Correlation of Fetal Doppler Velocimetry in the Perinatal Outcome of the Growth Restricted Fetuses

Introduction: Fetal growth is a process inuenced by various factors, including, fetoplacental blood ow, and endocrine development in both the mother and fetus. Any Change from the normal can result in Intrauterine Growth Restriction (IUGR), a condition associated with chronic fetal hypoxemia and signicant morbidity, including meconium aspiration syndrome, intrapartum asphyxia, and stillbirth in extreme cases. Timely identication and management of IUGR are crucial for reducing perinatal mortality rates. Abnormalities in Doppler indices, such as the cerebroplacental ratio, can serve as sensitive predictors of fetal compromise, allowing for early detection and intervention to improve outcomes for IUGR fetuses. Objectives: 1. To evaluate the role of umbilical artery Doppler in growth restricted fetuses. 2. To know the signicance of Doppler ow velocity in perinatal outcome of the growth restricted fetuses. 3. To decide the timing of delivery of the growth restricted fetuses. Materials and Methods: This study constituted a prospective examination of Doppler velocimetry involving the umbilical artery and middle cerebral artery in pregnancies aficted with Intrauterine Growth Restriction (IUGR), spanning the gestational period from 30 to 40 weeks. Results: A total of 62 cases were included in the study on the basis of inclusion criteria in all the cases. Acceptable wave forms were obtained from MCA and UA in all the cases and were followed up for perinatal outcome. Cerebroplacental ratio was most sensitive (sensitivity 78.5%) MCA-PI was most specic (specicity 84.37%) . AEDF & REDF in umbilical artery were strong predictors of adverse perinatal outcome. Diagnostic accuracy of Cerebroplacental ratio (accuracy 75%) was better than MCA-PI (Accuracy 66.6%) and UA-PI (Accuracy 65%) in predicting adverse outcome. Conclusion: IUGR in pregnancy both Cerebroplacental ratio, UAPI are strong predictors of adverse perinatal outcome, cerebroplacental ratio was most sensitive and MCA-PI was most specic index in predicting adverse outcome, Absent / reverse end diastolic ow is omnious nding associated with major perinatal outcome and mortality.
