A Case of Carotid Artery Stenosis Complicating Scleroderma Treated by Carotid Artery Stenting

抄録

Objective: We treated a patient with carotid artery stenosis complicating scleroderma by carotid artery stenting (CAS) and achieved satisfactory dilation. Since scleroderma was suspected to have induced carotid artery stenosis, we report the case with a review of the literature.

Case Presentation: The patient was a 75-year-old woman diagnosed with scleroderma 8 years before. She thereafter developed polymyositis, liver cirrhosis, and stenosis of the bilateral internal carotid arteries; as progression of stenosis was observed, treatment was considered necessary. In consideration of the patient's general condition, CAS by the transbrachial approach was selected. There was no complication associated with the procedure, and satisfactory dilation could be achieved. No restenosis was observed 6 months after the procedure. The history of previous disorders and the results of antibody tests strongly suggested scleroderma as a cause of carotid artery stenosis.

Conclusion: We performed CAS in a patient with carotid artery stenosis suspected to have been caused by scleroderma and obtained a favorable outcome.
