You can address sac regression with Endurant™ II/IIs Stent Graft System
Why sac regression?
- Sac regression is defined by the SVS as the reduction in maximum diameter of the aneurysm sac by ≥ 5 mm.1
- Latest clinical signals suggest aneurysm sac regression is associated with better long-term outcomes.2
Addressing sac regression factors with Endurant
Endurant stent graft has demonstrated low type I and type II endoleaks in broad patient anatomies, with3,4:
- Accurate placement and controlled deployment*
- Continuous seal, fixation, and graft conformability*
- Durable hemostatic barrier and resistance against type II endoleaks5
Sac regression features and benefits video - (02:25)
Endurant II/IIs is designed to provide continuous seal in a dynamic environment†
Methodology:
Radial force and micro-CT scans were tested by an independent lab to model Endurant's performance in the proximal seal zone through the cardiac cycle.
Results:
M-stent maintains even distribution of contact pressure, resulting in optimal conformability in a pulsatile environment.

EVAR success
Aneurysm sac regression is a key indicator2 for EVAR success.
Dr. Ross Milner, Professor of Surgery, Co-director, Center for Aortic Diseases at the University of Chicago, discusses his thoughts on aneurysm sac regression post-EVAR.

"If you have sac shrinkage in the first year, the need for secondary interventions and therefore the need for intensive follow-up is different than those that don’t shrink."
–Prof. Hence Verhagen, M.D., Ph.D.

Clinical evidence VQI data
Latest data suggests aneurysm sac regression is associated with better long-term outcomes.2
Cohort that demonstrated sac regression at 1 year had significantly better outcomes than stable and expanding sac cohorts.
Freedom from all-cause mortality
Endurant data sac regression associated with better long-term outcomes
ENGAGE OUS Registry confirms sac regression link to better long-term outcomes. Patients with regressing sacs at 1 year had statistically significant better freedom from (FF) all-cause mortality (ACM) and FF secondary endovascular reinterventions than patients with stable or expanding sacs.6
In addition, ENGAGE OUS Registry 10-year data is available with longest-term follow-up of any global EVAR registry.7
Freedom from all-cause mortality
Freedom from secondary endovascular reinterventions
Endurant data consistent high sac regression rates
Endurant demonstrates consistent and high sac regression rates across straightforward and complex anatomies. New data suggests that patients with sac regression at 1 year appear to continue to have sac regression at 5 years.*
1-year sac regression is indicative of 5-year sac dynamics
Of those with sac regression at 1 year:
- 86% of patients with images at 5 years continue to have sac regression
- 2% have sac increase at 5 years
5Y sac regression rates§
