[Clinic research for induced labour in midpregnancy women with central placenta previa].

Objective: To investigate the efficiency of uterine arterial embolization in induced labour among pregnant women with placenta previa.
Methods: All pregnant women (20 cases) with placenta previa who received induced labour in Taizhou First People's Hospital between 2009 and 2014 were included in this retrospective study. All cases were given rivanol induction combined with uterine arterial embolization and mifepristone.The antepartum and postpartum history were reviewed.
Results: 16 cases out of 20 delivered vaginally with small amount of bleeding. The other 4 cases got emergency cesarean delivery because of uncontrolled vaginal bleeding. No case needed hysterectomy.The average interval between the procedure and menstruation recover was 42 days.
Conclusions: Uterine arterial embolization improves the efficiency of induced labour and shows advantages to postpartum haemorrhage and prevent infertility. Uterine arterial embolization is recommended as a effective management for pregnancies with placenta previa state.
