A case of giant saphenous vein graft aneurysm successfully treated with catheter intervention.

The patient was a 67-year-old man who had undergone coronary artery bypass graft surgery using a saphenous vein graft (SVG) 22 years before. Computed tomography angiogram revealed a large aneurysm of the SVG (38 × 42 mm in diameter; 80-mm long) and total occlusion of the left anterior descending artery (LAD). We first performed percutaneous coronary intervention for chronic total occlusion of the native LAD with bi-directional approach via the SVG. One month later, we performed the trans-catheter embolization of the SVG and occluded the SVG using multiple coils. This case demonstrates that trans-catheter embolization after recanalization of native coronary artery is an effective strategy to treat an SVG aneurysm. © 2015 Wiley Periodicals, Inc.
