Abstract:
Objective To analyze the changes of splenic volume and blood flow detected by ultrasonography in men having been migra-ted 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 com-pared 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.
