Breech presentation is the most common abnormal fetal presentation and complicates approximately 3% to 4% of all pregnancies. External cephalic version (ECV) should be recommended to women with a breech singleton pregnancy, if there is no maternal or fetal contraindication. ECV increases the chance of cephalic presentation at the onset of labor and decreases the rate of cesarean delivery by almost 40%. The success rate of ECV is approximately 60%. Review of the risks and benefits for performing an ECV and for both the timing of ECV and the number of attempts should be should be discussed with the patient.
臀位是最常见的异常胎位，约占所有妊娠的3%至4%。对于单胎臀位妊娠的孕妇，若无母胎禁忌证，应建议行外倒转术（ECV）。ECV可增加临产后头位分娩的机会，并使剖宫产率降低近40%。ECV的成功率约为60%。应与患者讨论实施ECV的风险和益处、ECV的时机以及尝试次数。
