Pseudoaneurysm developed after aortic root homograft implantation.
A 55-year-old man with severe infective endocarditis underwent aortic root replacement using a homograft concomitant with saphenous vein grafting to the left anterior descending artery. The patient developed angina due to stenosis of the proximal anastomosis of the vein graft accompanied by a 2-cm pseudoaneurysm. This complex lesion was successfully managed with urgent coronary artery bypass surgery through a left thoracotomy, followed by a redo replacement of the old aortic homograft. The mechanism and the basis of the treatment strategy adopted for this case are described.
