What are the contraindications for a Trial of Labor After Cesarean (TOLAC) as outlined in the chapter?

Contraindications for a Trial of Labor After Cesarean (TOLAC) include a previous cesarean with a classical uterine incision, previous transfundal uterine surgery, previous uterine rupture, medical or obstetric complications that preclude vaginal birth, and the inability to perform an emergency cesarean birth.

A Trial of Labor After Cesarean (TOLAC) is contraindicated in several situations. These include having a previous cesarean with a uterine incision in the upper part of the uterus, known as a classical incision, or a low transverse incision that extends into the upper part of the uterus. Other contraindications are a history of transfundal uterine surgery, previous uterine rupture, any medical or obstetric condition that makes vaginal birth unsafe, and scenarios where an emergency cesarean cannot be performed. It is important to note that TOLAC is not contraindicated with an unknown uterine incision unless there is a high suspicion of a classical scar.
