CTICasesAortic Arch Aneurysm treated with TEVAR
Imaging findings
CT angiography shows a massive, leaking aneurysm of the aortic arch and descending thoracic aorta with hyperdense mural thrombus and calcification. Post-operative CT shows successful exclusion of the aneurysm using overlapping thoracic endovascular aortic repair (TEVAR) grafts, with a patent carotid-subclavian bypass.
Key takeaways
Leaking thoracic aortic aneurysms represent life-threatening emergencies. Endovascular treatment (TEVAR) is a highly effective, minimally invasive option. To secure an adequate proximal landing zone, surgical revascularization (such as a carotid-subclavian bypass) is often performed to allow coverage of the left subclavian artery origin.
