Treating at-risk EVAR patients

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.

ESAR mimics a sutured anastomosis to provide durability through reinforcement of the proximal seal in EVAR.1–3

Key factors for suboptimal outcomes

Hostile necks

  • 4.5 times increased risk of Type la endoleak (P = 0.01)

  • 10 times increased risk of aneurysm-related mortality (P = 0.01) 

(n = 1,559 follow-up at one year)4

Wide necks†

  • 6.7 times more likely to have Type la endoleak (P = 0.001)

  • 10 times more likely to have sac expansion (P = 0.009)

  • 5.1 times more likely to rupture (P = 0.01)

(n = 6,602 follow-up ranged from 2.7 years [mean] to 3.9 years)5

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 outcomes1-5, 9-15

ESAR reinforces and protects the proximal seal leading to better outcomes in wide necks.1, 3, 5, 9, 13-15

ANCHOR registry wide neck cohort three-year data (n = 72)9

  • 98.5% three-year freedom from (FF) type la endoleak (one 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

  • 93.4% (28/30)‡ sacs regressing/stable at three years

  • 66.7% (20/30)‡ sac regression at  three years
