The Pancreaticoduodenal artery refers to two arteries - the superior pancreaticoduodenal artery and the inferior pancreaticoduodenal artery - that supply blood to the pancreas and the duodenum. These arteries are branches of the gastroduodenal artery and the superior mesenteric artery, respectively.

Structure[edit | edit source]

The superior pancreaticoduodenal artery is a branch of the gastroduodenal artery, which itself is a branch of the common hepatic artery. The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery. These arteries anastomose (connect) with each other to supply blood to the head of the pancreas and the descending part of the duodenum.

Function[edit | edit source]

The pancreaticoduodenal arteries play a crucial role in supplying oxygenated blood to the pancreas and the duodenum. They ensure the normal functioning of these organs, which are vital for digestion and absorption of nutrients.

Clinical significance[edit | edit source]

Abnormalities or blockages in the pancreaticoduodenal arteries can lead to serious conditions such as pancreatitis or ischemia. Therefore, understanding the anatomy and function of these arteries is crucial in the diagnosis and treatment of such conditions.
