Inferior pancreaticoduodenal artery

The inferior pancreaticoduodenal artery is given off from the superior mesenteric or from its first intestinal branch, opposite the upper border of the inferior part of the duodenum.

It courses to the right between the head of the pancreas and duodenum, and then ascends to anastomose with the superior pancreaticoduodenal artery.

It distributes branches to the head of the pancreas and to the descending and inferior parts of the duodenum.
