Patient-Friendly Summary of the ACR Appropriateness Criteria: Abdominal Aortic Aneurysm Follow-up (Without Repair)

The aorta is a main blood vessel in the chest and abdomen. An abdominal aortic aneurysm (AAA) is an abnormal enlargement of the aorta in the abdomen; it is often asymptomatic, meaning that it causes no symptoms. Monitoring the size and growth of the aneurysm is important because it is often fatal if the aneurysm ruptures. This is more likely in individuals with AAA that grows more than 2 mm per year. Treatment should be considered when an individual without symptoms has an AAA larger than 5.4 cm in men and 4.9 cm in women.
