经阴道彩色多普勒超声显像对药物流产不全的诊断价值

目的探讨经阴道彩色多普勒超声显像（CDFI）诊断药物流产不全的价值。方法应用经阴道彩色多普勒超声显像（CDFI）诊断药流术后组织残留36例,均经清宫证实。结果36例应用CDFI检查宫腔内残留,可清晰显示宫腔内残留胚胎组织血流,显示近宫腔内膜子宫肌壁处出现局灶性血流丰富区,并可测到低阻型动脉血流频谱,阻力指数（RI）0.45±0.08。结论CDFI于近宫腔内膜子宫肌壁处显示局灶性血流信号丰富区是诊断药物流产不全的主要声像图表现,可指导临床治疗,有重要的临床应用价值。

The value of transvaginal color doppler flow imaging in diagnosing incomplete drug abortion

Objective To investigate the value of transvaginal color doppler flow imaging（CDFI） in diagnosing incomplete drug abortion. Methods Thirty-six cases of medical abortion residual organizations were diagnosed by CDFI. All the cases were confirmed after cleaning their uterus. Results In examination of intrauterine residual organizations in 36 cases with residual organizations , CDFI dearly indicated that there was residual embryonic tissue blood flow in the uterine cavity and there was abundant focal blood flow areas in the site of uterine endometrium and uterine muscle wails near the uterine cavity. Low-frequency spectrum of arterial blood flow was also measured. Resistance index （RI）was 0.45 ± 0.08. Conclusion CDFI indicate abundant signals of focal blood flow areas in the site of uterine endometrium and uterine muscle walls near the uterine cavity are major imaging signs for diagnosing incomplete drug abortion, which can guide clinical treatment and has important clinical value.
