CTICasesSaphenous Vein Graft Pseudoaneurysm
Imaging findings
Chest CT in an elderly patient with severe coronary artery disease demonstrates a large, partially thrombosed aneurysmal dilation of a saphenous vein aortocoronary bypass graft (SVG), arising from the proximal aortotomy site in the ascending aorta.
Key takeaways
Saphenous vein graft (SVG) aneurysms or pseudoaneurysms are rare, late complications of coronary artery bypass graft (CABG) surgery, usually presenting years post-procedure. They commonly arise from the proximal anastomosis at the aorta. Because they carry a high risk of rupture, compression of cardiac structures, or distal embolization, surgical or endovascular intervention is typically required.
