Deep Vein Thrombosis in a Patient with Polycythemia Vera Who Underwent Hip Surgery: A Case Report.

A 68-year-old woman who suffered from polycythemia vera presented at our clinic with the chief complaints of pain, swelling, and a warm sensation in her left thigh. She had undergone a left bipolar hemiarthroplasty following a hip fracture 24 days prior to this presentation. Her erythrocyte sedimentation rate and C-reactive protein (CRP) levels were elevated. In addition, a postoperative infection was suspected in the 3-phase bone scan; therefore, she received intravenous antibiotic therapy. This approach proved to be ineffective and she was subsequently diagnosed with a deep vein thrombosis via color Doppler ultrasonography. It is interesting to note that a deep vein thrombosis can present with symptoms similar to those of a postoperative infection. Furthermore, an elevated CRP level is frequently observed in patients suffering from polycythemia vera. Therefore, the two conditions, which require completely different treatments, can be confused. We report on this case with a review of the relevant literature.
