Comparison Between Various Doppler Parameters for Predicting Fetal Growth Restriction and Perinatal Outcome

Abstract

Aim:- Correlation between various doppler indices of feto-maternal vessels with respect to sensitivity, specicity, accuracy, positive and negative predictive value. 2)To evaluate the efcacy of doppler study of feto-maternal vessels (uterine, umbilical and middle cerebral arteries) in predicting perinatal outcome in FGR cases. This observational study was conducted in 50 antenatal patients diagnosed with FGRMaterials & Methods:- who fullled the inclusion and exclusion criteria. After the clinical diagnosis of FGR, doppler studies of umbilical, uterine and middle cerebral artery were done. Sensitivity, specicity, accuracy, PPV, NPV of various doppler parameters were compared. Results were compiled and statistically analyzed. In our study, MCA doppler indices proved to be better predictor of FGR. The diagnostic accuracy of MCA PI inResults:- predicting FGR was found to be highest (68%) followed by MCA RI (62%) and MCA S/D (54%). Absent/reversed umbilical EDF had 100% specicity and 100% PPV in diagnosing FGR. Increased uterine S/D ratio and persistence of diastolic notch in late pregnancy suggested high sensitivity and a high degree of PPV for predicting FGR. Association of abnormal umbilical S/D, umbilical PI, AEDF/REDF and uterine notching with the adverse perinatal outcome has been proven statistically signicant. Majority of the cases had term delivery. 58% cases underwent caesarean. 54% of the neonates had the adverse perinatal outcome. RDS was the most common neonatal complication and two cases of neonatal mortality were observed. The present study concludes MCA doppler indices proved to be better predictor of FGR. Also, abnormalConclusion:- doppler indices directly correlate with poor neonatal outcome especially in cases of abnormal MCA study, uterine notching and absent or reversed umbilical end-diastolic ow in which early intervention is advised.
