Smog is a relatively rare disease, but the incidence of smog has increased in recent years. However, with the development of society and advances in medical technology, there are now excellent treatments for smog disease. Smoker’s disease is due to lesions in the bilateral branches of the cerebral base artery ring, which become narrowed or occluded. The main manifestations of smoker’s disease are: dizziness, headache, impaired limb movement, episodic aphasia and loss of intelligence and memory. If smog is not treated in time, there is also a possibility of cerebral ischemia or acute cerebral infarction because of prolonged stenosis or occlusion. Combined vascular bypass surgery is a better choice for treating smog, which is a combination of traditional direct bypass surgery and patching. The procedure rapidly establishes vascular collateral circulation channels and induces the growth of new blood vessels on a larger scale, thus improving the symptoms of cerebral blood supply deficiency. Some patients ask: How to take care of smog disease in general? Smoke disease can be treated by combined vascular bypass surgery and recovery is fast. After the surgery, patients should follow the doctor’s instructions, take rest, keep a happy mood and eat a balanced diet. We hope that all patients will be able to get out of their suffering soon, recover soon and stay away from the disease forever.
