Abstract
A prospective investigation was performed concerning the clinical value of Doppler examination with a flow velocity profile analysis using the quotient (AR) between the acceleration of velocity in a supposed diseased artery as compared with the acceleration of flow velocity in a healthy artery. Seventy-nine patients with peripheral arterial disease were followed at least one year after angiography which was performed as a preoperative examination. Comparing AR with angiography and blood pressure measurements it was found that AR values were affected favourably by development of good collaterals. AR≤0.25 (Doppler frequency 5 MHz) in the best artery of the foot was found in all patients where amputation had to be performed, and in 36 of 44 legs treated with vascular reconstruction.
