Low clinical ischemic threshold for cerebral blood flow in severe acute brain trauma

Abstract

✓ A case of severe acute brain trauma is presented in which the patient made a satisfactory recovery after suffering a marked reduction in cerebral blood flow, to a level previously reported in association with impending brain death (10 ml/100 gm/min). This is believed to be the first report of a patient with severe acute brain injury in whom serial clinical and physiological assessments allowed documentation of the reversibility of such a critical level of cerebral hypoperfusion.
