摘　　要：目的测量健康人胸部大血管直径并计算其比值，探讨不同年龄、不同性别间胸部大血管直径正常值和比值的变化规律。方法应用多层螺旋CT（MSCT）测量356例16～80岁之间主肺动脉、升主动脉、降主动脉、主动脉根部直径，并计算主肺动脉／升主动脉、主肺动脉／降主动脉、升主动脉／降主动脉比值。结果不同年龄段各大血管直径有明显差异，P〈0．05；不同性别间各大血管直径有明显差异P〈0．05；不同年龄段主肺动脉／升主动脉比值、主肺动脉／降主动脉比值存在差异，P〈0．05，升主动脉／降主动脉比值无差异，P〉0．05；不同性别间主肺动脉／降主动脉、升主动脉／降主动脉有差异，P〈0．05，主肺动脉／升主动脉比值无差异，P〉0．05。结论随着年龄增长，胸部大血管管径增宽，表现为增龄性改变；男性胸部大血管直径明显大于女性；主肺动脉／升主动脉、主肺动脉／降主动脉比值随着年龄增长表现为递减趋势。Objective To measure the normal diameters and the ratio of thoracic large vessels in healthy adult, to explore the regularity of the normal diameters and ratio of thorax large vessels in different age and sex. Methods 356 cases ranged 16-80 years old in ages were involved in this study. The largest internal diameters of main pulmonary artery, ascending aorta,descending aorta and aortic root,the ratio of main pulmonary artery/ascending aorta, main pulmonary artery/descending aorta and ascending aorta/descending aorta were measured with MSCT. Results There were obvious differences in the diameters of large arteriae（P〈0.05 ） ,in the ratio of main pulmonary artery/ascending aorta,main pulmonary artery/descending aorta （P〈0.05）but not in ascending aorta/ descending aorta in different age groups. There were obvious differences in the diameter of large arteriae（ P〈0.05）, in the ratio of main pulmonary artery/descending aorta, ascending aorta/descending aorta in different sexes（P〈0.05 ）but not in the ratio of main pulmonary artery/ascending aorta（P〉0.05）. Conclusion The diameters of thorax large vessels are increased with aged;the diameters of large vessels in men are obviously larger than that in women;the ratio of main pulmonary artery/ascending aorta, main pulmonary artery/descending aorta show decreasing tendency with age.
