Smoke syndrome and smoke disease, there is no obvious difference between the two, both are named after the narrowing of the basilar arteries leading to insufficient blood supply to the arteries of the brain and the formation of abnormally fragile and tiny smoke-like vessels. Smog is a rare cerebrovascular disease that was discovered in the 1950s and 1960s. It is mainly caused by chronic progressive narrowing or occlusion of the major bilateral branches of the cerebral arterial ring (siphon section of the internal carotid artery, anterior cerebral artery, middle cerebral artery, and sometimes the beginning of the posterior cerebral artery), which subsequently leads to abnormal changes in the vascular network of the skull base and the formation of smoke-like vessels. Smog syndrome, also called smog-like disease, is a group of diseases that combine more than one underlying disease with smog. The pathogenesis of smog is still unclear, but in recent years, the number of patients and primary care physicians is increasing, and many patients and primary care physicians are deeply troubled by these diseases, which, at the same time, puts more stringent requirements on our experts and professors who are at the forefront of the medical field. Continuous exchange and learning and clinical practice is the way many doctors choose to improve themselves, and the best means of treating smog and smog syndrome, combined vascular bypass surgery, was birthed in this process, preventing the occurrence of short-term brain infarction in patients, and then growing in more capillaries on the surface of the brain, expanding the blood supply and saving countless patients with smog and smog syndrome. This is a medical advancement and a blessing for the majority of patients.
