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 gastroepiploic artery, superior pancreaticoduodenal artery

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

It supplies blood to the pylorus (distal part of the stomach) and the proximal part of the duodenum.

It arises from the common hepatic artery and terminates in a bifurcation, when it splits into the right gastroepiploic artery and the anterior superior pancreaticoduodenal artery.

Pathology

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