Insuffisance valvulaire non post-thrombotique du système veineux profond des membres inférieurs

Abstract

Despite the fact that non post-thrombotic deep venous reflux is known for a long time, this syndrome is rarely identified as the pathophysiological mechanism responsible for chronic venous disease. The most frequent aetiology is the idiopathic deep venous insufficiency. In about 15% of the cases, superficial venous insufficiency, i.e., essential varicosities, is associated with an idiopathic deep venous insufficiency which may be responsible for varix recurrence despite treatment. In case of severe idiopathic deep venous insufficiency, surgery, in particular valvuloplasty, should be considered after conservative treatment failure. The procedure must be undertaken only after complementary investigations such as echo-Doppler, dynamic assessment of venous pressure, and phlebography have been performed.
