Abstract

SummaryThis is a case of a thrombo-occlusion occurring below an inferior vena cava (IVC) filter inserted in a patient with polycythemia vera and deep vein thrombosis. The patient was a 48-year-old man with polycythemia vera and a chief complaint of swelling, redness, and bursting pain in his right leg. After admission, contrast-enhanced computed tomography scanning demonstrated a pulmonary artery thrombus and deep vein thrombosis. We inserted a Gunther tulip vena cava filter on day 1 for the prevention of pulmonary embolism (PE), and started anticoagulation therapy based on the guideline of the Japanese Circulation Society for DVT. In addition to intravenous anticoagulants, we started therapeutic phlebotomy to improve the hypercoagulability state. On day 4, our patient complained of back pain caused by thrombo-occlusion below the IVC filter, despite the anticoagulation therapy and two therapeutic phlebotomies. From this case, we concluded it is important to lower hemoglobin level and hematocrit as early as possible for IVC-filter-insertion in patients with polycythemia vera.
