Cerclage

• Cerclage is a surgical procedure to strengthen a weakened cervix during pregnancy.
• It is primarily performed to prevent preterm birth in cases of cervical insufficiency.
• The procedure involves placing a stitch around the cervix to keep it closed.
• While generally safe, potential risks include infection, bleeding, and premature rupture of membranes.
• The decision for cerclage is made after careful evaluation of the patient’s medical history and current pregnancy.

What is Cerclage?

Cerclage refers to a surgical procedure in which a stitch, or cerclage, is placed around the cervix to keep it closed during pregnancy. This procedure is commonly known as Cervical cerclage explained, and it aims to provide mechanical support to the cervix, preventing it from opening prematurely. The cervix is the lower part of the uterus that connects to the vagina, and its role is to remain closed and firm throughout pregnancy until labor begins. When the cervix is weak or shortens too early, it can lead to preterm birth.

The cerclage procedure is usually performed between 12 and 14 weeks of pregnancy, though it can sometimes be done later if cervical changes are observed. There are different types of cerclage, with the most common being the McDonald cerclage and the Shirodkar cerclage, both involving placing a suture around the cervix. In rare cases, a transabdominal cerclage may be performed, which involves placing a stitch through an abdominal incision, typically before pregnancy or in early pregnancy.

Why is Cerclage Performed?

Cerclage is performed primarily to prevent preterm birth in individuals diagnosed with cervical insufficiency, also known as an incompetent cervix. Cervical insufficiency occurs when the cervix painlessly dilates and effaces (thins) during the second trimester, leading to premature delivery of the baby. This condition can be caused by previous cervical trauma, such as certain surgical procedures, or congenital factors.

The procedure is often recommended for individuals with a history of recurrent second-trimester miscarriages or preterm births attributed to cervical insufficiency. It may also be considered for those found to have a short cervix on ultrasound during the current pregnancy, especially if they have a history of preterm birth. According to the Centers for Disease Control and Prevention (CDC), preterm birth affects about 1 in 10 babies born in the United States, and cervical insufficiency is a significant contributing factor in some of these cases.

Potential Risks and Complications of Cerclage

While cerclage is generally considered a safe and effective procedure, like any surgical intervention, it carries certain Cerclage surgery risks and potential complications. These risks must be carefully weighed against the benefits of preventing preterm birth, especially for individuals at high risk. The decision to proceed with cerclage involves a thorough discussion with a healthcare provider.

Potential risks and complications include:

• Infection: There is a risk of infection in the cervix or uterus, which can sometimes lead to premature rupture of membranes or preterm labor.
• Bleeding: Minor bleeding or spotting is common after the procedure, but excessive bleeding can occur.
• Premature rupture of membranes (PROM): The amniotic sac may break before labor begins, increasing the risk of infection and preterm delivery.
• Preterm labor: Despite the cerclage, some individuals may still go into labor prematurely.
• Cervical laceration: Injury to the cervix can occur during placement or removal of the stitch.
• Displacement of the stitch: In rare cases, the cerclage stitch may slip or break.

Patients are typically monitored closely after the procedure, and specific instructions are provided regarding activity restrictions and signs of potential complications to watch for.
