The pancreas is a high vascular structure and supplied by the
following arteries:
1. Splenic artery, a branch of coeliac trunk: The splenic
artery is the branch of coeliac trunk and it is the main
source of blood supply to the pancreas. Its branches
supply the body and tail of pancreas. Two branches are
named. One large branch which arises near the tail and
runs toward the neck is called arteria pancreatica magna.
Another relatively small branch, which runs toward the
tip of the tail, is termed arteria caudae pancreatica.
2. Superior pancreaticoduodenal artery: The superior
pancreaticoduodenal artery is a branch of gastroduodenal
artery.
3. Inferior pancreaticoduodenal artery: The inferior
pancreaticoduodenal artery is a branch of superior
mesenteric artery.
Both the superior and inferior pancreaticoduodenal
arteries divide into anterior and posterior branches, which
run between the concavity of the duodenum and the head of
pancreas. The anastomoses between anterior and posterior
branches form anterior and posterior pancreaticoduodenal
arterial arcades.
