Endovascular stent graft treatment of a pulmonary artery pseudoaneurysm

A 5-year-old girl with pulmonary atresia, ventricular septal defect, hypoplastic pulmonary arteries, and multiple pulmonary artery reconstructive procedures presented with an enlarging pulmonary artery pseudoaneurysm. A previous attempt to occlude the aneurysm was unsuccessful and the aneurysm continued to enlarge. We describe the percutaneous placement of an endovascular stent graft to occlude the aneurysm. This novel use of a covered graft effectively treated a potentially lethal problem without reoperative thoracotomy or sternotomy.
