The name “smog disease” is easily misunderstood, and many people who hear about smog disease for the first time think that it is caused by air pollution, but in fact, smog disease is a cerebrovascular disease. In fact, smog disease is a cerebrovascular disease. After getting smog disease, the blood supply to the brain will be abnormal, which will lead to a series of uncomfortable symptoms in the body. From the clinical point of view, the onset of smog disease can be divided into ischemic and hemorrhagic these two, ischemic smog disease patients are mostly manifested as headache, dizziness, weakness, etc., and serious patients will also have limb activity disorders, or even hemiplegia phenomenon; and hemorrhagic smog disease onset is very acute, bleeding and not controlled in time, there is a risk of fatal. Smoke disease is not trivial, once the disease should be actively and effectively receive treatment. Currently, there are two main methods: medication and surgery, but medication can only provide temporary relief, but the long-term effect is not good, so from a long-term perspective, it is recommended that patients arrange for timely surgical treatment. Surgical methods include direct bypass, indirect bypass and combined vascular bypass surgery. However, after many medical practices, direct bypass and indirect bypass are still a bit single in treatment, and the postoperative recovery effect is not very satisfactory. What is the effect of combined vascular bypass surgery in treating smog disease? Compared with the previous two methods, combined vascular bypass surgery is very advantageous, the technology cleverly combines direct bypass and indirect bypass together, greatly improving the therapeutic effect.
