目的探讨异位妊娠的彩色多普勒超声图像的特征,为临床诊断提供依据。方法选取2009年9月至2011年3月收治的60例超声诊断为异位妊娠的患者,分析其超声二维图像、血流改变及频谱特征。结果 60例超声诊断异位妊娠患者经手术后确诊57例(95.0%),其中输卵管壶腹部妊娠50例,输卵管间质部妊娠3例,输卵管峡部妊娠3例,宫角妊娠1例。误诊3例(5.0%)。结论彩色多普勒超声可提供高分辨率的二维图像、血流情况及频谱特点,经腹结合经阴道探查能提高异位妊娠诊断的准确性。
Objective To investigate the characteristics of color Doppler echocardiography in ectopic pregnancy and provide the basis for clinical diagnosis. Methods Sixty patients with ectopic pregnancy diagnosed by ultrasound from September 2009 to March 2011 were enrolled in this study. Their two-dimensional images, blood flow changes and spectral features were analyzed. Results Sixty cases of ectopic pregnancy diagnosed by ultrasound were confirmed 57 cases (95.0%) after operation, including 50 cases of tubal ampulla pregnancy, 3 cases of tubal interstitial pregnancy, 3 cases of fallopian tube isthmus and 1 case of cornual pregnancy. Misdiagnosis in 3 cases (5.0%). Conclusion Color Doppler ultrasound can provide high-resolution two-dimensional images of blood flow and spectral characteristics of transabdominal vaginal exploration can improve the accuracy of diagnosis of ectopic pregnancy.
