[A mathematical analysis of the flow-velocity curves in the femoral arteries].

In order to improve the early diagnosis of the aortoiliac injuries, 98 arteries from several supposedly health patients (different ages) and 41 femoral arteries from patients with occlusion at this level (demonstrated by arteriography) were studied. The analysis from the Fourier's series showed highly significant differences between both groups, and so did the comparison of some indexes automatically measured by the Vasoscan VL equip. By multivariant statistics methods was selected the main group of parameters that allows the differentiation between the ill patients and the healthy ones. This procedure can be useful for the physiopathological study and it may be used as a non-invasive method of diagnosis.
