In a short series of podcasts, we are going to explore the evolving field of complex thoracic aortic repair, with a particular focus on complex endovascular devices implanted in the aortic arch or even the ascending aorta, that is, zones 0 to 2. In today’s episode, we are going to dig into proximal landing zone 2, that is, the need to place the TEVAR device between the left carotid and the left subclavian arteries, so over the origin of the LSA, and strategies to preserve left subclavian artery perfusion.
