[Comparison of results of polygraphic sleep studies and cerebrospinal fluid pressure records in patients following removal of supratentorial expanding lesions].
In 4 patients operated upon for supratentorial brain tumors the authors carried out on the 3rd day after the operation polygraphic recording of nocturnal sleep with simultaneous measurements of cerebrospinal fluid pressure in the ventricular system by the method of Lundberg. A comparison of polygraphic records of nocturnal sleep with parallel measurements of intraventricular pressure demonstrated that all REM phases were associated with a rise in intraventricular pressure, while during phases 3 and 4 of sleep (NREM) the intraventricular pressure was always lower. In the remaining sleep phases 1,2 NREM and during episodes of nocturnal awakening no unequivocal consistencies were found.
