Material and Methods: A retrospective study conducted on a prospectively collected database between 2010 and 2012. Factors considered as potentially influencing outcomes were: iliac axes’ diameters and tortuosity and presence of TASC II C/D femoro-popliteal disease. Outcome measures were reintervention and mortality rates at follow-up. Conclusion: Our experience suggests that diameters of access vessels and the presence of PAD could affect the outcome of EVAR. t SD P R-Torurtuosity 0.38 0.10 .70 L -Tortuosity 0.30 0.99 .76 R-CIA Diameter 0.22 0.61 .83 L -CIA Diameter 0.23 0.46 .81 R-EIA Diameter 1.91 0.16 .05 L -EIA Diameter 0.77 0.16 .44
