Abstract To investigate the clinical outcomes of different induction methods of pregnant women with complete placenta previa during the second trimester of pregnancy. Methods: Retrospective analysis was conducted in 200 pregnant women with complete placenta previa during the second trimester of pregnancy from January 2015 to December 2019. According to the different induced labor methods, these women were divided into group A (82 women accepted drug for induced labor), group B (71 women accepted drug combined with uterine artery embolization (UAE) for induced labor), and group C (47 women accepted caesarean section). The clinical characteristics and the outcomes of induced labor of the women were compared among the three groups. Results: In group A, 5 cases (6.1%) underwent emergency caesarean section, 30 cases (36.6%) underwent emergency UAE, and the success rate of vaginal delivery was 93.9%. The success rate of vaginal delivery of the women in group B was 100%. The placental residual rate of the women in group B (16.9%) was significant higher than that (0%) of the women in group C and that (8.5%) of the women in group A. The labor induction time (28.9±10.5h) of the women in group B was significant longer than that (5.7±1.8h) of the women in group C and that (24.3±10.2h) of the women in group A. The blood loss during induced labor (320.6±230.4ml) was of the women in group B was significant lower than that (615.4±315.6lml) of the women in group C and that (395.4±262.5ml) of the women in group A (all P＜0.05). Conclusion: The success rate of vaginal delivery of the pregnant women with complete placenta previa after UAE combined with drug induction during the second trimester of pregnancy is high, which can effectively reduce the amount of bleeding during induction and the risk of emergency surgery.
