Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are well-established treatments that have been shown to decrease stroke recurrence in patients with underlying carotid artery disease. We assessed clinical outcome, safety, and restenosis rates for patients who underwent standardized CEA or CAS at our tertiary care center using patient selection criteria based on available scientific evidence. Retrospective chart review of patients who underwent CEA or CAS between 2009 and2016. In total, 314 cases (204 with CEA and 110 with CAS) were analyzed. Patients were predominantly white (84.4%), men (61.1%) with hypertension (86.9%) and hyperlipidemia (81.8%). Most patients (84.5%) had symptomatic carotid disease. No significant differences were observed in median postoperative National Institutes of Health Stroke Scale and modified Rankin scale (mRS) scores based on pretreatment symptomatic status or treatment modality (CEA vs. CAS). Most patients (85.9%) had favorable outcomes (mRS score 0-2) at a median follow-up of 11.7 months (interquartile range, 1.8-28.8). The perioperative complication rate was low (3.2%), and permanent neurologic deficit was seen in only 3 patients (1%). Restenosis was found in 7.3%, without significant difference between CEA and CAS at last follow-up. Restenosis was asymptomatic in most patients. Our findings in a real-world predominantly symptomatic cohort demonstrate that favorable patient outcomes and low restenosis and complication rates can be achieved with both CEA and CAS by the utilization of a consistent institutional patient selection and treatment process.
