Whether the leg is weak after carotid artery stenting can be recovered or not should be analyzed according to the specific cause and severity of the disease, so it can not be generalized. If the lack of strength after carotid artery stenting is due to prolonged braking and lack of exercise or poor local blood circulation, recovery is generally possible. It can be treated with exercise and magnetic heat therapy. Carotid artery stenting may cause nerve dysfunction, or nerve dysfunction already existed before the operation, resulting in the patient’s leg weakness. If the nerve is only slightly damaged, it is possible to recover by applying nerve-nourishing drugs, such as methylcobalamin and B vitamins, as prescribed by the doctor. However, if the degree of nerve damage is severe, recovery is usually impossible. Rehabilitation treatment for leg weakness after carotid stenting needs to be carried out under the guidance of a doctor. In the early postoperative period, attention should be paid to braking and resting, and in the later period, gradual and progressive motor function exercise is needed to prevent after-effects. Usually pay attention to monitoring and controlling blood pressure, patients should quit smoking and drinking to prevent the recurrence of the disease in the later stage.
