Unusual blood supply to the pancreas by a dorsal pancreatic artery.
A variation of the blood supply to the pancreas was observed in an 89-year-old female, in which the celiac trunk gave off four arteries: the hepatic, splenic, left gastric arteries and an additional dorsal pancreatic artery. One of the branches the dorsal pancreatic artery joined with the superior mesenteric artery to form a longitudinal anastomosis. The anterior and posterior pancreaticoduodenal arcades arose from branches of the superior pancreaticoduodenal and the dorsal pancreatic arteries. The inferior pancreaticoduodenal artery, a branch of the superior mesenteric artery, was missing. The majority of the pancreas was, therefore supplied by the dorsal pancreatic artery. The clinical implications of this finding are that the size, location and course of a dorsal pancreatic artery should be established given its central role in the blood supply to the pancreas observed in the present study.
