Abstract

ObjetiveA long-term survñval study in operated and non-operated patients with infrarenal abdominal aortic aneurysms, and an assessment of mortality causes. Material and methodsTwo hundred and twenty patients (209 men and 11 women) with infrarenal aortic aneurysms treated in our hospital from 1992 to 1997 were retrospectively studied. There were 62.4% asymptomatic, 12.4% symptomatic, and 25.2% ruptured aneurysms. One hundred and sixty-one patients (49 xvith ruptured aneurysms) were operated on, with an operative mortality of 7.2% in non-ruptured and 61.2% in ruptured aneurysms. Twentynine patients were not operated on because of their risk. Survival probability was compared between patients surviving after surgical procedures and patients that were not operated on because of their risk, and mortality causes were analyzed in both groups. Long-term survival was compared in patients surgically treated for non-ruptured AAA and ruptured AAA, excluding perioperative deaths. Finally, influence of some risk factors on long-term mortality in electively operated patients was assessed. ResultsCumulative survival probability at 1,3 and 5 years in surgically-treated patients was 83%, 70%, and 70%, Whereas in non-surgically-treated patients because of risk was 69%, 26%, and 13% (p<0.0001). No survival difference was found in patients surviving after surgical procedures for ruptured and non-ruptures AAA. Main mortality cause was cancer in the whole group. ConclusionsLong-term survival in patients surviving after surgical procedures is the same for ruptured and non-ruptured AAA, and it is significantly higher than in non-operated patients. No significant influence was observed for risk factors on long-term mortality.
