Cervical Cerclage at 17 Gestational Weeks for Delayed-Interval Delivery at 15 and 27 Weeks of Gestation in a Dichorionic Twin Pregnancy: A Case Report.

Delayed-interval delivery refers to the delivery of the remaining fetus(es) at least 24 h after the delivery of the first fetus. There have been limited case reports of delayed-interval deliveries in twin pregnancies whose delivery of the first twin occurred in the early second trimester. We report a delayed-interval delivery of a dichorionic diamniotic pregnancy complicated by multiple fibroids. A 38-year-old primipara woman delivered the first twin at 15 weeks and 3 days of gestation. She did not have uterine contractions or any signs of infection, then McDonald cerclage was performed at 17 weeks and 1 day of gestation. At 27 weeks and 2 days of gestation, the second twin, 922 g, was delivered by caesarean section after premature rupture of membranes. Delayed-interval delivery may be considered in the early second trimester if there is no evidence of uterine contractions or infection, even in patients at risk for preterm birth.
