anterior inferior pancreaticoduodenal artery

The anterior inferior pancreaticoduodenal artery is an artery that branches from the inferior pancreaticoduodenal artery and courses along the anterior surface of the uncinate process and head of the pancreas, supplying the uncinate process, the head of the pancreas, and the second and third parts of the duodenum.

It is found in the upper abdomen, originating from the inferior pancreaticoduodenal artery and traveling along the anterior aspect of the pancreatic head and uncinate process toward the duodenum.

Its function is to supply oxygenated blood to the anterior surface of the uncinate process and pancreatic head, as well as to the second and third parts of the duodenum, as part of the pancreaticoduodenal arterial network.

Pancreatic head tumors and pancreatitis may be associated with involvement of this artery, and its anatomical course is a key consideration during pancreaticoduodenectomy.

This artery may be evaluated using CT angiography or digital subtraction angiography, particularly in the context of pancreatic or duodenal pathology assessment.
