Abstract
Introduction: Intra uterine growth restriction (IUGR) is associated with increased perinatal mortality, morbidity and impaired neurodevelopment. Doppler velocimetry can assess the fetal hypoxia thereby deciding the timing of delivery and avoiding prematurity.
Objective: To predict the perinatal outcome in IUGR fetuses by Doppler velocimetry of umbilical artery, middle cerebral artery and descending thoracic aorta and deciding the management accordingly.
Material and methods: Twenty five IUGR fetuses were subjected for Doppler velocimetry of umbilical artery (UA), middle cerebral artery (MCA) and descending thoracic aorta (DTA). S/D ratio, PI and RI were calculated to predict he fetal hypoxia.
Observations: Umbilical artery S/D ratio was increased in 52% cases, whereas PI and RI were increased in 48% and 40% cases respectively. AEDV was found in 12% and REDV in 4% cases and were associated with 75% mortality. Positive predictive value of S/D ratio of MCA for fetal distress was 75% where as it was 85% for DTA .
Conclusion: Doppler parameters can detect the changes of fetal hypoxia, so the mortality and Morbidity can be reduced by timely intervention.
Keywords/Observations: IUGR-intrauterine growth restriction. AEDV-absent end diastolic volume. REDV- reversed end diastolic volume. S/D ratio-systolic to diastolic ratio. PI-pulsatility index. RI-resistive index
