What is the most important thing that people with smog should know? The term smoker’s disease may not be familiar to people. It is a very rare cerebrovascular disease. The incidence is not high compared to conventional diseases, so few people know about it. Some people even think that the disease is caused by the smoke of secondhand smoke when they hear about it, but in fact, it has nothing to do with tobacco smoke, and it is named after a disease that resembles smoke in the imaging of the vascular network. Although cerebrovascular smog is a rare abnormal cerebrovascular disease at the base of the skull, the prevalence and incidence of the disease in China has gradually increased in recent years, and the impact of smog on daily life is also very great. It can cause headaches, dizziness, and lack of concentration, or it can lead to hemiplegia, aphasia, or even death! The treatment of smog has become a matter of urgency for patients. Some patients may ask: What is smog and how is it treated? Symptoms of smog: The symptoms of smog are mainly divided into cerebral ischemia and cerebral hemorrhage. Cerebral ischemia caused by narrowing of blood vessels can cause (headache, dizziness, lack of concentration). A heavier one may cause (numbness of limbs, weakness of limbs). If more severe, it may cause (hemiparesis and aphasia, etc.). Brain hemorrhage caused by excessive dilatation of blood vessels may cause (sudden severe headache with nausea and vomiting) and other symptoms. The main cause of death from smog is also due to cerebral hemorrhage. Also, smog can lead to cerebral infarction, which can cause (visual field defects, aphasia, etc.) That is, if you have the above symptoms, you cannot rule out the possibility of having smog. Smog is not self-curing: Smog is not usually self-curing, but surgical treatment is available. For example, direct bypass surgery, indirect bypass surgery (patch surgery), and the most common clinical option is combined vascular bypass surgery. (i.e. direct bypass surgery and indirect bypass surgery together) How to treat smog: Combined vascular bypass surgery is a combination of direct bypass surgery and indirect bypass surgery operated together. The principle of the surgery is to re-establish new blood flow channels to ensure adequate cerebral blood flow, and to rapidly improve the cerebral blood supply by anastomosing the intracranial and extracranial vessels through direct bypass. The extracranial blood supply-rich muscle and meningeal tissue are then applied to the intracranial surface of the brain. To alleviate the inadequate blood supply to the intracerebral arteries and improve the intracerebral blood flow by establishing a channel for the normal blood supply from the extracerebral vessels to the brain. It is the most used and most effective surgical treatment in clinical practice. It has the advantage of solving the problem of cerebral ischemia at once. The operation of the surgery is more operable and safe, and the effect of the surgery is maximized with immediate effect.
