Intracranial abnormalities were detected in 203(52%)of the 386 infants;73 (19%)hemorrhagic,86(22%)nonhemorrhagic,and 44(11%)combined lesions.Eighty- two lesions(21%)were classified as major.Forty-six(94%)of 49 major hemorrhages were identified at sonography.CT contributed additional information in 73%of neonates with intracranial abnormalities,of which 17 were major lesions not identified at sonography.The frequency of intracranial hemorrhage was increased in infants who were septic or premature or weighed less than 2.5 kg.An increase in time spent on ECMO bypass increased the risk for nonhemorrhagic injury.During an 8 year period,the frequency of hemorrhage and major nonhemorrhagic lesions remained constant,whereas minor nonhemorrhagic abnormalities increased significantly.Infants treated with ECMO continue to be at high risk for cerebrovascular injury.Although daily sonograms are useful in identifying major hemorrhages,followup CT scans are crucial for accurate evaluation of intracranial hemorrhages. |
