经阴道彩色多普勒超声对药物流产不全的诊断价值

Diagnostic Value of Transvaginal Color Doppler Ultrasound in Drug Induced Incomplete Abortion

目的 :探讨经阴道彩色多普勒 (TVS CD)对药物流产不全的诊断价值。材料和方法 :对 62例药物流产后阴道流血患者进行二维超声和彩色多普勒 (CDFI)观察 ,用脉冲多普勒 (PWD)测量子宫肌壁及宫腔残留物内血流参数 ;血流收缩期峰值速度 (Vmax)、舒张末期血流速度 (Vmin)及阻力指数 (RI)。结果 :62例药物流产后阴道流血患者中 5 8例诊断为药物流产不全 ,其二维超声显示宫腔内不规则不均匀高回声及混合性回声块影 ,CDFI显示子宫肌壁及残留物内局灶性血流丰富区 ,血管呈多种迂曲形态 ,频谱包络毛糙 ,呈低阻力型 :RI 0 47± 0 0 5。结论 :TVS CD对药物流产不全具有较准确的诊断价值 ,值得临床应用。

Purpose:To study diagnostic value of transvaginal color Doppler ultrasound (TVS-CD) in drug induced incomplete abortion. Materials and Methods: Sixty-two patients with persisting bleeding after drug induced abortion were observed with two-dimensional ultrasound and color Doppler flow imaging (CDFI). Blood flow parameters in myometrial wall and the leftover were determined by pulsed wave Doppler(PWD). The indices included systolic maximum velocity(V max), diastolic minimum velocity(V min) as well as resistance index(RI) Results: Fifty-eight patients were diagnosed incomplete abortion, whose two-dimensional ultrasound showed an irregular and uneven high and mixed echo mass in uterine cavity. CDFI revealed flow rich areas in myometrial wall and leftovers with blood vessels of multiple circuitous appearance. Doppler spectrum showed the unevenly with lower resistance(RI 0.47).Conclusion: CDFI has a certain diagnostic value in drug induced incomplete abortion.
