Recommendations for the Threshold for AAA Repair

Referenced studies that support the recommendations are summarized in the Online Data Supplement.

COR LOE RECOMMENDATIONS
1 A 1. In patients with unruptured AAA, repair is recommended in those with a maximal aneurysm diameter of ≥5.5 cm in men or ≥5.0 cm in women.16
1 B-NR 2. In patients with unruptured AAA who have symptoms that are attributable to the aneurysm, repair is recommended to reduce the risk of rupture.7,8
2b C-LD 3. In patients with unruptured saccular AAA, intervention to reduce the risk of rupture may be reasonable.9
2b C-LD 4. In patients with unruptured AAA and aneurysm growth of ≥0.5 cm in 6 months, repair to reduce the risk of rupture may be reasonable.15
