Aortic endovascular repair | Cardiovascular
EndoSuture aneurysm repair (ESAR)
ESAR mimics a sutured anastomosis to provide durability through reinforcement of the proximal seal in endovascular aneurysm repair (EVAR).1–3
Patients at risk
Today, EVAR is an effective and efficient treatment for abdominal aortic aneurysm (AAA). However, there are certain EVAR patients who are at greater risk for neck dilatation and/or loss of proximal seal, leading to worse outcomes.
Key factors for suboptimal outcomes
Hostile necks
- 4.5X increased risk of Type la endoleak (P = 0.01)
- 10X increased risk of aneurysm-related mortality (P = 0.01)
(n = 1,559 follow-up at one year)4
Wide necks*
- 6.7X more likely to have Type la endoleak (P = 0.001)
- 10X more likely to have sac expansion (P = 0.009)
- 5.1X more likely to rupture (P = 0.01)
(n = 6,602 follow-up ranged from 2.7 years [mean] to 3.9 years)5

Additional considerations for abdominal aortic aneurysm (AAA)
Long life expectancy
AAA is a progressive dilating disease even after EVAR or open surgical repair.6
Follow-up challenges
22% of EVAR patients were lost to imaging follow-up at one year.7 Independent risk factors for not following up:
- Urgent or emergent cases7
- Multiple comorbidities7
- Older patients7
- Travel time to hospital8
ESAR: Reinforced seal, redefined outcomes
ESAR reinforces and protects the proximal seal leading to better outcomes in wide necks.
ANCHOR registry wide neck cohort three-year data (n = 72)9
- 98.5% three-year freedom from (FF) type la endoleak (1 patient presented with a type la at their 30-day follow-up, self-resolved)
- 100% three-year FF secondary procedures to treat Type la
- 100% three-year FF migration
- 100% three-year FF rupture
- 91.3% (21/23)† sacs regressing/stable at three-year
- 60.9% (14/23)† sac regression at three-year
