Changes in spıral artery in normal pregnancies: Doppler study

The aim of the study was to determine the pulsality and resistance index of spiral arteries during frist and second trimester of pregnaney.

Yöntem

Two-hundred and twenty-five normal pıegnancies were induded in this longitııdinal study. Abdominal ultrasonography with colour doppler was performed at following gestastional age periods: 10 to 14 weeks and 20 to 25 weeks. Pulsality and resistance index of spiral arteries were obtained.

Bulgular

İn the spiral arteries pulsatility and resistance index did not change between the week 11. 12. 13. M, and between the week 20, 21, 22, 23, 24, 25 but these index did change from the period ot 10-14 weeks to 20-25 weeks. A significant decrease in mean pulsalitility index with increasing gestational age was noted ( 0,63 to 0,18; 1=0,1817; p<0,001) and also in mean resistance index significantly decrease with advancing gestational age (0,45 to 0,37; r=0,2135;p<0,001).

Sonuç

This study revealed a correlation between the pulsalitility index or resislance index of spiral arteries and gestational age.
