Percutaneous Occlusion of Acquired Aorto-Coronary Venous Fistula After Coronary Artery Bypass Graft Surgery: Initial Experience Using the Self-Expandable Nitinol Vascular Plug

Inadequate anastomosis of aorto-coronary grafts to the coronary venous system represents an infrequent but potentially serious complication of coronary artery bypass surgery. Different surgical techniques and percutaneous devices have been described for the permanent correction of these fistulas. We report two cases of iatrogenic aorto-coronary fistulas successfully treated with percutaneous occlusion using the self-expandable nitinol device (vascular plug).
