Carotid artery revascularization in patients with contralateral carotid artery occlusion: Stent or endarterectomy?

In this exclusive large cohort of patients with contralateral carotid artery occlusion, CAS did not perform better compared with CEA in asymptomatic patients and had significantly worse outcomes in symptomatic patients in the perioperative period. The 2-year stroke rate was similar between the two procedures, but the risk of stroke or death was consistently higher for CAS patients. CAS is not safer than CEA in patients with contralateral carotid artery occlusion, and refinement of current guidelines is warranted to provide appropriate surgical care specifically tailored for the patient's presentation.
