Non-Invasive ICP-Monitoring in Childhood Hydrocephalus: A Comparison Between Anterior Fontanelle Pressure and Transcranial Doppler
The ability to discriminate between ventriculomegaly and progressive hydrocephalus often relies on clinical assesment of increasing head circumference, developmental deficits and a change in ventricular size and configuration. Some patients with slowly progressive hydrocephalus cannot be detected adequately with the methods currently in use for monitoring hydrocephalus. Previous studies have demonstrated that the resistance index  (RI) or pulsatility index  (PI) are useful indicators of increased intracranial pressure (ICP) and the need for a shunt. Shunt dysfunction was correlated with elevated RI’s . In none of these studies the variables were related to the actual ICP.
