Prevalence Investigation of Thromboangitis Obliterans and Arteriosclerosis Obliterans(ASO)in China

Objective:To study the prevalence of thromboangitis obliterans(TAO)and arteriosclerosis obliterans(ASO)in China Methods:From 1983 to 1998,10410 cases of TAO and 8843 cases of ASO from 13 hospitals of China were studied.In group one,2313 cases of TAO and 849 cases of ASO from 1983 to 1986,2869 cases of TAO and 1243 cases of ASO from 1987 to 1990,2271 cases of TAO and 1483 cases of ASO from 1991 to 1994,1653 cases of TAO and 1506 cases of ASO from 1955 to 1998 were analyzed.In group two ,272 cases of TAO and 2170 cases of ASO from 1986 to 1990,605 cases of TAO and 593 cases of ASO from 1991 to 1994,418 cases of TAO and 1044 cases of ASO from 1995 to 1998 were analyzed.Results: In groups one and two,the morbidity of TAO has been dramatically decreased in the recent 8 years.But in groups one and two,the morbidity of ASO has dramatically increased.Conclusion:The morbidity of TAO has been continuously decreased,and the morbidity of ASO has dramatically increased in China.
