经阴道彩超诊断极少量胚胎残留

Diagnosis Extremely Small Fetal Residue with Transvaginal Color Doppler Sonography

目的:探讨经阴道彩超对流产后极少量胚胎组织残留的诊断价值。方法:对60例流产后两周左右阴道不规则流血者经腹部彩色多普勒超声(TAS-CD)检查未见明显异常者,改行经阴道彩色多普勒超声(TVS-CD)检查,并对两者检查结果进行对比。结果:经TVS-CD检查15例于宫腔内见极少量残留(直径少于0.6 cm),其中13例于残留物内部或近宫腔处局部肌层检测到类滋养动脉血流。3例二维图像未见异常者,于近宫底处肌层探及到类滋养动脉血流。TVS-CD的漏诊率比TAS-CD低30%。结论:TVS-CD可以减少极少量胚胎残留的漏诊率,对临床处理具有重要的指导价值。

Objective：To explore the value of transvaginal color Doppler sonography in the diagnosing extremely small fetal residue.Methods：Sixty patients with postabortal after two weeks vaginal irregular bleeding were examined with TAS-CD,and the result is normal,then the results of the two methods of TAS-CD and TVS-CD examination were compared.Results：Through TVS-CD examination,15 patients with extremely small intrauterine remnants（diameter less than 0.6 cm） were found,among them 13 cases have monitored trophoblastic blood flow in the intrauterine remnants or in the meromyarian close to intrauterine,and 3 cases have monitored trophoblastic blood flow at the meromyarian close to intrauterine under TVS detection,but the two-dimensional image was normal.The missed diagnosis of TVS-CD was lower as 30% than that of TAS-CD.Conclusions：The missed diagnosis rate of extremely small intrauterine fetal residue was reduced by TVS-CD,and it is important for clinical.
