1 Stent misalignment of the Zenith Dissection Endovascular System
Luca Bertoglio, MD, Germano Melissano, MD, Efrem Civilini, MD, Roberto Chiesa, MD  Journal of Vascular Surgery  Volume 57, Issue 2, Pages (February 2013) DOI: /j.jvs Copyright © 2013 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Postoperative computed tomography (CT) scan after deployment of the Zenith Dissection Endovascular System (ZDES) showing misalignment of the bare stent. A, Misalignment of the proximal bare stent (one case). B, Misalignment of the distal bare stent (four cases).

3 Fig 2 The Zenith Dissection Endovascular System (ZDES) released on various diameter plastic models. This figure demonstrates how the circumferential suture (*) may protrude into the aortic lumen if deployed in small-diameter vessels.

4 Fig 3 This pictures illustrates the distal (or proximal) end of the Zenith Dissection Endovascular System (ZDES). A, The steel Cook-Z stent segments are sewn together with a circumferential suture (*) with a peak-to-valley configuration in the old design. The new design involves the last two stents of both the proximal and distal end. B, A new suture has been added between each peak of the Cook-Z stent segments (**) of the first and second stent of the proximal and distal end to configure them in a peak-to-peak design.
