When it comes to smog disease, many people will think of thick haze and dust, but in fact, it is not. It is a relatively rare ischemic cerebrovascular disease, and its disease has two peak age of onset, 1-10 years old and another 30-40 years old, and some patients have family history. The characteristic manifestations of smoker’s disease are spontaneous progressive occlusion of the internal carotid, anterior cerebral, and middle cerebral arteries proximal to the bed synapse, and a large number of reticular new collateral compensatory vessels with vascular abnormalities at the base of the skull. If smog disease is not treated early, most patients will develop present intellectual or motor dysfunction, repeated cerebral ischemia or cerebral hemorrhage, and as the disease worsens, the harm will become greater. Some patients do not take timely and effective treatment to control the onset of the disease, which can lead to a great impact on the physical and mental health of patients. Some patients with a long history of the disease often appear to behave strangely, manifesting themselves as less talkative, withdrawn, easily impulsive and irritable, and suspicious. The onset of the disease can affect inhalation, blood pressure and pulse rate, thus causing damage to the patient’s tissues and organs. Therefore, after the diagnosis of smog, patients should take effective treatment measures, that smog patch surgery effect is good? There are certain limitations in the treatment of smog with patch surgery, with a long period of effectiveness, during which it is easy to cerebral infarction phenomenon. For the treatment of smog, the industry currently promotes the “joint vascular bypass surgery”, a combination of patching and bypass surgery as a whole, bypass surgery can quickly supply blood in the short term, improve the symptoms and avoid the emergence of post-operative cerebral infarction, while multi-factor patching, can expand the scope of cerebral blood supply, greatly improving the therapeutic effect.
