Cervical insufficiency
It is one of the main causes of fetal loss during miscarriage during the second trimester
What is cervical insufficiency?
During pregnancy, the volume and weight of the uterus increase significantly, the normal cervix under the uterus is rich in collagen-rich connective tissue, which can maintain the closure of the pregnant cervix to term, and the cervical mucus can form a viscous mucus plug to protect the uterine cavity from retrograde infection by bacteria in the uterus.
When the cervix is structurally or functionally defective, the internal cervical opening is relaxed, the cervix is gradually too short, and the weight of the intrauterine pregnancy exceeds the capacity of the internal cervical orifice, resulting in progressive dilation of the cervix, herniation of the amniotic sac or secondary infection of premature rupture of membranes and miscarriage, which is called cervical insufficiency.
In layman's terms, if the uterus is compared to a pocket, ordinary people do not open the pocket until they give birth, and women with cervical insufficiency will open the pocket at that time, so the embryo and fetus are prone to miscarriage and premature birth.
Cervical insufficiency usually occurs at 16 to 24 weeks of gestation, without significant abdominal pain and redness.
Diagnosis of cervical insufficiency and**
Cervical insufficiency can usually have no symptoms, and it is easy to have miscarriage or premature birth in the second and third trimesters of pregnancy. The length of the cervix in normal people is about 30 to 40 mm, while in patients with cervical insufficiency, it is usually less than 25 mm.
In addition, between 3 and 7 days of clean menstruation, the relaxation of the cervical opening can also be detected through the uterine dilator, and if the cervical dilator can be successfully passed through the size 8 or more in the non-pregnant state, combined with the history of miscarriage, it can basically be judged as cervical insufficiency.
Cervical cerclage surgery is an effective method for uterine insufficiencyIn layman's terms, it is to use thread to suture and tighten the cervix to avoid miscarriage or premature birth caused by abnormal cervical dilation, which generally needs to be carried out at 14 to 16 weeks of gestation.
What conditions may have cervical insufficiency
If the patient has a history of 2 or more miscarriages in the second and late trimesters of pregnancy, and the typical symptoms of abortion such as ** cervical dilation and amniotic sac herniation are present, it is necessary to be alert to the presence of cervical insufficiency.
In addition, women with the following conditions are also at high risk of cervical insufficiency
Previous cervical or uterine cavity surgery, such as cervical conization (conization), cervical repair, etc.;
History of cervical injury during the first birth, etc.;
Severe cervical dysplasia, atresia stenosis, abnormal position, etc.;
Suffering from cervical fibroids and pathological dilation of the cervix during non-pregnancy.
