Neck angulation was < 45 degrees in all patients but one who had an angulation of 69 degrees. The neck length was > 1.5 cm in all patients except one who had a neck length of 1.3 cm. Seven patients had Endoanchors placed as part of a Phase II trial of the Aptus Endovascular Abdominal Aortic Aneurysm (AAA) Repair System (Aptus Endosystems, Inc.), which included an investigational infrarenal aortic stent graft routinely fixed to the neck with Endoanchors. There were between 4 and 10 Endoanchors used in each patient. Data regarding the anatomy of the aneurysm and the seal zones was collected as well as data regarding outcomes with regards to endoleak, migration, and decrease in the size of the aneurysm sac.Īverage age was 73 years (range 62-81), and all but 3 patients were male. Inclusion criteria were any patient who had Endoanchors placed in either an infrarenal endovascular aneurysm repair (EVAR) or thoracic endovascular aneurysm repair (TEVAR). The purpose of this study is to report experience with an endovascular aortic anchor device used to provide seal and fixation of stent grafts for endovascular aneurysm repair.Ī retrospective chart review was carried out on 14 patients who had Heli-F X™ Aortic Endoanchors (Aptus Endosystems, Inc., Sunnyvale, CA) placed.
