The prediction of pregnancy induced hypertension from umbilical and uterine Doppler flow study

Abstract

Background: Hypertensive disorder along with hemorrhage and infection contribute greatly to maternal mortality and morbidity. Pregnancy induced hypertension remains among the most significant and intriguing unsolved problems in obstetrics.

Methods: In this prospective analytical study investigations and color doppler findings 0f umbilical artery PI, RI and end diastolic flow in same, uterine PI, RI and persistent diastolic notch in uterine artery recorded. Total 100 Cases of PIH between 20-36 weeks of gestation in 2 years with B.P ≥ 140/90 mm hg and protienuria ≥ 1+ were observed.

Results: In this study, out of 100 cases, there were 58 cases of mild PIH (58%) and 42 cases of severe PIH (42%). Umbilical artery PI was elevated in 43(43.0%) patients and was normal in  57(57.0%) patients. Umbilical  artery RI was more than and equal to 0.7 in 77 patients  (77%) and was below of 0.7 in 23 (23%) pa-tients.9(9.0%)  fetuses showed  absence  and  14 (14.0%) fetus  had  reversal and 46 (46.0%) had reduced  end diastolic umbilical artery flow with total 69 out of 100  fetuses  having  abnormal  waveforms.65 (65%)  mothers  had  an  elevated  uterine  artery  PI   and  35(35%)  patients   had  normal uterine  artery PI. in observation 69 (69%)  patients  were  having  RI more  than 0.6, while 31 (31%) were having less than 0.6 out of 100 patients. In this study, 65 (65.0%) women were having persistent diastolic notch.

Conclusions: This study was to evaluate arterial flow velocities as a predictor of impending pregnancy induced hypertension with raised RI and PI along with umbilical ab-sent or reverse end diastolic flow velocities and elevated RI and PI in the presence of a diastolic notch are considered as abnormal uterine doppler findings doppler finding with unfavorable outcome.
