What is the screening timing indicated for AAA with diameter 3.0-3.9 cm?

Explanation:
The main idea is that surveillance intervals for an abdominal aortic aneurysm depend on its size, since smaller aneurysms grow slowly and can be safely monitored with periodic imaging. For an aneurysm measuring 3.0 to 3.9 cm, the recommended follow-up imaging is every 12 months. This annual cadence reflects the typical slow growth rate and aims to detect any progression toward the repair threshold (about 5.5 cm or faster growth) without subjecting the patient to unnecessary testing. More frequent imaging isn’t needed for this size unless there’s evidence of rapid growth or other risk factors, and waiting longer than a year could miss meaningful changes.
