【摘要】 目的 探讨经阴道彩色多普勒超声诊断子宫内膜息肉的价值，进一步提高子宫内膜息肉的诊断准确率。 方法 2009年1月-2010年12月，对48例子宫内膜息肉患者，经阴道彩色多普勒超声发现病灶后观察其位置、大小、内部回声及病灶内部和周边的彩色血流情况，并与手术病理结果对照。 结果 经阴道彩色多普勒超声诊断子宫内膜息肉的准确率为87.5%， 2例误诊为子宫黏膜下肌瘤，3例误诊为子宫内膜增厚，1例漏诊。 结论 经阴道彩色多普勒超声对子宫内膜息肉有较高的临床诊断价值。【Abstract】 Objective To investigate the value of transvaginal color doppler ultrasonography in the diagnosis of endometrial polyps and to further improve the diagnostic accuracy. Methods From January 2009 to December 2010, fourty-eight patients with endometrial polyps participated in this study. Transvaginal color doppler ultrasonography was used to observe the location, size, and internal echo of the lesions, and the color flow within and around the lesions. Then, we compared all the ultrasonic features with pathological findings. Results The diagnostic accuracy of transvaginal color doppler ultrasonography in the diagnosis of endometrial polyps was 87.5%. Two cases were misdiagnosed as submucosal uterine fibroids, 3 as endometrial thickening, and 1 missed. Conclusion Transvaginal color doppler ultrasonography has a high clinical value in the diagnosis of endometrial polyps.
