Dizziness after stenting for cerebral infarction should be considered whether stent thrombosis occurs or whether stent expansion is good, and whether there is new intracranial stenosis. 1. Stent thrombosis: if dizziness still occurs after stenting for cerebral infarction, the first thing to consider is whether stent thrombosis has occurred. Ask the patient whether he/she has taken double antibiotics (such as aspirin, clopidogrel, tegretol) at regular intervals after stenting, and if necessary, review the thromboelastography to assess the possibility of stent thrombosis. 2. Whether the stent expansion is good: If the dizziness is severe, cerebral angiography can be repeated to observe whether the stent expansion is good and whether it is in place. 3. Newly developed intracranial stenosis: If the patient has other symptoms in addition to dizziness, such as limb weakness, speech disorder, etc., it is necessary to consider whether there is new intracranial stenosis resulting in intracranial ischemia. It should be noted that some cerebral infarcts cause permanent nerve damage and central vertigo, and the symptoms of dizziness do not always disappear completely with successful stenting. After cerebrovascular stenting, it is important to take medications (e.g., aspirin, clopidogrel, tegretol) at regular intervals as prescribed by your doctor, and to have follow-up examinations on a regular basis. If you have any obvious discomfort, you should go to the hospital in time to find out the cause, so as to avoid further damage due to the prolongation of the disease.
