The carotid artery plays a pivotal role in the body, supplying 2/3 of the brain’s blood to the carotid artery. However, with the high incidence of carotid artery stenosis, a series of problems have followed. The risks associated with carotid stenosis cannot be underestimated, including transient cerebral ischemia, which is common, and ischemic stroke in some severe cases. In addition, there is a dangerous situation when unstable plaque may dislodge and enter the brain with blood flow, blocking the distal arteries and causing acute cerebral infarction, threatening the life of patients. Stenting is a common clinical treatment modality, however, after late follow-up feedback, some patients still have a high chance of reoccurrence of stenosis. At this point, a big question for the patient is undoubtedly whether to re-stent the carotid stent. For patients who have already undergone stent intervention and have a recurrent stenosis, re-stenting is strictly speaking not recommended. In addition to the fact that stent intervention may cause restenosis after surgery, it also requires long-term medication, which is a lengthy project for the patient. In addition, during the stent intervention, it may cause plaque dislodgement and form cerebral embolism, which further increases the difficulty of treatment. So, what should patients with carotid artery stent restenosis do? Medical science is changing rapidly, and the treatment of carotid stenosis is constantly improving. Currently, there is a gold standard for the treatment of carotid stenosis, namely carotid endarterectomy. This procedure has been clinically proven to be very effective in treating carotid artery stenosis and preventing cerebral infarction. Therefore, for patients with carotid artery stent restenosis, carotid endarterectomy is recommended to remove the stent, remove the plaque, and restore normal blood flow, thus effectively solving the various problems caused by carotid artery stenosis.
