Popliteal artery pseudoaneurysm caused by an osteochondroma--a traditional medicine massage sequelae

We report an unusual case of a popliteal aneurysm complicating a distal femoral osteochondroma caused by the repeated massages of a traditional medicine practitioner (sinseh). Management was by excision of the exostosis and reconstruction of the damaged arterial segment by a reversed long saphenous vein graft. We advice against massage over an osteochondroma on the distal medial aspect of the femur and suggest prophylactic removal of such lesions because of this potential complication.
