Objective：To observe the distribution law of Chinese medicine constitution in patients with cerebrovascular trauma，and the relationship between patients with cerebrovascular trauma of different Chinese medicine constitutions and the hemodynamic indexes.M e th o d s： Selected 300 cases of patients with cerebrovascular trauma as study subjects， and classified them according to the standard of nine basic types of Chinese medicine constitutions proposed by Professor WANG Qi.Respectively counted the Chinese medicine constitutions of different genders and age groups，and compared the hemodynamic indexes of both the left and right side in patients of common Chinese medicine constitutions，including mean blood flow(Qmean)，mean velocity(Vmean)， characteristic impedance(Zcv)， peripheral resistance(RV)and dynamic resistance(DR).R e s u lts： The proportion of different Chinese medicine constitutions in patients with cerebrovascular trauma was ranked：phlegm-dampness constitution＞blood-stasis constitution＞qi-deficiency constitution＞qi-stagnation constitution＞yang-deficiency constitution＞dampness-heat constitution＞yin-deficiency constitution＞special intrinsic constitution＞balanced constitution.The proportion of phlegm-dampness constitution in male patients was higher than that in female patients，the difference being significant(P＜0.05).The highest proportion of Chinese medicine constitution in patients with cerebrovascular trauma in all age groups was phlegm-dampness constitution，followed by blood-stasis constitution.Levels of Qmean，Vmean，Zcv，RV and DR of the left side were better than those of the right side in patients of phlegm-dampness constitution(P ＜ 0.05).Levels of Qmean，Zcv，RV and DR of the left side were better than those of the right side in patients of dampness-heat constitution，blood-stasis constitution，qi-stagnation constitution or qi-deficiency constitution(P ＜ 0.05).Levels of Qmean，RV and DR of the left side were better than those of the right side in patients of yang-deficiency constitution(P＜0.05).C o n c lu s io n：Patients with cerebrovascular trauma are mainly of biased constitutions，and the phlegm-dampness and blood-stasis are susceptible factors.It's more common to see male patients of phlegm-dampness constitution than female patients.On the right side of the patients of susceptible constitutions have poor cerebrovascular elasticity，large blood viscosity and low blood flow velocity.
