Combined internal mammary artery graft in coronary bypass: 18-year follow-up

Abstract

Graft preference is a key point for long-term patency in coronary artery bypass grafting. We present a patient with multivessel coronary artery disease who underwent coronary artery bypass grafting 18 years ago. Revascularization of the left coronary system was performed by using a combined internal mammary artery (IMA) graft, which consisted of an end-to-end anastomosis of left IMA (in situ) and right IMA (free), with the interposition of a small piece of vein. A coronary angiography at the 18-year follow-up revealed patency of all sequential anastomoses with an enlarged combined IMA graft.
