Group presentations at ICP2019 in Leuven, Belgium

Morten Andresen

The Copenhagen CSF Study Group unveiled several exciting research projects at the 17th meeting of the International Symposium on Intracranial Pressure and Neuromonitoring. It took place from September 8th to September 11th in Leuven, Belgium. The group had a strong showing with 7 participants.

The group participated with multiple projects. In the special interest session on hydrocephalus,

  1. MD, PhD-student Casper Riedel presented data from 4 approximated “normal” patients, with telemetric ICP-probes, indicating B-waves to possibly be a normal physiological phenomena closely related to apnea episodes during sleep.
  2. MD, Sarah Hornshøj Pedersen presented recent data on telemetric ICP monitoring in the pediatric patient and our experiences with the telemetric ICP-probe from Raumedic.

ICP signal analysis

MSc, PhD-student Isabel Martinez-Tejada presented our ongoing work related to different approaches to ICP signal analysis:

  1. B waves: a systematic review of terminology, characteristics, and analysis methods.
    Isabel Martinez-Tejada, Alexander Arum, Jens E. Wilhjelm, Marianne Juhler, and Morten Andresen.
  2. Empirical Mode Decomposition based method for artefact removal in raw ICP signals.
    Isabel Martinez-Tejada, Jens E. Wilhjelm, Marianne Juhler and Morten Andresen.

Physical head phantom

MSc Rikke von Barm, presented our initial prototype of a physical head phantom with the title “Physical Model for Investigating Intracranial Pressure with Clinical Pressure Sensors and Diagnostic Ultrasound - Preliminary Results” by Rikke von Barm, Isabel Martinez-Tejada, Marianne Juhler, Morten Andresen, and Jens E. Wilhjelm. The model is our first step towards obtaining an improved understanding of the ICP wave morphology and the associated tissue deformation around the pressure sensors during pressure application.

Our signal analysis and physical head phantom projects are the result of our fruitful collaboration with the Technical University of Denmark.

Optimal cerebral perfusion pressure

Based on his work as a visiting honorary researcher at Cambridge University, MD, PhD Alexander Lilja-Cyron presented the poster ‘Optimal cerebral perfusion pressure based on intracranial pressure derived indices of cerebrovascular reactivity – which one is better for outcome prediction in severe traumatic brain injury.’

Cape Town in 2022

The entire group is looking forward to renewed participation at the 18th ICP meeting planned for 2022 in Cape Town, South Africa.
