[Evaluation of the results of lumbar sympathectomy using hemodynamic variables].

In order to evaluate the results of the lumbar sympathectomy, we studied 49 patients in the National Institute of Angiology and Vascular Surgery during two years. The hemodynamic tests were performed the day before and one month after the surgical intervention; they included: skin thermometry, measurement of arterial blood flow and resistance in the foot and in the leg, and reactive hyperemia under photoplethysmographic control. Objectively, it could be seen only an increase in the distal skin temperature and an increase of skin blood flow after this treatment.

[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.
