Endovascular stent graft treatment of a pulmonary artery pseudoaneurysm

A 5-year-old girl with pulmonary atresia, ventricular septal defect, hypopl astic pulmonary arteries, and multiple pulmonary artery reconstructive proc edures presented with an enlarging pulmonary artery pseudoaneurysm. A previ ous attempt to occlude the aneurysm was unsuccessful and the aneurysm conti nued to enlarge. We describe the percutaneous placement of an endovascular stent graft to occlude the aneurysm. This novel use of a covered graft effe ctively treated a potentially lethal problem without reoperative thoracotom y or sternotomy. (C) 2001 by The Society of Thoracic Surgeons.
