Everyone is afraid of getting sick, but some diseases inevitably occur. In recent years, the incidence of smog has increased significantly, and many people do not know much about smog. At first glance, they think it is caused by smoking, haze and other problems, and some people even classify smog as a kind of lung disease. In the end, what is smog disease and can it be cured? There should be a question in the minds of many people. In fact, smog is a cerebrovascular disease, a more serious problem of cerebrovascular malformation. In patients with smoker’s disease, the main branches of the cerebral arterial ring become narrowed or even occluded, and when a cerebral angiogram is done, many tiny vascular networks are seen that resemble smoke, hence the name smoker’s disease. These tiny smoky blood vessels are very fragile and can easily lead to brain hemorrhage and cerebral infarction if not treated and controlled in time. In view of the great danger of smog, once the disease is affected, treatment should not be delayed in any way. So can smog be cured? The answer to this question is yes. Nowadays, medical technology is so advanced that the treatment of smog is no longer a problem. Patients should be in the right frame of mind and go to the hospital early to receive effective treatment. Generally speaking, the treatment of smog is divided into conservative treatment and surgical treatment. Conservative treatment is not very effective, and there will be recurrence, mainly because smog is a cerebrovascular occlusive disease, it is difficult to reverse the problem of blood vessel blockage by conservative medication alone, to really cure smog, you need to rely on surgical treatment.
