Abstract :

 Background : Doppler indices as predictors of adverse perinatal out come in clinically suspected IUGR pregnancies and to establish the role of Doppler ultrasound in the management of IUGR pregnancy. So the aim of the study to evaluate the usefulness of middle cereal artery and umbilical artery in clinically suspected IUGR pregnancies. Materials & Methods: We studied Doppler Velocimetry of umbilical artery and Middle cereal artery in 50 cases with clinical suspicion of IUGR between 31 to 40 weeks of gestation .Pulsatility Index was used as the Doppler index. Findings of Doppler studies were correlated with the adverse perinatal outcomes like perinatal deaths, emergency CS for foetal distress, low Apgar score, (5 min Apgar<7), and admission to NICU for complications of low birth weight. Results: Cereoplacental ratio (MCA/UA PI Ratio) was most sensitive (sensitivity 95 .8%) to predict adverse outcome. It was more sensitive than either UA PI (sensitivity 91%) or MCA PI (sensitivity 87.5%). Diagnostic accuracy of Cereoplacental ratio (Accuracy=90%) was better than UAPI (Accuracy=88%) and MCAPI (Accuracy=66%) in predicting adverse outcomes.Conclusion: Fetal Doppler indices, in particular ratios that include measurements obtained from the cereal circulation, help in the recognition of the compromised growth –retarded fetus.
