Emergency cervical cerclage may be performed at 24 weeks of gestation if surgical indications for cervical cerclage are present. Prophylactic cervical cerclage at 12-14 weeks of pregnancy is generally recommended for pregnant women with a diagnosis of cervical insufficiency, and may be performed laparoscopically or transabdominally in women with a history of typical cervical insufficiency who have failed transvaginal cerclage. Emergency cervical cerclage may be considered in women with painless cervical dilatation at 24 weeks of gestation and cervical dilatation of <25mm. It is currently believed that the occurrence of cervical insufficiency may be related to multiple abortions, cervical conization, induced labor and cervical injury caused by emergency labor, cervical dysplasia, infection and other factors, for three or more mid-term pregnancies with a history of spontaneous abortion or preterm delivery, it is recommended to consult a professional obstetrician to improve the necessary examination and active treatment.
