[Results of cerebral sonography in children with myelomeningoceles]
Insights
Early ultrasound in infants with myelomeningocele can predict hydrocephalus development. A Chiari syndrome diagnosis via sonography in these infants indicates a higher likelihood of needing a shunt.
Area of Science:
- Pediatric Neurosurgery
- Medical Imaging
- Developmental Biology
Context:
- Myelomeningocele, a severe birth defect, often leads to hydrocephalus, requiring timely intervention.
- Post-surgical monitoring of infants with myelomeningocele is crucial for detecting complications like hydrocephalus.
- Understanding the morphological characteristics of the ventricular system aids in differentiating hydrocephalus origins.
Purpose:
- To assess the utility of early ultrasound in diagnosing hydrocephalus in infants post-myelomeningocele repair.
- To compare ventricular system morphology in hydrocephalic infants with myelomeningocele against other hydrocephalus etiologies, particularly Chiari syndrome.
- To evaluate the prognostic value of initial sonographic findings for hydrocephalus development.
Summary:
- Forty-seven infants with myelomeningocele underwent ultrasound post-surgical closure and were followed for 12 months.
- Of 31 infants requiring shunts due to progressive ventricular dilatation and increased intracranial pressure, 81% showed Chiari syndrome on ultrasound.
- Conversely, only 31% of 16 infants not requiring shunts presented with Chiari syndrome, suggesting early sonography's prognostic role.
Impact:
- Initial sonographic examination provides valuable prognostic information for hydrocephalus development in infants with myelomeningocele.
- This study aids in the early identification of infants at higher risk for shunt dependency.
- Findings can refine clinical management strategies and improve outcomes for pediatric patients with myelomeningocele.
Abstract:
47 infants with myelomeningocele were investigated by ultrasound after the surgical closure of the cele and followed up to 12 months. The aim was the early diagnosis of hydrocephalus and the recording of morphological features of the ventricular system in comparison with hydrocephali of other origins, especially of Chiari-Syndrome. 31 infants needed a shunt due to rapid progress of the ventricular dilatation and clinical signs of a raised intracranial pressure: in 25 of this group (81%) the ultrasound investigation demonstrated a Chiari-Syndrome. Of 16 further infants who definitely did not need a shunt, only 5 (31%) had a Chiari-Syndrome. Therefore, the first sonographic examination seems to provide a certain prognostic evidence for the development of a hydrocephalus.
