Abstract

Background: We aimed to determine whether the prepregnancy cerclage for women with cervical incompetence with absent ecto‑cervix affects the time from surgery to conception and subsequent pregnancy outcome.

Methods: This retrospective study was carried out on patients with at least one previous history of second-trimester abortion and extremely short cervix found by gynecological examination. A total of 40 cases of McDonald's cerclage before pregnancy were performed. The time from surgery to conception and pregnancy outcome were followed up for 4 years. The main outcomes were the time from surgery to conception, and the gestational week of delivery, miscarriage rate, preterm delivery rate.

Results: Between September 2018 and December 2022, 37 women became pregnant following prepregnancy cerclage. In total, 36 babies were born to 37 mothers. The recurrence rate of second-trimester miscarriage was 8.11% (3/37) and the preterm birth rate was 29.73% (11/37). Mean time from surgery to conception was 38w (range 2w-160w).Mean gestational age at delivery was 36 weeks +4 (256 days).The live birth rate was 100%. There were no maternal complications, no intestinal and bladder injuries.

Conclusion: Cervical incompetence patients with absent ecto‑cervix may benefit from prepregnancy cerclage without affecting the interpregnancy interval.
