The patency rate of saphenous vein grafts (SVGs) for children with Kawasaki disease (KD) tends to decline during the early years after coronary artery bypass grafting (CABG). Although degenerative changes have been considered the main cause of SVG occlusion, there have been no reports on the histopathologic features of the SVG in patients with KD. We herein describe a redo off-pump total arterial revascularization in a 43-year-old man with KD, 34 years after the first CABG using SVG. The histopathologic examination of the longest-lived SVG demonstrated that graft occlusion was mainly caused by the diffuse intimal hyperplasia.
