Abstract |
Purpose : Recent progress in neonatal medicine increased the survival of preterm low birth weight infants. However, neurodevelopmental sequelae are ever increasing. We carried out this study to determine whether serial cranial ultrasonographic findings could predict neurodevelopmental outcome.
Methods : Four hundred and forty-one preterm low birth weight infants, who were admitted to the Neonatal Intensive Care Unit of Chonnam University Hospital from Jan. 1996 to Dec. 1998, were enrolled in this study. Infants were allocated to one of four groups, according to their ultrasonographic findings. Cases were included in group I when they showed normal ultrasound scans or their periventricular echogenicity was equal to choroid plexus(n=232); in group II, subependymal hemorrhage, intraventricular hemorrhage without ventricular dilatation(n=146); in Group III, intraventricular hemorrhage with ventricular dilatation or periverntricular echogenicity-3 (n=48); in Group IV, bilateral cystic Periventricular leukomalacia(PVL)(n=15). In these four groups, correlation among the incidence of cerebral palsy and neurodevelopmental abnormalities, cranial ultrasonographic findings, and other perinatal parameters were evaluated by ANOVA test, chi- square test, and logistic regression analysis.
Results : The incidence of cerebral palsy was remarkably high in group IV(86.6%) and half of them showed a combination of other developmental abnormalities. The significant predictors of cerebral palsy were cystic PVL and duration of oxygen therapy.
Conclusion : Cranial ultrasonographic findings could predict the development of cerebral palsy and other neurodevelopmental outcome in preterm low birth weight infants. |
