摘要
目的:为给舌叶支气管及上、下舌段支气管的CT显示提供解剖学基础.材料和方法:观察了30例成人尸体左肺支气管树,其中13例进行了CT对照.主要结果:上、下舌段支气管的起始部居左肺纵轴中点下方、分别在上叶支气管、前段支气管和上段支气管下缘的下方16.3±4.2 mm、18.9±3.5mm和10.7±3.4mm;舌叶支气管及上、下舌段支气管内径分别3.3±0.4mm、2.9±0.5mm和3.0±0.4mmz,其与肺纵轴的夹角分别为26.0°±1.8°、49.6±11.7°和24.4°±3.0°.结论:结果可为支气管病变CF的诊断提供解剖学依据.
To provide the applied antomic basis for CT demonstration of lingular lobar bronchus, superior and inferior lingular bronchus, the bronchial trees of 30 adult left lungs(13 of them for CT images contrast) were observed and measured. The starting part of superior and inferior lingular bronchus startedfrom the inferior of the middle part of the longitudinal axis of the left lung. The distance from the inferior of the lower margin of the left superior lobar bronchus, anterior and superior segmental bronchus was 16.3±4.2 mm, 18.9+3.5 mm and 10.7±3.4 mm respectively. The internal diameter of the lingular lobar bronchus, superior and inferior lingular bronchus was 3.3±0.4 mm, 2.9±0.5 mm and 3.0±0.4 mm respectively, and the angle between the longitudinal axis of the left lung was 26.0°±1.8°,49.6°±11.7°and 24.4°±3.0°respectively. The results may provide anatomic data for the orientation of the slices of CT demonstration in bronchus and the diagnosis of bronchial abnormalities.
