Large saphenous venous graft aneurysm with right atrial fistulous communication: Case report and review of literature

Abstract

We report a case of a 56-year-old Caucasian man who presented with acute onset of substernal chest pain at rest with electrocardiogram showing diffuse ST segment depression. He had coronary artery bypass graft surgery 16 years ago with a left internal mammary artery graft to the left anterior descending artery and saphenous vein grafts to the right coronary artery (RCA) and left circumflex artery. He underwent coronary angiography, which showed two large aneurysms in the saphenous venous graft (SVG) to the RCA and a venous leak from the aneurysm. The venous leak was later confirmed with computer tomographic scan to be a fistulous communication between the SVG and the right atrium. We discuss in detail about the treatment options of SVG aneurysm.
