Key result
The modified frozen elephant trunk technique for acute Stanford type A aortic dissection resulted in 0% hospital mortality and a significant increase in true lumen diameter distal to the stent graft at 3 months (p=0.01).
Why the study?
Acute Stanford type A aortic dissection is often fatal with no optimal standard treatment, prompting the description and short-term outcome evaluation of a modified frozen elephant trunk technique.
Does the modified frozen elephant trunk technique improve aortic remodeling in patients with acute Stanford type A aortic dissection?

Does the modified frozen elephant trunk technique improve aortic remodeling in patients with acute Stanford type A aortic dissection?
The modified frozen elephant trunk technique is safe and feasible for acute Stanford type A aortic dissection, promoting false lumen thrombosis and aortic remodeling at 3 months.
Song et al. (2020) conducted an observational in Acute Stanford type A aortic dissection (n=16). Modified frozen elephant trunk technique was evaluated on Changes in aortic diameters and short-term mortality. The modified frozen elephant trunk technique for acute Stanford type A aortic dissection resulted in 0% hospital mortality and a significant increase in true lumen diameter distal to the stent graft at 3 months (p=0.01).
