经阴道彩色多普勒超声诊断不全流产

Diagnosis of incomplete abortion by transvaginal color Doppler ultrasonography

目的探讨经阴道彩色多普勒血流成像(CDFI)对不全流产的诊断价值。方法收集经阴道超声检查并经病理证实的不全流产患者45例,分析其二维声像图特点和彩色多普勒血流特征。结果本组不全流产二维声像图分为三型:Ⅰ型24例(53.3%),表现为宫腔内异常回声团;Ⅱ型15例(33.3%),表现为宫内膜回声不均匀;Ⅲ型6例(13.3%),宫腔内未见异常回声,宫内膜回声均匀。CDFI探及滋养层周围血流者42例,显示率93.3%,清宫后其刮出物见绒毛组织。CDFI未探测到滋养层周围血流者3例,其刮出物为蜕膜及坏死组织或为凝血块。二维声像图表现为Ⅱ型及Ⅲ型者滋养层周围血流的显示率分别为93.3%、100%。结论经阴道CDFI探及到滋养层周围血流,对不全流产有较高的诊断价值。

Objective To investigate the diagnostic value of transvaginal color Doppler uhrasonography in incomplete abortion. Methods Forty - five patients with incomplete abortion examined by transvaginal color Doppler ultrasonography and confirmed by pathology were enrolled in this study, the sonographic features and blood characteristics of color Doppler were analyzed . Results The sonograms of incomplete abortion were divided into 3 types. Type I had mass with abnormal echo in uterine cavity（24/45,53.3 % ）. Type II had inhomogeneous echoes in endometrium（ 15/45,33.3 % ）. Type III had no abnormal echo, and there was homogeneous echo in endometrium （6/45,13.3 % ）. The trophoblastic blood flow was found in 42 patients （ 42/45,93.3 % ）, while wasn＇ t found in 3 cases. The display rate of trophoblastic blood flow in type Ⅱ and Ⅲ was 93.3 % and 100% respectively. Conclusion CDFI can demonstrate the characteristics of trophoblastic blood flow, and it has high value for diagnosis of incomplete abortion.
