title: [A case of pulmonary arteriovenous fistulas (PAVF) treated with detachable balloon embolotherapy].
abstract: A case of pulmonary arteriovenous fistulas (PAVF) treated with detachable balloon embolotherapy is reported. A 31-year-old man was admitted to hospital because of polycythemia and hypoxemia. He had a history of dyspnea on exertion and transient cerebral ischemic attacks (TIA). Chest roentgenogram revealed a peripheral lobulated lesion in the right upper lung field and a coin lesion in the left lung field connected by dilated blood vessels to each hilus. Pulmonary angiography and right heart catheterization was performed. Four PAVFs were observed in bilateral lung field, and the intrapulmonary shunt ratio was 25.8%. Because the patient was symptomatic, we embolized each PAVF with a detachable balloon without complications. After embolotherapy, there was improvement in his symptoms. hypoxemia and shunt ratio. Recent reviews have highlighted the need to consider embolotherapy for bilateral multiple PAVF. We conclude that embolotherapy with detachable balloon is a very useful procedure for treatment of bilateral multiple PAVF.
