A small abdominal aortic aneurysm is defined as a diameter less than how many centimeters?

Aneurysm size guides when to monitor versus intervene. While any AAA is larger than normal when it exceeds about 3 cm, the practical management threshold for deciding repair is around 5.5 cm. Aneurysms smaller than this are typically watched with regular imaging and risk‑factor control, because rupture risk remains lower. Once the diameter reaches 5.5 cm or more, the risk of rupture increases enough that elective repair is usually considered. So a small abdominal aortic aneurysm is defined as less than 5.5 cm.
