Objective: To see the predictive value of cerebroplacental ratio for evaluation of perinatal outcome in patients with high risk pregnancies. Methods: We included 112 patients recovered in our hospital with the diagnosis of gestational hypertension, preeclampsia, eclampsia, anaemia, anaemia with IUGR, preeclampsia with IUGR, oligohydramnios, previous still birth of unknown origin between (28-36) weeks of gestation from 1st July, 2018 to 30th June, 2019. All patients underwent accurate colour Doppler velocimetry examination available in our hospital. Pulsatility index ratio of MCA and UA (CPR) was evaluated in each case. CPR<1 was considered abnormal. Outcome variables were birth weight less than 10th percentile, neonatal death, still birth, emergency caesarean section for fetal distress, low APGAR score, admission to NICU and the duration of treatment. Results: In 70 patients abnormal CPR was seen. Abnormal UA PI and MCA PI were seen in 66 and 46 patients respectively.91.42% of patients with abnormal CPR had adverse outcome.83.87% and 91.30% of patients with abnormal UA PI and MCA PI had adverse outcome. CPR in high risk cases had highest sensitivity (91.42%), PPV (91.42%), NPV (89.28%) and diagnostic accuracy (89.28%). MCA had the highest specificity (90.47%). Conclusion: We found CPR to be a better index in predicting perinatal outcome in high risk pregnancies than MCA PI and UA PI alone. The use of CPR in the monitoring of high risk cases may contribute to a large extent in timely management of such cases for a better result.
