B-35. Changes in CSF Resorptive Capacity After Pneumoencephalography in Normal Pressure Hydrocephalus

We demonstrated that the capacity of the cerebrospinal fluid absorption is disturbed by the instillartion of air in ventricles,and we believe that pneumoencephalography in patients with normal prssure hydrocephalus may result in reduction in the potential resorptive capacity of the ventricular fluid by air.
