Pregnancy following placental abruption.

The aim of the present study by a retrospective chart review was to examine the recurrence rate after placental abruption. Between 1985 and 1998, 81 patients had a placental abruption. We had 2-year follow-up information about 31 patients and 27 of them had a total of 34 subsequent pregnancies. Recurrent placental abruption was observed in 6 pregnancies in 6 patients (6/27, 22.2%). Of the 6 recurrent placental abruptions, the gestational age was 1-3 weeks earlier than that of previous abruption in 4 patients. One patient delivered a healthy baby after her first abruption and then experienced a second abruption. We conclude that careful management is needed after 30 weeks in pregnant women with a previous history of placental abruption.
