【目的】探讨子宫动脉栓塞术（uterine artery embolization ，UAE）在瘢痕子宫合并胎盘前置孕妇引产中的疗效。【方法】选择瘢痕子宫合并胎盘前置孕妇70例，根据患者意愿成分两组，每组35例。对照组应用传统药物乳酸依沙吖啶注射液（利凡诺）引产，观察组在对照组的基础上采用 UAE 。比较两组孕妇产程出血量、引产成功率、术后情况等。【结果】观察组患者中引产成功率达82．86％（29／35），明显优于对照组57．14％（20／35）；观察组患者引产过程失血量为（102．3±3．8）mL ，明显少于对照组（163．5±4．2）mL ，观察组引产后月经复潮时间（2．2±0．9）d 较对照组（3．8±0．8）d 明显缩短，其差异均有统计学意义（ P ＜0．05）；观察组产程（6．3±1．5）h 与对照组（5．7±1．3）h 比较差异无统计学意义（ P ＞0．05）。两组不良反应发生率比较差异无统计学意义（ P ＞0．05）。【结论】预防性 UAE 可降低引产过程中出血量，缩短月经复潮时间，且不增加不良反应发生率，临床应用安全，值得临床推广应用。“,”Objective] To investigate the effect of uterine artery embolization (UAE) on odinopoeia in gravi‐das with uterine scar and placenta previa .[Methods]Seventy cases of gravidas with scar uterine pregnancy and pla‐centa previa were randomly divided into two groups according to the random number table ,35 cases in each group . The gravidas in control group used the conventional drug Ethacridine Lactate Injection (rivanol) for induced abor‐tion ,while the gravidas in observation group on the base of the control group were taken uterine artery emboliza‐tion .The amount of blood loss ,the success rate of induced abortion ,and the postoperation situation were com‐pared .[Results]The success rate of induced labor in the observation group was 82 .86% (29/35) ,which was sig‐nificantly better than that of the control group 57 .14% (20/35) ;in the observation group ,the amount of blood loss was (102 .3 ± 3 .8) mL ,which was significantly less than that of the control group (163 .5 ± 4 .2) mL ,after in‐duced abortion ,the duration of menstruation (2 .2 ± 0 .9) d in the observation group ,was significantly shorter than that of the control group (3 .8 ± 0 .8) d ,and the difference was statistically significant ( P 0 .05) .There was no significant difference in the incidence of ad‐verse reactions between the two groups ( P > 0 .05) .[Conclusion]Preventive UAE can reduce the amount of bleed‐ing during induced abortion ,shorten the period of menstruation ,and does not increase the incidence of adverse re‐actions with clinical application safety ,it is worthy of clinical application .
