title: Preoperative and Postoperative Evaluation of New Double Mesh Carotid Stents with Contrast-Enhanced Ultrasound and Diffusion-Weighted Imaging.
abstract: In this case series, we selected 4 patients with asymptomatic severe carotid stenosis due to unstable plaques, which were identified with contrast-enhanced ultrasound. These patients underwent carotid stenting with a new generation double mesh stent. Diffusion-weighted magnetic resonance imaging (DW-MRI) was executed before and after the procedure to detect early cerebral microembolizations. No early neurological complications occurred nor cerebral microembolizations were detected at DW-MRI. New double mesh carotid stents appear to be a safe option also in asymptomatic patients with unstable plaques at high risk for surgery.
