The dual-layer RoadSaver carotid stent was associated with 95.8% freedom from ipsilateral stroke at 12 months in an observational study of 100 high-risk patients, researchers reported. Freedom from restenosis and target lesion revascularization were 92.5% and 97.9%, respectively. (Eurointervention)
