摘　　要：目的分析超声检测移居高原10年男性脾脏体积与血流量变化及两者之间的相关性。方法移居高原10年男性、平原地区健康男性和世居高原男性各55名,以3~5 MHz凸阵探头进行脾脏扫查,测量脾脏长、宽、厚3条径线,计算其体积,以彩色多普勒血流显像测量脾动脉内径与平均流速,计算其血流量。比较3组脾脏体积、血流量的差异,并分析两者之间的相关性。结果移居高原男性脾脏体积与血流量明显高于平原地区健康男性和世居高原男性（P〈0.01）,后两者无显著差异;脾脏血流量与体积间呈正相关（r=0.828,P〈0.01）。结论移居高原10年男性脾脏与血流量明显增高,且两者密切相关;超声在我国高海拔地区脾脏生理病理变化的检测具有重要作用。Objective To analyze the changes of splenic volume and blood flow detected by ultrasonography in men having been migrated in high-altitude area for 10 years and to explore the relationship between the splenic blood flow and volume. Methods Men migrating to high-altitude area for 10 years,male indigenous Tibetan and healthy men from planitia with 55 cases in each were involved. Ultrasonography was performed to measure the length,width and thickness of spleen to calculate the volume,and color Doppler flow imaging was applied to measure the diameter of splenic artery and the mean flow velocity to calculate the blood flow volume. The differences among groups were compared and the relationship between the blood flow and the volume was analyzed. Results The blood flow and the volume of spleen in men migrating to high-altitude area were higher than those in male indigenous Tibetan and healthy men from planitia（ P〈0. 01）,and the blood flow was positively correlated with the splenic volume（ r = 0. 828,P〈0. 01）. Conclusion The splenic volume and blood flow are increased in men when have been migrated in high-altitude area for 10 years and ultrasonography is of great importance in detecting the pathophysiologic changes in high-altitude area in our country.
