Telemetric Monitoring of Intracranial Pressure
Background: We present the application of a modern telemetric method that records and monitors Intracranial Pressure (ICP) over long periods in patients with possible intracranial hypertension.
Methods: A telemetric devise (Raumedic, Neurovent P-tel) was surgically implanted in six (6) patients. Three (3) patients with inconclusive diagnosis of idiopathic intracranial hypertension, two (2) patients with possible diagnosis of aqueduct stenosis and one (1) patient with Normal Pressure Hydrocephalus. All patients underwent a 3-day ICP recording within the nursing unit. Two more recordings were obtained over a period of 2-6 months at outpatient base.
Results: All patients had an uncomplicated post-operative course. Analysis of the data excluded the diagnosis of idiopathic intracranial hypertension in two patients. Contrary in four patients data confirmed elevated ICP values and subsequently three of them underwent shunts implantation, while one patient refused further neurosurgical treatment.
Conclusions: The telemetric device could be safely implanted in selected patients. It could provide long-term ICP recordings, which are necessary to confirm diagnosis and guide to the appropriate treatment.
