1 Clinical outcomes of thoracic endovascular aneurysm repair using commercially available fenestrated stent graft (Najuta endograft)  Shinichi Iwakoshi, MD, Shigeo Ichihashi, MD, Hirofumi Itoh, MD, Nobuoki Tabayashi, MD, Shoji Sakaguchi, MD, Takeshi Yoshida, MD, Yoshihisa Nakao, MD, Kimihiko Kichikawa, MD  Journal of Vascular Surgery  Volume 62, Issue 6, Pages (December 2015) DOI: /j.jvs Copyright © 2015 Society for Vascular Surgery Terms and Conditions

2 Fig 1 a, A man in his 70s with thoracic aortic aneurysm located at smaller curvature of the aortic arch. Thoracic endovascular aneurysm repair (TEVAR) with the Najuta endograft was scheduled. The red lines in this figure show the position of fenestrations. b and c, We prepared the Najuta endograft, which had three fenestrations, to preserve the brachiocephalic artery and left common carotid artery. We decided to occlude the left subclavian artery (LSA) because of the length from the origin of the LSA to the proximal end of the aneurysm. The second fenestration was for the brachiocephalic artery and the third one for the left common carotid artery. The first one was for backup in case of distal migration of the endograft. d, Contrast-enhanced computed tomography (CT) performed at 1 week after the procedure. e, Contrast-enhanced CT performed at 3 years after the procedure showed good sac shrinkage.

3 Fig 2 a, This Kaplan-Meier curve depicts the rate of freedom from secondary intervention after thoracic endovascular aneurysm repair (TEVAR) with the Najuta endograft. Actual estimations of the rate at 1 year and 3 years were 88% ± 5% and 84% ± 7%, respectively. b, This Kaplan-Meier curve depicts the rate of freedom from aneurysm enlargement after TEVAR with the Najuta endograft. Actual estimations of the rate at 1 year and 3 years were 96% ± 4% and 85% ± 8%, respectively.
