Smoke disease is a very rare cerebrovascular disease, patients usually have headache and dizziness, weakness of limbs, aphasia, visual impairment and other symptoms, more serious patients will have brain hemorrhage. So why can’t you speak for four months after bleeding from smog? This may be because the patient with smog is undergoing symptomatic conservative treatment in the hospital, and the effect of medication is basically ineffective, there may be a situation similar to the above four months but still cannot speak. In this case, surgical treatment is very necessary, and a good choice of surgery will greatly relieve the symptoms of smog. The vascular bypass surgery and patching surgery currently performed in many hospitals have their own limitations and may not be effective in improving the patient’s condition. Combined vascular bypass surgery, which combines the two procedures, is a procedure that can be effective for patients with smog. Combined vascular bypass is an improved and enhanced procedure introduced from Japan. Combined vascular bypass is a combination of two traditional procedures performed simultaneously in one surgery to rapidly establish a trunk vascular circulation bypass through bypass and immediately improve the local blood supply, and at the same time, a multifactorial patch is applied to the brain surface to induce the formation of neovascularization and improve the brain ischemia to a greater extent. Since the joint vascular bypass surgery has been performed, many patients with smog have recovered and started a new life.
