Smoke disease is a cerebrovascular disease and belongs to neurology. Some people ask which department to see for smog disease, smog disease should see neurosurgery. Because of the rare disease of smog disease, the medical profession recognized that the conservative treatment of internal medicine is ineffective, once a clear diagnosis must be cured by surgery, so it should be treated in neurosurgery. Of course, smog disease is a rare disease, not everywhere in the neurosurgery can be treated. Smokey’s disease is a group of cerebrovascular diseases characterized by chronic progressive stenosis or occlusion of the major bilateral branching vessels of the Circle of Willis (the siphon segment of the internal carotid artery and the anterior and middle cerebral arteries, and sometimes the beginning of the posterior cerebral arteries), with the secondary emergence of an abnormal side-branching network of small blood vessels. Because the cerebral angiography shows many dense piles of small blood vessel shadows, similar to the smoke exhaled during smoking, so it is called smoky disease. Therefore, intracranial and extracranial revascularization surgery is the main treatment for smog disease and smog syndrome, which can effectively prevent and treat stroke. At present, combined bypass surgery for smog disease can be said to be one of the most advanced and effective revascularization surgeries for the treatment of smog disease, which can effectively establish cerebral collateral circulation and improve cerebral blood supply through the combined use of direct bypass and patch surgery.
