Abstract:
Objective To explore the different changes of the adult cerebral blood flow with ages,different weight and gender,to summarize the changing characteristics of cerebral blood flow.Methods 360 cases of examination were divided into two groups according to gender,and were divided into five groups at different ages,and were divided into four groups according to body mass index,using TCD detector blood flow velocity.Results 196 cases of male physical examination,the mean cerebral blood flow was (969.37 ± 117.54)ml/min;the 164 females physical examination,the average cerebral blood flow was (987.76 ± 114.34)ml/min,there was no statistically significant difference (P ＞ 0.05).Different ages cerebral blood flow velocity were different,20 to 29-year-old group and the 30 to 39-year-old group had no significant difference (P ＞ 0.05) ;40 to 49-year-old group,50 to 59 years,60 to 69 years old ＞ 70 age group significantly declined compoued with the first two groups,there was significant difference (P ＜ 0.05) ;there were significant difference between the four groups (P ＜ 0.05).Overweight and obese group were significantly lower than the light and the normal group,there was a statistically significant difference (P ＜ 0.05).Conclusion TCDcan be a sensitive and accurate hemodynamic changes in the human brain,and is very important in the early diagnosis,prevention,treatment,and follow-up of cerebrovascular disease.
