Abstract

Introduction: Increased in Doppler indices of uterine artery is associated with adverse pregnancy outcomes. The aim of the study was to determine the role of uterine artery pulsatility index (PI) at 18-20 weeks of pregnancy was in predicting adverse pregnancy outcomes.

Materials & Method: This prospective cohort study of color doppler assessment of uterine arteries was conducted in 173 patients referred to the perinatologist office of Sabzevar University of Medical Sciences during pregnancy in 18-20 weeks. The 95th percentile of the average PI of the uterus was recorded. Adverse pregnancy outcomes were investigated. The data were analyzed using Fisher and Mann-Whitney test and checking the mean and standard deviation in two groups, and p ≤ 0.05 level was considered significant.

Results: The PI>1.5 had a significant relationship with HTN (p=0.003). There was no significant relationship between fetal complications and PI >1.5. The relationship between HTN (p<0.001) and premature delivery (p=0.04) with mean PI>95th percentile for gestational age was significant. There was no significant relationship between the mean and percentile above 95 PI and other maternal and fetal complications.

Conclusions: Increased resistance in the uterine artery PI in the second trimester of pregnancy was associated with HTN and premature delivery. Using the 95th percentile for a person's gestational age is more suitable for determining high-risk pregnancies.
