Peroperative factors influencing the outcome of elective abdominal aorta aneurysm repair.
OBJECTIVE
To identify perioperative variables which may influence mortality of elective abdominal aneurysm repair (AAA).


METHODS
prospective study of patients undergoing elective AAA repair between 1986 and 1997.


RESULTS
Four hundred and seventy patients (438 men, 32 females) with a mean age of 69.4+/-13 years and aneurysms with a diameter of 60+/-3 mm were operated on with a 1-month mortality rate of 5.3%. Multivariate analysis identified the following independent risk factors for mortality: age >70 (p<0.0001), a past history of myocardial infarction (p<0.0001), preoperative renal insufficiency (p<0.0001), reoperation (p<0.0001), colonic necrosis (p<0.0001), and severe postoperative medical complications (p<0.0001).


CONCLUSIONS
Intra- and postoperative events affect the outcome of AAA repair, independently of preoperative factors, and should be described when presenting the results of AAA repair.
