Résumé
Objective: The objective of this study was to study the Doppler hemodynamic changes, compare different parameters in ovarianarteries, and review grayscale ultrasound findings in follicular phase of the cycle in polycystic ovary syndrome (PCOS) patients.Design: This was a case–control study.Patients: A total of 100 cases who had a history of oligo/anovulation and confirmed by Rotterdam criteria with 100 age-matchedcontrols who had normal menstrual history were selected. Forty patients with confirmed PCO disease (PCOD) and 50 controlpatients in various phases of spontaneous menstrual cycles.Results: Polycystic ovaries showed typical vascular pattern: Increased stromal vascularity, increased peak systolic velocityand end-diastolic velocity, and a trend toward lower resistance index and PI values, with P < 0.001. Overall, the most sensitiveand specific predictor for the diagnosis of PCOS was PI.Conclusion: The observed specific ovarian vascular pattern in PCOD patients may provide additional data for conventionalendocrinological and ultrasonic diagnostic methods for PCOD.
