The precerclage and postcerclage term delivery rate (TDR), premature delivery rate (PDR) and late abortion rate (LAR) were evaluated in 260 parturients undergoing elective cerclage at 12-16 weeks' gestation. The TDR increased from 0.49 to 0.78, the PDR dropped from 0.35 to 0.18, and the LAR dropped from 0.16 to 0.04. The rate of early and late complications was acceptable, and the fetal survival rate was significantly improved. The fetal salvage rate increased from 0.73 to 0.92, establishing a fetal salvage ratio of 1.26. Based on this experience, cerclage placement in cases of incompetent cervical os may prolong the duration of pregnancy and improve the outcome.
对260例妊娠12 - 16周接受择期宫颈环扎术的产妇的环扎术前和环扎术后足月分娩率（TDR）、早产率（PDR）和晚期流产率（LAR）进行了评估。足月分娩率从0.49升至0.78，早产率从0.35降至0.18，晚期流产率从0.16降至0.04。早期和晚期并发症发生率可接受，胎儿存活率显著提高。胎儿挽救率从0.73升至0.92，胎儿挽救比为1.26。基于这一经验，宫颈机能不全病例中行宫颈环扎术可延长妊娠期并改善结局。
