Pancreatic microcirculatory changes in experimental pancreatitis of graded severity in the rat.

Abstract

We conclude that (1) IVM and DRS provide both unique and complementary data on tissue perfusion of the pancreas, (2) that moderate and severe experimental pancreatitis are accompanied by progressive tissue ischemia, and (3) that significant stasis (decreased perfusion) and decreased oxygen saturation occur whereas generalized vasoconstriction (decreased hemoglobin levels) was not found. In contrast, mild experimental pancreatitis was accompanied by initial hyperperfusion and normal oxygen delivery was maintained.
