探讨经阴道彩超和宫颈环扎术在宫颈机能不全诊治中的应用价值.[方法]选取2014年6月至2016年7月在本院诊治的127例宫颈机能不全高危患者,自孕12周开始行经阴道超声检查,测量评估颈管长度,每间隔2周检查1次,颈管长度25~30mm,且宫颈内口扩张显示为U型或V型则接受相应治疗,其余从研究中剔除.将符合上述要求的86例宫颈机能不全患者按照随机数表法分为观察组与对照组,每组43例.对照组口服地屈孕酮治疗,观察组予以宫颈环扎术治疗.比较两组妊娠结局(流产、早产、足月妊娠)、妊娠周期、新生儿基本情况(体质量、出生后监测时间、Apgar评分)及治疗期间安全性.[结果]观察组流产率、早产率显著低于对照组;足月妊娠率显著高于对照组(P<0.05);观察组妊娠周期长于对照组(P<0.05);观察组新生儿体质量及出生后Apgar评分高于对照组,出生后监测时间短于对照组(P0.05).[结论]经阴道彩超检查有利于早期发现宫颈机能不全,使患者及时接受治疗,且宫颈环扎术可有效延长妊娠周期,降低流产、早产发生率,改善妊娠结局,同时该治疗方案安全性高,值得临床推广应用.“,”ToexplorethevalueoftransvaginalcolorDopplerultrasoundandcervicalcerclage inthediagnosisandtreatmentofcervicalincompetence.[Methods]FromJune2014toJuly2016,127high-risk patientswithcervicalinsufficiencyinourhospitalwereexaminedbytransvaginalultrasonographyfrom 12 weeksofpregnancy.Thelengthofcervicalcanalwas measuredandevaluatedonceeverytwo weeks.The lengthofcervicalcanalwas25-30 mm,andthedilatationofcervicalinternalorificeshowedasU-typeorV-typewastreatedaccordingly.Therestwereexcludedfromthestudy.86patientswithcervicalinsufficiency weredividedintoobservationgroupandcontrolgroupaccordingtorandomnumbertablemethod,43casesin eachgroup.Thecontrolgroupwastreatedwithdidrogesteroneorally,whiletheobservationgroupwastreated withcervicalcerclage.Pregnancyoutcomes (abortion,prematuredelivery,full-term pregnancy),pregnancy cycle,basicconditionofnewborn (bodyweight,postnatalmonitoringtime,Apgarscore)andsafetyduring treatmentwerecomparedbetweenthetwogroups.[Results]Theabortionrateandprematuredeliveryratein theobservationgroupweresignificantlylowerthanthoseinthecontrolgroup;thefull-term pregnancyrate wassignificantlyhigherthanthoseinthecontrolgroup (P<0.05);thepregnancycycleintheobservation groupwaslongerthanthatinthecontrolgroup (P<0.05);theneonatalweightandApgarscoreintheob-servationgroupwerehigherthanthoseinthecontrolgroup,andthemonitoringtimeafterbirthwasshorter thanthatinthecontrolgroup(P0.05).[Conclusion]TransvaginalcolorDoppler ultrasoundexaminationisconducivetoearlydetectionofcervicalinsufficiencyandtimelytreatmentofpatients.
