Quick spontaneous remodelling of thrombosed false lumen in acute type-A aortic dissection.

Natural history of acute Stanford type A aortic dissection (AAAD) implies the need of emergent surgical treatment in the vast majority of cases. Nevertheless, conservative treatment has been described to yield acceptable outcomes, when compared to surgery, in selected high risk cases of thrombosed false lumen. We report a significant quick remodelling of the false lumen occurred in an 85-year-old female 6 days after conservative treatment.
