Abstract

Hyperemia after focal cerebral ischemia generally develops in two situations. Hyperemia in the surrounding area of infarction is sometimes observed in clinical cases accompanied by local hypometabolism. Hyperemia in the ischemic focus, on the other hand, usually results from recanalization to an area damaged by ischemia and may cause hemorrhagic infarction.
