Background

Popliteal artery aneurysms are the most common peripheral arterial aneurysm and carry substantial risks of limb loss.

Methods

We conducted a retrospective cohort study at a tertiary care center to identify patients with popliteal artery aneurysms from 2008 to 2022.

n = 330 popliteal artery aneurysms

Results

more than a third needed reintervention or amputation after repair

HR 1.63 (95% CI 1.11 to 2.41)

null 1

1.11

2.41

CI excludes the null - significant

More results

Open repair comprised 79% (250/330), most often a medial approach (75%, 187/250) with autologous vein conduit (65%, 162/250).

Open-repair patients were younger than endovascular patients (69 vs 74 years; P = .006) with similar cardiovascular profiles.

More results

Patency outcomes were similar between groups, with 6-month primary patency of 83.4% after open repair and 84.1% after endovascular repair (P = .44).

Conclusion

Major adverse limb event risk was comparable across operative strategies and aneurysm morphologies, suggesting that aneurysm size and thrombus burden alone should not preclude consideration of either open repair or endovascular repair.
