Bronchiectasis due to pulmonary artery aneurysm.

Pulmonary artery aneurysm (PAA) is a rare entity. We report what we believe to be the first case of bronchiectasis resulting from a PAA, which in turn developed after a previous Senning procedure for transposition of the great vessels during infancy. The patient had bronchiectasis secondary to compression of the left main bronchus because of a PAA. Bronchiectasis is a condition indicating lung resection. Despite the patient receiving medical therapy to treat recurrent pneumonia, lobectomy was necessary to prevent this and other possible complications.
