Carotid Stenting Can Improve Contralateral Perfusion and Function
Abstract

For patients with carotid artery stenosis, carotid endarterectomy and carotid angioplasty and stenting are two meth- ods 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 in- creasing 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.
