摘　　要：目的分析单胎及双胎妊娠的宫颈机能不全(CIC)患者经阴道行宫颈环扎术的妊娠结局,探讨不同的环扎时机对妊娠结局的影响。方法回顾性分析186例CIC患者的临床资料,根据是否经阴道行宫颈环扎术及环扎时机不同分为单胎紧急宫颈环扎组(30例)、单胎择期宫颈环扎组(120例)、单胎未行宫颈环扎组(孕24~28周存在宫口扩张,13例),双胎紧急宫颈环扎组(宫颈管长度<15 mm且宫口扩张,13例)、双胎择期宫颈环扎组(宫颈管长度<15 mm且宫口未开,10例)。比较不同环扎孕周单胎择期宫颈环扎组、单胎紧急宫颈环扎组患者的妊娠结局(术后延长孕周、分娩孕周、新生儿存活率、早产率、足月产率),孕24~28周环扎的单胎紧急宫颈环扎组与单胎未行宫颈环扎组患者的妊娠结局;双胎紧急宫颈环扎组与双胎择期宫颈环扎组患者的妊娠结局、环扎孕周。结果孕13~18^(+6)周、19~23^(+6)周、24~28周环扎的单胎择期宫颈环扎组患者的术后延长孕周分别为20.45(16.17,22.13)、15.30(12.70,19.00)、12.10(9.45,13.35)周,早产率分别为35.14%、12.00%、47.62%,比较差异有统计学意义(P<0.05)。孕13~18^(+6)周、19~23^(+6)周、24~28周环扎的单胎择期宫颈环扎组患者的分娩孕周、足月产率、新生儿存活率比较差异无统计学意义(P>0.05)。孕13~18^(+6)周、19~23^(+6)周、24~28周环扎的单胎紧急宫颈环扎组患者的术后延长孕周分别为(16.64±9.81)、(6.78±5.88)、(9.54±4.31)周,分娩孕周分别为(32.76±8.25)、(29.01±5.67)、(35.35±3.98)周,新生儿存活率分别为80.00%、36.36%、85.71%,比较差异有统计学意义(P<0.05);孕13~18^(+6)周、19~23^(+6)周、24~28周环扎的单胎紧急宫颈环扎组患者的足月产率、早产率比较差异无统计学意义(P>0.05)。与单胎未行宫颈环扎组比较,孕24~28周环扎的单胎紧急宫颈环扎组患者的术后延长孕周长,分娩孕周晚,新生儿存活率、足月产率高,早产率�Objective To analyze the pregnancy outcomes of cervical incompetence(CIC)patients undergoing transvaginal cervical cerclage in single and twin pregnancies,and explore the impact of different timing of cerclage on pregnancy outcomes.Methods The clinical data of 186 patients with CIC were retrospectively analyzed.According to the whether or not transvaginal cervical cerclage was done and the different timing of cervical cerclage,they were divided into group of singleton pregnancy with emergency cervical cerclage(30 cases),group of singleton pregnancy with elective cervical cerclage(120 cases),group of single pregnancy without cervical cerclage(dilatation of the uterine orifice at 24-28 weeks of gestation,13 cases),group of twin pregnancy with emergency cervical cerclage(endocervical canal length<15 mm with dialation of the uterine orifice,13 cases),group of twin pregnancy with elective cervical cerclage(endocervical canal length<15 mm with unopened uterine orifice,10 cases).Comparison was made on pregnancy outcomes(postoperative prolonged gestational weeks,gestational weeks of delivery,neonatal survival rate,preterm birth rate,and full-term birth rate)of patients in group of singleton pregnancy with elective cervical cerclage and the group of singleton pregnancy with emergency cervical cerclage with different gestational weeks of cerclage,pregnancy outcomes of patients in group of singleton pregnancy with emergency cervical cerclage and the group of singleton pregnancy without emergency cervical cerclage at 24-28 weeks of gestation,as well as the pregnancy outcomes and gestational weeks of cerclage of of patients in group of twin pregnancy with emergency cervical cerclage and the group of twin pregnancy without emergency cervical cerclage.Results The postoperative prolonged gestational weeks of patients in the group of singleton pregnancy with elective cervical cerclage who were circumcised at 13-18^(+6),19-23^(+6),and 24-28 of gestation were 20.45(16.17,22.13),15.30(12.70,19.00),and 12.10(9.45,13.35)weeks,and the
