Résumé
Objective: To assess the diagnostic value of power Doppler ultrasonography in evaluating endometrial pathology in women with postmenopausal bleeding
Methods: A cross sectional study included sixty nine women with postmenopausal bleeding. All patients had power Doppler study of uterine and endometrial vessels as well as endometrial thickness measurements
Results: The mean endometrial thickness in patients with non-neoplastic endometrial pathology was significantly different from those with neoplastic pathology [5.9+/- 3.7mm, versus 13.2+/- 5.1mm, P< 0.001]. There was no significant difference in the mean +/- SD RI and PI of uterine artery between patients with neoplastic and non-neoplastic endometrium. There was statistically significant difference in the rate of positive visualization of endometrial blood flow between cases of neoplastic endometrium [41.4%] and non-neoplastic one [2.5%] [P< 0.001]. Meanwhile, endometrial artery RI was significantly different when compared between cases of neoplastic pathology [0.56 +/- 0.07] and non-neoplastic pathology [0. 65 +/- 0.09] [P < 0.05]
Conclusion: Power Doppler ultrasonic evaluation of endometrial blood flow may contribute to the correct diagnosis of endometrial disease in symptomatic postmenopausal patient and is considered a specific non invasive procedure that may limit the need for endometrial biopsy procedure to some particular patients
