KSKwon–Duk SeoYonsei University TKT KimCatholic University of Daegu MSMinsoo SungYonsei University

Key Points

The study aims to examine the occurrence of new ischemic lesions after carotid artery stenting and their association with long-term functional outcomes.
Single-center retrospective analysis of symptomatic patients undergoing carotid artery stenting
Assessment of diffusion-weighted imaging for ischemic lesions post-procedure
Evaluation of clinical outcomes at 1-year follow-up
New ischemic lesions were frequently detected after carotid artery stenting
No significant association between these lesions and long-term functional outcomes
Periprocedural complication rates were low
Patients showed favorable outcomes at 1 year post-stenting

Abstract

New ischemic lesions on DWI were frequently observed after CAS but were not associated with long-term functional outcome. CAS was associated with low periprocedural complication rates and favorable 1-year outcomes in symptomatic patients treated at an experienced center.
