彩色多普勒超声对药物流产不全后宫内残留物的诊断价值研究

摘要

Objectives:To study the diagnostic value of color doppler ultrasound in incomplete abortion in-trauterine residue.Method:180 cases with 2 weeks vaginal bleeding after medical abortion in our hospital from 2013 January to 2013 December were randomly divided into 3 groups with 60 cases in each.A group received CDFI examination;B group received CDPI examination;C received both CDFI and CDPI examination.The pathological results were compared to evaluate the value of diagnosis.Result:In A group,the diagnostic sensitivity of incom-plete medical abortion was 91.1% (54 /56),and the accuracy was 88.3% (53 /60);in B group the sensitivity was 90.9% (50 /55)and the accuracy was 90% (54 /60);in C group,the sensitivity was 100% (56 /56),and the accuracy was 98.3% (59 /60).The sensitivity,accuracy,sensitivity,accuracy of C group was obviously higher than those of group A and B,all P <0.05.Conclusion:CDFI is of high sensitivity and low accuracy in diagnosis of incomplete medical abortion intrauterine residue.The diagnostic accuracy can be improved when combined with CD-PI.The combination of the two methods has important value in diagnosis.%目的：探析彩色多普勒超声诊断药物流产不全后宫内残留物的价值。方法：入选我院2013年1月至2013年12月收治的180例药物流产后持续阴道出血2周的患者，随机分为3组各60例，A 组采用高频彩色多普勒超声波（CDFI）检查，B 组采用能量多普勒（CDPI）检查，C 组采用 CDFI ＋CDPI 检查，并与病理结果进行比较，评价定性诊断价值。结果：A 组对药物流产不全诊断的灵敏度为91.1％（51／56），准确性为88.3％（53／60），B 组灵敏度为90.9％（50／55），准确性为90.0％（54／60），C 组灵敏度为100.0％（56／56），准确性为98.3％（59／60）。3组比较灵敏度、准确性可见，C 组灵敏度、准确性明显高于 A、B 两组，P ＜0.05。结论：高频 CDFI 对药物流产不全后宫内残留物诊断灵敏度高，准确性相对低，与 CDPI 联合，可提高诊断准确性，二者联合诊断具有重要价值。
