title: [Color Doppler imaging and measurements of intraovarian and intrauterine vascularization on basal ultrasound examination in spontaneous ovulatory and anovulatory cycles].
abstract: OBJECTIVE
  Any organs functioning directly depends on vascularization. It applies also to the uterus and ovary which go through changes of vascularization during a menstruation cycle. The aim of this investigation was to determine differences in intrauterine and ovarian stromal arterioral blood flow on basal ultrasound examination (day 2-4) between spontaneous ovulatory and anovulatory cycles.
  
  
  METHODS
  This prospective clinical investigation included 205 patients divided into two groups: with ovulatory and with anovulatory cycles.
  
  
  RESULTS
  Resistance to ovarian arterioral stromal blood flow was significantly lower in the patients with ovulatory cycles (pulsatile index--PI 0.97 +/- 0.4 vs 1.93 +/- 1.37; p = 0.001737; and (resistance index - RI 0.55 +/- 0.12 vs 0.68 +/- 0.14; p = 0.040033). There. were no statistically significant differences in arcuate arterioral blood flow in the pateints with ovulatory and anovulatory cycles (PI 1.21 +/- 0.34 vs 61 +/- 0,61 p = 0.136161 and RI 0.64 +/- 0.11 vs 0.74 +/- 0.07; p = 0.136649). The patients with ovulatory cycles had lower uterine radial arterioral blood flow than the patients with anovulatory cycles (PI 1.001 +/- 0.22 vs 1.61 +/- 0.23 p = 0.007501 and RI 0.55 +/- 0.08 vs 0.71 +/- 0.12; p = 0,0460113). The patients with ovulatory cycles had lower subendometrial arterioral blood flow resistance (PI 0.69 0.19 vs 1.385 +/- 0.09; p = 0.00622 and RI 0.44 +/- 0.09 vs 0.65 +/- 0.02; p = 0.027458).
  
  
  CONCLUSIONS
  Color Doppler ultrasuond imaging and measurements of intrauterine and ovarian stromal arterioral blood flow on basal ultrasound examination (day 2-4), showed lower resistance to blood flow in ovulatory than in anovulatory cycles.
