高级动态血流成像诊断不全性药物流产的价值探讨

Role of advanced dynamic flow in diagnosis of incomplete abortion induced by drugs

摘要: 目的:探讨高级动态血流成像技术(ADF)在诊断不全性药物流产(药流)中的应用价值。方法:对120例药流后2周及以上仍有阴道出血者进行经阴道彩色多普勒血流显像(CDFI)及ADF检查,其中59例与清宫后的病理结果对比分析。结果:59例清宫患者中,ADF诊断不全性药流的敏感性为91.49%,特异性为83.33%,准确性为89.83%,阳性预期值为95.56%,阴性预期值为71.43%;CDFI分别为68.09%、66.67%、67.80%、88.89%及34.78%,ADF诊断准确性高于CDFI(P<0.05)。结论:ADF技术在诊断不全性药流方面具有较高的应用价值。

Abstract: Objective:To investigate the diagnostic value of advanced dynamic flow (ADF) in incomplete abortion induced by drugs.Methods:One hundred and twenty patients who were still bleeding after abortion induced by drugs for more than two weeks were examined by transvaginal color doppler flow imaging (CDFI) and ADF.And the outcome of 59 cases was compared with that by histological examinations after uterine curettage.Results:The sensitivity,specificity and accuracy by ADF were 91.49%,83.33% and 89.83%,respectively,and the positive and negative predictive values reached 95.56% and 71.43%,which were higher than the 68.09%,66.67%,67.80%,88.89% and 34.78% by CDFI.The accuracy by ADF was higher than CDFI (P<0.05).Conclusions:ADF is of great value in the diagnosis of incomplete abortion induced by drugs.
