摘要
目的 探讨通过正常成人主肺动脉的超声测量诊断肺动脉高压与否的可能性。方法 连续测量14 9例正常成人主肺动脉直径 (内径 )并测量膈处降主动脉直径 (内径 )的比值 ,另外采用相同方法测量 17例 6 0～ 78岁一组经彩色 Doppler证实的慢性肺阻塞疾病 (chronic obstructive pulmonary disease,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 正常成人不同年龄主肺动脉直径不同并有随年龄增长而增大的趋势 (P<0 .0 5 ) ,其比值与年龄有关 (P<0 .0 5 ) ,且其比值与 COPD患者的比值比较存在显著差异 (P<0 .0 1)。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、敏感的指标。
Objective To explore the possibilities of diagnosing pulmonary hypertension by measurement of pulmonary trunk with ultrasound in normal adults.Methods There were two groups including 149 normal adults and 17 patients with chronic obstructive pulmonary disease(COPD)(age,over 60 years) confirmed by CT and colour Doppler.We measured respectively the internal diameters of the pulmonary trunk and descending aorta,calculated the ratio of the two and compared the data between the two groups.Results In the normal adults,the diameter of pulmonary trunk was different along with the age,and the diameter was larger as age increasing(P<0.05).The diamter ratio of the pulmonary trunk and descending aorta at the same level was relevant to the ageing(P<0.05).The ratios in the two groups were significantly different(P<0.01).Conclusions The diameter ratio of the pulmonary trunk and descending aorta in different ages may be considered as a simple,sensitive index for identifying pulmonary hypretension.
