KSTP-TV's story found that one out of every one hundred women who have a vaginal birth after cesarean rupture their uterus during delivery. The birth usually results in a fatal delivery. Most women aren't aware it can happen, but insurance companies are. Physicians tell the authors some insurance companies strongly recommend, sometimes even threaten, doctors to perform VBACs. They are less costly. The research also found that there is a great deal of under reporting done on this topic in the medical community.
