Outcome of high-risk neonates with ventriculomegaly
Insights
Many infants with moderate ventriculomegaly show spontaneous improvement and normal development. However, larger ventricular size correlated with lower developmental scores, indicating potential cognitive and psychomotor effects.
Area of Science:
- Pediatric Neurology
- Developmental Neuroscience
- Neuroradiology
Background:
- Ventriculomegaly, an enlargement of the brain's ventricles, is a common finding in infants.
- The long-term neurodevelopmental outcomes for infants with ventriculomegaly require further investigation.
Purpose of the Study:
- To assess the neurodevelopmental outcomes of infants with ventriculomegaly.
- To determine the relationship between ventricular size and developmental trajectory.
Main Methods:
- Evaluation of 89 infants with computed tomography (CT) head scans.
- Minimum follow-up period of one year for developmental assessment.
Main Results:
- Spontaneous stabilization or regression of moderate ventriculomegaly observed in a significant proportion of cases.
- High percentage of infants achieved normal developmental outcomes.
- Statistically significant trend of lower developmental scores with increasing ventricular size.
Conclusions:
- Many infants with ventricular enlargement do not progress to hydrocephalus.
- Cognitive and psychomotor development may be adversely affected by the degree of ventricular enlargement.
Abstract:
The authors evaluated 89 infants who had had computed tomography of the head and who were followed-up for a minimum of one year. In a large proportion with moderate ventriculomegaly spontaneous stabilization or regression occurred, with normal developmental outcome in a high percentage of cases. However, there was a statistically significant trend toward lower developmental scores as ventricular size increased. Many infants with ventricular enlargement will not develop progressive hydrocephalus, but their cognitive and psychomotor development may be affected.
