目的:评价胸片支气管走行角度变化对判断左心房增大的价值。材料与方法:测量94例CR胸片心脏重度增大病例的气管隆突角及左主支气管(与体轴)夹角,分别计算气管隆突角与超声左心房前后径、左主支气管(与体轴)夹角与左心房前后径之间的相关系数并分析其相关关系。结果:气管隆突角与左心房前后径及左主支气管(与体轴)夹角与左心房前后径之间的相关系数分别为0.59和0.51。结论:胸片气管隆突角及左主支气管(与体轴)夹角的增大在一定程度上反映左心房增大。
OBJECTIVE: To evaluate the value of the change of walking angle of the chest radiograph in judging the enlargement of the left atrium. MATERIALS AND METHODS: The angle of tracheal carina and the angle between the left main bronchus and the axis of the trachea were measured in 94 patients with severe chest X-ray. The distances between the tracheal carina and the left atrium and the left main bronchus Body axis) angle and left atrial anterior and posterior diameter of the correlation coefficient between and analyze the correlation. Results: The correlation coefficients between the angle of tracheal carina and left anterior chamber, the angle between left main bronchus and body axis and the anteroposterior diameter of left atrium were 0.59 and 0.51, respectively. Conclusion: The increase of the included angle between the trachea and the left main bronchus (to the body axis) of the chest radiographs to some extent reflects the increase of the left atrium.
