title: Ruptured abdominal aortic aneurysms: factors affecting the early postoperative outcome.
abstract: BACKGROUND
  In spite of the progress in diagnosis and treatment of ruptured abdominal aortic aneurysms (RAAA) the mortality rate still remains very high (varying from 15% to 50% according to various experiences). This study is aimed at analyzing the relative contribution of preoperative hemodynamic conditions and of operative and postoperative factors to outcome of patients operated on for ruptured abdominal aortic aneurysms.
  
  
  METHODS
  For this purpose a retrospective case series involving 152 patients operated on in emergency for RAAA, during the period 1990-1994, has been reviewed. In this group we examined the site of rupture, the size of the aneurysms, the presence or not of a shock condition at admission, the existence of inflammatory aspects, the adopted type of prosthesis.
  
  
  RESULTS
  The mortality rate was 24.3% (37 patients). In 10 patients (27%) the cause of death was an irreversible hemorrhagic shock. Eight patients (21.6%) died for an intestinal infarction. In 7 patients the fatal outcome was due to the development of an acute renal failure. Five patients (13.5%) underwent an acute myocardial infarction and other five a multiorgan failure. Two patients (5.5%) eventually died for respiratory insufficiency.
  
  
  CONCLUSIONS
  The results of our study seem to confirm that the outcome of patients affected by rupture of abdominal aortic aneurysms depends not only on the preoperative hemodynamic condition but also on the expertise of the surgical team.
