Risk Of Rupture

Abdominal Aortic Aneurysms (AAAs) are localized enlargements of the aorta. If untreated, AAAs will grow irreversibly until rupture occurs. Ruptured AAAs are usually fatal and are a leading cause of death in the United States, killing 15,000 per year (National Center for Health Statistics, 2001). Surgery to repair AAAs also carries mortality risks, so surgeons desire a reliable tool to evaluate the risk of rupture versus the risk of surgery.

Abdominal aortic aneurysms (AAAs) are characterized by dilation of the abdominal aorta at least 1.5 times the normal diameter of the average adult, which is approximately 2 cm in men and 1.5 cm in women. Although the incidence is relatively low, this disease can be devastating, with AAAs accounting for roughly 15,000 deaths annually in the United States. This review covers the focused history and physical examination of a patient with a known AAA, evaluation of small and large AAAs, and surveillance of AAAs. Tables highlight recommendations for best medical management of small AAAs during the surveillance period, and information on nicotine replacement and nonnicotinic pharmacotherapy. Figures show a calcific rim consistent with the atherosclerotic rim of an AAA, a small AAA, a small inflammatory AAA, and age-adjusted effects of lifestyle characteristics and risk of AAA. An algorithm provides an approach to nonoperative management of stable AAAs. This review contains 5 figures, 3 tables, and 86 references.

Abdominal Aortic

The local dilation of the infrarenal aorta, termed an abdominal aortic aneurysm (AAA), occurs over several years and may eventually lead to rupture, an event currently ranked the 15th leading cause of death in the United States [1, 2]. AAA can often remain quiescent and asymptomatic, making the diagnosis and treatment of AAA patients a clinical challenge. For patients whose AAAs dilate to a critical diameter there are two standard treatments: open surgical resection and endovascular repair (EVAR). EVAR involves inserting an endovascular graft into the aneurysm to prevent pressurization of the AAA cavity.

Significant Disease

Abdominal aortic aneurysms (AAAs) represent a significant disease in the western world as rupture of AAA is currently the 15th leading cause of death in the United States [1,2]. The rate of incidence of this disease is also thought to be increasing given the aging population. While AAA rupture is attributed to the gradual weakening of the wall, the mechanisms of aneurysm initiation, growth, and development remain relatively unclear. The role of biomechanics in the diagnosis and prevention of AAA rupture has been reported [3].

Natural Progression

Abdominal Aortic Aneurysms (AAAs) — the localized enlargement of the abdominal aorta — represent the 13th leading cause of death in the United States. The natural progression of small (3–5 cm) AAAs is 2–6% growth per year until rupture or surgical repair [1]. As AAAs enlarge, adverse hemodynamic conditions (including regions of low mean wall shear stress and high particle residence time) are exacerbated under normal resting conditions.
