Nearly blocked femoral artery. Coloured angiogram (blood vessel X-ray) of the leg of a 67-year-old man with an ultra-tight stenosis (narrowing, lower centre) of part of the femoral artery in the lower part of his thigh. The artery has been highlighted using a contrast medium. The stenosis is of the superficial femoral artery at the femoro-popliteal junction. The condition required a treatment to widen the artery, known as endo-percutaneous angioplasty (EPA).
