title: Hypoxic-ischemic brain damage in term neonates--the relation of neurodevelopmental handicap to cranial ultrasound findings.
abstract: This study presents ultrasound findings and neurodevelopmental follow-up in ten infants born at term suffering most severe grade of hypoxic-ischemic encephalopathy. Early ultrasound findings showed in nine of these ten neonates signs of cerebral edema accompanied in two children by intraventricular haemorrhage. Late ultrasound findings in all infants examined demonstrated severe cerebral atrophy, predominantly affecting the cortico-subcortical area. In three children multiple subcortical cysts were also present, corresponding to ultrasound findings of subcortical leukomalacia. Cranial computerized tomography was performed in six of the ten children, showing more precisely the predominant site of cortical atrophy, whereas in children with ultrasound findings of subcortical leukomalacia extensive low density areas in the subcortical white matter were present. All children had neurodevelopmental follow-up for between two and seven years. Six of the ten children have multiple disabilities suffering from spastic quadriparesis, epilepsy, mental retardation and/or visual disability. Among these six were all three children with subcortical leukomalacia. All the children demonstrated poor head growth and became markedly microcephalic. We consider ultrasonography to be very useful in the diagnosis of hypoxic-ischemic brain damage in term neonates as well in predicting the neurodevelopmental outcome in asphyxiated term infants.
