[Non-atherosclerotic lower limbs ischemia in young athletes].

Although rare, the iliac endofibrosis and the popliteal artery entrapment syndrome are undoubtfully recognised as causes of intermittent claudication in young patients, particularly in athletes. The authors report the clinical case of a young female athlete, with disabling claudication of the right lower limb due to a stenosis of the external iliac artery and a case of an acute ischemia in a male cyclist owing to an extrinsic compression of the popliteal artery by anomalous muscular bundles. Both cases underwent successful surgical management. The early suspicion and diagnosis of these situations is of utmost importance to prevent complications that may be particularly severe.
