Endovascular management of carotid artery stenosis secondary to sclerosing mediastinitis.

Sclerosing mediastinitis is a rare, progressive condition characterized by extensive fibrotic reaction. We report the first known case of symptomatic, extrinsic compression of the carotid artery by fibrotic extension of sclerosing mediastinitis. A 54-year-old woman began experiencing neurologic symptoms from extension of a known mediastinal mass resulting in 70% to 79% stenosis of the right internal carotid artery. The stenosis was treated with endovascular stenting. Completion angiogram revealed a good result with <10% residual stenosis. At 18-month follow-up, the patient was symptom free without evidence of re-stenosis. Endovascular therapy provides a novel and durable solution in the midterm to this very rare problem.
