Registry data on EndoAnchors for proximal endograft failure after EVAR

A multicenter registry study (2017-2025) analyzed 325 patients treated with the Heli-FX EndoAnchor system, either as prevention during primary EVAR (72%) or as treatment for type Ia endoleak/migration after prior EVAR (28%). The study reported higher technical and procedural success, and better freedom from proximal endograft failure at 5 years, in the prevention group versus the treatment group; short neck length (<7 mm), endoanchor use as treatment rather than prevention, use without a proximal aortic extension, and persistent type Ia endoleak on completion angiography were associated with higher failure risk. The authors state that future comparative studies are needed to clarify the clinical efficacy of this approach.

Most relevant for: Patients undergoing EVAR with a hostile or short proximal aortic neck, and those being evaluated for type Ia endoleak or endograft migration after prior EVAR.
