Fetal Doppler Indices in Predicting Perinatal Outcome Among Severely Hypertensive Pregnant Patients.

60 pregnant women with singleton living fetus between 34 -38 wks gestation known to have severe hypertension in the current pregnancy were included. All participants underwent Doppler ultrasonography to evaluate the Feto-Placental Circulation within 24 hours from Pregnancy Termination. Flow Velocity Waveforms were obtained from: Umbilical Artery (UA), Middle Cerebral Artery (MCA), Ductus Venosus (DV), Umbilical Vein (UV). From the flow velocity waveforms the following indices were measured: UA \& MCA: Pulsatility Index (PI) \& Resistance Index (RI), DV: Peak Velocity Index For veins (PVIV), Peak Systolic Velocity (PSV) \& a- wave. UV Flow: Presence or Absence of Pulsatile Flow.
