Color Doppler Evaluation of Cerebral & Umbilical Pulsatility Ratio and its Usefulness in the Diagnosis of Fetal Growth Restriction

Dr. Sachin Shatagar | Dr Amit Singh

Abstract: Introduction: Fetal growth restriction (FGR) refers to the failure of a foetus to attain its genetically determined growth potential and affects 5?10% of pregnancies. Doppler ultrasound techniques are extensively used today to assess placental - umbilical and foetal cerebral blood flow abnormalities. The study aimed to examine the colour Doppler evaluation of cerebral & umbilical pulsatility ratio and its utility in the diagnosis of foetal growth restriction. Methodology: This prospective observational study included 69 clinically diagnosed cases of FGR of 31 - 41 weeks gestation. Two groups were formed based onabnormal perinatal outcomes (APO). The UMB PI, the MCA PI, and the C/U ratio were calculated. Results: The mean MCA PI ratio was 1.46?0.39 in the group without APO and 1.21?0.37 in the group with APO [p=0.0145]. At the same time, the UMB PI was comparable among both groups. The mean PI ratio in the group without APO was 1.44?0.53, and in the group with APO was 1.32?0.65. Most of them had a PI ratio >1 in both groups. A negative correlation was noted in MCA PI, UMB PI and PI ratio, where only MCA PI was significant. At a cut - off of 1.09, the MCA PI ratio showed a sensitivity of 75.00% and a specificity of 79.17%. Further, at a cut - off of 0.79, the UMB PI ratio showed a sensitivity of 78.38% and a specificity of 86.96%. Conclusion: Among different markers examined in the study, UM PI had high efficacy in both the early and the latter part of the third trimester.
