| Abstract: | Cranial ultrasound examinations were performed on 533 infants of between 48 and 96 hours of age to establish the range of ventricular size in neonates of different gestational ages in whom there was no evidence of intraventricular hemorrhage or neural tube defects. It was found that ventricular size did not vary in infants with gestational age of 26 weeks or more. Only 15 (2.8 per cent) neonates had a ventricular width of greater than 3 mm. Of these 15 infants, 13 were re-examined within the first year of life and found to be neurologically and developmentally normal. |
