Vaginal Birth After Cesarean (“VBAC”) Presents a Greater Risk of Uterine Rupture

By Thomas Greer | January 25, 2015

Most doctors agree that a vaginal birth after cesarean (“VBAC”) can be a reasonably safe option for pregnant mothers, depending on the existence of other known risk factors. The most serious risk for mothers undergoing a VBAC is uterine rupture. A uterine rupture occurs when the mother’s uterus splits open and the baby is extruded into the abdomen. This can lead to brain damage or even death of the infant. Here are some factors to consider with regard to VBAC deliveries:

  • Type of previous incision. Women who previously had a vertical C-section incision are not candidates for a later vaginal birth. The vertical incision damages the urine muscle such that it is not safe to attempt a later vaginal birth.
  • Size of the baby. A really big baby can increase the risk of uterine rupture.
  • Timing of prior C-section. If the prior C-section occurred in close proximity to the current pregnancy, the uterine muscle may not be fully healed and therefore would be at greater risk of rupture.

Even if a pregnant mother is a candidate for a VBAC initially, risk factors can develop during labor and delivery which will lead any reasonable doctor to order a C-section. The most basic patient safety rule for an OBGYN delivering a baby is that they must order a cesarean section when a safe vaginal delivery becomes unlikely. Risk factors particularly pertinent to a mother attempting a VBAC are as follows:

  • Arrest of labor. When the mother’s labor stops progressing (i.e. she dilating and the baby stops moving down the birth canal) a C-section is indicated.
  • Signs of oxygen deprivation. Fetal monitor strips can indicate whether a baby is being adequately oxygenated. Any signs that the baby’s brain is becoming damaged from oxygen deprivation should be taken by emergency cesarean section.
