Curative effects of emergency cervical cerclage on cervical incompetence and related factors influencing prognosis

Objective To investigate the curative effects of emergency cervical cerclage (ECC) on cervical incompetence (CIC), and to analyze the related factors influencing prognosis. Methods The clinical and pathological data from 36 CIC patients treated by ECC in Nanyang First People’s Hospital from June 2016 to June 2018 were retrospectively collected. The curative effects were analyzed. The pregnancy outcomes were compared among patients with different cervical dilatation degrees, and the related factors influencing prognosis were analyzed. Results After ECC, gestational weeks of 36 CIC patients were prolonged by (8.55±4.86)weeks, and the neonatal survival rate was 83.33%(30/36). Compared to cervical dilatation degree>6.0 cm group, cervical dilatation degree≤6.0 cm group had longer prolongation time of gestational week, less abortion cases and better neonatal weight, and the difference between the two groups was significant (P 2.5 cm group had longer prolongation time of gestational week, less abortion cases, better neonatal weight, and the difference between the two groups was significant (P 6.0 cm were independent risk factors influencing pregnancy outcomes (P<0.05). Conclusions The perinatal outcomes are relatively better in CIC patients with cervical dilatation degree ≤6.0 cm and cervical length >2.5 cm. The cervical length ≤2.5 cm and cervical dilatation degree >6.0 cm are independent risk factors of pregnancy outcomes.
