NORMAL UTERINE ARTERIAL BLOOD-FLOW IN POSTMENOPAUSAL WOMEN ASSESSED BY TRANSVAGINAL COLOR DOPPLER ULTRASONOGRAPHY

We used transvaginal color Doppler sonography to study uterine artery blood flow velocity waveforms in 345 normal postmenopausal women who h ad never been on hormone replacement thera Our objective was to establ ish the standard baseline flow values for normal postmenopausal women. The mean pulsatility index was 3.38 +/- 1.04 and the mean resistive i ndex was 0.93 +/- 0.09. There was a positive correlation between arter ial blood flow impedance and number of years since menopause. We belie ve that these levels may become important screening parameters for the detection of endometrial carcinoma in postmenopausal women.
