Abstract

Although shunt surgery is a generally accepted way of treating patients with NPH, there are only a few papers (Symon and Dorsch 1975) which report the changes in ICP after shunt. Without knowledge concerning ICP changes after shunt, we are apt to consider that the closing pressure of the shunt system which was installed was not low enough or that the patient was not a good candidate for the shunt surgery when it was not effective. In order to supplement the basic data, not only ICP changes but also changes in pressure volume index (PVI), outflow resistance (Rout) and the profile of B-waves after shunt were investigated.
