BACKGROUND: The management of post-hemorrhagic hydrocephalus remains a discussion. We describe the neurodevelopmental outcome at the corrected age of 12 and 24 months of infants with PHVD treated with high-threshold therapy. OBJECTIVE: To describe, and compare the neurodevelopmental outcome of a cohort of premature infants with grade III or IV intraventricular hemorrhage with or without development of PHVD. METHODS: Retrospective chart and image review of all IVH grade III and IV infants admitted to the department of Neonatology of the Academic Medical Center, Amsterdam, the Netherlands between January 1999 and December 2006. A standardized neurodevelopmental examination was performed at the corrected ages of 12 and 24 months. RESULTS: In total, 118 cases with IVH were identified. IVH grade III: n = 63, mean gestational age (GA): 28 weeks (SD 2.3), median birth weight (BW): 1130 g (range 908-1460 g); IVH IV: n = 31, mean GA: 28 weeks (SD 2.4), median BW: 1105 g (range 925-1230 g). Grade III and IV cases developed PHVD in 75% versus 42% respectively. Abnormal outcome in IVH III patients mainly occurred in cases with PHVD (12 months: 47% abnormal, 24 months: 64% abnormal). In the IVH IV cases, outcome was comparable with or without PHVD. Developmental delay was more pronounced at 24 months. CONCLUSION: Mainly IVH III cases developed PHVD. Comparing our results with the literature neurodevelopmental outcome was poorer with our high-threshold therapy.
