The advantages of carotid artery stenting are short operation time, little trauma, and low anesthesia requirement; the disadvantages of carotid artery stenting are that carotid artery stenosis on the operated side may reoccur, and long-term oral antiplatelet aggregation drugs as well as drugs for atherosclerosis treatment are required. 1. Advantage: Carotid stenting, an endovascular intervention, is usually performed under the condition of cerebral hematography, where a stent is placed in the narrowed carotid artery segment through a catheter to relieve carotid artery stenosis and improve cerebral ischemia. The carotid artery is a large blood vessel, so the operation is relatively less difficult, shorter, less traumatic and faster recovery. 2. Disadvantages: Because stenting only opens up the stenotic carotid artery and does not resolve the plaque, there is still a risk of recurrent stenosis. In order to control this risk, it is necessary to take oral aspirin and clopidogrel hydrogensulphate to combat platelet aggregation, which is clinically referred to as the double antibiotic, as well as calcium atorvastatin or calcium reserpine to control atherosclerosis and stabilize the plaque. If carotid stenting is needed, it is recommended to go to a regular hospital.
