Three-Year Clinical Results of Carotid Artery Stenting in Treating Patients with Contralateral Carotid Artery Occlusion

Carotid artery stenting (CAS) for patients with common carotid artery is a safe and effective therapy. Factors such as age 75 years or older and poor collateral are associated with a higher 3-year rate of postprocedural stroke, myocardial infarction and death, and lower event-free survival in patients with CCO treated by CAS. Meanwhile, our data do not show a significant impact of cerebral ischemic symptom and cerebral infarction history on clinical outcome of patients with CCO undergoing CAS.
