OBJECTIVES: EndoAnchors have been used to address proximal @entity2333 including type Ia endoleaks and endograft migration after endovascular @entity449 repair (EVAR). METHODS: The study population included 100 @entity1 with one-year follow-up in the ANCHOR study. A primary cohort (N   =   73) comprised @entity1 who underwent EndoAnchor implantation at the time of an initial EVAR and a Revision cohort (N   =   27) included @entity1 treated remote from EVAR. A hostile neck was defined for neck length <10   mm, neck diameter >28   mm, angulation >60  , conical configuration or significant mural @entity715 or @entity460 . RESULTS: Baseline anatomy included neck length of 17        14   mm, diameter of 27        5   mm, and angulation of 35        18  ; 83% of @entity1 had hostile necks. Over 18        4 months of clinical follow-up, six @entity1 (6%) underwent @entity439 -related reinterventions. There were no @entity1756 . Over 13        2 months of imaging follow-up, freedom from type Ia endoleak was 95% in the Primary Arm and 77% in the Revision Arm (P   =   .006). @entity439 sacs regressed   >   5   mm within one year in 45% of the Primary cases and in 25% of the Revisions. @entity439 expansion   >   5   mm occurred in one revision @entity1 . CONCLUSION: Despite a high frequency of hostile neck anatomy, proximal neck complications were relatively infrequent after EndoAnchor use.
