Objective: To determine the relationship between maternal age and uterine artery Doppler flow during second trimester in normal pregnancy.Material and Method: Uterine artery Doppler screening was performed as a part of second trimester screening in singleton normal pregnant women at Maternal Fetal Medicine unit, Thammasat University Hospital between January 2011 and May 2012. Pulsatility index (PI), resistance index (RI) and systolic-diastolic ratio (S/D ratio) were measured from each uterine artery. Mean PI, RI and S/D ratio of the two vessels was calculated. Regression analysis was performed to determine the relationship between maternal age and uterine artery PI, RI and S/D ratio values.Results: Doppler ultrasound examinations of both uterine arteries were performed in 247 singleton pregnancies. There was no correlation of maternal age and uterine artery PI, RI and S/D ratio.Conclusions: In normal pregnancy, second trimester uterine artery Doppler waveform analysis was not affected by maternal age. |
