Description

CT (computed tomography) scans in 53 infants whose 1 minute Apgar scores had been 5 or less were reviewed. Comparing the CT findings between the patients of low and high Apgar scores which are checked both at 1 and 5 minutes after delivery, it was confirmed that the 5 minute Apgar score, particularly, is a good predictor of future neurological sequelae of the infants in perinatal hypoxia. Intracranial hemorrhage on the early scans and cerebral atrophy on the follow-up scans were the majority of abnormalities. Between infants with and without neurological sequelae, periventricular hypodensity that may be responsible for future periventricular leucomalacia was quantitatively compared. Differences in absorption density between the two groups were, unexpectedly, not obvious. Usefulness of CT, on the other hand, in detection of intracranial hemorrhage should be emphasized.
