Abstract To explore the efficacy factors of prophylactic cervical cerclage for treating women with cervical incompetence, and to study it’s influencing on prognostic. Methods: From March 2017 to March 2019, 65 women with cervical incompetence who had accepted prophylactic cervical cerclage were in study group, and 65 patients with cervical incompetence who had accepted therapeutic cervical cerclage were in control group during the same period. The bleeding amount during operation, postoperative hospital stay time, gestational weeks when delivery, cervical length in the 32rd gestational week, pregnancy outcomes, extension gestational weeks after operation, or neonatal situations of women was compared between the two groups. The influencing factors of curative effect of women in the two groups were also analyzed. Results: After operation, the amount of bleeding (27.3±5.7 ml) and postoperative hospital stay (6.6±2.2 d) of women in the study group were significant lower than those of women in the control group, but the gestational weeks when delivery (37.8±4.2 weeks), cervical length in the 32rd gestational week (3.1±0.2 cm), the rate of full-term delivery (88.9%), extension gestational week after operation (9.5±2.5 weeks), neonatal body weight (2879.34±235.64g), and neonatal survival rate (92.3%) of women in the study group were significant higher (all P<0.05). The therapeutic effects of women in the study group were significantly correlated with their age and preoperative invasive manipulation (P<0.05), but were not correlated with perioperative progesterone used, the history of cervical surgery, the history of premature delivery or late abortion, and the operation time (P>0.05). Older pregnant women and invasive manipulation before operation were independent risk factors of preventive cervical cerclage (P<0.05). Conclusion: Prophylactic cervical cerclage for treating women with cervical incompetence can significantly reduce the amount of bleeding during operation and postoperative hospital stay time, prolong gestational weeks, improve full-term delivery rate, and improve neonatal survival rate and quality, which’s curative effect is affected by the age of women and preoperative invasive manipulation.
