Percutaneous carotid stenting with a distal-protection device is now considered an alternative to standard carotid endarterectomy. Although distal-protection filter devices have been reported to reduce the risk of embolism and stroke, their use is associated with such iatrogenic complications as vasospasm, dissection, and guidewire entrapment. Herein, we report a case of symptomatic carotid vasospasm caused by a distal-protection filter device during right internal carotid artery intervention in a woman who had underlying coronary artery disease. We also discuss the management of iatrogenic carotid spasm.
