The aim of this study was to analyse the influence of various preoperative risk factors on postoperative mortality after elective surgery for abdominal aortic aneurysms. It is a retrospective study of 263 consecutive operations performed in January 1994-December 1995 with a mean follow-up of 28.9 months (range 0-44). The case series consisted of 244 elective surgery patients and the prognostic parameters considered were: sex, age, concomitant vascular conditions and common atherosclerotic risk factors (diabetes, smoking, high blood pressure, dyslipidaemia) as well as concomitant ischaemic cardiopathy, chronic obstructive, bronchopneumopathy (COBP) or chronic kidney failure and allocation to one of the 4 ASA classes. Univariate and multivariate regression analyses was used to identify significant factors in immediate mortality and the Kaplan-Meyer method was applied to survival tables in order to assess long-term results. Peroperative mortality came to 1.2%/3 cases; 3-year survival to 86.2%. Among patients over 75 the survival figure fell to 76% or 77.4% in patients with heart disease. The study found that mortality after APIA surgery was low and 3-year survival satisfactory, while the factors with most impact on outcome were age and heart disease.
