The randomized management of term frank breech presentation: vaginal delivery vs. cesarean section

A prospective study of the management of term frank breech presentation is currently ongoing at LAC-USC Medical Center. To date, 57 patients have been randomized to an elective cesarean section group and 70 to a vaginal delivery group. Of the 70 patients selected for vaginal delivery, 35 had one or more inadequate pelvic measurements by x-ray pelvimetry and were scheduled for indicated cesarean section. Of the remaining 35 patients in this group, 30 delivered vaginally without perinatal death. Two of the infants, however sustained brachial plexus injuries. Of the 57 patients scheduled, 55 underwent elective cesarean section. There were no maternal deaths, but 20 (36.4%) patients experienced morbidity and 5(9.1 per cent) patients experienced intraoperative complications. Based on the data accumulated to date, it seems reasonable to allow vaginal delivery in carefully selected cases of term frank breech presentation.
