Smoker’s disease is a rare cerebrovascular disease that is caused by chronic progressive stenosis or occlusion of the major bilateral branches of the cerebral arterial ring, resulting in smoker’s malformation of the vascular network at the base of the skull. Because the disease is chronic and progressive, it starts at the beginning and develops slowly. The development of smoldering disease is generally divided into six stages: the first stage is the narrowing of the ends of the internal carotid arteries, most of which are bilateral, and a small number of which are unilateral. In the third stage, the end of the internal carotid artery is further stenosed and gradually involves the anterior and middle cerebral arteries, and the smoky vascular network at the skull base becomes more obvious; in the fourth stage, the entire cerebral artery ring or even the posterior cerebral artery is occluded, the extracranial collateral circulation begins to appear, and the smoky vessels begin to decrease; in the fifth stage, the compensatory blood supply from the extracranial to the intracranial increases, and the smoky vessels at the skull base continue to decrease; in the sixth stage, the smoky vessels at the skull base completely In the sixth stage, the smoke-like vessels at the base of the skull completely disappear, and the supply of cerebral blood is completely dependent on extracranial compensation. Of course the six stages described above are the complete course of smoldering disease, and this typical course of development is not experienced by everyone; it can stop at any stage. And any stage of its development is very dangerous and can easily lead to cerebral infarction or cerebral hemorrhage with serious consequences. If it progresses to stage 6, it is a very, very serious condition where the intracranial blood flow is completely oversupplied, the extracranial compensation is a drop in the bucket, the brain tissue is in a constant state of ischemia, and the probability of cerebral infarction is very high at this time. Therefore, once smog is detected and clearly diagnosed, regardless of its stage, it should be treated surgically as soon as possible, and it is impossible to think that it will heal on its own as it develops. The surgical treatment of smog disease is to reconstruct the intracranial blood flow channels and improve the blood supply to the brain. At present, the more advanced and effective is the combined vascular bypass surgery, through the direct anastomosis of the superficial temporal artery and the middle cerebral artery and the multi-factor vascular regeneration tissue patch, a two-pronged approach to complete a very good blood line reconstructed, to improve the intracranial blood supply has absolute benefits.
