The angiogram shows a dreamy ink painting, but people are not aware that it is a serious and rare cerebrovascular disease called “smog”. Smoker’s disease is a disease of cerebral hemorrhage or cerebral ischemia caused by stenosis of the end of the internal carotid artery, occlusion and abnormal vasodilatation network at the base of the brain, and the most common danger to people is recurrent transient paralysis or weakness, mostly on one side of the paralysis, and some patients have persistent paralysis, aphasia and even cerebral hemorrhage. Since the cause of the disease is still unclear and its progression is unpredictable, some patients may recover spontaneously due to improvement of cerebral ischemia by getting enough blood supply from the lateral branches. However, other patients have irreversible neurological dysfunction due to loss of compensation, so both conditions should be taken into account in clinical treatment. First, the main treatment is symptomatic. For ischemic onset, vasodilators and anticoagulants can be applied. For patients with cerebral hemorrhage apply hemostatic drugs and antifibrinolytic drugs, etc. For patients with epilepsy and involuntary movements it is appropriate to do the corresponding symptomatic treatment. Patients with cerebral hemorrhage with intracranial hypertension should have appropriate control of intracranial pressure. These operations can only play a role in relieving the patient’s condition and have little effect on the treatment of the disease. Second, before irreversible neurological dysfunction occurs in the brain tissue, the lateral branch circulation of the brain is increased by surgical methods to improve the blood supply to the brain and restore normal neurological function.
