Many people who first hear about smog are very nervous and scared, and when they hear that it is a rare disease, they feel that there is not much hope for treatment. Many patients with smoker’s disease are only discovered after brain hemorrhage, and smoker’s disease combined with aneurysm is also a key cause of bleeding. Subarachnoid hemorrhage. These patients may have clinical symptoms such as seizures and ischemia, and smog combined with aneurysms should be treated promptly once detected. If it is only smog, it is treated by combined vascular bypass surgery. This procedure, introduced from Japan, is currently the most effective procedure to treat smog. It involves direct bypass of the superficial temporal artery and the middle cerebral artery; the dura, temporalis, artery and cranial periosteum are applied to induce the formation of new blood vessels while continuously and comprehensively improving the blood supply to the brain tissue. This approach maximizes the effectiveness of the procedure, and the results are immediate, with patients generally experiencing a markedly perceptible improvement after surgery. The treatment of smog combined with aneurysm is usually done by craniotomy, endovascular embolization and combined vascular bypass.
