Cycling related common femoral artery disease: an unusual case in an otherwise healthy male.

A cyclist reported gradual onset, bilateral leg claudication without any atherosclerotic risk factors and with a normal vascular examination. Duplex ultrasound and magnetic resonance angiography revealed bilateral focal stenoses due to coralline plaques of the common femoral arteries (CFAs) but normal proximal and distal vasculature. A surgical endarterectomy with vein patch angioplasty resolved all symptoms. Cyclist's iliac syndrome (whereby mechanical and anatomical factors in competitive cyclists and runners lead to arterial kinking and subsequent intimal hyperplasia, endofibrosis and, ultimately, stenoses of the external iliac arteries) is well documented. This is the first report to our knowledge of a similar process isolated to the CFA.
