Arteria gastrica sinistra

Arteria Gastrica Sinistra or the Left Gastric Artery is one of the three branches of the Celiac Trunk, a major branch of the Abdominal Aorta. It is a significant artery in the Human Anatomy that supplies blood to the lesser curvature of the Stomach and part of the Esophagus.

Anatomy

The Left Gastric Artery arises from the celiac trunk and runs along the lesser curvature of the stomach. It often gives off esophageal branches which ascend to supply the esophagus. The artery may also give off a hepatic branch that can replace or supplement the Hepatic Artery.

Clinical Significance

The Left Gastric Artery is of particular importance in Gastroenterology and Surgery. It is often ligated in surgical procedures involving the stomach, such as a Gastrectomy. In addition, it can be a source of significant bleeding in conditions such as Peptic Ulcer Disease or Gastric Cancer.
