Lumbar Pressure Monitoring with a New Fiberoptic Catheter
The syndrome of progressive dementia, gait disturbance, hydrocephalus and normal intracranial pressure is usually termed normal-pressure hydrocephalus (NPH). Since the initial reports of good results of shunting cerebrospinal fluid (CSF) in these patients, interest has been aimed at selection of patients for shunting. Continuous pressure recording in the investigation of hydrocephalus has gained increasing attention and especially the occurrence of B-waves can be of interest (Børgesen and Gjerris, 1982). Long-term pressure monitoring has so far been restricted to techniques for intracranial pressure-monitoring, usually involving some minor surgical procedure.
