摘　　要：目的：探讨通过正常成人主肺动脉的ＨＲＣＴ测量诊断肺动脉高压与否的可能性。方法：连续测量２００例正常成人主肺动脉直径（外径）并计算其与同一层面降主动脉直径（外径）的比值，另外采用相同方法测量１１例６０～７８岁一组已经ＣＴ与彩色Ｄｏｐｐｌｅｒ证实的ＣＯＰＤ患者主肺动脉直径及与降主动脉直径的比值并与正常组比较。结果：正常成人不同年龄，不同性别主肺动脉直径不同并有随年龄增长而增大的趋势（Ｐ＜０．０５），但其比值与年龄有关（Ｐ＜０．０５）与性别无关（Ｐ＞０．０５），其比值与ＣＯＰＤ患者的比值比较存在显著差异（Ｐ＜０．０１）。结论：正常成人不同年龄组主肺动脉与降主动脉的比值可作为判断肺动脉高压与否的简单。Objective:To explore the possibilites of diagnosing pulmonary hypertension by measurement of pulmonary trunk with HRCT in normal adults.Metheds:There were two groups including 200 normal adults and 11 patients with COPD who in age were over 60 years and confirmed by CT and Colour Doppler.We measured respectively the external diameter of pulmonary trunk and descending aorta at the same level serially and calculated their ratio and compared the difference between the two groups.Results:In the normal adults,the diameter of pulmonary trunk was different in different age and sex,and the diameter was became large as aging(P<0.05).The ratio of the diameter of pulnonary trunk and descending aorta at the same level was relevant to the age(P<0.05)not to the sex(P>0.05).The ratio of the two groups was significantly different(P<0.01).Conclusions:The ratio of the diameter of pulmonary trunk and descending aorta in different age can be considered as a simple,sensitive index identifying pulmonary hypretension.
