It is characterized by chronic progressive stenosis or occlusion of bilateral internal carotid arteries, anterior cerebral arteries and middle cerebral arteries, and secondary to the formation of an abnormal vascular network at the base of the skull, which manifests clinically as transient or permanent cerebral dysfunction symptoms. Smoke disease is very dangerous because of its high disability, recurrence and mortality rates. Smog not only affects the patient’s health, but also poses a threat to the patient’s life. If the disease is not treated effectively, most patients will exhibit frontal lobe signs and symptoms, such as dysarthria, aphasia, or hemiparesis. Other atypical symptoms, such as syncope, lower extremity diplegia, visual symptoms, or involuntary movements, may also be present. Some patients with a long history of the disease often present with bizarre behavior, manifesting as little speech, aloofness, impulsive rage, and paranoia. If the patient develops brain hemorrhage, it may pose a threat to the patient’s life safety. Therefore, smoker’s disease is seen in the hospital as early as possible, and the earlier the patient is treated surgically, the better the outcome. The treatment of smog disease requires the reconstruction of new blood flow blood flow channels to ensure adequate cerebral blood flow. Obviously, this new mode of treatment is not achievable with traditional medication and can only be achieved through surgical procedures. At present, combined vascular bypass surgery is a relatively advanced and effective surgical procedure, which can rapidly improve the cerebral blood supply by directly bypassing the intracranial and extracranial vessels to anastomose; at the same time, a large-scale patch is applied to the brain surface to induce the formation of neovascularization, which provides a solid and powerful double guarantee for cerebral blood supply. This not only improves the operability and safety of the surgery, but also makes the surgical effect of smog more remarkable. Because the surgery for smog involves craniotomy, the requirements for the selected hospital and specialist need to be a little higher, and the cost is usually not very high, requiring a specific evaluation at the hospital.
