If you've delivered a baby by C-section, you may have a choice with your next pregnancy — schedule a repeat C-section or attempt vaginal birth after C-section (VBAC).

Years ago, a C-section ended any hope of future vaginal deliveries. But today, thanks largely to changes in surgical technique, VBAC is possible in many cases. In fact, an estimated 60 to 80 percent of women who try VBAC have a successful vaginal delivery.

VBAC isn't right for everyone, though. Sometimes a pregnancy complication prevents the possibility of a successful VBAC. Many local hospitals don't offer VBAC because they don't have the staff or resources to handle emergency C-sections.
