[Instrumental research of the functional character of the skin adnexa and microcirculation during chronic venous insufficiency]. / Recherche instrumentale du caractére fonctionnel des annexes cutanées et de la microcirculation au cours de l'insuffisance veineuse chronique (IVC).

We have led a microcirculatory and functional research of skin adnexa over 3 groups of 20 people each, who were affected with IVC at different grades and we have compared them to another group of 20 normal people. The microcirculatory researches (laser-Doppler, skin oximetry and thermometry) and functional ones of skin adnexa (sebometry and skin hydration) allowed us to get a nonunivocal behaviour between normal subjects and phlebopathies of I degree. For this reason, it is possible to consider these exams as screenings tests to determine the starting phases of phlebopathy, failing any skin marks. The reduced fluximetrical response taken by laser Doppler after postural variation and the reduction of hydration degree have been considered particularly significant.
