Poor perinatal outcome associated with vasa previa: is it preventable? A report of three cases and review of the literature

Abstract

We describe three cases of vasa previa and review the English-language literature for all cases reported since 1980. Antenatal diagnosis was significantly associated with decreased fetal mortality (p = 0.033). A low-lying placenta is a risk factor for vasa previa, as it occurred in 81% of patients.
