Health is very important, but now a lot of diseases “patronize”, people should pay more attention. Smoke disease is a more complex disease, the occurrence of smoke disease is mainly due to the patient’s brain on both sides of the main arterial stenosis or occlusion of the phenomenon, thus causing anomalies in the blood supply to the brain, secondary to the formation of abnormal blood vessel network at the base of the skull, untimely treatment will have a greater risk. There are many clinical examples of hemiplegia caused by smog disease, and there are even some patients who lost their lives as a result of a sudden cerebral hemorrhage that was not well controlled. Smoke disease is really dangerous. Once the disease is diagnosed, it is important to pay close attention to it and receive treatment at an early stage, so that the prognosis will be better. At present, many hospitals can only rely on conservative medication for the treatment of smog disease, but medication for smog disease is only a temporary relief of symptoms, which is of little significance in the long run. Therefore, the treatment of smoky skin disease still has to rely on surgical means, the traditional surgical methods are direct bypass or patch surgery. What happens when a patch procedure for smoky skin disease fails? There are a lot of patients in the patch surgery after the effect is not so ideal, this is mainly because in the patch surgery after the formation of blood vessels need about 3-6 months cycle, the probability of cerebral infarction during this period is still very large, and it is also true that some of the older patients may be ineffective in the patch, not able to grow neovascularization, so it is generally not recommended to simply use the patch surgery.
