摘要 冠状动脉粥样硬化性心脏病是严重威胁人类健康的最常见的后天性心脏病之一。随着人口老龄化和生活方式的改变,其发病率逐年增长,并呈年轻化趋势。经过几十年的发展,冠状动脉旁路移植术( coronary artery bypass grafting , CABG )现已成为治疗冠状动脉粥样硬化性心脏病,尤其是左主干和多支血管严重病变的重要外科手段,在美国每年有超过30万人接受CABG手术[1]。自体大隐静脉由于具有位置表浅,取材方便,有足够的长度可供使用等优点而被广泛使用。然而, CABG术后1年内有10%~15%的移植静脉发生闭塞,术后10年只有50%的静脉桥仍保持通畅[2-3]。研究表明,静脉桥血管病变是CABG术后不良预后的独立风险因子,其导致心肌梗死、再手术和死亡的概率可高达对照组的13倍[4-5]。因此,静脉桥血管病变是CABG术后疗效的主要制约因素之一。
