What is the recommended management for a small abdominal aortic aneurysm?

For a small abdominal aortic aneurysm, the best approach is watchful waiting with regular imaging and proactive risk-factor management. When an aneurysm is small, the immediate risk of rupture is low, so repairing it right away isn’t typically beneficial. Instead, clinicians monitor size over time using ultrasound or CT, commonly re-imaging every 6–12 months to detect any growth. Key to this approach is risk-factor modification to slow progression and reduce rupture risk. This includes stopping smoking, controlling blood pressure, optimizing lipids (often with statins), and overall vascular risk reduction. Repair becomes recommended when the aneurysm reaches a threshold size (about 5.5 cm in most men, with slightly different guidance for women in some cases) or if there is rapid growth (e.g., increases more than about 0.5 cm in six months or more than 1 cm per year) or if symptoms develop. For a small, asymptomatic aneurysm, these circumstances aren’t met, so regular monitoring with risk-factor modification is the preferred plan.
