    Purpose: Our aim was to evaluate if optical coherence tomography (OCT) can be used as an alternative for fundoscopy to screen for increased intracranial pressure (ICP) in children with craniosynostosis Methods: We performed a prospective cohort study at the Dutch Craniofacial Centre. We included...

    Background. In patients with supratentorial tumours, intracranial pressure is a strong predictor of intra-operative brain swelling and thresholds for ICP associated with brain swelling have been defined. Whether these ICP thresholds can be applied during infratentorial surgery is uncertain. We...

    Background: Advantages of telemetric devices for long-term intracranial pressure (ICP) measurement have been mentioned several times in the literature. However, descriptions of associated complications are lacking. Therefore, the presented observational study focused on clinical and radiological...

    Elevated intracranial intravenous pressure is not routinely measured in clinical practice. Indirect evidence of increased venous pressure is reflected in the size change of the cerebral sinuses and the presence of venous infarctions. The purpose of this study is to evaluate the role of brain...
