Inferior pancreaticoduodenal artery

The inferior pancreaticoduodenal artery (Latin: arteria pancreaticoduodenalis inferior) is a blood vessel that branches off the superior mesenteric artery

The artery divides into anterior and posterior branches immediately after arising from the superior mesenteric artery. These two branches run between the head of the pancreas and the duodenum. The anterior branch ascends to the anterior side, while the posterior branch - to the posterior side of the head of the pancreas.

Superiorly, the anterior and posterior branches of the inferior pancreaticoduodenal artery anastomose with the anterior and posterior superior pancreaticoduodenal arteries. These anastomoses create an arterial network that supplies the head and uncinate process of the pancreas and the duodenum.
