“…Thus, the criteria were found to be more specific and having a higher positive predictive value than being sensitive and having a higher negative predictive value. These findings are in consonance with the findings of Bano et al [11] who observed the sensitivity, specificity, PPV, and NPV of the MCA PI to be 8.9, 100, 100, and 52.3 %, respectively, with a diagnostic accuracy of 54.4 %. The common criteria in both the studies were the PI cut-off of[1.5 adapted from Gramellini et al [12].…”

Background and Objectives Intrauterine growth restriction is associated with increased perinatal mortality and morbidity, possibly extending also in adult life, as compared to fetuses and newborns presenting characteristics of normal growth. The present study had been planned to measure the pulsatility index (PI) and resistive index of the middle cerebral artery with pulsatility and resistive index of the umbilical artery in predicting fetal growth restriction. Materials and Methods A total of 60 pregnant women with a clinical history and grayscale-screened patients were taken for Doppler analysis, and a final comparison of accuracy of Doppler indices was done with perinatal outcome. Statistical Analysis The statistical analysis was done using the Statistical Package for Social Sciences version 15.0 statistical analysis software. The values were represented in number (%) and mean ± SD. Observation and Results The umbilical artery PI had maximum sensitivity at the third visit (32-37 weeks) and maximum specificity also at the third visit (32-37 weeks). The umbilical artery resistive index had maximum sensitivity at the second visit (28-32 weeks) and maximum specificity at the third visit (32-37 weeks). The MCA PI had an overall diagnostic accuracy of 52.8 %. Conclusion The PI of the umbilical artery was more sensitive than the PI of the middle cerebral artery. Umbilical artery PI has the maximum overall diagnostic accuracy of 75 %.

“…In our study the CPR had a high specificity and positive predictive value (86% and 86.9%) similar to Gramellini et al and Lakhar et al, Shahina Bano et al showed 100% specificity of this parameter. 5,10,28 Changes in the venous circulation, ductus venosus, are shown to be associated with severely compromised foetus and correlate better with foetal acidosis according to Rizzo et al requiring urgent intervention, though in our study none of the cases reached to that stage. 29 Our results were also comparable with those of K. W. Fong et al, who showed high sensitivity and negative predictive value of MCA PI (72.4%, 85.7%; 78%, 83%) and concluded that normal MCA PI is helpful to identify foetuses without major adverse perinatal outcome.…”

“…Shahina et al [8] concluded that the C/U ratio is a better predictor of SGA fetuses and adverse perinatal outcome than the MCA PI or the UA PI used alone; the UA PI can be used to identify IUGR per se, and the MCA PI alone is not a reliable indicator for predicting fetal distress.…”

Purpose Intra uterine growth retardation (IUGR) due to fetoplacental vascular insufficiency is rampant in developing countries like India. Owing to the lack of awareness, antenatal patients often present in their third trimester for their first ultrasound examination. Alterations in the waveforms and Doppler indices of fetal middle cerebral artery (MCA), umbilical artery and bilateral uterine arteries have been extensively described in various studies in the literature. However, the role of each doppler parameter in actually predicting reduced birth weight (for gestational age) in the third trimester is often debatable and frustrating. Method A prospective study was done on 100 patients of clinically suspected IUGR/high-risk pregnancies of 31-41 weeks. The cases were followed till delivery; the doppler and grey scale findings were correlated with the birth weight of the baby. Result The highest sensitivity was found to be of HC/AC ratio, (84.4 %), the highest specificity of oligohydramnios and Cerebral/Umbilical Pulsatility ratio[C/U ratio] (100 %). The sensitivity of C/U ratio was found to be 68.8 %. Fetal MCA had the lowest sensitivity (7.7 %). Conclusion HC/AC ratio is quite sensitive, and oligohydramnios is a highly specific parameter to diagnose IUGR. However, the former has lower specificity, and the latter has very poor sensitivity. The MCA PI alone is not sensitive at all, and should not be used for screening purposes in IUGR patients. Also, C/U ratio is more sensitive than oligohydramnios and more specific than HC/AC ratio and stands out as the best parameter of all to diagnose IUGR in the third trimester.
