  "account": "Twins born over a 101-day interval represent a rare occurrence, according to Turkish medical researchers who documented such a case in 2012. Following in vitro fertilization, the mother experienced regular contractions at 21 weeks gestation. By this time, the cervix was dilated to 8 centimeters and 80 percent effaced, with the amniotic sac broken. The first twin was delivered shortly afterward, weighing just 610 grams and showing no signs of life.\n\nTo give the second twin a chance to develop further, doctors took extraordinary measures. They performed a McDonald cerclage, a surgical stitch to reinforce the cervix, and administered anti-contraction drugs, broad-spectrum antibiotics, and corticosteroids. Continuous monitoring of both mother and fetus was maintained throughout the extended pregnancy. The mother remained hospitalized until 28 weeks gestation, during which she was treated with the contraction-suppressing medication nifedipine until 34 weeks.\n\nHowever, by 36 weeks, contractions resumed and the second twin was delivered via cesarean section due to its breech presentation. The boy weighed an impressive 3,639 grams and had an Apgar score of 9 at one minute, indicating good health in the neonatal period. Remarkably, the interval between the two deliveries amounted to 101 days.\n\nWhile this Turkish case demonstrates the potential benefits of delayed-interval delivery, outcomes remain highly variable. A 2017 systematic review of 128 cases across 13 studies found that the second-born twin had a significantly lower mortality risk compared to the first twin. However, the authors cautioned that the evidence is based on observational reports, with management varying widely between individual cases and no standardized protocol in place.\n\nA similar 2020 multicenter study evaluated 13 delayed-interval deliveries across four major perinatal centers in Paris between 2005 and 2018. The study found that the first twin was delivered at a median gestational age of 18 weeks, while the second twin was delivered at a median of 25 weeks and three days. Delays between the two deliveries ranged from 13 to 138 days, with seven out of the 13 second-born twins surviving. The study also documented several severe maternal complications, including chorioamnionitis—a bacterial infection of the fetal membranes—and disseminated intravascular coagulation, a dangerous blood-clotting disorder.\n\nThese findings underscore both the potential survival benefits and the significant clinical risks associated with attempting to extend a twin pregnancy after the first twin is delivered. Cervical cerclage, one of the interventions doctors may consider, remains a controversial topic. A 2024 scoping review of 22 studies examining emergency cervical cerclage in delayed-interval twin deliveries found that pregnancies treated with cerclage tended to have longer intervals between deliveries, although the evidence is observational and no standardized protocol exists.\n\nOther treatments commonly employed in delayed-interval delivery cases include antibiotics, medications to suppress uterine contractions, and drugs to promote fetal lung maturation. Close monitoring of both the mother and the remaining fetus is essential to detect signs of infection, labor, or other complications.\n\nUltimately, the decision to attempt delayed delivery depends on a myriad of factors, including the mother's general health, the condition of the remaining fetus, and the circumstances surrounding the initial delivery. Given the largely anecdotal nature of the evidence to date, doctors must carefully weigh the potential benefits of gaining additional gestational time against the inherent risks to both mother and fetus.",
  "summary": "Twins are usually born minutes or hours apart, but in rare cases doctors can deliver one baby and delay the birth of the second for days or even weeks. The procedure, known as delayed-interval delivery, aims to give the remaining fetus more x|time to develop inside the uterus after the first twin has been born […]",
