Objective:
To report on pregnancy outcome in six twin pregnancies with delayed-interval delivery in a single maternal-fetal medicine practice.
Study Design:
All cases of attempted delayed-interval delivery from January 1988 to August 2000 in a single maternal-fetal medicine practice were retrospectively reviewed. Patients were managed with a treatment protocol that included rescue cerclage after delivery of the first born twin, antibiotics, corticosteroids and tocolysis.
Results:
Five of the six twin gestations resulted in viable birth of the second-born twin. One pregnancy had loss of both fetuses before viability. All first-born twins were nonviable. The median pregnancy prolongation achieved following delivery of the first-born, nonviable twin was 93 days, with a range of 23-153. Three of the five viable, second-born twins had a neonatal intensive care nursery stay of 3, 4 and 35 days (mean, 8.4). No infant required a ventilator.
Conclusion:
Based on our analysis of these six cases, the pregnancy prolongation gained resulted in a clinically significant benefit to the second-born twin, without significant morbidity in the mother.
