It can be clearly said that for patients with cerebral thrombosis, if their condition is relatively stable, they do not need annual infusion. For the prevention of cerebral thrombosis, the main focus is on oral medication and elimination of some risk factors, such as improving the bad living habits, quitting smoking and limiting alcohol, eating a light diet, engaging in appropriate physical exercise, and controlling weight, these risk factors must be controlled. If there is a combination of hypertension, hyperglycemia and hyperlipidemia, these indicators must be controlled within a certain range through medication. Some drugs should be taken regularly, such as anti-platelet drugs, including aspirin and clopidogrel, and lipid-lowering drugs such as atorvastatin and resorvastatin. It is still necessary for patients with cerebral infarction to have regular checkups, such as annual laboratory tests, including routine blood tests, liver and kidney function, lipid and blood sugar monitoring, as well as cervical vascular ultrasound and transcranial Doppler screening, so that the changes of blood vessels must be monitored regularly. If there is severe stenosis or occlusion of blood vessels, timely treatment must be given. In conclusion, regular infusions are not necessary for stable conditions, but if acute changes occur, it is important to seek treatment at the hospital as soon as possible.
