Résumé :

Mercury strain-gauge plethysmography venous mode is a non-invasive technique for exploration of the haemodynamics of the extremities. The plethysmographic parameters used are: (1) the venous inflow (in ml/100 ml/min); (2) the venous outflow (in ml/100 ml/min); (3) the venous capacity in ml/100ml; (4) the venous distensibility index in ml/100 ml/ mmHg; and (5) the venous pressure measured by ‘hysteresis curve’. This method permits us to analyse the venous haemodynamics of both extremities simultaneously (the normal limb serving as the control), to obtain a precise diagnosis and to appreciate the efficacy of treatment at follow-up. The aetiology of the swollen limb can be precisely identified in 95% of the studied cases: oedema in superficial venous insufficiency, oedema in the deep venous insufficiency, oedema of inflammatory origin, oedema in the arterial insufficiency, oedema of cardiac origin, lymphoedema. During the last 3 years, we have followed up 580 patients with this method. © 1987, SAGE Publications. All rights reserved.
