How many people are suffering from smog in China? How many people suffer from this disease? Smog is a rare disease, many people may not have heard of it, some do not know why, smog belongs to a kind of cerebrovascular disease, go to the hospital to consult the neurosurgery on the line. Although smog is a rare disease, but there is a certain geographical, like Europe, Africa and other countries incidence rate is lower than Central Asia, in Central Asia, the highest incidence rate of countries is Japan, and the concept of smog was first introduced in Japan, and other high incidence rate of Korea, China, etc., so smog in China compared to other countries or more, the number of people suffering from smog every year The number of people suffering from smog is increasing every year. In China, Anhui, Henan and Shandong are all regions with a high incidence of smog, and it is not excluded that other regions also have a high incidence of smog. Is smog hereditary? It is hard to say if the disease is hereditary, but if someone in the immediate family has the disease, the probability of having the disease is much higher than that of the general population. It is not certain that the disease is hereditary, but there is a chance that it will be. How is smog treated? Fortunately, there is a preventative treatment for smog, which is a very dangerous disease, and can be treated with bypass surgery. Smog bin bypass surgery is divided into three types of surgery, the most retired Akin is the joint vascular bypass surgery, the surgery is a combination of the other two bypass surgery, direct bypass and indirect bypass surgery together with the implementation of a surgery, so the combination of the advantages of the two surgeries, higher cure rate, less complications. Direct bypass surgery is to re-establish new blood flow channels to ensure adequate cerebral blood flow, and to rapidly improve cerebral blood supply by directly bypassing the intracranial and extracranial vascular anastomoses. Indirect bypass surgery, or patch surgery, involves patching muscle and meningeal tissue rich in extracranial blood supply onto the surface of the brain inside the skull. To relieve the inadequate blood supply to the intracerebral arteries, the blood flow in the brain is improved by establishing a channel for the normal blood vessels outside the brain to supply blood to the brain. After the blood supply is improved, the demand for smoke-like vessels will be reduced, thus reducing the risk of re-occurrence of cerebral ischemia and cerebral hemorrhage in patients. Combined vascular bypass surgery is a combination of direct bypass surgery and indirect bypass surgery, which means that both procedures are performed in the same operation, and is the most commonly used surgical treatment in clinical practice. The surgery provides a solid and powerful double guarantee of cerebral blood by re-establishing new blood flow channels and simultaneously applying extensive patches to the brain surface to induce the formation of new blood vessels. It is the most efficacious and safer surgical procedure. It has the advantage of solving the problem of cerebral ischemia at once. The procedure is more operable, safer, maximizes surgical results, and provides immediate results. It is generally the most recommended surgical procedure.
