Percutaneous treatment of a massive saphenous vein graft aneurysm.

Saphenous vein graft (SVG) aneurysms are a rare, frequently late presenting, potentially fatal complication of coronary artery bypass graft (CABG) surgery. They are often discovered incidentally during radiological tasks such as chest x-ray or CT but can present clinically with symptoms such as worsening angina and breathlessness as well as complications such as rupture or myocardial infarction. Given the risks if left untreated, consideration should be given to treatment either through percutaneous routes or open surgery. However, because of a lack of strong evidence, there are no definitive guidelines on the treatment of SVG aneurysms. We describe a patient with an extensive cardiac surgical history who presented with angina and breathlessness and was found to have a large SVG aneurysm, subsequently successfully treated with percutaneous coronary intervention with covered stents.
