Smokers’ disease, this is a condition that many people may not have heard of. Indeed, it is a relatively new disease that was only discovered in the 1960s and has a very low incidence rate, making it a rare disease. Upon hearing the name of this disease, many people may associate it with respiratory diseases or lung diseases caused by smoking, which is misleading. In fact, smog disease is a very serious and dangerous cerebrovascular disease. It is caused by chronic progressive stenosis or occlusion of the major bilateral branches of the cerebral arterial ring, secondary to abnormalities in the vascular network at the base of the skull. The main dangers of Smokey’s disease are cerebral infarction and cerebral hemorrhage. There are also transient ischemic attacks, chronic ischemic symptoms in the brain, and seizures. So what are the conditions that predispose to the onset of smokers’ disease? Patients with smokers’ disease are prone to transient ischemic attack under the condition of emotional stress, crying, strenuous exercise or eating hot and spicy food, etc. The specific manifestations may include transient limb weakness, monoparesis, hemiparesis, hemiparesis, hemianopic sensory disorder, aphasia, monocular vision disorder, homonymous hemianopsia, and so on. Cerebral infarction, cerebral hemorrhage, seizures, etc., on the other hand, may tend to have little to no warning and can be very sudden, often triggering more serious consequences. Therefore, this also puts an urgent demand on the treatment of smog disease, once clearly diagnosed as smog disease should be treated as early as possible to avoid serious consequences. For the treatment of smog disease, combined vascular bypass surgery is currently an advanced treatment method. Through the combined use of direct vascular bypass and patching, a more ideal therapeutic effect can be achieved, which is absolutely beneficial to the improvement of cerebral blood supply of smog disease patients.
