Late survival after abdominal aortic aneurysm repair.
OBJECTIVE
This study was undertaken to determine the late survival of patients operated successfully for abdominal aortic aneurysm (AAA) repair, to compare survival data with that of the age- and sex-matched general population, to identify the causes of late death, and to determine the factors influencing late survival.


METHODS
A total of 187 consecutive patients underwent elective surgical AAA repair between January 1987 and December 1991. There were 11 postoperative deaths (early mortality rate 5.9%). The remaining 176 patients formed the basis of this cohort-based retrospective study. Six patients (3.4%) were lost to follow-up. Mean follow-up was 71 months.


RESULTS
A total of 70 patients (39.8%) died during the study period. Coronary artery disease (CAD) and cancer were the two main causes. The survival rate at five years (71.6%) was lower than that of the sex- and age-matched general population (90.6%). Neither arterial hypertension nor CAD had any influence on late survival. In contrast, age and chronic renal failure were predictive variables of late survival.


CONCLUSIONS
The life expectancy of patients who undergo successful AAA repair is not as good as that of the age- and sex-matched general population. Late survival depends on the patients' age at the time of surgery and the existence of preoperative chronic renal failure.
