Abstract: Objective：To retrospectively analyze the pregnancy outcome and neonatal prognosis of transvaginal cervical cerclage during pregnancy based on three different indications. Methods：Records of 66 patients with transvaginal cervical cerclage were retrospectively analyzed. Results：There were no statistically significant differences between elective cerclage group and ultrasound-indicated cerclage group in gestational age, live-birth rate and neonatal birth weight（P＞0.05）. The gestational age was（29.17±6.44） weeks in the emergency cerclage cervical group was lower than（34.06±6.66） weeks in the elective cerclage group and（35.42±4.75） weeks in the ultrasound-indicated cerclage group，the difference was statistically significant（Ｐ＜０．０５）. In the emergency cerclage cervical group，the mean cervical dilation before operation，postoperative white blood cell count，highest level of C-reactive protein of the failure group were higher than the successful group. Conclusions：Pregnancy women with elective cervical cerclage and pregnancy women with ultrasound-indicated cerclage all achieve good and similar pregnancy outcome. Through effective strengthen anti-inflammatory, emergency cerclage cervical success rate can be improved. Caesarean re-pregnancy women those who have a certain probability of occurrence of cervical incompetence during pregnancy should check changes in the cervix by B-ultrasound.
