Everything You Need To Know About Vaginal Birth After Cesarean Delivery

It was once thought that if a woman had one cesarean delivery, all other babies she had should be born in the same way. Today, it is known that many women can undergo a trial of labor after a cesarean delivery (called TOLAC). After a successful TOLAC, many women will be able to give birth through the vagina (called vaginal birth after cesarean delivery, or VBAC). TOLAC is not the right choice for every woman, but it is a good choice for many women. It is important to understand the risks and benefits before deciding to attempt TOLAC and VBAC.

Your Choices

A woman who has had a previous cesarean delivery has the following choices when planning how to give birth again:

  • She can have a scheduled cesarean delivery.
  • She can try to have a VBAC. If a woman wants to try VBAC and is considered a good candidate, she will undergo TOLAC.

Of women who undergo TOLAC, 60-80% succeed and are able to give birth vaginally. But if problems arise during TOLAC, the baby may need to be born by emergency cesarean delivery. For example, if the baby is not tolerating labor, or if the labor does not progress, and emergency cesarean delivery may be needed. There are more risks such as a greater risk of infection, with having an emergency cesarean delivery after TOLAC than having a planned cesarean delivery. The least number of risks occur with a successful VBAC.

Reasons to Consider TOLAC

There are many reasons why a woman may want to consider TOLAC. Compared with a planned cesarean, a VBAC after successful TOLAC is associated with the following benefits:

  • No abdominal surgery
  • Shorter recovery period
  • Lower risk of infection
  • Less blood loss
  • For women planning to have more children, VBAC may help them avoid problems linked to multiple cesarean deliveries. These problems include hysterectomy bowel or bladder injury, and certain problems with the placenta.

TOLAC Risks

Both TOLAC and repeat planned cesarean delivery have risks. Both can cause infection, injury, blood loss and other complications. With TOLAC, the risk of most concern is the possible rupture of the cesarean scar on the uterus or the uterus itself. Although a rupture of the uterus is rare, it is very serious and may harm both mother and baby. If a woman is considered at high risk of rupture of the uterus, TOLAC should not be tried.

Is TOLAC Right For You?

You should discuss delivery options with your health care provider early in pregnancy. This way you and your health care provider have the most time to consider all of the options. Many of the factors that go into the decision are known early in pregnancy. Also, if the type of incision used in the previous cesarean delivery is not known, an attempt can be made to find out this information.

Before deciding whether to try VBAC, you need to know the risks and benefits of both TOLAC and planned cesarean delivery. You also should discuss your individual chances of having a successful TOLAC and VBAC, chances for success should be as high as possible.

Be Prepared For Changes

Be prepared for changes to your delivery plan. If you have chosen TOLAC, things can happen during pregnancy and labor that alter the balance of risks and benefits. For example, you may need to have your labor induced, which can reduce the chances of a successful vaginal delivery and perhaps increase the chance of complications during labor. In the event that circumstances change, you and your health care provider may want to reconsider your decision.

If you have chosen a repeat cesarean delivery, in some situations, TOLAC may be advised. For example, if you have planned a cesarean delivery but go into labor before your scheduled surgery, it may be best to consider TOLAC if you are far along in your labor and your baby is healthy.

Conclusion

TOLAC, VBAC and repeat cesarean birth have risks and benefits. When considering your options, you need to know the risks and weigh them against the benefits. Your health care provider can help guide you in making the best decision for you and your baby.

Although it is not possible to predict whether TOLAC and VBAC will be successful, several factors have been shown to increase or decrease the likelihood of success.
