Diagnosis and management of asymptomatic abdominal aortic aneurysm

AAA: abdominal aortic aneurysm; CT: computed tomography.
* Typically identified by abdominal ultrasound obtained to evaluate palpable abdominal mass, for screening purposes, or follow-up evaluation of another identified aneurysm (eg, thoracic aortic aneurysm, popliteal artery aneurysm). AAA has also been identified incidentally on plain abdominal radiography, spine imaging studies, and others.
¶ Per the Society for Vascular Surgery (SVS) guidelines^[1]. We often prefer to obtain ultrasound annually in conjunction with ongoing vascular evaluation.
