In many small places, due to limited medical equipment and inadequate medical staff, smog is easily misdiagnosed and underdiagnosed. Smog is usually detected only after the onset of symptoms. Patients usually go to a major hospital when they have a headache, dizziness, hemiplegia, weakness, aphasia, etc., and are then diagnosed with smog. When patients first hear about the rare form of smog, they are very unfamiliar with it and feel scared, but after occasional attacks, they have no more symptoms and wonder if they should be treated. As with all diseases, smog only progresses slowly and gets worse. It does not heal itself. During this period is very dangerous, patients are at risk of cerebral infarction or cerebral hemorrhage at any time and anywhere, and if it happens, there will be a risk of disability or even death. Therefore, in order to avoid such terrible consequences, smoker’s disease is in need of timely surgical treatment. Although smog is a rare disease, many hospitals are not able to guarantee the effect of the surgery, but the introduction of combined vascular bypass surgery has given hope to many smog patients, this surgery is a combination of domestic bypass surgery and patch surgery, and is better than two traditional surgeries, and has achieved very good results in the clinic, the smog patients treated by combined vascular bypass surgery have reached more than a thousand cases. Now they all get good recovery after the operation.
