Abstract
PURPOSE: The frozen elephant-trunk (FET) procedure is used widely in total aortic arch replacement (TAR) surgery; however, its safety, effectiveness, and long-term outcomes compared with those of the conventional elephant trunk (cET) procedure for degenerative aneurysms are unclear. METHODS: Between July, 2011 and August, 2019, 126 patients underwent elective total aortic arch replacement at our institution. We compared the short- and mid-term outcomes of 60 patients who underwent the FET procedure (FET group) with those of 66 patients who underwent cET (cET group). RESULTS: The in-hospital mortality rate tended to be lower in the FET group than in the cET group (p = 0.12). There were two cases of paraplegia (3.3%) in the FET group and in none in the cET group. The all-cause mortality at the 3-year follow-up did not differ significantly between the groups (p = 0.31). The FET group required more unexpected interventions at the surgical site in the mid-term period. CONCLUSIONS: FET was associated with a shorter operative time and lower surgical mortality than cET. Although the mid-term total aortic arch replacement outcomes of FET were acceptable, careful imaging observation is necessary because reinterventions were required more frequently.
