[Variability of the indices of vascular resistance in carotid Doppler sonography. Study of influencing factors in healthy vascular probands].
In 83 test persons with healthy vessels within the Doppler sonography the resistance indices of the internal carotid artery and the supratrochlear artery were established and in the various regressor combinations with the help of the multiple correlation influences of age, pulse rate, systolic blood pressure and diastolic blood pressure as well amplitude of blood pressure were tested. Thereby only the combination of systolic blood pressure and amplitude of blood pressure proved to be relevant. The confidence limits of the PWI of the right internal carotid artery and of the supratrochlear arteries of the two sides were established so that in findings with limit value it is easier to be stated whether the changes are only caused by circulation or they are reference to underlying stenoses. There were no significances as to the sides of the peripheral resistance indices.
