Indications for Extra-Intracranial Bypass Procedure: Clinical Aspects

  • Gerhard Kletter


A transient ischemic attack (TIA) is a focal disturbance of the cerebral circulation, often recurrent, that causes impaired function lasting a short period of time which then recovers without residual disability. The shortest attack is only a few seconds long, most attacks last an average of 10 to 20 minutes, and others last for several hours. The duration of the attack, within the definition, is arbitrary; most authors, however, accept a maximum period of 24 hours.
