Abstract
A retrospective review was done of intracranial images obtained within the newborn period in 46 infants who had been treated with extracorporeal membrane oxygenation (ECMO). A neuroimaging score was determined on the basis of the extent and severity of findings on both ultrasound and computed tomographic scans. Presence of abnormality at neuroimaging and the neuroimaging score were correlated with the findings of neurodevelopmental evaluations (Bayley scales) performed in infants who were at a mean age of 11.8 months (range, 6-16 months). A significant inverse correlation was found between the neuroimaging score and mental and psychomotor development indexes of the Bayley scale (P < .005). Mean neuroimaging scores in infants with normal development were significantly lower than those in infants with delayed development (P = .002). Although individual outcomes cannot be predicted with neuroimaging, the neuroimaging score can be a useful adjunct in assigning patients who survive with ECMO treatment to risk categories for developmental outcome.
