Percutaneous closure of giant saphenous vein graft aneurysm

BACKGROUND: Aneurysmal dilatation of saphenous vein grafts used for coronary artery bypass grafting is a rare complication. These aneurysms are often large in calibre and pose a risk of rupture with significant haemorrhage. CASE SUMMARY: We describe a case whereby a large saphenous vein graft aneurysm is closed percutaneously using a vascular plug to cease flow and promote thrombosis of the aneurysm whilst reconstructing the occluded native artery to negate ischaemia. CONCLUSION: Saphenous vein graft aneurysms following coronary artery bypass graft are rare and late complications. The preferred modality of closure is via percutaneous approach that requires meticulous planning to achieve a good outcome.
