Abstract
Although recent advances in perinatal care have brought steady improvement in the mortality rates among small and critically ill preterm neonates, the incidence of major neurodevelopmental abnormalities in this population of patients has remained essentially unchanged over the past decade.1 Increasing attention, therefore, has been paid to early identification of infants, such as those with parenchymal involvement by intraventricular hemorrhage, who are believed to be at risk for later neurodevelopmental handicaps.Intraventricular hemorrhage, or hemorrhage into the germinal-matrix tissues with possible rupture into the ventricular system and parenchymal involvement of the developing cerebrum, remains a common problem in preterm neonates. . . .
