Fig 1 Actuarial survival curves. Five-year and 10-year actuarial survival rates were 84.4% and 84.4% in AAR group, 100% and 80% in TAR-R[–] group, and 100% and 100% in TAR-R[+] group, respectively, with no significant differences between groups.

Fig 2 Actuarial aorta-related event-free curves. Five-year and 10-year aorta-related event-free rates were 89.3% and 65.1% in the AAR group, 100% and 100% in the TAR-R[–] group, and 75% and 50% in the TAR-R[+] group, respectively, with no significant differences between the groups.

Fig 3 Status of late thrombosis in the remaining false lumen. (A) In proximal site (from distal arch to proximal descending aorta), a significantly higher patency rate was observed in the ascending aortic replacement (AAR) group (8 of 18 cases) than in the total arch replacement (TAR) group (1 of 17 cases; p = 0.009), including TAR-R[–] group (1 of 12 cases; p = 0.03). (B) In distal site (from distal descending aorta to abdominal aorta), there were no significant differences between the AAR and TAR groups. (TAR-R[–] = total arch replacement without resection of a primary tear; TAR-R[+] = total arch replacement with resection of a primary tear.)

Fig 4 Actuarial late aortic expansion (> 50 mm)–free rates at 5 and 10 years were 64.9% and 48.1% in ascending aortic replacement (AAR) group, 88.9% and 88.9% in the TAR-R[–] group, and 100% and 100% in the TAR-R[+] group, respectively, with a significantly lower rate in the AAR group (p = 0.04). (POD = postoperative day; TAR-R[–] = total arch replacement without resection of a primary tear; TAR-R[+] = total arch replacement with resection of a primary tear.)
