The 3 most common reasons for not meeting inclusion criteria were not having 2 or more vein grafts to native vessels with at least 75% stenosis and comparable runoff, having a concomitant non-CABG cardiac surgical procedure, and having documented or suspected untreated diffuse peripheral vascular disease. At 1 year, 203 patients were eligible for intravascular ultrasound (IVUS) imaging. Among the 203 saphenous vein grafts (SVGs) with external support, 143 SVGs had the intimal hyperplasia area assessed by IVUS; 55 SVGs were occluded/severely diseased, which precluded the IVUS procedure; and intimal hyperplasia area was not measurable in 5 SVGs for technical reasons. Among the 203 SVGs without external support, 142 SVGs had the intimal hyperplasia area assessed by IVUS; 56 SVGs were occluded/severely diseased, which precluded the IVUS procedure; and intimal hyperplasia area was not measurable in 5 SVGs for technical reasons. CABG indicates coronary artery bypass graft procedure.
