The Anaconda stent-graft appears both safe and effective in terms of midterm clinical outcome and compares favorably with previously reported EVAR results. The ability to reposition the stent-graft is a particular advantage.

ADF is a rare but dangerous complication of EVAR. The sequela may be primarily attributed to graft infection, as seen in this series. However, the exact pathogenesis of the pathology remains largely unknown. Prompt diagnosis and intervention are crucial to avoid a fatal outcome.

The fixation of eight different endografts was increased by a mean of 30 N with four Aptus EndoStaples and by a mean of 57 N with six EndoStaples in this model. Endostaples can increase endograft fixation to levels equivalent or superior to that of a hand-sewn anastomosis. The application of six EndoStaples results in aortic tissue failure above the fixation zone, demonstrating fixation strength that exceeds inherent aortic integrity in these cadavers.
