Gestational age at delivery is a critical factor influencing neonatal survival, with prematurity being a major contributor to increased neonatal morbidity and mortality. Twin pregnancies are particularly prone to preterm deliveries, and the second twin is generally expected to follow shortly after the first twin’s delivery. However, in certain cases, a delayed delivery of the second twin following the loss of the first twin can be considered, with some successful outcomes reported. This case report highlights a rare instance of a delayed interval delivery, wherein the second twin was carried to term following the spontaneous abortion of the first twin at 15 weeks gestational age. Cervical cerclage was performed as part of the management to prolong the pregnancy, resulting in the successful delivery of the second twin at term. This case contributes to the limited body of literature on successful delayed delivery of the second twin and underscores the potential for positive outcomes even in complex and high-risk scenarios. The management approach and outcome offer valuable insights into the possibilities of prolonging pregnancy in cases of twin loss and the potential role of cervical cerclage in achieving a successful outcome.
