Objective: Periventricular hemorrhagic infarction (PVHI) is a major contributing factor to poor neurodevelopmental outcomes in preterm infants. We hypothesized that surviving infants with unilateral PVHI would have more favorable outcomes than those with bilateral PVHI.
Methods: This was a multicenter, retrospective study of infants who were admitted to 3 NICUs in North Carolina from 1998 to 2004.
