　Carotid artery stenting (CAS) has advanced through improvements in devices, refinement of techniques, and better patient selection. Understanding the characteristics and appropriate use of each device is essential for maximizing procedural safety and outcomes. This review summarizes the features of major devices used in CAS—including balloon-guiding catheters, angioplasty balloons, distal embolic protection devices, and carotid stents—and discusses practical strategies for device selection based on lesion morphology and clinical context. In addition, we describe several technical tips and institutional approaches that have contributed to more stable and reproducible results in our practice. Although detailed troubleshooting and rare complications could not be fully covered due to space limitations, awareness of device behavior and potential pitfalls is crucial for preventing perioperative ischemic events. We hope this review helps clinicians refine their procedural strategies and contributes to further reductions in CAS-related complications.
