Birth, old age, sickness and death are natural laws that no one can stop. Among these, birth, old age and death should be faced openly, except for illness, which can sometimes produce pain and suffering that can be unbearable. For example, a relatively rare cerebrovascular disease, smog, is very dangerous. Smoke disease, also called cerebral floor anomalous vascular network disease, is a malformed small vascular network disease formed by narrowing or occlusion of the main arteries of the brain followed by compensatory hyperplasia of the penetrating arteries at the base of the brain, which can cause cerebral ischemia, cerebral infarction, cerebral hemorrhage, seizures, etc., and in severe cases, even disability and death. Because the attack of smog disease may be very sudden, some may have a sudden onset without any signs, just as well as a sudden brain infarction, or a sudden brain hemorrhage, the light limbs numbness, dizziness and headache, the serious may be disabled, fatal, so the medical profession generally recommends that once the disease is clearly diagnosed as smog disease, surgery should be performed as soon as possible. This smog disease can only be cured by surgery, internal conservative therapy is generally of little significance, only a short period of relief of symptoms, the late effect is not good. The surgical treatment for smog is generally direct vascular bypass surgery, indirect vascular bypass surgery (also known as patching) and combined vascular bypass surgery. The combined vascular bypass surgery is generally considered to be the most effective, as it combines direct bypass and patching in the same surgery, which immediately achieves blood flow recanalization through direct bypass and rapidly improves the blood supply to the brain, while multi-factor patching is applied to the brain surface to induce the formation of neovascularization and further expand the scope of blood supply improvement. Some patients ask if smog disease can be reimbursed by the New Agricultural Cooperative. Yes, the New Agricultural Cooperative is able to reimburse, but it is necessary to go through the referral procedure and return to the local area for reimbursement according to the local policy.
