Saphenous varicose veins are most often caused by regurgitation of superficial venous blood flow due to incomplete closure of the first pair of valves in the superficial veins (femoral saphenous valves), which increases venous pressure in the lower extremities. Secondly, congenital weakness of the vein wall is also an important cause. Patients often have a combination of circumferential or restricted vein wall defects, which produce venous tortuosity and dilatation under increased venous pressure. Finally, factors such as prolonged standing, obesity, and abdominal pressure increase the possibility of varicose vein development due to increased venous pressure. The disease is a chronic disease and chronic disease mainly depends on maintenance, so regardless of the severity and whether surgery is performed, daily maintenance is very important and applicable to all stages, summarized in the following conservative treatment and health care methods: 1, elevate the legs and wear elastic stockings: elevate the legs so that the body position changes to help the venous blood return. Elastic stockings should be chosen from socks with high elasticity (medical), and the legs should be raised and slowly put into them before getting out of bed every day. The pressure of the elastic socks can improve and prevent varicose veins in the lower limbs. 2. Insist on wearing compression stockings, please put on the stockings before you get up and get out of bed every morning. Wear medical compression stockings when you go out to work or activities. 3.Keep the stockings clean and pay attention to whether the elasticity of the stockings changes. When the elastic stockings lose their elasticity, replace them immediately. 4.Avoid prolonged standing, walking and weight-bearing; when sitting for more than one hour, perform appropriate exercises such as tiptoeing to promote blood flow back to the lower limbs. 5.Elevate the lower limbs when resting, such as raising the bed leg 10-500px, or using soft pillows to raise the calf 10-500px; should develop a posture of lying down several times a day to raise the leg higher than the heart, so as to promote the venous circulation of the leg. 6.Do not use hot water above 40°C for a long time to soak your feet. 7.Keep your feet and legs clean and avoid skin breakage caused by trauma. 8, appropriate to drink more water to avoid blood concentration. 9, maintain a normal weight can not be overweight, because overweight will increase the burden on the leg veins. 10, every day to adhere to a certain amount of time walking, walking can play the calf muscle “muscle pump” role, to prevent the pressure of blood backflow. 11, quit smoking, because smoking can make the blood viscosity change, the blood becomes sticky, easy to stagnate. Oral contraceptives also have a similar effect, should try to take less. 12, standing health care: when standing, do not always use two legs together to support the weight of the whole body, can be focused, so that the two legs rotate rest. Often tiptoe, let the heel together with a drop activity, or often practice a few squats, can cause strong contraction of calf muscles, reduce venous blood accumulation. Walking frequently can also speed up the blood circulation of lower limbs and improve the symptoms of lower limb heaviness and pain of varicose veins in lower limbs. 13.Exercise health care: calf massage, kicking and holding knee exercise, standing foot exercise, bed exercise and fast walking, crawling exercise and tiptoe exercise, leg shaking exercise and other functional exercises can be carried out. Through these exercises can use the lower limbs of blood circulation back to accelerate, reduce the symptoms of venous stasis, enhance the function of the venous valve.
