With delayed childbearing and increased use of ovulation-stimulating drugs and assisted reproductive technologies (ART), the incidence of multiple pregnancies has increased dramatically in the past 20 years. One of the most common and serious complications of multiple pregnancies is preterm delivery. The delivery of the initial fetus in a multiple gestation usually is followed by the delivery of the subsequent fetus or fetuses shortly there after. However, a few successful delayed-interval deliveries have been reported since the first case in 1880 by Carson. Since that time, an interest in delayed-interval delivery has been developed and spurred by the increased prevalence of multiple gestations and preterm deliveries associated with these pregnancies. We report a case of a delayed-interval delivery in a twin pregnancy with an interval of 71 days. This case is the longest interval case and the fisrt delayed-interval delivery in monochorionic twin in Korea.
