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 pancreas via branches.

It arises from the common hepatic artery and 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 a functional anastomosis with the inferior anterior and inferior posterior 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.
