Parto diferido del segundo gemelo

The incidence of multiple pregnancies has increased in the last few years. Patients with multiple pregnancies are at risk of preterm delivery associated with high perinatal mortality and morbidity. Delivery of the first twin in a multiple gestation is usually followed by delivery of the second twin shortly thereafter. A prolonged interval between delivery of the fetuses in a multiple pregnancy is infrequent. We report seven cases of multiple pregnancies with delayed-interval delivery of the second twin. On the basis of our experience and a review of the literature, we conclude that delayed delivery of the second twin in very preterm gestational ages, with careful observation of fetal and maternal status, is recommended to improve survival and decrease morbidity in the second twin.
