【摘要】 目的通过对高海拔与低海拔居民胸部大血管的CT测量,分析高海拔居民和低海拔居民的心血管的差异及价值。方法100例高海拔居民,100例低海拔居民采用CT进行胸部平扫,对2组胸部大血管径线进行了测量和观察。结果高海拔组主动脉弓横径均值为(2.59±0.30)cm,低海拔组为(2.73±0.76)cm,高海拔组右下肺静脉横径均值为(1.00±0.30)cm,低海拔组为(1.19±0.34)cm。左下肺动脉横径均值为(1.30±0.28)cm,低海拔组为(1.2±0.34)cm。结论肺动脉血管横径高海拔居民大于低海拔居民组。低海拔组体循环大动脉血管和肺静脉血管横径大于高海拔人群组。更多还原

【Abstract】 Objective The diffferences of the cardiovasular transverse between sea-level and high altitude residents was analysed, by measuring thoracic great vessels diameter with CT scanning .Methods 100 cases residents of high altitude and 100 cases sea-level residents were scaned by CT in lung, and the cardiovascular and pulmonary arterial diameter were measured .Results In high altitude groupe the average transverse diameter(ATD) of aortic arch was (2.59±0.30)cm but in control groupe, ATD was (2.73±0.40)cm. The ATD of right pulmonary veins in high altitude was (1.00±0.30)cm but that of control was(1.19±0.34)cm. The ATD of left subpulmonary arteries in high altitude groupe was (1.30±0.28)cm and that of control was (1.2±0.43)cm.Conclusion The transverse diameter(TD)of pulmonary arteries was larger than those of the control . The TD of great arteries of systemic circuit and pulmonary veins were larger in sea-level residents than those of residents of high altitude.更多还原
