Endometrial thickness and the Doppler sonographic parameters of the uterine arteries as discriminators of endometrial status in postmenopausal women receiving anti-hypertensive treatment
ABSTRACT The aim of the present study was to establish the Doppler sonographic parameters of the uterine arteries in postmenopausal patients with or without hypertension and to determine the value of their measurement in the prediction of endometrial pathology.
Healthy postmenopausal women (n = 23) and the ones receiving anti-hypertensive medication (n = 34) examined for both endometrial thickness and Doppler velocimetry of the uterine arteries by transvaginal sonography.
There was no significant difference between endometrial thickness and uterine artery Doppler sonographic parameters in hypertensive postmenopausal women compared to normotensive controls.
The role of Doppler examination in the differential diagnosis of endometrial pathology in patients with or without hypertension seemed not to be effective.

ABSTRACT: To determine whether measurements of blood flow in endometrial and uterine vessels by transvaginal color Doppler ultrasonography was valuable in the diagnosis of a neoplastic endometrial pathology (hyperplasia and carcinoma) in women with abnormal bleeding. This is a prospective study and included 105 post-menopausal women and 33 pre-menopausal women with abnormal uterine bleeding. All subjects underwent transvaginal color Doppler ultrasonography. We investigated whether obtained results were correlated with histopathological findings. There was no significant difference in the mean+/-S.D. RI of the left and the right uterine arteries, intramyometrial arteries and endometrial arteries between patients with neoplastic and non-neoplastic endometrium on histopathological examination. Doppler's velocity waveforms of small endometrial blood vessels could be detected in 9% of the women with non-neoplastic endometrium and in 42% of the women with neoplastic endometrium (P<0.05). The mean+/-S.D. of the endometrial thickness was significantly higher in the women with neoplastic endometrium than that of the women with non-neoplastic endometrium (16.6+/-6.1 mm vs. 9.5+/-4.7 mm, P<0.05). Doppler's velocity waveforms of uterine vessels coupled with transvaginal ultrasonography are not valuable enough to replace histopathological examination in the diagnosis of a neoplastic endometrial pathology. However, it may be helpful in cases in which invasive techniques are difficult to perform and in the differentiation of a certain group of patients at little risk of endometrial carcinoma.International Journal of Gynecology & Obstetrics 04/2003; 80(3):299-306.

ABSTRACT: We noticed an increase in endometrial thickness in women with hypertension who were treated with a combination of medications, including beta-blockers. The purpose of this study was to examine whether the endometrium of hypertensive women is thicker than that of healthy women and to determine whether endometrial thickening in hypertensive women is directly related to the antihypertensive beta-blocker treatment. We compared 3 groups of postmenopausal patients as follows: (1) women with a history of essential hypertension treated with a combination of medications, including beta-blockers; (2) women with a history of hypertension treated with a combination of medications that did not include beta-blockers; and (3) healthy women without hypertension. All patients were interviewed and examined, blood tests were performed, and endometrial thickness in the anterior-posterior diameter was measured by vaginal ultrasonography. Among the exclusion criteria were diabetes or an abnormal fasting blood glucose level, obesity, hormonal medication or replacement hormonal therapy during the previous 6 months, and a history of hormonal disturbances, infertility, or polycystic ovary syndrome. Of 45 hypertensive women enrolled in the study, 22 were treated with a beta-blocker combination medication and 23 were treated with other antihypertensive medications. They were compared with 25 healthy women. There was no statistically significant difference in endometrial thickness between women treated with medications, including beta-blockers, and those who were treated with other hypotensive agents. Twenty percent of women with hypertension and none of the healthy women had endometrium >5 mm thick (P <.017; odds ratio, 8.22; 95% confidence interval, 1.22-infinity). Twenty percent of hypertensive postmenopausal women were found to have increased endometrial thickness. However, we were unable to substantiate an association between the type of treatment administered, whether beta-blockers were included, and the increase in endometrial thickness.American Journal of Obstetrics and Gynecology 09/2000; 183(3):583-7.

ABSTRACT: We performed Doppler studies of the uterine artery in 85 women with postmenopausal and perimenopausal bleeding. Sixty-six women had non-malignant changes and 19 women had malignant changes on histologic examination of the endometrium. Uterine fibroids were detected in 30 women. When malignant changes were detected in the endometrium, uterine artery resistance index was always below 0.83. The mean uterine artery resistance index was significantly lower in the group of women with pathologic changes of the endometrium (RI = 0.77 +/- 0.03) compared to the group with non pathologic changes (RI = 0.85 +/- 0.08 p < 0.01), excluding the women with uterine fibroids. The lowest mean resistance index in the uterine artery was observed in the group of women with uterine fibroids (RI = 0.60 +/- 0.09 p < 0.001). In five of six patients with endometrial carcinoma blood vessels were detected around the myometrium by using color flow imaging. Their RI was always less than 0.5. In five patients, blood vessels were detected in uterine fibroids but their RI was always more than 0.5. All six women with endometrial carcinoma but only seven of 13 women with endometrial hyperplasia, had endometrial thickness greater than 5 mm. Doppler velocimetry of the uterine artery carries a high sensitivity (100%) in detecting pathological changes of the endometrium in patients presenting with postmenopausal or perimenopausal bleeding. The presence of high resistance in this vessel, may allow a more conservative approach in this group of patients.Acta Obstetricia Et Gynecologica Scandinavica 04/1993; 72(3):162-6.
