After stenting, patients with cerebral infarction may still have a tendency to relapse, so stenting does not mean that it is foolproof, and in the later stage, it is also necessary to take appropriate oral medications to maintain the relative effectiveness of stenting. In the clinic, stent is actually a foreign body, after stent surgery, it is just a foreign body placed in the corresponding blood vessel, in some cases, it will also form thrombus acutely, resulting in cerebral thrombosis, cerebral infarction recurrence, in the clinic, it is only a relatively small number of cases, but more in the later stage, if you don’t carry out the maintenance in time, the stent will still gradually form thrombus, resulting in the recurrence of cerebral infarction, and sometimes, other vessels are also in abnormal state, also need to take oral medication in time to maintain the relative effectiveness of the stent. Sometimes, other blood vessels are also in abnormal state, which can also lead to recurrence of cerebral infarction. Therefore, patients who have undergone stent surgery must follow the doctor’s instructions to take oral medication and undergo regular checkups, only in this way can it be more conducive to the improvement of the condition and reduce the probability of recurrence.
