Smog is a rare cerebrovascular disease that can cause cerebral infarction and cerebral hemorrhage, which is very dangerous and sometimes even life-threatening. That’s why many smog patients worry about life expectancy and ask how many years smog patients live to. Although smog is a very serious and dangerous disease, it can be treated surgically and well. The current highly respected surgical procedure for smog is combined vascular bypass surgery (traditionally bypass and patching), which is a surgical procedure that has evolved from both traditional bypass and single patching procedures. The direct bypass can introduce blood flow quickly and relieve symptoms with immediate effect; at the same time, the indirect bypass, i.e., multi-factor patching, will improve the blood supply environment to a greater extent, and the two-pronged approach can establish sufficient blood circulation to the brain to prevent cerebral ischemia, cerebral infarction and cerebral hemorrhage. Therefore, Professor Jin said, if smog disease is not treated, then it may develop at any time, and cerebral infarction, cerebral hemorrhage, or even life-threatening, and it is hard to say how many years old they can live. However, after effective treatment with combined vascular bypass surgery and restoration of cerebral blood supply, patients with smog disease can resume normal life without affecting their life expectancy.
