Long-term outcomes of the Endurant endograft in patients undergoing endovascular abdominal aortic aneurysm repair

Endurant Stent Graft for Treatment of Abdominal Aortic Aneurysm Inside and Outside of the Instructions for Use for the Proximal Neck: A 14-Year, Single-Center Experience

“…Group 2 also showed more in-hospital days and more perioperative complications (p = 0.01 and 0.041, respectively), although the complications were all access-related rather than proximal-neck-related. The influence of the adherence to the IFU on sac shrinkage has been investigated for the Endurant stent graft as well as other commercially available endografts, and as in our experience, no statistically significant difference has been reported on sac shrinkage or expansion rates [10,11]. Interestingly, although the small number of aorticrelated deaths makes it difficult to obtain a statistically significative difference, it appears that aneurysm-related mortality is not affected by the adherence to the IFU; it is worth considering, however, that the aneurysm-related mortality rate and the 30-days mortality rate of Group 2 is more than double that of Group 1.…”

“…All persistent high-flow endoleaks were treated, while for type 2 endoleaks with sac stability or reduction, a watchful waiting approach was employed. Reintervention for type 1A endoleaks consisted of proximal aortic extension with an aortic cuff (12), proximal extension with an endoanchor implant (11), suprarenal device implantation (6), and open surgery treatment in 6. Exclusion of type 1B endoleak was always performed successfully with an endovascular procedure of distal extension.…”
