title: [Acute aortic dissections. Hospital outcome of 186 cases].
abstract: OBJECTIVE
  To determine in hospital outcome acute aortic dissection patients.
  
  
  METHODS
  We revised 186 consecutive cases (up to 14 days of dissection), in a period of 6 years. The patients were divided according to Daily's classification (types A and B).
  
  
  RESULTS
  Type A--127 cases: a) 75 were surgically treated (37 died); b) 2 were medically treated (both died); c) 39 died before the definitive treatment could be initiated; d) 11 died misdiagnosed or undiagnosed. The total mortality was 70.0%. Type B--59 cases: a) 11 complicated cases were surgically treated (6 died); b) 40 were medically treated (8 died); c) 7 died before the definitive treatment could be initiated; d) one died misdiagnosed. The total mortality was 37.25%. In summary, 41.4% of the patients survived. 28.4% died despite the definitive treatment, 24.7% died before the definitive treatment could be initiated and 6.4% died without the correct diagnosis.
  
  
  CONCLUSIONS
  The acute aortic dissection is a dramatic situation, mainly type A. In this type of dissection many patients (41%) died misdiagnosed, undiagnosed or without enough time to surgical therapy. So, an earlier diagnosis and treatment are imperative.
