Smoker’s disease is a very frightening cerebrovascular disease, which is mainly caused by chronic progressive stenosis or occlusion of the main branches of the cerebral arteries bilaterally, followed by compensatory abnormal growth of the penetrating arteries at the base of the skull, forming a network of tiny abnormal vessels, hence the name skull base abnormal vascular network disease. These abnormally enlarged vascular networks at the base of the skull appear as a cloud of smoke on cerebral angiography, which is why the disease is called smoky disease. The danger of smog is very serious and frightening. It can lead to cerebral ischemia, cerebral infarction, cerebral hemorrhage, and seizures. Early symptoms can include dizziness, headache, weakness of limbs, movement disorders, some patients show hand tremors, seizures, etc.; intellectual decline, memory loss, poor learning ability, abnormal vision and other symptoms. Some patients ask how can smog be cured to restore memory? Since the 1950s and 1960s, when Japanese scholars first discovered smog, the international and domestic medical community has been working tirelessly to research and explore the treatment of smog, and there are now very effective treatments available, and smog can be cured. Combined vascular bypass surgery is currently an ideal and effective means of treating smog. It is a compound surgery, which combines direct vascular bypass and patching in the same surgery. It can rapidly establish a blood bypass channel through direct bypass to rapidly improve cerebral blood supply, and at the same time, multifactor patching is performed on the brain surface to induce the formation of neovascularization and further expand the scope of improving cerebral blood supply, which has a more ideal clinical effect. After the treatment of combined vascular bypass surgery, the cerebral nerve function will be gradually relieved and restored after the brain blood supply is greatly improved by the two-pronged approach of direct bypass and patching, and the memory and intelligence will also be improved and restored to different degrees with it.
