It contributes to the blood supply of the stomach and greater omentum.

Course
The left gastroepiploic artery arises as a terminal branch of the splenic artery, just proximal to the hilum of the spleen.
It first travels within the gastrosplenic ligament and then between the anterior and posterior layers of the greater omentum.
Remaining within the greater omentum, the left gastroepiploic artery traverses along the greater curvature of the stomach. It terminates by anastomosing with the right gastroepiploic artery.

Supply
The left gastroepiploic artery gives rise to both gastric and omental branches:
- Gastric branches – supply the fundus and body of the stomach.
- Omental branches – supply the greater omentum.
