Abstract:
Obstructive atherosclerotic carotid bifurcation disease is responsible for approximately 30% of stroke cases in the United States. Any successful treatment of this disease should demonstrate significant and durable reduction in the related risk for stroke without compromising the patient safety. The indications for CAS are evolving as the techniques, the stents and catheter technology advance. There is an ongoing need to improve the equipment suitable for carotid stenting and a need to enhance the safety of the procedure. Often, when a technical problem is encountered, it is attributed to the inadequacy of the devices currently available. As the technology improves, particularly with the application of the anti-embolization devices, the indications and contraindication may need to be revised.
