目的探讨经阴道彩色多普勒超声在药物流产(药流)方面诊断价值,为临床治疗提供诊断及治疗依据。方法对100例药流后仍阴道持续出血患者,应用经阴道彩色多普勒超声检查,以观察残留组织的大小、部位及血流动力学变化。结果 91例患者宫内残留物中均显示血流信号,脉冲多普勒(PW)取样可检测低阻的类滋养层动脉血流频谱,特异性为100%。清出物经病理检查为绒毛膜残留及变性退变的蜕膜。结论经阴道彩超有助于判断残留并对指导临床有一定的应用价值。
Objective To investigate the diagnostic value of transvaginal color Doppler ultrasonography in medical abortion (medical abortion), and provide the basis for diagnosis and treatment for clinical treatment. Methods 100 cases of persistent vaginal bleeding after medical abortion, transvaginal color Doppler ultrasound examination to observe the size of the residual tissue, site and hemodynamic changes. Results The blood flow signals were all found in 91 patients with intrauterine residue. Pulsed Doppler (PW) sampling could detect the low resistance trophectoderm arterial blood flow spectrum with a specificity of 100%. Clearance of the pathological examination of chorionic remnant and degeneration of decidual decidualization. Conclusion Transvaginal ultrasound helps to determine the residue and to guide the clinical application of certain value.
