Abstract

Several investigators (Marmarou, 1975; Avezaat and Van Eijndhoven, 1984) have indicated that the CSF pulse pressure (ΔPcsf) is related to intracranial compliance. Anile in our laboratory (unpublished data) found that ΔPcsf was not related to compliance. If mean CSF pressure (Pcsf) was kept constant, ΔPcsf and the slope of ΔPcsf vs. Pcsf was the same regardless of whether the skull was open or closed. However, compliance, as measured by the volume-pressure test, changed.
