    中国煤炭工业医学杂志000210 早在 70 年代,Carpentier 等人[1]曾使用桡动脉(RA)作为冠脉搭桥手术的移植物,但是不久很快被摒弃,因为术后32%的桡动脉出现闭塞,另外 32%显示严重的广泛狭窄[2,3]。最近重新应用 RA 是由于发现 Carpentier 手术中被认为闭塞的 RA 重新开放,血管造影显示大约 15 年无动脉粥样硬化损害[3]。我们的研究是选取冠脉搭桥手术中所遗的桡动脉和乳内动脉(ITA)片段,光镜下观察 RA 和 ITA 动脉粥样硬化的发生率和程度。

    1 材料和方法

    1.1 材料 取我院 1997 年 9 月~1998 年 12 月冠脉搭桥手术患者 43 例,男 41 例,女 2 例,平均年龄(61.3±6.99)岁。外检标本常规福尔马林固定,石蜡包埋,连续切片厚 5μm,HE染色观察。……
