How long can I live after surgery for smoker’s disease? Smoker’s disease is a disease of the abnormal cerebral blood vessels at the base of the skull and belongs to neurosurgery. Smoker’s disease is a very dangerous disease that can be life-threatening. That is why it is important to have surgery early. Does smog affect life expectancy? The length of life of patients with smog disease depends on the age of onset, primary cause, severity of the disease, degree of brain tissue damage, and the speed of disease progression, etc. The length of life varies; some can live a lifetime without onset, while others may die of intracranial hemorrhage at a very young age. The mortality rate of smog is about 7.5%, including 10% in adult patients and 4.3% in pediatric patients, and there is no clear information on the relationship between smog and life expectancy. The main cause of death is cerebral hemorrhage, and surgical treatment can reduce the risk of cerebral hemorrhage. Surgery can reduce the risk of cerebral hemorrhage and thus protect the patient’s life. The clinical treatment of smog is based on direct bypass surgery, indirect bypass surgery, and combined vascular bypass surgery. Direct bypass surgery refers to the re-establishment of new blood channels to ensure adequate cerebral blood flow, through direct bypass to anastomose the intracranial and extracranial vessels and rapidly improve cerebral blood supply. Indirect bypass surgery, or patching surgery, is the application of muscle and meningeal tissue rich in extracranial blood supply to the surface of the brain inside the skull. To relieve the inadequate blood supply to the intracerebral arteries, the blood flow in the brain is improved by establishing a channel for the normal blood vessels outside the brain to supply blood to the brain. After the blood supply is improved, the demand for smoke-like vessels will be reduced, thus reducing the risk of re-occurrence of cerebral ischemia and cerebral hemorrhage in patients. Combined vascular bypass surgery is a combination of direct bypass surgery and indirect bypass surgery, i.e., two surgeries performed in the same operation, and is the most commonly used surgical treatment in clinical practice. It has the advantage of solving the problem of cerebral ischemia at once. The operation is more operable and safe, and the surgical effect is maximized with immediate results. Can smoker’s disease be cured: Smoker’s disease is a chronic progressive disease and there is no curative drug or surgical treatment available at this time. Because combined vascular bypass surgery cannot open the occluded cerebral blood vessels, it can only improve them, so in a strict sense, there is no cure for smoker’s disease. However, combined vascular bypass surgery is to re-establish new blood flow channels and to induce the formation of neovascularization to improve the lack of blood supply to the brain, and with neovascularization, the compensating vessels will not be overly dilated and cause brain hemorrhage, which can lead to death. Therefore, even if the occluded cerebral blood vessels cannot be opened, combined vascular bypass surgery is still possible to treat smog disease. According to a large number of clinical evidence, patients’ symptoms will be improved after the combined bypass surgery. It does not affect the patient’s normal life. Combined vascular bypass surgery is still the only effective treatment for smog. Patients should seek medical advice and arrange for appropriate surgical treatment if they have such a need.
