesser curvature of the stomach. This is the upper part of the stomach that connects to the esophagus. The right gastric artery is responsible for delivering oxygenated blood to this part of the stomach.

Clinical significance

The right gastric artery is an important structure in surgeries involving the stomach, such as gastrectomy and gastric bypass surgery. Knowledge of its anatomy is crucial for surgeons to avoid damaging it during these procedures.
