Reversed end diastolic flow is more ominous than absent end diastolic flow. Presence of absent end diastolic flow and reversed end diastolic flow in umbilical artery is an ominous sign with high perinatal mortality. Oligohydramnios in PIH patients is associated with adverse pregnancy outcome. MCA PI had low specificity in predicting adverse perinatal outcome.Ĭonclusions: Pregnancy induced hypertension is associated with significant fetal morbidity and mortality.
Cerebroplacental ratio (MCA/UA) had highest sensitivity (94.42%), PPV (86.42%), accuracy (90%) for predicting adverse perinatal outcome than UAPI and MCA PI. UA PI has the highest sensitivity (88.88%) and positive predictive value (69.56%) in predicting low birth weight. Absent end diastolic flow waveform in umbilical artery was associated with mortality of 27.78% and reverse end diastolic waveform with mortality of 100%. Results: Adverse perinatal outcome was significantly associated with oligohydramnios (P <0.0001) and grade 3 placental maturity (P <0.01). The perinatal outcome results were documented and analyzed statistically using percentage and Chi-square test.
Methods: Hundred cases of women with pregnancy induced hypertension between 28-40 weeks of gestation were studied for umbilical artery and middle cerebral artery Doppler waveforms.
Background: Objectives of current study were to study the significance of Doppler in PIH using middle cerebral artery and umbilical artery blood flow and to analyze the role of Doppler in PIH in predicting perinatal outcome.
