摘要
目的探讨ART双胎妊娠患者中孕时宫颈长度及内口宽度对妊娠结局的影响。方法回顾性分析我院2006年1月至2010年11月在我院妇产科门诊产检的IVF术后双胎妊娠的孕妇的临床资料,其中正常分娩组共25例,早产组共30例,先兆早产组共23例,晚期流产组8例,分析其中孕宫颈长度与妊娠结局的关系。结果早产的发生与宫颈长度呈负相关,当宫颈长度<2.5cm时早产率显著增加;有宫颈内口扩张的患者来说易出现先兆早产或早产,当宫颈内口扩张>5mm者流产率及早产率明显增高,宫颈内口扩张<5mm者通过积极的保胎治疗后可有效延长孕周。结论 ART双胎妊娠患者孕中期的宫颈超声检查是必要的,积极有效的保胎治疗是降低晚期流产率和早产率重要手段。
Objective： To explore the cervical length in second trimester of ART twin pregnancy patients and its impact on pregnancy outcome.Methods： Retrospective analysis of 118 patients of ART twin pregnancy received examination in our hospital from January 2006 to December 2010.Among them 25 cases were normal delivery group,30 cases were preterm group,23 cases were threatened premature labor group and 8 cases were late abortion group.We compared the cervical length of different groups and analysied the relationship of the cervical length and pregnancy outcome.Results： The incidence of preterm birth was negatively correlated with cervical length and was significantly increased when the cervical length 2.5cm;The patients with dilated cervix more than 5mm were prone with threatened preterm labor or preterm birth.The patients with dilated cervix less than 5mm can effectively extend the gestational age by treating with aggressive tocolysis.Conclusions： It is necessary to get the cervical ultrasound examination of ART twin pregnancy in second trimester.The active and effective treatment is an important way to lower miscarriage rate of late abortion and premature delivery rates of ART twin pregnancy patients.
