Popliteal aery aneurysms account for 70% of peripheral aerial aneurysms. Popliteal aneurysms may embolize repetitively over time and occlude distal aeries. They are often undetected. The symptoms range from sudden onset pain and paralysis to sho distance claudication that slowly lessens as collateral circulation develops. Ref: Rapp J.H., Owens C.D., Johnson M.D. (2013).
