Cervical Cerclage: Types, Procedures, Precautions and Risks

What is Gynecology ?

The study and treatment of the diseases and medical problems of women

Gynaecology or gynecology is the medical practice dealing with the health of the female reproductive system. Almost all modern gynaecologists are also obstetricians. In many areas, the specialities of gynaecology and obstetrics overlap. The term means “the science of women”.

Obstetrics and gynaecology or obstetrics and gynecology is the medical specialty that encompasses the two subspecialties of obstetrics and gynecology.

Many medical advancements can help expectant mothers facing the risk of preterm birth to carry a pregnancy to full term. Cervical cerclage stands as one of the most effective medical interventions for preventing premature births in women with cervical insufficiency (weakened cervix).

If you are wondering about cervical cerclage, you are not alone. This article explains what the procedure is, when doctors might suggest it, how you recover after the procedure, and some things to watch out for along the way.

What is Cervical Cerclage?

Cervical cerclage is a procedure doctors sometimes use during high risk pregnancy. They place a stitch or a special tape around the cervix to help keep it closed. This helps the pregnancy last longer, lowering the risk of early labour. It can feel scary to hear you might need this but knowing what it is can make things a little less overwhelming.

The following are the two main cervical cerclage types:

• Transvaginal Cerclage: The most common approach where stitches are placed through the vagina
• Transabdominal Cerclage: Involves an abdominal incision to reach the cervix, performed either through open surgery or laparoscopy

The surgical stitches provide additional support by securely closing the cervix throughout pregnancy. This reinforcement is particularly crucial for women with cervical insufficiency, a condition where the cervix begins to dilate without contractions, typically leading to second-trimester delivery.

Doctors typically perform cervical cerclage between 12 to 14 weeks of pregnancy before the cervix begins to thin out (this timing allows for optimal cervical support during pregnancy development).

Why is Cervical Cerclage Performed?

There are three well-established indications for cervical cerclage placement:

• History-indicated (Prophylactic): Recommended for women with one or more second-trimester pregnancy losses related to painless cervical dilation without labour or placental complications
• Ultrasound-indicated: Considered when the cervical length is less than 25mm before 24 weeks of gestation in women with previous spontaneous losses or preterm births
• Physical Examination-indicated: Also known as emergency cerclage, performed for patients with advanced cervical dilation before 24 weeks, provided there are no contractions or infections

Past surgical procedures, such as LEEP operations or other cervical tissue surgeries, can lead to cervical weakness, necessitating cerclage. If you have a history of miscarriages (due to uterine abnormalities or cervical damage) your doctor may recommend it for you.

Procedure Details

• Before the Procedure: The preparation for a cervical cerclage begins with a thorough medical assessment. The gynaecologist reviews the patient’s medical history (simultaneously they do a detailed cervical examination and transvaginal ultrasound) to evaluate the cervical condition.
• During the Procedure: The surgical team will position the patient on the table, similarly to a routine gynaecological examination. You will be given anaesthesia to ensure comfort throughout the procedure. Using strong sutures, the surgeon carefully stitches the cervix closed. They secure it firmly to reduce the chances of premature dilation.
• Recovery and Aftercare: After the procedure, you’ll probably need to stay for a few hours so the team can make sure you are okay. It’s normal to have some cramping and light bleeding for a couple of days afterwards. Everyone’s experience is a little different but most people find these symptoms manageable.

Key precautions after cervical cerclage include:

• Wearing sanitary pads and avoiding tampons
• Getting adequate rest, preferably lying on the left side
• Maintaining proper hydration and regular bladder emptying
• Avoiding strenuous activities for at least 2-3 days
• Avoiding sexual activity for approximately two weeks post-procedure

Cervical Cerclage Risks

The following are some potential cervical cerclage complications:

• Infection or sepsis
• Cervical damage or scarring
• Bleeding
• Premature rupture of membranes
• Preterm labour
• Cervical stenosis (permanent narrowing)
• Potential tearing if labour occurs before stitch removal

What is the Ideal Time for Removing a Cervical Cerclage?

The timing of cervical cerclage removal is a crucial aspect of pregnancy management. Doctors typically schedule removal between 36 to 37 weeks of gestation. This timing ensures the pregnancy has reached a safe stage (while avoiding complications from leaving the cerclage in place during labour).

Certain circumstances may necessitate early cerclage removal. They are:

• Active labour
• Active vaginal bleeding
• Evidence of chorioamnionitis
• Other obstetric indications requiring immediate delivery

In patients contracting premature rupture of membranes (PPROM), doctors may leave the cerclage in place until steroid treatments for foetal lung maturity are completed. For patients with transabdominal cerclage the approach differs significantly – these stitches typically remain in place for cesarean delivery and can even be retained between pregnancies to prevent future preterm births.

When to See a Doctor

Patients should contact their gynaecologist immediately if they experience:

• Fever above 100.5°F (37.8°C) or chills
• Contractions or lower abdominal pain that occur at regular intervals
• Vaginal bleeding that saturates one sanitary pad in less than 3-4 hours
• Foul-smelling vaginal discharge
• Water breaking or leaking
• Persistent nausea and vomiting

Conclusion

Cervical cerclage can make a real difference for women aspiring for pregnancy and are struggling due to a weak cervix. If you or someone you love has faced pregnancy loss or been told their cervix is weak, this procedure might offer hope. Of course, every surgery has risks, but staying connected with your doctor and following their advice can really help things go smoothly.

Success rates remain highest when patients maintain regular communication with their doctors and respond promptly to any warning signs. Most women who receive cervical cerclage experience positive results (many carrying their pregnancies close to full term).
