Background: Disorders related to intra-uterine fetal growth usually had different perinatal morbidity and mortality. Accurate diagnosis of intrauterine fetal growth is a challenging difficult task, but recent technological advances are associated with significant improvements with positive impact on antenatal care. Aim of the work: The aim of this study was to evaluate the accuracy of the umbilical and middle cerebral artery Doppler indices [e.g. resistance index] in prediction of fetal outcome in pregnancies with intra-uterine growth restriction (IUGR). Patients and Methods: Forty-five pregnant females had been included in a prospective study. All had a confirmed diagnosis of IUGR. Doppler ultrasound used to record fetal middle cerebral artery [MCA] and umbilical and Doppler indices every one week (from 32 weeks onwards). Post-delivery birth weight, Apgar score at 0 and 5 minutes had been measured and correlated with Doppler indices. Results: One-fifth of the mothers participating in the study (20%) had pre-term birth and 6.7% missed the follow-up. Umbilical artery resistance index (RI) at a cut off value of (0.79) had a diagnostic accuracy of 93%. MCA RI best cut off value was 0.63 with diagnostic accuracy of 73.9%. Also, for C/U ratio had diagnostic accuracy of 92.9%. Finally, there was significant, proportional correlation between MCA RA and C/U ratio from one side and APGAR score at 0 and 5 minutes from the other side. However, the correlation between UARI and Apgar score was inverse and statistically significant. Conclusion: Doppler velocimetry of fetal circulation can provide important information regarding fetal well-being, with subsequent impact on fetal outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
