    Abstract:
    Saphenous vein graft (SVG) aneurysm is one of the late unusual complications of coronary artery bypass grafting (CABG). We report a case of a very large SVG aneurysm successfully treated with a vascular plug 4. A 94-year-old man was referred to our hospital for an expanding aortic aneurysm. The patient had undergone CABG 24 years prior, with three SVGs to the left anterior descending (LAD) artery, left circumflex arteries (LCX) artery, and right coronary artery (RCA). A computed tomography scan of the chest demonstrated an 8.8 cm × 6.5 cm aneurysm arising from an ascending aortic wall. Coronary angiography revealed an aneurysm arising from the proximal segment of the SVG to the RCA. The distal graft anastomosis of the SVG to the RCA and LCX was occluded. Another SVG to the LAD was widely patent. From a radial approach, a 5-Fr catheter (Tempo, Cardinal Health, OH) was advanced into its cavity, and a 7-mm Amplatzer vascular plug 4 (AVP-IV, AGA Medical Corporation, MN) was successfully delivered. Contrast CT confirmed a thrombus development in the cavity. The patient was discharged home. However, interventions utilizing vascular plug insertion are limited to cases of graft occlusion. We report a case of the successful treatment of a large SVG aneurysm using the Amplatzer vascular plug 4.
