Surgical Treatment of a Giant Coronary Artery Aneurysm: A Modified Approach

A common surgery for giant coronary artery aneurysms includes aneurysmal ligation and coronary artery bypass grafting. We report a patient with such an aneurysm involving the left main trunk in whom the aneurysmal characteristics precluded this approach. Surgical strategy was modified and the aneurysmal sac was dissected open to define the coronary vasculature before ligating the aneurysm and completing the bypass operation.
