Key result
Total arch replacement with the frozen elephant trunk technique for chronic aortic dissection resulted in a 6.7% hospital mortality and a 66.4% 5-year survival rate, but was complicated by distal stent-induced new entry in 33.3% of patients.
Why the study?
Although the FET technique for CAD provided good early results, short insertion length can induce dSINE requiring mid-term reoperation, raising questions about its surgical indication.

Does total arch replacement with the frozen elephant trunk technique improve outcomes in patients with chronic aortic dissection?
While the frozen elephant trunk technique for chronic aortic dissection provides acceptable early survival, it is associated with a high mid-term risk of distal stent-induced new entry (dSINE) requiring reintervention.
Substantial dSINE risk after FET warrants surveillance in chronic dissection; leaves open optimal repair strategy.
: The FET technique for CAD provided good early results. Short insertion length of the FET, however, can induce dSINE, which requires an additional operation at mid-term. Thus, surgical indication of the FET technique for CAD must be discussed.

Yamane et al. (2020) conducted an observational in Chronic aortic dissection (n=15). Total arch replacement with the frozen elephant trunk (FET) technique was evaluated on Hospital mortality. Total arch replacement with the frozen elephant trunk technique for chronic aortic dissection resulted in a 6.7% hospital mortality and a 66.4% 5-year survival rate, but was complicated by distal stent-induced new entry in 33.3% of patients.
