title: [The evaluation of blood flow in uterine arteries in girls with polycystic ovary syndrome by transvaginal color Doppler ultrasonography].
abstract: OBJECTIVE
  The aim of this study was to evaluate of blood flow in uterine arteries in girls with PCOS and to determine whether uterine blood flow variations are associated with endocrine findings typical of PCOS.
  
  
  METHODS
  Seventy two girls with clinical, endocrinologic and ultrasonographic features of PCOS (mean age 18.8 +/- 1.3 years) were examined. The control subject consisted of twenty girls with regular, ovulation cycles. None of these girls had received hormonal treatment for at least 6 months before the study. Pelvic ultrasound examination was made in each patient with Acuson 128 XP/10 with the 4/5/7 MHz transvaginal transducer. Examination was performed in early follicular phase. Blood flow was made in each patient in the ascending branches of uterine arteries. Index values pulsatility index (PI) and resistance index (RI) were used for the purpose of better comparison of the data. Associations between values of PI and RI and hormones (testosterone, luteinizing hormone) were examined.
  
  
  RESULTS
  No significant differences between PI and RI of the left and right uterine artery was observed. PI in PCOS girls was mean 3.19 +/- 0.52 ranged from 2.1 to 4.3, in control girls PI was mean 2.33 +/- 0.36 ranged from 1.6 to 3.1. The PI was positively correlated (r = 0.435, p < 0.01) with testosterone and PI was positively correlated (r = 0.450, p < 0.001) with LH. The RI in PCOS patients was mean 0.87 +/- 0.04 ranged from 0.74 to 0.93, in control girls 0.72-0.87, mean 0.80 +/- 0.04. The RI was positively correlated (r = 0.466, p < 0.001) with testosterone and RI was positively correlated (r = 0.492, p < 0.001) with LH.
  
  
  CONCLUSIONS
  The elevated uterine artery resistance was observed in girls with PCOS.
