Table 2. Anatomical requirements for TER as reported by Czerny et al. [30]
Anatomical requirements N
Ascending aorta landing zone diameter (mm) 29-43
Distal landing zone diameter (mm) 19-43
BCT and LCCA diameter (mm) 7-20
ST junction to BCT length (mm) > 65 or > 85
Distal landing zone length (mm) 25-30
BCT landing zone length (mm) 25
LCCA landing zone length (mm) 30
Proximal BCT to distal LCCA (mm) < 45

BCT: Brachiocephalic trunk; LCCA: left common carotid artery; ST: sinotubular.

bypass grafting; TER: total endoarch repair.

the double-branched group and 16 (93.7%) patients in the single-branched group who exhibited TVP at 24
months postoperatively. 100% (n = 23) of patients in the triple-branched group maintained TVP during
[40]
follow-up . Alsafi et al. also report a 100% technical success rate in their smaller study of 21 patients
undergoing TER with RELAY™ Branched .
[41]
Azuma and colleagues report a 99.2% technical success rate in their cohort of 393 patients undergoing TER
with the fenestrated Kawasumi Najuta™ endograft . Sato et al. similarly report technical success in 97.3% of
[42]
patients treated with the Najuta™ device . The proximal landing zone was in Zone 0 for 86.1% of patients,
[43]
[43]
while Zone 1 was selected in 13.9% of patients . Iwakoshi et al. report a 91% success rate in their series of
32 patients undergoing TER with Najuta™ . Spear et al. report a very promising 100% technical success rate
[44]
in their series of 27 patients treated with the Cook Zenith™ endoprosthesis . The nonrandomized, single-
[38]
arm prospective study of 9 patients who underwent TER using the Valiant™ endoprosthesis by Roselli et al.
reported a 100% technical success rate .
[45]
Fujimura et al. highlight that TER with GORE TAG™ Thoracic Branched Endoprosthesis was anatomically
feasible in 40.8% (n = 87) of patients, while TER with Relay™, Najuta™, and Zenith™ was only anatomically
