Expectant management of partial placental abruption in previable pregnancies. A report of two cases.

Placental abruption is a major cause of perinatal morbidity and mortality, especially in the preterm infant. Two patients had previable pregnancies complicated by placental abruption and large extraamniotic hematomas. Precise diagnosis and follow-up with real-time ultrasound allowed expectant management until the delivery of viable infants became possible.
