ABSTRACT

Background: This study is aimed to investigate the anterior cerebral artery (ACA) to umbilical artery (UA) pulsatility index (PI) ratio as a new Doppler parameter in comparison with the medial cerebral artery (MCA) to umbilical artery (UA). Material and Methods: This descriptive cross-sectional study was performed on pregnant women aged 24 to 36 weeks referring. Based on ultrasound criteria, the embryos were separated into two groups, the ones appropriate for gestational age (AGA), and the ones small for gestational age (SGA). Results: Mean gestational age and fetal weight in the two groups were not found to be statistically different. The difference between the mean RI of the MCA among the two studied groups was significant (P <0.05). Moreover, the difference between the mean PI of the MCA and ACA between the two groups was significant (P <0.05). Comparing the two ratios of CPR and CPR2, a statistically significant difference was observed between these two ratios (P <0.05) so that CPR2 was <1 with a higher frequency than CPR, indicating that CPR 2 is more sensitive than CPR. Conclusion: Early detection of FGR can lead to faster and more effective treatment.
