title: Bilateral pleural effusion and pulmonary edema caused by a fistulous aneurysm of the ductus arteriosus.
abstract: We report an unusual case of pulmonary edema and rapid collection of bilateral pleural effusion caused by a fistulous large aneurysm of the ductus arteriosus (DAA). The diagnosis was performed by contrast CT and aortography. The cause of pulmonary edema and effusion was thought to be both elevated capillary pressure due to overload of the pulmonary circulation and decreased water clearance due to compression of the lymphatic system by the large DAA itself. Therefore, fistulous DAA should be considered when a continuous heart murmur and swelling in the aortic window are recognized. Once DAA is diagnosed, surgery should be performed without delay.
