There is a large primary tear feeding blood into the false lumen. The maximum diameter
of the thoracic aorta is only 46mm. This may be observed with serial CT monitoring but
future expansion is likely and eventual treatment (open or TEVAR) may be necessary, with
their respective mortality and morbidity.

Treatment at this stage with TEVAR is still controversial and not fully supported by good
evidence. The main limitation is the loss of remodelling potential as the dissection flap and

false lumen matures and hardens.
