Inferior pancreaticoduodenal artery

Dr Mohamed Saber and Dr Henry Knipe et al.

The inferior pancreaticoduodenal artery is the first branch of the superior mesenteric artery (SMA).

It usually arises at the inferior border of the pancreas or with the first jejunal artery as part of the pancreaticoduodenojejunal trunk. 

It anastomoses with branches of the superior pancreaticoduodenal artery (from the gastroduodenal artery) and it supplies the head of the pancreas and the duodenum distal to the ampulla of Vater.
