True aneurysms of the femoral and popliteal arteries are the most common peripheral arterial aneurysms. An alteration in the balance between production and degradation of vascular wall constituents, resulting from the culmination of immunological, inflammatory, mechanical, and genetic factors, leads to aneurysm formation. Popliteal artery aneurysms will lead to symptoms in 60–70% of patients and limb loss can occur in up to half of the symptomatic patients if not treated. Femoral artery aneurysms are believed to have a similar natural history, which may also lead to limb loss. Physical exam and/or ultrasound screening of select at-risk patients must be performed early for the best treatment outcomes. Timely intervention in the form of open surgical bypass is the gold standard treatment with universally-accepted long-term results. For popliteal and select femoral aneurysms, endovascular treatment has emerged with feasible mid-term results and may be an alternate option in selected patients.
