Degenerative aneurysms of the thoracic aorta are increasing in prevalence. The recognition of the decreased morbidity of this approach compared with open repair was readily apparent, as it avoided left thoracotomy, aortic cross-clamping, and left heart bypass. ⋯ The cornerstones of successful thoracic endovascular aneurysm repair are appropriate patient selection, thorough preprocedural planning, and cautious procedural execution. Since then, TEVAR is increasingly being used for other aortic pathologies such as complicated type B dissection, traumatic aortic transection, and aneurysmal disease extending into the arch or visceral segment, requiring debranching procedures.

Acute aortic syndromes include aortic dissections, intramural hematomas, penetrating ulcers, ruptured or contained ruptured aortic aneurysms. In presence of acute thoracic or dorsal pain, elevated D-Dimers and if acute coronary artery syndrome has been ruled out, additional imaging should be performed to detect acute aortic pathologies. Acute type A dissections involve the ascending aorta. ⋯ They include adequate treatment of abdominal compartment syndrome, use of aortic stent grafts, endovascular balloon occlusion and permissive hypotension. Symptomatic complex aneurysms encompass renal and visceral arteries. Nowadays, they can be treated in an urgent setting using new endovascular techniques, such as "off-the shelf" branched stent grafts, parallel techniques, home made or in situ fenestrations of standard stent grafts.
