目的:通过经阴道黑白超声与经阴道彩色多谱勒超声诊断早期异位妊娠的对比研究,探讨经阴道彩色多谱勒超声诊断异位妊娠的价值。方法:90例临床拟诊为异位妊娠的患者,均同时进行经阴道黑白超声检查(TVS)和经阴道彩色多谱勒血流显像(TVS-CDFI),以手术结果为诊断的金标准,将TVS及TVS-CDFI诊断结果分别与手术结果比较,评价TVS-CDFI诊断异位妊娠的价值。结果:经阴道彩色超声(TVS-CDFI)诊断异位妊娠的敏感性100%,特异性85.7%,准确性97.7%,阳性预测值97.4%,阴性预测值100%;经阴道黑白超声(TVS)诊断异位妊娠的敏感性97.3%,准确性92.2%,特异性64.3%,阳性预测值93.6%,阴性预测值81.8%。结论:经阴道彩色超声检查在诊断异位妊娠时较黑白超声检查能为临床提供更准确的超声诊断。
OBJECTIVE: To evaluate the value of transvaginal color Doppler ultrasonography in the diagnosis of ectopic pregnancy by transvaginal colorimetric ultrasonography and transvaginal color Doppler ultrasonography. Methods: Totally 90 patients with suspected ectopic pregnancy were treated with transvaginal ultrasonography (TVS) and transvaginal color Doppler flow imaging (TVS-CDFI) simultaneously. The surgical results were used as the gold standard for diagnosis , TVS and TVS-CDFI diagnostic results were compared with the surgical results, evaluate the value of TVS-CDFI diagnosis of ectopic pregnancy. Results: The sensitivity, specificity and accuracy of transvaginal sonography (TVS-CDFI) in diagnosing ectopic pregnancy were 100%, 85.7%, 97.7%, 97.4%, and 100% respectively. The diagnostic sensitivity of ectopic pregnancy was 97.3%, accuracy 92.2%, specificity 64.3%, positive predictive value 93.6%, and negative predictive value 81.8%. Conclusion: Transvaginal sonography can provide a more accurate ultrasound diagnosis for the clinical diagnosis of ectopic pregnancy than black and white ultrasound.
