Postoperative lymphedema is mainly caused by obstruction of lymphatic reflux, which is slow to subside, but can be slowed down by active treatment and improve the prognosis of the disease. Postoperative lymphedema may be caused by improper operation during surgery. Once lymphedema is formed, it is very difficult to be cured, but it can be controlled and slowed down by general treatment, medication and surgical treatment to gradually alleviate the symptoms. 1. General treatment: It is recommended to stop smoking and drinking, eat a light diet, regular work and rest, reasonable exercise, but also through hot compresses and other physical therapy to promote blood circulation in the edema, accelerate swelling. 2. Drug treatment: patients can take Diosmin, Herbaceous rhinoceros infusion tablets and other drugs to eliminate swelling. 3. Surgical treatment: when the effect of non-surgical treatment is not obvious, surgical treatment can be adopted to improve the prognosis of the disease. Lymphedema surgery can be divided into two categories: extensive resection of diseased tissue and reconstruction of lymphatic reflux. After standardized treatment, the progression of the disease can be slowed down to a certain extent, and patients are advised to relax and accept treatment actively.
