Left gastric artery

Left Gastric Artery

The Left Gastric Artery is an artery that arises from the Celiac Trunk and runs along the lesser curvature of the Stomach. It is one of the three branches of the celiac trunk, the other two being the Common Hepatic Artery and the Splenic Artery.

Anatomy

The left gastric artery is the smallest among the three branches of the celiac trunk. It arises from the front of the aorta, just below the diaphragm, and runs forward to the lesser curvature of the stomach. It may give off esophageal branches.

Branches

The left gastric artery typically gives off esophageal branches. These branches may arise from the aorta, and not directly from the left gastric artery. They ascend to the Esophagus, and anastomose with branches of the Inferior Thyroid Artery.

Clinical Significance

The left gastric artery is of clinical significance as it supplies blood to the lesser curvature of the stomach. It is often ligated in surgical procedures involving the stomach, such as a Gastrectomy.
