Successful Hybrid Endovascular and Open Approach for Exclusion of a Left Subclavian Artery Aneurysm.

Subclavian artery aneurysms are rare and challenging to treat owing to their anatomical location and proximity to critical branches, including the vertebral artery. We report the case of a 78-year-old man with a left subclavian artery aneurysm. The aneurysm was located in the mediastinum and measured 31 mm in diameter. The proximal side of the aneurysm was sealed with a stent graft, while the distal side was accessed through a supraclavicular incision and directly ligated. Postoperative imaging confirmed complete exclusion. This hybrid approach avoided invasive open surgery and provided a favorable outcome.
