Thrombo-occlusive vasculitis (hereinafter referred to as “vasculitis”) is a chronic and highly recurrent disease. Therefore, focus on prevention and care, reduce recurrence is an important aspect of the treatment of this disease. 1, quit smoking: According to the data, vasculitis has a history of smoking 60%-95%. Tobacco contains nicotine can cause small blood vessel spasm, resulting in vascular damage. 2, avoid hot and cold stimulation: according to statistics, vasculitis has a history of cold accounted for 57.9-80%, Chinese medicine believes that the evil of cold and damp can cause blood stagnation, blocking blood vessels, inducing the disease. Therefore, limb insulation is an important measure to prevent and relieve the disease. But ischemic limbs are strictly prohibited from high temperature soaking, hot compresses, physical therapy, etc., so as not to aggravate local tissue hypoxia, causing necrosis. 3, avoid trauma: trauma can damage the meridians, causing local stagnation of qi and blood, which is an important factor to induce or aggravate tissue necrosis. 4, regulate the emotions: Chinese medicine believes that the qi line is blood flow, qi stagnation is blood stasis, a variety of adverse emotional changes can lead to qi and blood stagnation, and induce the disease or aggravate the condition. So patients with vasculitis must maintain a good state of mind and optimistic mental state, the correct understanding of the disease, although the disease is difficult to completely cure, but can control the disease, relieve symptoms, reduce recurrence or not, to achieve clinical cure. 5, prohibit excessive sexual life, this disease patients more than the liver and kidney deficiency, and excessive sexual life will be more weak liver and kidney function, resulting in the aggravation of the disease. In addition, the disease is mostly male young adults, its onset may be related to male hormones, although not confirmed, but in clinical practice there are many examples of excessive sex and aggravation of the disease, so prohibit excessive sex is one of the important measures to control the disease. 6, adhere to the persistent treatment and moderate physical exercise. The disease has a long course, and can not be completely eradicated. Therefore, treatment should be persistent, according to the different severity of the disease, choose a different treatment plan, should not be in symptom relief, a long time to stop treatment, and the disease relapse. In addition, moderate physical exercise is an effective measure to promote the establishment of collateral vessels in the limbs, and patients should be encouraged to adhere to it for a long time. However, attention should be paid to the gradual progress, and the intensity and duration should not be excessive to prevent trauma and recurrence of the disease due to relative ischemia in the local area caused by excessive exercise.
