Endocervical cerclage

Endocervical cerclage is a more abortion-inducing method. This method is best performed around 14 weeks of pregnancy. Habitual miscarriage will occur after last night, so the operation is performed one week before the abortion. Endocervical cerclage can alleviate cervical miscarriage and fetal chromosomal abnormalities. You can learn about the best treatment method for cervical cerclage and the location of cervical ligation.

1. Best time for cervical cerclage

Generally speaking, the best time to do a cervical cerclage is between 14 and 16 weeks of pregnancy. Doing it later may cause miscarriage. Some pregnant women have habitual miscarriages, which requires a cervical cerclage one week before the miscarriage is about to occur, based on the time period of previous miscarriages. In addition, before performing cervical cerclage, you must check whether the miscarriage is caused by cervical relaxation. Do not blindly choose surgical treatment.

There are many reasons for miscarriage, for example, miscarriage may occur due to chromosomal problems in the fetus. Some men with poor sperm quality can still get pregnant, but the fetus may be prone to miscarriage after pregnancy. Therefore, miscarriage is not always a woman's problem. Both husband and wife should go to a regular hospital for examination. It is recommended to find out the cause of miscarriage so that targeted treatment can be carried out. Then consider conception after the body has recovered, so as to prevent the recurrence of miscarriage, which will put a burden on the physical and mental health of pregnant women.

2. The location of the cervix

The cervix is ​​located in the lower part of the uterus, is approximately cone-shaped, 2.5 to 3 cm long, with the upper end connected to the uterine body and the lower end extending deep into the vagina. In layman's terms, as the name suggests, it means the cervix of the uterus, which connects the vagina and the uterus. The specific location is deep in the vagina, adjacent to the uterus.

The type of uterine displacement is determined by the position of the external cervical opening in the vagina. The normal position of the uterus in an adult woman is slightly anteverted and flexed. "Inclination" refers to the angle between the long axis of the uterine body and the long axis of the vagina; "flexion" refers to the angle between the long axis of the uterine body and the long axis of the cervix. Normal anteversion means that the uterine body and the vagina form an inclination angle that is open forward and approximately right angles; normal anteflexion means that the uterine body and the cervix form a flexion angle of about 170° that is open forward. The external os and lips of the cervix are in contact with the posterior wall of the vagina. Various physiological or pathological factors may lead to changes in the angle of uterine "tilting" and "flexion", resulting in different types of uterine displacement: anterior displacement (anteversion, anteflexion, anteversion-anteflexion), posterior displacement (retroversion, retroflexion, retroversion-retroflexion and horizontal position) and lateral displacement (lateral tilt, lateral flexion, lateral tilt and lateral flexion), etc.

3. The structure of the cervix

The vault at the top of the vagina divides the cervix into two parts: the part of the cervix that protrudes into the vagina is called the cervicovaginal part, and the part above the vaginal vault is called the upper cervicovaginal part. The center of the cervix is ​​a long, slightly flattened fusiform lumen, the upper end of which is connected to the uterine cavity through the internal cervical os, and the lower end of which opens into the vagina through the external cervical os. The cervical canal is between the internal and external openings. The external cervical os is round in nulliparous women and transversely cleft in women who have given birth through vaginal delivery.
