A Prospective Study on Correlation of Cerebroplacental Ratio with Perinatal Outcome in Pregnancy with Iugr

Background: To evaluate cerebroplacental ratio in pregnancy with IUGR. Methods: This is a prospective observational study conducted at Department of Obstetrics and Gynecology, SMS Medical College & attached Hospital Jaipur from April 2021 till May 2022 on 65 women admitted in the Department of Obstetrics and Gynecology, SMS Medical College, Jaipur. After applying inclusion and exclusion criteria and taking informed consent, routine investigation and ultrasonography was done and fetal doppler was studied and cerebroplacental ratio was studied Results: From all our cases we has studied Sensitivity, Specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV), Accuracy were calculated and results combined arriving to an conclusion that UA PI was 37.14% sensitivity, 86.67% specificity, 76.47% positive predictive value, 54.17% negative predictive value and accuracy of 60%. The MCA PI has 22.86% sensitivity, 100% specificity, 100% positive predictive value, and 52.63% negative predictive value and accuracy of 58.63%. The CP Ratio calculates through (MCA PI/ UA PI) has sensitivity of 37.14%, specificity 100%, positive predictive value 100%, negative predictive value 57.69% and accuracy of 66.15%. Conclusion: Abnormal CP ratio is a better predictor of adverse perinatal outcome in IUGR. Doppler ultrasound plays a significant role in the management of growth restricted fetuses by early identification and thus helps in line of management and obstetrical surveillance
