title: The Bolton Treovance endograft: single center experience.
abstract: OBJECTIVE
  In the last two decades, results of endovascular aortic repair (EVAR) for the treatment of infrarenal abdominal aortic aneurysms (AAAs) have significantly improved thanks to the evolution of stent-grafts and endovascular delivery systems. However, further development is still needed to reduce the incidence of complications and secondary reinterventions. We present our initial experience with the Treovance abdominal aortic stent-graft (Bolton Medical, Barcelona, Spain), a new-generation trimodular endovascular device, developed to increase flexibility, lower profile, improve deployment and sealing mechanisms.
  
  
  METHODS
  We treated 8 patients with anatomically suitable non-ruptured AAA.
  
  
  RESULTS
  Primary technical success was obtained in all patients, and no 30-day device-related complications nor deaths were reported. One patient experienced graft limb occlusion at 3 months, and underwent surgical conversion. At 1-year follow-up (completed in 6 patients), no device-related complications nor type I or III endoleak were observed.
  
  
  CONCLUSIONS
  Initial personal experience with the Treovance abdominal stent-graft was satisfactory with regard to technical success and short-term clinical results. This new-generation endovascular device performed well even in angulated or heavily calcified anatomies.
