[Evaluation of cerebral blood flow in postoperative increased intracranial pressure].
In 20 patients with expanding intracranial lesions the intracranial pressure, cerebral blood flow, mean arterial blood pressure were determined and the cerebral perfusing pressure and cerebral vascular resistance were calculated before the operation and after removal of the expanding lesion. In 7 cases rises of the intracranial pressure occurred after the operation. In 5 of them they were associated with increased cerebral blood flow and decreased vascular cerebral resistance which was an evidence of their vasogenous mechanism. In 2 cases increased intracranial pressure was associated with raised cerebral vascular resistance suggesting oedema as the cause. The value of the investigations is discussed which give the results on which the choice of a proper management can be based in cases of increased intracranial pressure.
