Uterine artery doppler velocimetry in cases of perimenopausal bleeding

ABSTRACT

This study included 80 patients with perimenopausal bleeding, classified according to endometrium pathology, compared to 20 normal age-matching control group. Duplex transvaginal doppler velocimetry of the utretry was done for each participant, beside measurement of the endometrial thickness and the uterine volume. Our results show that the uterine artery S/D ratio and resistance index [RI], were significantly lower in the perimeopnpaual bleeding group, compared to the control group. The thickest endometrium was found in the endometrial hyperplasia group. Taking a cute off value of single layer endometrial thickness diagnosis of endometrial hyperplasia, the sensityivity was 95% and the specificity was 80%. The lowest values for the S/D ratio were in the endometrial hyperplasia and mymoatus uterus group. Taking a cut off value of S/D uteri, the sensitivity was 70% and the specificity was 55%. The lowest values were recorded in the group of endometrial hyperplasia. Taking a cut off value for the RI as uteri, the sensitivity or endometrial hyperplasia was 95%, and the specificity was 70%. Our results endorse the use of dopler velocity flowmetry, in addition to conventional sonographic evaluation of the uterine myometrium and endometrial thickness in cases of perimenopausal bleeding. Diagnostic dometrial curettage can be reserved to those with values beyond the cut off limits for the endometrial thinckess, S/D and RI
