Analysis of cerebrospinal fluid pulse pressure was reported to be usef
ul in the assessment of the cerebrospinal pressure-volume compensation
. The method for the estimation of high-frequency centroid (HFC) was m
odified and used to verify the correlation between HFC and other compe
nsatory parameters investigated by means of the lumbar infusion test i
n 94 hydrocephalic children. The results confirm that in hydrocephalus
HFC is positively correlated to cerebrospinal elasticity coefficient,
but inversely to mean CSF pressure and pulse wave amplitude. It was a
lso demonstrated that HFC decreased dynamically during the infusion te
st.
