This study aimed to report the clinical features and early and long-term outcomes of patients treated with carotid endarterectomy (CEA) combined with a routine shunt for carotid stenosis with the occlusion of the contralateral carotid artery (CCO), and to compare them with patients without contralateral occlusion (NO-CCO). A retrospective analysis included 301 patients who had carotid artery stenosis treated with CEA using a routine shunt. Of these patients, 35 patients and 266 patients were categorized into a CCO group and NO-CCO group, respectively. Demographics and short-term and long-term outcomes were documented and compared. The demographic characteristics were not significantly different between the two groups. The periprocedural mortality, stroke rate, and rate of periprocedural myocardial infarction were not significantly different between both groups. The mean follow-up period for long-term outcomes was 34.45 ± 22.99 months, and the Kaplan-Meier analysis showed no statistical difference between both groups regarding stroke, myocardial infarction, and mortality. CEA combined with the routine shunt is an effective and durable procedure for carotid artery stenosis patients with CCO.
