INTRODUCTION: Delayed delivery is sometimes performed in selected multifetal pregnancies when the first twin birth occurs inevitably. The aim of this procedure is to improve the prognosis and decrease the morbidity and mortality of the second twin. We report three cases of delayed-interval delivery of dichorionic-diamniotic twin pregnancies assisted in our center between 2015 and 2017. After the first twin delivery, the second twin was left in utero and the patient received tocolytic therapy and antibiotics. Cervical cerclage was not performed. RESULTS: Our patients were admitted between 21 + 3 and 23 + 6 weeks of gestation. We achieved an average interval delivery of 6.33 d. Four out of six twins did not survive the delayed interval procedure. The average stay of the first and second twins that were admitted to the neonatal intensive care unit (NICU) was of 72 d (28-116) and 39.5 d (12-67), respectively. The first twin birth was vaginal in all cases, while the second twin delivery was performed by cesarean section in two out of our three patients. Our neonatal results are not favorable, probably due to the extreme prematurity. CONCLUSIONS: Delayed delivery of the second twin before 28 weeks of gestation can be an alternative for the obstetrician since it could prolong the pregnancy until a gestational age which confers a better prognosis and a better perinatal outcome for the second twin.
