目的探讨子宫动脉栓塞术联合药物在终止前置胎盘中期妊娠中的可行性及疗效。方法采用Sel-dinger技术对8例前置胎盘中期妊娠需引产者进行选择性双侧子宫动脉栓塞术,同时给予米非司酮+米索前列醇或利凡诺羊膜腔内注射。结果3例患者有产前大出血,但均无产后异常出血,平均产程为8.3h,无其他并发症。结论子宫动脉栓塞术预防前置胎盘中期妊娠引产后大出血疗效确切。

Methods Sel-dinger technique was used to select bilateral uterine arterial embolization in 8 preterm placenta patients who needed induction of labor during the second trimester of pregnancy. Simultaneously, intramuscular injection of mifepristone + misoprostol or rivanol was given.
