Duodenal branches of anterior superior pancreaticoduodenal artery

The duodenal branches of the anterior superior pancreaticoduodenal artery are small arterial branches that arise from the anterior superior pancreaticoduodenal artery (a terminal branch of the gastroduodenal artery, itself originating from the common hepatic artery of the celiac trunk). These branches supply the duodenal wall, specifically the first and second portions of the duodenum.

Anatomical Overview

The anterior superior pancreaticoduodenal artery courses along the anterior surface of the head of the pancreas within the concavity of the duodenal C-loop. As it descends, it gives off small duodenal branches that penetrate the medial wall of the duodenum to supply its mucosa, submucosa, and muscular layers. These duodenal branches form an important part of the dual blood supply to the duodenum, complementing the posterior superior pancreaticoduodenal artery and the inferior pancreaticoduodenal arteries (branches of the superior mesenteric artery).
