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

Although deep non post-thrombotic venous reflux in the lower limbs has been identified for several decades, it remains poorly recognized as a pathophysiological mechanism responsible for chronic venous disease. Primary deep venous insufficiency which is the most frequently observed type is combined with primary superficial venous insufficiency in about 15% of varicosities, and may be responsible for recurrences after their treatment. In severe cases, in case of conservative treatment failure, surgery, mainly valvuloplasty, must be considered after full investigations including duplex scan, ambulatory venous pressure measurement and phlebography.
