If the fetus is infected with inflammation after cervical cerclage, the fetus can still be preserved if the anti-infection treatment is effective, but if the infection is uncontrollable, the fetus can usually not be preserved any more. Cervical cerclage surgery is an effective way to treat cervical insufficiency, but there is a certain risk of infection. If you have an infection after cervical cerclage surgery, you can use medication under the guidance of your doctor for anti-infection treatment, and at the same time carry out fertility preservation treatment, and if the infection is under control, the fetus still has a chance of being preserved again, but you should also observe whether there is an intrauterine infection. If the infection is intrauterine infection, it may infect the fetus or cause premature labor or miscarriage, then the fetus can no longer be preserved. If you have contracted an infection after the IUD procedure, you need to go to the hospital for a thorough examination and standardized treatment under the guidance of your doctor.
