Smog is a disease that people are not familiar with. It is a disease that always causes a lot of harm and makes people feel very painful and impatient about it. However, there are many different classifications of this disease, and right middle cerebral artery occlusion smog is one of them, which will be introduced here in more detail. Simply put, right middle cerebral artery occlusive smoker’s disease is a chronic progressive stenosis or occlusion of the major arteries of the brain on both sides of the patient. This results in the formation of a smoke-like network of abnormal vessels at the base of the skull. These vessels are very fragile and are susceptible to rupture and cerebral hemorrhage. In most cases, smoldering disease occurs bilaterally in the brain, but there are some patients who develop the disease on one side only, which is called smoldering disease syndrome. This is called smog syndrome, and once the disease develops, effective treatment is needed. Because medications can only temporarily relieve some of the symptoms on the surface, they cannot fundamentally solve the problem of blood supply to the brain. Therefore, surgery is the most effective way to solve smog. The traditional surgical methods are direct bypass or patch surgery, but clinical practice shows that these two methods have some limitations and shortcomings in improving the blood supply to the brain, so more advanced treatment techniques are needed.
