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 perivemtricular
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.
