EndoSuture Aneurysm Repair (ESAR)
Today, EVAR is an effective and efficient treatment for abdominal aortic aneurysm.
However, there are certain endovascular aneurysm repair (EVAR) patients who are at greater risk for neck dilatation and/or loss of proximal seal, leading to worse outcomes.
Retrospective analysis of 552 elective EVARs5
Meta-analysis6 of neck diameters ≥ 25, ≥ 28, and ≥ 30 mm
Short
Wide
Angulated
Conical
AAA is a progressive dilating disease even after EVAR or open surgical repair.7
22% of EVAR patients were lost to imaging follow-up at 1 year.8 Independent risk factors for not following up:
Neck diameter is an independent risk factor for neck dilatation.10 Diameters ≥ 25 mm have greater risk of dilatation after EVAR
(p = 0.02).11
Wide necks are more likely to develop Type Ia endoleaks (p = 0.049),12 which transmit the highest pressures into the sac.13
Learn how ESAR with the Heli-FX EndoAnchor system reinforces the proximal seal and protects against neck dilatation to minimize both transient and persistent Type Ia endoleaks.
Learn about the benefits of ESAR and the key elements of deployment.
Learn from the experts about the clinical utility of ESAR as a solution for wide neck patients.
ESAR with the Heli-FX EndoAnchor system is your defense for patients at risk for suboptimal outcomes.
