Table 1 Classification of three types of hypermia described by Graf R, et al.
From: Microvessel changes after post-ischemic benign and malignant hyperemia: experimental study in rats
Classification | Manifestation | Quality |
|---|---|---|
Type 1 | showed immediate hyperperfusion lasting for the whole observation period and covering a large part of the ischemic territory | malignant hyperemia |
Type 2 | hyperperfusion was transient, and was often followed by hypoperfusion in some parts of the previously hyperperfused regions | benign hyperemia |
Type 3 | hyperperfused regions grew progressively | benign hyperemia |
