Results of Tailored CAS in Patients with High Risk Carotid Stenosis for CEA

Obejctive: This retrospective study aimed to compare the perioperative complications associated with treating carotid artery stenosis using either carotid endarterectomy (CEA) or carotid artery stenting (CAS) that were performed at a single Japanese institution from April 2011 to December 2014.Methods: CEA or CAS was selected to treat 222 lesions based on the patients’ individual risk factors. CEA was considered to be the first-line treatment in all cases (n = 104). The CEA group contained 55 symptomatic cases and 49 asymptomatic cases, and the CAS group contained 59 symptomatic cases and 59 asymptomatic cases. High-risk patients for CEA, which included, for example, those with angiographically poor collateral flows underwent CAS (n = 118).Results: The CEA and CAS groups were compared with respect to the perioperative clinical complications that occurred within 30 days of the procedures, which included any strokes, myocardial infarctions, or deaths. No significant differences were observed between the groups in relation to the perioperative complications.Conclusion: Selecting appropriate individualized treatment methods based on patients’ risk factors may contribute to improvements in the overall outcomes in patients with carotid artery stenoses.
