    Abstract:
    Aneurysm of the main pulmonary artery is a rare anomaly with a poorly understood pathogenesis. We report the successful surgical resection and repair of a pulmonary artery aneurysm using aneurysmectomy and replacement of the pulmonary artery with Dacron, a procedure with excellent longterm outcome that eliminates the risk of recurrence. The 65-year-old male patient presented with a marked decrease in exercise tolerance and worsening dyspnea. He had a history of pulmonary stenosis diagnosed during childhood, episodic shortness of breath beginning during his teenage years, hypertension, and smoking. On physical examination, the patient appeared generally well. Computed tomographic scan of the chest revealed an 8-cm aneurysm involving the main pulmonary artery and pulmonary artery bifurcation. Coronary angiography showed a massive aneurysm of the main and left pulmonary arteries, with mild dilation of the proximal right pulmonary artery. Surgery was performed through a median sternotomy with the use of normothermic, bicaval cardiopulmonary bypass. The aneurysm of the main pulmonary artery and dilated bifurcation of the pulmonary artery was excised and reconstruction was performed using a 22-mm Dacron graft. The patient's postoperative course was uneventful. He was discharged to home on postoperative day 5 and was well at 1-month follow-up.
