[Practical use of blood flow measurement with pulsed ultrasound in the 3d trimester of an at-risk pregnancy].
Using a pulsed Doppler technique measurements of blood flow of the arcuate artery, umbilical artery and foetal aorta were performed in the third trimenon in a group of 163 patients with risk pregnancies and compared with the weights of the newborn. In normal values of blood flow of the arcuate artery (n = 144) less than 10% of the weights of the newborn were below the tenth percentile. In pathological values (n = 19) about 42% newborn werde below the tenth percentile. In normal values of blood flow of the umbilical artery (n = 158) about 10% of the newborn were below the tenth percentile. In pathological values (n = 5) all newborn were below the tenth percentile. In normal values of blood flow of the foetal aorta (n = 139) about 12% of the newborn were below the tenth percentile. In pathological values (n = 4) all newborn were below the tenth percentile. Of the group with "normal" blood flow data a sub-group was formed with flow values between the first and second standard deviation. These were labelled "suspicious" and had shown a significant correlation with the birth weights of the newborn. Based on these experiences a schema was prepared comprising the blood flow measurements and cardiotocography, from which recommended clinical procedures were derived.
