Carotid stenting in patients with cerebral infarction does not usually affect limb movement unless complications such as reperfusion injury, plaque bleeding or dislodgement occur. Carotid stenting, when successfully operated, improves cerebral blood supply and reduces the risk of recurrent cerebral infarction. When carotid stenting is performed in patients with cerebral infarction, if it leads to plaque bleeding, thrombosis, or plaque dislodgement in the carotid artery, it may cause a new cerebral infarction, resulting in compromised limb movement. In addition, after stent placement, the previously occluded carotid artery suddenly restores the smooth flow of blood, and the brain tissues that are already ischemic and necrotic due to infarction are suddenly supplied with blood, which may lead to reperfusion injury and induce cerebral hemorrhage, and may also affect the limb movement. Successful carotid artery stenting operation, if it is performed on a suitable patient with cerebral infarction, can have the effect of saving brain tissues that are not yet necrotic and reducing the risk of recurrence of cerebral infarction.
