Transrectal color Doppler ultrasonography detection of the haemodynamic changes within ovarian stromal blood flow in patients with polycystic ovary syndrome / 医学研究生学报

ABSTRACT

Objective: To observe the haemodynamic changes within ovarian stromal blood flow in patients with polycystic ovary syndrome(PCOS). Methods: 41 patients with PCOS and 10 ovulatory women underwent transrectal ultrasound associated with Doppler flow measurement of the artery within ovarian stroma during the early follicular phase (days 2-5 of the menstrual cycle) or any day in patients with amenorrhea . Results:The peculiar vascular pattern wich one prominent blood vessel showed passing through the ovarian stroma from ovary gate. This sign was observed in all ovaries in patients with PCOS.There was no significiant difference in Vmax、PI、RI between left and right ovary.The Vmax,PI,RI of the right ovarian stromal artery were (18.99?3.12)cm/s, 0.74?0.12, 0.50?0.03 respectively. The indices of the left ovarian stromal artery were (18.76?3.23)cm/s, 0.75?0.11, 0.49?0.04 respectively. Conclusion: Vascularization of the ovarian stroma is prominent in patients with PCOS than in the control. The decreased vascular resistance to ovarian stromal perfusion in patients with PCOS may lead to perfusion increasment. TRS can be used as a non-invasive, convenient, and sensitive method for assessing the blood flow within the ovarian stroma.
