In order to assess the reliability of transvaginal ultrasonography for the detection of trophoblastic tissue retained after spontaneous first-trimester abortion and clinically thought to be complete, the clinical, sonographic and pathological data of 33 women were retrospectively analyzed. The patients' mean age was 34 years (range 24-48). The mean gestational age at presentation of symptoms was 8 weeks (range 5.1-11.1). Transvaginal sonography showed that in 18 cases retained tissue was absent, and that in 15 patients, retained trophoblastic tissue was suspected. Pathological reports (following dilatation and curettage) confirmed the absence of retained tissue in 17 cases and demonstrated its presence in 16 patients (13 in whom retained tissue was suspected by sonography and three in whom retained tissue was not suspected). Sensitivity, specificity, positive predictive value and negative predictive value in our series were 81%, 94%, 93% and 83%, respectively for the detection of retained trophoblastic tissue. We conclude that transvaginal ultrasonography is a reliable method to detect the presence of retained trophoblastic tissue following spontaneous first-trimester abortion, clinically thought to be complete.
为了评估经阴道超声检查对检测孕早期自然流产后临床上认为已完全流产但仍残留的滋养层组织的可靠性，我们回顾性分析了33例患者的临床、超声和病理数据。患者的平均年龄为34岁（范围24 - 48岁）。出现症状时的平均孕周为8周（范围5.1 - 11.1周）。经阴道超声检查显示，18例未发现残留组织，15例疑似有残留滋养层组织。病理报告（刮宫术后）证实17例无残留组织，16例有残留组织（13例超声检查疑似有残留组织，3例超声检查未疑似有残留组织）。在我们的研究系列中，检测残留滋养层组织的敏感性、特异性、阳性预测值和阴性预测值分别为81%、94%、93%和83%。我们得出结论，经阴道超声检查是检测孕早期自然流产后临床上认为已完全流产但仍残留滋养层组织的可靠方法。
