A 34-year-old woman, who had a history of five spontaneous losses and failures of two McDonald purse-string cerclages, underwent a transabdominal cervico-isthmic cerclage (TCC). She became pregnant 17 months after TCC. At 35 weeks of gestation, she was admitted to our hospital due to preterm labor and delivered a healthy female baby (2270 g) by cesarean section. After delivery of the newborn infant, we found a migration of about one third of the cerclage band into the endocervical canal. Two years later, she had one further pregnancy, reached 33 weeks of gestation, and delivered a 1450 g male baby by cesarean section due to a preterm labor without any signs of infection. Although it could have been a case of pure coincidence, we take a chance to speculate that the migration of the cerclage band into the endocervical canal might have been the reason for the preterm labor, and it must have been removed at her first cesarean section and replaced by a new cerclage band for her next pregnancy.
一名34岁女性，有5次自然流产史，两次麦克唐纳荷包缝扎宫颈环扎术失败，接受了经腹宫颈峡部环扎术（TCC）。TCC术后17个月她怀孕了。妊娠35周时，因早产入住我院，剖宫产分娩出一名健康女婴（2270克）。新生儿分娩后，我们发现约三分之一的环扎带移入宫颈管内。两年后，她再次怀孕，妊娠33周时，因早产且无任何感染迹象行剖宫产分娩出一名1450克男婴。尽管这可能纯属巧合，但我们还是冒昧推测环扎带移入宫颈管内可能是早产的原因，并且在她首次剖宫产时必须将其取出，并在下次怀孕时更换新的环扎带。
