Case ReportsSafety and utility of intravascular ultrasound-guided carotid artery stenting.
Intravascular ultrasound (IVUS) is useful in evaluating coronary stent deployment. The aim of this study was to assess the safety and utility of IVUS in carotid artery stenting (CAS). Ninety-eight consecutive high-risk patients (107 arteries) underwent CAS. ⋯ We found IVUS imaging in CAS to be safe even prior to plaque dilatation. IVUS provides a more accurate assessment of stent dimensions, expansion, and apposition than angiography. Severe calcification by IVUS was associated with a higher risk of stroke.
