对150例冠状动脉搭桥术患者的隐静脉进行了组织学检查。经常观察到形态学变化，主要包括内膜和内侧纵肌层的纤维化。内膜纤维化很少严重到足以使管腔显著狭窄。统计分析表明，内膜和内侧纵肌层的纤维化不随年龄的增长而增加。可以考虑在接受冠状动脉搭桥手术的患者中使用冷冻的隐静脉组织切片，以丢弃不合适的移植物并指导外科医生使用替代管道。
A histological examination was carried out on the saphenous veins used in 150 consecutive patients undergoing aortocoronary bypass. Morphological changes were observed frequently and consisted mainly of fibrosis of the intima and of the medial longitudinal muscular layer. Intimal fibrosis was rarely severe enough to narrow the lumen significantly. Statistical analysis disclosed that the fibrosis of the intima and of the medial longitudinal muscular layer do not increase with age. The use of frozen histological sections of the saphenous vein in patients undergoing aortocoronary bypass operations could be considered in order to discard unsuitable grafts and to direct the surgeon to alternative conduits.
