彩色多普勒超声对绝经后出血子宫内膜病变的临床应用

Clinical application of color Doppler ultrasonography for uterus endometrial lesions in postmenopausal bleeding patients

目的:探讨彩色多普勒超声对绝经后子宫出血妇女子宫内膜疾病的诊断价值及对子宫内膜癌血流动力学的评估。方法:对58例绝经后子宫出血妇女进行彩色多普勒检查,观察其内膜厚度、内膜回声及血流动力学变化,并经宫腔镜或手术组织病理学证实。结果:彩色多普勒超声可以协助诊断子宫内膜的良恶性病变,在测量内膜厚度<5 mm时可以不做诊刮,定期进行观察,子宫内膜癌和良性内膜病变显示率及动脉阻力指数(RI)值有显著差异(P<0.05)。RI=0.45做为良恶性内膜病变之间的鉴别,当RI≤0.4时应考虑子宫内膜恶性病变。结论:彩色多普勒超声可做为绝经后出血妇女子宫内膜病变的重要检查手段,对内膜癌的诊断具有重要的临床应用价值。

Objective： To valuate color Doppler uhrasonography in diagnosis of uterus endometrial lesions in patients with postmenopausal bleeding. Methods：58 patients were examined with color Doppler uhrasonography and the endometrial thickness, echoes and blood flow feature were observed. The results were compared diagnose with hysteroscopy or pathology of biopsy. Results：Color Doppler uhrasonography could benign or malignant uterus endometrial lesions. For those who had endometrial thickness 〈5 mm, the dilatation and curettage could be avoided and should be observed regularly. The show rate and blood flow RI between carcinoma of endometrium and benign endometrial lesions were significant different （P〈 0.05）. RI=0.45 could be used as differentiation between benign and malignant uterus endometrial lesions. Those who had RI ≤0.4 should be considered with Doppler uhrasonography are important to diagnose malignant uterus endometrial lesions. Conclusion：Color uterus endometrial lesions in postmenopausal bleeding patients and has significant value in clinic.
