[Value of rheoplethysmographic methods in the etiological diagnosis of leg ulcers].

Two recently introduced impedance plethysmographic methods have been used in the etiologic diagnosis of 100 leg ulcers: the occlusive rheoplethysmography (RPO) and the irrigraphy. RPO investigates the venous part of the lower limb circulation and irrigraphy the arterial blood flow. These two quantitative methods associated with Doppler examination of venous system allow to point out the type and the topography of the vascular alterations. The value of rheoplethysmographic methods in etiological leg ulcers investigation is reported.
