The possibility of self-repair of the venous valve is very low and conservative treatment is required. The main conservative treatment is to exercise the calf muscles by wearing compression stockings. The compression stocking is a kind of medical elastic stocking, which is graded in pressure, and when wearing the stocking, the pressure is gradually reduced in the area from the ankle to the thigh. This is because the pressure gradient can effectively press the blood stagnant in the veins into the deep veins and promote blood circulation. The purpose of exercising the calf muscles is also to increase the power of the muscle pump. The contraction of the calf muscles allows the blood flowing in the veins to enter the deep veins quickly, also reducing the stagnation of blood in the veins. This reduces the pressure of the deep venous blood on the valves and can improve the patient’s symptoms.
