ZALAQUETT, Ricardo et al. Aortic arch and proximal descending aorta replacement with the Thoraflex* prosthesis. Rev Chil Cardiol [online]. 2018, vol.37, n.1, pp.18-25. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602018000100018.

Atherosclerotic aneurysm or dissection of the aortic arch and proximal descending thoracic aorta is one of the major challenges for a cardiovascular surgeon. The new hybrid prosthesis Thoraflex has become an important devise to simplify the surgical treatment of this very complex and technically demanding aortic pathology. This hybrid prosthesis consists of a 4-branched arch graft with a stent-graft at the distal end. The proximal part is a gelatin-coated woven polyester prosthesis. The stented section is a self-expanding endoprosthesis constructed of thin-walled polyester and nitinol ring stents that is left in the proximal descending aorta as a “frozen elephant trunk”.

We present our initial experience with the Thoraflex prosthesis in four patients, three of them with chronic aortic dissection and one with an atherosclerotic aneurysm.

Palavras-chave : Frozen elephant trunk; aortic surgery; aneurysm; dissection.
