title: Endovascular Repair of Abdominal Aortic Aneurysms with the Anaconda™ Stent Graft: Mid-term Results from a Single Center.
abstract: BACKGROUND
  We aimed to report our experience with the Anaconda™ stent graft (Vascutek, Terumo, Inchinnan, Scotland, UK) for the endovascular treatment of abdominal aortic aneurysms (AAAs).
  
  
  METHODS
  The vascular unit database was interrogated to identify all AAA patients who underwent endovascular repair with the Anaconda™ device between March 2007 and June 2014. The peri-operative, short-term, and mid-term outcome was recorded focusing on complications and re-interventions.
  
  
  RESULTS
  Sixty-eight patients had been treated during the study period. Seven of these were symptomatic, one presented with an inflammatory aneurysm, and five presented with a ruptured AAA. The primary and the assisted primary technical success were 86.7 and 97.1%, respectively. There was no 30-day mortality in the elective or symptomatic group, but two of the ruptured AAA patients died. During a mean follow-up of 29 months (range 1-87), 14 patients died, none from aneurysm-related causes. A total of 11 endoleaks (17.5%) were detected in 10 patients during follow-up (1 type Ia, 4 type Ib, 6 type II), 4 of which required re-intervention (all for type Ib endoleak). Two iliac limbs occluded during the follow-up. The estimated overall survival, endoleak-free survival and re-intervention-free survival probability were 88.2, 78.4, and 83.4% at 1 year; 85.9, 73.8, and 78.9% at 2 years; and 80.6, 71.3, and 70.5% at 3 years, respectively.
  
  
  CONCLUSIONS
  Based on this series, the Anaconda™ stent graft appears to be safe and effective for the endovascular treatment of AAAs. Both the short-term and the mid-term results are satisfactory.
