Figure 5From: Influence of ischemia before vein grafting on early hyperplasia of the graft and the dynamic changes of the intima after grafting Scanning electron micrographs of the intima surface of grafted veins (original magnification ×400) after 1 h and 1, 2, 3, 7, 14, or 28 days. A: vein grafts with 15-min ischemia; B: vein grafts with 90-min ischemia.Back to article page
