Cerebrovascular disease is not uncommon, and the danger of this type of disease is relatively large, when they or their family members suffer from some kind of cerebrovascular disease, should be alert, such as smog disease. Although smog disease is relatively rare, but the harm of smog disease should not be underestimated, once diagnosed with smog disease must go to the hospital in time to receive professional and effective treatment. How do you get smog disease? In fact, the cause of smog disease is still unclear, some scholars believe that it is related to heredity, and some scholars believe that it is due to some acquired factors. From the medical analysis, the essence of the onset of smog disease is the patient’s cerebral arterial ring on both sides of the main branches of the blood vessels appeared chronic progressive stenosis or occlusion, which then led to the formation of some abnormal smoke-like blood vessels, these new blood vessels are relatively fragile, it is easy to rupture, causing cerebral hemorrhage. How long can I live with cerebral hemorrhage and smoky blood vessels? This is the patient and his family are more worried about, but this mainly depends on the size of the lesion and the location of the lesion, if the patient is only a small amount of cerebral hemorrhage, and active treatment to control, this will not affect the life expectancy. However, if the patient has a large number of brain hemorrhage or cerebral infarction, intracranial elevation is serious, etc., it will cause brain hernia or even death. In the clinic, the disability rate and death rate of smog disease is really high, so when the disease is diagnosed at the beginning, we must take active measures to treat it, and after the in-depth study of medical experts, a consensus has been reached that the conservative treatment of smog disease is not significant, and generally need to be surgical means in order to achieve a more ideal therapeutic effect.
