Can smog be treated with medication? To understand this question, it is important to understand where the cause of smog is. This will enable the right medicine to be prescribed. Smog can mainly cause cerebral hemorrhage and cerebral ischemia in patients. For the ischemic cause, vasodilators and anticoagulants can be used, and for patients with cerebral hemorrhage, hemostatic and antifibrinolytic drugs can be used. The allopathic treatment of internal medicine can only relieve the disease at the initial stage, but is not suitable for long-term treatment and has poor effect, therefore, it is not recommended to treat smog with drugs. The medical community generally believes that once diagnosed, smog should be treated surgically as soon as possible to improve blood supply to the brain before irreversible dysfunction of brain tissue occurs. This is the best way to treat smog. Surgical treatment of smog disease: For the surgical treatment of smog disease, the traditional surgical methods in China are direct bypass and patch surgery, but both of them have their defective types and limitations. Vascular bypass surgery can quickly establish blood flow side branch channels, improve local blood supply to the brain in a short time, and reduce the occurrence of ischemic cerebral blood supply, although the scope of improvement of blood supply is limited. In contrast, patching surgery can induce the formation of neovascularization to improve the scope of cerebral ischemia, but the formation of blood vessels requires a certain period of time, generally about 3-4 months, during which any risk of ischemia and patching surgery is the best treatment for pediatric patients, and there are a small number of adults who have difficulty forming neovascularization after patching surgery. The most effective treatment at this time is to perform both procedures together. The procedure is called a combined vascular bypass surgery. The advantages of the surgery: Direct bypass can immediately improve the blood supply to the brain for some patients who already have ischemic lesions, reduce the probability of morbidity and control the disease, and multi-factor patching can form good collateral circulation for about six months to improve the blood supply in a wide range of conditions, so the combination of the two is necessary. In patients with ischemic type, the formation of collateral circulation after surgery can meet a wide range of blood supply and reduce the complications of large area infarction, which will greatly reduce the probability of reoccurrence for both ischemic and hemorrhagic type. In conclusion: Smoldering disease can be treated with drugs, but it is not recommended. Combined vascular bypass surgery is currently the most effective surgical procedure for the treatment of smog.
