INTRODUCTION: Second Trimester Maternal Uterine Artery Doppler Analysis and Perinatal Outcomes
Objective: to investigate the relationship between second trimester maternal uterine artery doppler analysis and perinatal outcomes
METHODS: This study was conducted on pregnant women whose uterine artery were analyzed with doppler ultrasound at second trimester. The study was designed in a retrospective manner. Patients obstetric history, uterine artery doppler results and perinatal outcomes were collected from hospital records. The independent t test was used for statistical analysis and the p value was set as 0.05 for statistical significance.
RESULTS: A total of 526 women were enrolled the study. The mean patients age and weight and BMI were 29.8±5.5and 72.6±11.1 and 28.1±4.7 respectively. The mean second trimester uterine artery PI, RI, S/D ratio were 1.15±0.4, 0.62±0.1 and 2.93±1.2 respectively. The PI and RI ratios were higher than 0.58 and 1.6 in 226 (%42.9) and 74 (%14) women. Early diastolic notch were detected in 96 (%18.2) women. In these women the RI ratio was lower than cutt off value only in seven women whereas the PI was lower in thirty-six women. The rate of fetal growth restriction, oligohidroamnios, preterm delivery and preeclampsia were %15.6, %14.5, %14.5 and %10.4 respectively in women who have diastolic notch. There was one intrauterine fetal loss due to abruptio placenta.
DISCUSSION AND CONCLUSION: Second trimester uterine artery doppler analysis should not be recommended for screening purposes because of high false rate
