Management of expanding aortic arch aneurysm after hybrid endovascular and debranching repair

Hybrid procedures are used to treat aneurysms of the transverse aortic arch (TAA), combining debranching of the brachiocephalic vessels with endovascular approaches. Continued enlargement of the aneurysmal sac is a late complication. A 60-year-old man presented with an expanding transverse aortic arch aneurysm after prior hybrid repair and underwent left posterolateral thoracotomy, partial excision of the previous stent graft and replacement with an interposition graft.
