[Chronic venous insufficiency: prevention and drugless therapy].

The superficial and deep venous network of patients with chronic venous insufficiency is constantly undergoing change requiring careful follow-up and adapted therapy. Prevention, whether physical or medical, is recommended at all stages of the disease. The veins must be protected from factors which worsen venous abnormalities and drugs improving venous return should be prescribed. It is essential to avoid further aggravation of chronic venous insufficiency. The treatment has two objectives. First, and most important, to diminish or alleviate global or local venous hyperpressure which can be attained by surgery or sclerotherapy of venous leaking, via the crosses or perforating veins, into the superficial network. Venous hyperpressure can also be reduced by re-establishing normal venous haemodynamics with conservative techniques included elastic support or surgical techniques including CHI-VA. Finally, the second objective is to diminish or alleviate inaesthetic varicose veins and telangiectases.
