title: [Surgical treatment of chronic pulmonary thromboembolism caused by a cavernous hemangioma at the lower limb].
abstract: A 48-years old man complained of dyspnea and was admitted to the hospital. Chest enhanced CT confirmed the presence of the thrombus in the pulmonary artery. Cardiac catheterization showed severe pulmonary hypertension (mean PAP 75 mmHg). ATIII level, protein C and S antigen were within normal range. Anticardiolipin antibody and lupus anti-coagulant determination were negative. He was diagnosed as chronic pulmonary thromboembolism, and underwent pulmonary thromboendarterectomy via median sternotomy under deep hypothermic intermittent circulatory arrest. At the same time IVC filter was inserted. The origin of the thrombus was not detected before operation, but after surgery, MR angiography of total body showed a cavernous hemangioma at left lower limb. We speculated this lesion was the origin of pulmonary embolism.
