Eight-year follow-up of endovascular repair of a brachiocephalic trunk aneurysm due to Takayasu's arteritis.

Abstract

Aneurysms of the brachiocephalic trunk are rare but their clinical outcomes are potentially devastating; they include rupture, cerebral or arm ischemia secondary to thromboembolism, and compression of the surrounding structures. Although open repair has proven successful, it is associated with significant morbidity and mortality rates. Endovascular treatment, if anatomically feasible, may offer a safer and less invasive approach to these lesions, especially in high-surgical-risk patients. We report the good long-term outcome of endovascular repair of a large innominate artery true aneurysm due to Takayasu's arteritis. A stent graft was safely and successfully deployed to exclude the aneurysm; assessment by vascular imaging at 8-year follow-up demonstrated the efficacy of the procedure.
