Carotid Stenting Can Improve Contralateral Perfusion and Function

Abstract

For patients with carotid artery stenosis, carotid endarterectomy and carotid angioplasty and stenting are two methods that are effective in reducing stroke risk. These procedures have also been known to increase perfusion to the ipsilateral hemisphere and improve function; however, it is unknown if these procedures can improve function by increasing perfusion to the contralateral hemisphere. Longitudinal language assessment and neuroimaging data from this case study offers evidence that supports stenting of the contralateral common carotid artery and blood pressure elevation to improve collateral blood flow and, in turn, language performance.
