Smoke disease is a rare disease, a kind of cerebrovascular malformation, which is mainly caused by chronic progressive stenosis or occlusion of the main arteries of the cerebral artery ring, which leads to the appearance of small abnormal blood vessels. The new blood vessels are extremely fragile and can easily rupture and cause bleeding. Smog is an extremely dangerous disease, and the typical clinical case of smog is that the patient has abnormalities in both cerebral blood vessels, but in a few cases it is unilateral. In the treatment of smog, many small local hospitals can only take conservative medications, but the medications can only temporarily relieve some of the ischemic symptoms and cannot really improve the blood supply to the brain, so the treatment of smog should actually be surgical. Unilateral smoker’s disease only requires surgery on one side, but if both sides have abnormal changes in blood vessels, both the right and left sides must be operated on.
