A. Diagnostic Evaluation for Abdominal Aortic Aneurysm
1. Palpable pulsatile abdominal mass.
2. Unexplained lower back pain or abdominal pain.
3. Known extremity aneurysmal disease.
4. Follow-up of a previously demonstrated abdominal aortic aneurysm.
5. Follow-up of patients with history of placement of an aortic or iliac endoluminal graft.
B. Screening Evaluation for Abdominal Aortic Aneurysm
1. Men 65 years or older.
2. Women 65 years or older with cardiovascular risk factors.
3. Family history of aortic and peripheral vascular aneurysmal disease. Groups that should be seriously considered for screening include patients with a history of smoking, look hypertension, look and a family history of an aortic aneurysm in a first-degree relative.
