Optimization of diagnosis and management protocols has potential to improve maternal, fetal and postnatal outcomes.All women with placenta previa or low-lying placenta have an increased risk of a morbidly adherent placenta, particularly those who have had a prior cesarean delivery (strong/moderate).In women with placenta previa or a low-lying placenta, presence of a marginal/velamentous cord insertion close to the cervical os or a succenturiate placental lobe increases the risk of vasa previa (strong/moderate).History of antepartum hemorrhage (first episode <29 weeks or recurrent episodes [≥3]), a thick placental edge covering (or close to) the cervical os, short cervical length (<3 cm with placenta previa, <2 cm with low-lying placenta), and a previous cesarean delivery are risk factors with an associated increased risk of urgent/preterm cesarean delivery (strong/moderate).In the absence of risk factors, outpatient management of women with placenta previa is safe (strong/moderate).Bed rest or reduced activity is not beneficial in women with placenta previa and can be potentially harmful.
