Endurant AAA Stent Graft System(Medtronic) two year results

Medtronic Inc.has announced the two-year results from its U.S. clinical study of the Endurant AAA Stent Graft System for Abdominal Aortic Anuerysm. Presented at this year's Charing Cross International Symposium in London, the prospective Endurant U.S. investigational device exemption (IDE) study's complete results at two years continue to demonstrate durable clinical performance with strong safety and efficacy in long-term follow-up. These results add to a growing body of evidence on the Endurant AAA Stent Graft, which continues to deliver consistent clinical results in both controlled trials and real-world registries.The Endurant U.S. IDE study enrolled 150 AAA patients at 26 U.S. medical centers. Significant to clinical practice, the study included patients with "landing zones," or healthy aortic neck lengths, as short as 10 mm, whereas most other trials of aortic stent grafts have required neck lengths of at least 15 mm. The study also monitored changes in aneurysm size and stent graft migration, a concern with current endovascular treatment, as well as the occurrence and type of endoleaks. The study found that nearly all (97.6 percent) of the aneurysm sacs that were treated with the Endurant AAA Stent Graft decreased or remained stable in size at two years post-procedure, with only 0.8 percent Type I endoleaks and no Type III endoleaks.
