Analysis of 43 Gestation Outcomes About Treating Cervical Incompetence at Mid-Trimester Pregnancy by Cervical Cerclage

目的：探讨宫颈环扎术治疗孕中期宫颈机能不全的疗效，分析影响手术成功率的相关因素。方法：对43例孕14～27周合并宫颈机能不全者，施行宫颈环扎术治疗，观察妊娠结局。结果：孕14～16周手术的31例中，延长妊娠至足月24例，早产4例，流产3例，胎儿成活27例；〉16孕周手术12例中，延长妊娠至足月5例，早产4例，流产3例，胎儿存活9例，两者差异无统计学意义（P〉0．05）。结论：孕14～16周是宫颈环扎术最佳手术时机，〉16孕周手术也可提高胎儿成活率，紧急宫颈环扎术是必要的，可以延长妊娠时间，提高活婴分娩率。

Objective： To probe into the curative effect of treating cervical incompetence by cervical cerclage. Methods： 43 women （being pregnant at 14 -27 weeks） with cervical incompetence underwent cervical cerclage. Results： Among 31 surgeries for pregnancy at 14 ～ 16 weeks, there were 24 term deliveries, 4 pre - term deliveries and 3 miscarriages, 27 fetus survived. Among 12 surgeries for pregnancy 〉 16 weeks, there were 5 term deliveries, 4 pre - term deliveries and 3 miscarriages, 9 fetus survived. It showed no statistical difference between the two situations（P 〉 0.05）. Conclusion： Pregnancy at 14 -16 weeks is the best time for cervical cerclage, and it can improve survival rate of fetus for over 16 weeks pregnancy also. So emergent cervical cerclage is necessary, which can prolong the pregnancy days and improve the delivery rate of live births.
