Acute dissection of ascending aortic aneurysm in a patient with previous coronary artery bypass grafting.

Six years after coronary artery bypass grafting, a 61-year-old man underwent emergency surgery for annulo-aortic ectasia and acute dissection. The aneurysmal tissue and aortic valve were excised and reconstruction was achieved with a composite graft. The patent vein grafts were attached to the composite graft and the original coronary orifices were closed.
