title: Percutaneous closure of a coronary artery-to-vein graft anastomotic pseudoaneurysm presenting as acute coronary syndrome after recent coronary artery bypass grafting.
abstract: Pseudoaneurysm formation has been reported in degenerated coronary artery saphenous vein bypass grafts, as well as in native coronary arteries after interventional procedures or blunt trauma. In contrast, pseudoaneurysm formation arising from the anastomotic site of native coronary vessels soon after coronary artery bypass grafting is rare, and neither the clinical presentation of this phenomenon nor its treatment is well described. We present the case of a 63-year-old man, a recent coronary artery bypass grafting patient, who presented with acute coronary syndrome due to a large and expanding pseudoaneurysm of the saphenous vein-to-ramus intermedius artery graft anastomosis. After several attempts, we successfully treated the pseudoaneurysm by means of percutaneous coil embolization. To our knowledge, this is the first report of acute coronary syndrome secondary to a pseudoaneurysm at the coronary artery-saphenous vein graft anastomosis. In addition, this appears to be the first report of the percutaneous treatment of such a pseudoaneurysm by means of coil embolization.
