Wearing compression stockings after surgery is mainly used for post-surgical adjuvant treatment of varicose veins and other diseases of the lower limbs; indications exist and it is recommended to use them as prescribed by the doctor. When the human body is standing, gravity will cause a large amount of venous blood to accumulate in the leg veins, resulting in the atrophy and degradation of the venous valves, which makes it difficult for the venous blood to return to the veins. Compression stockings can promote the return of blood from the distal limbs to the heart by applying gradually decreasing pressure to the legs from the bottom up, thus preventing and treating venous diseases of the lower limbs. In the case of postoperative varicose veins of lower limbs, compression stockings can promote blood return to the lower limbs, enhance the valve function, reduce blood stagnation, and lower the recurrence rate of clinical diseases. In addition, compression stockings also play an important role in the prevention of postoperative lower extremity venous thrombosis and other diseases, and it is recommended that people at high risk of thrombosis choose to use them under the guidance of their physicians. Whether or not to use compression stockings requires comprehensive judgment by clinicians, and if the benefits outweigh the disadvantages, it is recommended that they be used in accordance with medical advice.
