title: External cephalic version after previous cesarean section.
abstract: Approximately 100,000 cesarean sections are performed each year in the United States because of breech presentation. Numerous studies have shown that external cephalic version can eliminate the need for many of these operations. However, because of the fear of uterine rupture, these studies have generally excluded patients who have undergone previous cesarean section. To evaluate the validity of this exclusion policy, we studied patients with one or more previous cesarean sections and breach presentations near term. Version attempts were successful in 82% of 56 patients who had undergone a previous cesarean section. Sixty-five percent of the successful version patients went on to have vaginal birth after cesarean section. There were no serious maternal or fetal complications associated with the version attempts. We conclude that external cephalic version is a reasonable option in patients with prior low transverse cesarean section.
