Prediction of adverse perinatal outcome by umbilical artery to middle cerebral artery resistance index ratio in pregnancies complicated by hypertensive disorder.

ABSTRACT

This study aimed to evaluate umbilical artery to middle cerebral artery resistance index ratio above 95th percentile (UARI / MCARI 95) was able to predict adverse perinatal outcome in pregnancies complicated by hypertensive disorder. Fitty-three pregnant women with hypertensive disorder were recruited to this study. All of these women gave birth within 7 days of performing the Doppler study. The ability of UARI / MCARI 95 to predict adverse perinatal outcome was as follow sensitivity 12.5%, specificity 89.2%, positive predictive value 33.3%, negative predictive value 70.2%, false positive rate 10.8%, false negative rate 87.5% and accuracy 66%. This ratio did not qualify as a reliable screening test for prediction of adverse perinatal outcome prediction in pregnancies complicated by hypertensive disorder.
