Uterine artery resistance index (UARI) was determined in a cohort of pregnant women complicated by a hypertensive disorder. The prevalence of the value above 95 percentile (UARI95) and its prediction of adverse perinatal outcomes were evaluated. Fifty-eight women were included in the study. The prevalence of UARI95 in this group of women was 27.6 per cent. The correlations between mean UARI95 and adverse perinatal outcomes were: 31.6 per cent sensitivity, 74.4 per cent specificity, with only 60.3 per cent accuracy. The mean UARI95 does not qualify as a reliable screening test for adverse perinatal outcomes in pregnancies complicated by hypertensive disorders.
