The Use of Intravascular Ultrasonography in Transcarotid Artery Revascularization Optimizes Stent Placement

Abstract

Transcarotid artery revascularization (TCAR) has been shown to have increasingly promising outcomes compared with transfemoral carotid artery stenting and carotid artery endarterectomy. At present, the standard practice is to obtain two two-dimensional angiographic views separated by 90° to evaluate stent deployment. Suboptimal stent deployment, poor stent apposition, or residual vessel stenosis are potential factors that can poorly affect the outcome. Postdilatation angioplasty can often correct these issues; however, it can be associated with a greater risk of embolic events.
