title: [Evolution of endovascular treatment compared with medical and surgical treatment in patients with aortic syndrome type B].
abstract: BACKGROUND
  Surgical treatment is accepted as conventional treatment of patients with acute aortic syndrome associated to ischemic complications. Promising results of thoracic endovascular aortic repair (TEVAR) has expanded its indication to a variety of thoracic aorta pathologies.
  
  
  OBJECTIVE
  The objective of this study was to evaluate the safety and efficacy of TEVAR during the in-hospital period and at mid-term follow-up, and compare with medical and surgical treatment in patients who presented with acute aortic syndrome (AAS) type B.
  
  
  METHODS
  Of 113 patients that fulfilled the inclusion criteria, 58 underwent endovascular treatment (Group 1), 34 had medical treatment (Group 2), and 21 had surgical treatment (Group 3).
  
  
  RESULTS
  Global and cardiovascular in-hospital mortality was superior in Group 3 (p = 0.0001). Mean follow-up was 30.4 ± 12.2 months. The survival rate free from cardiovascular death was 92.5, 60.5, and 42.9, in Group 1, 2, and 3, respectively, at 36 months.
  
  
  CONCLUSIONS
  Our results suggest that endovascular treatment is feasible, safe, and associated with a reduction of in-hospital and mid-term major adverse cardiovascular events, and superior survival rate compared with surgical and medical treatment.
