Transabdominal cervical cerclage (TAC) is a surgery performed to prevent pregnancy loss in patients with the most challenging cases of incompetent cervix (cervical insufficiency).

For decades, patients have traveled to the University of Chicago Medicine from both coasts and everywhere in between for this life-changing surgical procedure. Our experts perform more than 200 abdominal cerclages per year.

Transabdominal cerclage may be an option for you even if:

  • You’ve had a cervical tear from a previous delivery
  • You’ve had a failed transvaginal cerclage.
  • You aren’t eligible for a transvaginal cerclage.

What is a transabdominal cerclage?

A transabdominal cerclage is a small, extremely strong, woven synthetic band stitched high on the cervix. This band supports the full length of the cervix and resists the pressure the growing fetus places on it. The band prevents the cervix from opening and losing the pregnancy.

As with any surgery, there are some risks to abdominal cerclage procedures. If you think you may be a candidate for TAC, discuss the potential risks and benefits with your doctor.

What are the benefits of transabdominal cerclage?

There are several advantages with a transabdominal cerclage, including:

  • A high success rate for live birth
  • A lower chance of preterm birth and NICU care compared to transvaginal cerclage
  • No bed rest or activity modification required
  • No need for TAC removal after delivery (The TAC can be used for future pregnancies.)

What is the success rate of transabdominal cerclage?

TAC surgery is effective in at least 95% to 98% of our patients. We use a range to acknowledge that many considerations can impact how success is defined. Specifically, we measure success of a TAC with those deliveries that occur at 36 weeks or later. However, it’s important to remember that every patient is unique and that their health and risk factors play a role in a TAC’s effectiveness.

Is TAC safe?

Yes, TAC is safe. TAC surgery carries less risk than a simple C-section, particularly since placement is often performed as an outpatient procedure. From our patients’ point of view, the benefits of safely carrying a full-term pregnancy and having a healthy baby far outweigh the risks of TAC surgery and a C-section.
