Cervical cerclage is mainly a treatment for cervical insufficiency used for the preservation of the pregnancy; generally preventive surgery is done between 14 and 18 weeks of conception, and emergency cervical cerclage depends on the condition. Cervical insufficiency is defined as pathologic laxity and dilatation of the cervix during labor in the middle of pregnancy, which does not allow the pregnancy to progress. Typical clinical manifestations are shortening and even dilatation of the cervical canal in the absence of contractions in the middle and late stages of pregnancy, accompanied by dilatation of the membranes, followed by premature rupture of the membranes and premature delivery of the immature fetus, which is an important cause of fetal loss. Pregnant women with a history of cervical insufficiency can be treated with prophylactic cervical cerclage for fetal preservation, usually by vaginal cerclage or transperitoneal laparoscopic uterine isthmus reversal, which is performed between the 14th and 18th weeks of gestation. Emergency cervical cerclage is done in conjunction with the condition and is not limited to the week of conception. Before performing a cervical cerclage, the doctor usually performs a routine gynecological examination. If you have vaginitis or gynecological inflammation, then you need to wait until the inflammation recovers. During pregnancy, attention should be paid to regular pregnancy checkups, so that if there is any cervical insufficiency, it can be treated promptly and intervention can be made as early as possible to avoid delaying the condition.
