Origin

The dorsal pancreatic artery arises from the proximal portion of the splenic artery, but is highly variable (Tsutsumi et al., 2014).

Course

The dorsal pancreatic artery courses posterior to splenic vein.

Branches

Gives off numerous branches, but the general pattern is that it splits into right and left branches (Tsutsumi et al., 2014). The right branch (anastomotic branch) passes to the right along the posterior surface or within the parenchyma of the pancreas. It extends to anastomose with branches of the superior and inferior posterior pancreatic arteries. The left branch, considered the terminus of the artery (terminal branch), passes along the inferior surface of the pancreas to the left into its tail anastomosing with the transverse pancreatic artery.

Supplied Structures

The dorsal pancreatic artery supplies the entire pancreas (uncinate process, head, neck, body, and tail) by contributing to arterial arcades of the pancreas.

Artery

ScienceDirect image

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
