title: [Chronic pulmonary thromboembolism originating from left forearm deep vein thrombosis: a case report].
abstract: Upper extremity deep venous thromboembolism has become increasingly common due to the use of subclavian venous access. However, forearm deep venous thrombosis is rare. We report a case of chronic pulmonary thromboembolism originating from left forearm deep venous thrombosis. A 66-year-old woman was admitted to our hospital because of dyspnea, which had worsened over the previous 2 months. Echocardiography showed severe right ventricular enlargement and pulmonary hypertension. Perfusion lung scintigraphy revealed multisegmental perfusion defects. No likely factors responsible for hypercoagulability were found. The patient had a history of left radial fracture and had been treated with external fixation. Venography of the upper and lower extremities revealed total occlusion of the deep veins of the left forearm with collateral vessels, but no evidence of other upper or lower extremity venous thrombosis.
