title: [The strategy of thoracic endovascular repair for aortic arch aneurysms].
abstract: Thoracic endovascular aneurysm repair (TEVAR) has gained wide acceptance because of its minimal invasiveness and effectiveness for thoracic aortic aneurysms. However, the endovascular technique alone is often not applicable to arch aneurysms due to their anatomical complexity, such as aortic curve and presense of neck branches. The development of branched stent graft that allows total endovascular approach has been slow. Therefore open surgical technique is still needed to obtain an adequate landing zone. Prior total arch replacement with elephant trunk and debranching neck vessels including partial debranching such as carotid-carotid crossover bypass, and total debranching from the ascending aorta were able to create a suitable proximal landing zone. Chimney technique using covered stent for the neck vessels is also effective for arch aneurysms. Here, we report the strategies of TEVAR for aortic arch aneurysms.
