宫颈环扎术治疗宫颈机能不全妊娠结局

目的探讨宫颈环扎术治疗宫颈机能不全的不同手术时间、手术时机的临床效果及妊娠结局。方法回顾性分析2005年5月至2009年10月22例因宫颈机能不全行宫颈环扎术患者的不同手术时间、手术时机的临床效果及妊娠结局。结果①妊娠12～16周组13例与妊娠17～28周组9例行宫颈环扎术,两组流产、早产、足月产率比较,差异均有统计学意义(P0.05);②紧急宫颈环扎术组8例与择期宫颈环扎术组14例,流产、早产、足月产率比较差异均有统计学意义(P0.05)。结论对有宫颈机能不全者,应在妊娠14～16周择期行宫颈环扎术;对孕前未能诊断宫颈机能不全者,有晚期流产史或早产史的高危孕妇孕中期B超发现宫颈机能不全,行紧急宫颈环扎术,术后加强监测、防止感染亦能取得一定临床效果,降低晚期流产率及早产率。

The clinical investigation for cervical cerclage on pregnancy outome of cervical incompetence

Objective To analyze the clinical effect of cervical cerclage on different operation time and pregnancy outcome.Methods Twenty-two patients who had performed cervical cerclage for cervical incompetence from May 2005 to October 2009,were carried out a retrospective analysis for operation timing and pregnancy outcome.Results ①Significant statistical significance is obtained in late abortion rates and term birth rates between 12-16 gestational weeks group（13 cases）and 17-28 gestational weeks group（9 cases）（P0.05）;②Significant statistical significance is obtained in late abortion rates and term birth rates between emergent cervical cerclage group（8 cases）and selective cervical cerclage group（14 cases）（P0.05）.Conclusion We need to give the cervical cerclage in 14-16 gestational weeks to the cervical incompetence patients;For some high risk gravida who have late abortion or premature,but haven＇t diagnosed with cervical incompetence,could accepte emergent cervical cerclage and strengthen monitoring,which can reduce the late abortion and premature rates.
