Abstract
Pulmonary artery aneurysm (PAA) may be associated with congenital shunt disease such as patent ductus arteriosus, and its frequency and management are often controversial. We report successful surgical treatment of PAA following an operation for atrial septal defect (ASD). The patient was a 47-year-old woman who underwent closure of ASD at the age of 9. When she was investigated because of thyroid tumor, enlargement of her main pulmonary artery was pointed out and she was admitted to our hospital. Several examinations revealed a diagnosis of pulmonary valve insufficiency and 70mm PAA with dilatation extending to both proximal arteries. We performed replacements of pulmonary valve and pulmonary artery with a bioprosthetic valve and T-shaped graft. The patient is doing well 2 years after operation.
