RESUMO

INTRODUCTION: Polycystic ovary syndrome (PCOS) is one of the most controversial conditions in gynecological endocrinology. After the symposium in Rotterdam in 2003, the importance of ovary morphology has become evident for the diagnosis and the composition of phenotypes. Transvaginal ultrasound with Doppler velocimetry can help us analyze the variables implied in vascularization and monitor the ovaries of women with PCOS. METHOD: Prospective study with 50 women who were divided into 2 groups (PCOS group: n=30 and Normal group = 20), submitted to transvaginal ultrasound with doppler velocimetry between the third and sixth day of the monthly period to assess size and thickness of ovarian stroma and index of resistance (IR) and pulsatility (IP) of uterine arteries, ovarian arteries and stromal vessels. RESULTS: In the PCOS group, ovarian size and thickness of ovarian stroma were significantly greater. Uterine and ovarian arteries IR and IP were significantly higher. IR and IP of stromal vessels were significantly lower in the PCOS group relative to the Normal group. CONCLUSION: PCOS female patients compared to normal women have increase size and thickness of ovarian stroma. They also present reduced ovarian flow, but there is increased vascularization of the stroma.
