    Abstract:
    The patient was a 34-year-old man, who was referred to our hospital because of abnormal shadows in the right lower lung field on a chest radiograph during a medical screening. Chest computed tomography (CT) showed a pulmonary arteriovenous fistula 23 x 17 mm in size in the anterior basal segment of the right lung, together with a single artery and single vein. He had no symptoms and did not have Osler-Weber-Rendu syndrome. Coil embolization was performed in order to decrease the risk of complications associated with right-to-left shunting. Transcatheter embolization using interlocking detachable coils and detachable fibered coils was successfully performed without severe complications. Then, 320-row multidetector CT revealed that the blood flow from the pulmonary artery disappeared just after coil embolization, the blood flow from the pulmonary vein flowed backward, and the fistula was contrasted. The fistula had almost completely disappeared 8 months after embolization. We confirmed that blood flows were interrupted by 320-row CT and pulmonary angiography. 320-row CT was useful for the evaluation of pulmonary arteriovenous fistula and coil embolization.
