摘　　要：目的用彩色多普勒超声(CDFI)观察短暂性脑缺血发作(TIA)患者颈动脉形态及血流动力学改变。方法用彩色多普勒超声观察了40例TIA患者颈动脉形态、结构和动力学改变,并与性别、年龄相匹配的40例健康人对照。结果TIA患者颈动脉内-中膜厚度较对照组明显增厚、内膜面粗糙,发现斑块25例,占62.5%,而对照组8例,占20%。同时发现TIA组平均血流速度减慢,搏动指数和阻力指数增高,血流量下降,提示TIA患者存在明显的颈动脉硬化。结论彩色多普勒检查可作为TIA病因诊断的一项无创伤性手段。Objective To observe the changes of morphology, hencodynamics and intracranial anevrysms of the carotid artery in Patients with（transient ischemic attack which were examined with Color Doppler flow imaging （CDFI）. Methods CDFI was used in Forty Patients with TIA（the experiment group ） and Forty healthy People （the control group） to observe the changes of morphology, hencodynamics and intraranial anevrysms. Results Compared with the control group. The intirna-medium thickness （IMT） of the carotid avtery in Patients with TIA increased significantly. In the experiment group, the intinia of carotid artery become rough, 25 cases of plaques （62.5%） were observed, while only 8 cases of Plaques（20%） were found in the control group. Meanwhile, the mean velocities decreased, Pulsitility Index （PI） and resistant index （RI） increased, Volume Flow decreased, which indicated that there existed obvious carotid Ahterosclerosis. Conclusion The CDFI could be taken as a non-invansive method of diagnosing TIA in terms of citology.
