Emergent fully endovascular treatment of a free ruptured thoracoabdominal aneurysm.

To present a case of successful emergency complete endovascular repair of a ruptured type IV thoracoabdominal aortic aneurysms (TAAA) through chimney technique with off-the-shelf devices. A 64-year-old man with a free ruptured type IV TAAA. Open access was obtained at both common femoral arteries, both axillary arteries, and left common carotid artery. Covered stent grafts were located undeployed into the target arteries. An endoprosthesis was released in the suprarenal aorta, and soon after, covered stents were deployed in renal arteries and superior mesenteric artery. Type Ib and II endoleaks required an adjunctive endovascular treatment. Total endovascular repair with chimney technique may be the only life-saving option in patients unfit for open surgery and is effective in sealing the aneurysm and maintaining blood flow to the aortic branches.
