[Normal values of color Doppler ultrasound in pregnancy].
In addition to the flowmetrie of aorta fetalis and a. umbilicalis, color flow mapping enables the examination of the renal and middle cerebral arteries in the assessment of the fetal blood circulation. The resistance and pulsatility-indices of aorta fetalis, umbilical artery, renal artery and middle cerebral artery were calculated in a prospective examination of a normal study group of 123 pregnant women. Moreover, ratios were established from the pulsatility-indices of renal artery and aorta fetalis, renal artery and umbilical artery, middle cerebral artery and aorta fetalis, middle cerebral artery and umbilical artery. By the use of these ratios, we hope to detect more reliably changes in the fetal blood circulation.
