title: Endovascular aortic aneurysm repair with the Endurant stent-graft: early and 1-year results from a European multicenter experience.
abstract: OBJECTIVE
  To assess preliminary results of the Endurant stent-graft, which was developed to treat patients with abdominal aortic aneurysms (AAAs) and challenging aortoiliac anatomy.
  
  
  METHODS
  From November 2007 to October 2008, 45 patients with AAAs were treated with the Endurant stent-graft in three European vascular centers. Thirty-eight of the 45 patients (84%) had a hostile anatomy of the proximal neck. Early (30 days), early midterm (6 months), and late midterm (1 year) results were analyzed in terms of technical success, clinical success, morbidity, and mortality.
  
  
  RESULTS
  Intraoperative immediate technical and clinical success was achieved in all cases. At completion angiography, a type II endoleak was detected in seven of the 45 patients (16%) and an iliac limb stenosis was diagnosed and successfully treated in five (11%). At discharge, computed tomography demonstrated a type I endoleak in one of the 45 patients (2.2%). At 30 days, a graft limb thrombosis was diagnosed (2.2%) and successfully treated. The 30-day overall technical and clinical success rates were 97.8% (44/45 cases) and 95.6% (43/45 cases), respectively. During follow-up (mean duration, 8 months; range, 5-16 months), the type I endoleak was successfully treated with an aortic extension. Estimated freedom from type I or III endoleak and repeat intervention at 1 year was 97.8% (44/45 cases) and 93.3% (42/45 cases), respectively.
  
  
  CONCLUSIONS
  The initial experience shows that the Endurant stent-graft appears to be effective in endovascular repair of AAAs in patients with hostile aortoiliac anatomy. This graft permits a broader group of patients to be treated with endovascular aneurysm repair; however, further studies are needed to evaluate the long-term results.
