Deep vein thrombosis associated with femur osteochondroma: report of a case.

The predisposing condition of deep vein thrombosis (DVT) is venous stasis or hypercoagulable state. Impaired venous blood flow caused by extrinsic compression is relatively rare situation. Only 3 cases of deep vein thrombosis due to osteochondroma have previously been reported in English literature. We report a case of a 21-year-old man, who presented with left lower leg pain and swelling due to extrinsic compression of femoral vein by an osteochondroma. In the case of vascular complications due to an osteochondroma, prompt surgical intervention should be made to avoid irreversible vein wall damages.
