摘　　要：目的应用多层64排螺旋CT观察左肺上叶支气管分支的CT影像,并分析左肺上叶支气管分支的解剖学特征。方法回顾性分析2019年1月⁃2020年12月在我院接受多层64排螺旋CT扫描的体检人员240例,将其分为男性组和女性组,其中男性120例,女性120例。对比两组受检者左肺上叶支气管解剖结构差异。此外进行亚组分析,受检者在性别分组前提下根据年龄分组(分为青年组、中年组、老年组)分析同性别中的年龄差异带来的支气管形态差异,以此对左肺上叶支气管分支形态进行解剖学分析。结果男性的左肺上叶支气管分支的管径大小相比于女性而言较大,但是分支的开口角度明显小于女性,两组数据差异有统计学意义(P<0.05)。从亚组分析中可以得出,无论是男性还是女性,老年组的支气管管径大小和分支开口角度都明显大于青年组和中年组受检者,差异有统计学意义(P<0.05)。青年组和中年组之间的支气管管径大小各分支开口角度之间的差异不明显,两组差异无统计学意义(P>0.05)。结论成年人支气管结构受到性别和年龄的影响,男性支气管管径大于女性,而开口角度小于女性,老年人的支气管管径和开口角度要高于年轻人,中年人和青年人之间的支气管管径大小和开口角度大小之间无明显差异。Objective Multi slice 64 slice spiral CT was used to observe the CT images of the bronchial branches of the upper lobe of the left lung,and to analyze the anatomical characteristics of the bronchial branches of the upper lobe of the left lung.Methods 240 physical examination personnel who underwent multi⁃slice 64 slice spiral CT scanning in our hospital from January 2019 to December 2020 were retrospectively analyzed.They were di⁃vided into male group and female group,including 120 males and 120 females.The anatomical differences of left up⁃per lobe bronchus between the two groups were compared.In addition,subgroup analysis was conducted.On the premise of gender grouping,the subjects were divided into youth group,middle⁃aged group,elderly group and gen⁃der group according to age.The bronchial morphological differences caused by age differences in the same sex were analyzed,so as to analyze the morphology of bronchial branches in the upper lobe of the left lung.Results The di⁃ameter of the left upper lobe bronchial branch in men is larger than that in women,but the opening angle of the branch is significantly smaller than that in women.The difference between the two groups is statistically significant(P<0.05).From the subgroup analysis,it can be concluded that whether male or female,the bronchial diameter and branch opening angle in the elderly group are significantly larger than those in the young group and the middle⁃aged group,and the difference is statistically significant(P<0.05).There was no significant difference in bronchial diameter and branch opening angle between young group and middle⁃aged group,and the difference between the two groups was not statistically significant(P>0.05).Conclusion The bronchial structure of adults is affected by gen⁃der and age.The bronchial diameter of men is larger than that of women,while the opening angle is smaller than that of women.The bronchial diameter and opening angle of the elderly are higher than that of the young.There is no sig⁃nificant differ
