title: Rationale of EndoAnchors in abdominal aortic aneurysms with short or angulated necks.
abstract: Diseased pararenal aortic anatomy including thrombus, calcification, and progressive dilatation, may impact the long-term durability of endovascular aortic aneurysm repair. EndoAnchors have been shown to mimic the security of a hand sewn aortic anastomosis. Several investigators have evaluated the use of EndoAnchors to repair endograft problems or repair type 1 endoleaks in the abdominal or the thoracic position. The ANCHOR Registry is designed to evaluate up to 2000 patients at multiple sites in North America and Europe who have been treated with the Aptus Heli-FX EndoAnchor System to secure an aortic endograft. The registry collects important clinical characteristics of patients (1000) who are treated at the initial endograft implant (PRIMARY ARM) due to the presence of an endoleak or the concern about late failure due to a hostile aortic neck. An additional 1000 patients, who undergo a secondary procedure for treatment of an endoleak or other proximal graft failure (e.g., migration, aortic dilatation) will also be evaluated and followed (REVISION ARM). Currently, more than 290 patients have been entered and will be followed to evaluate the long-term efficacy of this treatment.
