To evaluate the delivery route and the indications for cesarean delivery after successful external cephalic version (ECV).
A retrospective matched case-control study was conducted at a hospital in Lisbon, Portugal, between 2002 and 2012. Each woman who underwent successful ECV (n = 44) was compared with the previous and next women who presented for labor management and who had the same parity and a singleton vertex pregnancy at term (n = 88). The outcome measures were route of delivery, indications for cesarean delivery, and incidence of nonreassuring fetal status.
Attempts at ECV were successful in 62 (46%) of 134 women, and 44 women whose fetuses remained in a cephalic presentation until delivery were included in the study. The rates of intrapartum cesarean delivery and operative vaginal delivery did not differ significantly between cases and controls (intrapartum cesarean delivery, 9 [20%] vs 16 [18%], P = 0.75; operative vaginal delivery, 14 [32%] vs 19 [22%], P = 0.20). The indications for cesarean delivery after successful ECV did not differ; in both groups, cesarean delivery was mainly performed for labor arrest disorders (cases, 6 [67%] vs controls, 13 [81%]; P = 0.63).
Successful ECV was not associated with increased rates of intrapartum cesarean delivery or operative vaginal delivery.
评估外倒转术（ECV）成功后的分娩方式及剖宫产指征。
2002年至2012年在葡萄牙里斯本的一家医院进行了一项回顾性配对病例对照研究。将每例接受成功ECV的女性（n = 44）与之前和之后前来分娩管理且孕周相同、单胎头位妊娠、产次相同的女性（n = 88）进行比较。观察指标为分娩方式、剖宫产指征及胎儿窘迫发生率。
134例女性中62例（46%）外倒转术尝试成功，44例胎儿直至分娩时仍为头位的女性纳入研究。病例组和对照组的产时剖宫产率和阴道助产率无显著差异（产时剖宫产率，9例[20%]对16例[18%]，P = 0.75；阴道助产率，14例[32%]对19例[22%]，P = 0.20）。ECV成功后的剖宫产指征无差异；两组剖宫产主要因产程停滞（病例组6例[67%]对对照组13例[81%]；P = 0.63）。
成功的ECV与产时剖宫产率或阴道助产率增加无关。
