摘要 目的 :了解肺气肿患者的升主动脉根部变化 ,及其与主动脉扩张的危险因素的关系。方法 :利用二维超声技术研究了 5 8例严重肺气肿患者 ,测量其升主动脉的瓣环、瓦氏窦、窦与升主动脉连接处及升主动脉的近端的直径。测量结果与年龄、性别相匹配的无肺气肿及正常人员的正常值进行比较 ,并分析升主动脉根部和心源性危险因素 (高血压、高胆固醇血症及糖尿病 )的关系。结果 :显示肺气肿患者升主动脉根部内径测量值显著大于正常对照组 (P<0 .0 0 0 1)以及无肺气肿患者组 (P<0 .0 5~ 0 .0 0 0 1) ,肺气肿患者的瓦氏窦扩张发生百分率 4 3% ,升主动脉扩张发生百分率 5 9%。多因素线性回归分析表明肺气肿是升主动脉根部扩张四个测量点的主要决定因素。高血压与升主动脉瓦氏窦、窦与升主动脉连接处、近端升主动脉的进一步扩张有关。结论 :肺气肿患者升主动脉根部显著扩张大于无肺气肿患者 ,高血压与近端升主动脉 。
