Anterior Superior Pancreaticoduodenal Artery, Anterior View

Description

Arising from the gastroduodenal artery, the anterior superior pancreaticoduodenal artery courses inferiorly along the anterior surface of the pancreatic head, running close to the concavity of the second part of the duodenum and its C shaped curve. From an anterior perspective you would expect to see it descending on the ventral aspect of the pancreas, giving small pancreatic branches medially and duodenal branches laterally toward the duodenal wall. The distal segment typically approaches an anastomosis with the anterior inferior pancreaticoduodenal artery from the superior mesenteric artery. Short branches. Tight spaces. Clear depiction of this vessel matters because it sits directly in the operative corridor of pancreaticoduodenectomy (Whipple procedure) and during mobilization of the duodenum and pancreatic head (Kocher maneuver), where arterial branches can be a source of brisk bleeding if not anticipated. The anastomotic arcade between superior (celiac trunk via common hepatic and gastroduodenal) and inferior (superior mesenteric) pancreaticoduodenal arteries also becomes clinically visible when celiac axis stenosis shifts flow demand, a setup for pancreaticoduodenal arcade enlargement and, in some patients, true aneurysm formation with risk of retroperitoneal hemorrhage. That collateral pathway is the teaching point. Use this anterior view for surgical anatomy plates, GI and hepatopancreatobiliary modules, and radiology correlation when labeling angiography or CTA of the gastroduodenal artery and pancreaticoduodenal arcades around the duodenal sweep. It also fits well in board style teaching on upper GI bleeding sources and postoperative hemorrhage after pancreatic head resection. Anatomical accuracy verified by SciePro's Medical Advisory Board.
