Rates and prediction of successful vaginal birth after cesarean

Semin Perinatol. 2010 Aug;34(4):244-8. doi: 10.1053/j.semperi.2010.03.003.


There have been multiple observational studies that have assessed the probability that a woman who undertakes a trial of labor after a previous cesarean delivery will have a vaginal birth. These studies have demonstrated a population-level probability of a successful vaginal birth after cesarean (VBAC) that ranges between 60% and 80%. However, within a population the chances for success of a given individual may vary to a significant degree on the basis of particular demographic characteristics and obstetric history. This review summarizes the different characteristics that have been prominently associated with successful VBAC as well as the different attempts that have been made to develop accurate prediction models for successful VBAC.
