Quick Facts
Origin: Splenic artery.
Course: Passes inferiorly and to the right along the greater curvature of the stomach.
Branches: Numerous gastric arteries and omental arteries.
Supplied Structures: Stomach, greater omentum.
Origin
The left gastroomental artery arises from the distal end of the splenic artery close to the hilum of the spleen.
Course
The left gastroomental artery passes inferiorly and to the right between the layers of the mesentery arising from the greater curvature of the stomach and contributing to the greater omentum. The artery extends along the greater curvature of the stomach usually terminating by anastomoses with the right gastroomental artery.
Branches
The left gastroomental artery gives rise to numerous small gastric arteries that pass anterior and posterior to the stomach forming a dense arterial arcade with branches from other arteries. Omental (epiploic) branches pass inferiorly between layers of mesentery.
Supplied Structures
The left gastroomental artery supplies the stomach (primarily fundus and body) and the greater omentum.
