Is smog a major surgery? At present, conservative surgical treatment for smog is not very effective, and surgery is more often chosen to treat smog. Smog can cause brain infarction, brain hemorrhage, etc., so there is a certain risk of death. The surgical treatment of smog is to prevent the risk of cerebral infarction and cerebral hemorrhage, so as to avoid death from hemiplegia. Some people may ask, “Since smog is such a terrible disease, there is no cure. So surgery must be a major operation, right? Isn’t it very dangerous? It is very normal for patients to have such doubts and and distress. It is because of the relatively conservative treatment philosophy of the Chinese people. The moment we talk about surgical treatment, we avoid it. They worry that the risk of surgery will have a great impact on them. In our clinic, we have a patient who did not want to have surgery and felt that the risk was too great and unnecessary, and eventually died because of this brain hemorrhage. So you see, the risk of smoke disease should never be underestimated. And the risk of this surgery is not as big a problem as people think. Next I will give you a detailed description of what the surgical treatment for smog is. There are three types of surgical treatment for smog, one is direct bypass surgery, one is indirect bypass surgery, and one is a combination of these two surgeries done together. We call it combined vascular bypass surgery. You can choose different types of surgery depending on the situation, but generally speaking, combined bypass surgery is recommended. This is the best and most effective treatment for smog. The clinical treatment options for smog are direct bypass surgery, indirect bypass surgery, and combined bypass surgery. Direct bypass surgery involves the re-establishment of new blood flow channels to ensure adequate cerebral blood flow, and the rapid improvement of cerebral blood supply by direct bypass to anastomose the intracranial and extracranial vessels. Indirect bypass surgery, or patching surgery, is the application of muscle and meningeal tissue rich in extracranial blood supply to the surface of the brain inside the skull. In order to relieve the inadequate blood supply to the intracerebral arteries, the blood flow in the brain is improved by establishing a channel for the normal blood supply to the brain from outside the brain. With the improved blood supply, the demand for smoke-like vessels is reduced, thus reducing the patient’s risk of reoccurring cerebral ischemia and cerebral hemorrhage. Combined vascular bypass surgery is based on the summary of the advantages and disadvantages of the two traditional procedures, bypass + patching in one operation, on the basis of bypass multi-factor patching, the establishment of multiple blood flow pathways, can provide rich blood for the patient’s brain tissue, this can have the advantages of patching surgery (the brain blood supply range is larger) and give the time needed for the growth of new blood vessels (by the direct bypass vessels to maintain normal blood supply). This avoids the development of a stroke before the neovascularization occurs. This is superior to direct bypass and indirect bypass alone. It is clear that the best surgical treatment for smog is a combined bypass procedure that takes the best of both worlds. The surgery has a higher cure rate and less risk.
