目的：探讨子宫动脉栓塞术在胎盘前置状态中期妊娠引产中的应用。方法：选择2014 年1 月～2016 年1 月我院收治的孕 14～24 周胎盘前置状态需要终止妊娠患者32 例，随机分为两组，其中15 例先行子宫动脉栓塞术，3 小时后给予利凡诺100 mg 羊膜腔内注射引产术，联合口服米非司酮150 mg（A组），17 例行常规剖宫取胎术（B 组），比较两组的出血量及住院时间。结果：A 组产后平均出血量为284.53± 33.74 mL，平均住院时间为3.8± 0.7 天；B组平均产后出血量为546.07± 40.69 mL，平均住院时间为6.4± 0.3 天，差异均有统计学意义(P<0.05)。结论：子宫动脉栓塞术可用于胎盘前置状态的中孕引产，而且具有出血少、创伤小、可保护女性生殖生理功能的优点，值得临床推广。

英文摘要:

Objective:To discuss about application of uterine arterial embolization in induced labor during midtrimester pregnancy under placenta previa state.Methods:This paper selected 32 cases of patients who needed termination of pregnancy under placenta previa state during the 14th to the 24th week of pregnancy received by our hospital from January of 2014 to January of 2016, they were randomly divided into two groups whereby 15 were treated with uterine arterial embolization first, and then induction of labor with rivanol 100 mg amnion-cavity injection was given to them after three hours, in the meantime, they took orally 150 mg mifepristone (group A). 17 were treated with conventional cesarean section (group B). Bleeding quantities and lengths of stay of the two groups were compared.Results:Average bleeding quantity of group A after delivery was about 284.53± 33.74 mL and average length of stay was about 3.8± 0.7 days; average bleeding quantity of group B after delivery was about 546.07± 40.69 mL and average length of stay was about 6.4 ± 0.3 days, and difference between the two groups had statistical significance (P<0.05).Conclusion:Uterine arterial embolization can be applied to induced labor during midtrimester pregnancy with advantages of small bleeding quantity, little trauma and being able to protect reproductive and physiological functions of female, so it's worth clinical promotion.
