In multiple pregnancies with threatened premature delivery or preterm premature rupture of membranes (pPROM) of a single sac, prolonging pregnancy after the delivery of the first baby may improve the chances of survival of the second baby. We report the delayed delivery of a second baby in a twin pregnancy with pPROM and very premature delivery of the first baby. This condition is exceptional and there are no validated medical protocols for its management; the scientific evidence is still controversial. In our case, after the birth of the first baby, pregnancy was continued for 29 days, with monitoring of maternal and fetal parameters, which enabled the delivery of the second baby with improved neonatal outcomes. This case supports the prolongation of the pregnancy of the second twin.
在单绒毛膜多胎妊娠且有早产风险或胎膜早破（pPROM）的情况下，第一个胎儿娩出后延长妊娠时间可能会提高第二个胎儿的存活几率。我们报告了一例双胎妊娠合并pPROM且第一个胎儿极早产的病例，第二个胎儿延迟分娩。这种情况很罕见，目前尚无经过验证的医疗方案来处理；科学证据仍存在争议。在我们的病例中，第一个胎儿出生后，继续妊娠29天，同时监测母胎参数，这使得第二个胎儿得以娩出，新生儿结局得到改善。该病例支持延长第二个双胎的妊娠时间。
