Gastric branches of left gastroomental artery

The Gastric branches of the left gastroomental (left gastroepiploic) artery are small arterial branches that arise from the left gastroomental artery and ascend to supply the greater curvature of the stomach.

Origin: The left gastroomental artery is a branch of the splenic artery, one of the major branches of the celiac trunk. As it courses along the greater curvature of the stomach within the greater omentum, it gives off multiple short gastric branches.

Course: These gastric branches ascend from the left gastroomental artery through the gastrosplenic and gastrocolic ligaments to reach the gastric wall. They penetrate the muscular layers of the stomach to supply the body and fundus along the greater curvature.

Distribution: The branches supply the anteroinferior and posteroinferior walls of the stomach, primarily along the left portion of the greater curvature. They anastomose with:

• The short gastric arteries (superiorly)

• The gastric branches of the right gastroomental artery (inferiorly and to the right), forming an arterial arcade along the greater curvature
