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 1417-1423 (June 2015) DOI: 10.1016/j.jvs.2014.12.061 Copyright © 2015 Society for Vascular Surgery Terms and Conditions

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.

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.

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.

Fig 5 Suitability of renal fenestrations, scallop, and graft length. Journal of Vascular Surgery 2015 61, 1417-1423DOI: (10.1016/j.jvs.2014.12.061) Copyright © 2015 Society for Vascular Surgery Terms and Conditions

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.

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.
