Smog is essentially a progressive narrowing or blockage of the major arteries of the brain, which causes a range of clinical symptoms. What are the symptoms of smoker’s disease? Is it hereditary? What tests can be done to find out if you have smog? With these questions, here is a detailed introduction for you. What are the early symptoms of smog? It is found that the more common symptoms of smog are hemorrhagic symptoms and ischemic symptoms. Ischemic symptoms are mainly caused by the narrowing and occlusion of blood vessels, resulting in insufficient blood supply to the brain, causing dizziness and headache, weakness of limbs, memory loss, aphasia, etc. The most common hemorrhagic symptom is cerebral hemorrhage, which is often sudden and violent, and may cause patients to lose their lives if not treated in time. Can smog be hereditary? Although people have studied smog for more than half a century, there is still no definitive explanation for its specific pathogenesis. Some experts believe that the disease may be related to congenital genetic factors, as the pathology is found in individual families, but there is no adequate medical theory to make a proof. Another part of experts believe that it is a group of occlusive cerebrovascular diseases that develop later in life for various reasons. How can I be tested for smoker’s disease? In the medical field, any disease can only be diagnosed after a detailed examination. At present, the gold standard for the examination of smog is DSA, which has a high resolution and clear image display, and can comprehensively observe the vascular lesions and the degree of stenosis, which can provide an accurate basis for the scientific treatment of smog. How is smog treated? Pharmacological treatment for smog often uses vasodilators and anti-platelet aggregation drugs to improve symptoms, but the effect is limited, and long-term use of drugs may lead to cerebral hemorrhage. At present, the clinical development of combined vascular bypass surgery has opened a new door for the treatment of smog disease. Combined vascular bypass surgery is a combination of traditional direct bypass and multifactor patching, which rapidly establishes blood flow channels and rapidly improves local blood supply, while at the same time, large-area multifactor patching is applied to the brain surface to induce the formation of neovascularization and improve brain blood supply on a larger scale with outstanding efficacy.
