Spiral artery blood flow in the central and peripheral area of placental bed in the normal third trimester by using color-doppler ultrasound

الملخص EN

- To assess the ability of colour/pulsed Doppler Ultrasound to assess the impedance of blood flow through spiral arteries in the central and peripheral area of the placental bed.

-This study has shown that there is statistically significant lower impedance values of blood flow in spiral arteries were obtained in central compared with peripheral area of placental bed, so we can compare the spiral artery flow velocity waveform in normal pregnancy and complicated pregnancies.
