After varicose vein surgery, patients are advised to wear antithrombotic gradient compression stockings for a period of 3-6 months. Anti-thrombotic gradient compression stockings are mainly used due to the pressure difference from bottom to top, thus producing a reflux-promoting effect on the veins of the lower limbs, as well as preventing thrombosis. Anti-thrombotic gradient compression stockings should be worn for a long time during the day or when it is difficult to stand, sit or walk for a long time. The anti-thrombotic gradient compression stockings can be removed at night while sleeping. It is important to consider that the life span of antithrombotic gradient compression stockings is about six months, and with wear and use, the elasticity decreases and new compression stockings are needed.
