Pain in your foot or behind your knee? Swelling in your leg? Ulcers on your feet that don't heal? These could be signs of a popliteal aneurysm. A popliteal aneurysm can burst. That can cause life-threatening, uncontrolled bleeding. The aneurysm may also cause a blood clot, which might lead to a leg amputation.
A popliteal aneurysm is a bulge and weakness in the wall of the popliteal artery, which sends blood to your knee joint, thigh, and calf.
