Dorsal pancreatic artery
Review of
proximal splenic artery embolization in blunt abdominal trauma. Schematic for the dorsal pancreatic (thin white arrow) to transverse pancreatic (thick white arrow) to great pancreatic artery (curved white arrow). Short black arrows denote the direction of flow. (Black star-coils in proximal splenic artery)
Review of
proximal splenic artery embolization in blunt abdominal trauma. Transradial splenic angiogram following splenic trauma. After proximal splenic artery embolization using coils (black star), flow from the proximal splenic artery (straight white arrow) to the distal splenic artery (curved white arrow) is maintained via dorsal pancreatic (straight thin black arrow) to transverse pancreatic (straight thick black arrow) to great pancreatic artery (curved black arrow) pathway
Review of
proximal splenic artery embolization in blunt abdominal trauma. 85 year old male with pancreatic cancer status post iatrogenic trauma following drain placement for a perisplenic abscess. Splenic artery DSA after embolization shows that the AMPLATZER™ Plug (white arrow) has mistakenly been placed distal to the great pancreatic artery (curved black arrow). This excludes collateral perfusion of the spleen via the dorsal pancreatic artery (straight thin black arrow) to transverse pancreatic (thick black arrows) to great pancreatic artery pathway
The dorsal pancreatic artery is a branch of the splenic artery that supplies the pancreas. It arises from the proximal splenic artery and descends a short distance to run along the posterior margin of the pancreas where it divides in to left and right branches.
- the right branches pass either anterior or posterior to the superior mesenteric vein, suppling that part of the head and neck of the pancreas and anastomosing with branches of the pancreaticoduodenal arcade (Kirk's arcade)
- the left branch, usually singular, supplies the body and tail of the pancreas, anastomosing with branches of the transverse pancreatic artery
Variant anatomy
The dorsal pancreatic artery may arise from the superior mesenteric artery or celiac trunk .
