[Clinical outcomes and influence factors of 435 singleton pregnancies with short cervix].
Objective: To investigate the clinical outcomes of different treatment options on singleton short cervix and its influence factors. Methods: Totally 435 cases of singleton pregnancies who were diagnosed with short cervix (≤25 mm) between 12 to 33+6 gestational weeks in Peking University First Hospital from January 2018 to December 2018 were enrolled, including 21 cases with cervical length <10 mm, 414 cases with cervical length between 10 to 25 mm. The onset time was <24 gestational weeks in 106 cases, while 104 cases were at 24-29+6 gestational weeks and 225 cases of ≥30 gestational weeks. ⋯ Cervical cerclage is related with better outcome for patients with cervical length <10 mm. Neither progesterone nor cervical cerclage improves pregnancy outcome for >10 mm cervical length patients comparing with rest. Infection, sludge, in vitro fertilization, history of short cervix and history of preterm birth are independent risk factors of preterm birth in short cervix pregnancies.
