Changes of stent-graft orientation after frozen elephant trunk treatment in aortic dissection.

Objectives: Our goal was to evaluate the extent of stent-graft (SG) elastic recoil in the descending aorta after the frozen elephant trunk procedure in acute (AAD) and chronic (CAD) aortic dissection as well as the impact of SG movement on distal stent graft-induced new entry (d-SINE).

Methods: We retrospectively analysed 149 (105 AAD, 44 CAD) of 259 aortic dissection patients after the frozen elephant trunk procedure between January 2005 and April 2019. Inclusion criteria were at least 1-year computed tomography angiography (CTA) aortic examinations during a follow-up time of 3.

The impact of entries and exits on false lumen thrombosis and aortic remodelling.

Objectives: In DeBakey Type I acute aortic dissection, the frozen elephant trunk technique is used for the combined treatment of both the proximal and distal thoracic aorta. Anatomical characteristics of the distal aorta and their impact on false lumen (FL) thrombosis and aortic remodelling were analysed in this study.

Methods: Sufficient pre-, postoperative, and at least one 1-year follow-up computed tomography data sets were available for 63 of 94 patients treated with the frozen elephant trunk for Type I acute aortic dissection between March 2005 and March 2015.
