Origin

The inferior pancreaticoduodenal artery gives rise to anterior and posterior branches.

Course

The anterior inferior pancreaticoduodenal artery passes superior and angled slightly to the right on the anterior surface of the uncinate process of the pancreas. It travels within, or slightly to the left of the groove between the second part of the duodenum and the pancreatic head and uncinate process.

Branches

The anterior inferior pancreaticoduodenal artery terminates with small anastomotic branches that join those from the anterior superior pancreaticoduodenal artery to form an anterior pancreaticoduodenal arterial arcade.

Supplied Structures

The anterior inferior pancreaticoduodenal artery supplies the uncinate process and head of the pancreas. It also supplies the second and third parts (or descending and horizontal parts) of the duodenum.

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
