Association of Plaque Characteristics With New Ischemic Lesions After Carotid Artery Stenting.

ABSTRACT:

Background

Carotid artery stenting (CAS) is a common treatment for carotid artery stenosis, but it can lead to new ischemic brain lesions on diffusion-weighted images (DWI) during the perioperative period. Identifying these lesions early is crucial to preventing recurrent ischemic strokes.

Methods

This retrospective study included 47 patients who underwent CAS. Preoperative carotid PET/MR examinations and postoperative brain MRI were performed. Clinicians identified the responsible carotid artery based on symptoms and records. Vessel morphology, plaque characteristics, and inflammatory uptake were analyzed. The standardized uptake value and tissue-to-background ratio quantified ¹⁸F-fluorodeoxyglucose(¹⁸F-FDG) uptake. The symptomatic carotid atheroma inf
