title: Popliteal artery pseudoaneurysm secondary to osteochondroma in children and adolescents: a case report and literature review.
abstract: Osteochondroma is the most frequent bone tumor and can rarely cause vascular complications. False aneurysms of the popliteal artery due to an osteochondroma are not common in the pediatric population. The case of an 11-year-old boy who presented with a painful mass on the posterior aspect of his distal thigh is described. Radiologic studies revealed an osteochondroma of the distal femur and a pseudoaneurysm of the popliteal fossa. A combined orthopaedic and vascular surgery was undertaken. The exostosis was excised and the popliteal artery was repaired by performing a venous patch angioplasty technique. A review of the literature regarding this vascular complication in young patients is also reported.
