Postischemic Hyperemia

Postischemic hyperperfusion is a heterogeneous phenomenon of variable pathophysiological origin and divergent prognostic implications. Even the nomenclature is not clear, with various names and definitions for this state, i.e., hyperperfusion, hyperemia, luxury perfusion, and vasomotor paralysis. Postischemic hyperperfusion is quite a common finding in transient perfusion disturbances in animal experiments, but it can be also observed with permanent arterial occlusion and spontaneous collateral reperfusion. While postischemic hyperperfusion often develops after ischemia lasting up to 30 min and is usually followed by normal perfusion and fast recovery of function (as recorded in evoked responses), it can be observed regularly after 60-min transient ischemia but then often leads to postischemic hypoperfusion and impaired function [1].
