[Fluctuation of intracerebral pressure in various types of neurosurgical pathology].
During surgery and in the post-operative period fluctuations of the intracerebral pressure and in the dynamics of the local cerebral circulation were investigated in patients with a severe cerebro-cranial injury, acute apoplectic stroke and occlusive hydrocephalia. This was done by using a combined pressure sensor that simultaneously recorded the intracerebral pressure by the volemic method and the local cerebral blood flow-through hydrogen clearance. In patients exhibiting different degrees of hypertension three types of the intracerebral pressure fluctuations were recognized, differing both in their frequency and the amplitude. In some cases the local cerebral blood flow proved inversely proportional to the intracranial pressure.
