Abdominal aortic aneurysms. A comparative analysis of surgical treatment of symptomatic and asymptomatic patients.
This retrospective study of 120 patients identified three separate variables that influence operative mortality in patients with abdominal aortic aneurysms. These are age, presence or absence of symptoms, and presence of three preoperative risk factors or more. Based on this study and the fact that any aneurysm may rupture without warning, we conclude that observation of good risk asymptomatic patients until symptoms occur is unjustified. Asymptomatic patients less than seventy years old can undergo abdominal aortic aneurysmectomy with minimal mortality. Carefully selected asymptomatic patients more than seventy years old can also under surgical intervention with acceptable results.
