It runs from right to left along the greater curvature of the stomach, between the layers of the greater omentum, anastomosing with the left gastroepiploic artery, a branch of the splenic artery.

Except at the pylorus where it is in contact with the stomach, it lies about a finger's breadth from the greater curvature.

This vessel gives off numerous branches: The right gastroepiploic artery was first used as a coronary artery bypass graft (CABG) in 1984 by John Pym and colleagues at Queen's University.

It has become an accepted alternative conduit, and is particularly useful in patients who do not have suitable saphenous veins to harvest for grafts.
