Prolongation of second twin’s delivery until term: A rare case of delayed-interval delivery

Abstract

Although some cases describing delayed birth of the second twin have been published recently, delay of delivery beyond 36 weeks seems scarce. We report a case of delayed-interval delivery wherein prolongation of the second twin’s delivery until term with a subsequent favorable infantile outcome. In this case, the stillbirth of the first twin occurred at 25 weeks’ gestation. Prophylactic tocolysis was performed with ritodrine and magnesium sulfate, and a McDonald cerclage was performed 2 days after delivery of the first twin. Ampicillin and gentamicin were also administered for the purpose of prevention of intrauterine infection. No clinical sign of chorioamnionitis was found thereafter, and full term uneventful delivery was achieved. With this experience, we believe that delayed-interval delivery can be effective in prolonging gestation and should be an option if the first twin developed an extreme preterm delivery.
