Transvaginal color Doppler ultrasound of patients with unexplained hypomenorrhe / 中国医学影像技术

ABSTRACT

Objective To observe the relationship between morphological and hemodynamic changes of female internal genital organs in the patients with hypomenorrhea with transvaginal color Doppler ultrasound (TVCDS). Methods Thirty female patients with hypomenorrhea of unknown origin were studied, and 30 healthy women of eumenorrhea aged 20 to 40 years were selected as control group. The size and shape of uterus, ovaries, and the thickness of endometria of uterus were observed with TVCDS in follicular phase, ovulation phase, luteal phase and luteal atrophy phase, respectively. Hemodynamic parameters of ovarian artery, uterus artery and their branches were measured. At the same time, hormones of female were examined in 30 patients in follicular phase, ovulation phase and luteal atrophy phase, respectively. Results ①No difference of the size of uterus and ovaries, the thickness of endometria and the amount of egg follicles was found between two groups (P＞0.05). ②Compared with that in the control group, type C of endometria increased in hypomenorrhea group (P＜0.05). ③RI, PI and S/D of spiral arteries in hypomenorrhea group were higher than those in control group, but no significance in these parameters of uterine arteries, arcuate arteries and radiate arteries was found. RI of uterine arteries, arcuate arteries and radiate arteries decreased successively. ④RI, PI and S/D of ovarian arteries in hypomenorrhea group was higher than those in control group in ovulation phase (P＜0.05). Conclusion Reduction in blood supply of ovary and endometria may be the causes of hypomenorrhea with unknown origin. TVCDS can be used as a conventional examination method for these patients.
