Background:Hypertensive disorder of pregnancy is a major cause of maternal and perinatal morbidity and mortality in developing countries. The obstetrical use of Doppler sonography for monitoring high-risk pregnancies is today an indispensable procedure. Hence; the present study was conducted for assessing the effeteness of Doppler in Patients with Pregnancy Induced Hypertension.Materials & methods: A total of 20 pregnant patients between 28 to 36 weeks of pregnancy clinically diagnosed as PIH. Control group comprised of 20 patients with 28 to 36 weeks with no clinically detectable hypertension. Inclusion criteria Comprised of patients with rise of atleast 30 mm Hg and 15 mm of Hg in systolic and diastolic pressures respectively over the previous known blood pressure, patients whose previous blood pressures were not known, the blood pressure of atleast 140/90 mm of Hg were considered abnormal, singleton pregnancy, regular periods and normotensive pregnant patients with gestational age between 28 to 36 weeks of gestation. Blood pressure was recorded and ultrasound examination was done followed by Doppler. All the results were recorded and analysed using SPSS software.Results: A total of 20 patients were included in the study group and 20 subjects were enrolled in the control group. In the study group, normal S/D ration was seen in 12 subjects while abnormal was seen in 8 subjects. Among the subjects with abnormal S/D ratio, still birth and low birth weight were seen in 4 subjects and 3 subjects respectively. Conclusion: Doppler velocimetry is useful in distinguishing the serious patients from those where the approach can be a bit more conservative
