Gastroduodenal artery

Artery: Gastroduodenal artery
The celiac artery and its branches.
Branches of the celiac artery. The gastroduodenal artery appears on the left part of the figure and overlays/is anterior to the portal vein. The stomach is raised and inverted - compare with celiac artery branches - stomach in situ.
Latin arteria gastroduodenalis
Gray's subject #154 604
Supplies pylorus, proximal duodenum
Source common hepatic artery   
Branches Right gastroepiploic artery, superior pancreaticoduodenal artery

In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen.

It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum, and indirectly to the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries).

It most commonly arises from the common hepatic artery of the celiac trunk, but there are numerous variations of the origin [1]. It terminates in a bifurcation when it splits into the right gastroepiploic artery and the superior pancreaticoduodenal artery, which in turn has anterior and posterior branches. These branches form functional anastomoses with the anterior and posterior inferior pancreaticoduodenal arteries from the superior mesenteric artery.

Pathology

The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.
