Is smoker’s disease a major illness? Nowadays, people always encounter some very strange diseases, the onset of which is very sudden and harmful, and it catches people off guard. For example, we often come across people with sudden onset of cerebral infarction or cerebral hemorrhage, the initial examination and can not find the cause, only to do further cerebral angiography only to find that the original is suffering from smog disease. Many people may not have heard of this disease, and even some grass-roots medical staff do not know what smog disease is. So, is smog disease a major disease? In fact, smog disease is essentially a cerebrovascular malformation, is a rare cerebrovascular disease, is due to the patient’s cerebral arterial ring bilateral major branches of the blood vessels have chronic progressive stenosis or occlusion, which led to the emergence of bilateral skull base vascular anomalies. It is evident that smog disease is quite serious, and if not treated and controlled in time, it will bring irreversible damage to the patient and has the possibility of causing death, so the patient should not pay attention to it. Generally speaking, smog disease only to take conservative drug treatment is not very effective, once a clear diagnosis of smog disease, it is necessary to go to the hospital in time to receive surgical treatment. The traditional surgical methods are usually simple patch or direct bypass, the treatment is not too comprehensive, the effect may be somewhat limited. Therefore, a more effective technique is needed to better treat smog disease. Director Yongjian Jin of the Department of Neurosurgery of Cerebrovascular Disease at China Medical University Aviation General Hospital has brought hope to patients. With nearly 30 years of experience and excellent techniques, he has successfully treated patients with combined vascular bypass surgery, and the postoperative recovery has been ideal.
