In recent years, with the significant increase in the incidence of smog in China, it has become a disease that is no longer extremely rare. Although the pathogenesis of smog is not yet fully understood, treatment is developing rapidly. Surgery has now been proven to be effective for the symptoms, cerebral infarction and cerebral hemorrhage caused by smog. There are various surgical procedures for smog, including direct bypass, indirect patching, and combined vascular bypass, all of which have the primary goal of improving the body’s already existing symptoms by increasing the blood supply to the brain. However, the results vary greatly depending on the principle of each procedure. Direct bypass is to connect the blood vessels on the scalp (e.g. superficial temporal artery, occipital artery) directly to the branches of the intracerebral arteries (e.g. anterior and middle cerebral arteries, or posterior cerebral artery, posterior inferior cerebellar artery). This procedure can effectively improve the blood supply to the brain, but the vascular anastomosis requires higher surgical skills, especially in pediatric patients, whose cerebral blood vessels are finer and more fragile, and the vascular anastomosis is more difficult; indirect bypass is to connect the extracranial (e.g. e.g., temporalis muscle, dura mater) blood-rich tissues are affixed to the brain, and usually in about 6 time, the vessels on these tissues will spontaneously anastomose with the cerebral cortex vessels, thus providing additional blood supply to the brain, but this procedure is not as effective for adults. Combined vascular bypass surgery is currently considered to be a more effective procedure for the treatment of smog. This procedure is a combination of direct bypass and indirect patching, which increases the blood supply to the brain through multiple channels and integrates to improve the results of the surgery, and has been widely praised by patients and their families. How much does the combined bypass surgery for smoker’s disease cost? It is understood that the combined vascular bypass surgery is operated under a high-precision microscope with high safety, and the cost is about 70,000-80,000, which can be consulted in detail at the hospital.
