摘要
对１０２例药物流产（药流）妇女应用经阴道彩色多普勒（ｔｒａｎｓｖａｇｉｎａｌｃｏｌｏｒＤｏｐｐｌｅｒ，ＴＶＣＤ）观察正常药流过程及出血延长者的子宫血流变化特点。探讨药流后出血时间延长的原因以及适应证选择的有关问题。结果表明，出血延长与宫腔内绒毛、蜕膜组织残留有关；子宫肌壁局灶血流丰富区并测到类似滋养层频谱，对识别宫内残留具有诊断价值；宫外孕应强调被列为禁忌证；剖宫产切口瘢痕部着床，合并肌瘤早孕妇女的肌瘤部位低可能阻碍孕囊蜕膜排出，不宜选择药流；孕囊平均径线＜５ｍｍ，药流不顺利，不宜优选推荐使用。
Objectives: To observe trophoblastic and other blood flows after medical abortion, to analyse factors of prolonged bleeding, and to select indications for medicinal termination of early pregnancy. Methods: Transvaginal color Doppler (TVCD) observation in combination with βhCG determination in clinical trial involving 102 early pregnant women. Results: In cases of prolonged bleeding trophoblastic blood flow (TBF) is more significant, after aspiration of retained tissues, parallelly with disappearance of TBF, prolonged uterine bleeding is stopped. Ectopics are contraindicated, lowerlysituated myoma and scarsiteimplantation are relatively contraindicated for medicinal abortion, too early pregnancy with too small embryonicsac is not favourable, the sac is more difficult to be expelled. Prolonged bleeding can occur in cases of amenorrhea or recovery of menstruation due to retention of decidual tissues with microvilli. Conclusion: Retention of decidual tissues with microvilli plays an important role in the mechanism of prolonged uterine bleeding during medicinal termination of early pregnancy. TVCD is very helpful in monitoring this method. Indications is necessary for choice of medical abortion.
