“…For this pur- Some authors have recently suggested that transvaginal color Doppler imaging can be used for the diagnosis and follow-up of trophoblastic disease and could replace pelvic arteriography. Myometrial invasion can be easily visualized by Doppler study [2,13]. The Doppler studies of blood flow in the intervillous space in early pregnancy are still rare.…”

The study groups comprised 61 pregnant women whose gestational age ranged from 7 to 12 weeks from the last menstrual period. All patients apparently had a normal developing pregnancy; there were no clinical symptoms of pathology e.g. bleeding in early pregnancy. Eighty-two patients with a clinically and ultrasonographically normal pregnancy whose gestational age ranged from 7 to 12 weeks, served as a control group. When the anatomical position of investigated area have been obtained clearly, pulsed wave Doppler sample volume was placed on the structures of interest: the both uterine arteries and intervillous space. There is no statistically significant difference between the Resistance Index (RI) in the left or right uterine artery (P greater than 0.01) and among investigated groups of patients (P greater than 0.01). The intervillous blood flow RI in the case of molar pregnancy was 0.38 with SD +/- 0.03; in blighted ovum 0.43 with SD +/- 0.03, and in missed abortion 0.43 with SD +/- 0.02. It should be stressed that in nine (31%) cases of blighted ova and in five (26%) cases of missed abortion, intervillous space flow could not be detected. In the control group, intervillous blood flow was always visualized and the mean RI was 0.45 with SD - 0.04. Statistical analysis showed significantly higher RI in control group in comparison with other groups of patients (P less than 0.01), and significantly lower RI in molar pregnancy in comparison with other groups of patients (P less than 0.01). There was no difference in RI between blighted ova and missed abortions (P greater than 0.01).

“…In advanced stages (II B, II and IV), primary irradiation is administered on principle. Experimental data indicate a direct correlation between vascularization and tumor growth [1,2], Other studies report that Doppler ultra sound might be a pertinent diagnostic tool for detecting neoplastic tissues and other abnormal changes [3][4][5][6]. Its advantages over other methods such as arteriography and digital subtraction angiography are that it is nonin vasive, painless and has no associated morbidity or mor tality.…”

The main characteristic of malignant tumors is their capacity for local destructive spread as well as infiltration into the adjacent tissue. The present study was carried out to evaluate the hemodynamic alterations in patients with advanced cervix cancer. Data of 34 patients with cervix cancer are compared to 30 healthy women with normal history. The mean pulsatility index (PI) was significantly lower in cancer patients (PI = 1.75 ± 1.27) than in controls (PI = 3.18 ± 0.99). Use of noninvasive Doppler ultrasound study physiology of uterine hemodynamics in patients with cervix cancer is of great clinical relevance and paves the way for further investigations in screening programs for cervix cancer.

“…Transabdominal DCFM has been done in nonpreg nant or pregnant women and patients with gynecologic diseases [4][5][6][7] and is especially useful for assessment of tumor vascularities in trophoblastic diseases [8,9], How ever, DCFM and/or blood flow velocity waveform can not be detected by the transabdominal approach in some patients, for example, in those with uterine cervical can cer [6]. This may be because uterine cervical cancer most often occurs in older women and the uterus is relatively small.…”

Transvaginal Doppler color flow mapping was performed on 8 Japanese women (normal, 1; menopause, 2; uterine myoma, 1; endometriosis, 2; pregnant, 2). In all 8, bilateral uterine arteries and branches could be clearly identified in shades of blue and/or red. The color flows were abundant in the pregnant women. Transvaginal Doppler color flow mapping is expected to be an important diagnostic tool for assessing uterine arterial blood flows in physiologic and pathologic conditions of the pelvis.
