This study states that The objective of this study was to evaluate long-term results of self-expanding vs balloon-expandable hypogastric stent grafts in conjunction with iliac branch devices (IBDs) for aortoiliac aneurysm repair in a multicenter experience (pErformance of iLiac branch deVIces for aneurysmS involving the iliac bifurcation [pELVIS] Registry). All patients electively treated for aortoiliac aneurysm with the Cook IBD (Cook Medical, Bloomington, Ind) in nine European centers were reviewed. Clinical and imaging data were prospectively collected in each center, and a multicenter database was created and interrogated. The primary outcome was the primary patency of the IBDs. For the purpose of this investigation, three subgroups were identified: patients receiving a hypogastric balloon-expandable stent graft (BESg); those with a self-expanding stent graft (SESg); and those with any stent graft plus relining with a bare-metal stent (RESg). Between 2005 and 2017, there were 691 patients who underwent 747 elective endovascular repairs of aortoiliac aneurysms (n = 518 [75.0%]) or isolated iliac aneurysms (n = 173 [25.0%]) with Cook IBDs (n = 56 bilateral) in nine European centers. perioperative deaths, 3 (0.4%) technical failures, 7 (1.0%) graft thromboses, 30 (4.3%) reinterventions, and 1 (0.1%) conversion to open repair.
