    Abstract:
    BACKGROUND: Preterm infants with progressive post-hemorrhagic ventricular dilatation (PHVD) in the absence of associated parenchymal lesions may have a normal neurodevelopmental outcome. OBJECTIVES: To evaluate neurodevelopmental and cognitive outcomes among preterm infants with severe intraventricular hemorrhage (IVH) and PHVD requiring neurosurgical intervention. METHODS: 32 preterm infants were admitted to a neonatal intensive care unit with PHVD requiring neurosurgical intervention, and were seen in the follow-up clinic for standardized cognitive, behavioral and neurological assessments between 5 and 8 years of age. Only preterm infants with a gestational age (GA) of <30 weeks, as well as preterm and full-term infants with PHVD and full-term infants with perinatal asphyxia are seen in our follow-up clinic at this age. There were 23 infants with a GA of <30 weeks in this study population. For these 23, matched controls were available and compared with the IVH group. RESULTS: The majority (59.4%) had no impairments. None of the children with grade III and 8 of the 15 children (53%) with grade IV hemorrhage developed cerebral palsy. More subtle motor problems assessed with the Movement-ABC score were seen in 39% (n = 9); the mean IQ of all children was 93.4, and 29% of the children had an IQ of <85 (-1 SD). Timing of intervention did not have a beneficial effect on outcome. With respect to cognition, no significant differences were found between the IVH and the control group. CONCLUSION: The majority of the children in our population had no impairments. Cerebral palsy was not seen in any of the infants with a grade III hemorrhage.
