What do you mean by smog? After many people have sudden limb numbness and aphasia, the hospital will first detect brain infarction and subsequently diagnose smog after some more careful examinations. Upon hearing the name, patients and their families are confused, having never heard of it and not knowing whether it is serious or not. Nowadays, the incidence of smog is slowly on the rise, which makes it necessary to deepen our knowledge of it, understand the symptoms, and understand the treatment options without being at a loss when it is detected. What exactly is smog? Smoggy disease was first discovered in Japan and is named after the many dense piles of small blood vessels that appear as smoke on cerebral angiograms. Some scholars believe that the disease may be caused by congenital factors, but some believe that it is an acquired cerebrovascular occlusive disease that may be related to metaplastic cerebral vasculitis. With smog, patients may experience transient ischemic attacks, recurrent transient hemiparesis or force weakness, and in severe cases, cerebral hemorrhage. Therefore, it is important to actively seek the most regular hospital, the most specialized doctor and the most effective surgery after the diagnosis of smog in order to prevent more dangerous situations from occurring. How is smog treated? After a long period of research and exploration, a lot of clinical practice has proved that conservative treatment is basically useless for smog, and surgery is the best treatment. Combined vascular bypass surgery was introduced from Japan, and after gradual improvement and refinement, it is already a very mature technology and has achieved very good results in clinical practice. The procedure is very safe because it does not involve brain tissue at all. By combining direct bypass and indirect bypass, it improves blood supply, creates new blood vessels on a larger scale, and establishes a smooth and sufficient blood flow channel, thus providing sufficient blood to the brain. Since the joint vascular bypass surgery was performed, more smog patients have been able to get out of pain and get a new life.
