Use of the frozen elephant trunk technique for type B aortic dissection and aberrant right subclavian artery: an anatomic repair of the “arteria lusoria”

Abstract

Retrograde extension into the aortic arch occurs in 16.5% of patients with type B aortic dissection (TBAD) (1). This cohort of patients may be eligible for a radical repair using the frozen elephant trunk (FET) technique. The combination of surgical replacement of the aortic arch and deployment of the stent graft allows complete exclusion of the false lumen in aortic dissections. In the case of aneurysm or residual dissection, patients undergoing FET are ready for subsequent endovascular or surgical treatment (2).
