Growth of preterm infants with cystic periventricular leukomalacia.

Etiology of the high rates of growth failure in children with cerebral palsy (CP) remains unclear. The purpose of this study was to evaluate the relation between growth failure in preterm infants with cystic periventricular leukomalacia (CPVL) and neonatal health complications. The population consisted of all preterm infants (51) with a gestational age of <33 weeks who were admitted to the Children's Hospital of Buffalo from 1988 to 1993 and who had CPVL. Out of the 41 survivors with CPVL who were followed, 39 developed CP and 18 developed growth failure during infancy. At the time of greatest growth failure, the majority (72%) of infants had signs of undernutrition as defined by the Waterlow (1972) classification. Oral feeding impairment was the sole risk factor for the occurrence of growth failure. Undernutrition appears to be important in the occurrence of growth failure in preterm infants with CPVL and CP.
