Osteochondromas: An Unusual Cause of Vascular Disease in Young Patients: 2 Clinical Cases.

Osteochondroma is the most common benign tumor of bones in young patients. It is an unusual cause of nonatherosclerotic peripheral arteriopathy. It is mostly detected in youth and, thus, diagnosis can be delayed since symptoms such as claudication can be confused with muscular cramps. In case of clinical suspicion of peripheral artery disease in the young, the presence of an exostosis should be suspected. We reported our experience of 2 young patients with limb ischemia due to ab extrinseco compression of popliteal artery. In both cases, surgical exeresis of a lower limb exostosis was performed. In the first case, bypass surgery was not required since arterial wall was not damaged. In the second case, an autologous inverted saphenous vein femoro popliteal bypass was performed.
