Smoker’s disease is a rare abnormal disease of the vascular network of the cerebral base, mainly due to chronic progressive stenosis or occlusion of the main branches of the cerebral arterial ring (the siphon section of the internal carotid artery and the anterior and middle cerebral arteries, sometimes including the beginning of the posterior cerebral artery), followed by the appearance of a network of small abnormal side branches. The disease is called “smog” because the cerebral angiogram shows many dense piles of small vessels, resembling the smoke exhaled during smoking. Is there a mature procedure for the treatment of smog in China? Smog was discovered in the 1950s and 1960s, and the first case was found in Japan. Since then, many medical experts have been exploring smog, and the treatment methods for smog have been improving. Nowadays, it is recognized that medical treatment is basically ineffective because it only aims at symptomatic relief, and the treatment is not effective in the long term. In addition, the two traditional surgical procedures in China, direct bypass and patching, have their own drawbacks and cannot achieve high efficiency. Faced with this dilemma, domestic smog patients and all cerebrovascular disease experts are worried, but this year, a new treatment means appeared, bringing new technology and the dawn of hope for domestic smog patients. This procedure has been continuously clinically summarized and technically improved, which has resulted in today’s combined vascular bypass surgery, which is a combination of two traditional surgeries with a two-pronged approach to improve blood supply to the maximum extent. Many of the patients and their families who have been treated for smog have given high marks to the combined bypass procedure.
