Cervical cerclage is one of the most effective methods of treating cervical insufficiency and recurrent mid-term and late-term pregnancy miscarriages. There are certain risks to the body, which may lead to complications, the specific risks are as follows: Firstly, cervical cerclage may lead to inflammation of the amniotic sac, which may lead to intrauterine inflammation leading to fetal demise, and in severe cases, the uterus may need to be removed in order to avoid the infection problem. In severe cases, the uterus will need to be removed to avoid infection. Secondly, IUD can lead to premature rupture of membranes or obstructed labor, which can have a significant impact on the body. Thirdly, IUD can cause damage to the bladder and urethra as well as cervical laceration, which is a bit harmful to the body, and it is best not to use IUD for treatment if there is no preterm miscarriage problem. Improper handling during the cervical cerclage procedure can result in a medical infection that will eventually require termination of the pregnancy.
