FRANCO, Sergio et al. Aneurysms and pseudo aneurysms from coronary venous grafts. Rev. Col. Cardiol. [online]. 2005, vol.11, n.8, pp.401-404. ISSN 0120-5633.

Aorto-coronary aneurysms/pseudo aneurysms from saphenous vein grafts are an unusual complication of myocardial revascularization surgery. We report the case of a 61 years old male patient who had suffered an inferior wall myocardial infarction 14 years before. Coronary angiography showed severe two-vessel disease. Anastomosis of the left internal mammary artery to the mid third left anterior descendant artery and saphenous vein grafting to the distal third of the right coronary artery, were performed. In March 2003 he complains of anginous pain. Chest X ray showed a right paracardiac mass. Coronary arteriography revealed an aneurysm of the venous bypass graft to the right coronary artery. During the evolution, the patient presents massive hemoptysis, requiring emergency surgery. A fistulous communication from the aneurysm in the venous coronary bypass to the middle right pulmonary lobule was found. This article reviews etiology, clinical findings, diagnostic methodology and actual treatment of this entity. Up to this publication’s date approximately 60 cases have been reported in the English literature.
