Abstract

The outcome of brain insults induced by ischemia is influenced by two major factors, recirculation disturbance and metabolic derangement. Besides the reactive hyperemia, two types of recirculation disturbance can be distinguished; the no-reflow phenomenon [1] and delayed post-ischemic hypoperfusion [2–5], those have been shown to add a secondary ischemic insult to the tissue. Excessive release of excitatory neurotransmitters (e.g., glutamate, aspartate) during ischemia has been shown to play an important role in metabolic derangement, resulting in selective hyperexcitability after ischemia which leads to postsynaptic ionic influxes (e.g., sodium, calcium), causing neuronal damage [6–8].
