For symptomatic extracranial carotid artery stenosis (SECS) patients who cannot undergo early carotid endarterectomy, early carotid artery stenting (CAS) is effective and safe if selectively indicated considering disease severity. Early and delayed CAS provide comparable mRS scores, incidence of symptomatic thromboembolic complications, and intracranial bleeding with or without cerebral hyperperfusion syndrome (CHS) 1).
Treatment of CS consists of best medical treatment and carotid revascularization (CR), including carotid endarterectomy (CEA) and carotid artery stenting (CAS). Both CR techniques have their own procedural risks. Therefore, selection of the appropriate treatment for patients with CS is relatively complicated. Many studies and guidelines have reported the efficacy of each treatment for both symptomatic and asymptomatic patients. However, the results are still controversial, especially concerning the efficacy and safety of CEA and CAS 2).
