Smoke is a relatively rare disease, and many people only hear about it for the first time when they are suddenly told they have it. Smoke and how to treat? In fact, smoke is a cerebrovascular disease, the patient’s brain on both sides of the main arterial vascular stenosis or occlusion phenomenon, the skull base secondary formation of a number of abnormal blood vessel network, because of imaging similar to the shape of the smoke, so the origin of the name. Usually, smoky brain is involved in both sides of the brain, meaning that both sides of the cerebral blood vessels have occurred corresponding lesions, of course, there are also some patients only unilateral lesions, which is medically referred to as smoky syndrome. Can unilateral smog disease become bilateral smog disease? Many people may think that smog disease is only unilateral lesions that is not less harmful, but in fact not so, unilateral smog disease is not timely treatment, with the development and deepening of the disease, it is possible to develop into bilateral. That is to say, whether it is unilateral or bilateral, the risk index is very high, so when the diagnosis is really confirmed, we should actively accept the treatment, to avoid the aggravation of the disease to cause greater harm to themselves. Many diseases can be treated with conservative or surgical treatments, but for smog disease, the significance of conservative medication is not very great, so experts in the medical field all agree that the treatment of smog disease still has to rely on surgical means.
