Is cervical cerclage needed if the cervix is 1.38 inches?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Thanks for sharing your history. This is an important question, and I am glad you are being proactive about it.

Quick summary of your case:

1. Current pregnancy: 15 weeks.

2. History of emergency cerclage at 18 weeks (due to cervical length 1.06 inches)

3. Current cervical length: 1.38 inches (seen during NT (nuchal translucency) scan).

Do you need a cerclage again?

Most likely not at this point; here is why:

1. Cervical length greater than 1.18 inches at 15 weeks: A cervical length of 1.38 inches is normal and reassuring. Typically, cerclage is considered if the length drops below 0.98 inches before 24 weeks or if there is a strong history of second-trimester losses or preterm birth.

2. Type of cerclage needed (if any): Since your previous cerclage was done after 16 weeks, that was likely an emergency or ultrasound-indicated. In this case, your doctor might monitor you with serial cervical length scans every one to two weeks from now until 24 weeks. If shortening is seen, they may recommend ultrasound-indicated cerclage again.

What you should do now:

1. Continue monitoring.

2. Ask for transvaginal cervical length checks; they are more accurate than abdominal scans.

3. The first recheck is usually at 16 to 17 weeks, then weekly or every two weeks if needed.

4. Watch for symptoms.

5. Pressure in the pelvis, backache, or an increase in discharge should be reported.

6. But with no symptoms and good cervical length now, you are in a good place.

Discuss with your doctor about preventive cerclage:

In some cases, especially if the previous pregnancy involved painless dilation, doctors may offer prophylactic cerclage between 12 and 14 weeks. But your current measurements do not automatically justify it unless more history supports it.

At 1.38 inches and 15 weeks, cerclage is not routinely needed, but close serial monitoring is the key. You are doing the right thing by checking early. If the cervix shortens in the coming weeks, your doctor may consider cerclage at that time.

I hope this helps.

Take care.
