title: [Risk factors for mortality in abdominal aortic surgery].
abstract: OBJECTIVE
  To analyse pre and peroperative variables for predicting mortality after abdominal aortic surgery.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  We prospectively included 658 consecutive patients undergoing abdominal aortic surgery from January 1993 to July 1997.
  
  
  METHODS
  Age, gender, hypertension, history of myocardial infarction or coronary revascularization, angina pectoris, diabetes, arrhythmia, cardiac insufficiency, serum creatinine > 150 mumol.L-1, beta-blockers therapy, calcium channel inhibitors, angiotensin converting enzyme inhibitors were preoperative analysed variable. Type of aortic disease (anuerysms versus aortic occlusion), duration of surgery, blood loss, type of laparotomy (medium versus lombotomy) were peroperative analysed variables. Haemoglobinemia was monitored during surgery and patients were transfused if haemoglobinaemia < 80 g.L-1.
  
  
  RESULTS
  Thirty-three patients died after aortic surgery (5%). In multivariate analysis, angina pectoris (OR = 5.47, P < 0.001), chronic obstructive bronchopulmonary disease (OR = 2.27, P = 0.05) and duration of surgery (OR = 1.60, P < 0.001) were the independent predictive factors of mortality. Age, blood loss were predictive factors only in univariate analysis.
  
  
  CONCLUSIONS
  Angina pectoris and COBP were the two independent preoperative factors of mortality. The duration of surgery was the only peroperative factor. Well monitored blood loss was not a predictive factor.
