Abstract Analysis of cerebrospinal fluid pulse pressure was reported to be useful in the assessment of the cerebrospinal pressure-volume compensation. The method for the estimation of high-frequency centroid (HFC) was modified and used to verify the correlation between HFC and other compensatory parameters investigated by means of the lumbar infusion test in 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 also demonstrated that HFC decreased dynamically during the infusion test. Ausführliche Beschreibung
