Successful resection of ductus arteriosus aneurysm in infancy.

We report a case of thrombosed patent ductus arteriosus aneurysm in an infant. The aneurysm was detected accidentally on chest roentgenogram and presented as globular soft tissue density mass in left posterosuperior mediastinum. Resection of the aneurysm was performed without cardiopulmonary bypass. Two years after operation the patient is well and growing normally.
