The superior pancreaticoduodenal artery is a blood vessel that supplies oxygenated blood to the head of the pancreas and the duodenum, which is the first part of the small intestine. It branches off from the gastroduodenal artery, itself a branch of the common hepatic artery. This artery plays a crucial role in the vascularization of these digestive organs. This artery typically divides into anterior and posterior branches, which further supply the pancreatic tissue and the duodenum. Understanding the anatomy and function of the superior pancreaticoduodenal artery is important in surgical procedures involving the pancreas and surrounding structures, as well as in diagnosing related medical conditions.
