Collateral systems between the celiac trunk and superior mesenteric artery

There are several collateral systems between the celiac trunk and superior mesenteric artery

These include

  • gastroduodenal artery (GDA)
    • branch of the common hepatic artery and anastomoses with branches of the inferior pancreatic duodenal artery
  • dorsal pancreatic artery (DPA) 
    • usually a branch of the splenic artery, which anastomoses with the anterior and posterior pancreaticoduodenal arcades via a right transverse branch of the dorsal pancreatic artery (Kirk's arcade)
  • arc of Buhler - only present in 1-4% of individuals.
  • arc of Barkow - collateral pathway within the omentum, between the epiploic arteries of the splenic artery and superior mesenteric artery
