Abdominal aortic aneurysms are a common cause of death among older adults in North America. Most commonly they are asymptomatic until they rupture. Rupture of an abdominal aortic aneurysm is usually lethal, so effective treatment to prevent rupture depends on accurate diagnosis on physical exam or one of various imaging modalities such as ultrasound, CT scan, or magnetic resonance imaging. Once the diagnosis is made, choice of treatment will depend on several factors including patient age and comorbidity, and aneurysm diameter. If elective treatment is contemplated there are currently two main options available to most patients: open surgical repair and endovascular repair. The fundamental differences between these two treatment options are outlined in this review.
Key words: abdominal aortic aneurysm, open surgical repair, endovascular aneurysm repair, older adults, aortic rupture.
