Smog is a disease whose cause is still unknown, and some scholars speculate that it may be related to genetic or acquired metaplastic cerebral vasculitis, two theories that have not been effectively confirmed. Smoky disease was first discovered in the late 1960s when a Japanese scholar performed a cerebral angiogram and found that the shape of the image displayed looked like smoke just coming out of a chimney, which led to the name smoky disease. Smog is known as a rare disease, and is thought to be so to this day. Since the 21st century, with the improvement of China’s comprehensive strength in medical research and the emergence and popularity of medical imaging technology, the number of clinical cases of smog has been increasing day by day, and more and more patients and doctors have started to pay extra attention and be alert to this disease. After years of clinical research and summary, doctors found that the greatest impact of smog is cerebral ischemia and cerebral hemorrhage, so the treatment of smog should also start from comprehensive improvement of cerebral blood supply, layer by layer, to establish sufficient cerebral blood circulation system, so that the microenvironment of the lesion can be effectively improved, thus achieving a cure for smog. At present, combined vascular bypass surgery uses both direct bypass and indirect patching, which can establish a wide range of cerebral blood supply through a variety of ways, and the effect is very excellent. What is the cost of smog surgery in Zhengzhou? The cost of smog surgery varies from person to person and is determined by the condition, and varies from individual to individual.
