1, first of all, patients should pay attention to the old rotten leg: early medical treatment, clear diagnosis and treatment, maintenance of improved venous reflux, clear tissue stasis, such as the history of venous ulcer, deep vein thrombophlebitis and venous valve insufficiency, more active treatment to prevent the development and aggravation of the disease. 2, avoid long standing, sitting and so on a posture: the human body long-term stationary standing or sitting, blood because of the role of gravity, so that the lower extremity venous valves under pressure, calf muscles in a relatively relaxed state, poor emptying of blood in the venous cavity, the valves continue to withstand the greater pressure. When the pressure is greater than the pressure resisted by the valve, the blood in the vein is abnormally refluxed and gradually aggravated, and finally the local venous stasis is aggravated. So should avoid long standing, sitting, should be appropriate rest, activity. 3, to prevent the long-term increase of intra-abdominal pressure: the increase of intra-abdominal pressure will affect the lower limb venous blood return, causing the lower limb venous pressure to rise, increasing the destruction of the venous valves or aggravating the burden of the venous valves. Therefore, diseases that lead to increased intra-abdominal pressure should be actively treated. 4, elevate the affected limb, promote the venous blood return to the lower limb: appropriate rest and elevate the affected limb, in order to promote the blood return to the affected limb, can reduce the swelling of the affected limb and prevent calf ulcers. The patient should elevate the affected limb 3-5 times a day for half an hour each time. Encourage walking to improve blood circulation. 5.Prevent trauma, because of venous tortuous: the vein wall is very thin and easy to damage rupture bleeding, so pay attention to protect the affected limb, avoid trauma frostbite or insect and animal bite. 6, old rotten leg combined with eczema: if combined with eczema should be treated in time to avoid scratching infection caused by ulcers or aggravation.
