Mortality Rates following Endovascular Repair of Abdominal Aortic Aneurysms

Purpose:To present the perioperative and late mortality following endovascular repair (EVR) of abdominal aortic aneurysms (AAAs).Methods:Data were collected prospectively on 221 patients undergoing AAA EVR over a 4-year period (median 5-month follow-up). Patients were classified preoperatively as high risk with at least 1 of these features: serum creatinine > 150 μmol/L, ischemic heart disease or poor left ventricular function, respiratory function 80 years.Results:One hundred forty (63.3%) patients were classified as high risk, the most common criterion being cardiac disease (n = 96, 68.6%). There were 25 (11.3%) deaths in the 30-day perioperative period, 22 (15.7%) in the high-risk group compared to 3 (3.7%) in the acceptable-risk group (p = 0.02). The most common causes of perioperative death were multisystem organ failure and myocardial infarction. A further 21 (9.5%) late deaths occurred, 16 (...
