B-ultrasound can show cervical insufficiency

Problems with cervical function can affect pregnancy, which is manifested as repeated miscarriages, with an incidence rate of about 15%. After a woman has experienced multiple miscarriages during pregnancy, she should check her cervix to see if there is any problem and go to the hospital for a detailed examination. If any problem is found, it can be dealt with in time, so there will be no need for miscarriage. B-ultrasound is a common examination method.

1. Can B-ultrasound show cervical incompetence?

The following are common inspection methods:

1. B-ultrasound: Abdominal or vaginal B-ultrasound is a very simple and effective examination method. It is normal for the cervical diameter to not exceed 19mm during pregnancy, and a diameter exceeding 23mm can be diagnosed. The placenta enters the cervix in the shape of a Burkholderia funnel, which is also an ultrasound image that confirms cervical insufficiency, and may result in miscarriage or premature birth.

2. Cervical examination: Non-pregnant women can do cervical palpation. If the No. 8 Hegar dilator can easily pass through the internal cervical os, it means that the muscle wall of the cervix is ​​very short and loose, which is a simple way to diagnose the disease.

3. Foley tube extension test: First, let the tube enter the uterine body, then inject 1ml of water into the tube to make the diameter of the tube reach 6mm, and then pull out the tube. If it can be pulled out easily, the cervix may be incompletely functioning and further diagnosis can be done.

4. Angiography: The diameter of the isthmus of the uterus is 2.63mm under normal circumstances. If the diameter is significantly enlarged and the uterine or cervical angle disappears, there is a problem with the cervix.

2. Causes of cervical insufficiency

1. Congenital: About one-third of patients have congenital causes of the disease.

2. Acquired ones are generally caused by certain damage to the cervix or the normal structure under the cervix after women undergo gynecological minimally invasive surgery.

3. Physiological reasons In addition to this, incomplete physiological functions can also cause the disease.

The typical history of this disease is spontaneous rupture of the placenta in late pregnancy, followed by rapid delivery of the fetus, with each pregnancy being earlier than the previous one. It is important to pay attention to the treatment of this disease, because it can easily lead to miscarriage. Therefore, it must be treated in time after the symptoms are discovered to avoid miscarriage or late infertility.
