title: [Surgical results among 100 patients with type A aortic dissection: retrospective review].
abstract: BACKGROUND
  Tipe A aortic dissection involves the ascending aorta and has high mortality rates without surgical treatment.
  
  
  OBJECTIVE
  To report the results of surgical treatment of type A aortic dissection.
  
  
  METHODS
  Retrospective review of medical records of 100 patients aged 17 to 78 years (73% males) operated between January 2000 and August 2008, for type A aortic dissection. Follow up was performed with telephone interviews and review of national death records.
  
  
  RESULTS
  Eighty three percent of patients had an acute dissection. Operative mortality was 27 and 20% for patients with acute and chronic dissection, respectively. Mortality was 50% among patients aged 70 years or more, compared with 21% among their younger counterparts, The most common complication was bleeding that required a new surgical procedure in 18% of patients. Actuarial survival was 70% at five years. Cardiovascular problems caused the death of two of the nine patients that died during follow up.
  
  
  CONCLUSIONS
  Surgical mortality among patients with type A aortic dissection was higher among patients with acute episodes and those aged 70 years or more.
