Cervical cerclage at 23 weeks of pregnancy is relatively risky and increases the risk of premature rupture of membranes and hemorrhage. Cervical cerclage is a preventive measure against late preterm labor and should be performed by a medical professional when there is a history of cervical insufficiency, 3 or more mid-pregnancy spontaneous abortions or preterm labor. Cervical cerclage performed at 23 weeks of pregnancy is mostly an emergency cervical cerclage, which increases the risk of premature rupture of membranes, hemorrhage, etc. It should be performed after full assessment by a doctor. After cervical cerclage, it is necessary to follow the doctor’s advice to have proper bed rest for 1~2 weeks, and increase food rich in dietary fiber to prevent or improve the symptoms of constipation. And ankle pump exercise can effectively prevent the formation of lower extremity venous thrombosis. And follow the doctor’s advice on time for labor and delivery, usually in 37 weeks of pregnancy or later to remove the ring ligature, and be ready for delivery at any time.
