Quantitative analysis of ovarian artery blood flow volume during whole pulsation cycle in patients with polycystic ovary syndrome / 第二军医大学学报

ABSTRACT

Objective To quantitatively analyze the changes of ovarian artery blood flow volume during whole pulsation cycle in patients with polycystic ovary syndrome (PCOS) by pulsed Doppler. Methods The ovarian arteries of 80 PCOS patients were examined by transvaginal color Doppler flow image (TV-CDFI). After examination of the parameters of pulsed Doppler, the ovarian artery blood flow volume in whole pulsation cycle was calculated with velocity-time integral while considering the internal diameter ofthe blood vessels. The results were compared with those of 80 healthy women of childbearing age in the control group. Results The typical spectrum of ovarian artery blood flow in PCOS patients was highspeed low-resistance waveform. The changes ofblood flow volumeand resistance index (RI) value were not significantly different at different times of the menstrual cycle (P>0.05). However, the changes of blood flow volume and RI value in the control group were significanly different at different times of the menstrual cycle (P 0.05). Conclusion Quantitative determination of ovarian blood flow volume using blood flow whole pulsation period method can provide a relatively accurate and reliable quantitative assessment of the ovarian perfusion in PCOS patients.
