Smoker’s disease is a relatively rare cerebrovascular disease that is not common in life and many people have never even heard of it. It is actually mainly due to chronic progressive stenosis or occlusion of the main branch blood vessels of the brain, resulting in abnormal proliferation of the vascular network at the base of the skull, forming a fine and fragile network of small smoke-like vessels, hence the name smog. The most common symptoms of patients with smoker’s disease are mainly hemorrhagic and ischemic, manifested as headache, dizziness, weakness and numbness of one or both limbs, aphasia, hemiparesis, etc. Because smog is basically asymptomatic at the beginning, it is usually detected only when patients go to the hospital for examination. However, studies have found that the onset of smog has two distinct age peaks, mainly in children under the age of 10 and adults around the age of 40. But smog is not an incurable disease, as long as the correct treatment is taken in time, it can be cured. The current advanced surgery for smog is combined vascular bypass surgery, which is a direct bypass and patching at the same time, which can well establish the blood flow side branch circulation channel, improve the disadvantages of the blood supply range of a single bypass surgery, realize multi-faceted improvement of brain blood supply, and make up for the shortcomings of patching surgery, blood supply It can improve the blood supply to the brain in multiple directions, and make up for the disadvantage of slow blood supply by patching surgery, which greatly reduces the risk of re-infarction and cerebral hemorrhage of patients, thus effectively treating smog.
