Smog is a rare cerebrovascular disease with a relatively low incidence. However, there has been a gradual increase in recent years, and more and more people are being screened for smog. When hearing the diagnosis of smog, most patients or family members may be baffled, as they may not have even heard of the disease. It is a cerebrovascular disease that was first discovered and named by a Japanese medical expert in the 1950s and 1960s. Smoke disease is caused by chronic progressive stenosis or occlusion of major bilateral branches of the cerebral arterial ring, which then leads to compensatory hyperplasia of the penetrating arteries at the base of the skull, forming a network of thin, fragile, smoke-like malformations that can easily lead to cerebral infarction or cerebral hemorrhage, with serious consequences. So can smog disease be cured? Smog is not an incurable disease, and smog can be cured clinically. Although it is a rare disease, the international and domestic medical community has been researching and exploring it for 60 to 70 years since it was first discovered, and has now developed a relatively complete and effective treatment method. In particular, the combined vascular bypass surgery carried out by Professor Jin Yongjian’s team at the Aviation General Hospital is an effective tool for treating smog. Professor Jin Yongjian introduced that although the combined vascular bypass surgery can not completely restore the anatomical structure of the brain blood vessels as normal people, it can provide sufficient blood flow to the brain to ensure normal function through blood line reconstruction, in this sense, it can be said to be a clinical cure for smog disease. Combined vascular bypass surgery is a combined procedure of direct bypass + patching. Through direct bypass, the main blood flow channel is quickly opened to immediately improve blood supply, while multi-factor patching is applied to the brain surface to improve brain blood supply in a larger area, with a two-pronged approach to achieve better treatment results.
