Venous insufficiency, also know as venous reflux, is the impaired return of venous blood from the legs and feet, often manifesting as varicose veins, swollen ankles, aching legs, skin changes or venous ulcers in many cases, venous insufficiency is the result of over-dilation of the venous vessels in the legs. Deep vein valve reflux of the common femoral vein. Equally, when a patient suffers from deep vein thrombosis (dvt), deep vein reflux can occur, which means blood clots form in one or several of your deep veins – normally in your legsthe obstruction caused in dvt can lead to valve damage, which, in turn, causes venous insufficiency.
deep vein valve reflux of the common femoral vein
Valves within the veins of the legs help prevent the backflow of blood the most common causes of venous insufficiency are previous cases of blood clots and varicose veins. For example, the femoral vein has no functioning venous valve and so it is an incompetent system. there is a profunda femoral vein or great saphenous vein valve which is functioning. the incompetent femoral vein can be transected, ligated proximally and sewn into the competent venous system below the competent valve.. Included in the study were patients with deep vein reflux and symptoms of chronic venous insufficiency (ceap class c4–c6) who were not responsive to conservative therapies. once this had been established, these patients were treated with endovenous valve formation (evf) across five centres in australia, new zealand and canada..
