“…• Maternal body mass index (BMI): A cross-sectional analysis of 51,002 ECV trials in the United States showed lower success rates with high maternal BMI ( P <0.01). The success rate was 58.5% in women with BMI ≥40 kg/m 2 and 65% in women with normal BMI [36].…”

Currently, the rate of cesarean sections being performed in Korea is approximately 40%, with Korea ranking 4th among the Organization for Economic Co-operation and Development countries with respect to cesarean deliveries. Breech presentation at term is an important indication for cesarean section among other factors, including medicolegal concerns and pregnancies in women of advanced maternal age. Term breech presentation is associated with a higher fetal mortality rate than that associated with a cephalic presentation. Therefore, in Korea, most of these women deliver by cesarean section to avoid the complications of vaginal breech delivery. However, cesarean section is itself associated with considerable obstetric morbidity and sometimes, mortality. External cephalic version (ECV) is a useful method to reduce the cesarean section rate in women with breech presentation and therefore to reduce the incidence of breech presentation at delivery. Studies have shown that routine use of ECV reduces the cesarean section rate by approximately two-thirds in term pregnancies with breech presentation. ECV is accepted as a safe, efficacious, and cost-effective method and is recommended by both the American College of Obstetricians and Gynecologists and the Royal College of Obstetricians and Gynecologists in all pregnancies with term breech presentation, if not contraindicated. In Korea, although most clinicians are aware of the option of ECV, their relative lack of experience in performing the procedure and fear of complications render them hesitant to perform ECV. This review is aimed at guiding obstetricians by describing the efficacy, safety concerns, and technical aspects of this procedure.

“…Models have been developed to predict ECV success; different strategies are summarised by Leung and Lau . These models are of insufficient predictive value to alter practice and, given the benefits and safety of ECV, a low probability of success should not prevent an attempt.…”

Executive summary of recommendations External cephalic version (ECV)How effective is ECV in preventing noncephalic birth?Women should be informed that the success rate of ECV is approximately 50%. BWomen should be informed that a successful ECV reduces the chance of caesarean section. ADoes ECV affect the outcome of labour?Women should be informed that labour after ECV is associated with a slightly increased rate of caesarean section and instrumental delivery when compared with spontaneous cephalic presentation.

“…Several studies used a univariate or multivariate approach to identify the relevant predictors, and their heterogeneity was established in a systematic review published in 2015. 15 Besides the Newman-Peacock score, another three simplified scoring indices that are easy to apply in the clinical practice have been proposed. In a small 2-phase study with 53 (observational phase) and then 88 (validation phase) women, Wong et al 16 devised an index considering that a palpable head, the non-engagement of the fetus, symphysisfundal height and uterine relaxation were the most relevant predictors.…”
