Abstract:
Objectives To evaluate the fetal blood flow velocity waveforms (FVWs) in relation to the perinatal outcomes. Methods 46 normal term pregnant women and 32 high risk pregnant women were examined with colour doppler ultrasound for their FVWs of umibilical artery (UmA). middle cerebral artery (MCA) and renal artery (RA). Results The resistance index (RI),pulsatile index(PI) and ratio of systolic to diastolic flow velocity(S/D) of UmA and RA were higher and the PI,S/D of MCA were lower significantly in the high risk pregnancy group than that of normal pregnancy group (P
