The most common pathway for the development of collateral circulations was the peripancreatic network (16/22, 72.7%) including pancreaticoduodenal arcades (14/22, 63.6%) and dorsal pancreatic artery (2/22, 9.1%).
Dorsal pancreatic artery (1/16, 6.3%), jejunal artery (1/16, 6.3%), and left gastric artery (1/16, 6.3%) were found to have one aneurysm each (Figs.
Forceps separating the portal vein (PV) and body of pancreas (P) for demonstration of the superior mesenteric artery (4), dorsal pancreatic artery
(6), left renal vein (7), and left suprarenal vein (8).
When pancreatic division must be deviated towards the body, the dorsal pancreatic artery
and collaterals of both the SMA and the SMV (from the lower edge of the pancreas) are divided.
The body and tail of the pancreas are supplied by branches of the splenic artery, including the dorsal pancreatic artery
The dorsal pancreatic artery arose from the coeliac trunk just anterior to the origin of common hepatic artery.
The coeliac trunk typically gives rise to three major branches, the left gastric artery, the hepatic and the splenic arteries; it may likewise give rise to one or both the inferior phrenic arteries or to a branch, the dorsal pancreatic artery to the pancreas (2).
Studies indicated that the collateral routes were immediately evident during HAO and that most collateral arteries originated from the inferior phrenic artery (IPA), the SMA, celiac axis, LGA, or the dorsal pancreatic artery
We may emphasize that authors like Michels (1951; 1953a,b) and Rio Branco found one dorsal pancreatic artery
and one middle colic artery originating in the celiac trunk, this fact not found by us.
