Abstract
We compared the neurodevelopmental outcomes of infants with and without a periventricular
venous hemorrhagic infarction (PVHI). The study was designed as a case–control study.
The primary outcome measure was any score of < 85 in at least one of the cognition,
language, or motor domains of the Bayley Scales of Infant and Toddler Development-3rd
edition (Bayley-III) at 18 to 24 months corrected age. Of 41 infants identified, 20
index infants were matched with 40 controls for analyses. No differences in the primary
outcome were noted between the two groups of infants, 52.9% with PVHI compared with
62.5% without PVHI (OR: 0.68, 95% CI: 0.21–2.13; p = 0.56). Infants with a PVHI were likely to have cerebral palsy, 85% compared with
7.5%, with the majority (70%) being ambulatory. Infants with a PVHI were developmentally
similar to their preterm counterparts as it related to cognition and language.
