<unk>  <unk>  refers to the practice of delivering a baby<unk> ly (naturally) after a previous baby has been delivered through<unk>  section (surgically).  .  A<unk>  section leaves a scar in the wall of the uterus.  This scar is weaker than the normal uterine wall, so if the woman goes in labor in a subsequent pregnancy there is a higher than normal risk of a ruptured uterus, a catastrophic complication.  Because of this risk an attempt at normal<unk>  delivery was for most of the 20th century considered unacceptably risky.  This opinion was challenged by many studies showing that many women with previous<unk>  sections did have successful<unk>  deliveries.  In the 1980s and 1990s there was a strong movement to encourage attempts at<unk>  delivery after<unk>  section.  For a while some regulatory bodies in the US monitored the percentage of those women with previous<unk> s who were offered<unk>  delivery, using this number as a measure of the quality of obstetrical care.  Studies in the 1990s confirmed that<unk>  delivery after previous<unk>  section was indeed much riskier than average.  The American College of Obstetrics and Gynecology issued guidelines which identify<unk>  as a high-risk delivery requiring the availabilty of an anesthesiologist, an obstetrician, and on operating room on standby  (Int J Gyn Obs; 1999; vol 66, p197). In the 1990s the rate at which<unk>  was tried fell from 26% to 13%.
According to the American Pregnancy Association, 90% of women who have undergone<unk>  deliveries are candidates for<unk> .  From 60-80% of women opting for<unk>  will successfully give birth<unk> ly.
