ABSTRACT
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.

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.

Se hace una revisión de la literatura en cuanto a los distintos procederes quirúrgicos utilizados en el manejo del síndrome postflebítico, llegándose previamente a la conclusión de que el único tratamiento racional es el quirúrgico. Se hace una clasificación fisiopatológica de los tratamientos quirúrgicos usados. Se concluye que no es posible la utilización de un solo proceder ya que los métodos más avalados por la experiencia no pueden ser utilizados en todos los casos. La conducta a seguir está determinada por cada caso particular y el resultado obtenido evidentemente está en relación con la experiencia acumulada previamente. Se hace una revisión estadística de 19 casos tratados por los distintos procederes y se enuncian los resultados obtenidos (AU)
