Given that cerebral thrombosis is recurrent and disabling and fatal, once diagnosed with cerebral thrombosis, regardless of the severity of the condition, it is necessary to take anti-thrombotic drugs for a long period of time to prevent the recurrence of cerebral thrombosis. The root cause of thrombosis is that irreversible lesions have occurred in the cerebral arteries. While the symptoms of cerebral thrombosis can be treated medically, the cause of the disease is difficult to remove. Only by taking aspirin and statins for a long period of time can the plaque in the blood vessels stop growing and reduce the possibility of its dislodgment, maintain the stability of blood flow and the stability of the patient’s symptoms, all of which can be achieved by taking anti-thrombotic drugs for a long period of time. Therefore, even mild cerebral blood clots need to be treated by taking medication for a long period of time.
