Objective: ICP-guided valve adjustments are considered to be a promising therapy option in symptomatic shunt-treated patients. In this series, a shunt-integrated telemetric device was applied to objectify drainage-related problems and the influence of valve adjustments on the ICP and the clinical outcome.

Methods: Twenty-five patients with suboptimal shunt valve settings and drainage-related problems underwent insertion of telemetric ICP measurements (in average 7.3 measurements per patient) and consecutive valve adjustments (in average 3.4 adjustments per patient) were carried out. The relations between ICP, valve adjustment and the clinical outcome were statistically analyzed.

Results: In this series, 18 out of 25 patients benefited from ICP-guided valve adjustments. Clinical improvement was attributed to significant changes of the valve settings and the intracranial pressure. Therapeutic normalization of ICP was not automatically associated with clinical improvement. Valve settings determined ICP, but there was no direct correlation between pressure settings and ICP.

Conclusion: Telemetric intracranial pressure measurements in shunt-treated patients can be very helpful. Successful therapy of drainage-related problems is based on significant changes of the valve settings and the ICP.
