Uterine rupture

If your uterus carries a scar from previous surgery (for example, if you had a cesarean with your older child) there’s a small risk of uterine rupture in subsequent pregnancies, particularly if your cesarean involved a vertical incision high on your abdomen (known as a classical cesarean and rarely used now).

This type of scar is more likely to rupture than a low transverse scar (the most common type). If you have a classical cesarean scar you’ll likely be advised to deliver subsequent babies by elective cesarean. Low transverse cars do present a risk if you’ve had multiple cesareans so in that case you would also be advised to have en elective cesarean.

A uterine rupture may be anything from a weak area in the uterine wall or a partial rupture that doesn’t cause any ill effects to you or your baby, to a total rupture. This is most likely to happen in labor and symptoms are likely to be severe bleeding, severe pain and fetal distress. If you’re attempting VBAC (vaginal birth after cesarean) you’ll be closely monitored during labor and an emergency cesarean will be performed if necessary.

Any time you experience bleeding or abdominal pain it’s advisable to seek medical help immediately. With a severe rupture, your baby is likely to be delivered by cesarean section immediately.

Your OB-GYN or nurse-midwife can check your existing scar at your prenatal checks if you’re worried.
