Summary
Neonatal middle cerebral artery infarction subtypes were defined, with truncal infarction being more common. Primary motor cortex involvement on neonatal ultrasonography can predict severe motor hemisyndrome.
Area of Science:
- Neonatal neurology
- Pediatric neuroimaging
- Cerebrovascular diseases
Background:
- Neonatal pial middle cerebral artery infarction is a significant cause of neurological deficits.
- Accurate classification of infarction subtypes is crucial for understanding outcomes.
Purpose of the Study:
- To define neonatal pial middle cerebral artery infarction.
- To characterize subtypes of cortical middle cerebral artery infarction.
Main Methods:
- Retrospective analysis of neonates with focal arterial infarction detected via ultrasonography.
- Detailed subtyping of cortical middle cerebral artery infarction.
Main Results:
- Forty middle cerebral artery infarctions were identified over 10 years, with truncal type (n=13) more common than complete (n=5).
- Primary motor cortex involvement predicted severe motor hemisyndrome.
- Clinical seizures occurred in less than half of patients with truncal infarction.
Conclusions:
- Differentiating between truncal and complete middle cerebral artery stroke is important for outcome prediction.
- Neonatal ultrasonography can predict severe motor hemisyndrome based on primary motor cortex involvement.
- Asphyxia is an uncommon cause of focal arterial infarction.
