Giving birth to a healthy baby is every mother's expectation, however, Ms. Yan, a citizen, experienced a period of anxiety during pregnancy due to "cervical insufficiency". Fortunately, under the protection of the obstetrics department of the District Maternal and Child Health Hospital, recently, Ms. Yan gave birth smoothly and the mother and child were safe. 
Since Ms. Yan was 8 weeks pregnant, she began to have recurrent ** bleeding, which made her uneasy. After carefully passing the first trimester and successfully passing the posterior nuchal translucency scan and non-invasive screening, Ms. Yan was screened for fetal malformations at 22 weeks of pregnancy, and the ultrasound found that the cervix was dilated by 15 mm, which was trumpet-shaped, and she needed to be readmitted to the hospital for fetal protection**. Zhang Hui, vice president of the District Maternal and Child Health Hospital and director of the obstetrics department, organized a team consultation and diagnosed Ms. Yan with "cervical insufficiency" and recommended cervical cerclage surgery.
Cervical insufficiency (CIC) is also known as internal cervical insufficiency, cervical osophartium, and cervical insufficiency. According to Lu Feng, deputy chief physician of the obstetrics department of the District Maternal and Child Health Hospital, this symptom refers to the inability of the cervix to maintain pregnancy due to anatomical or functional defects in the absence of contractions, which eventually leads to miscarriage or premature birth. Its incidence is 01% to 2%, and 8% of second-trimester miscarriages and preterm births are associated with this, usually occurring at 18 to 25 weeks' gestation.
Example of surgery. In the face of the patient's cherished fetus, the obstetric team performed surgery on Ms. Yan when she was 23 weeks pregnant, after careful preoperative preparation, ruled out the contraindications of surgery, and avoided surgery-related complications as much as possible.
It is reported that cervical cerclage surgery uses non-absorbable threads or cerclage to certify the cervix, which strengthens the mechanical bearing support of the cervix to a certain extent, helps the internal cervix to bear the load brought by fetal growth in the third trimester of pregnancy, avoids cervical expansion, reduces the risk of upward infection, prolongs the gestational age, improves the survival rate of newborns, and then improves pregnancy outcomes.
After a week of careful postoperative management and fetal preservation**, Ms. Yan was successfully discharged from the hospital. After being discharged from the hospital, the outpatient physician of the District Maternal and Child Health Hospital insisted on follow-up until the 37th week of pregnancy and full-term admission to the hospital and the cerclage was removed. Three days after the stitches were removed, Ms. Yan successfully delivered a baby boy, and the mother and child were safe.
Doctor's tip
If there is a history of miscarriage or extremely preterm birth in the third trimester, especially in high-risk groups with more than 2 occurrences, or a history of cervical trauma in the past, to prevent cervical insufficiency, the "one thread" of cervical cerclage surgery may effectively solve the worries of pregnant mothers.
