A-F. Steps involved in modification of the Zenith fenestrated stent graft (Zfen). The device is already constrained posteriorly and comes with 2 fenestrations created by the manufacturer to accommodate the celiac and superior mesenteric artery. Modification requires only partial deployment of the graft (A). Fenestrations are created and reinforced as described in Fig. 5C. (A, B, and C). The device is collapsed with silastic loops (D) and resheathed (E). Follow up post-operative 3D CTA confirm continued aneurysm exclusion and patency of target vessels. Rationale for device selection: Zfen is by far the easiest device to modify as it is already constrained and modification only requires addition of desired fenestrations and resheathing. This is our device of choice for all elective cases
