Deep vein thrombosis in an adolescent.

We report an unusual case of deep vein thrombosis following minor trauma in an adolescent who presented with a swollen, tender, lower extremity. Work-up consisted of a venogram which demonstrated occlusion of the deep venous system in the proximal leg. The patient was hospitalized for intravenous heparin followed by oral anticoagulation therapy. The problem of deep venous thrombosis in adolescents and the approach to diagnosis are discussed.
