Treatment of Asymptomatic Popliteal Artery Aneurysm ≥20 mm in Patients with Life Expectancy ≥5 Years
Clinical Scenario
This protocol addresses patients with an asymptomatic popliteal artery aneurysm (PAA) ≥20 mm in diameter and a life expectancy of ≥5 years. Despite the absence of symptoms, aneurysms at this size threshold carry a recognised risk of thromboembolic complications and limb loss, warranting elective intervention.
Approach
Open surgical repair is the recommended strategy for eligible patients in this scenario, using a bypass technique. The choice of conduit is central to the procedure — the full protocol defines the assessment criteria and specifies what alternatives apply when the preferred option is unavailable.

- We recommend that patients with an asymptomatic PAA ≥20 mm in diameter should undergo repair to reduce the risk of thromboembolic complications and limb loss.
- For asymptomatic patients, with a life expectancy of ≥5 years, we suggest open PAA repair, provided that an adequate saphenous vein is present.
- An adequate GSV has been extrapolated from PAD studies to be a GSV >3 mm in diameter and free of intraluminal stenoses or synechiae.
- In the absence of an adequate single-segment GSV, an alternative conduit such as an expanded polytetrafluoroethylene graft can be used with acceptable outcomes.
