Did our AI summary help?

Cervical cerclage refers to an obstetric surgical procedure that is done in females who may have cervical insufficiency. This is done to prevent the incidence of preterm birth and also to prevent second trimester pregnancy loss.

Cervical insufficiency can be because of painless cervical dilatation, where the cervix expands, which leads to recurrent abortions, typically in the second trimester (around the fourth to sixth month of pregnancy).

During a cervical cerclage, a stitch/suture is placed around the cervix, so as to avoid the aforementioned dilatation and pregnancy loss.

Who Needs Cervical Cerclage

Women with a previous history of three or more pregnancy losses in the second trimester are often advised cerclage. Even those women who have a history of preterm births because of painless cervical dilatation are recommended to undergo this surgical procedure.

Is an Ultrasound Helpful

Ultrasound-indicated cerclage is also recommended when the transvaginal sonography shows the length of the cervix less than 25 millimetres before 24 weeks. Progressive shortening can increase the risk of preterm labour or abortions.

When is Cerclage Done

To prevent complications later on in the pregnancy, prophylactic cerclage may be done around twelve to fourteen weeks of gestation. Some may even be taken for this procedure up to 24 weeks if indicated.

What Should be Checked Before the Procedure

Before cerclage, the viability of the baby in the mother’s womb must be determined. There should not be any active infection or evidence of vaginal bleeding in the pregnant female. Uterine contractions must also be ruled out.

What Type of Anaesthesia is Given

Most commonly, regional anaesthesia is given (spinal). However, depending on the patient and other contributing factors, general anaesthesia may be chosen in some cases.

How Long is the Procedure

Cervical cerclage is not a long procedure, and is usually completed within 20-30 minutes. All aseptic precautions must be strictly maintained during this.

Is The Stitch Removed

Yes, these stitches/sutures are removed around 36-37 weeks of pregnancy, so that vaginal delivery can be facilitated. If labour begins early, the stitch must be removed as soon as possible to prevent cervical tears.

When performed correctly and timely, this procedure can prove to be favourable for the survival of the newborn baby.
