title: Stent-graft Repair of a True Internal Thoracic Artery Aneurysm.
abstract: We present the case of a 49-year-old woman diagnosed with Sneddon's syndrome and previous endovascular embolization for cerebral and left renal artery aneurysms. The aneurysm was asymptomatic and incidentally detected as coin opacity at a preoperative X-ray performed for breast surgery. The 13-mm saccular left internal thoracic artery aneurysm engaged through a percutaneous left brachial artery access was successfully excluded with a stent graft. A 6-month follow-up computed tomography angiography confirmed the exclusion of the aneurysm, the patency of the internal thoracic artery, and the absence of endoleak or edge stenoses. True aneurysm of the internal thoracic artery is a rare entity. Stent-graft repair is a viable end effective alternative treatment for the exclusion of this lesion.
