DOPPLER STUDY OF THE UTERINE AND UMBILICALARTERY TO PREDICT INTRAUTERINE GROWTH RETARDATION

Abstract

The primary objective of this study is to transvalue the role of colour doppler sonography in the evaluation of pregnancy with intrauterine growth restriction. The study included 50 antenatal women with singleton pregnancy diagnosed as having a fetus with intrauterine growth restriction based on greyscale ultrasound findings. Further, an obstetric Doppler Ultrasound was done, and diagnostic statistics were applied to determine the Umbilical artery PI, RI, and Uterine artery PI, RI and correlating with perinatal outcomes. The specificity, sensitivity, positive predictive value, negative predictive value, and diagnostic accuracy were determined for all Doppler measurements. Among women with an identifiable cause, 42% had pregnancy-induced hypertension (PIH), 40% had moderate to severe anaemia complicating pregnancy. At the same time, 20% of the study group had no detectable cause for IUGR. The persistence of early diastolic notch beyond 26 weeks showed 60% sensitivity as a predictor for the perinatal outcome. The sensitivity of RI, PI of the uterine artery in predicting perinatal outcomes was 73 % and 76.7 %, respectively. Whereas, the sensitivity of RI, PI of the Umbilical artery in predicting perinatal outcomes was 63% and 70%, respectively. Doppler imaging provides indirect evidence of fetal compromise and is known to improve outcomes of high-risk pregnancies with intrauterine growth restriction. Hence, it is of eminent value for monitoring during the pregnancy.
