:Objective(s) : To compare the role of middle cerebral artery and umbilical artery Doppler pulsatility indices in predicting the fetal outcome in intrauterine growth restriction. Method(s) : The prospective study was conducted on 121 subjects. They were divided into two groups. The study group (n=71) consists of high risk group of pregnant women with growth restricted fetuses. The control group (n=50) consists of pregnant women with healthy fetuses. Both the groups were evaluated by middle cerebral artery and umbilical artery velocimetry between 28 and 41 weeks of pregnancy. Results : Mothers with abnormal velocimetry had more number of cesarean sections to prevent fetal distress than those with normal velocimetry. The subjects with high risk factors had more number of abnormal waveforms than those without high risk factors. The predictive value of Doppler P.I for detecting abnormal fetal outcome was 94% in middle cerebral artery as against 83% for umbilical artery. The sensitivity was 71% for middle cerebral artery versus 44% for umbilical artery. Conclusion : Growth restricted fetuses with normal flow velocimetry are at a lower risk than those with abnormal velocimetry in terms of poor Apgar score and neonatal intensive care admission. The average birth weight of the neonates with abnormal Doppler studies was lower as compared to that of neonates with normal velocimetry. Thus middle cerebral artery doppler indices were a better predictor for fetal outcome in IUGR when compared with umbilical artery in terms of sensitivity and predictive value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
