Abstract

Abstract: Background: Breech presentation affects 3‐4% of pregnancies at term and malpresentation is the primary indication for 10‐15% of cesarean deliveries. External cephalic version is an effective intervention that can decrease the need for cesarean delivery; however, timely identification of breech presentation is required. We hypothesized that women with a fetus in a breech presentation that is diagnosed after 38 weeks' estimated gestational age have a decreased likelihood of external cephalic version attempted and an increased likelihood of cesarean delivery. Methods: This was a retrospective cohort study. A chart review was performed for 251 women with breech presentation at term presenting to our tertiary referral university hospital for external cephalic version, cesarean for breech presentation, or vaginal breech delivery. Results: Vaginal delivery was significantly more likely (31.1% vs 12.5%; P <.01) in women with breech presentation diagnosed before 38 weeks' estimated gestational age as external cephalic version was offered, and subsequently attempted in a greater proportion of women diagnosed before 38 weeks. External cephalic version was more successful when performed by physicians with greater procedural volume during the 3.5 year period of the study (59.1% for providers performing at least 10 procedures vs 31.3% if performing fewer than 10 procedures, P <.01). Conclusions: Results support the need for interventions to increase timely diagnosis of breech presentation as well as improved patient counseling and use of experienced providers for external cephalic version.
