Abstract： 目的分析慢性阻塞性肺气肿上呼吸道的变化.方法对40例确诊为慢性阻塞性肺气肿患者和同期39例正常对照者行肺部螺旋CT扫描.测量以下指标并进行统计学分析:(1)气管横截面积(Ta);(2)气管指数(Ti),即气管的最大横径(Tc)和最大矢径(Ts)的比率;(3)左、右主支气管直径(分别记为Bl和Br);(4)左、右主支气管的分叉角度(Ba);(5)胸廓指数(Thi);(6)气体潴留指数(Ati).结果除Ba外,气肿组与对照组上述指标的均值差异都有显著性意义,气肿组的Ti与Ati呈明显的负相关(r=-0.593,P<0.001),Ti与Thi呈明显的正相关(r=0.537,P<0.01).Ta与Ati(r=0.105, P>0.05)和Ta与Ti(r=-0.125, P>0.05)均无明显的相关关系.结论 Ti减小是慢性阻塞性肺气肿气管的主要变化,而且这种改变与肺气体潴留和胸廓改变相关.
