Measurement of ICP (Intracranial Pressure) in the Brain

The continuous measurement of the ICP (intracranial pressure) is an invasive procedure used to determine the pressure inside the cranium.

Indications of ICP Measurement

Due to the limited expansion capabilities of the brain because of the firm cranium, the ICP increases inside the cranium as the volume increases. Therefore, a precise monitoring of the pressure in the inside of the cranium is very important, because the clinical symptoms are initially unspecific. Indications for measuring the ICP are:

  • Severe craniocerebral injury
  • Significant subarachnoid bleeding
  • Tumors
  • Strokes
  • Hydrocephalus

  • Intraparenchyma and intraventricular cranial bleedings
  • Severe meningitis
  • For all polytraumatized patients
  • For all coma patients with unknown etiology

ICP Measuring Locations

The ICP (intracranial pressure) can be measured at different locations in the brain.

For measuring ICP in the parenchyma, the NEUROVENT-P catheter measures the pressure directly in the brain tissue.

Various types of ventricular catheters are available for direct measurement of pressure in the ventricles. Due to the additional drainage function of the NEUROVENT catheter, excess CSF (cerebrospinal fluid) is drained from the ventricles. The elevated ICP is also lowered by draining the CSF. Implantation of ventricular catheters is facilitated by various application tools such as a stylet or a guide wire. The NEUROVENT-Sleeve Housing is an unique design which incorporates ICP measurement in the parenchyma and CSF drainage in the ventricle.
