Fistula between a saphenous vein graft aneurysm and the pulmonary artery trunk

We report the case of a 52-year-old man who was admitted for atypical thoracic pain 18 years after a saphenous vein bypass graft of the left anterior descending coronary artery. Investigations demonstrated an aneurysm of the middle portion of the vein graft with a fistulous communication to the pulmonary artery trunk. The aneurysm was excised surgically, and the fistula was closed with an autogenous pericardial patch.
