Abstract

While intracranial ischemic insults often result in neuronal death and permanent neurological deficits, some patients may develop potentially reversible neurological dysfunction from persistent hypoperfusion, as surviving neurons remain in an “idling” state. We report a unique series of three patients with long-standing neurological deficits who underwent EC-IC bypass for repeated TIAs and demonstrated unexpected, rapid resolution of long-standing pre-existing neurological deficits. We suggest that these individuals harbored regions of underperfused, idling neurons that responded rapidly to restored cerebral reperfusion.
