Smoky disease is an extremely rare disease, mainly due to the appearance of a cloud of smoke-like blood vessels during cerebral angiography, and is therefore known as smoky disease. The disease was discovered by Japanese scholars in the 1950s and 1960s, and has since been studied by experts from all over the world. The most distinctive feature of smog is the chronic narrowing or occlusion of the major arteries of the brain, so the focus of treatment for smog is on revascularization. In recent years, with the popularity of cerebral angiography, a certain number of cases of smog disease have been reported throughout the country. For example, many patients with smog disease have been encountered in the clinic, and some of them will ask how much does it cost to have smog bypass surgery? The traditional surgical methods for smog are direct bypass and indirect patching, but according to a large number of post-operative case summaries and studies, it is found that both have certain limitations and defects, and cannot achieve the desired results. For example, direct bypass can improve the blood supply to the brain in a short period of time, but the scope of blood supply improvement is limited, while patching is to patch the strong temporal muscle tissue to the skull base, and it takes 3-6 months to induce new blood vessel formation, during which there is still a risk of cerebral infarction. Our hospital has introduced combined vascular bypass surgery, which is an effective combination of direct bypass and indirect patching to form a composite procedure that can rebuild good blood flow channels to the brain and ensure blood supply to the brain, thus effectively preventing infarction and cerebral hemorrhage. At the same time, in order to improve the efficiency of surgery, our hospital regularly to invite domestic famous cerebrovascular disease experts and professors to operate in person, greatly improving the effect of treatment of smog; the cost of joint combined vascular bypass surgery needs to be decided according to the actual situation of the patient, the general cost is about 50-80,000, need also need to be determined according to the patient’s condition.
