Atherosclerosis, a major cause of carotid artery stenosis, has a high correlation to stroke, which may induce transient ischemic attack (TIA) and/or permanent brain damage. The main treatment of carotid artery stenosis includes medication, carotid endarterectomy (CEA), and carotid artery stenting (CAS). However, when artery stenosis becomes severe, CEA or CAS is the most-often recommended intervention. CAS, a type of revascularization, is considered less invasive than CEA and is associated with a higher successful rate. CAS not only treats carotid stenosis effectively and reduces the incidence of stroke and myocardial infarction but also may increase the survival rate. Because CAS may lead to in-stent restenosis, an eluting stent has been developed to prevent this adverse event. However, the effectiveness of the eluting stent has yet to be adequately verified. As patients who receive CAS remain at risk of recurrent stroke, intravascular restenosis, TIA, and mortality, post-procedure medical and nursing care for this population must be appropriately applied in order to maximize the rate of long-term success. Therefore, we recommend that clinical physicians and nurses regularly evaluate and monitor post-CAS patients in order to prevent complications. Moreover, they should educate patients before discharge on post-CAS wound care and medicine-taking regimens as well as on the importance of smoking cessation, controlling blood sugar and blood pressure, exercising regularly, reducing body weight, maintaining a healthy diet, and controlling the risk factors of atherosclerosis in order to prevent the recurrence of complications.
