Carta S, et al. - The authors aim to determine survival and neurodevelopmental outcome of fetuses with prenatally detected isolated severe bilateral ventriculomegaly from published literature. Four-fifths of fetuses with severe ventriculomegaly survive. Of these, two-fifths show normal neurodevelopment. Overall, more than one-third of the total survive without handicap. Given that many cases undergo termination of pregnancy and the need for longer follow-up in order to detect subtle abnormalities, mortality and prevalence of developmental delay could be even higher than that reported in this paper.
