Smog is a rare disease. Smog is a rare disease that most people do not know about and at first hearing the name, they think it is a lung disease. In fact, smog is a cerebrovascular disease that is called smog because the image pattern resembles smoke when a cerebrovascular image is taken. Once a patient has smog, the main arteries in the brain become narrowed and the blood supply to the brain becomes abnormal, which is a very serious problem. Smog can be a serious problem, such as brain infarction and stroke, which are familiar to people. It can also lead to epilepsy, which can be very serious. Therefore, when you know you are suffering from smog, you must be careful and alert, and go to a regular hospital for treatment as soon as possible, so as to avoid the condition from expanding and bringing you more serious harm. The traditional treatment method is too single. At present, the treatment of smog mostly takes medication and surgery, but smog is not a disease that can be solved by taking medication alone, and long-term medication can also bring side effects, so it is recommended to take surgery for treatment. How long does it take to return to normal after surgery for smog? The traditional surgical methods are simple patching and simple direct bypass. Although these two surgical methods have certain effects on the treatment of smog, they are too single and the recovery after surgery is not ideal, and there may be recurrence, which is the reason why many patients cannot be cured for a long time. However, the treatment of smog in China has been greatly improved. We have widely performed combined vascular bypass for the treatment of smog for a large number of patients and have received high praise. It is understood that the combined vascular bypass was introduced from abroad, and after the team’s in-depth research and modification, the treatment effect has become more and more obvious, and we have completed more than 1000 cases of combined vascular bypass for smog disease, with definite efficacy and rich experience.
