经直肠超声检测底蜕膜血流及子宫螺旋动脉血流参数预测药物流产结局的价值

Value of decidua basalis and uterine spiral artery blood flow on the outcome of medical abortion

目的:探讨经直肠超声检测底蜕膜血流及子宫螺旋动脉血流参数预测药物流产结局的价值。方法:回顾分析流产完全和流产不全者30例,流产前、流产当日、流产后15d经直肠超声检测子宫底蜕膜血流分型、血流阻力指数和子宫螺旋动脉血流参数。结果:流产完全组底蜕膜Ⅰ型血流信号、子宫螺旋动脉及底蜕膜血流阻力指数显著高于流产不全组;Ⅲ型血流信号显著低于流产不全组(P<0.05);Ⅱ型血流信号与流产不全组比较无显著性差异(P>0.05);流产当天与流产后15d所有指标与流产不全组比较均无显著性差异(P>0.05)。结论:药物流产当日经直肠超声检测子宫螺旋动脉及底蜕膜阻力指数和底脱膜血流分型能有效预测药物流产结局。

Objective ： To explore the predicted value of detecting the decidua basalis and uterine spiral artery blood flow with transrectal ultrasound on the outcome of medical abortion. Methods ： A retrospective analysis was conducted on 30 women with complete and incomplete abortion. The type of decidua basalis blood flow, resistance index （RI） and uterine spiral artery blood flow indexes before medical abortion, on the fight day of abortion and 15 days after abortion were evaluated. Results： The type I decidua basalis blood flow signal and RI in the complete abortion group were significantly higher than those in the incomplete abortion group. While the type III blood flow signal was significantly lower in the complete abortion group （P 〈 0. 05 ） , and there was no significant difference in the type II blood flow signal between the two groups （ P 〉 0.05 ）. There were no significant differences in all indexes between the right day of abortion and 15 days after abortion. Conclusion： The detection of the deeidua basalis and uterine spiral artery blood flow with transrectal ultrasound on the right day of abortion could predict the outcome of medical abortion.
