The effect of manufacturer's instructions for use compliance on Cook ZBIS iliac-branched endograft long term outcomes

Current guidelines indicate iliac branched endografts as the ideal means to preserve pelvic perfusion during endovascular aortic repair. Since patient vascular anatomy represents the main limitation to extensive use of these devices, off-label application may be considered to expand the number of patients being treated. Aim of this study is to evaluate long-term outcomes obtained using the Cook ZBIS endograft in the treatment of aorto-iliac aneurysms according to or outside manufacturer's instruction for use.
