This retrospective case-control study is aimed to extract predictors of preterm delivery after rescue cerclage.
We collected the data from all the pregnant women who underwent rescue cerclage before 26 gestational weeks at our facility between July 2006 and July 2016. These women were divided into "delivery at <34 weeks" group (n = 12) and "delivery at ≥34 weeks" group (n = 12). Multiple factors that had been detected at the time of cerclage were compared between these two groups.
"Gestational weeks at cerclage ≥23" and "positive vaginal culture at cerclage" were significantly more prevalent in the "delivery at <34 weeks" group than in the "delivery at ≥34 weeks" group. "Prolapsed membranes at cerclage" tended to be more prevalent in the "delivery at <34 weeks" group than in the "delivery at ≥34 weeks" group. "Positive vaginal culture at cerclage" was the only independent risk factor associated with eventual preterm delivery before 34 gestational weeks.
Simple aerobic bacterial culture of the vaginal swab sampled at the time of cerclage could be used as a reliable test to predict subsequent preterm delivery before 34 gestational weeks.
本回顾性病例对照研究旨在提取补救性宫颈环扎术后早产的预测因素。
我们收集了2006年7月至2016年7月期间在我院接受26孕周前补救性宫颈环扎术的所有孕妇的数据。这些孕妇被分为“34周前分娩”组（n = 12）和“34周及以后分娩”组（n = 12）。比较了两组在宫颈环扎时检测到的多个因素。
“宫颈环扎时孕周≥23周”和“宫颈环扎时阴道培养阳性”在“34周前分娩”组中比在“34周及以后分娩”组中更为普遍。“宫颈环扎时胎膜脱垂”在“34周前分娩”组中比在“34周及以后分娩”组中更倾向于更为普遍。“宫颈环扎时阴道培养阳性”是与34孕周前最终早产相关的唯一独立危险因素。
宫颈环扎时采集的阴道拭子进行简单需氧菌培养可作为预测34孕周前随后早产的可靠检测方法。
