Peri-procedural brain lesions prevention in CAS (3PCAS). Randomized trial comparing CGuard™ stent vs. wallstent
Background: Aim of this study was to evaluate peri-procedural incidence of new diffusion-weighted-magneticresonance-
imaging (DWMRI) brain lesions in CAS patients treated by carotid mesh stent (CGuard™) or
closed-cell stent (Wallstent™).
Methods: Consecutive patients with asymptomatic carotid stenosis ≥ 70% were submitted to preoperative DWMRI
scan, to exclude the presence of preoperative silent cerebral lesions. Patients were randomized to CGuard
orWallstent. DWMRI was performed immediately after the intervention and at 72-hour postoperatively. Moreover,
