Peripheral vascular disease: carotid and vertebral brachytherapy for in-stent restenosis

Abstract

For years, intra-arterial brachytherapy has been a recognized method for treating recurrent stenosis after percutaneous transluminal angioplasty and stent placement. However, its use in arteries supplying the brain has not been described to date. We report a case treated with intra-arterial brachytherapy for high-grade recurrent stenoses of the high cervical internal carotid artery and the proximal vertebral artery. At 2-year follow-up, the outcome was successful.
