title: Endovascular treatment for acute aortic syndrome.
abstract: BACKGROUND
  The term "acute aortic syndrome" (AAS) includes conditions of high mortality, such as ruptured aneurysm, pseudoaneurysm and, aortic dissection. Open surgery for these cases has demonstrated unsatisfactory results, and endovascular treatment has become an excellent alternative.
  
  
  METHODS
  We performed a retrospective review of patients with AAS who underwent endovascular treatment in our emergency department from July 2009 to February 2011. They represent 64% (16 of 25) of all patients with AAS seen during this period.
  
  
  RESULTS
  Sixteen patients underwent endovascular treatment: eight ruptured aneurysms, six aortic dissections, one nonruptured painful aneurysm, and one pseudoaneurysm. No intramural hematoma or penetrating atherosclerotic ulcer was found. The mean age was 64.3 years, and arterial hypertension (100%) and smoking (64.7%) were the major comorbidities. Technical success rate was 93%, and overall 30-day mortality was 6.25%.
  
  
  CONCLUSIONS
  Endovascular treatment for AAS was feasible. Technical success, 30-day mortality, hospital stay, and procedure time were similar to those of the other series reported in the literature, and the endovascular approach has became the main technique for AAS in our hospital.
