Cervical Cerclage Some women are known to have what's called an incompetent cervix also referred to as cervical insufficiency. What Is a Cervical Cerclage? There are several different types of cervical cerclage procedures: McDonald Cerclage : the cervical opening is cinched shut with traditional surgical stitching between 16 to 18 weeks and the stitch is removed around week This is by far the most common type of cervical cerclage.

Shirodkar Cerclage : with this method the stitching is done in the walls of the cervix rather than the opening. This is a more difficult procedure compared to the traditional McDonald method, but the deeper level of the sutures is believed to reduce the risk of infection. This is permanent and will be in for all future pregnancies. The doctors take a piece of fascia lata which is like as elastic stocking out of the woman's thigh and encircle the cervix with it.

Abdomen Cerclage : the cervix is stitched shut at the very top of the cervical opening in the abdominal area. Again, this is more evasive. This method is permanent and is usually only done in cases where conventional cerclage methods are not viable.

This procedure is often indicated because doing the cerclage vaginally is difficult because of the degree of funneling, cervical dilatation or effacement. This is also often a path when a prior cervical cerclage has failed. Create a personalised ads profile. Select personalised ads. Apply market research to generate audience insights.

It is part of the cervix , which is in the lower part of the uterus. The cervix is about two inches in length but can vary in length and width during a woman's lifetime.

In order to describe the cervical os, it helps to first review the anatomy of the cervix. Depending on the stage, the position of the cervix will constantly change, sometimes moving higher and sometimes moving lower. During ovulation, the cervix will be high and positioned nearer to the top of the vagina.

This change of position will allow the cervical os to open more readily to allow sperm to enter. The secretion of cervical mucus will further accommodate the sperm by altering the environment of the vagina from its natural acidic state to a more alkaline one.

To better ensure the sperm can make their way to the cervical os, the mucus will also become thinner and clearer. During the non-fertile stage of menstruation, the cervical position will be lower and the cervical os will close. Vaginal secretions will become thicker and more acidic to protect against bacteria and other infectious agents.

After conception and the implantation of the fertilized egg in the uterus, the cervical os will change in response to both the stage of pregnancy and growth of the developing fetus. As the pregnancy progresses from the second to third trimester, the fetus will begin to descend into the uterus in preparation for birth. As labor progresses, the cervix will become softer and shorter, and the cervical os will begin to dilate. To accommodate the head of the baby during childbirth, the cervix must open to a diameter of more than four inches 10 centimeters.

In becoming wider, the cervix will also become shorter and thinner, a phenomenon known as effacement. In the process of effacement, the internal and external os will come closer together.

As effacement and dilation progress, the healthcare provider or midwife will use the extent of the cervical opening to help make treatment decisions. After cervical cerclage, your health care provider will do an ultrasound to check your baby's well-being. You might experience some spotting, cramps and painful urination for a few days.

Acetaminophen Tylenol, others is recommended for pain or discomfort. If your health care provider used stitches to reposition vaginal tissue affected by incisions in your cervix, you might notice passage of the material in two to three weeks as the stitches dissolve. If you had history-indicated cervical cerclage, you'll likely be able to go home after you recover from the anesthetic.

As a precaution, your health care provider might recommend avoiding sex for a few weeks or more, depending on the reason for the cerclage. If you had cervical cerclage because your cervix had already begun to open or an ultrasound showed that your cervix is short, you might need to remain in the hospital for observation. As a precaution, your health care provider might recommend limiting physical activity and sex until delivery.

Your health care provider will continue to monitor you closely for signs or symptoms of preterm labor. A transvaginal cervical cerclage is typically removed at around week 37 of pregnancy — or at the start of preterm labor. A McDonald cerclage can usually be removed in a health care provider's office without anesthetic, while a Shirodkar cerclage might need to be removed in a hospital or surgery center. After having a transvaginal cervical cerclage removed, you'll typically be able to resume your usual activities as you wait for labor to begin naturally.

If you expect to have a C-section and plan to have children in the future, you might choose to leave a Shirodkar cerclage in place throughout your pregnancy and after the baby is born. However, it's possible that the cerclage could affect your future fertility.

Consult your health care provider about your options. If you had a transabdominal cervical cerclage, you'll need to have another abdominal incision to remove the cerclage.

As a result, a C-section is typically recommended. Your baby will be delivered through an incision made above the cerclage. During the C-section, you can choose to have the cerclage removed or leave it in place for future pregnancies. Research suggests that cervical cerclage reduces the risk of premature birth in women with proven cervical insufficiency.

However, the timing of cervical cerclage can also affect the outcome. Emergency cervical cerclage done in the presence of advanced cervical change and prolapsed membranes has a poorer outcome.
