Doppler Analysis of Uterine Perfusion and Ovarian Stromal Blood Flow in Polycystic Ovary Syndrome

Abstract

Objective: To investigate blood flow velocity in the ovarian stromal artery and uterine artery in women with polycystic ovary syndrome (PCOS) and to correlate these velocities with clinical and biochemical parameters. Methods: A prospective study was carried out in 55 patients with PCOS and 42 age-matched women who did not have PCOS. Clinical, biochemical, and hormonal characteristics, and utero-ovarian Doppler ultrasound blood flow parameters were determined, and correlations between the parameters were evaluated. Results: Ovarian stromal blood flow was higher (P<0.01) and uterine perfusion was lower (P<0.01) in women with PCOS compared with women who did not have PCOS. Ovarian stromal artery pulsatility index (PI) was inversely correlated with levels of dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor-1, and with the luteinizing hormone/follicle-stimulating hormone ratio. There was a positive correlation between uterine artery PI and DHEAS level. Conclusion: Doppler analysis of the uterine and intraovarian arteries may provide additional information about the etiopathogenesis of PCOS and partly explain the clinical implications of the condition.
