What tests are done for smog? There are two main groups with high incidence of smog: first, children around 10 years old, children with smog will generally have confused speech, different degrees of headache and emotional irritability and irritability, etc. In addition, some children appear to be mentally retarded and slow to develop, part of the mental abnormalities, also need to go to the hospital to investigate whether it is caused by smog; second, adults around 40 years old, adults with early symptoms are more Early symptoms in adults are more obvious, such as different degrees of vomiting, dizziness, headache, numbness of the limbs, blurred vision, etc. Some patients also have more serious memory loss or general weakness, aphasia, epilepsy, etc. What tests are needed for smoker’s disease? Cerebral angiography (DSA) is the gold standard for diagnosing smog, which can reflect the morphological structure of cerebral blood vessels in a comprehensive manner with clear images and high resolution, providing a true three-dimensional pattern for observing vascular lesions and measuring the localization of blood vessel stenosis, further providing an accurate scientific basis for treatment. The essence of smoker’s disease is vascular lesions, and the specifics of vascular lesions cannot be seen by the human eye. CT angiography (CTA), magnetic resonance angiography (MRA), digital subtraction angiography (DSA), etc. can be used to diagnose smog. Digital subtraction angiography (DSA) is a high-end diagnostic technique that combines conventional angiography with computer technology, and DSA is the gold standard for the diagnosis of smog. Not only can the morphological structure of the blood vessels in the brain be clearly observed, it provides a true three-dimensional image of vascular lesions and the localization and measurement of vascular stenosis. It also provides an accurate clinical diagnosis by showing the narrowing or occlusion of the major bilateral branches of the cerebral arterial ring and the abnormal smoke-like network of tiny blood vessels at the base of the skull in patients with smog. Once the diagnosis of smoker’s disease is confirmed, joint vascular bypass surgery is recommended for timely treatment. One is direct bypass surgery, the other is patching surgery, also called indirect bypass surgery, and the third is a combination of these two surgeries, called “combined vascular bypass surgery”. This is because the probability of brain hemorrhage is higher in adults with smog, and if we simply use direct bypass or patch surgery, it is likely that brain hemorrhage will still occur during the surgery. For example, patching surgery takes 3-6 months to form new blood flow channels. And the probability of stroke is higher during this period. So the limitations are also greater. Combined vascular bypass surgery: Combined vascular bypass surgery is based on the advantages and disadvantages of the two traditional procedures, bypass + patching together in one surgery, based on the multifactor patching on the basis of bypass, the establishment of multiple blood flow pathways, to provide rich blood for the patient’s brain tissue, which can have the advantages of the patching surgery (a larger blood supply to the brain) and give the new blood vessels the time needed to grow (by the direct This gives the patient the advantage of the patching procedure (larger blood supply to the brain) and the time needed for the neovascularization to grow (normal blood supply is maintained by the direct bypass vessel) to avoid stroke before the neovascularization occurs. This is superior to direct bypass and indirect bypass alone. The surgery has a higher cure rate and less risk. Patients are advised to learn more and communicate with their doctors when choosing the procedure. A skilled physician will be able to better control the direction of the procedure and avoid unnecessary surgical risks.
