[Carotid artery stenting with proximal and distal protection for radiation-induced carotid stenosis: a case report].

Here we report a case of radiation-induced carotid stenosis treated with carotid artery stenting and proximal and distal protection. A 62-year-old man with a history of radiation therapy for cervical malignant lymphoma at 31 years of age was diagnosed with left radiation-induced carotid stenosis. Angiography revealed left common carotid artery severe stenosis, and T1-weighted magnetic resonance imaging showed plaque hyperintensity. He was treated with carotid artery stenting and proximal and distal protection. Postoperative carotid ultrasonography showed moderate dilatation of the left common carotid artery and his postoperative course was uneventful. Carotid artery stenting and proximal and distal protection for radiation-induced carotid stenosis may be an effective treatment.
