Smog, many people may not have heard of it. But in recent years, with the development and popularity of medical imaging technology, more and more people are diagnosed with smog, and patients and their families cannot help but fall into panic and helplessness. So what is smog, and is it congenital or acquired? What is smog? Smoker’s disease is a relatively rare cerebrovascular disease that was first discovered by a Japanese scholar in the 1960s. In order to alleviate this blood supply disorder, the traditional arterial network at the base of the skull spontaneously and compensatingly proliferates, forming a network of small, fragile vessels that appear as a cloud of smoke on cerebral angiography, hence the name smog. Is there a congenital or acquired form of smog? There is no definitive answer to the question of whether smog is congenital or acquired. Clinical statistics show that there is a familial tendency to develop smog, with children or siblings of smog patients having a higher chance of developing smog than the general population. Some scholars believe that smog may be related to genetic factors, but there is no reliable evidence yet. Many scholars now believe that smog may be both congenital and acquired. How is smog treated? It is now generally accepted that conservative medical treatment is of little significance for smog, and that smog should be treated surgically as soon as it is clearly diagnosed. At present, combined vascular bypass surgery is a very advanced and effective treatment modality, unlike the previous patch surgery or bypass surgery, combined vascular bypass surgery is a kind of conforming surgery, combining bypass and patch in the same surgery, which can establish a more perfect blood flow bypass for the patient’s brain and better improve the patient’s brain blood supply, which can achieve very good treatment results and is highly recognized and respected by patients and their families. It is recognized and respected by patients and families.
