Background: Patients presenting a carotid stenosis and contralateral carotid occlusion (CCO) have been historically considered at high risk of carotid surgical treatment, and there are few data regarding short-term recovery after stenting therapy in patients with CCO. The aim of this study is to evaluate the short-term recovery and safety of stenting for patients with CCO and different subgroup population. Methods: We retrospectively reviewed the records of consecutive patients with CCO who were treated with stenting endovascular methods between 2008 and 2014. The postoperative outcomes were analyzed according to age, ischemic symptom, cerebral infarction history, and collateral situation subgroups, respectively. Results: Fifty-eight consecutive patients with CCO were treated and 49 (84.5%) completed a 3-year follow-up. There were significant higher stroke, myocardial infarction, or death events in the aged (>= 75 years old) group and poor collateral group (P =.007 and.0024, respectively). There was no difference in the 3-year primary endpoint incidence between the cerebral ischemia symptom subgroups and cerebral infarction history subgroups. Event-free survival, aged group, and poor collateral group were lower (P =.007 and P =.0024, respectively). Conclusions: 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.
