Comparison of Middle Cerebral Artery and Uterine Artery Doppler in Evaluation of Intra Uterine Growth Restriction Pregnancy
Abstract
Objective: To determine the diagnostic accuracy of middle cerebral artery and uterine artery Doppler in diagnosis of intra uterine growth restriction, taking delivery outcome as the gold standard.
Methodology: This cross sectional study was conducted in the department of Obstetrics and Gynecology, Holy Family, Hospital, Rawalpindi, from 1st May 2019 to 31st October 2019. A total of 192 women with clinical diagnosed intrauterine growth restriction were included in the study. Doppler velocimetry was performed on the uterine artery and the middle cerebral artery close to the transducer. The diagnosis of IUGR by Middle cerebral artery and uterine artery was made as. After delivery, the birth weight (immediately within 6 h) was measured.
Results: Middle cerebral artery doppler test has shown sensitivity of 61.3%, specificity 93%, diagnostic accuracy by 76%, PPV 91.5% and NPV 66.1% (p=0.000) for diagnosis of Intra uterine growth restriction. Uterine artery doppler test has shown sensitivity of 28.3%, specificity 90.7%, diagnostic accuracy by 56%, PPV 78.9% and NPV 50.6% (p=0.001) for diagnosis of Intra uterine growth restriction.
Conclusion: The high variability in diagnostic efficacy of different markers is not suitable for prediction of IUGR.
