Smoky brain disease is a relatively rare cerebrovascular disease, mainly cerebral arterial ring bilateral major branches of blood vessels (internal carotid artery end, anterior cerebral artery, middle cerebral artery, and sometimes including the beginning of the posterior cerebral artery) chronic progressive stenosis or occlusion, secondary to the formation of abnormal blood vessel network at the base of the skull, the newborn abnormal blood vessel network in the cerebral angiography presents a mass of a mass of smoke-like image, so the disease is figuratively known as smoky. This is why the disease has been visualized as “smog disease”. The harm of smog disease is very great, can lead to cerebral ischemia, cerebral infarction, cerebral hemorrhage, epileptic seizures, etc., found that the disease should be treated in time. Some people ask, smoke disease brain infarction large infarction can still be operated? The progression of smog disease is actually a competition between the gradual narrowing and occlusion of the major arterial branches and the gradual formation of compensatory vessels (smog-like abnormal vascular network) at the base of the skull, if the compensatory formation is fast, can meet the blood supply, then there may be no symptoms for the time being, but most of the time the narrowing and occlusion of the fast, the compensatory formation of the lack of cerebral ischemia, serious cerebral infarction, or even acute or large infarcts. This is very dangerous; in addition, the compensatory formation of smoke blood vessels is very thin and fragile, sometimes a slight fluctuation in blood pressure may lead to the rupture of these smoke blood vessels, causing cerebral hemorrhage; smoke lesions in the progression of the brain may also lead to abnormal brain discharges, resulting in epileptic seizures. These are very serious consequences, and sometimes may even be fatal, so it is recommended that smoky disease should be timely surgical treatment after a clear diagnosis. Then smog disease brain infarction large infarction can still be operated? Yes, it can, and it is very necessary. But just occurred after the acute period of large cerebral infarction, not suitable for smog disease surgery, generally need to wait for two or three months, cerebral infarction treatment recovery and stabilization before smog disease surgery.
