Cerebral circulation after head injury. Part 4: Functional anatomy and boundary-zone flow deprivation in the first week of traumatic coma.


A considerable body of evidence suggests that posttraumatic disturbances of the cerebral circulation contribute to poor neurological outcome after blunt head injury, especially when regional cerebral blood flow (rCBF) falls to the ischemic range (below 17 ml/100 gm/min). Cerebral infarction concentrated in the arterial boundary regions has been described in… (More)
