Objective. The objective was to evaluate the accuracy of blood flow measurements by power Doppler in endometrial vessels in women with postmenopausal bleeding (PMB). Methods. Sixty consecutive patients with PMB participated in the study. Endometrial thickness and power Doppler measurements of small vessels in the endometrium and subendometrial tissue were performed prior to dilatation and curettage. Correlation between Doppler indices, endometrial thickness (by transvaginal sonography), and histopathologic examination was performed. A Student t test was used for statistical analysis with P < 0.05 as the level of significance. Results. Fourteen positive cases were found: 11 endometrial cancers, 1 sarcoma, 1 simple hyperplasia, and 1 complex hyperplasia with atypia. Measurements of endometrial thickness using a cutoff point of 5 mm revealed a sensitivity of 78% and specificity of 45.6% (P > 0.05, NS) for detecting endometrial pathology. Power Doppler measurements (pulsatility index cutoff point = 1.0) revealed a sensitivity of 85.7% and specificity of 89% (P = 0.661) for detecting endometrial pathology. Conclusions. The noninvasive methods for endometrial evaluation are not sensitive enough to exclude endometrial pathology. When invasive methods could not be performed, the combination of transvaginal sonography and power Doppler imaging provided the best results. When both modalities are negative, the probability of cancer is less than 5%. (C) 2000 Academic Press.
