Systematic screening for vasa previa at the 20?week anomaly scan

Introduction The presence of vasa previa carries a high risk for severe fetal morbidity and mortality due to bleeding caused by injury unprotected vessels when rupture membranes occurs. Previously, it has been shown that prenatal diagnosis significantly improves the outcome. However, systematic screening is not generally performed clinical studies demonstrating performance in routine practice are rare. objective this study was assess determining placental cord insertion at 20-week anomaly scan. Material methods This retrospective 6038 pregnant women between 18+0 24+0 gestational weeks who were prospectively screened depiction site Pregnancies with marginal or velamentous underwent vaginal sonography examination previa. In cases succenturiate bilobed placentas, bridging depicted, if necessary. Results There 21 all diagnosed prenatally. 18 cases, velamentous. remaining three had anomalies, which necessitated detailed examination.
