The management of pregnancies complicated by placenta previa is best addressed in terms of the clinical setting: asymptomatic women, women who are actively bleeding, and women who are stable after one or more episodes of active bleeding.
ASYMPTOMATIC PLACENTA PREVIA
The management goals in women with asymptomatic placenta previa are to:
●Determine whether the previa resolves with increasing gestational age
●Reduce the risk of bleeding
●Reduce the risk of preterm birth
