 note = {Objectives: The study aimed to evaluate the outcomes of total arch repair in patients with type I aortic dissection.
Methods: A total of 117 patients who underwent total arch repair over a period of 27 years were enrolled and divided into two groups: 75 patients who underwent total arch replacement （TAR） and 42 who underwent total arch repair using the frozen elephant trunk（ FET） technique. Univariate and multivariate analyses of outcomes were performed between the two groups.
Results: There was no significant difference in permanent cerebral dysfunction （5.3% vs. 9.5%） and temporary cerebral dysfunction （4.0% vs. 2.4%） between the TAR group and FET group. The 30-day and in-hospital mortality of TAR group vs. FET group were 6.7% vs. 0% （P=0.158） and 10.7% vs. 0% （P=0.049）, respectively. The overall survival was significantly higher in the FET group（ log rank P=0.034）. The long-term survival and aortic event free survival rates were not significantly different between the two groups. The independent risk factors for hospital mortality were age（ P=0.046）, preoperative hemodialysis（ P=0.003）, malperfusion of the carotid artery（ P=0.032）, and mediastinitis（ P=0.017）.
Conclusions: Total arch repair in patients with type I aortic dissection using FET was beneficial by educing the inhospital inhospital mortality and improving long-term survival rate.},
