Smoker’s disease is a disease of abnormal cerebral blood vessels at the base of the skull. It is a condition caused by narrowing or occlusion of cerebral blood vessels, insufficient blood supply to the brain, and new small blood vessel branches growing out of the brain trying to reduce blood supply. In arteriography, the vascular network forms a disease that is named for its resemblance to smoke on the image. Smoke disease is a progressive, developmental disease with a high risk of cerebral infarction and cerebral hemorrhage. Many patients come to the hospital after having a brain attack or a brain hemorrhage to find out that they have smog. Therefore, it is difficult to distinguish the symptoms of smog. Some people may not have any symptoms of smog, or the symptoms may be mild and do not affect their normal life, so it is difficult to pay enough attention to them, but suddenly, one day, there is a brain infarction or brain hemorrhage, which is very critical, and the brain infarction or brain hemorrhage may lead to death if it is serious. This is the scary thing about smog, so when you learn you have smog, you must have surgery as soon as possible. Can a smog patient with a large cerebral infarction still undergo surgery for smog? The answer is yes, and it is very necessary. However, in the acute stage after a large cerebral infarction, it is not suitable for smog surgery. Generally, it is necessary to wait for two or three months, after the cerebral infarction treatment has recovered and stabilized, before performing smog surgery. For the treatment of smog, the current combined vascular bypass surgery has outstanding clinical effects. Combined vascular bypass surgery is a combination of traditional direct bypass surgery and patching surgery done together in the same surgery, through direct bypass of the superficial temporal artery-middle cerebral artery to rapidly improve the blood supply to the brain, and at the same time, multi-factor patching of the brain surface, including patching of the temporalis muscle, dura, skull periosteum, and middle meningeal artery, etc., to grow new blood vessels to the brain through a few months, further expanding the blood supply improvement This allows the brain to receive a better blood supply and return to a normal level of health.
