Relation between cerebral perfusion territories and location of cerebral infarcts.

abstract：BACKGROUND AND PURPOSE:The pressure-flow relation has been characterized in normal cerebrum, but it has not been studied in cerebrum dependent on collateral flow. The purpose of this investigation was to examine the relation between systemic pressure, regional cerebral blood flow, and middle cerebral artery branch pres...
