ABSTRACT:

Introduction: In obstetrics the complex and common problem in modern era is considered IUGR. The common methods used to identify the IUGR were NST and BPP but their results are not sensitive to manage the perinatal results. Cerebro placenta ratio is most accurate, specific, and sensitive and best predictor for the high risk pregnancies like IUGR. Cerebro placental ratio is calculated by umbilical artery and pulsatility index of middle cerebral artery. Method: The study was conducted in the Radiology Department of Lahore General Hospital. The sample size was 50 women who were suspected clinically for having IUGR and were referred to Radiology Department for Doppler Ultrasonography for better evaluation of the IUGR suspects. From the Doppler US the velocity waveform of the fetal middle artery and umbilical artery was collected. In each case the cerebro placental ratio and pulsatility index ratio was evaluated. Cerebro placental ratio (CPR) is defined abnormal when it is less than 1.08 and this is also considered cut of value. The co relation of the ratio is associated with perinatal outcome. Results: From the total antenatal sample 63% of the babies born have weight less than 2.5 kg. The live births were 44 and the intrauterine deaths were 6. The neonates who were admitted to NICU were 10. The neonates who were born with emergency cesarean were 12.From the IUDS cases the two babies have absent diastolic flow and four babies have reversal of blood flow from umbilical artery. After diagnosis the IUDs occurred within a week. Conclusion: Doppler sonography in the identification of IUGR by cerbro placental ratio is considered accurate, specific and sensitive which can help to reduce the mortality rate among the child and mother.
