Major descriptors for arterial Doppler waveform were used to analyse waveforms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The proportion of multiphasic waveforms proximal to a moderate stenosis decreased compared to normal baseline, although the difference was not statistically significant, whereas the decreases at the stenosis, distal to the stenosis, and at the ankle were significant ( p &lt; 0.05). The decreases in arteries with a more severe stenosis or occlusion were significant at all locations ( p &lt; 0.05). The proportion of high resistive waveforms decreased significantly at the ankle in the arteries with a moderate stenosis (50%) ( p = 0.002), but the decreases proximal to, at, and distal to the stenosis were not significant. The decreases were significant at all locations in the arteries with a more severe stenosis ( p &lt; 0.05). The decrease was significant at the ankle in the arteries with an occlusion ( p &lt; 0.001) but not significant pre, at, and post an occlusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Phasicity and resistance of Doppler waveforms alter in canine femoral arteries with a stenosis.
