Aneurysm of an aberrant right subclavian artery: treatment with thoracic aortic stent graft.

Abstract

Aberrant right subclavian artery aneurysms are rare but carry a high risk of spontaneous rupture without any treatment. Aggressive early elective treatment is warranted. We present a hybrid endovascular treatment that was used to treat a 77-year-old woman with aberrant right subclavian artery aneurysm for whom surgical treatment would have been associated with high risk. A thoracic stent graft was used to cover the origin of aberrant right subclavian artery at the proximal descending aorta. To prevent any retrograde flow, an Amplatzer septal occluder was deployed at the distal subclavian artery. Axillo-axillary bypass with an 8-mm polytetrafluoroethylene graft was performed due to atherosclerosis change of the common carotid artery to restore the right arm perfusion and prevent vertebrobasilar insufficiency.
