Classification criteria
We referred to the standard reported [17] for Thoracic Aortic
Endovascular Repair (TEVAR), and considered a significant change in
volume of more than 10% as one of the classification criteria. On this
basis, if the true lumen(TL) was enlarged (TL more than 10%), the false
lumen(FL) was closed or FL less than 10%, it was defined as positive
remodeling; the TL changed non-significantly (TL more than -10% and
less than 10%), and the FL changed less than 50%, partial thrombosis
or closed, was defined as stable remodeling; if the FL changed more than
50%, and the TL changed less than 10%, it was defined as negative
remodeling.
