A number of patients in the clinic ask what kind of disease is cerebral smoker’s disease and is it serious? Smoker’s disease is a rare disease worldwide. It is named by a Japanese medical expert because of the chronic progressive stenosis or occlusion of the major bilateral branches of the cerebral arterial ring, resulting in the growth of a network of tiny blood vessels in the side branches, which then appear like the smoke exhaled during smoking when a cerebral angiogram is performed. After years of research, the medical community found that this disease is a serious threat to human health and life. The danger of smoky disease 1, transient ischemic attack Transient cerebral ischemia is generally due to the narrowing or occlusion of the end of the internal carotid artery, the anterior cerebral artery, the middle cerebral artery, and sometimes the beginning of the posterior cerebral artery, resulting in the obstruction of blood flow and transient cerebral ischemic attack. The general manifestation is headache, limb weakness, blurred vision, etc.; 2, cerebral infarction Generally, after the occurrence of cerebral infarction, the patient is sent to the emergency medical service and the cerebral infarction foci are found by CT examination or MRI examination, and some patients also have limb disorder and aphasia symptoms, and the patient’s condition can be relieved after symptomatic treatment. 3.Brain hemorrhage The abnormal vascular network at the skull base of patients with smoker’s disease is very fragile and delicate, and when rupture occurs, it will cause brain hemorrhage, among which intraventricular hemorrhage and intracerebral hemorrhage are more common, while subarachnoid hemorrhage may occur from time to time, but it is relatively rare. For patients with these symptoms, cerebral angiography is recommended to further confirm the diagnosis, followed by surgery. In terms of results, combined vascular bypass has been shown to be ideal in the treatment of smog. The procedure is a direct bypass and a patching procedure performed simultaneously in one operation. The rapid improvement of cerebral blood supply is accompanied by the induction of neovascularization through multifactorial patching. By the two-pronged approach, the chance of cerebral infarction and cerebral hemorrhage is greatly reduced.
