输卵管间质部妊娠和宫角妊娠经阴道彩色多普勒超声检查的诊断价值

目的探讨经阴道彩色多普勒超声检查输卵管间质部妊娠和宫角妊娠的诊断价值。方法回顾性分析2011年10月至2016年2月术后经组织病理学检查确诊的15例输卵管间质部妊娠和29例宫角妊娠的阴道超声彩色多普勒声像图特征。结果根据术后病理检查确诊，本组患者中输卵管间质部妊娠15例，其中诊断为宫外孕定位不明2例，误诊为宫角部妊娠1例，超声确诊率80．0％，误诊率6．7％。宫角妊娠29例，其中诊断为宫外孕定位不明1例，误诊为输卵管间质部妊娠1例，超声确诊率93．1％，误诊率3．4％。输卵管间质部妊娠及宫角妊娠根据病灶的声像图特征均分为妊娠囊型及混合包块型。结论对于包块较小的输卵管间质部妊娠和宫角妊娠，通过经阴道彩色多普勒超声检查能较准确的做出诊断。

Objective To explore the value of transvaginal color Doppler ultrasonography in the diagnosis of interstitial tubal pregnancy and cornual pregnancy. Methods The transvaginal color Doppler ultrasonographic features from 15 cases of interstitial tubal pregnancy and 29 cases of cornual pregnancy confirmed with postoperative histopathology in our hospital from October 2011 to February 2016 were selected for analysis. Results In the 15 cases confirmed as interstitial tubal pregnancy in this group according to the postoperative pathological report, 2 cases were diagnosed as ectopic pregnancy of unknown location, 1 case was misdiagnosed as cornual pregnancy. The diagnosis rate of ultrasound was 80.0% and misdiagnosis rate was 6.7%. In the 29 cases confirmed as cornual pregnancy according to the postoperative pathological report, 1 case was diagnosed as ectopic pregnancy of unknown location, 1 case was misdiagnosed as interstitial tubal pregnancy. The diagnosis rate was 93.1%, and the misdiagnosis rate was 3.4%. Both interstitial tubal pregnancy and cornual pregnancy could be divided into two categories according to the sonographic features of the lesion： gestational sac and mixed mass. Conclusion For interstitial tubal pregnancy and cornual pregnancy cases with relatively small mass, transvaginal color Doppler ultrasonography can give a relative accurate diagnosis.
