Venous insufficiency - Deep vein Thrombosis

Venous Insufficiency

The pathophysiology of chronic venous insufficiency comprises all the physical or functional abnormalities of the venous system caused by incontinence valve with or without associated venous obstruction, sitting at the superficial veins and / or deep veins. This venous dysfunction may be congenital or acquired. Varicose veins are the most common expression of dilated veins.

Symptoms

Venous insufficiency is a dysfunction affecting the network and venous valvular insufficiency. The venous stasis resulting leads hyperdistensibilité vein. The capillary resistance decreases, causing the installation of edema. This venous stasis increases the membrane permeability. The invasion by large protein molecules leads to elevated venous pressure (where water retention).

The functional signs are numerous and varying intensity. The most numerous are red, pain, heaviness and cramps. The heaviness and sluggishness sit, especially in the legs and calves (discomfort, tension). They are noted in 70% of patients with chronic venous insufficiency.

Doctors also note the phlebalgia (pain of a specific route venous), cramps (reflux valve), impatience (numbness appear in a stationary position, forcing the subject to mobilize or to stand if lying; syndrome restless legs where venous stasis rest is poorly tolerated and requires the muscle pump) and edema (bloating and tension).

Risks

These symptoms can provoke the appearance or the aggravation of the following risks: varicosities, varicose veins, dermatitis, varicose ulcers and the DVT (Deep Vein Thrombosis)
