Abstract

  • Objectives The authors sought to study the characteristics and outcomes of patients with contralateral carotid artery occlusions (CCOs) undergoing elective carotid artery stenting (CAS).; Background CCOs are associated with adverse neurological events following carotid endarterectomy.; Methods In-hospital outcomes were examined in patients with and without CCO undergoing elective CAS in the Carotid Artery Revascularization and Endarterectomy (CARE) registry. A CCO was defined as a 100% occlusion of the contralateral internal carotid artery. To minimize differences in measured comorbidities, a 3: 1 propensity matching analysis was performed comparing 42 clinical and demographic variables between CCO and non-CCO patients from the CARE registry. The primary endpoint was a composite of in-hospital death, nonfatal myocardial infarction, and nonfatal stroke.; Results Between April 2005 and January 2012, 13,993 eligible patients underwent elective CAS, of whom 1,450 (10%) had CCO. There were 5,500 CAS procedures (1,375 CCO and 4,125 non-CCO) identified in the propensity analysis. The primary composite endpoint occurred in 29 (2.1%) and 107 (2.6%) patients with and without CCO, respectively (adjusted odds ratio: 0.81, 95% confidence interval: 0.53 to 1.23, p = 0.316).; Conclusions In the CARE registry, there was no evidence that the presence of a CCO was associated with an increased risk of in-hospital death, nonfatal myocardial infarction, or nonfatal stroke in patients undergoing elective CAS. These findings may have implications on the selection of carotid revascularization procedures for such patients.
