Abstract
Head growth velocity was assessed weekly during the neonatal period and at 3 month intervals up to one year of corrected age (CA) in 47 premature infants whose clinical data is shown below (mean ± SEM):
During the neonatal period head growth velocity in controls (Gr. 0) and in infants with grade 1, 2, and 3 IVH were comparable but below intrauterine standards (0.76 cm/week). Infants with grade 4 IVH had significantly higher head growth rates than all other groups (0.84 cm/week, p < 0.05). The neonatal pattern of head growth in infants with grade 4 IVH was not uniform: 2 of these infants (shunted) exhibited head growth above the 90%ile, while 1 infant (shunted) had head growth below the 3%ile and 3 infants (1 shunted) demonstrated head growth within normal percentiles. At follow-up the same patterns in head growth established during the neonatal period persisted up to year of CA. However, at that time, the head growth velocity in infants with grade 4 IVH was no longer significantly different. This study demonstrates that in the absence of grade 4 IVH there is not detectable adverse effect of IVH on head growth velocity of premature infants up to one year of corrected age.
