title: Percutaneous occlusion of a pulmonary aneurysm causing hemoptysis in a patient with pulmonary atresia and aortopulmonary collaterals.
abstract: A 28-year-old male was referred for cardiac catheterization because of recurrent severe hemoptysis necessitating resuscitation and subsequently preventing weaning from ventilation. He had a history of pulmonary atresia, ventricular septal defect, overriding aorta with right-sided aortic arch diagnosed at birth. Eisenmenger's syndrome ensued and he was not felt to be suitable for corrective cardiac surgery. He had multiple major aortopulmonary collateral vessels to both lungs with a large aneurysm in an artery to the right lower lobe, which was suspected to be the source of his bleeding. Occlusion of this aneurysm was achieved percutaneously using an Amplatzer septal occluder device. He had no further bleeding and was successfully weaned from ventilation. Six months later, he has recovered to his functional baseline and has not had any further episodes of hemoptysis.
