Which artery is most likely to be infected?

Dorsal pancreatic artery-the pancreas is a retroperitoneal organ, except for a small portion of its tail. the dorsal pancreatic artery would be the infected artery because it arises from the splenic artery and runs ret roperitoneally along the superior border of the pancreas behind the peritoneum. the other arteries run within layers of the peritoneum. the left gastric arteries run within the lesser omentum; the proper hepatic artery runs within the free margin of the lesser omentum; the middle colic artery runs within the transverse mesocolon; the sigmoid arteries run within the sigmoid mesocolon.
