Influence of sex and disease etiology on the development of papilledema and optic nerve sheath extension in the setting of intracranial pressure elevation in children.

Introduction: Dilatation of the optic nerve sheath diameter and swelling of the optic disc are known phenomena associated with intracranial pressure elevation.

Research Question: Do sex and disease etiology have an impact on the development of optic disc elevation and optic nerve sheath extension in children in the setting of ICP elevation? Fundoscopic papilledema and point-of-care-ultrasound techniques-optic nerve sheath diameter (US-ONSD) and optic disc elevation (US-ODE) - were compared in this regard.

Material And Methods: 72 children were included in this prospective study; 50 with proven pathology (e.

Ultrasound-guided initial diagnosis and follow-up of pediatric idiopathic intracranial hypertension.

Background: Idiopathic intracranial hypertension in children often presents with non-specific symptoms found in conditions such as hydrocephalus. For definite diagnosis, invasive intracranial pressure measurement is usually required. Ultrasound (US) of the optic nerve sheath diameter provides a non-invasive method to assess intracranial pressure.

Non-Invasive Quantitative Approximation of Intracranial Pressure in Pediatric Idiopathic Intracranial Hypertension Based on Point-of-Care Ultrasound of the Optic Nerve Sheath Diameter.

Background: To investigate whether ultrasound-based optic nerve sheath diameter (US-ONSD) is a reliable measure to follow up children with idiopathic intracranial hypertension (IIH). In addition, to analyze the inter- and intra-individual relationships between US-ONSD and intracranial pressure (ICP), and to investigate whether an individualized mathematical regression equation obtained from two paired US-ONSD/ICP values can be used to approximate ICP from US-ONSD values.

Methods: 159 US examinations and 53 invasive ICP measures via lumbar puncture (LP) were performed in 28 children with IIH.

Intracranial Pressure, Autoregulation, and Cerebral Perfusion in Infants With Nonsyndromic Craniosynostosis at the Time of Surgical Correction.

Background And Objective: Although an increased intracranial pressure (ICP) is a known problem in children with syndromic craniosynostosis, it remains unclear whether elevated ICP and impaired cerebral perfusion exist in nonsyndromic synostosis and should be defined as targets of primary treatment. This study aimed to investigate ICP, cerebral autoregulation (CAR), and brain perfusion in infants with nonsyndromic craniosynostosis at first surgical intervention.

Methods: Forty-three infants were prospectively included.

Transorbital point-of-care ultrasound versus fundoscopic papilledema to support treatment indication for potentially elevated intracranial pressure in children.

Purpose: To compare transorbital point-of-care ultrasound techniques -optic nerve sheath diameter (US-ONSD) and optic disc elevation (US-ODE)- with fundoscopic papilledema to detect potentially raised intracranial pressure (ICP) with treatment indication in children.

Methods: In a prospective study, 72 symptomatic children were included, 50 with later proven disease associated with raised ICP (e.g.
