Anterior Perspective of the Dorsal Pancreatic Artery

Description

Arising from the proximal splenic artery, the dorsal pancreatic artery courses inferiorly and medially behind the posterior wall of the stomach to reach the superior border of the pancreatic neck, then runs along the posterior surface of the gland toward the body. From this anterior perspective, the vessel is seen branching into transverse pancreatic branches that spread laterally across the body of the pancreas, with smaller descending rami toward the uncinate process and adjacent duodenal loop. The celiac trunk and abdominal aorta sit posterior and slightly medial to the pancreatic head and neck, while the inferior vena cava lies posterior and to the right; the spleen remains left lateral, with the liver superior right under the costal margin. Nearby hollow viscera, including the stomach and proximal small intestine, provide anterior soft tissue context. Recognizing the dorsal pancreatic artery matters when you are planning pancreatic surgery or interpreting angiography, because it often forms key anastomoses with the greater pancreatic artery and the pancreaticoduodenal arcades, buffering perfusion when one inflow is compromised. Injury during pancreaticoduodenectomy, distal pancreatectomy, or splenectomy can contribute to ischemia of the pancreatic neck and body and can complicate bleeding control in the lesser sac. Variants are common. A dorsal pancreatic artery may arise directly from the celiac trunk, common hepatic artery, or superior mesenteric artery, changing the expected pattern of collateral circulation. Surgical anatomy courses, interventional radiology teaching files, and textbook chapters on pancreatic blood supply will all benefit from this clear anterior mapping of the dorsal pancreatic artery in relation to the aorta, inferior vena cava, and neighboring upper abdominal organs. It also fits well in patient education materials explaining hemorrhage risk and arterial preservation during pancreatic and splenic procedures.
