Abstract: | PURPOSE: To identify perioperative variables which may influence mortality of elective abdominal aneurysm repair (AAA). METHOD: 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). CONCLUSION: 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. |
