1 The compatibility of p-branch “off-the-shelf” fenestrated endovascular graft in Asian patients with juxtarenal aortic aneurysm  Jiale Ou, MBBS, MMed, Stephen W.K. Cheng, MBBS, FRCS (Eng), FCSHK, Yiu Che Chan, MBBS, BSc, MD, FRCS (Eng), FCSHK  Journal of Vascular Surgery  Volume 61, Issue 6, Pages (June 2015) DOI: /j.jvs Copyright © 2015 Society for Vascular Surgery Terms and Conditions

2 Fig 1 The design of the Zenith p-branch endovascular graft. A, Two versions of p-branch graft (left, option A; right, option B). B, Renal p-branch, lateral view and outside view. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2015 Society for Vascular Surgery Terms and Conditions

3 Fig 2 Three categories regarding the goodness of fit of the p-branch to the renal arteries: (A) perfect match; (B) marginal match; (C) mismatch. The three black circles represented the fenestrations of the SMA and the two renal arteries, and the rectangle was the scallop. The filled circles stood for celiac axis (green) and left (red) and right (blue) renal arteries. The size of the circles represented the actual diameter of the corresponding artery.

4 Fig 3 General positions of target vessels and their suitability with the p-branch grafts. A to D represent results in 26-, 28-, 30-, and 32-mm grafts, respectively. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2015 Society for Vascular Surgery Terms and Conditions

5 Fig 4 The applicability of the p-branch graft.

7 Fig 6 The match of graft length with abdominal aortic length. Four patients with abdominal aorta shorter than the graft length (dashed lines) were regarded as unsuitable candidates.

8 Fig 7 Comparison of applicability of the original design and the new design (with lower right renal fenestration of option B) of the p-branch stent grafts. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2015 Society for Vascular Surgery Terms and Conditions
