Improved effectiveness of the repositionable GORE EXCLUDER AAA endoprosthesis featuring the C3 delivery system compared with the original GORE EXCLUDER AAA endoprosthesis for within the instructions for use treatment of aortoiliac aneurysms

摘要

Objective: To compare two endograft types, the original GORE EXCLUDER AAA endoprosthesis (W. L. Gore & Associates, Flagstaff, Ariz) with the repositionable GORE EXCLUDER featuring the C3 delivery system, which allows repositioning of the proximal part of the graft to achieve accurate placement in relation to the renal arteries, in unselected patients with aortoiliac aneurysms. In a second nested, substudy we investigated the relative effect of the standard Gore and Gore Dryseal introducer sheaths on intraoperative transfusion needs.
