Right gastroepiploic artery

Last revised by Travis Fahrenhorst-Jones on 13 Aug 2022

The right gastroepiploic artery (RGA) arises from the gastroduodenal artery as it divides into its two terminal branches; the right gastroepiploic artery and the superior pancreaticoduodenal artery.

Gross Anatomy


The RGA passes between the first part of the duodenum and the pancreas, then turns left to enter between the two layers of the greater omentum along the greater curvature of the stomach. This anastomoses with the left gastroepiploic artery, which arises from the splenic artery.


The RGA has branches that supply both the anterior and posterior surfaces of the stomach.

Both left and right gastroepiploic arteries give off branches known as the epiploic branches that pass inferiorly between the two layers of the greater omentum. These branches pass over the transverse colon, but do not supply it.
