Association between maternal bleeding during gestation and congenital anomalies in the offspring

Abstract

The incidence of maternal bleeding complicating the pregnancies of 326 children examined at the Jerusalem Community Center for Child and Family Development is surveyed. A history of bleeding during pregnancy was more frequent in children with congenital anomalies of the central nervous system (and/or psychomotor retardation) (33 per cent) and in children with congenital anomalies of other systems (29 per cent) than in control children (12 per cent). The implications of these findings are discussed in relation to placental pathophysiology and the pathogenesis of threatened abortion.
