Scanning electron microscope study of two vein grafts which were removed after 50 months of implantation as aorta-coronary artery vein grafts showed considerable subendothelial thickening, which consisted of relatively cell-poor fibrous layer. In one of the grafts the endothelial surface was intact; the second graft showed focal loss of endothelial cells. Sections of two fresh human veins, studied prior to their insertion as aorta-coronary artery vein grafts, have shown that they retained an intact endothelial layer. A third fresh vein, however, showed focal damage with missing endothelial cells and adherent fibrin.
对作为主动脉 - 冠状动脉静脉移植物植入50个月后取出的两根静脉移植物进行扫描电子显微镜研究，结果显示有相当程度的内皮下增厚，其由细胞相对较少的纤维层组成。其中一根移植物的内皮表面完整；第二根移植物显示内皮细胞有局灶性缺失。两根新鲜人体静脉在作为主动脉 - 冠状动脉静脉移植物插入之前进行研究的切片显示，它们保留了完整的内皮层。然而，第三根新鲜静脉显示有局灶性损伤，内皮细胞缺失且有纤维蛋白附着。
