Abstract

This study was conducted to analyse the Doppler indices in umbilical artery, middle cerebral artery and uterine artery using Doppler ultrasound in a group of patients with pregnancy induced hypertension, assess the value of Doppler ultrasound in predicting the perinatal outcome in patients with pregnancy induced hypertension and evaluate the role of Doppler ultrasound in the management of pregnancy induced hypertension. Methods: This was a hospital based prospective study conducted among 150 patients who presented with pregnancy induced hypertension to the Department of Radiodiagnosis, Mysore Medical College and Research Institute, Mysore, over a period of 18 months from November 2017 to April 2019 after obtaining clearance from institutional ethics committee and written informed consent from the study participants. Results: The perinatal mortality was highest in the elevated RI (31%) group when compared to elevated S/D (25%) and elevated PI(28.5%) group. Amongst the umbilical artery waveforms highest LSCS for fetal distress was done in those with an elevated RI. Umbilical RI also had a 100% sensitivity in predicting APGAR<7 at 5 min. MCA Doppler studies revealed that when there was an increase in the Umbilical artery resistance there was a decrease in the values of MCA indices showing a brain sparing effect. In all the fetuses with a brain sparing effect the CPR was <1.08. Perinatal outcome as follows was - 48 delivered babies weighing <10th percentile and those with normal CPR had 26 babies weighing <10th percentile. 29 babies delivered by LSCS. 25 babies have APGAR values <7 at 5min. Statistical correlation was drawn and found to be significant (p<.05) in all the parameters in predicting poor perinatal outcome. Conclusion: Doppler ultrasound study is very useful in predicting pregnancy induced hypertension with adverse perinatal outcome when the Doppler velocimetry is abnormal.
