目的探讨阴道彩超在药物流产术后的应用。方法对108例药物流产术后10 d仍有阴道出血者进行阴道彩超检查,仔细观察宫腔内二维图像,并重点检测宫腔内残留物及其周围子宫肌壁血流情况。结果 98例患者宫腔内显示残留物,其中93例残留物内部或周边可检测到点状、团簇状血流信号;脉冲多普勒显示呈低阻力型动脉血流频谱,阻力指数小于0.6;5例药物流产失败,宫内仍可见孕囊回声。结论阴道彩超检查对药物流产术后阴道流血的诊断、指导临床处理有重要意义。
Objective To investigate the application of vaginal ultrasound in medical abortion. Methods Vaginal color Doppler ultrasound examination was performed on 108 cases of vaginal bleeding after 10 days of medical abortion. The intrauterine two-dimensional images were carefully observed, and the intrauterine cavity residues and the surrounding uterine wall blood flow were examined. Results 98 cases of patients showed intrauterine residue, of which 93 cases of residues can be detected inside or around the dot-like, clustered blood flow signal; pulse Doppler showed low resistance arterial blood flow spectrum, resistance index is less than 0.6 ; 5 cases of medical abortion failed intrauterine gestational sac echo still visible. Conclusion Vaginal ultrasound examination of vaginal bleeding after medical abortion diagnosis, guidance of clinical treatment of great significance.
