Ischemic Lesions in Diffusion-Weighted Imaging after Carotid Artery Stenting: Correlation with Access Route.

ABSTRACT:

Introduction

Despite recent advances in stents and stenting techniques, ischemic complications associated with carotid artery stenting (CAS) remain unresolved. Although plaque characteristics have attracted attention as risk factors, only a few studies have focused on access routes. This study aimed to identify ischemic factors following CAS, including access routes and plaque instability, using computed tomography angiography (CTA).

Methods

We retrospectively collected the clinical data of consecutive patients who underwent CAS and preoperative CTA. The access route was evaluated as having aortic plaques and a stenosis at proximal segment lesions beyond carotid plaques (brachiocephalic/common carotid artery). Aortic plaques were further classified based on the presence or a
